Step-by-step explanation:

Hi there!

I don’t know how to properly answer step 1, but it looks like you already have the formula written down.

For step 2, divide 120 by 3 to find how many backpacks made in one hour, or 40 backpacks per hour.

600 backpacks = 40 backpacks/1 hour * t

Step 3: This may look complicated, but i promise it is not. All we have to do here is divide 600 by 40, or 15.

t = 15, or it will take 15 hours to make 600 backpacks.

I hope this helps!

Answer:

For first question, there is 12 marbles at first. So the probability of choosing blue marble is 3/12=1/4. Then marbles are not replaced, the total number is 11. The probability of choosing red is 5/11. So the finally answer is (1/4)*(5/11)=5/44. The same method for second question. Need to notice that you have already choose 1 white marble, so the number of white marble also changed. The answer is (4/12)*(3/11)=1/11.

Step-by-step explanation:

The probability of selecting 2 blue marbles without replacement will be 1/66.

Its simple notion is that something will most likely occur. The favorable event's proportion to the overall number of occurrences.

There are 4 white marbles, 6 red marbles, and 2 blue marbles.

Once a marble is selected, it is not replaced.

Then the total number of the marbles will be

Total marbles = 4 + 6 + 2

Total marbles = 12

Then the probability of selecting 2 blue marbles without replacement will be

P = 2/12 x 1/11

P = 2/132

P = 1/66

Answer:

So for the geometric mean, you would multiply the two numbers and put them under a radical

Step-by-step explanation:

3 times 10= 30

=[tex]\sqrt{30}[/tex]

The solution is : the geometric mean between 3 and 10 is √30.

The Geometric Mean (GM) in mathematics is the average value or mean that, by calculating the product of the values of the set of numbers, denotes the central tendency of the numbers. In essence, we multiply the numbers together and calculate their nth root, where n is the total number of data values.

here, we have,

Given:  two numbers 3 and 10

we have,

To Find: Geometric number of numbers in 3 and 10

Solution:

Let first number be a

Let second number be b

Geometric mean of two numbers a and b is √ab

Now,

First number is 3

Second number is 10

Geometric mean of both numbers is :

√3×10

=√30

Geometric mean is √30.

Hence, The solution is : the geometric mean between 3 and 10 is √30.

Step-by-step explanation:

-2z - 3 < 5 inequality is solved to z>-4.

Relationship between two expressions or values that are not equal to each other is called 'inequality.

The given inequality is -2z - 3 < 5

Minus two times of z minus three less than five.

-2z - 3 < 5

We need to solve this inequality, which means we need to solve of variable z.

Add 3 on both sides of inequality

-2z<8

Divide both sides by 2

-z<4

Multiply the given inequality by minus

z>-4

Hence, -2z - 3 < 5 inequality is solved to z>-4.

Step-by-step explanation:

y = 12(x)+28

(-1,16)

y = 12(-1)+28 = 16

(5,88)

y = 12(5)+28 = 88

Answer:

We conclude that the function [tex]f(x) = 12x + 28[/tex]  works.

The graph of the function y = 12x + 28 is also attached below.

Step-by-step explanation:

Given that the line passes through the points

Let us determine the slope between (-1, 16) and (5, 88) using the slope formula

[tex]\mathrm{m}=\frac{y_2-y_1}{x_2-x_1}[/tex]

where m is the slope between (x₁, y₁) and (x₂, y₂)

In our case:

so subtituting (x₁, y₁) = (-1, 16) and (x₂, y₂) = (5, 88) in the slope formula

[tex]\mathrm{m}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{88-16}{5-\left(-1\right)}[/tex]

Refine

[tex]m=12[/tex]

Thus, the slope of the line is: m =  12

Important Tip:

The slope-intercept form of the line equation is

[tex]y = mx + b[/tex]

where m is the slope and b is the y-intercept

now substituting m = 12 and the point (-1, 16) in the slope-intercept form of the line equation

[tex]y = mx + b[/tex]

[tex]16 = 12(-1) + b[/tex]

switch the equation

[tex]12(-1) + b = 16[/tex]

[tex]-12 + b = 16[/tex]

Add 12 to both sides

[tex]-12+b+12=16+12[/tex]

Simplify

[tex]b=28[/tex]

Thus, the y-intercept of the line is: b = 28

now substituting m = 12 and b = 28 in the slope-intercept form of the line equation

[tex]y = mx + b[/tex]

[tex]y = 12x + 28[/tex]

Thus the equation of the line is:

[tex]y = 12x + 28[/tex]

or

[tex]f(x) = 12x + 28[/tex]        ∵ [tex]y = f(x)[/tex]

Hence, we conclude that the function [tex]f(x) = 12x + 28[/tex]  works.

The graph of the function y = 12x + 28 is also attached below.

Answer:

1 piece of equal length = 2 3/4 yards of cloth

Step-by-step explanation:

Sariyah cuts 22 yards of cloth into 8 pieces of equal length the lengths of each pieces falls between two measures

8 pieces of equal length = 22 yards of cloth

1 piece of equal length = x yards

Cross Multiply

8 pieces × x yards = 22 yards × 1 piece

x yards = 22 yards/8

x yards = 11/4

x yards = 2 3/4 yards

Therefore, 1 piece of equal length = 2 3/4 yards of cloth

The points are pointing up in a positive direction so it would be postive.

Answer: Two lines that intersect at about three halves comma negative 3. One line has a positive slope and the other has a negative slope.

Step-by-step explanation:

Given equations of line:

y = 2x – 6               ...(i)

y = –4x + 3            ...(ii)

On comparing with y=mx+c (slope-intercept form), where m= slope ,= y-intercept.

(i) has positive slope (2) and (ii) has negative slope(-4).

Eliminate (ii) from (i), we get

0 = 6x-9

⇒ 6x=9

⇒ [tex]x=\dfrac32[/tex]

Put value of x in (i), we get

[tex]y=2(\dfrac32)-6\\\\\Rightarrow\ y=3-6=-3[/tex]

Explanation:

The fraction 6/(-7) is the same as -6/7

We have the two fraction -6/7 and 3/11 being divided

The denominators are 7 and 11 respectively.

The LCM of those two numbers is 77 since 7*11 = 77

If we multiply each of those fractions (-6/7 and 3/11) by 77, then we'll clear out those inner denominators to simplify this complex fraction into a nicer one.

77*(-6/7) = -66

77*(3/11) = 21

This means the original complex fraction becomes -66/21

We can further simplify this by dividing each part by the GCF 3

-66/3 = -22

21/3 = 7

Therefore, the final answer is -22/7
