The critical value for the confidence interval will be 2.33 with a confidence inetrval of 0.05 ± 0.00308

Here we see that the probability to find a bulb from the sample broken is

p = 25/500

= 0.05

Now, we need to build a 98% confidence interval so we will get the critical value to be

(1 - confidence interval)/2

= (1 - 0.98)/2

= 0.02/2

= 0.01

Looking up the value for 0.01 in the standard normal table we the critical value to be

2.33

Now the confidence interval will be

p ± critical value X √[p(1 - p)/n]

= 0.05 ± 0.01√[(0.5 X 0.95)/500]

= 0.05 ± 0.00308

The answer is 4.4753, i.e. the critical value of the statistic upto four decimal places.

Null hypothesis (H0): σ21 = σ22

Alternative hypothesis (H1): σ21 > σ22

Round your answer(s) to four decimal places.

Critical value = 4.4753

Test statistic = 34.66/6.3 = 5.5

The test statistic (5.5) is greater than the critical value (4.4753), so we reject the null hypothesis and accept the alternative hypothesis.

The value of x is 30 degrees.

A right-angled triangle is a type of triangle that has one angle that measures exactly 90 degrees (a right angle). This angle is formed by the intersection of the two sides of the triangle that are perpendicular to each other, which are called the legs or the adjacent and opposite sides. The side opposite the right angle is called the hypotenuse, and it is always the longest side in the triangle. The other two sides are usually labeled as a and b, and are called the legs or the adjacent and opposite sides depending on which angle is being considered. The Pythagorean theorem, which states that the sum of the squares of the two legs of a right triangle is equal to the square of the hypotenuse, is one of the fundamental properties of right-angled triangles. Right-angled triangles have numerous practical applications in geometry, trigonometry, physics, and engineering.

We can use the trigonometric ratio of sine to find the angle x.

sin(x) = opposite/hypotenuse = PQ/PR = 48/96 = 1/2

Taking the inverse sine of both sides, we get:

x = sin^(-1)(1/2)

Using a calculator, we get:

x ≈ 30 degrees

Therefore, the value of x is 30 degrees.

Answer:

The probability of selecting a face card or a spade when randomly selecting one card from a standard deck of cards is 11/26 or approximately 0.423.

Step-by-step explanation:

Part A

No, selecting a face card and selecting a spade when randomly selecting one card from a standard deck of cards are not mutually exclusive events. This is because there are face cards that are also spades, so there is an overlap between the two events.

Part B

The probability of selecting a face card or a spade when randomly selecting one card from a standard deck of cards can be calculated as follows

P(face card or spade) = P(face card) + P(spade) - P(face card and spade)

Part C

The probability of selecting a face card or a spade when randomly selecting one card from a standard deck of cards can be calculated as follows

P(face card or spade) = P(face card) + P(spade) - P(face card and spade)

P(face card or spade) = 12/52 + 13/52 - 3/52

P(face card or spade) = 22/52

P(face card or spade) = 11/26

Hence, the probability of selecting a face card or a spade when randomly selecting one card from a standard deck of cards is 11/26 or approximately 0.423.

(x + 2)2 + (y - 4)2 - 11 = 0

The equation of the circle in standard form is x2 + y2 + 36x - 72y + 11 = 0. To arrive at this answer, you need to complete the square for both the x and y terms in the equation. First, divide the equation by 9 to get the following:

x2 + y2 + 4x - 8y + 1 = 0

To complete the square for the x terms, add and subtract (4/2)2 = 16/4 = 4 to the equation:

x2 + 4 + y2 + 4x - 8y + 1 - 4 = -4

Simplifying gives you:

(x + 2)2 + y2 - 8y + 5 = 0

To complete the square for the y terms, add and subtract (8/2)2 = 64/4 = 16 to the equation:

(x + 2)2 + (y - 4)2 + 5 - 16 = -11

Simplifying gives you:

(x + 2)2 + (y - 4)2 - 11 = 0

This is the equation in standard form.

1 kilogram of soil will fit in the container, since 1 kilogram is less than 27/5 kilograms.

We can start by using ratios to solve this problem.

From the information given, we know that:

We want to know how much soil will fit in the entire container (which is equivalent to 3 times the amount that fills 1/3 of the container)

To find out how much soil fills the entire container, we can set up a ratio:

(3/5 kg of soil) : (1/3 of container) = (x kg of soil) : (1 container)

We can cross-multiply to solve for x:

(3/5 kg of soil) * (1 container) = (1/3 of container) * (x kg of soil)

Multiplying both sides by 3/1 gives:

(3/5) * 3 * (1 container) = (1/3) * x

Simplifying gives:

9/5 = 1/3 * x

Multiplying both sides by 3 gives:

Answer:

Add to eliminate X

Step-by-step explanation:

To eliminate a variable, we need to make its coefficient equal and opposite in the two equations. In this case, we can see that the coefficient of x in both equations is the same (6x), so we can eliminate x by adding the two equations.

When we add the two equations, the x term will cancel out, leaving us with the equation:

9y = 36

We can then solve for y by dividing both sides by 9:

y = 4

Now that we know the value of y, we can substitute it back into one of the original equations to solve for x. Let's use the first equation:

6x + 5y = 12

6x + 5(4) = 12

6x + 20 = 12

6x = -8

x = -4/3

Therefore, the solution to the system of equations is x = -4/3, y = 4.

Answer: Its B.) −5 ≤ y ≤ 2

Step-by-step explanation: The graph shows one part of the interval increasing which is the y value and stops at 3. The X interval which is the decreasing interval stops at -5. So this would be -5 greater then or equal to y greater then or equal to 2.

The workman's hourly rate of pay for a 40-hours week is 380.

Hourly rate of pay = Total pay ÷ Total hours worked

Hourly rate of pay = 15, 200 ÷ 40 = 380

Therefore, the workman is paid 380 per hour for a 40-hours week. To calculate the hourly rate of pay, the total pay is divided by the total hours worked. In this case, the total pay is 15, 200 and the total hours worked is 40, so when we divide 15, 200 by 40, we get 380. This is the hourly rate of pay for the workman for the 40-hours week.

Polynomial multiplication is the process of multiplying two polynomials together to get a new polynomial that represents the product of the two original polynomials.

It should be noted that to multiply two polynomials, you need to perform a distributive operation. You take each term of the first polynomial and multiply it by each term of the second polynomial. Then, you add all the resulting terms together to get the final polynomial.

For example, let's say you want to multiply the polynomials (x + 2) and (x - 3).

First, you multiply the x term in the first polynomial by the x term in the second polynomial:

(x) * (x) = x²

Next, you multiply the x term in the first polynomial by the -3 term in the second polynomial:

(x) * (-3) = -3x

Then, you multiply the 2 term in the first polynomial by the x term in the second polynomial:

(2) * (x) = 2x

Finally, you multiply the 2 term in the first polynomial by the -3 term in the second polynomial:

(2) * (-3) = -6

Now, you add up all the resulting terms to get the final polynomial:

x² - x - 6

Therefore, the product of (x + 2) and (x - 3) is x² - x - 6.

A math equation is a mechanism for connecting statements and indicating equivalence with both the equals symbol (=). An equation is an algebraic claim that asserts the equivalency of two formulae in algebra. In the calculation 3x + 5 = 14, for example, the equivalence sign separates the numbers 3x + 5 and 14. To explain the relationship among the two words on each surface of a letter, a formula can really be employed. The software and the logo are usually interchangeable. For instance, 2x - 4 equals 2.

Set T = 300 in the equation and solve for t to discover the number of minutes it takes for the oven's temperature to reach 300°F:

T = 400 - It

300 = 400 - It / subtraction T = 300

It = 400 - 300

It = 100

t = 100 / I

T = 400 minus It I = (400 minus T) / t

When we substitute T = 0 and T = 1, we get:

I = (400 - 0) / 1\sI = 400

Now we can substitute I = 400 into the equation we found before for t:

t = 100 / I\st = 100 / 400\st = 0.25

As a result, it takes around 0.25 minutes for the oven to reach 300°F, or roughly 15 seconds. Rounded to the closest minute, the answer is 0 minutes.
