Using the midpoint formula directly from the topic meaning
so
6x^2 -9x -2 just add common variables
Answer:
Step-by-step explanation:
Let the number of weeks be x
<u>Then Kendal's CD's</u>
<u>Raymond's CD's</u>
<u>Time when they have equal CD's</u>
- 39 + x = 15 + 3x
- 3x - x = 39 - 15
- 2x = 14
- x = 7 weeks
The t-value given the following: hypothesis test on population mean is -2.
<h3>What is T- value ?</h3>
T-value in statistics can be defined as the ratio of the difference between the mean of the two sample data and the variation in the sample data
It is given by
Here in the question all the values are given
x= 33; μ = 35; s = 5; n = 25.
Substituting the values to determine t
Therefore the t-value given the following: hypothesis test on population mean is -2.
