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:
$35
Step-by-step explanation:
all you have to do is 40-5=35
which tells you that you have $35 left
The correct answer is 36pi.
When in point-slope form, the number next to the y and the x by themselves will be the opposite of what they would actually be as coordinates. This means that the y-coordinate, -1, will show up as y+1. This eliminates A and B out of the choices.
The slope is -3, which will be the number outside of the parentheses, which is what we see in C’s answer or -3(x-10).
Therefore, the answer is C: y+1 = -3(x-10).
Answer:
The area of a triangle is: A = 23.2 cm²
Step-by-step explanation:
Given
a = 10 cm
b = 9 cm
The angle ∠C = 31°
To determine
Area of the triangle
Using the formula to determine the area of the triangle
Area = 1/2bc sin C
substituting a = 10, b = 9, and m∠C = 31°
Area = 1/2 × 9 × 10 × sin 31°
Area = 1/2(90) sin 31°
Area = 45 × sin 31°
Area = 23.2 cm²
Therefore, the area of a triangle is: A = 23.2 cm²
