Answer:

605.5

Step-by-step explanation:

When you do a frequency table for this question,the zigma F becomes 2 and the zigma fx becomes 1211.Because you will multiply the marks by the frequency to get the zigma fx so after getting them you add it.Which becomes 403+808=1211.the formula for finding the mean too is zigma fx/zigma f: 1211/2=605.5

A group of artists is selling small prints to raise money for charity. They sell p prints, and make a profit of f(p) on the sale

MrRissso [65]

Answer:

Statement A is true.

Step-by-step explanation:

A. If the group sells 15 prints, they will lose $85.

B. If the group sells 12 prints, they will lose $204.

C. If the group sells 35 prints, they will make $935.

D. If the group sells 28 prints, they will lose $136.

f(p) = 17p - 340

p = prints

f(p) = profit

Let's check the statements to see which one is true.

A. 17.15 - 340 = - 85 OK!

B. 17.12 - 340 = -136 (false, they will lose $136)

C. 17.35 - 340 = 255 (false, they will make $255)

D. 17.28 - 340 = 136 (false, they will make $136)

Type the correct answer in the box.

statuscvo [17]

Step-by-step explanation:

V should be written as (1/3) pi r^2 h

V = (1/3) pi r^2 h multiply by 3

3V = pi r^2 h Divide by pi

3V/ pi = r^2 h Divide by r^2

3V / (pi *r^2 ) = h

Renna pushes the elevator button, but the elevator does not move. The mass limit for the elevator is 450 kg, but Renna and her l

pychu [463]

Answer:

$620-37.4p\leq 450$

Step-by-step explanation:

Let p be the number of identical packages.

We have been given that each package has a mass of 37.4 kg, so weight of p packages will be 37.4p.

The total mass of Renna and her load of identical packages is 620 kg.

We have been given that the mass limit for the elevator is 450 kg. This means that Renna can remove p packages from 620 kg such that 620 minus weight of p packages will be less than or equal to 450 kg.

We can represent this information in an inequality as:

$620-37.4p\leq 450$

Therefore, the inequality $620-37.4p\leq 450$ can be used to determine the number of packages, p, Renna could remove from the elevator to meet the mass requirement.
