Answer: This equation does not have a vertex.
If the equation is not curved or composed of two straight lines it does not have a vertex.
If you need further explanation let me know. :)
The answer is C, the commutative property of multiplication.
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
The factors of 189 are: 1, 3, 7, 9, 21, 27, 63, 189.
1 × 189 = 189
3 × 63 = 189
7 × 27 = 189
9 × 21 - 189
The answer is d=6 i can show my work in the comments if you need it
