Answer:
3.8
Step-by-step explanation:
Hey! Let's start by assuming that these are all normal courses, and that <u>GPA is given by the following scale:</u>
A - 4.0
B - 3.0
C - 2.0
D - 1.0
F - 0.0
That said, this question really just involves calculating the averages.
To find the average, we add all the values together and divide the sum by the total number of values.
<u>Therefore, our expression would look like:</u>
(4.0 + 4.0 + 4.0 + 4.0 + 3.0)/5
This is because there are 5 total values.
Simplify:
19/5
3.8
This means your GPA would be 3.8
Answer:
Option A) is correct.
Step-by-step explanation:
The final cost of a sale item is determined by multiplying the price on the tag by 75%.
So. if the final cost is represented by $F and the price on the tag is $t, then the relation between F and t will be
F = 0.75t.
This relation is linear since the ratio of the change in the final cost compared to the rate of change in the price tag is constant.
Therefore, option A) is correct. (Answer)
I got you fam it's 112! : )
Answer:
Step-by-step explanation:
The hypothesis is written as follows
For the null hypothesis,
µd ≤ 10
For the alternative hypothesis,
µ > 10
This is a right tailed test
Since no population standard deviation is given, the distribution is a student's t.
Since n = 97
Degrees of freedom, df = n - 1 = 97 - 1 = 96
t = (x - µ)/(s/√n)
Where
x = sample mean = 8.9
µ = population mean = 10
s = samples standard deviation = 3.6
t = (8.9 - 10)/(3.6/√97) = - 3
We would determine the p value using the t test calculator. It becomes
p = 0.00172
Since alpha, 0.01 > than the p value, 0.00172, then we would reject the null hypothesis. Therefore, At a 1% level of significance, there is enough evidence that the data do not support the vendor’s claim.
I think the answer is 90 degrees
