Answer:
The sum of any integer and its opposite is equal to zero. Adding two positive integers always yields a positive sum, adding two negative integers always yields a negative sum. To find the sum of a positive and a negative integer, take the absolute value of each integer and then subtract these values.
Answer:
C. Over the course of many games, one would expect the mean number of hits per game to be the mean of the random variable.
Step-by-step explanation:
Mean is the ratio of sum of observations to the total number of observation.
It represent the whole data. Thus, Mean of hits per game is the mean of those hits of game. Thus, option C is correct.
mean is based on all the observation not few or most. Thus Option A is incorrect.
Observations are different from mean, So hits per game can be different from the mean of hits of game. Thus, Option B is incorrect.
The Mean of hits per game can be less and more from half of the observation. It is totally depends on the value of the observations. Thus, We can't chose option D as correct.
Answer:
-9 3/4a+10 2/5
Step-by-step explanation:
-12 * 5/6a = -10a
-12 * -7/8 = 10 1/2
1/14 * 3 1/2a = 1/4 a
1/14 * -1 2/5 = -1/10
Put it together: -10a + 10 1/2 + 1/4a - 1/10
-10a+1/4a = -9 3/4a
10 1/2-1/10= 10 2/5
-9 3/4a + 10 2/5
Hi,
Answer:
100 m^2
Step-by-step explanation:
Formula to find area: A = 
p: 5 + 5 = 10
q: 10 + 10 = 20
20 * 10 = 200
200/2 = 100
Have a nice day!
