Answer:
Mean=50
Step-by-step explanation:
The mean of a probability distribution is a <u>measure of central tendency</u>,and gives information about how the possible values of x are distributed.
The vertical axis measures the probability of finding a specific value of x in the sample. The probability of finding a value near the mean is high (that is why the value of the function that is depicted in the vertical axis, increases as we get closer to the mean=50): this is because the mean is that value of x around which higher probability of occurrence is associated.

Let x be that number
2x -3 = x-6 solve for x ; x=-3
Answer:
1. subtraction 2. division 3. division 4. multiplication
Step-by-step explanation:
I would say there is 18 girls in the club b/c the ratio is 3:4 there would be one more group of boys than girls. you divide 24 by y and you then subtract 6 from 24 to get 18.
You subtract 4/9x frm 8/9x which is 4/9x = 8 then you multiply 9 to 8 so it is 4x = 72. After that, you divide 4 from 72 and get 18
