The chemco company manufactures car tires that last distances. assuming such distances are normally distributed with a mean 36000 miles and a standard devaition 4200 miles in a tire is selected, what is the probabilty it lasts less than 30000 miles if such a random sample of 100 tires had a mean lasting distance of 30000 what can you say about the companies claim

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )

i need points

step-by-step explanation:

sorry bubs

yx = 36

step-by-step explanation:

cos f = opposite side/ hypotenuse

cos f = yw / yx

we know cos f = 4/9 and yw =16

4/9 = 16/yx

multiply each side by yx

4/9 yx = 16/ yx * yx

4/9 yx = 16

multiply each side by 9/4

9/4 * 4/9 yx = 16 *9/4

yx = 36
