Answer:
95,040 ways
Step-by-step explanation:
The first position has 12 choices
The second has 11 choices (since first is filled)
The third has 10 choices
The fourth has 9 choices
The fifth has 8 choices
So the number of ways they can make the ranking will be;
12 * 11 * 10 * 9 * 8 = 95,040 ways
The number of ways could the voters (student body) rank their first 5 choices is 792 ways.
Calculation of the number of ways:Since Last year at a certain high school, 12 students sought the nomination for president of the student body.
So, here
we use the combination here
[tex]= 12!\div 5!7!\\\\= 12\times 11\times 10\times 9\times 8\times 7!\div 5!7!\\\\= 12\times 11\times 10\times 9\times 8\div 5\times 4\times 3\times 2[/tex]
= 792 ways
Therefore, The number of ways could the voters (student body) rank their first 5 choices is 792 ways.

What percent of 16 is 50% of 50% of 48?
Answer:
150
Step-by-step explanation:
x %* 16 = 50% * 48
[tex]\frac{x}{100} = \frac{0.5 *48}{16} = \frac{24}{16} = \frac{6}{4} = \frac{3}{2} \\x = \frac{300}{2} = 150\\[/tex]
I guessed 50% is typed wrongly twice so I solved once with 50%
75% of 16 is equal to 50% of 50% of 48.
Percentage of 16 equivalent to 50% of 50% of 48 to be evaluate.
Percentage is the matter of composition per unit whole composition.
Let x% of 16 = 50% of 50% of 48
x/100 *16 = 1/2*1/2*48
x/100*16 = 12
x = 12/16 * 100
x = 75%
Thus, 75% of 16 is equal to 50% of 50% of 48.

selling them for $5 each pair. Find the minimum number of
gloves you have to sell in order to make a profit.
Answer:
You need to sell 6 gloves

Mrs. Peterson makes ceramic figurines. She recently made 25 figurines. Of those figurines, 16 are animals. What percent of the figurines are NOT animals?
Answer:
Depends on how many digits the question wants. If rounded, 38%. Or just 37%
Step-by-step explanation:
She made 25 in all.
16 of them are animal figures. The question is asking what percent is NOT animal figure, so we need to subtract 25 by 16. That gives us 9. To find the percent, we need to divide 9 by the whole, which is 24. 9/24=0.375
The answer is 37% or 37.5% (It depends on how many digits the question is asking for. Also try rounding (38%).

f(x) = 2x3 + 3x2 – 7x + 2
g(x) = 2x – 5
Find (f + g)(x).
Answer:
(f + g)(x) = 2x³ + 3x² - 5x - 3 ⇒ B
Step-by-step explanation:
Let us solve the question
∵ f(x) = 2x³ + 3x² -7x + 2
∵ g(x) = 2x - 5
→ (f + g)(x) means add f(x) and g(x)
∴ (f + g)(x) = (2x³ + 3x² - 7x + 2) + (2x - 5)
→ Add the like terms
∵ (f + g)(x) = 2x³ + 3x² + (-7x + 2x) + (2 - 5)
∴ (f + g)(x) = 2x³ + 3x³ + (-5x) + (-3)
→ Remember that (+)(-) = (-)
∵ 2x³ + 3x³ + (-5x) + (-3) = 2x³ + 3x² - 5x - 3
∴ (f + g)(x) = 2x³ + 3x² - 5x - 3

Evaluate the double integral. 4y2 dA, D is the triangular region with vertices (0, 1), (1, 2), (4, 1)
Answer:
44/3
Step-by-step explanation:
Let A be the line joining the vertices (0, 1) and (1,2) while B be the equation of the line joining (1, 2) and (4, 1).
The equation of a line joining points [tex](x_1,y_1) \ and\ (x_2,y_2)\ is:\\\\[/tex]
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)[/tex]
The equation of line A joining (0, 1) and (1,2) is:
[tex]y-1=\frac{2-1}{1-0} (x-0)\\\\y-1=x\\\\x=y-1[/tex]
The equation of line D joining (1, 2) and (4,1) is:
[tex]y-2=\frac{1-2}{4-1} (x-1)\\\\y-2=-\frac{1}{3} (x-1)\\\\3y-6=-x+1\\\\x=-3y+7[/tex]
Therefore the change in y is: 1 ≤ y ≤ 2, while change in x is: y-1 ≤ x ≤ -3y + 7. Hence the double integral is:
[tex]\int\limits^2_1\int\limits^{-3y+7}_{y-1} {4y^2} \, dx dy\\\\=4\int\limits^2_1\int\limits^{-3y+7}_{y-1} {y^2} \, dx dy\\\\=4\int\limits^2_1y^2dy[x]^{-3y+7}_{y-1} \\\\=4\int\limits^2_1y^2dy(-3y+7-(y-1))\\\\=4\int\limits^2_1y^2dy(-4y+8)\\\\=4\int\limits^2_1(-4y^3+8y^2)dy\\\\=4[-y^4+\frac{8}{3}y^3 ]^2_1\\\\=4(\frac{11}{3} )\\\\=\frac{44}{3 }[/tex]
To answer this question, we need, first get the equations for the lines that enclosed the surface, and integrate according to the limits obtained from these equations give.
The solution is:
A = 44/3 square units
Let´s call points:
P ( 0 , 1 ) Q ( 1 , 2 ) and R ( 4 , 1 )
The equation for the line between, P and R is:
y = 1
The equation for the line between, P and Q is:
Slope-intercept equation is y = m×x + b
The slope m₁ = ( 2 - 1 ) / ( 1 - 0 ) m₁ = 1
and the line passes over the point x = 0 y = 1 ; then
1 = 0 +b b = 1
y = x + 1 ⇒ x = y - 1
The equation for the line between Q and R is:
m₂ = ( 1 - 2 ) / ( 4 - 1) m₂ = - 1/3
y = ( -1/3)× x + b
when x = 1 y = 2
2 = ( - 1/3)×(1) + b
2 + 1/3 = b
b = 7/3
y = - (x/3) + 7/3 ⇒ x = 7 - 3×y
The double integral becomes:
A = 4×∫∫ y² dx dy ⇒ A = 4 ×∫₁² y²dy ∫dx | (y - 1 ) y ( 7 - 3y)
A = 4×∫₁² y²dy × x | ( y - 1 ) y ( 7 - 3y)
A = 4 ×∫₁² y²dy × [ 7 - 3×y - ( y - 1 )]
A = 4 ×∫₁² y²dy × (8 - 4×y ) ⇒ A = 4 ×∫₁² (8×y² - 4×y³ ) dy
A = 4 × [ (8/3)×y³ - y⁴ | ₁²
A = 4 × [ 64/3 - 16 - (8/3) + 1 ]
A = 4 × ( 56/3 - 15 )
A = 4 × ( 56 - 45 /3)
A = 4 × 11/3
A = 44/3 square units
