</span>Which is... C) 95kg
An easy way to check your answer is right is to add 95 to 180.
180 + 95 = 275
275=275
The answer checks out!
Answer
I think you just draw a line from 9 to 4, i'm not so sure tho.
Step-by-step explanation:
*Snarls at my own stupidity*
1. analyze data presented
It is not d because it is not greater than 80 degrees
it is not a because it is clearly not 10 degrees
making system of equations
8x+(4x+60)=180
addition
12x+60=180
move sixty to the other side
12x=120
division
x=10
Angle BEC=*x, so 8x=80
Answer: 80 degrees
Answer:
14 - hope this helped :)
Step-by-step explanation:
42 divided by 3
= 13
therefore
42/3 is simplified to 14
Answer:
2
Step-by-step explanation:
We have
n = 4 scores
SS = 48
For this question, we are required to find the estimated standard error
To get this, we first solve for the variance
S² = SS/n-1
= 48/4-1
= 48/3
= 16
Then S² = 16
S = √16
S = 4
Then the estimated standard error is given by:
S/√n
= 4/√4
= 4/2
= 2.
The estimated standard error is 2.
