Answer:
12
Step-by-step explanation:
9+3=12. therefore 12 is your answer
Step-by-step explanation:
Equation (1) is :
x+2=5
Subtract 2 from both sides,
x+2-2=5-2
x=3
Equation (2) is :
2n+5=n
Taking like terms together,
2n-n=-5
n=-5
Equation (3) is :
5(x+2)-7=3x+5
⇒5x+10-7=3x+5
taking like terms together,
5x-3x=5-10+7
⇒2x=2
x=1
Hence, x =3, n = -5 and x = 1 is the required answer.
Answer:
The answer is 3,019.92 cubic millimeter
Step-by-step explanation:
take 375 plus 375 to get 750
then 3769.91 - 750 to get the 3,019.92
Answer:
The standard error of the sample mean is 0.57
Step-by-step explanation:
we know that
The Standard Error Formula is given by the formula

where:
SE = standard error
s = standard deviation
n = the sample size
In this problem we have

substitute in the formula


Answer:
No. 1 , 3 and 5 is correct.
