a basketball player makes 80% of her free throws. what is the standard deviation of the successes from 100 free throws?

Answers

Since 80 out of 100 free throws were successful, the standard deviation of the success rate would be 8, and the standard deviation of a binomial distribution is the square root of (p*q)/n, where p is the probability of success, q is the probability of failure (1-p), and n is the total number of trials.

Standard deviation is calculated as follows:

p*q/n = 0.8*0.2/100 = 0.0016 = 0.04 = 8

Since 80% of 100 equals 80 successful free throws, the standard deviation of the successes from 100 free throws would be 8. The dispersion in a set of data is measured by standard deviation. A binomial distribution's standard deviation is equal to the square root of (p*q)/n, where p is the success probability, q is the failure probability (1-p), and n is the number of trials. Since the success rate in this instance is 80%, p = 0.8, q = 0.2, and n = 100. The standard deviation is then equal to the square root of (p*q/n): (0.8*0.2/100) = (0.0016) = (0.04), which equals 8. Therefore, the standard deviation of the successes from 100 free throws for a basketball player who makes 80% of them would be 8.

Answers

The  product of prime polynomials which is equivalent to 30x3 – 5x2 – 60x is option C) 5x(2x – 3)(3x + 4).

We have 30x³ - 5x² - 60x

We take common value out so

5x(6x² - x - 12)

By following the factorization method we get,

6x² - x - 12

b²-4ac = -1² - 4x6x(-12)

= 289

x = -b ± √289/2a

= 1 ± 17/-2

x = 3/2 or x = -4/3

So,

6x² - x - 12

6(x-3/2)(x-(-4/3))

(2x-3) (3x+4)

Therefore,

30x³ - 5x² - 60x = 5x(6x² - x - 12)

A party will have pentagonal tables placed together. The number of people, P, who can sit at the tables is a function of the number of tables, n.

A. Explain why the equation
P=3n+2 defines this function.

B. How many tables are needed if 47 people come to the party?

C. How many tables are needed if 99 people come to the party?

D. Write the inverse of this function and explain what the inverse function tells us?

Answers

a) The number of tables increases, the number of people who can sit at the tables will increase as well, and this relationship is captured by the function.

b) 15 tables are needed for 47 people to sit at pentagonal tables placed together.

c) 33 tables are needed for 99 people to sit at pentagonal tables placed together.

d) 6 tables are needed to seat 20 people at pentagonal tables placed together.

A. The equation P=3n+2 defines this function because it tells us that the number of people who can sit at the tables is equal to three times the number of tables plus two.

B. To determine how many tables are needed if 47 people come to the party, we need to use the function P=3n+2 and solve for n. We substitute 47 for P and get:

47 = 3n + 2

45 = 3n

n = 15

C. Similarly, to determine how many tables are needed if 99 people come to the party, we substitute 99 for P and get:

99 = 3n + 2

97 = 3n

n = 32.33 ≈ 33

D. To find the inverse of the function P=3n+2, we need to solve for n in terms of P. This gives us:

P = 3n + 2

P - 2 = 3n

n = (P - 2)/3

The inverse function, denoted by f⁻¹, is then:

f⁻¹(P) = (P - 2)/3

The inverse function tells us the number of tables needed to seat a certain number of people. For example, if we want to seat 20 people, we can use the inverse function to determine how many tables are needed:

f⁻¹(20) = (20 - 2)/3

f⁻¹(20) = 6

If the problem is exact find a function F(x,y) whose differential, dF(x,y) is the left hand side of the differential equation. That is, level curves F(x,y)=C, give implicit general solutions to the differential equation.

If the equation is not exact, enter NE otherwise find F(x,y) (note you are not asked to enter CC)

F(x,y)=

Answers

The level curves of F(x,y) = C give the implicit general solutions to the differential equation.To find My and Nx, we need to rearrange the differential equation in the form of Mdx + Ndy = 0, where M and N are functions of x and y.

Starting with the given differential equation:

mdx + ndy = 0

We can plug in the values of m and n from the equation given:

(4x + 5y)dx + (5x + 5y)dy = 0

Now we can identify M and N:

M = 4x + 5y

N = 5x + 5y

Therefore:

My = dN/dy = 5

Nx = dM/dx = 4

Since My is not equal to Nx, the equation is not exact. To find the function F(x,y), we can use an integrating factor.

First, we find the integrating factor, u:

u(x) = e^(∫(My - Nx)/Nx dy) = e^(∫(5-4)/4 dy) = e^(y/4)

Multiplying both sides of the differential equation by u(x):

e^(y/4)(4x + 5y)dx + e^(y/4)(5x + 5y)dy = 0

We can rewrite this as:

d(e^(y/4)(4x + 5y)) = 0

Integrating both sides with respect to x:

e^(y/4)(4x + 5y) = F(y)

Therefore:

F(x,y) = e^(y/4)(4x + 5y)

Therefore, The level curves of F(x,y) = C give the implicit general solutions to the differential equation.

The sides of a △ are 12, 16, and 22. Find the longest side of a similar △ with perimeter 40.

Answers

To find the longest side of a similar triangle with a perimeter of 40, we need to determine the scale factor between the two triangles.

The perimeter of the original triangle is given by the sum of its three sides:

Perimeter of original triangle = 12 + 16 + 22 = 50.

Now, we can calculate the scale factor as the ratio of the perimeters:

Scale factor = (Perimeter of new triangle) / (Perimeter of original triangle) = 40 / 50 = 0.8.

To find the longest side of the similar triangle, we multiply the longest side of the original triangle by the scale factor:

Longest side of new triangle = 22 * 0.8 = 17.6.

Therefore, the longest side of the similar triangle with a perimeter of 40 is 17.6 units.

find the surface area for a sphere with a radius of 10 feet. round to the nearest whole number. a. 1,256 ft2b. 4,189 ft2c. 1,089 ft2d. 1,568 ft2

Answers

The surface area of a sphere with a radius of 10 feet is approximately 1,256 ft².

The surface area of a sphere refers to the total area that covers the surface of the sphere. It is the sum of all the areas of the small flat faces that make up the sphere.

To find the surface area of a sphere with a radius of 10 feet, we need to use the formula:

Surface Area = 4πr²

Where r is the radius of the sphere.

Plugging in the value of r=10 into the formula, we get:

Surface Area = 4π(10) = 400π

Since π is an irrational number, we cannot calculate its exact value. However, we can approximate it to 3.14. Therefore,

=> Surface Area = 400 * 3.14 = 1256

Rounding to the nearest whole number, we get the surface area of the sphere with a radius of 10 feet as 1,256 ft², which is option (a).

The original price of an item is $25, but after the discount, you only have to pay $18.50. What is the discount (as a percent)

Answers

The discount is 26%.

What is Discount?

The discount equals the difference between the price paid for and it's par value. Discount is a kind of reduction or deduction in the cost price of a product.

Given:

\(\bold{Marked} \ \text{price} = \$25\)

\(\bold{Selling} \ \text{price} = \$18.50\)

So,

\(\text{Discount = MP - SP}\)

\(\text{Discount} = 25-18.50\)

\(\bold{Discount} = 6.50\)

Now,

\(\text{D}\% = \dfrac{\text{D}}{\text{MP}} \times100\)

\(\text{D}\% = \dfrac{6.5}{25} \times100\)

\(\text{D}\% = 26\%\)

Arnold deposited $732.19 in a savings account that earns 2.7% simple interest. What is Arnold's account balance after seven years? A) Calculate the pH of 0. 215 M carbonic acid. Ka1 for carbonic acid is 4. 3 X 10-7. pH = 3. 52B) Now, suppose you add some solid sodium hydrogen carbonate to the carbonic acid solution in part A). What will happen to the pH?The pH will remain the same when the sodium hydrogen carbonate is added. You can't tell what will happen to the pH. The pH will rise when the sodium hydrogen carbonate is added. A buffer is formed and the pH will rise when the sodium hydrogen carbonate is added. The pH will fall when the sodium hydrogen carbonate is added. A buffer is formed and the pH will fall when the sodium hydrogen carbonate is added. A buffer is formed and the pH will remain the same when the sodium hydrogen carbonate is added. C) Calculate the pH of solution when the concentration of sodium hydrogen carbonate is 0. 820 M. pH = 6. 94790693688853 Assume you bulk loaded the keys 1 to 60 into a b tree with fill-factor. 75 and order d = 2.
