<span>Yes, it is a parallelogram because the slope of segment AB equals the slope of segment DC, which equals negative start fraction four over three end fraction, and AD = BC = 10 units.</span>
Of course it is c. range would show the difference between the highest and lowest scores, there is no mode in her data set, and the median is the middle point of the data set
<span>1x + 2x = 15
3x = 15
3x/3 = 15/3
x = 5
Gemma = 1x, Zak = 2x therefore Gemma = 5 and Zak = 10</span>
Answer:
C. 4 weeks
Step-by-step explanation:
We have the formula

We are looking for the value of t (number of weeks) when s = 150.
So, we isolate t (well, almost isolate, because it would be hard to read)

If we replace s by 150 we get:

We have 7t = 30.25. If we divide both sides by 7 we get the number of weeks: 4.32... so rounding it down to 4.
