Answer:

(a) 0.6

(b) 0.4

Step-by-step explanation:

If I am reading the little table right, You have made 9 shots, and have missed 6 of them. Therefore, in total, you have made $9+6=15$ shots.

The definition of probability is the number of events of a desired outcome divided by the total number of outcomes. Since you wish to make a shot for part a, the number of desired outcomes thus far is 9, out of 15 total shots. Thus,

$P($ making a shot $)=\frac{9}{15}=\frac{3}{5}=0.6$

Since making a shot and not making a shot are mutually exclusive events, and the only two events that could occur when shooting a basket, the probability of not making a shot and the probability of making a shot are all of the possible outcomes, and is thus equal to 1.

$P($ making a shot $)+P($ missing a shot) $=1$

$P($ missing a shot $)=1-P($ making a shot $)$

$P($ missing a shot $)=1-0.6=0.4$

A man 50 years old has 8 sons born of equal intervals. The sum of the ages of the father and sons is 186. What is the age of the

Rudiy27

let x be the interval, then: 186 = 50 + 3 + (3+x) + (3+2x) + (3+3x) + (3+4x) + (3+5x) + (3+6x) + (3+7x) 186 = 74 + 28x x = 4 Eldest son age = 3+7x = 3+28 = 31.

A cylinder has a height of 10 inches and a radius of 17 inches. What is its volume? Use ≈ 3.14 and round your answer to the ne

Gelneren [198K]

Steps:

Radius= 17in

Height= 10in

Formula: V=πr2h

Shape: Right cylinder

Solved for volume

H= Height

R= Radius

Description:

We know that R is 17 inches, and H is 10 inches. Since we are finding the volume we use the formula V=πr2h to calculate. After calculating your answer will come as V≈9079.2in³. You also said to round your answer to the nearest hundredth. After rounding your answer to th enearest hundredth your answer will come as 9,079.20.

Answer: V≈9079.2in³

Round to the nearest hundredth = 9,079.20

How do I do this problem?

Sedaia [141]

Use the reciprocal method. the first term is really 4 divided by 3/4. which is also the same as 4 multiplied by 4/3. that number is 16/3 of course. you then find a common denominator between the 2 terms. 16/3 and 3/2 can both have the denominator 6. The first term gets changed to 32/6 and the second can be changed to 9/6 and when 32/6 - 9/6 is done, it comes out to 23/6

23/6
