5/9
Using a table of outcomes, you can see that 20 of the possible 36 outcomes are even totals. Simplify for the 5/9 or roughly 56%
Hello,
P(x)=x^3-7x-6
P(4)=4^3-7*4-6=30
Remainder=30
Answer:

--- Variance
Step-by-step explanation:
Given

Solving (a): Calculate the mean.
The given data is a grouped data. So, first we calculate the class midpoint (x)
For 51 - 58.

For 59 - 66

For 67 - 74

For 75 - 82

For 83 - 90

So, the table becomes:

The mean is then calculated as:



-- approximated
Solving (b): The sample variance:
This is calculated as:

So, we have:


-- approximated
40,978 would be the answer hope it helped!
Answer: I think this is how we do it but i am not sure the answer is 48
Step-by-step explanation:
if the price increase by 3/4 then that mean it total will be 7/4 as 4/4 is it original price add so 7/4=84/x 84x4 is 336 336 divide by 7 is 48 to check 48 x 7/4 or 48 x 3/4 and add 48 if u math is correct than u should get 84
