Answer:

2. tan 280°

3. -tan 80°

Step-by-step explanation:

Your calculator can help you figure this out.

The tangent function is periodic with a period of 180°, so tan(100°) will be equal to tan(100°+k·180°) for any integer k. Answer choices include k values of ±1, so two of them are correct:

tan(100°) = tan(100° -180°) = tan(-80°)
tan(100°) = tan(100° +180°) = tan(280°)

Answer:

<h2>Slope = 2</h2>

<u>Step-by-step explanation:</u>

co-ordinates = (2,2) and (-1,-4)

A produce supplier ships boxes of produce to individual customers. The distribution of weights of shipped boxes is approximately

schepotkina [342]

Answer:

$0.67(4)+ 36$

Option D

Step-by-step explanation:

Given that a producer ships boxes of produce to individual customers.(say x)

X is a normal random variable with mean = 36 and std dev =4 lbs

By definition of std normal variate we know that

$\frac{x-36}{4}$ is N(0,1)

75th percentile of std normal distribution is

0.675

Hence corresponding x would be

$36+0.675(4)$

Option D matches with this value

Hence answer is option D

$0.67(4)+ 36$

Since 18% is 18/100 you just have to multiply the $842.4 by the reciprocal of that to find your answer
Reciprocal of 18/100 is 100/18
842.4* 100/18 equals 84240/18
84240/18 equals 4680
