Step-by-step explanation:
(a) A histogram is like a bar graph, but with ranges instead of values.
(b) The distribution is approximately uniform, with slightly more people at the younger and older ends than in the middle.
(c) The ages do not appear to come from a normal distribution. Normal distributions are bell-shaped, tall in the middle and short on the sides.
We have a property for odd functions, which is given below. Let f(x) be an odd function then it must satisfy the below - mentioned property.

Now, we have been given the function 
For this function to be odd, it must satisfy the above written property.
Replace x with -x, we get

And, we have to also find

Hence, in order to the given function to be an odd function, we must determine whether 9-4(-x)^2 is equivalent to -(9-4x^2) or not.
Therefore, C is the correct option.
Answer:
a = 9
b = 19
Step-by-step explanation:
DO B FIRST
The mean is the average of all the terms (numbers) in the sequence
To find the average you find the sum of the terms and divided the sum by the number of terms there are.
The mean times the number of terms equals the sum of all the terms subtract the terms that you know from the sum to get A
a = 17(10)-7-12-15-17-19-20-22-24-25
a = 170-161
a = 9
The median is found by taking the average of the two middle terms
Our middle terms are 17 and B
the median times 2 equals the sum of the two terms and then subtract the term you know from the sum
b = 18(2)-17
b = 36-17
b = 19
Answer:
Isaac's total bill is $84.53
Step-by-step explanation:
$37.00 + $42.00 = $79.00 < <em>b</em> (bill)
<em>b</em> + <em>t</em> (sales tax) = <em>c</em> (total cost)
(7%/100 = 0.07)
(0.07 * 79 = 5.53)
(<em>t</em> = $5.53)
$79.00 + $5.53 = $84.53
Good luck!!
