Answer/Step-by-step explanation:
Volume of a sphere = ⁴/3πr³
1. r = ½ of 14.4 = 7.2 in.
Volume = ⁴/3 × π × 7.2³ = 1563.46 ≈ 1563.5 in.³
2. r = 6 yd
Volume = ⁴/3 × π × 6³ = 904.78 ≈ 904.8 yd³
3. r = 8 mm
Volume = ⁴/3 × π × 8³ = 2144.66 ≈ 2144.7 mm³
4. r = ½ of 13.5 = 6.75 cm
Volume = ⁴/3 × π × 6.75³ = 1288.25 ≈ 1288.3 cm³
5. r = 4.7 in.
Volume = ⁴/3 × π × 4.7³ = 434.89 ≈ 434.9 in.³ (nearest tenth)

A television station shows 3 commercials every 12 minutes. At this rate, how many commercials will the station show in 84 minutes?
Answers
Answer:
21
Step-by-step explanation:
84/12=7x3=21
It will take 72 mins to see 18 commercials.
Step-by-step explanation:
If a television station shows commercials every 12 mins, then to figure out how long it takes to see 18 commercials you will have to do 18 / 3 which is 6. Then do 12 * 6 and you will get 72 mins.
Another method is finding the unit rate of how long does it take to see one commercial. So in order to do that, you will have to do 12 / 3, and you will get 4. So, to see one commercial it will take 4 mins. But you want to find how long will it take to see 18 commercials. So you do 18 * 4 which equals 72 mins.

What is the surface area of a sphere?The area of the outer surface of a sphere is the surface area of a sphere.
And its formula:
The surface area of the sphere is 4πr².
Where r is the radius of the sphere.
Given:
The shape of the basketball is spherical.
The diameter of the basketball is 10 inches.
So, the radius of the basketball = 10/2 = 5 inches.
The surface area of the basketball,
= the surface area of the sphere.
= 4πr²
= 4π(5)²

A camp director developed the function m(c) = 12c + 80 to model the total cost of taking c campers on a field trip to the movies.
In the camp director’s function, the number of campers is the _______ variable and the total cost of the trip _________
1. ( independent, dependent )
2. ( changes by a constant factor per camper, Changes by a constant amount per camper )
.
Answers
Answer:
(a) Independent variable
(b) The constant factor is 12
Step-by-step explanation:
Given
[tex]m(c) = 12c + 80[/tex]
c = campers
m = total cost
Solving (a) What type of variable is the number of campers (c)
The total cost (m) is dependent on the number of campers (c) for its own value.
In other words, if c changes from 5 to say 7, the value of m will also change.
This implies that the number of campers is an Independent variable
Solving (b): Constant factor
This in other words means, rate of change (or slope)
A linear function is:
[tex]y = ax + b[/tex]
Where a represents the slope
By comparison with: [tex]m(c) = 12c + 80[/tex]
Hence, the constant factor is 12
Answer:
dependent, changes by a constant factor per camper.

6. If a person adopts a pet, it's either a cat or a dog. 25% of the time, it's a cat and 75% of the time, it's a dog. If you meet someone at the shelter that adopted three pets, what's the probability that they got either: three cats or three dogs? Show your calculation and give your single answer as a decimal.
Answers
Answer:
0.0156 probability that they got three cats.
0.4219 probability that they got three dogs.
Step-by-step explanation:
For each person there are only two possible outcomes. Either they adopted a dog, or a cat. The probability of a person adopting a cat or a dog is independent of any other person, which means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
Three people:
This means that [tex]n = 3[/tex]
What's the probability that they got three cats?
25% of the time it's a cat adopted, which means that [tex]p = 0.25[/tex]
This is P(X = 3). So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 3) = C_{3,3}.(0.25)^{3}.(0.75)^{0} = 0.0156[/tex]
0.0156 probability that they got three cats.
What's the probability that they got three dogs?
75% of the time it's a dog adopted, which means that [tex]p = 0.75[/tex]
This is P(X = 3). So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 3) = C_{3,3}.(0.75)^{3}.(0.25)^{0} = 0.4219[/tex]
0.4219 probability that they got three dogs.
