Answer:
A) Mean = 135 Variance = 62 Standard Deviation = 8
Step-by-step explanation:
Given that :
Proportion (p) = 54%
Sample size (n) = 250
Using Normal approximation :
Mean = np
Mean = 250 * 0.54 = 135
Variance = npq ; q = 1 - p = 1 - 0.54 = 0.46
Variance = (250 * 0.54 * 0.46) = 62.1 = 62
Standard deviation = √variance = √62.1
Standard deviation = 7.8803553 = 8
To find Part A, take 3 2/3 and multiply that by 1 1/2 to get the amount of cherries. Then, you can simplify that answer if needed. For Part B, add 3 2/3 + x (number of pounds for red cherries) to get the answer to Part B. If you need help multiply for Part A, just let me know and I could help! :)
Answer:
All triangles add up to 180 degrees.
Step-by-step explanation:
Answer:
-18-6x=6+18x
-18-6=18x+6x
24x=-24
x=-1
Step-by-step explanation:
Divisibility by 2: the last digit must be even. The last digit of 15114 is 4, which is even, so 15114 is divisible by 2.
Divisibility by 3: the sum of the digits must be divisible by 3. The sum of the digits of 15114 is 12, which is divisible by 3, so 15114 is divisible by 3.
Divisibility by 5: the last digit must be 0 or 5. The last digit of 15114 is 4, so 15114 is not divisible by 5
Divisibility by 9: the sum of the digits must be divisible by 9. The sum of the digits of 15114 is 12, which is not divisible by 9, so 15114 is not divisible by 9.
