You need to find out how many problems Carl can do in a minute (unit rate), which is 20/55 or .36363636363. If you multiply it by 75 mins, you get 27.27, so the answer would be 27.
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:
7.5h+10=6.25(h+3)
Step-by-step explanation:
...........................................................
Obtuse: b^2 + c^2 > a^2
Right: b^2 + c^2 = a^2
Acute: b^2 + c^2 < a^2
A^2 + B^2 + c^2 - 2bc*cosA
As (A), is an Obtuse cos A is Negative say 2bccosA = - k then;
a^2 = b^2 + c^2 + k
a^2 > b^2 + c^2
So, your Answer would be (B)

The alpha level should always be set to 0.05.
The supplied statement;
How should you select the alpha() level when doing a significance test in practice,
⇒ Use a higher alpha when the consequences of wrongly rejecting the null hypothesis are more severe. Select alpha () = 0.05 in every situation since it is the best option. Use a smaller alpha when the consequences of wrongly rejecting the null hypothesis are more severe.
