Checking if the sequence is an arithmetic sequence
7 - 1 = 6
13 – 7 = 6
Therefore the sequence is arithmetic, with a_0 = 1 and d = 6
a_n = a_0 + (n-1)d
a_30 = 1 + (29)(6)
= 175
Therefore the 30th term is 175.
Answer:
D
Step-by-step explanation:
I think it is D because exponential graphs usually have a curve to them. And the one you need is exponential decay so D is negative and exponential.
HOPE THIS HELPS! HAVE A GREAT DAY!! :)

Answer:
r <5
Step-by-step explanation:
r-4<1
Add 4 to each side
r-4+4<1+4
r <5
Answer:
Null hypothesis; H0: µ ≥ 52 mpg
Alternative hypothesis; Ha: µ < 52 mpg
Step-by-step explanation:
We are told that the newest model gets an average of 52 miles per gallon and that the buyers believe that the average mpg was overstated.
This means the alternative hypothesis will have an average less than 52. Thus;
Null hypothesis; H0: µ ≥ 52 mpg
Alternative hypothesis; Ha: µ < 52 mpg
