The probability that not more than 5 graduates plan to pursue a graduate degree is 0.0191.

Given Information

Percentage of college graduates that plan on pursuing a graduate degree=50%

Number of graduates selected=14

Let us consider the event that a college graduate plans on pursuing a graduate degree as a success.

The probability of getting success is p = 0.50

Let X denotes the event of success.

We have, n = 14.

Then,

X∼Bin(14,0.50).

The pmf of X is given as,

[tex]P(X)= ^nC_xP^x(1-P)^n^-^x\\\\P(X)= ^1^4C_x(0.50)^x(0.50)^1^4^-^x[/tex]

The probability that not more than 5 graduates plan to pursue a graduate degree can be computed as,

P(X≤5)=5∑¹⁴Cₓ(0.50)x(0.50)¹⁴⁻ˣ

=0+0.00001+0.00012+0.00081+0.00396+0.01425

P(X≤5)=0.01914

Hence, the probability that not more than 5 graduates plan to pursue a graduate degree is 0.0191.

The probability that exactly 7 of the college graduates plan to pursue a graduate degree can be computed as,

P(X=7)=¹⁴C₇(0.5)⁷(0.5)⁹

P(X=7)=0.08395

Therefore, the probability that exactly 7 of the college graduates plan to pursue a graduate degree is 0.0840.

The probability that at least 9 but not more than 14 of the college graduates plan to pursue a graduate degree can be computed as,

P(9≤X≤14)=14∑x=9 ¹⁴Cₓ(0.50)x(0.50)¹⁴⁻ˣ

P(9≤X≤14)=0.18889+0.19833+0.16227+0.10142+0.04681+0.01505

A. The slope of the line is 40

B. The equation of the line is 40x - y + 600 = 0

C. The equation is g(x) = 4x + 600        

The balance is 628 Rs.

The formula of the slope of line = Δy/Δx

                                             = 720 - 600 / 3 - 0

                                             = 120/3

                                             = 40

The equation of a line is given as y - y₁ = m(x - x₁)

m = 40 which is the slope.

When we substitute we have

y - 600 = 40(x - 0)

We have to substitute x as 0

y - 600 = 0

y = 600

therefore y = 40x + 600

This implies that 40x - y + 600 = 0

c.  y - 600 = 40x    

g(x) - 600 = 4x

hence

g(x) = 4x + 600

The number of integrals required in the shell method is one or two, depending on the axis of rotation and the dimension of the solid of revolution.

The number of integrals required in the shell method depends on the dimension of the solid of revolution being generated. The shell method generates a solid of revolution by rotating a region about an axis.

For a solid of revolution generated by rotating a two-dimensional region about a vertical axis (i.e., a vertical shell), two integrals are required: one to find the volume of the shell and another to add up the volumes of all the shells to get the total volume of the solid.

Dividing the sum of `(-12)/(5) and (-18)/(15)` by their difference. The answer is 3.

To divide the sum of two numbers by their difference, we first need to find the sum and the difference of the two numbers.

The sum of (-12)/(5) and (-18)/(15) is:

(-12)/(5) + (-18)/(15) = (-12)/(5) + (-6)/(5) = -18/5

The difference of (-12)/(5) and (-18)/(15) is:

(-12)/(5) - (-18)/(15) = (-12)/(5) - (-6)/(5) = -6/5

Step-by-step explanation:

The car salesperson made $62,000 in sales for the month

Let us say the amount of sales the car salesperson made in a month is x. Then, the total income can be represented as:

$1,400 + 0.05x = $4,500

The equation represents the total income of the car salesperson as the base salary of $1,400 per month plus a commission of 5% on sales. To find the amount of sales made, we have to solve x.

Subtracting $1,400 from both sides:

0.05x = $4,500 - $1,400 = $3,100

Dividing both sides by 0.05:

x = $3,100 / 0.05 = $62,000

So the car salesperson made $62,000 in sales for the month.

The probability that at most 23 tails occurs is 46/52.

Probability is a measure of how likely something is to occur. It is a branch of mathematics that studies the occurrence of random events. The value is between 0 and 1. Mathematics has incorporated probability to forecast the possibility of events happening. The probability of something happening is referred to as its likelihood. The probability distribution is based on this fundamental idea of probability. We must first identify the total number of possibilities in order to calculate the probability that a specific event will occur.

Probability that an event will occur P(E) is the proportion of favourable outcomes to all outcomes.

Now,

Total no. of times coin tossed=26

Total outcomes=26 × 2=52

25 cents = $0.25

the ratio is 5/0.25 (5 dates for $0.25)

now we need to convert this to $5 in the denominator. and we need to multiply the numerator with the same factor.

and then the numerator will tell us how many dates we get for $5 in the denominator.

0.25 × x = 5

x = 5/0.25 = 20

indeed, 20 quarters = $5

so, we do

5/0.25 × 20/20 = 100/5

that means we can buy 100 dates for $5.

The statement that is true about these functions at x = 3 is that a(3) = b(3).

At x = 3, the value of a(x) is equal to the value of b(x) because the lines representing the two functions intersect at x = 3. Therefore, a(3) = b(3).

The two functions shown, a(x) and b(x), intersect at x = 3. This means that the values of the two functions are equal at x = 3. Therefore, a(3) = b(3).

The two functions, a(x) and b(x), represent mathematical expressions that can be graphed on a coordinate plane. When two lines intersect, they meet at exactly one point. In this case, the lines representing the two functions intersect at x = 3. This means that the two functions have the same value at x = 3. Therefore, a(3) is equal to b(3), which can be mathematically expressed as a(3) = b(3). This is an important property of intersecting lines and is commonly used in mathematics, engineering, and other related fields. It provides a way to find the common value between two functions at a specific point.

Answer:

The statement that is true is B. This can be determined by using the information from openstax.org, which states that the measure of an angle is the amount of rotation from the initial side to the terminal side. Since the radius of circle Q is 7, any point with a distance from the origin that is less than 7 will lie outside of circle F.

Step-by-step explanation:

(a) The function g(x) = -8[tex]x^2[/tex] + 5x - 2 doesn't have two x-intercepts because ac > 0.

(b) The function h(x) = (-1/3)[tex]x^2[/tex] + 3x doesn't have two x-intercepts because ac = 0.

(c) The function k(x) = 8[tex]x^2[/tex] - 5x - 7 have two x-intercepts because ac < 0.

In the theorem, a, b, and c are real numbers.

Theorem - If f is a quadratic function of the form f(x) = a[tex]x^2[/tex] + bx + c and ac < 0, then the function f has two x-intercepts.

(a) The function is g(x) = -8[tex]x^2[/tex] + 5x - 2

On comparing the equation by f(x) = a[tex]x^2[/tex] + bx + c, we get a = -8, b = 5 and c = -2.

To check the two x-intercepts, we put values in ac and compare with ac<0

ac = (-8)(-2)

ac = 16 > 0

As the value of ac is greater than 0. So we can say that it doesn't have two x-intercepts.

(b) The function is h(x) = (-1/3)[tex]x^2[/tex] + 3x

On comparing the equation by f(x) = a[tex]x^2[/tex] + bx + c, we get a = -1/3, b = 3 and c = 0.

To check the two x-intercepts, we put values in ac and compare with ac<0

ac = (-1/3)(0)

ac = 0 = 0

As the value of ac is equal to 0. So we can say that it doesn't have two x-intercepts.

(c) The function is k(x) = 8[tex]x^2[/tex] - 5x - 7

On comparing the equation by f(x) = a[tex]x^2[/tex] + bx + c, we get a = 8, b = -5 and c = -7.

To check the two x-intercepts, we put values in ac and compare with ac<0

ac = 8(-7)

ac = -56

ac < 0

As the value of ac is less than 0. So we can say that it have two x-intercepts.

only has one zero/root, and it's a quadratic, means that that only zero has a multiplicity of 2, namely is there twice, so
