The interior angles in any triangle sum to 180 degrees, so the measure of angle E is 180 - 65 - 50 = 65 degrees.

Assuming side d is opposite angle D, side e is opposite angle E, and side f is opposite angle F, we can use the law of sines to determine the side lengths e and f.

$\dfrac{\sin D}d=\dfrac{\sin E}e=\dfrac{\sin F}f$

$\dfrac{\sin50^\circ}{7.5}=\dfrac{\sin65^\circ}e\implies e\approx8.87$

Angles E and F have the same measure, so $f\approx8.87$ as well.

1. A motorboat leaves a harbor and travels at an average speed of 15 mph toward an island. The average speed on the return trip

Answer:

30 miles

Step-by-step explanation:

Let d represent the distance to the island. The relation between time, speed, and distance is ...

time = distance/speed

so the total time for the round trip is ...

d/15 +d/10 = 5

Multiplying by 30, we get

2d +3d = 150

d = 150/5 = 30

The island was 30 miles from the harbor.

1. Use Excel to answer the following. In each question, find the blank to make the statement true. Note that Z represents we are

Sati [7]

Answer:

1. A: 0.25; B: 0.03; C: 1.41; D: -0.28

2. A: 0.39; B: 0.06; C: 40.30; D: 21.81

Step-by-step explanation:

For CDF lookups, we used the Excel NORMDIST(x, mean, stdev, TRUE) function. For inverse CDF lookups, we used the NORMINV(x, mean, stdev) function.

Each of these functions works with the area under the curve from -∞ to x, so for cases where we're interested in the upper tail, we subtract the probability from 1, or subtract the x value from twice the mean.

For question 1, we computed the Z values in each case. The NORMDIST function works directly with x, mean, and standard deviation, so does not need the z value.
