Answer:
B.
Step-by-step explanation:
x represents the amount of guests going to the birthday party, with the amount of money per guest being 12. You would multiply those two together, but as we do not know the total amount of guests, we keep it as a variable. 125 is the amount before the guests even know about the party, so therefore, you would need to use that equation.
Answer:
the sample standard deviation is 4.926 pounds
Step-by-step explanation:
the sample standard deviation s is defined as
s =√[ 1/(n-1) ∑ ( x- m)²] for x=1 to x=n
where
n= sample size = 10
x= weights of defensive tackles
m= sample mean
m= 1/n ∑ x* for x=1 to x=n
then
m= 1/10 (202 + 215... +208) = 209.66 pounds
thus
s =√[ 1/(10-1) ∑ ( x- m)²] = √[ 1/(10-1) [ ( 202 - 209.66 )² + ( 215 - 209.66 )² + ( 28 - 209.66 )² ] ] = 4.926 pounds
then the sample standard deviation is 4.926 pounds
Answer:
30
Step-by-step explanation:
7 * 3 = 21
3 * 3 = 9 which covers for both triangles
each triangle is half of a square. so each triangle is 4.5 sq. units
add 21 with 9
21 + 9 = 30
Answer:32
Step-by-step explanation:
- u fist find the total ratio 4+1 =5
then the ratio belonging to apple is four
so u divide 4 by 5 then multiply to the total no of fruit
and that will give u 32
29.1 just divide but frist u have to line up your decimal then divide
