The answer is 26.6 ft because 31×31 - 16×16 is 705 and the square root of 705 is 26.55183609
Hey there! :)
Answer:
1.
Step-by-step explanation:
If a line has the equation y = x + 6, a parallel line would contain the same slope.
In the equation y = x + 6, there is no coefficient, or slope. This means that the slope, or m = 1.
Thus, a parallel line would contain an equivalent slope, making the slope of the parallel line = 1.
Answer:
x = 6
z = 60
Step-by-step explanation:
Solve for x
(6x + 84) = 120
- 84 -84
6x = 36
6x/6 = 36/6
x = 6
Then solve for z
120 + z = 180
-120 -120
z = 60
A = base * height
A = 10 *17
A =170
170 is the correct answer
Answer:
There is a 82% probability that th esample mean annual sales per square foot is at least $384.
Step-by-step explanation:
We have a population with mean 390 and standard deviation 45.83.
Samples of size n=49 are taken.
The parameters of the sampling distribution are:
First, we have to calculate the z-score that satisfies:
This z-score, looked up in a standard normal distribution table, is z=-0.915.
Then, we can calculate the sample mean as:
There is a 82% probability that th esample mean annual sales per square foot is at least $384.
