Answer:

Step-by-step explanation:

If diameter is 6 then the radius is half of that or 3.

A = pi * r^2

A = pi * 3^2

A = 9pi ft^2

According to the American Community Survey, 27% of residents of the United States 25 years old or older had earned a bachelor de
oksian1 [2.3K]

a. The reason why this question is a binomial experiment is based on the fact that it is made up of an independent sample, it has a number that is fixed and a probability.

Each event is made up of two outcomes and they are random with the same success rate.

<h3>b. How to solve probability that exactly 5 had a bachelor</h3>

we have the following data n = 12, p = 0.27 and k = 5

We have to use the function to solve electronically

binompdf(n,p,k)

input the values

= binompdf(12,0.27,5)

This gives us

= 0.1255

<h3>(C) Probability that fewer than 5 have bachelor</h3>

We use the formula below

= binompdf(12,0.27,5-1)

This is = 0.7984

D. Probability of at least 5

1 - probability of fewer than 5

= 1 - 0.7984

= 0.2016

How to solve for the Mean = n*p

n = 12 , p = 0.27

Mean = 12*0.27 = 3.24

and

standard deviation = √npq

n = 12, p = 0.27 , q = 1- 0.27

= 0.73

sd = √12*.27*.73

= 1.54

Choose the graph below that represents the solution to the system of equations
nasty-shy [4]

Answer:

<h2>The solution is (1, 5)</h2>

Step-by-step explanation:

Here two equation of straight lines are given.

Two equations can intersect each other at a point.

The given equations are,

  1. y = 3x + 2
  2. 10x + 2y = 20\\ 5x + y = 10\\y = 10 - 5x

Equating both 1 and 2 we get,

10 - 5x = 3x + 2\\8x = 8\\x = 1

Hence, from 1 we get, y = 3+2 = 5

There are 32 point guards and 50 posts In Leo's basketball league. Leo must include all players on a team and wants each team to
Fantom [35]

The greatest number of teams Leo can create is 2

<em><u>Solution:</u></em>

Given that,

There are 32 point guards and 50 posts In Leo's basketball league

From given,

Number of point guards = 32

Number of posts = 50

Leo must include all players on a team and wants each team to have the same number of point guards and the same number of posts

To find the greatest number of teams Leo can create, we should find the greatest common factor of 32 and 50

When we find all the factors of two or more numbers, and some factors are the same, then the largest of those common factors is the Greatest Common Factor

<em><u>Greatest Common Factor of 32 and 50:</u></em>

The factors of 32 are: 1, 2, 4, 8, 16, 32

The factors of 50 are: 1, 2, 5, 10, 25, 50

Then the greatest common factor is 2

Thus the greatest number of teams Leo can create is 2

Mr Wallace took 600mg of medicine. This was 75% of the full dose. What was the full dose?
Aleonysh [2.5K]
Set up a proportion.

75% = 0.75

600/0.75 = x/1

Cross multiply:

0.75x = 600

Divide 0.75 to both sides:

x = 800

So the full does is 800mg.
