Answer:
9
Step-by-step explanation:
this can be written as an equation.
12/x=4/3
and it is just easy now, you see what you multiply 4 by to get 12 and it is 3, so that means you have to multiply 3 by 3
3 times 3 is 9, so the answer is 9
Answer:
Hello There!!
Step-by-step explanation:
First look at the ratios the red marbles ratio is 4 and the blue marbles ratio is 3.
You already know that there are 12 ratios in the bag so 12÷4=3(1 ratio equals 3 marbles)
Therefore,3×3=9.So the answer is 9 blue marbles.
hope this helps,have a great day!!

Adams High School is going to select a committee. The committee will have a faculty member, a male student, a female student, a parent, and a school board member. Here are the positions and the people interested in each. Position People interested Faculty member Mr. Jackson, Mrs. Washington Male student Tom, Omar, Keith, Justin Female student Donna, Charmaine, Rita, Keiko Parent Dr. Ward, Ms. Allen, Mrs. Flores, Mrs. Smith School board member Dr. Davis, Ms. Young, Mrs. King, Mr. Adams Based on this list, how many ways are there to fill the five committee positions?
Answer:
512 ways
Step-by-step explanation:
Given
Selection
Faculty Member = 1
Male Student = 1
Female Student = 1
Parent = 1
School Board Member = 1
Select from:
Faculty Member = 2
Male Student = 4
Female Student = 4
Parent = 4
School Board Member = 4
Required
Determine how many ways they can be selected
There are 2 faculty members of which 1 will be selected from.
Any of these two members may be selected.
So, Selection = 2
There are 4 male students of which 1 will be selected from.
Any of these four students may be selected.
So, Selection = 4
There are 4 female students of which 1 will be selected from.
Any of these four students may be selected.
So, Selection = 4
There are 4 parents of which 1 will be selected from.
Any of these four parents may be selected.
So, Selection = 4
There are 4 school board members of which 1 will be selected from.
Any of these four members may be selected.
So, Selection = 4
Total number of selection is then calculated as thus:
[tex]Selection = 2 * 4 * 4 * 4 * 4[/tex]
[tex]Selection = 512[/tex]
Hence, there are 512 ways

Answer:
a. 2/5
b. 1/2
c. 100/9
Step-by-step explanation:
a: Multiply bottom and top by 100 to keep values the same and make the fraction a whole fraction:
.12 × 100 = 12
.3 × 100 = 30
Simplify: 12/30 = 2/5
b: Multiply bottom and top by 1,000 to keep values the same and make the fraction a whole fraction:
.125 × 1,000 = 125
.25 × 1,000 = 250
Simplify: 125/250 = 1/2
c: Multiply bottom and top by 100 to keep values the same and make the fraction a whole fraction:
4 × 100 = 400
.36 × 100 = 36
Simplify: 400/36 = 100/9

The graph of y = |x − 3| + 2 is reflected across the x-axis and then translated down 2 units. What is an equation of the transformed graph?
Answer:
y=-|x − 3|
Work
y = |x − 3| + 2
-2 -2
y = |x − 3|
add a neg before the absolute value
y=-|x − 3|
Transformation involves changing the position of a graph
The equation of the transformed graph is [tex]\mathbf{y = -|x -3| - 4}[/tex]
The equation is given as:
[tex]\mathbf{y = |x -3| + 2}[/tex]
The rule of reflection across the x-axis is:
[tex]\mathbf{(x,y) \to (x,-y)}[/tex]
So, we have:
[tex]\mathbf{y = -|x -3| - 2}[/tex]
The rule of translation 2 units down is:
[tex]\mathbf{(x,y) \to (x,y-2)}[/tex]
So, we have:
[tex]\mathbf{y = -|x -3| - 2 - 2}[/tex]
[tex]\mathbf{y = -|x -3| - 4}[/tex]
Hence, the equation of the transformed graph is [tex]\mathbf{y = -|x -3| - 4}[/tex]

Step-by-step explanation:
f(n)=-2(n-1)+8
Plug n =1
f(1)=-2(1-1)+8 = - 2*0+8 = 0+ 8 = 8
Plug n =2
f(1)=-2(2-1)+8 = - 2*1+8 = - 2+ 8 = 6
Plug n =3
f(1)=-2(3-1)+8 = -2*2+8 = -4+ 8 = 4

A store sells mugs. Each mug costs the same amount. During a sale, the store reduces the price of each mug by $1.75. Wen spends $28.20 on 5 mugs at the sale price. What was the price of 1 mug before the sale?
Answer:
$7.39Step-by-step explanation:
Let the initial price be x
Then the reduced price is
x - 1.75If 5 mugs cost $28.20, we have equation:
(x - 1.75)*5 = 28.20x - 1.75 = 28.20/5x - 1.75 = 5.64x = 1.75 + 5.64x = 7.39Initial price for 1 mug was $7.39
Answer:
so the price for 1 mug was $7.39
Step-by-step explanation:
initial price will be P
Then the lower price is
x - 1.75
If 5 mugs cost $28.20 then we have to write an equation in order to find the price for 1 mug.
(P - 1.75)*5 = 28.20
P - 1.75 = 28.20/5
P - 1.75 = 5.64
P = 1.75 + 5.64
P = 7.39
Initial price for 1 mug was $7.39

Given :
Skies travel charges two-fifty for a plane ticket and $28 per day for rental car.
For the same trip, r&r travels charges 305 for a plane ticket and 23 per day for car rental.
To Find :
The minimum number of days in martin's vacation should be or r&r travel to be a better deal for him.
Solution :
Let, minimum number of days are x.
So, cost charged by Skies travel is, [tex]c_1 = 25+28x[/tex]
Cost charged by r&r travels is, [tex]c_2 = 305 + 23x[/tex]
r&r should be better deal when :
[tex]c_2 < c_1\\\\305 + 23x <25 + 28x\\\\5x >280\\\\x>56[/tex]
So, for better deal at r&r minimum number of vacation days is 57.
Hence, this is the required solution.

The bicycle with a 30-inches diameter rolls approximately 28.8 more than a tire with the diameter with 21-inches.
How to solve:
First use the formula: C = 3.14dReplace the d value with 30 and solve the equation:C = 3.14 x 30 ⇒ 94.2477796077
Then solve the equation again but 21 as the d value:C = 3.14 x 21 ⇒ 65.9734457254
Then subtract 65.9734457254 from 94.2477796077 to get the approx. answer of 28.8Evaluate the function: f (x)=4x-1. Find f (5)
Answer:
f(5)= 4(5)-1
=20-1
=21
The evaluated value of f(5) is 19, which is determined by performing the arithmetic operations.
The linear function is given as follows:
f(x) = 4x - 1
To evaluate the function f(x) = 4x - 1 and find f(5), we substitute x = 5 into the function.
f(5) = 4(5) - 1
= 20 - 1
= 19
Therefore, f(5) is equal to 19.
The function f(x) = 4x - 1 represents a linear equation. In this case, when x is equal to 5, the value of f(x) can be calculated by substituting x = 5 into the equation.
By performing the necessary arithmetic operations, we find that f(5) is 19.

A medical school claims that more than 28% of its students plan to go into general practice. It is found that among a random sample of 130 of the schools students 32% of them plan to go into general practice. Find the p- value for a test of the schools claim
Answer: 0.1548
Step-by-step explanation:
The P value can be calculated from the value of the test statistic :
H0 : p ≤ 0.28
H1 : p > 0.28
Zstat :
(p - p0) / √((p0(1-p0))/n)
p = 0.32 ; p0 = 0.28 ; n = 130
(0.32 - 0.28) / √((0.28(1 - 0.28))/130)
Zstat = 1.0157490
Zstat = 1.016
Using a 0.05 significance ;
The P value obtained using the p value from z statistic calculator is 0.154815

What Is The Difference Between 1+1 And 1x1?
Answer:
1+1=2 and 1x1= 1
Step-by-step explanation:
If you add something you take the first number and add it to the second one. If it is multiplication, you take the first number, and multiply by itself, so it would be 1 times itself (1) and it is kind of like 1+0 which equals 1. It doesn't sound like a lot, but when you get into Algebra and Pre-Algebra, etc. it does come along easier.
Answer:
1+1=2 and 1x1= 1
