The mean of a binomial probability distribution is given by μ = np where n is the number of trials (number of samples) and p is the probability of success.

Given that a<span> statistics class at wilmington college has 25 students of which 15 are math majors and 10 are business majors and selecting a business major is defined as a success.

p = 10 / 25 = 0.4

If the professor randomly selects five students to work together on a group project, the mean of this probability distribution is given by 5 x 0.4 = 2.</span>

A pharmacist is filling small empty bottles with cough syrup from a larger bottle. He can solve the inequality
goldfiish [28.3K]

If a pharmacist is filling small empty bottles with cough syrup from a larger bottle. The statement that  describes the number of small bottles the pharmacist can fill is: A. The pharmacist can fill 30 bottles or fewer.

<h3>Number of small bottles the pharmacist can fill</h3>

Given:

inequality=1,000-25x ≥250

Let x represent the number of small bottles

Hence:

1,000-25x ≥250

Collect like terms

1,000-250 ≥25x

750 ≥25x

Divide both side by 25x

x=750/25

x=≤30 bottles or fewer


Therefore If a pharmacist is filling small empty bottles with cough syrup from a larger bottle. The statement that  describes the number of small bottles the pharmacist can fill is: A. The pharmacist can fill 30 bottles or fewer.

Write the point-slope form of the equation of the line passing through the points (-5, 6) and (0, 1).
Y_Kistochka [10]
The point slope form:
y - y_1 = m(x - x_1)

We need to find the slope. To find the slope we can use the following formula:
\frac{y_2 - y_1}{x_2 - X_1}

Use the points <span>(-5, 6) and (0, 1) and plug it into our slope formula and solve:
</span>\frac{1 - 6}{0 - (-5)}
\frac{-5}{5} = -1

So our slope is -1 which means m = slope = -1 
Now that we have our slope lets create the point slope form

Our point slope form equation is y - y_1 = m(x - x_1) Remember 
m = slope = -1. Also, we are going to use the point (-5,6).

First insert the m = slope = -1 number where m is located
y - y_1 = -1(x - x_1)

Next, insert the -5 from (-5,6) where x_1 is located and the 6 from (-5,6) where y_1 is located.
y - y_1 = -1(x - x_1)
y - 6 = -1(x - (-5))
Now simplify 
y - 6 = -1(x - (-5))
y - 6 = -1(x +5) <-------Answer

Which choice is equivalent to the quotient shown here when x is greater than or equal to 0?
Dima020 [189]

Answer: OPTION C

Step-by-step explanation:

Remember that:

\sqrt[n]{a^n}=a

And the Product of powers property establishes that:

a^m*a^n=a^{(mn)}

Rewrite the expression:

\frac{\sqrt{18x} }{\sqrt{32} }

Descompose 18 and 32 into their prime factors:

18=2*3*3=2*3^2\\32=2*2*2*2*2=2^5=2^4*2

Substitute into the expression, then:

\frac{\sqrt{(2*3^2)x} }{\sqrt{2^4*2} }

Finally,simplifying, you get:

\frac{3\sqrt{(2)x} }{2^2\sqrt{2} }=\frac{3\sqrt{2x}}{4\sqrt{2}}=\frac{(3)(\sqrt{x})(\sqrt{2})}{(4)(\sqrt{2})}= \frac{3\sqrt{x}}{4}

What will the time be after 1 hour 5 minutes from 8:15 am
umka2103 [35]

Answer:

9:20 am

Step-by-step explanation:

So, lets go over two things.

Minutes and hours.

Minutes changes the second number.

You know how when a number goes from 9 to 10 how the ones place is set to 0, and the tens place goes up? Its the same with time, only when the number goes from 59 to 60, the hour goes up.

Hours changes the hours place, and when it hits 12, it resets to 1, and the words am go to pm, or pm goes to am.

In this case. we are moving the minutes place up by 5:

15+5=20

So the minutes place is 20, and does not change the hours place since it is below 60.

Next we have a increase in hours by 2:

8+1=9

So the hours place is 9, and does not reset or change the pm/am since its below 12.

Answer:

9:20am

Hope thias helps!
