Answer:20 is the least common
Step-by-step explanation:
Answer:
y=qx
Step-by-step explanation:
*Note to think about The Slope Intercept equation is y=mx+b, where m is the slope, b is the y-int, and x,y is an ordered pair on the line.
1. Here the slope is q, and the y-intercept is 0.
2. Now plug in the known variables in for the unkowns
y=qx+0
3. we can take out the zero because anything plus/minus zero is itself, so the answer is:
y=qx
16.6 is the answer. 16 is the whole number so u just divide 3 and 5 and get .6
Answer:
Mean = 0.45
Standard deviation = 0.04035
Step-by-step explanation:
This is actually a very simple problem.
The question gives us the report that 45% of the teenagers in the age bracket own smartphones.
P = mean = 45%
Therefore the mean is 0.45.
I will go ahead to help you calculate the standard deviation.
√p(1-p)/n
n = 152
P = 0.45
√0.45(1-0.45)/152
= √0.45(0.55)/152
= √0.2475/152
= √ 0.001628
= 0.04035
