Step by step explanation:
A student may participate in football or golf. About 13% of the student body at a high school participates in football. About 8% plays golf. What is the probability that a student chosen at random participates in either football or golf?
5%
104%
13%
21%
Answer:
21%
Step-by-step explanation:
The sum of the 13% who play football and the 8% who play golf would be 21%
.13 + .08 = .21

4/5 N= 2/3. N = ?
2/15
5/6
1 1/5
1 7/15
Answer:
N = 5/6
Step-by-step explanation:
4/5 N= 2/3. Find N (solve for N).
Isolate N. To do this, multiply both sides of the equation by (5/4):
(5/4)(4/5)N= (5/4)(2/3)
becomes N = 10/12, or N = 5/6.
Sue and Bill share a 16-ounce box of cereal. By the end of the week, Sue has eaten 5 8 of the box, and Bill has eaten 1 4 of the box of cereal. How many ounces are left in the box?
Answer: 2 ounce
Step-by-step explanation:
Given
16 ounce of the box is shared by Sue and Bill
Sue has eaten [tex]\frac{5}{8}[/tex] of the box
Bill has eaten [tex]\frac{1}{4}[/tex] of the box
total cereal eaten by them is
[tex]\Rightarrow \dfrac{5}{8}+\dfrac{1}{4}=\dfrac{5}{8}+\dfrac{2}{8}\\\\\Rightarrow \dfrac{7}{8}[/tex]
So, they have eaten this much of the box. Amount left in the box is
[tex]\Rightarrow 1-\dfrac{7}{8}\\\\\Rightarrow \dfrac{1}{8}[/tex]
In ounce it is
[tex]\Rightarrow 16\times \dfrac{1}{8}\\\\\Rightarrow 2\ \text{ounce}[/tex]
On a trip, Gavin bought a ping-pong racket for $33. With the tax, he paid $36.96. What is the tax rate, in percent?
Answer:
12%
Step-by-step explanation:
Tax = 36.96 - 33 = 3.96
Tax rate = 3.96/33 * 100 = 12%
If the circumference of a circle is 10pi inches what is the area, in square inches of the circle?
A 10pi
B 25pi
C 50pi
D 100pi
Answer:
C 50pi
Step-by-step explanation:
Now, 2pi*r = 10pi. Thus 2r = 10. Thus, as the diameter of the circle is the diagonal of the square, the side of the square = = --> Area = = 50 sq. units

Allie went to space camp and her final project was a rocket launch. She is being graded on the maximum height that her rocket reaches. Here is her grading rubric: For an A>30 ft high, for a B >25 ft high, for a C>20 ft high, for a D>15 ft high, anything less than 15 ft high Allie would receive an F. What grade did Allie receive? Here is a function of the path that Allie's rocket took
Answer:
Step-by-step explanation:
Given formula: y= -4x^2+24x+2
max height given by the derivative of above formula, being equal to zero
0 = -8t +24
8t = 24
t = 3
at 3.0000000 seconds there will be a max in the rockets height ( that was nice of who ever figured out this formula to make it so easy )
y = height
y= -4*3^2+24*3+2
h = -36 +72 +2
h = 38 feet? we were not told if the formula is in feet. ( assume that it is , but double check it)
Nice ! so Allie gets an A :) A for Awesome Allie, :DDDD

To make purple plum paint, the paint store mixes blue and red paint in a ration of 8:5 if a customer needs 65 gallon of paint how many gallons blue and red paint needs to go in the mix
Answer:
Number of gallons of blue paint = 40 gallons
Number of gallons of red paint = 25 gallons
Step-by-step explanation:
We are given the ratio:
Blue paint : Red paint =
8 : 5
Sum of proportion = 8 + 5 = 13
If the customer need 65 gallons of paint,
a) Number of gallons of blue paint needed =
8/13 × 65 gallons = 40 gallons
b) Number of gallons of red paint needed =
5/13 × 65 gallons = 25 gallons
Therefore:
Number of gallons of blue paint = 40 gallons
Number of gallons of red paint = 25 gallons

(5-2)/(x-1) = 3
x=-2
Answer:
D. 0
Step-by-step explanation:
the slope of the line is negative reciprocal to the slope of the other line 1/3=> -3
(5 - 2)/(x - 1) = -3
=> 3/(x - 1) = -3
=> x - 1 = -1
=> x = 0

1. F(-5)=2x+1
2. F(-4)=2x+1
3. F(1)=2x+1
4. F(3)=2x+1
5. F(5)=2x+1
Answer:
1. F(-5) = -9
2. F(-4) = -7
3. F(1) = 3
4. F(3) = 7
5. F(5) = 11
Step-by-step explanation:
For each problem, F(x) is replaced with x.
An example is F(-5) = 2x + 1 (your first question).
To solve this, you replace x with -5.
This creates F(-5) = 2(-5) +1
We just simplify by multiplying -5 by 2 and then adding 1.
-5 times 2 equals -10. -10 plus 1 equals -9.
Your final answer for this example problem would be F(-5) = -9.
This applies to all problems as such -- F(x) where x inside the parentheses replaces all x values in the equation.

Show that p(x) is divisible by q(x) in each of the
following cases.
Answer:
See Below.
Step-by-step explanation:
By the Factor Theorem, if we divide q(x) into p(x) and the resulting remainder is 0, then p(x) is divisible by q(x) (i.e. there are no remainders).
Problem 1)
We are given:
[tex]p(x)=x^3+3x^2+3x+1\text{ and } q(x)=x+1[/tex]
We should find the remainder when dividing p(x) and q(x). We can use the Polynomial Remainder Theorem. When dividing a polynomial p(x) by a binomial in the form of (x - a), then the remainder will be p(a).
Here, our divisor is (x + 1) or (x - (-1)). So, a = -1.
Then by the Polynomial Remainder Theorem, the remainder when performing p(x)/q(x) is:
[tex]p(-1)=(-1)^3+3(-1)^2+3(-1)+1=0[/tex]
The remainder is 0, satisfying the Factor Theorem. p(x) is indeed divisible by q(x).
Problem 2)
We are given:
[tex]p(x)=x^3-2x^2+6x-27\text{ and } q(x)=x-3[/tex]
Again, use the PRT. In this case, a = 3. So:
[tex]p(3)=(3)^3-2(3)^2+6(3)-27=0[/tex]
It satisfies the Factor Theorem.
Problem 3)
We are given:
[tex]p(x)=x^n-10^n\text{ and } q(x)=x-10[/tex]
Use the PRT. In this case, a = 10. So:
[tex]p(10)=(10)^n-10^n=0[/tex]
It satisfies the Factor Theorem.
Since all three cases satisfy the Factor Theorem, p(x) is divisible by q(x) in all three instances.
In a geometric sequence, the 1st term is 8 and the 3rd term is 72. Given a positive common ratio, find the 7th term.
Answer:
see explanation
Step-by-step explanation:
The n th term of a geometric sequence is
= a
where a is the first term and r the common ratio
Both a and r have to be found
Given a₃ = - 2, then
ar² = - 2 → (1)
Given a₇ = - 32, then
a = - 32 → (2)
Divide (2) by (1)
= , that is
= 16 ( take the fourth root of both sides )
r = 2 ← common ratio
Substitute r = 2 into (1)
a × 2² = - 2, that is
4a = - 2 ( divide both sides by 4 )
a = - ← first term
Hence
= - ← explicit formula
and
= - × = - 0.5 × 512 = - 256

hola!!thanks for the fact 81,300 from scientific notation
The management of a department store has decided to enclose an 800 sq. ft.area outside the building for displaying potted plants and flowers. One side willbe formed by the exterior wall of the store, two sides will be constructed of pineboards, and the fourth side that is opposite to the wall will be made of galvanizedsteel fencing. If the pine board fencing costs $6/ft. and thesteel fencing costs $3/ft,determine the dimensions of the enclosure that can be erected at minimum cost
Answer:
Dimension of the enclosure is 56.56 ft * 14.14 ft
Step-by-step explanation:
Given -
Let us suppose that x is the length of steel fence and y is the length of one side of pine boards
We know that - xy = 800.
y = 800/x
Let us say that C is the cost of fence
= 3x + 6(2y) = 3x + 12y = 3x + 12(800/x)
C = 3x + 9600x-1, x > 0
C' = 3 - 9600x-2 = (3x2-9600)/x2
C' = 0 when 3x2 = 9600
x2 = 3200
x = √3200 ft ≈ 56.56 ft
So, the cost is minimized when x ≈ 56.56 ft and y = 800/x ≈ 14.14 ft
