15/20 are French so 5/20 are English
Simplified that’s 1/4
Only applies if all the books are either English or French

Answer:
d) All of the above
Step-by-step explanation:
A one way analysis of variance (ANOVA) test, is used to test whether there's a significant difference in the mean of 2 or more population or datasets (minimum of 3 in most cases).
In a one way ANOVA the critical value of the test will be a value obtained from the F-distribution.
In a one way ANOVA, if the null hypothesis is rejected, it may still be possible that two or more of the population means are equal.
This one way test is an omnibus test, it only let us know 2 or more group means are statistically different without being specific. Since we mah have 3 or more groups, using post hoc analysis to check, it may still be possible it may still be possible that two or more of the population means are equal.
The degrees of freedom associated with the sum of squares for treatments is equal to one less than the number of populations.
Let's say we are comparing the means of k population. The degree of freedom would be = k - 1
The correct option here is (d).
All of the above
Answer:
I think it is A
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Answer:
The answer is Tonya's phone had the greater initial trade-in value.
Leo's phone decreases at an average rate slower than the trade in value of Tonya's phone.
Step-by-step explanation:
Given
Tonya
Leo
Solving (a): The phone with greater initial value
The initial value is when x = 0. So, we have:
From Leo's table
By comparison;
i.e.
<em>So: Tonya's had the greater initial trade-in value</em>
Solving (b): The phone with lesser rate
An exponential function is:
Where:
For Tonya
For Leo, we have:
So, the equation becomes:
and 
Solving , we have:
becomes
Divide both sides by 480
Take square roots
-- Leo's rate
By comparison; Leo's rate is slower i.e. 0.87 < 0.88
