You just add the values for volunteers that worked 16-20 hours and 21-25 hours which would be 50 + 10 = 60. So the total number of volunteers that workers more than 15 hours is 60.
Im pretty sure you put the wrong picture. The slope isn't negative and there is no point O,A, or B.
Answer:
B. x =1 , y = -5
Step-by-step explanation:
So, what we can do is to simply plug in all of the equations and see which one fits. Equation: x - y = 6
A. x =1 , y = -6
1 -(-6) = 6
1 + 6 = 7
A would be incorrect.
B. x = 1, y = -5
1 - (-5) = 6
1 + 5 = 6
Therefore, B would be correct.
Answer: D. History
Step-by-step explanation:
To answer this question, we need to use the z-score formula written below:
Now we'll just plug in the numbers and solve.
History:
Biology:
As we can see, history wields a higher z-score than biology, thus leaving us with option D. History
Answer:
The answer is the first option I hope it helps
