Answer:
76.8
Step-by-step explanation:
The mean is the sum of the values divided by the total number of values.
63+73+92+63+93 / 5 =
384 / 5 = 76.8
Answer:
it is 4xy-4y^2+16x-16y
Step-by-step explanation:
My method is to "square them"
2x. -2y.
2y
8
2x * 2y
2x * 8
-2y*2y
-2y * 8
and add all the products together
Answer:
$1200
Step-by-step explanation:
The clustering method for estimation is a method used for estimating the sums and products of numbers. This method is used when the numbers that are to be multiplied or added are near in value to a single number.
Given the money raised by six fund raisers:
$212, $205, $206, $190, $188, and $195
The numbers are to be added to find the total money raised. i.e.:
$212 + $205 + $206 + $190 + $188 + $195
But all the numbers are close to $200. Hence:
Using clustering method = $200 + $200 + $200 + $200 + $200 + $200 = 6 * $200 = $1200
3 and 4 would both be corrent because one is smaller is 2 would make it equal
