Step-by-step explanation:
15/3=5 so 16*5=80
1/3 ÷1/4 = 1/3 × 1/4 = 1/12
6.) D (x+7)(x+1)
7.) B (x-9)(x+8)
8.) D
9.) A
10.)A
Answer:
Mean: For this case would be not useful since in the stem leaf plot is difficult to find this measure with this chart
Step-by-step explanation:
We want construct a stem and leaf plot and we want to find the measure least useful.
And for this case if we analyze the option we have:
Range: That very useful and it can be extracted from the stem and leaf plot
Median: It could be easy to find it with the stem leaf plot
Mode: With a stem leaf plot we can find easily the most repeated value
Mean: For this case would be not useful since in the stem leaf plot is difficult to find this measure with this chart
X=-2x-5 x=3
x=-2(3)-5
x=-6-5
x= -11
