Answer: 11378.58 ft
Step-by-step explanation:
1. Draw a figure like the one attached, where A is the position of the airplane and B and C are the positions of the cars.
2. The distance between the cars is the length BC, then, you need to calculate the measure of BD and DC to add them and obtain BC.
<h2> 3. You know the opposite side and the angles of depression, then, you can calculate the distance between the cars as following:</h2>
Answer:
x=-7
x=7
Step-by-step explanation:
we have
Solve for x
Adds 98 both sides
Divide by 2 both sides
take square root both sides
therefore
The solutions are
x=-7
x=7
Answer:
C. Probability is 0.90, which is inconsistent with the Empirical Rule.
Step-by-step explanation:
We have been given that on average, the parts from a supplier have a mean of 97.5 inches and a standard deviation of 6.1 inches.
First of all, we will find z-score corresponding to 87.5 and 107.5 respectively as:
Now, we need to find the probability .
Using property , we will get:
From normal distribution table, we will get:
Since the probability is 0.90, which is inconsistent with the Empirical Rule, therefore, option C is the correct choice.
