A manufacturer knows that their items have a normally distributed length, with a mean of 14.5 inches, and standard deviation of 1.5 inches. If one item is chosen at random, what is the probability that it is less than 15.1 inches long?
0.15

answer: 1 + 1 = 11

step-by-step explanation:

it’s the first one your welcome

idk what the heck he answer is, i’m just putting this here so i finish my account

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.
