A bag contains 12 red marbles the ratio of red marbles to blue marbles is 4:3 find the number of blue marbles in the bag

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: 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

If 5 mugs cost $28.20, we have equation:

Initial 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

Answer:

md(-2,-1)

Step-by-step explanation:

Md=(x1+x2/2,y1+y2/2)

or,Md=(-1-3/2,2-4/2)

or,Md=(-4/2,-2/2)

•°•Md=(-2,-1)

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]

Answer:

8, 6, 4, 2

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

Plug n =4

f(1)=-2(4-1)+8 = -2*3+8 = -6+ 8 = 2

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.

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

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.

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
