Answer:
=110.8 percent
Step-by-step explanation:
We can use this formula to find the percent increase
percent increase = (new - original)/ original * 100
new = 363,844,490
original =172,602,624
Substitute these values in
percent increase = (363,844,490 - 172,602,624)/ 172,602,624 * 100
percent increase = 191241866/172602624 *100
= 1.107989332
=110.8 percent
Answer:
532
Step-by-step explanation:
The score that represents the top 20% = A score = 80%
Z score for 80% percentile = 0.842
We solve using the z score formula
z = (x-μ)/σ, where
x is the raw score = ??
μ is the population mean = 490
and σ is the population standard deviation = 50
Hence:
0.842 = x - 490/50
Cross Multiply
0.842 × 50 = x - 490
x = 0.842 × 50 + 490
x = 42.1 + 490
x = 532.1
Approximately = 532
Therefore, the test score = 532

Your answer is in
green and also in yellow.
The area is 24 square inches. So its dimensions in inches
must be factor-pairs of 24 .
Those are
1 x 24
2 x 12
3 x 8
or
4 x 6 .
