Answer:
$3733
Step-by-step explanation:
Do 2600 * 1.075^5 = 3732.636248
3733 to nearest dollar
330 km/hr
Step-by-step explanation:
To find speed of the plane against the headwind;
600 km / 2 hours = 300 km/hr
Speed of plane with the wind in its back;
600 km / 5/3 hours = 600 * 3/5 = 360 km/hr
We can create a simultaneous equation from this data.
Assume the speed on pane in still air is x km/h
Assume the speed of wind is y km/h
Therefore;
x – y = 300
x + y = 360
Solving the simultaneous equation by elimination gives us;
x – y = 300
-
x + y = 360
=
-2y = - 60
y = 30
x = 330
The speed of the plane without wind is;
= 330 km/hr
The wind speed is;
= 30 km/hr

Answer:
The p-value of the test is 0.2.
Step-by-step explanation:
Using the alternative hypothesis that µ ≠ 531, Amy found a t-test statistic of 1.311.
Alternative hypothesis means that e have a two-tailed hypothesis test.
Sample 30 citizens. Amy found a t-test statistic of 1.311.What is the p-value of the test statistic?
Thus, we have a two-tailed test with 30 - 1 = 29 degrees of freedom and t = 1.311. So, using a t-distribution calculator, the p-value of the test is 0.2.
