Answer:

V = 803.8 cm^3

Step-by-step explanation:

h = 12cm

r = 8cm

V = $\frac{1}{3}$ $\pi$ $r^{2}$ h

V = $\frac{1}{3}$ $\pi$ $(8)^{2}$ (12)

V = 4 $\pi$ (64)

V = 803.84

Answer:

800

Step-by-step explanation:

$V=\pi r^{2} \frac{h}{3}$

$V=\pi 8^{2} \frac{12}{3} \\V=\pi (64)(4) = 256\pi$

256π = 804.247719319

To the nearest tenth: 800

A whole number n which when divided by 4 gives 3 as remainder. What will be the remainder when 2n is divided by 4?.

jeyben [28]

When 2n is divided by 4 the remainder will be 2

Division is a simple operation in which a number is divided.

Given,

A whole number n which when divided by 4 gives 3 as remainder

We know,

Dividend = (Divisor × quotient)+ Remainder

Here,

Dividend = n

Quotient = 4

Remainder =3

Consider the divisor as a

Then,

n = 4a+3

Multiply both side by 2

2n= 2(4a+3)

2n= 8a+6

Split the term 6 and take common outside

2n= 8a+4+2

2n= 4(2a+1)+2

So, when 2n is divided by 4

Divisor = 2a+1

Remainder = 2

Hence, when 2n is divided by 4 the remainder will be 2

A professor at a local university noted that the exam grades of her students were normally distributed with a mean of 73 and a s

jasenka [17]

Answer:

The minimum score of those who received C's is 67.39.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu = 73, \sigma = 11$
