Answer:

B

Step-by-step explanation:

In answer choice B, there is the same number of medium bottles as the number of medium bottles that you are given in the question.

Because you know that there are 93 fluid ounces in six small bottles and four medium bottles, you know that any different amount of fluid ounces with the answer choice would be because of the increase in small bottles.

By having a consistent change with only one variable (which is the small bottle) you can find the rate of change. Once you figure out how many fluid ounces are in the small bottles, you can find the total amount of fluid ounces that are in the small bottles. The amount that remains is the total fluid ounces for medium bottles.

The two z-scores that separate the middle 87.4% of the distribution from the area in the tails of the standard normal distribution are -1.46 and 1.46.

To find these z-scores, we need to first determine the area in the tails of the distribution. Since the middle 87.4% of the distribution is separated from the tails, the area in the tails is 100% - 87.4% = 12.6%. This means that there is 12.6% / 2 = 6.3% in each tail.

Next, we can use a standard normal table or a calculator to find the z-scores that correspond to the 6.3% in the tails. We want to find the z-scores that have an area of 0.063 to the left and to the right of them.

According to a standard normal table, the z-score that has an area of 0.063 to the left of it is -1.46, and the z-score that has an area of 0.063 to the right of it is 1.46.

Therefore, the two z-scores that separate the middle 87.4% of the distribution from the area in the tails of the standard normal distribution are -1.46 and 1.46.

Answer:

Step-by-step explanation:

To determine whether (3, 20) is a solution of y = 4x + 8, we need to substitute x = 3 and y = 20 into the equation and check whether the equation is true:

y = 4x + 8

20 = 4(3) + 8

20 = 12 + 8

20 = 20

Since the equation is true, we can say that (3, 20) is a solution of y = 4x + 8.

Answer:

Step-by-step explanation:

y= 4x+8

substituting x=3,

y= 4(3)+8

y= 12+8

y=20

∴ (3,20) is a solution of y= 4x+8

Around 76.5% of the 200 students polled said they would eat two or three servings, with 48.2% saying they would eat two and 28.3% saying they would eat three.

To get the percentage of students who select two or three servings, we must first add the 48 and 73 students who select two and three servings, respectively, for a total of 121 students.

The percentage is then calculated by dividing this sum by the total number of students polled (200), and multiplying the result by 100: (121/200) x 100 = 60.5%

As a result, 2. or 3. servings were selected by 60.5% of the students questioned. It's important to note that this estimate makes the assumption that each student will only select one option (2 servings or 3 servings), not both.

a. From the cumulative standardized normal distribution table, we can look up the value 1.56 in the left column and find the corresponding value of 0.9406 in the intersecting row. Therefore, the probability that Z is less than 1.56 is 0.9406.

b. From the cumulative standardized normal distribution table, we can look up the value 1.81 in the left column and find the corresponding value of 0.9641 in the intersecting row. Since we want the probability that Z is greater than 1.81, we subtract this value from 1 to get 1 - 0.9641 = 0.0359 (rounded to four decimal places as needed). Therefore, the probability that Z is greater than 1.81 is 0.0359.

c. To find the probability that Z is between 1.56 and 1.81, we need to subtract the probability that Z is less than 1.56 from the probability that Z is less than 1.81. From the table, we know that the probability that Z is less than 1.56 is 0.9406 and the probability that Z is less than 1.81 is 0.9641. Therefore, the probability that Z is between 1.56 and 1.81 is 0.9641 - 0.9406 = 0.0235 (rounded to four decimal places as needed).

d. The probability that Z is less than 1.56 or greater than 1.81 is the sum of the probabilities that Z is less than 1.56 and Z is greater than 1.81, since these events are mutually exclusive. From parts (a) and (b), we know that the probability that Z is less than 1.56 is 0.9406 and the probability that Z is greater than 1.81 is 0.0359.

Answer: The equation of a line can be written in slope-intercept form as:

y = mx + b

where m is the slope and b is the y-intercept.

We are given that the line has a slope of -3 and passes through the point (2, 2). We can use the point-slope form of the equation of a line to find the equation of this line:

y - y1 = m(x - x1)

where (x1, y1) is the given point and m is the slope.

Substituting the given values, we get:

y - 2 = -3(x - 2)

Expanding the right side:

y - 2 = -3x + 6

Adding 2 to both sides:

y = -3x + 8

Therefore, the equation of the line that has a slope of -3 and passes through the point (2, 2) is:

Step-by-step explanation:

1/(sec - tan) - 1/cos = 1/cos - 1(sec + tan)

=> 1/(sec - tan) + 1(sec + tan) = 1/cos + 1/cos

Left side

(sec + tan)/[(sec - tan)(sec + tan)] + (sec - tan)/[(sec - tan)(sec + tan)]

= [sec + tan + sec - tan]/[(sec - tan)(sec + tan)]

= [2sec]/[(sec - tan)(sec + tan)]

since (a+b)(a-b) = a^2 - b^2

=> 2sec/(sec^2 - tan^2)

let's work on the denominator (sec^2 - tan^2)

we know sec = 1/cos and tan = sin/cos

=> (1/cos)^2 - (sin/cos)^2

=> 1/cos^2 - sin^2/cos^2

=> (1 - sin^2)/cos^2 = cos^2/cos^2 = 1

so 2sec/(sec^2 - tan^2) => 2sec/1

=> 2sec

since sec = 1/cos => 2sec = 2(1/cos) = 2/cos

Right side

1/cos + 1/cos = 2/cos

For rectangle type books,  the difference in the heights of their stacks of books is 15 3/4 inches.

What exactly is a rectangle?

A rectangle is a type of quadrilateral (a four-sided polygon) that has four straight sides and four right angles. It is a two-dimensional shape, meaning it lies flat in a plane, and is defined by its two sets of parallel sides, each pair of which are equal in length.

In a rectangle, opposite sides are parallel and congruent (equal in length), and adjacent sides are perpendicular (meet at a right angle). The diagonals of a rectangle bisect each other (divide each other into two equal parts) and are congruent.

The area of a rectangle is calculated by multiplying its length and width, while its perimeter is found by adding the lengths of all its sides. The formula for the area of a rectangle is A = l x w, where A is the area, l is the length, and w is the width. The formula for the perimeter of a rectangle is P = 2l + 2w, where P is the perimeter, l is the length, and w is the width.

Now,

To solve this problem, we need to first find out the height of Rick's stack of books. We know that his stack is 3 times as tall as Trevor's stack, so:

Rick's stack = 3 x Trevor's stack

Rick's stack = 3 x 7 7/8 inches

Rick's stack = 23 5/8 inches

Now that we know the height of both stacks, we can find the difference between them:

Difference = Rick's stack - Trevor's stack

Difference = 23 5/8 inches - 7 7/8 inches

Difference = 15 6/8 inches

Difference = 15 3/4 inches

Therefore, the difference in the heights of their stacks of books is 15 3/4 inches.

The area of the shape that includes squares will be 9 m² and perimeter will be 16m.

What are squares?

A square has four equal sides and four right angles. It is a special type of rectangle, and like rectangles, it is also a two-dimensional shape with all its sides lying in a plane.

A square has several important properties. Its sides are equal in length, and its diagonals are congruent (equal in length) and bisect each other at right angles. All angles in a square are also right angles, which means that it is a special type of rectangle where all angles measure 90 degrees.

The area of a square is calculated by squaring the side. For example, if a square has a side length of s, its area would be A = s². The perimeter of a square is found by adding up the lengths of all four sides, which is P = 4s.

Now,

The sides of the squares will be 2m, 2m and 1 m.

then area of the figure will be =2²+2²+1²

=4+4+1

and

Perimeter = sum of all sides

then Perimeter=5+2+2+2+2+1+1+1

Proved that if the function f(x,y)=e^(ax+by) with a^2+b^2=1, then f''(xx)+f''(yy)=1

To find the second partial derivatives of f(x, y), we differentiate f(x, y) twice with respect to x and y:

f'(x, y) = ae^(ax + by) and f''(xx) = a^2e^(ax + by)

f'(x, y) = be^(ax + by) and f''(yy) = b^2e^(ax + by)

Adding these second partial derivatives, we get:

f''(xx) + f''(yy) = a^2e^(ax + by) + b^2e^(ax + by)

Since a^2 + b^2 = 1, we have:

f''(xx) + f''(yy) = e^(ax+by)

But f(x, y) = e^(ax+by), so:

f''(xx) + f''(yy) = f(x, y)

Therefore, we have proved that f''(xx) + f''(yy) = 1.

Answer:

47 - 6√10

Step-by-step explanation:

Area of a square of side a = a²

Here a = √2 -3√5

Area A = a² = (√2 -3√5)²

We know that (a - b)² = a² -2ab +b²

So

A = (√2 -3√5)²

= (√2)² - 2(√2)(3√5) + (3√5)²

(√2)² = 2   because (√a)² = a

(3√5)² = 3² x (√5)² = 9 x 5 = 45

2(√2)(3√5) = 2 (√2 · 3 · √5)

= 2 x 3 √2 √5

√2√5 = √10

2 x 3 √2 √5 = 2 · 3 · √10 = 6√10

Therefore area = 2 - 6√10 + 45

= 47 - 6√10

The probability of either A or B occurring is 0.55625.

The probability of either A or B occurring when given that events A and B are independent, and P(A) = 0.25 and P(B) = 0.45, can be calculated as follows: 0.25 + 0.45 - 0.25*0.45= 0.55625.:

When the events A and B are independent, then the probability of the two events occurring together is given as:P(A ∩ B) = P(A) × P(B)This is a formula for independent events, and when events A and B are independent, it implies that P(A ∩ B) = 0.

Therefore:P(A ∪ B) = P(A) + P(B) - P(A ∩ B)When the probability of A and B is given as P(A) = 0.25 and P(B) = 0.45, we can substitute these values in the above equation as:P(A ∪ B) = P(A) + P(B) - P(A) × P(B)Thus:P(A ∪ B) = 0.25 + 0.45 - 0.25*0.45= 0.55625Therefore, the probability of either A or B occurring is 0.55625.

The height of the cone is 11 mm and the slant height of the cone is 23 mm and the ant crawls 31 mm to get from the base of the cone to the top of the hill.

What is the volume of the right circular cone?

A right circular cone is a three-dimensional geometric shape that has a circular base and a vertex that is located directly above the center of the base. The axis of the cone is a line that passes through the vertex and the center of the base.

The volume of a right circular cone can be found using the formula:

[tex]V = (1/3)\pi r^2h[/tex]

where V is the volume of the cone, r is the radius of the circular base, and h is the height of the cone.

1) To find the height of the cone, we need to use the formula for the volume of a cone, which is [tex]V = (1/3)\pi r^2h[/tex]. Rearranging this formula, we get:

[tex]h = 3V / \pi r^2[/tex]

Substituting the given values, we get:

[tex]h = 3(8792) / (3.14)(20^2)[/tex]

h ≈ 11

Therefore, the height of the cone is approximately 11 mm.

2) To find the slant height of the cone, we can use the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides.

In the case of the cone, the slant height is the hypotenuse of a right triangle formed by the height and the radius of the base. Therefore, we have:

[tex]s^2 = r^2 + h^2[/tex]

Substituting the values we found in part 1, we get:

[tex]s^2 = 20^2 + 11^2[/tex]

s ≈ 23

Therefore, the slant height of the cone is approximately 23 mm.

3) To find the distance the ant crawls to get from the base of the cone to the top of the hill, we can use the Pythagorean theorem again. This time, we need to find the distance along the slant height from the base of the cone to the top of the hill. This distance is the hypotenuse of a right triangle formed by the distance from the base to the apex (which is the height of the cone) and the radius of the base. Therefore, we have:

[tex]d^2 = r^2 + s^2[/tex]

Substituting the values we found in parts 1 and 2, we get:

[tex]d^2 = 20^2 + 23^2[/tex]

d ≈ 31

Therefore, the ant crawls approximately 31 mm to get from the base of the cone to the top of the hill.

The dilation is an enlargement, and Tashi is correct.

To determine whether the dilation (scaling) is a reduction or an enlargement, we need to compare the distances between corresponding points on the original figure and the dilated figure.

Suppose a point P(x,y) is on the original figure. After the dilation with the rule (6/5x, 6/5y), the corresponding point P'(x', y') will be:

P' = (6/5x, 6/5y)

The distance between point P and the origin is given by:

d(P) = √(x² + y²)

The distance between point P' and the origin is:

d(P') = √((6/5x)² + (6/5y)²)

= 6/5 * √(x² + y²)

Since the dilation multiplies each coordinate by a factor of 6/5, the distance between any point and the origin is multiplied by a factor of 6/5.

Therefore, if 6/5 < 1, then the distances between corresponding points are reduced, and the dilation is a reduction. If 6/5 > 1, then the distances are increased, and the dilation is an enlargement.

In this case, we have:

6/5 > 1

Therefore, the dilation is an enlargement, and Tashi is correct.

The Pacific Ocean is roughly 100 times bigger than the Gulf of Mexico.

Ocean is the largest and most prominent feature of the Earth's surface. It covers more than 70% of the planet and contains 97% of its water. Oceans are vital to life on Earth, providing food and resources, regulating the climate, and supporting a vast array of marine life.
