Answer:
70
You got it correct :)
Step-by-step explanation:
[tex]\frac{28}{y} =\frac{40}{100}[/tex]
y × 40 = 100 × 28
40y = 2800
40y ÷ 40 = 2800 ÷ 40
y = 70

The Slow Ball Challenge: There will be 9 pitches, each at 60 mph. Diego estimates that he will hit each individual pitch 95% of the time. If Diego can hit all 9 pitches, he will win a total of $45; otherwise he will lose $10. The Fast Ball Challenge: There will be 4 pitches, each at 90 mph. Diego estimates that he will hit each individual pitch 60% of the time. If Diego can hit all 4 pitches, he will win a total of $80; otherwise he will lose $20. Show Proof of which challenge he should play and why?
Answer:
He should play the Slow Ball Challenge
Step-by-step explanation:
The number of pitches = 9 pitches
The speed of the 9 pitches = 60 mph
The percentage of the time Diego estimates he can each pitch = 95%
P = 0.95
The amount Diego will win if he can hit all 9 pitches = $45
The amount he will loose = $10
The Fast Ball challenge
The number of pitches = 4 pitches
The speed of the 4 pitches = 90 mph
The percentage of the time Diego estimates he can each pitch = 60%
The amount Diego will win if he can hit all 4 pitches = 60 %
The amount he will loose = $20
For the Slow Ball challenge, we have;
The probability that he hits all 9 pitches and wins the $45, is given by the binomial probability distribution as follows;
P(X) = ₙCₓ · Pˣ ·(1 - P)ⁿ⁻ˣ
Therefore, we get;
P(X) = ₉C₉ · P⁹ ·(1 - P)⁹⁻⁹ = 1 × 0.95⁹ ≈ 0.63025
The probability that he losses the $45 = 1 - P(X) ≈ 1 - 0.63 = 0.36975
The expected value = 0.63025 × 45 - 0.36975 × 10 ≈ 24.66375
The expected value ≈ 24.66375
For the Fast Ball challenge, we have;
The probability that he hits all 4 pitches and wins the $80, is given by the binomial probability distribution as follows;
P(X) = ₙCₓ · Pˣ ·(1 - P)ⁿ⁻ˣ
Therefore, we get;
P(X) = ₄C₄ · P⁴ ·(1 - P)⁴⁻⁴ = 1 × 0.6⁴ ≈ 0.1296
The probability that he losses the $80 stake = 1 - P(X) ≈ 1 - 0.1296 = 0.8704
The expected value = 0.1296 × 80 - 0.8704 × 20 ≈ -7.04
The expected value ≈ -7.04.
Given that the expected value for the Fast Ball Challenge is lesser than the expected value for the Slow Ball Challenge, Diego should play the Slow Ball Challenge.
The circumference of a circular pool is 43.96 meters. What is the area in square meters? Use 3.14 for pi.
A. 153.86
B.145.30
C.138.03
D.47.10
Answer:
The answer is letter A
Step-by-step explanation:
Area of a circle in terms of radius:
A circle of radius = 6.996 or 7, or diameter = 13.99 or circumference = 43.96 meters
Area = π · r^2 = 3.14 * 7^2 = 153.86 square meters

The formula to find the number of chairs in each row is m = . If 60 people attend the meeting and each row has 4 chairs, there are rows.
Answer:
m = x / n
n = 15
Step-by-step explanation:
Number of chairs per row = m
Number of rows = n
Number of people = x
Number of chairs per row, m = number of people, x / Number of rows, n
m = x / n
If number of attendees, x = 60 ;
Number of chairs per row, m = 4
The number of rows, n = number of attendees / number of chairs per row, m
Hence, n = 60 / 4 = 15 rows

Step-by-step explanation:
Cyrus is hosting a dinner to celebrate Nowruz,
the Persian New Year. His groceries cost $150
before he uses a 10%-off coupon. He also
orders $60 worth of flowers. Sales tax on the
flowers is 6.25%. What is the total amount
Cyrus spends?
Answer:
$198.75
Step-by-step explanation:
total amount spent = cost of groceries + cost of flowers
total cost of groceries = initial cost - coupon value
coupon value = 0.10 x 150 = $15
Total cost = $135
total cost of flowers = cost of flowers + tax value
tax value = 0.0625 x $60 = $3.75
total cost of flowers = $3.75 + $60 = $63.75
total amount spent = $135 + $63.75 = $198.75

Step-by-step explanation:
A rectangular garden has dimensions of 100ft by 10ft next season the garden is decreased by 2/3 of its size what is the scale of the new drowning
The qyaeriin has no attached diagram. A related diagram was found and used to provide the steps required to solve the problem.
Answer:
1 inch = 8.333 feets
Step-by-step explanation:
Initial dimension of rectangle :
100 feets by 10 feets
Fractional decrease in garden = 2/3
New Dimension of garden :
2/3(100 feets) by 2/3(10 feets)
66.667 feets by 6.6667 feets
Hence
From the picture attached :
8 inch = 66.667
1 inch = 8.333
The new scale of the drawing = 1 inch = 8.333 feets

These cylinders are similar. Find the surface
area of the smaller cylinder. Round to the
nearest tenth.
5 cm
13 cm
Surface Area = [? ] cm2 Surface Area = 236 cm2
Answer:
[tex]A=141.6\ cm^2[/tex]
Step-by-step explanation:
The surface area of a cylinder is given by :
[tex]A=2\pi rh[/tex]
For larger cylinder, A = 236 cm² and h = 5 cm
So,
[tex]236=2\pi \times 5\times r\\\\r=\dfrac{236}{10\pi}\\\\r=7.51\ cm[/tex]
Now, Put r = 7.51 and h = 3 cm to find the surface area of the smaller cylinder.
[tex]A=2\pi \times 7.51\times 3\\\\A=141.56\ cm^2\\\\A=141.6\ cm^2[/tex]
So, the surface area of the smaller cylinder is equal to [tex]141.6\ cm^2[/tex].

number 29 and 30 pleasseeeee
Answer:
29 = 16.4
30=
Step-by-step explanation:
The formula for finding a hypotenuse is a^2 + b^2 = c^2. Therefore, if you want to solve 29 you would do 13^2 + 10^2 = c^2.
13^2= 169
10^2=100
269+100 = c^2
368= c^2
So next, we have to do the square root of 368 which is 16.4.
Now for number 30, we know that it is a right triangle. So if we want to work with that, we have to find the angles of everything. We know that the sum of all angles in a triangle is 180. So a right angle is 90 degrees. We have 90 left over. Could you solve the rest?
