The spinner below shows 10 equally sized slices. Charmaine spun the dial 40 times and got the following results.
Outcome Grey White Black
Number of Spins 25 9 6
Fill in the table below. Round your answers to the nearest thousandth.
(a) From Charmaine's results, compute the experimental probability of landing on white.
(b) Assuming that the spinner is fair, compute the theoretical probability of landing on white.
(c) Assuming that the spinner is fair, choose the statement below that is true:
1. The experimental and theoretical probabilities must always be equal.
2. As the number of spins increases, we expect the experimental and theoretical probabilities to become closer, though they might not be equal.
3. As the number of spins increases, we expect the experimental and theoretical probabilities to become farther apart.
Answer:
9/40= 0.225 (experimental probability for white)
(b) because the spinner has 10 sections but there has only been 3 outcomes. If the spinner has 3 sections the changes of white would be 0.333.
2. Is correct, the more times you spin the closer you’ll get to the theoretical probability.

A patio tile design is constructed from a square inscribed in a circle. The circle has radius 6 square 2 feet.
Answer:
Step-by-step explanation:
The edge of the square is 12 feet. Then the area of the square is 144 square feet.
What is the area of the square?All the sides of a square are congruent. Let a be the side length of the square. Then the area of the square is the square of the side length of the square.
Then the area of the square will be
Area of the square = a² square units
A porch tile configuration is developed from a square engraved all around. The circle has a span of 6√2 feet.
The edge of the square is calculated as,
(2r)² = a² + a²
2r² = a²
2 × (6√2)² = a²
2 × 36 × 2 = a²
a² = 144
a = 12 feet
Then the area of the square is calculated as,
A = (12)²
A = 144
The edge of the square is 12 feet. Then the area of the square is 144 square feet.
More about the area of the square link is given below.

Complete question :
Dusty won $125,000 on the Who Wants to be a Zillionaire? game show. He decides to place the money into an account that earns 6.25% interest compounded annually and plans not to use any of it until he retires. a. Write an equation that represents the amount of money Dusty will have in n years. b. How much money will be in the account when he retires in 23 years?
Answer:
A = 125000(1.0625)^n ;
$504052.30
Step-by-step explanation:
Going by the compound interest formula :
A = P(1 + r/n)^nt
Here, P = amount won ; A = final amount ; r = interest rate = 6.25% = 0.0625 ; n = 1 ; t = number of years
Hence, the amojt of money, A Dusty will. Have in n years ;
A = 125000(1 + 0.0625)^n
A = 125000(1.0625)^n
Amount he'll have in 23 years
n = 23
A = 125000(1.0625)^23
A = 125000 * 4.03241
A = $504052.30

At a children's show, 2/7 of the people attending were adults.The rest were children.2/5 of the children were boys.There were 120 girls attending the performance. A.How many children were there at the children's show?B.How many people were there at the children's show?
Answer:
A. 200 Children
B. 280 People
Step-by-step explanation:
Let the total number of people attending the show be Y
Given that 2/7 of the people attending were adults, the number of adults A
A = 2/7 Y
Since the rest were children, the number of children C
C = Y - 2/7 Y
= 5/7 Y
2/5 of the children were boys, the number of boys B
B = 2/5 * 5/7Y
= 2/7 Y
The number of Girls G
G = 5/7 Y - 2/7 Y
= 3/7 Y
Given that there were 120 girls attending the performance
3/7 Y = 120
3Y = 120 * 7
Y = 120 * 7/3
= 280
The number of children in the shown C
= 5/7 * 280
= 200
The number of people at the show is Y = 280

A population of bacteria grows according to the function p(t) = po · 1.42, where t is measured in hours. If
the initial population size was 1,000 cells, approximately hoy long will the it take the population to exceed 10,000
cells? Round your answer to the nearest tenth.
Answer:
The time duration for the population to exceed 10,000 is approximately 6.6 hours
Step-by-step explanation:
The given equation for the population of a bacteria is presented as follows;
[tex]p(t) = P_0 \cdot 1.42^t[/tex]
Where;
t = The time duration in hours
The initial population of the cells = 1,000
Therefore, at t = 0, P(0) = 1,000 = P₀ × 1.42^0
∴ P(0) = 1,000 = P₀ × 1 = P₀
P₀ = 1,000
When the population is 10,000, we have;
P(t) = 10,000 = 1,000 × 1.42^t
∴ 1.42^t = 10,000/1,000 = 10
㏒(1.42^t) = ㏒(10) = 1
∴ t × ㏒(1.42) = 1
t = 1/㏒(1.42) = 6.56649071898
∴ The time duration for the population to exceed 10,000, t ≈ 6.6 hours.
What will your balance be on an investment of $1,000 at 4.% for 5 years compounded annually.
