Step-by-step explanation:
Given : A study of the amount of time it takes a mechanic to rebuild the transmission for a 2005 Chevrolet Cavalier shows that
Mean :
Standard deviation :
Sample size :
Let be the sample mean.
The formula for z-score in a normal distribution :
For
The P-value =
Hence, the probability that their mean rebuild time is less than 8.9 hours is 0.9608 .
Answer:
The correct answer is A) 76 degrees
Step-by-step explanation:
In order to solve the equation for mT, we can use trigonometric functions. Since we are given the side adjacent to the angle and the hypotenuse, we'll use cos.
Cos(α) = ADJ/HYP
Cos(α) = 4/17
Cos-1(α) = .235
α = 76 degrees
Answer:
50.27

Answer: $14
Step-by-step explanation:
Hi, to answer this question we have to multiply the amount of the cash advance (700) by the APR for cash advances in decimal form (divided by 100):
700 x (24/100) = $168 (a year)
To obtain the monthly charges, we have to divide the result by the number of months in a year (12):
168 /12 = $14
Feel free to ask for more if needed or if you did not understand something.
So you need to replace X with a number, let’s say 4 in this example. 2 x 4 - 5 + 4 x 4 > 2 x 4 - 1 which is basically 19>7
