Answer:

1. adjacent angles and complementary

2. vertical angles

3. supplementary angles and linear pairs

4a. right angle

4b. I'm a little confuse what they're asking for that they're epecting a word but I can give you a number which is 90 degrees. It makes the most sense but I don't know.

5. 20 degrees

6. is confusing because they're referencing two images

<------/--------> (draw a horizontal line and a line in the middle. Put angles that equals to 180 in total

Sorry this isn't 100% correct but at least I tried and helped.

Assume that it takes a college student an average of 10 minutes to find a parking spot in the main parking lot. Assume also that

rjkz [21]

Answer:

75% of college students exceed 6.63 minutes when trying to find a parking spot.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 10 minutes

Standard Deviation, σ = 5 minutes

We are given that the distribution of time for parking is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

P(X < x) = 0.25

We have to find the value of x such that the probability is 0.25.

P(X < x)

$P( X < x) = P( z < \displaystyle\frac{x - 10}{5})=0.25$

Calculation the value from standard normal z table, we have,

$P(z$

$\displaystyle\frac{x - 10}{5} = -0.674\\x = 6.63$

Hence, 75% of college students exceed 6.63 minutes when trying to find a parking spot.
