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:
u should better search the google or this site www.edkasa.edu.pk u will defiantly find the answer.
Answer:
The function is neither even or odd
Step-by-step explanation:
Multiply the first equation by 2 or divide the second one my 2, to get the #X opposites, to cancel each other out
-4x+6y=12
4x-6y=-6
Or
-2x+3y=6
2x-3y=-3
there’s no solution either way
Answer:
A
Step-by-step explanation:
Calculate the midpoint using the midpoint formula
[ 0.5(x₁ + x₂ ), 0.5(y₁ + y₂ ) ]
with (x₁, y₁ ) = (- 1, 5) and (x₂, y₂ ) = (5, 5)
midpoint = [ 0.5(- 1 + 5), 0.5(5 + 5) ]
= [ 0.5(4), 0.5(10) ] = (2, 5 ) → A
