I asked my brother and he said it was 12. I don’t know if he’s right but I hope it is ;)
If you multiply 23 by 12 you will get 276.
Answer:
Step-by-step explanation:
Let's follow what the problem asks us:
- "The area of a square with side length x"
this is the formula for area:
since the side length is x, the initial area is:
- Now, "where the side length is decreased by 3":
The side is now , thus the area is:
- "the area is multiplied by 2"
we had the area , when we multiply by 2:
- And finally " then 4 square units are added to the area."
this is:
Answer:
There is significant evidence that treatment will create effect on the subject. Hence We reject H0
Step-by-step explanation:
H0 : μ = 37
H1 : μ ≠ 37
μ = 37 ; σ = 7 ; sample size, x = 51 ; sample size, n = 1
Decision region :
If P value < α ;
Reject H0
Using the Z test statistic :
Zstatistic = (x - μ) ÷ (σ / √n)
Zstatistic = (51 - 37) ÷ (7 / 1)
Zstatistic = 14 ÷ 7
Zstatistic = 2
Obtaining p value from Zstatistic using the p value calculator ;
Zscore = 2 ; 2-tailed test, significance level = 0.05
P value = 0.0455
Zcritical at α = 0.05 for a 2 - tailed test = 1.96
0.0455 < 0.05
There is significant evidence that treatment will create effect on the subject. Hence We reject H0
