Students were selected at random in a local high school to see if there was an association between gender and
participation in extracurricular activities. What percent of females participate in extracurricular activities?
(1) 25%
(3) 44%
(2) 53%
(4) 72%
Extracurricular
No Extracurricular
Total
Gender
Male Female Total
24
19 43
16 17 33
40 36 76
===========================================================
Explanation:
The question asks "What percent of females participate in extracurricular activities?" This means we only focus on the second column. There are 36 women, and of this total, 19 are in extracurricular activities.
Dividing the two values leads to approximately 19/36 = 0.52777 which rounds to 0.53
Then we move the decimal to the right two spots to get 53%
Roughly 53% of the female students participate in extracurricular activities.

On a certain hot summer's day, 232 people used the public swimming pool. The daily prices are $1.50 for children and $2.25 for adults. The receipts for admission totaled $435.75. How many children and how many adults swam at the public pool that day?
Answer:
children is 115 and adult is 117
Step-by-step explanation:
Given
let the number of children be x
and the number of adults be y
so
x+y=232----------------1
We are told that the daily prices are $1.50 for children and $2.25 for adults
so
1.5x+2.25y= 435.75-------------------2
Hence the system of equation for the situation is
x+y=232-----1
1.5x+2.25y= 435.75-------2
From 1 x=232-y
Put this in Eqn 2
1.5(232-y)+2.25y= 435.75
348-1.5y+2.25y= 435.75
collect like terms
-1.5y+2.25y= 435.75-348
0.75y=87.75
divide both sides by 0.75
y= 87.75/0.75
y=117
the number of adults is 117
put y= 117 in eqn 1
x+117=232
x=232-117
x=115
The number of children is 115

The polygons are similar. The area of one polygon is given. Find the area of the other polygon.
4 cm
12 cm
A = 10 cm
Area =
cm2
Answer:
90 cm²
Step-by-step explanation:
Given that both triangles are similar, it follows that the ratio of their area equals the square of their corresponding sides.
Let the area of the other triangle be x. Therefore:
[tex] \frac{10}{x} = \frac{4^2}{12^2} [/tex]
[tex] \frac{10}{x} = \frac{16}{144} [/tex]
Cross multiply
[tex] 10*144 = 16*x [/tex]
[tex] 1440 = 16x [/tex]
Divide both sides by 16
90 = x
Area of the other polygon = 90 cm²
Answer:
Answer is 90

Mr. Johnson bought flowers to plant in flats in his yard. Each flat has 6 yellow flowers and 8 red flowers. Simplify the expression 6f+8f
Answer:
the simplified expression is 14f.
Step-by-step explanation:
Given expression;
6f + 8f
This expression is simplified by adding the two terms together since they are like terms.
6f + 8f = 14f
Therefore, the simplified expression is 14f.
y = 4x+1
3x + 2y = 13
Please and quickly
Answer:
x=1 and y = 5
Step-by-step explanation:
you add y = 4x+1 into the equation
3x+2(4x+1)=13
3x + 8x + 2 = 13
11x = 11
x = 1
then you just add the x into the equation y = 4x+1
4(1)+1
y = 5
1 - 2x = -x -3

deb and luke go to the pi-rate entertainment store to purchase cds (c) and dvds (d). deb buys 3 dvds and 2 cds for $63 (before sales tax) at the same item prices, luke pays $46 for 1 dvd and 4 cds (before sales tax). write and solve a system of equations to determine the cost of 1 cd and dvd
We are given here the individual costs of DVD and CD as well as the total sales and the number of items sold on one day. To solve the number of DVDs and CDs sold each, we devise two independent linear equations:
(1) x + y = 39
(2) 4x + 7y = 204
x- number of DVDs; y - number of CDs
solving, x= 23 DVDs

Which of the following best describes the graph above?
A.
neither a relation nor a function
B.
function only
C.
relation only
D.
both a relation and a function
Answer:
Option C
Step-by-step explanation:
To test a graph whether it represents a function or relation we conduct a vertical line graph.
If the vertical line intersect the graph at two different points, graph represents a relation only.
By analyzing the given graph with the vertical line test,
Since, a vertical line (x = -4) intersect the graph at two points (y = -1 and y = 5),
Given graph represents a relation only.
Option C is the answer.

Factor the following polynomial completely
x^2-3x-10
I hope it will helps u
Step-by-step explanation:As given
x²-3x-10
Now according to the one of the rule of factorization ,
we have to find such two values whose product becomes equal to the
"product of first and last term " and if we sum those numbers it should be equal to the "middle term of it".
so such numbers are -5x and +2x
if we add or multiply them we get the above
as adding -5x+2x=-3x (middle term)
also multiplying -5x*2x=-10x² (product of 1st and last term)
so now , we can write as,
x²-3x-10
=x²-5x+2x-10
now making groups of 2 terms,
=(x²-5x)+(2x-10)
now common
=x(x-5)+2(x-5)
now common(x-5)
=(x-5)(x+2) This is the required factors.....
Identify the value of a if
y= a (x - 2) (2x + 4)
and the point (4,8) is on the graph.
Pls help fast
Answer:
a=1/3
Step-by-step explanation:
from the point on the graph
x=4 and y=8
substitute them into the equation:
y=a(x-2) (2x+4)
you will get
8=a(4-2) (2(4)+4)
8=a(2) (8+4)
8=a(2) (12)
8=2a×12
8=24a
divide both sides by 24
8/24=24a/24
1/3=a or a=1/3

Jill is studying a strange bacterium. When she first looks at the bacteria, there are initially.
100 cells in her sample. The next day, there are 300 cells (Day 1). Intrigued, she comes
back the next day to find that there are 900 cells (Day 2)!
bo.
How many bateria cells will there be when Jill looks at her sample on Day 4?
Answer:
8100
Step-by-step explanation:
We first see that in the first day it tripled from 100 to 300 this is the pattern that is seen throughout this whole experemint, we can see that the cells triple again on the second day to get 900 cells from this. It is likely to say that they will triple again on the third day to get 2100 and again on the fourth to get 8100

What are 2 ways i could solve 7-(4p+3)=-3(p+2)-(2p+3)
Answer:
Simplifying
7 + -1(4p + 3) = -3(p + 2) + -1(2P + 3)
Reorder the terms:
7 + -1(3 + 4p) = -3(p + 2) + -1(2P + 3)
7 + (3 * -1 + 4p * -1) = -3(p + 2) + -1(2P + 3)
7 + (-3 + -4p) = -3(p + 2) + -1(2P + 3)
Combine like terms: 7 + -3 = 4
4 + -4p = -3(p + 2) + -1(2P + 3)
Reorder the terms:
4 + -4p = -3(2 + p) + -1(2P + 3)
4 + -4p = (2 * -3 + p * -3) + -1(2P + 3)
4 + -4p = (-6 + -3p) + -1(2P + 3)
Reorder the terms:
4 + -4p = -6 + -3p + -1(3 + 2P)
4 + -4p = -6 + -3p + (3 * -1 + 2P * -1)
4 + -4p = -6 + -3p + (-3 + -2P)
Reorder the terms:
4 + -4p = -6 + -3 + -2P + -3p
Combine like terms: -6 + -3 = -9
4 + -4p = -9 + -2P + -3p
Solving
4 + -4p = -9 + -2P + -3p
Solving for variable 'p'.
Move all terms containing p to the left, all other terms to the right.
Add '3p' to each side of the equation.
4 + -4p + 3p = -9 + -2P + -3p + 3p
Combine like terms: -4p + 3p = -1p
4 + -1p = -9 + -2P + -3p + 3p
Combine like terms: -3p + 3p = 0
4 + -1p = -9 + -2P + 0
4 + -1p = -9 + -2P
Add '-4' to each side of the equation.
4 + -4 + -1p = -9 + -4 + -2P
Combine like terms: 4 + -4 = 0
0 + -1p = -9 + -4 + -2P
-1p = -9 + -4 + -2P
Combine like terms: -9 + -4 = -13
-1p = -13 + -2P
Divide each side by '-1'.
p = 13 + 2P
Simplifying
p = 13 + 2P

(x2 + 5x + 4)/(x + 2)
do a division of this polynomial and you get; (x + 3) - 2/(x+2), you could leave the answer like this or you could simplify by using the LCM method
= [(x+2)(x+3) - 2]/(x + 2)
checking; (x + 2)*[(x+2)(x+3) - 2]/(x + 2) = (x+2)(x+3) - 2 = x2 +5x + 6 - 2 = x2 +5x + 4 (proven)

p + 2q = 11
2p + q = 10
Answer:
p = 3
q = 4
Step-by-step explanation:
p + 2q = 11 --------------------(I)
p = 11 - 2q
2p + q = 10 --------------------(II)
Substitute p = 11 -2q in equation (II)
2(11 - 2q) + q =10
2*11 - 2q *2 + q = 10
22 - 4q + q = 10
22 - 3q = 10
-3q = 10 - 22
-3q = -12
q = -12/-3
q = 4
Plugin q = 4 in equation (I)
p + 2q = 11
p + 2*4 = 11
p + 8 = 11
p = 11 - 8
p = 3
