Answer:

f(-6) = -9

Step-by-step explanation:

here, you substitute -6 for x in the function

f(x) = 3x + 9

f(-6) = 3(-6) + 9

f(-6) = -18 + 9

f(-6) = -9

Select the correct answer.

GREYUIT [131]

Answer:

Hello. The answer is A.

Step-by-step explanation:

The number before x shows the slope.

The other number shows the y intercept.

<h3>It is important that the number before y should be one and the equation should be like this:</h3>

$y = mx + h$

Here h is intercept and m is slope.

I hope you understand.

A square pyramid has a height of 6 units and a volume of 70 units3. If a square prism has the same base area and volume as the s

Svetach [21]

Answer:

The height of the prism is $h=2\ units$

Step-by-step explanation:

step 1

Find the area of the base of the pyramid

The volume of the pyramid is equal to

$V=\frac{1}{3}Bh$

where

B is the area of the base of pyramid

h is the height of the pyramid

we have

$V=70\ units^{3}$

$h=6\ units^{3}$

substitute and solve for B

$70=\frac{1}{3}B(6)$

$70=2B$

$B=35\ units^{2}$

step 2

Find the height of the prism

The volume of the prism is equal to

$V=Bh$

where

B is the area of the base of prism

h is the height of the prism

we have

$V=70\ units^{3}$

$B=35\ units^{2}$

substitute and solve for h

$70=35h$

$h=2\ units$

a random sample of 4 claims are selected from a lot of 12 that has 3 nonconforming units. using the hypergeometric distribution

Sloan [31]

Answer:

The probability that the sample will contain exactly 0 nonconforming units is P=0.25.

The probability that the sample will contain exactly 1 nonconforming units is P=0.51.

Step-by-step explanation:

We have a sample of size n=4, taken out of a lot of N=12 units, where K=3 are non-conforming units.

We can write the probability mass function as:

$P(x=k)=\frac{\binom{K}{k}\binom{N-K}{n-k}}{\binom{N}{n}}$

where k is the number of non-conforming units on the sample of n=4.

We can calculate the probability of getting no non-conforming units (k=0) as:

$P(x=0)=\frac{\binom{3}{0}\binom{9}{4}}{\binom{12}{4}}=\frac{1*126}{495}=\frac{126}{495} = 0.25$

We can calculate the probability of getting one non-conforming units (k=1) as:

$P(x=1)=\frac{\binom{3}{1}\binom{9}{3}}{\binom{12}{4}}=\frac{3*84}{495}=\frac{252}{495} = 0.51$
