Answer:
-17
Step-by-step explanation:
15=-3(h+12)
1. Do distributive property
15=-3h-36
-3h=51
H=-17
Answer:
68%
Step-by-step explanation:
We observe that the mean of the sample is (61+71)/2 = 66 mph which means the standard deviation of the sample is 5 because 66-5=61 and 66+5=71. The Empirical Rule states that for data observed in a normal distribution, 68% of data will fall within one standard deviation of the mean. Therefore, approximately 68% of vehicles travel between 61 miles per hour and 71 miles per hour.
It has 4 extinct variables in the equation.
I don't know how to use as a bar diagram, but all I know is the solution is 30 students in the class. 8/10=24, so 10/10=x, since (10/10)/(8/10)= 5/4, then you multiply 24 by 5/4 to get 30 students as your answer.
Hope I'm a brainliest for this question!
