Answer: To find the numbers that Deshaun could choose, we need to find the least common multiple (LCM) of 4, 7, and 14. The LCM is the smallest number that is a multiple of all the given numbers.

We can find the LCM using the prime factorization method:

4 = 2^2

7 = 7

14 = 2 * 7

The least common multiple of 4, 7, and 14 is 2^2 * 7 = 28

So, the numbers Deshaun could choose are multiples of 28, which means they must be in the form of 28n, where n is a positive integer.

The numbers between 49 and 95 that are multiples of 28 are: 56, 84

So the numbers that Deshaun could choose are 56, 84.

The quadratic equation 4 · x² - 7 · x = 3 · x + 24 has the following roots: x₁ = 19 / 4 and x₂ = - 9 / 4.

In this question we find the case of a quadratic equation, whose form is defined below:

y = a · x² + b · x + c

Where:

The procedure find the solutions to the quadratic equations:

Now we proceed to determine the solutions to the quadratic equation:

4 · x² - 7 · x = 3 · x + 24

4 · x² - 10 · x - 24 = 0

4 · [x² - (5 / 2) · x - 6] = 0

4 · [x² - (5 / 2) · x + 25 / 4] = 4 · 6 + 4 · (25 / 4)

4 · (x - 5 / 4)² = 49

(x - 5 / 4)² = 49 / 4

x - 5 / 4 = ± 7 / 2

x = 5 / 4 ± 7 / 2

The solutions to the quadratic equation 4 · x² - 7 · x = 3 · x + 24 are x₁ = 19 / 4 and x₂ = - 9 / 4.

Answer: To find the percent of the decrease in the number of laps jogged from Saturday to Sunday, we can use the following formula:

percent decrease = (change in value / original value) x 100

In this case, the original value is the number of laps jogged on Saturday, which is 21 laps. The change in value is the difference in the number of laps jogged from Saturday to Sunday, which is 21 - 16.5 = 4.5 laps.

So, substituting these values into the formula:

percent decrease = (4.5 / 21) x 100

percent decrease = 0.214 x 100

percent decrease = 21.4%

Rounded to the nearest tenth, the percent of decrease in the number of laps jogged from Saturday to Sunday is 21.4%.

open up the cylinder so its top & bottom circle's circumference = 2πr =4π

top & bottom circle's area = πr² = 4π each, 8π for both

The value of g in the following equation is 6.25. The solution has been obtained using trigonometry formula.

What is trigonometry?

The primary objective of the branch of mathematics known as "trigonometry" is the study of the sides, angles, and connections of the right-angle triangle. Therefore, applying the trigonometric formulas, functions, or trigonometric identities aids in locating the unknown or missing angles or sides of a right triangle. In trigonometry, angles can be stated in either degrees or radians. For calculations, the most common trigonometric angles are 0, 30, 45, 60, and 90 degrees.

We are given g sin 34° =3.5

⇒ g = 3.5/sin34°     (Dividing both sides by sin34°)

Now, value of sin34° = sin(30+4)° = 0.5592

So, we get

⇒ g = 3.5/0.5592

⇒ g = 6.25

Hence, the value of g in the following equation is 6.25.

If the trend continued, the number of CDs that were sold in 2019 is approximately equal to: D. 2,000​.

In order to write a linear function that models the data point contained in the table and determine the slope, we would have to use the point-slope form to determine the line of best fit based on the data points provided on the scatter plot (see attachment).

Mathematically, the point-slope form of a straight line can be calculated by using this mathematical expression:

y - y₁ = m(x - x₁) or y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)

Where:

y - 800 = (700 - 800)/(2005 - 2002)(x - 2002)

y = 33.33(x - 2002) + 800

y = 33.33x - 65,266

When x = 2019, the number of CDs sold is given by:

y = 33.33(2019) - 65,266

The function f(x) = -9x^3 is odd because it is not at the initial state after replacing x by -x.

By taking a function, replacing each x with an equal value, simplifying it, and then comparing the outcomes to what you had initially, you can "determine algebraically" whether it is even, odd, or neither.

If the function is identical to what you started with that is, if f(-x) = f (x), with all the signs remaining the same then the function is even. If the function is exactly the opposite of what you started with (i.e., if f(-x) = -f(x), with all the signs switched this is known as an odd function.

The function is f(x) = -9x^3

Now substitute -x in place of x.

f(-x) = -9(-x)^3

f(-x) = -9 × -(x)^3

f(-x) = 9x^3

As we can see that the function is not in the initial position so the function is odd.

The largest possible value for the probability of A4 is 0.3.

If events A1, A2, A3, and A4 are pairwise mutually exclusive with the exception that A1 and A2 occur simultaneously, then the probability of A1 and A2 occurring together is 0.1. This means that the probability of A1 occurring separately is 0.3 - 0.1 = 0.2, and the same is true for A2.

Since A1, A2, A3, and A4 are pairwise mutually exclusive, the probability that they all occur together is 0. Therefore, the sum of their individual probabilities is also 0. Therefore, the probability of A4 is the remaining probability after accounting for the probability of A1, A2, and A3. The largest possible value for the probability of A4 is the total probability minus the probability of A1, A2, and A3.

So, the largest possible value for the probability of A4 would be:

1 - (0.2 + 0.2 + 0.3) = 1 - 0.7 = 0.3

Therefore, the largest possible value for the probability of A4 is 0.3.

The probability that at least one of 10 randomly chosen Americans has O-negative blood is 0.722.

The probability that at least one of 10 randomly chosen Americans has O-negative blood can be calculated by first determining the probability that none of them have O-negative type blood. Since 7.2% of the population has O-negative blood, the probability that one of 10 randomly chosen Americans has O-negative blood is (1 - 0.072)^10. To determine the probability that at least one of 10 randomly chosen Americans has O-negative blood, we subtract this value from 1. Therefore, the probability that at least one of 10 randomly chosen Americans has O-negative blood is 1 - (1 - 0.072)^10, which is equal to 0.722.

So, the last three digits of m*n is 001.

Let p be the probability that Alfred wins given that he goes first. Then, the probability that Bonnie wins given that she goes first is 1-p. Therefore, the probability that Alfred wins the second game given that Bonnie went first in the first game is 1-p. Similarly, the probability that Alfred wins the third game given that he went first in the second game is p, and so on.

Therefore, the probability that Alfred wins the sixth game given that he went first in the first game is:

p(1-p)(1-p)(p)(p)(p) = p^4 (1-p)^2

Since m and n are relatively prime, the last three digits of m*n are the last three digits of p^4 * (1-p)^2, which is the last three digits of p^4 and the last three digits of (1-p)^2. Since p is the probability of winning given that you go first, it is a number between 0 and 1. Therefore, the last three digits of p^4 and (1-p)^2 are 001, resulting in the last three digits of the final answer being 001.

Answer: The PMT function in Sheets is used to calculate the monthly payment for a loan. The syntax of the function is PMT(rate, nper, pv, [fv], [type]).

Rate: the interest rate per period

Nper: the total number of payments

Pv: the present value (the total amount of the loan)

Fv: the future value of the loan (optional)

Type: the number 0 or 1 indicating when payments are due (0 = end of period, 1 = beginning of period)

Given the information in the problem, Ben's mortgage is for 10 years, so the total number of payments is 10*12 = 120. The present value of the loan is $196000 and the down payment is 25% of the home's cost so 25%*196000 = $49000. Therefore, the present value of the loan is $196000 - $49000 = $147000

Based on this information, the following commands would be used to determine the monthly payment:

PMT(0.076/12,120,-$147000)

PMT(0.076/12,120,-196000+$49000)

The first command uses the annual interest rate divided by 12 to convert it to a monthly rate, and the total number of payments is 120 (10 years * 12 months/year). The second command also uses the same monthly rate and total payments and the present value which is $147000

Applying the sum of angles on a straight line, we have:

Equation = x + 70 + 60 = 180

Measure of x = 50°.

In geometry, an angle is formed when two rays are joined at their endpoints. These rays are called the sides or arms of the angle.

A straight line angle equals 180 degrees.

Therefore, the sum of all the angles on a straight line = 180 degrees.

Thus, the equation to solve for x would be:

x + 70 + 60 = 180

Solving for x

x + 130 = 180

x = 180 - 130

x = 50°
