Answer:

Volume = 18 * pi in^3   OR IF pi=3.14 THEN   Volume = 56.52 in^3

Step-by-step explanation:

Volume = Area(circle) * Height

Volume = pi*(diameter/2)^2 *Height

Volume = pi* 2.25 * 8

Volume = 18 * pi in^3

And if pi=3.14 then:

Volume = 56.52 in^3

Answer:

V= 18 \pi

Step-by-step explanation:

V=πr²h

The radius is half of the diameter

so the radius is 3/2

r= 1.5 in

Now plug in

V= \pi 1.5²(8 in)

V= 18 \pi

I need help on question number 12. Can anybody help me? It's very urgent
Luda [366]
Number of customers = 300
Number of customers that are male and has an open-toe shoes = 11
P(male and open-toe) = 11/300

Number of customers that are male = 139 + 11 = 150
Number of customers that are male and has an open-toe shoes = 11
Given that the customer is male, 
P(open-toe) = 11/150

No, the two probabilities are not the same. The first probability has 2 variables - the gender and the shoe-type. The second probability has only 1 variable - the shoe-type

Sedaia [141]

Answer:

a) -2 degrees celsius

b) -5<-2

C) There would be an open dot on -2 and the line would go till the right end of the graph.

Step-by-step explanation:

a)-2 is warmer because -2 is a higher number than -5

b) -5 is less than -2

c) Every number above -2 on the graph is warmer than -2 so the line continues from -2 to then end.

Hope this helped:) maybe I could get brainliest?

What is the slope of the line that contains these points?
kati45 [8]

Answer:

m=-7

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS

<u>Algebra I</u>

  • Slope Formula: m=\frac{y_2-y_1}{x_2-x_1}

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Find points from chart.</em>

Point (39, 36)

Point (40, 29)

<u>Step 2: Find slope </u><em><u>m</u></em>

  1. Substitute:                    m=\frac{29-36}{40-39}
  2. Subtract:                       m=\frac{-7}{1}
  3. Divide:                          m=-7

A study was conducted to investigate the relationship between maternal smoking during pregnancy and the presence of congenital m
Pachacha [2.7K]

Answer:

a) In the explanation.

b) P=0.09714

c) P=0.0866

d) p=0.208

Step-by-step explanation:

a) The sampling distribution will have this properties:

1 - The sampling distribution of a proportion is equal to the binomial distribution.

2 - The mean of the sampling distribution will be equal to the proportion of the population (0.328).

\mu=\pi=0.328

3 - The standard deviation will be equal to the square root of the product of the proportion and its complementary, divided by the sample size.

\sigma_s=\sqrt{\pi(1-\pi)/n}=\sqrt{0.328*(1-0.328)/25}=0.094

B) The fraction with sample proportion of 0.45 or higher is

z=(p-\pi)/\sigma=(0.45-0.328)/0.094=1.298\\\\P(p\geq0.45)=P(z\geq 1.298)=0.09714

C) The fraction with sample proportion of 0.20 or lower is

z=(p-\pi)/\sigma=(0.2-0.328)/0.094=-1.362\\\\P(p\leq0.2)=P(z\geq -1.362)=0.0866

D) The value of p that cuts off the lower 10% of the distribution corresponds to z=-1.28.

Then we have

z=(p-\pi)/\sigma\\\\p=\pi+z\sigma=0.328+(-1.28)*0.094=0.328-0.120=0.208
