Answer:
Yes, we reject the auto maker's claim.
Step-by-step explanation:
H0 : μ ≥ 20
H1 : μ < 20
Sample mean, xbar = 18 ;
Sample size, n = 36
Standard deviation, s = 5
At α = 0.01
The test statistic :
(xbar - μ) ÷ s /sqrt(n)
(18 - 20) ÷ 5/sqrt(36)
-2 /0.8333333
= - 2.4
Pvalue from test statistic : Pvalue = 0.00819
Pvalue < α
0.00819 < 0.01
Hence, we reject the Null
A3=3
a4=5
a5=8
This sequence has properties similar to those of the Fibonacci sequence.
Answer:
b is the answer by solomon
Look it up on the internet youll find the answer there i am only learining about adding integers right now
Solve the equation for x:
4x+12=48
Subtract 12 from both sides: 4x=36
Divide 4 from both sides to isolate x: x=9
