Recent studies indicate that the typical 50-year-old woman spends $350 per year for personal-care products. the distribution of the amounts spent follows a normal distribution with a standard deviation of $45 per year. we select a random sample of 40 women. the mean amount spent for those sampled is $335. what is the likelihood of finding a sample mean this large or larger from the specified population

i think is g(1)=-1.

hope that i can

it would open into a square depending on the type of envelope i’m not sure about the second part

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.

where's the diagram?
