You don't even have to look up the definition of 'standard deviation'. You only
have to remember that 'smaller standard deviation' means 'less spread-out'.
First, let's find the mean (average). It's not supposed to change:
1/7th of (65 + 71 + 77 + 80 + 82 + 90 + 96) = 561/7 = <u>80 and 1/7</u> .
Now, just pick 7 scores that total 561 and are all bunched up.
The easiest way would be 80, 80, 80, 80, 80, 80, 81 .
But that's so easy that it feels like cheating.
Let's say <u>77, 78, 79, 80, 81, 82, and 84</u> .
Answer:

Step-by-step explanation:
You may have entered the measure of a side as the measure of an angle.





You are correct. Good job!
Length = x - 2
Width = x - 5
Explanation:
Area = x^2 - 7x + 10
Area = (x - 2)(x - 5)
Area = Length x Width
Length = x - 2
Width = x - 5
Answer:
$1596
$1597.28
$1598.33
bank A
Step-by-step explanation:
The formula for calculating compound interest:
FV = P (1 + r/m)^mn
FV = Future value
P = Present value
R = interest rate
N = number of years
m = number of compounding
Bank A = $1500(1.064) = $1596
Bank B = $1500( 1 + 0.063/12)^12 = 1597.28
Bank C = $1500( 1 + 0.0635/365)^365 = $1598.33
Bank A pays the least amount of interest
