2* 100 + 2 * 65 = 330 perimeter
100 * 65 = 6,500 area
2*90 + 2*75 = 330 perimeter
90 * 75 = 6,750 area
Answer:
The two sample t-test
Step-by-step explanation:
The appropriate test for thus is the two sample t test which is also known as the independent t test. This tests aims at determined whether there is a statistically significant difference between the means in two unrelated groups which in this context are a random sample with one type of preservative and another sample with another type of preservatives.
With this test, the researcher is able to compare the mean shelf lives of the bananas treated with the two different preservatives... The null hypothesis equalises the two means of the sample while the alternative does otherwise.
Answer:
Surface area of cube =6× l^2 (where l is the side of cube)
Therefire 6×9^2=6×81
=486in^2
Answer:
D. $39,706.20
Step-by-step explanation:
In this problem, you are subtracting 14%. A way you could do this is buy finding 14% of $46,170.00, then subtracting that from itself. Or instead, you could find 86%. This works because its like your subtracting 14% from the whole 100%. so 100 - 14 = 86.
Method 1:
$46,170.00 x 0.14 = 6463.8
$46,170.00 - 6463.8 = 39706.2
Method 2:
100 - 14 = 86
$46,170.00 x 0.86 = 39706.2
either way the answer is still correct. i hope this make sense and that it helps you!
