Answer:
c. 154 yd²
Step-by-step explanation:
Given
Diameter (d) = 14 yd
radius (r) = 14/2 = 7 yd
Area of the circle
= π r²
= 22 /7 * 7 * 7
= 154 yd²
I think the answer is between the 8 and the 10
Answer:
I believe the answer would be 118; the reason for that would be you would take $120 then take $22 and add it to the amount because withdrew means you are taking money out so how ever much money you took out would be the amount that you had in your saving. Then if you are depositing $20 you would subtract that amount of money because deposit means that you are adding that money to what you add so you would then subtract that to get the original amount.
Answer:
2.35%
Step-by-step explanation:
First, calculate the difference between mean and the months in the problem:
first month :59 – 26 = 33
second motnh: 59 – 37 = 22
Since standard deviation is 11 months, for the first month is a difference of 3 standard deviation and for the second is 2 standard deviation.
the 68-95-99.7% rule establish that:
1 standard deviation means a 68% of total area under the normal distribution. On one side is half = 34%.
2 standard deviations means a 95% of total area under the normal distribution. On one side is half = 47.5%.
3 standard deviation means a 99.7% of total area under the normal distribution. On one side is half = 49.85%.
The difference between 3 and 2 standard deviation is
49.85 – 47.5 = 2.35%
The answer is 2.35% of cars that remain in service between 26 and 37 months
Answer:
The vertex of a quadratic equation corresponds to the point where the maximum or minimum value is located.
If the function has a positive leading coefficient, the vertex corresponds to the minimum value.
If it has a negative leading coefficient, the vertex corresponds to the maximum valuevalue
If the vertex is located at
(–2, 0)
The possibilities are
y = (x-2)^2
or,
y = - (x-2)^2
Since the problem tells us the answer, we adopt the positive values
Answer:
y = (x-2)^2
