Answer:
Since the null hypothesis is true, finding the significance is a type I error.
The probability of the year I error = level of significance = 0.05.
so, the number of tests that will be incorrectly found significant is computed as follow: 0.05 * 100 = 5
Therefore, 5 tests will be incorrectly found significant given that the null hypothesis is true.
Answer:
30/552
Step-by-step explanation:
In order to solve this problem you need to multiply the probability of getting grape for the first gumball with the probability of getting grape for the second gumball. Since there are 6 grape gumballs and a total of 24 gumballs (6*4). Then the probability of getting grape for the firs one is
Now there are only 5 grape gumballs available and one less in the total supply, therefore the probability of getting grape in the second try is
Finally we multiply them together to find the probability of getting two grapes in a row.
= 
1/2+1/3+1/6=3/6+2/6+1/6=6/6=1
By putting them all at the same denominator, you can add them all together.
then you have to divide it by 3 for the three.
1/3 is the average.
Answer:
A. 10 bricks
B. 4 pounds
Step-by-step explanation:
Water = 39 pounds
brick dust = 48 pounds
Total mixture = water + brick dust
= 39 + 48
= 87 pounds
She spills 13 pounds of the mixture while stirring
Remaining mixture = Total mixture - Spillage
= 87 pounds - 13 pounds
= 74 pounds
The mixture is then poured into small dirt holes to make bricks. Each brick requires 7 pounds of mixture
Number of bricks made = Remaining mixture / pounds per brick
= 74 pounds / 7 pounds
= 10 bricks remaining 4 pounds of the mixture
A. What is the greatest number of bricks Lynn can make?
10 bricks
B. How many pounds of mixture will be washed out of the bucket if Lynn makes the greatest number of bricks?
4 pounds
Answer: 16
Step-by-step explanation:
if we were to list all the factors of 64 and 144
64= 1,2,4,8,8,16,32,64
144= 1,2,3,4,6,8,9,12,12,16,18,24,36,48,72,144
therefore the GCF of 64 and 144 is 16
