In a study of the television viewing habits of children, a developmental psychologist selects a random sample of 300 first graders - 100 boys and 200 girls. Each child is asked which of the following TV programs they like best: The Lone Ranger, Sesame Street, or the Simpsons.
Complete the following table:
Answers
Answer:
20, 50, 70, 110
Step-by-step explanation:
boys x simpsons: 20
girls x long ranger: 50
girls x simpsons: 70
total x sesame street: 110
have a great day :)
20 girls watch Long Ranger , 110 first graders watch Sesame Street , 20 boys watch Simpsons, and 70 girls watch Simpsons.
What is random sampling?" Random sampling is a process of observing samples using such technique that each sample has equal probability."
According to the question,
As per the information of random samples given in the table,
Total number of boys are = 100
Total number of girls = 200
For boys
Long Ranger + Sesame Street + Simpsons = 100
⇒ 50 + 30 + Simpsons = 100
⇒ Number of boys view Simpsons = 100 - 80
= 20
In Long ranger column,
50 Boys + ___girls = 100
⇒ Number of girls watching Long Ranger = 100 -50
= 50
In Sesame street
30 boys + 80 girls = 110 Total viewers
Number of girls watching Simpsons = 90 -20
= 70
Hence, 20 girls watch Long Ranger , 110 total boys and girls watch Sesame Street , 20 boys watch Simpsons, and 70 girls watch Simpsons.

a) $2,945
b) $3,846
ОООО
c) $4,012
d) $4,333
Answers
Answer:b) $3,846
Step-by-step explanation:
If your third month's revenue is estimated at $5,000, then $3846.15 is second month's revenue.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given that business's revenue will grow at a compounded rate of 30% each month for the first 6 months.
Third month's revenue is estimated at $5,000.
We need to find the second month's revenue.
Let us assume the revenue of second month = x
Compounded rate = 30%
x + 30% of x = 5000
x + 0.3x = 5000
1.3x = 5000
Divide both sides by 1.3
x = 3846.15
Hence, $3846.15 is second month's revenue.

There are 15 tiles in total. Three of them are yellow and four of them are green.
You add 3+4, and get 7. You put 7 over the total amount of tiles in the bag, which leads to 7/15.
Answer:
7/15
Step-by-step
The total amount of tiles is 15, then the total number of green and yellow tiles is 4 +3 = 7. Which means that the probability that you will get green or yellow tiles is the toltal amount of tiles of green and yellow tiles combined which is 7, compared to the total number of all tiles which is 15

A basketball player stands near the middle of the court and throws the ball toward the basket.
The path of the ball is a parabola. The ball leaves the player's hands at a height of 6 feet above the ground. The
ball travels to a maximum height of 12 feet when it is a horizontal distance of 18 feet from the player's hands.
Write a function to represent the height of the ball in terms of its distance from the player's hands?
Answers
Answer:
A function to represent the height of the ball in terms of its distance from the player's hands is [tex]y=\frac{-1}{54}(x-18)^2+12[/tex]
Step-by-step explanation:
General equation of parabola in vertex form [tex]y= a(x-h)^2+k[/tex]
y represents the height
x represents horizontal distance
(h,k) is the coordinates of vertex of parabola
We are given that The ball travels to a maximum height of 12 feet when it is a horizontal distance of 18 feet from the player's hands.
So,(h,k)=(18,12)
Substitute the value in equation
[tex]y=a(x-18)^2+12[/tex] ---1
The ball leaves the player's hands at a height of 6 feet above the ground and the distance at this time is 0
So, y = 6
So,[tex]6=a(0-18)^2+12[/tex]
6=324a+12
-6=324a
[tex]\frac{-6}{324}=a[/tex]
[tex]\frac{-1}{54}=a[/tex]
Substitute the value in 1
So,[tex]y=\frac{-1}{54}(x-18)^2+12[/tex]
Hence a function to represent the height of the ball in terms of its distance from the player's hands is [tex]y=\frac{-1}{54}(x-18)^2+12[/tex]
