Answer:
99.7% data lies between 13 to 43
Step-by-step explanation:
Mean:
Standard deviation :
68% of data lies between to
95% of the data lies between to
99.7% data lies between to
We are supposed to find 99.7 of the data will lie between which values
99.7% data lies between to
99.7% data lies between 13 to 43
Hence 99.7% data lies between 13 to 43
There are 2.5 tsp vanilla needed for 5 cups of flour. I solved this by putting the given info into a ratio- cups of flour/tsp. vanilla. Then, i put in the given information and cross multiplied to solve for x. I hope this helped you!! :))
If you would like to solve the equation 1 2/5 * x = 7, you can calculate this using the following steps:
1 2/5 * x = 7
7/5 * x = 7 /*5/7
x = 7 * 5/7
x = 5
The correct result would be 5.
Answer:
probability (x ≤2) = 0.64
Step-by-step explanation:
P(2 or fewer) = probability of 2 or fewer
probability of (2 or fewer) = probability (x ≤2)
probability of (2 or fewer) = probability when x is 0 + probability when x is 1 + probability when x is 2
probability of (2 or fewer) = probability (x =0) + probability of (x =1 ) + probability (x= 2)
probability of (x=0) = 0.09
probability of (x=1) = 0.26
probability of (x =2) = 0.29
probability of (2 or fewer) = 0.09 + 0.26 + 0.29 = 0.64
probability (2 or fewer) = probability (x ≤2) = 0.64
Let W = width of package
Let H = height of package
Let L = length of package
The perimeter cab be one of the following:
P = 2(L + W), or
P = 2(L + H)
The perimeter of the cross section cannot exceed 108 in.
When the width is 10 in, then
2(L + 10) <= 108
L + 10 <= 54
L <= 44 in
When the height is 15 in, then
2(L + 15) <= 108
L + 15 <= 54
L <= 39 in
To satisfy both of these conditions requires that L <= 39 in.
Answer: 39 inches
