Answer:
- If you score a 0% on your exam, you get 53.9% as your overall grade
- If you score 100% on your exam, you get 83.9% as your overall grade
====================================================
Explanation:
Your final is worth 30% of your grade, so the other 70% is what you've already done so far
The expression below
0.30x + 0.70*0.77
represents what your final grade would be in decimal form. We multiply the weights 0.30 and 0.70 with each of their corresponding grade value.
The x represents the decimal form of the final exam score.
------------
Let's say you get a 0% on the final. That would mean x = 0 and
0.30x + 0.70*0.77
0.30*0 + 0.70*0.77
0.539
So you'd end up with a 53.9% as the overall grade.
------------
Now let's say you get 100% on the final. We plug in x = 1 since it's the decimal form of 100%
So,
0.30x + 0.70*0.77
0.30*1 + 0.70*0.77
0.839
You would end up with a 83.9% as the overall grade.
Answer:
2 × (3 + 7 - 9) = (1 + 5) - (8 - 4)
Step-by-step explanation:
2 × (3 + 7 - 9) = (1 + 5) - (8 - 4)
Verification
2 × (10 - 9) = 6 - 4
2 × 1 = 2
2 = 2
Answer:
An 99% confidence interval of the given proportion
(0.355 , 0.385)
Step-by-step explanation:
Given sample size n= 900
the number of successes in the sample is x=333
The proportion P = 
Q = 1-P =1 - 0.37 = 0.63
<u>Confidence interval</u>:-
99% of confidence interval zα = 2.93
(0.37 - 0.015 , 0.37 + 0.015)
(0.355 , 0.385)
<u>Conclusion</u>:-
<u>An 99% Confidence interval (0.355 , 0.385)</u>
Rebecca payed $35 for the video game, simple math.
He lived 9 months in Portugal and 5 months in Brazil. This is because 130*9 + 150*5 = 1920.
