Answer:
No. of gonjas = 52
No. of more nzemas than fantes = 78
Step-by-step explanation:
Total no. of people = 520
No. of fantes = 
× 520
No. of fantes = 156
No. of ewes = 
× 520 = 130
No. of nzemas = 
× 520 = 78
No. of gas = 
× 520 = 104
No. of gonjas = 520 - (156 + 130 + 78 + 104) = 52
No. of fantes = 156
No. of nzemas = 78
No. of more nzemas than fantes = 156 - 78 = 78
Pie chart of the following problem is shown below.
Consider c as the cost of the widget so that our given equation is
c = 0.1w^2 + 20w
Take the derivate of the equation.
d/dt (c = 0.1w^2 + 20w)
dc/dt = 0.2w + 20
Given dc/dt = $16000 per month, the number of widgets would contain:
16000 = 0.2w + 20
-0.2w = 20 - 16000
-0.2w = -15980
w = 79900 widgets
Z = (x - mean) / SD = (79 - 70) / 3 = 3
<span>P (Z > 3)? = 1 - F (z) = 1 - F (3) = 0.00135</span>
"Per" means "divided by", so "cost per ounce" means "cost"/"ounces".
The difference in cost per ounce is
.. (1.14/12) -(1.28/16) = .095 -.08 = 0.015
Brand X costs 1.5¢ more per ounce than Brand Y.
X + 1
Combine like terms, so terms with x go together and terms without an x go together
So 2x - x = x
3 - 2 = 1
That's as simplified as it can be
