Answer:
The finish line
Step-by-step explanation:
Jonas is planning his trip using the finish line as reference point. He is using an interval scale (using meters as measurement) and the finish line = 0 meters or the starting point. Anything before the finish is negative and anything after is positive. In this case, his wife is located at 91 + 14 = 105 meters away from him. When you use an interval scale to measure distance, you must use absolute values to determine the distance because positive and negative points.

Answer:
B
Step-by-step explanation:
Variance can be said to be a measure of dispersion for a random sample.
Variance = pq/n
When given the variance, we can find the standard deviation.
Standard deviation = √variance
= √pq/n
Answer:
y = 3
Step-by-step explanation:
substitute the x in 2x - y = 7 by x = 3y - 4 and then solve
2(3y - 4) - y = 7
<em>Distribute the 2 into the parenthesis</em>
6y - 8 -y = 7
<em>combine like terms</em>
5y - 8 = 7
<em>add 8 on both sides</em>
5y = 15
<em>divide by 5 on both sides to isolate the y-value</em>
y = 3
