Answer:
<h3>102. 66 feet / Second</h3>
Step-by-step explanation:
To do conversion change miles into feet and hour into second.
One foot is 5280 feet
And an hour is 3600sec
70 miles / Hour
70 * 5280feet / 3600 second
369600 feet / 3600seconds
Then simplify
102. 66 feet / Second
Answer:
What are you trying to ask
Step-by-step explanation:
The correct option is 20.
The score found for the sample is 20.
<h3>What is Standard error?</h3>
A standard error is a statistic that is applied to test the distribution of data. This metric is comparable to standard deviation. We can calculate the standard error if we know the sample size & standard deviation. It assesses the mean's precision.
Now, according to the question;
Sample mean; 
Sample variance; 
Thus, 
Standard error SE = 1
The amount of scores with in sample must be determined here.
The standard error formula is as follows:

We might rearrange the formula as follows:

Substituting the values;

The sample's number of scores n = 19.98 = 20 (round up)
Therefore, the scores are in the sample is 20.

ANSWER

EXPLANATION
We want to find the absolute value function for the line in blue.
The general form of an absolute value function is:

where (h, k) = vertex
From the line, the vertex of the graph in blue is:

To find a, we have to pick a point (x, y) on the line and input it into the general function.
Let us pick (2, 1).
Therefore, we have:

Therefore, the absolute value function is:
A and D
Put 3 in the equations and solve
