Answer:
The overall score is 75.6
Letter grade is C
Step-by-step explanation:
The question has missing details (See comment section for complete question).
From the complete question, we have:
<u>Proportion:</u>
Scores
Solving (a): The overall score
To do this, we simply calculate the mean of the given data.
The mean is calculated by multiplying each proportion by the scores..
So, we have:
Solving (b): The letter grade
From the question, we have:
The overall score falls in the following category:
Because:
<em>Hence, the letter grade is C</em>
Answer:
a. y= -5/2x -4
Step-by-step explanation:
An equation that is perpendicular to another equation must have the opposite slope. In other words, the perpendicular equation will be the opposite sign & the reciprocal of the equation it is perpendicular to. In this case, the perpendicular slope is -5/2x. Therefore, the only answer possible is a.
Answer:
Two zeros are 17 and -5
Step-by-step explanation:
Given:
f(x) = x² - 12x - 85
Find:
Zeros of the function
Computation:
f(x) = x² - 12x - 85
f(x) = x² - (17 - 5)x - 85
f(x) = x² - 17x + 5x - 85
f(x) = x(x - 17) + 5(x - 17)
f(x) = (x - 17) (x + 5)
So,
x - 17 = 0 , x + 5 = 0
So,
x = 17 , x = -5
Two zeros are 17 and -5
Answer:
m∠1 = 64°
m∠2 = 116°
Step-by-step explanation:
Since the 2 angles are on a line, that means that when added, they equal 180°
Combine like terms:
2x + (x + <u>84</u>) = 180°
3x + <u>84</u> = 180°
Now, subtract to have 3x one side; then divide:
3x = 96
<em>x = 32</em>
Now, we can find the angle measures.
m∠1 = 2 (32) m∠2 = (32) + 84
m∠1 = 64° m∠2 = 116°
Hello!
What you would want to do first is to multiply 8 by 16. If your rate is $8 an hour and you work 16 hours, you'll need to multiply 8 by 16. Once you've done that you should now have $128. Now if you stick with your payment rate for 11 weeks, then you'll need to multiply 128 by 11. After you've done that you will have your answer of $1408
I hope this helps!
