5
Step-by-step explanation:
He will weigh 198 lbs. you add 3 lbs to his original weight for each year.
Step-by-step explanation:
2x+8=2x+5
2x-2x=15-8
0x=7
Solution :
The null and alternative hypothesis is given by


Assume that the level of significance, α = 0.05
The t-test statistics is, t = 1.484
Degree of freedom :
df = n - 1
= 14 - 1
= 13
The P-value is given by
P-value = 2P (T>|t|)
= 2P(T>|1.484|)
= 2P(T>1.484)
= 2(=T.DIST.RT(1.484,13))
= 0.05
A polynomial function with all even exponents is so-called even function.
Even functions are symmetric across the y-axis.
Answer: Only one that is symmetric across the x-axis is the function C ).
