$f(x)=x^2-5\\\\g(x)=9x-2\\\\\\f(g(x))=\big(9x-2\big)^2-5=81x^2-2\cdot9x\cdot2+4-5=\boxed{81x^2-36x-1}$

Emichee can you help me? A cylinder has a base with a radius of 8 inches and a height of 15 inches. What is the volume of the cy

Lina20 [59]

The volume of a Cylinder is:

$V=A_b*h$

the base is a circle, so

$A_b=\pi*r^2$

replacing

$V=\pi*r^2*h$

now we have the values

$V=3.14*8^2*15$

$\boxed{\boxed{V=3014.4~in^3}}$

Which data set has the greatest spread for the middle 50% of its data?

Sindrei [870]

Answer:

The answer is (c) {13, 17, 12, 21, 18, 20}.

Step-by-step explanation:

The given data sets are:

{18, 13, 22, 17, 21, 24},

{17, 19, 22, 26, 17, 14},

{13, 17, 12, 21, 18, 20}

and

{18, 21, 16, 22, 24, 15}.

To find the greatest spread for the middle 50%, we need to find the Interquartile range for all the data sets and check which one is highest.

For first set, Interquartile range (IQR) = 22 - 17 = 5.

For second set, IQR = 22 - 17 = 5.

For third set, IQR = 20 - 13 = 7

and

for fourth set, IQR = 22 - 16 = 6.

Since IQR is highest for the third data, so the correct option is (c) {13, 17, 12, 21, 18, 20}.

Hope it helps
