Answer:
5.10 people
Step-by-step explanation:
Calculation to Find the standard deviation for the number of people with the genetic mutation
Using this formula
Standard deviation = √ ( n * p * q)
Where,
n = 400
p = .07
q = 100%-7% = 93% or .93
Let plug in the formula
Standard deviation =√400*07*.93
Standard deviation =√26.04
Standard deviation = 5.10 people
Therefore the standard deviation for the number of people with the genetic mutation is 5.10 people.
Answer:36 divided by 3x is part a and 7 is part b
Step-by-step explanation:
numerator = top part of the fraction
denominator = bottom part of the fraction
* means multiply
a.
you can only add the numerator when the denominator is the same
cant add the denominator
denominator has to be the same
1/5 = 4/20
4/20 + 7/20 = 11/20
b.
1 7/8 = 15/8
3/4 ÷ 15/8 =
3/4 * 8/15 =
24/60 = divide both top and bottom by 12 =
2/5
Answer: Salid should get $38.75 of change.
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
- <em>Quantity of window trim bought: 35 feet
</em>
- <em>Cost per feet: $1.75
</em>
- <em>Amount paid: $100
</em>
First, we have to calculate the total cost, by multiplying the Quantity of window trim bought (35) by the price per feet (1.75)
35 x 1.75 = $61.75
Finally, to calculate the change that Salid should get, we have to subtract the total cost (61.75) to the amount paid (100)
100-61.75=$38.75
It doesn't give the entire question, Do they want to know how many pieces were in the total cake? If so, I think it would be 384. You subtract the 3 pieces that Mindy ate and that leaves 96 that Tony had which was supposed to be 1/4 of the cake. Dividing the cake into 4 sections of 96 and multiplying would give you 384.
If they want to know how many slices of cake were left after Tony ate the fourth (96 slices), it would be 288
