The average number of miles (in thousands) that a car's tire will function before needing replacement is 60 and the standard deviation is 16. Suppose that 11 randomly selected tires are tested. Round all answers to 4 decimal places where possible and assume a normal distribution a. What is the distribution of X X NO b. What is the distribution of a?o - N c. If a randomly selected individual tire is tested, find the probability that the number of miles (in thousands) before it will need replacement is between 65.2 and 67.8. d. For the 11 tires tested, find the probability that the average miles (in thousands) before need of replacement is between 65.2 and 67.8. e. For part d), is the assumption that the distribution is normal necessary? No Yes​

the correct answer is you spend $55.78 more in a brand store that buy ing in a normal store.

step-by-step explanation:

brand = spend   $ 135.85 total

store = spend $80.07 total

i dont get the question

step-by-step explanation:

answer: 2 answers

step-by-step explanation: the first one means to spread the product throughout the marketplace such that a large number of people can buy it.  

the second means the process of making a product or service available for the consumer or business user that needs it.

mark this brainliest and i will be glad to .

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
