Answer:
7,260 ways
Step-by-step explanation:
Here, we are told that the president must be a senior and the secretary must be a freshman.
Now for the post of President, we have 15 choices to pick from
For the post of secretary, we have 11 choices to pick from
Now the last position, the vice president
Firstly , we have 14 seniors( 1 already president), 10 freshmen(1 already secretary) , 6 sophomores and 13 juniors
So the total number of choices will be;
14 + 10 + 7 + 13 = 44
So the number of ways will be;
44 * 15 * 11 = 7,260 ways
Use the Rational Zero Theorem to list all possible rational zeros for the given function.
f(x) = 9x^4 - x^3 + 4x^2 - 5x - 6.
Which of the following is the complete list of possible zeros of the given function?
a. ±1, ±3, ±2, ±1/3, ±2/3
b. ±1, ±3, ±2/3, ±1/9, ±2/9
c. ±1, ±3, ±2, ±6, ±1/3, ±2/3, ±1/9, ±2/9
d. The function has no rational zeros.
which function is the inverse of f(x) equals negative 5X -4
Answer:
f inverse x = -x+4/5
Step-by-step explanation:
Answer:
f^-1(x) = -1/5 x - 4/5
Step-by-step explanation:
f(x) = -5x - 4
Replace f(x) with y.
y = -5x - 4
Switch x and y.
x = -5y - 4
Solve for y.
5y = -x - 4
y = -1/5 x - 4/5
Replace y with f^-1(x).
f^-1(x) = -1/5 x - 4/5
Please help, "What if you magnified the image of a cluster fly (9 millimeters) by 9*10 exponent 3? What would the length appear to be?" Please hElP
Answer:
9000
Step-by-step explanation:
This is written in scientific notation. When you have a positive exponent (x³), You move the decimal point to the right as many times as the exponent says. Since the exponent is +3, move the decimal to the right 3 spaces:
[tex]9.0(0)\\\\90.0(1)\\\\900.0(2)\\\\9000.0(3)[/tex]
So:
[tex]9*10^3=9000[/tex]
:Done
*Magnifying means that the image will be bigger. So, the new number has to be greater than 9. Since 9000>9, this is true.
This applet illustrates 95% confidence intervals for samples from a normal distribution with known variance. (a) When taking 100 samples of size 30 or greater from a population, exactly 95 of them will create a confidence interval that contains the true population mean. True False (b) Which statement is the correct interpretation of the confidence interval in this illustration?
Answer:
Step-by-step explanation:
When taking 100 samples of size 30 or greater from a population, exactly 95 of them will create a confidence interval that contains the true population mean. True or false?
This statement is false, or better still, ambiguous. 100 samples of size 30 (or greater) each, means 300 total and it can't be just 95 of them that will contain the true population mean.

(01.02 MC)Which statement best explains the value of 18 − (−5)? The additive inverse of −5 is +5, so 18 − (−5) = 23. The additive inverse of −5 is −5, so 18 − (−5) = 23. The additive inverse of −5 is −5, so 18 − (−5) = 13. The additive inverse of −5 is +5, so 18 − (−5) = 13.
Hey there! I'm happy to help!
The additive inverse of a number is one that has its sign switched. If you put a - before a number, the sign switches. We put a - before -5, so its sign switches. -5's additive inverse is 5, so this 18+5, giving us 23.
The additive inverse of -5 is +5, so 18 - (-5)=23.

Stuco wants to start a new project to help with trash removal. They need $15 to buy supplies at the local landfill and they charge 75 per pound.
How can you use this info to assess the possible cost of the service project? If the Senior Class collects 235 pounds of trash, what is the cost
going to be?
Answer:
$17,640
Step-by-step explanation:
Stuco wants to start a new project to help with trash removal. They need $15 to buy supplies at the local landfill and they charge 75 per pound. If the Senior Class collects 235 pounds of trash, the cost is going to be $17,640.
235 ⋅ 75 = 17,625
17,625 + 15 = 17,640
Therefore, the answer is $17,640.

James had 42 dollars. He bought his sister a gift that costs x dollars. How much money does james have now, in terms of x
Answer:
42-x = James' money now
Step-by-step explanation:
James has "42-x dollars" after purchasing a gift for his sister.
Expression for money left to James to be determine if he spend x dollars from $42.
Arithmetic is branch of math that teach how a word statement can be transform to mathematical expression.
Here, James spend x dollars to bought his sister a gift from $42.
Now, James has only 42-x dollars left in his pocket.
Thus, James has '42-x' dollars after purchasing a gift for his sister.

Landon babysits and works part time at the water park over the summer. One week, he babysat for 3 hours and worked at the water park for 10 hours and made $109. The next week he babysat for 8 hours and worked at the water park for 12 hours and made $177. How much does Landon make per hour at each job?
Answer:
Babysitting =$8.7
Water park =$8.7
Step-by-step explanation:
In 1 week
Babysitting =3 hrs
Water park = 10 hrs
Total =$ 109
In week 2
Babysitting = 8 hrs
Water park = 12 hrs
Total= $ 177
Both weeks
Babysitting =11 hrs
Water park =22 hrs
Total=$286
33 hrs = $ 286
11 hrs =?
11×286÷33=$95.3
33 hrs = $286
22 hrs = ?
22×286÷33=190.7
Babysitting she got $95.3 in both weeks
Water park she got $190.7(rounded offf)in both weeks
11 hrs = $95.3
1 hr = ?
1×95.3÷11=8.7 (rounded off )
22 hrs = $ 190.7
1 hr = ?
1×190.7÷22= 8.7( rounded off)
[tex]\frac{(2xy^2)^5}{(4x^2y)^2 (xy^2)}[/tex]
Please solve this and also mention the steps
Answer:
2 y^6
Step-by-step explanation:
Simplify the following:
(2 x y^2)^5/((4 x^2 y)^2 x y^2)
Hint: | Distribute exponents over products in (4 x^2 y)^2.
Multiply each exponent in 4 x^2 y by 2:
(2 x y^2)^5/(4^2 x^(2×2) y^2 x y^2)
Hint: | Multiply 2 and 2 together.
2×2 = 4:
(2 x y^2)^5/(4^2 x^4 y^2 x y^2)
Hint: | Evaluate 4^2.
4^2 = 16:
(2 x y^2)^5/(16 x^4 y^2 x y^2)
Hint: | Distribute exponents over products in (2 x y^2)^5.
Multiply each exponent in 2 x y^2 by 5:
(2^5 x^5 y^(5×2))/(16 x^4 y^2 x y^2)
Hint: | Multiply 5 and 2 together.
5×2 = 10:
(2^5 x^5 y^10)/(16 x^4 y^2 x y^2)
Hint: | Compute 2^5 by repeated squaring. For example a^7 = a a^6 = a (a^3)^2 = a (a a^2)^2.
2^5 = 2×2^4 = 2 (2^2)^2:
(2 (2^2)^2 x^5 y^10)/(16 x^4 y^2 x y^2)
Hint: | Evaluate 2^2.
2^2 = 4:
(2×4^2 x^5 y^10)/(16 x^4 y^2 x y^2)
Hint: | Evaluate 4^2.
4^2 = 16:
(2×16 x^5 y^10)/(16 x^4 y^2 x y^2)
Hint: | Multiply 2 and 16 together.
2×16 = 32:
(32 x^5 y^10)/(16 x^4 y^2 x y^2)
Hint: | In (32 x^5 y^10)/(16 x^4 y^2 x y^2), divide 32 in the numerator by 16 in the denominator.
32/16 = (16×2)/16 = 2:
(2 x^5 y^10)/(x^4 y^2 x y^2)
Hint: | For all exponents, a^n a^m = a^(n + m). Apply this to (2 x^5 y^10)/(x^4 y^2 x y^2).
Combine powers. (2 x^5 y^10)/(x^4 y^2 x y^2) = 2 x^(5 - 1 - 4) y^(10 - 2 - 2):
2 x^(5 - 1 - 4) y^(10 - 2 - 2)
Hint: | Evaluate 5 - 1 - 4.
5 - 1 - 4 = 0:
2 x^0 y^(10 - 2 - 2)
Hint: | Evaluate 10 - 2 - 2.
10 - 2 - 2 = 6:
2 x^0 y^6
Hint: | Any nonzero expression to the zero power is one.
x^0 = 1:
2×1 y^6
Hint: | Simplify the expression.
Write 2×1 y^6 as 2 y^6:

A large pizza is $18 and a small pizza is $12. Each topping is.50.
How my would it cost for a large pizza with 5 toppings> *
Answer:
$20.50
Step-by-step explanation:
The pizza itself is $18. If you wanted 5 toppings you would do .50 multiplied by 5. That would give you a total of $2.50 for the 5 toppings. 18 plus 2.50 is 20.50.
Answer:
A large pizza with 5 toppings will be $20.50
A small pizza with 5 toppings will be $14.50
5 toppings would cost $2.50
Step-by-step explanation:
.50x5=2.50
18.00x2.50=20.50
12.00+2.50=14.50

2a + 4c = 38.00 solve for c
Answer:
c = 19/2 - 1/2a
Step-by-step explanation:
Step 1: Write equation
2a + 4c = 38.00
Step 2: Solve for c
Subtract 2a on both sides: 4c = 38 - 2a
Divide both sides by 4: c = 19/2 - 1/2a
Step-by-step explanation:
2 (a+2c)=38
a+2c=19
c=(19-a)/2

9. If LK MK, LK = 7x - 10, KN = x + 3, MN = 9x - 1), and KJ = 28, find L.
Answer:LJ = 18 + 28 = 46
Step-by-step explanation:
Suppose J, K, L, M, N are points on the same line.
MK = MN + (-KN) = MN - KN = 9x - 11 - x - 3 = 8x - 14
Since LK = MK and LK = 7x - 10, then
7x - 10 = 8x - 14
8x - 7x = -10 + 14
x = 4
LJ = MK + KJ
MK = LK = 7x - 10 = 7(4) - 10 = 28 - 10 = 18
LJ = 18 + 28 = 46
