Answer: 20.7

Step-by-step explanation:

Step 1. Ok, to round to the nearest 10th means to round to the nearest 10th place on the decimal side of the of the number.

Step 2. The 10th place in this decimal 10.73 is where the 7 is.

Step 3. If the 100th place is less than 5 you round down. Since, the hundredth place in this decimal is where the 3 is you are going to round down.

The answer is 20.7. Hope this helps!

The number of text messages sent daily by a student is a poisson random variable with parameter λ=5 .in a class with 20 independ
Rudik [331]
This problem is a combination of the Poisson distribution and binomial distribution.

First, we need to find the probability of a single student sending less than 6 messages in a day, i.e.
P(X<6)=P(X=0)+P(X=1)+P(X=2)+P(X=3)+P(X=4)+P(X=5)
=0.006738+0.033690+0.084224+0.140374+0.175467+0.175467
= 0.615961

For ALL 20 students to send less than 6 messages, the probability is
P=C(20,20)*0.615961^20*(1-0.615961)^0
=6.18101*10^(-5)   or approximately
=0.00006181

PLEASE HELP ME AND MY FRIEND NEED THIS QUESTION ANSWERED PLEASE HELP
Bas_tet [7]

Answer:

V_{cone} =65.94\: cm^3

Step-by-step explanation:

  • Height of cone (h) = 7 cm

  • Base radius (r) = 3 cm

  • Formula for Volume of cone is given as:

  • V_{cone} = \frac{1}{3}\pi r^2h

  • Plugging the values of h and r in the above formula, we find:

  • V_{cone} = \frac{1}{3}(3.14) (3)^2(7)

  • \implies V_{cone} = \frac{1}{\cancel 3}(3.14) (\cancel 9)(7)

  • \implies V_{cone} = (3.14) (3)(7)

  • \implies V_{cone} =65.94\: cm^3

Vesnalui [34]

Answer:

Volume of right rectangular prism = 3.75 in³

Step-by-step explanation:

Given:

First side of rectangular prism = 2 inches

Second side of rectangular prism = 1\frac{1}{2} = 1.5 inches

Third side of rectangular prism = 1\frac{1}{4} = 1.25 inches

Find:

Volume of right rectangular prism:

Computation:

Volume\ of\ right\ rectangular\ prism=lbh\\\\Volume\ of\ right\ rectangular\ prism=(2)(1.5)(1.25)\\\\ Volume\ of\ right\ rectangular\ prism= 3.75 in^3

Select all the correct locations on the table.
AlladinOne [14]
Average rate of change: r=[f(b)-f(a)]/(b-a)

r=-60→[f(b)-f(a)]/(b-a)=-60

b=5; f(b)=-213; a=1; f(a)=27
(-213-27)/(5-1)=(-240)/4=-60

Answer: The <span>two points in the table which create an interval with an average rate of change of -60 are:
x     f(x)
1      27
5   -213</span>

Answer:

The surface area of the cylinder is about 954.56 square inches.

Step-by-step explanation:

The total surface area of a cylinder is given by the formula:

SA=2\pi r^2 + 2\pi rh

Here, we are given that the radius is 8 inches and that the height is 11 inches. We are also using 3.14 for π. So, substitute:

SA\approx 2(3.14)(8)^2+2(3.14)(8)(11)

Use a calculator:

SA\approx 954.56\text{ in}^2

The surface area of the cylinder is about 954.56 square inches.
