Step-by-step explanation:
24% of 800 ➡ 800 ÷ 100 × 24 = 192
75% of 1000 ➡ 1000 ÷ 100 × 75 = 750
4:4 and 5:5 are <span> two ratios that are equivalent to 1:1</span>
Answer:
89.84375
Step-by-step explanation:
Given that on a finance exam, 15 accounting majors had an average grade of 90. On the same exam, 7 marketing majors averaged 85, and 10 finance majors averaged 93.
To find weighted mean.
Here weights can be considered as number of majors in each subject
Weighted total = 1350+595+930 = 2875
Weighted mean = weighted total/total students
The slope of the tangent line to at is given by the derivative of at that point:
Factorize the numerator:
We have approaching -1; in particular, this means , so that
Then
and the tangent line's equation is
The answer is C. Just divide all of the fractions and use the decimals to see which is bigger/smaller.
