Answer:
17.5
Step-by-step explanation:
Since the 6 behind the number being rounded is 5 or above, then you round up. If it was 4 or below you wouldn't.
Hope it helps!
Answer:
The probability that sample mean differ the true greater than 2.1 will be 2.8070 %
Step-by-step explanation:
Given:
Sample mean =46 dollars
standard deviation=8
n=53
To Find :
Probability that sample mean would differ from true mean by greater than 2.1
Solution;
<em>This sample distribution mean problem,</em>
so for that
calculate Z- value
Z=(sample mean - true mean)/(standard deviation/Sqrt(n))
Z=-2.1/(8/Sqrt(53))
Z=-2.1*Sqrt(53)/8
Z=-1.91102
Now for P(X≥2.1)=P(Z≥-1.91102)
Using Z-table,
For Z=-1.91
P(X>2.1)=0.02807
The area of a regular octagon is given by:
A = (4) * (L) * (ap)
Where,
L: side
ap: apotema
Substituting values we have:
A = (4) * (19) * (16)
A = 1216 square inches
Answer:
The area of a regular octagon with an apothem 16 inches long and a side 19 inches long is:
A = 1216 square inches
Answer:
The correct answer is C. 47 3/4 oz.
Step-by-step explanation:
Since Ricki caught ten fish, and the weights of the fish were 3 2/4 oz one of them, 4 1/4 oz three of them, 4 3/4 oz two of them, and 5 2/4 oz four of them To determine their total weight, the following calculation must be performed:
3 2/4 + (4 1/4 x 3) + (4 3/4 x 2) + (5 2/4 x 4) = X
3 2/4 + 12 3/4 + 9 2/4 + 22 = X
46 7/4 = X
47 3/4 = X
Therefore, the total weight of the fish was 47 3/4 oz.
First you would have to multiply $18 (The cost for each month) and 12 (the number of months in a year) and the answer would be 216
So she deducts 216 a year, so the answer would have to be negative
The final answer is -216
