Answer:
Since p is > α we fail to reject the Null as the result is not significant at α = 0.05
Step-by-step explanation:
Given that:
Mean lifetime (m) = 1200
Sample size (n) = 25
Sample mean (x) = 1180
Standard deviation (s) = 80
α = 0.05
The null hypothesis :
H0 : m = 1200
Alternative hypothesis : m ≠1200
The t statistic :
(x - m) / (s/√n)
(1180 - 1200) / (80 / √25)
-20 / (80/5)
= - 1.250
P value = 0.10565 ( p value calculator)
Reject Null hypothesis if p > α
At α = 0.05
Since p is > α we fail to reject the Null as the result is not significant at α = 0.05
ANSWER:
$6113.20
EXPLANATION:
There is two ways to make an expression to solve this which is
y = 1.16x
or
y = x + 0.16x
Here is the explanation for the first expression, it is more thorough:
The airline makes her pay x amount in dollars for the ticket alone. Then, the airline charges an additional 16% of that x amount. Just a policy they’ve required.
Therefore:
y = x + 0.16x
• x is the ticket price
• 0.16x is 16% of that ticket price
Plug x with the initial charge amount:
y = 5270 + 0.16(5270)
y = 6113.20
Answer:
1) ST > MN
2) BA > BC
3) angle A > angle F
4) angle L < angle R
Step-by-step explanation:
In all cases the sides adjacent to the specified angle are unchanged in both triangles.
Decreasing the angle decreases the opposite side.
Decreasing the opposite side decreases the angle.
For item 2, the triangles are ADB and CDB.
