Answer:

942.48

Step-by-step explanation:

use the formula v=bh

step 1:find base use the formula to find the area of the circle

step 2:then multiply your answer of base with your height

like this $\pi5^{2}$ then 78.59(12)

Professor Halen has 184 students in his college mathematics lecture class. The scores on the midterm exam are normally distribut

AURORKA [14]

Answer: 21

Step-by-step explanation:

Given : The scores on the midterm exam are normally distributed with

$\mu=72.3\\\\\sigma=8.9$

Let X be random variable that represents the score of the students.

z-score: $z=\dfrac{x-\mu}{\sigma}$

For x=82

$z=\dfrac{82-72.3}{8.9}\approx1.09$

For x=90

$z=\dfrac{90-72.3}{8.9}\approx1.99$

Now, the probability of the students in the class receive a score between 82 and 90 ( by using standard normal distribution table ) :-

$P(82$

Now ,the number of students expected to receive a score between 82 and 90 are :-

$184\times0.1146=21.0864\approx21$

Hence, 21 students are expected to receive a score between 82 and 90 .

Chris Johnson ran the 40- yard dash in 4.24 seconds. What is the rate of speed? Round any answer to the nearest hundredth

sineoko [7]

Distance divided by time is speed. To find the rate of speed, divide 40 yards by 4.24 seconds which is approximately 9.43 yards per second. 9.43 yards per second is the rate of speed.

Evaluate the polynomial for the given value of x: f(x) =3x^3+5x^2+x-2 when x=2

sasho [114]

Answer: $f(2)=44$

Step-by-step explanation:

Given the polynomial $f(x) =3x^3+5x^2+x-2$ , you can evaluate it for the given value of the variable "x" by substituting the value $x=2$ into the polynomial.

Therefore, when $x=2$ , you get the following result:

$f(x) =3x^3+5x^2+x-2 \\\\f(2) =3(2)^3+5(2)^2+(2)-2\\\\f(2)=3(8)+5(4)+2-2\\\\f(2)=24+20\\\\f(2)=44$
