Answer:

0.357

Step-by-step explanation:

The computation of the probability of sale for the last book that the bookstore should purchase for sale to a student is shown below

Probability is

= 1 - ((Cs ) ÷ (Cs + co))

= 1 - (($225 - $105) ÷ ($117 + ($105 - $40)))

= 1 - 0.6428

= 0.357

Here Cs represent the notional loss in the case when the demand is underestimated

And Co represent the notional loss in the case when the demand is overestimated

Answer:

-15

Step-by-step explanation:

Any number times itself is a positive number. The square of any number will be the same as the square of that number times -1

the answer

Answer:

y = 2x - 259/115 [slope-intercept]

-230x + 115y = -259 [standard form]

Step-by-step explanation:

First make sure both of the intersecting lines are in standard form: Ax + By = C.

Then, multiply one of the equations by a certain quantity so one of the variables can be canceled out.

For example:

given 5x + y = 7, and 3y = 4x - 5.

You can rearrange the second equation since it is not currently in standard form.

So all we need to do is subtract both sides by 4x since that will leave the constant of C by itself.

3y = 4x - 5 → 3y - 4x = 4x - 5 - 4x →

3y - 4x = -5.

Now adding a negative number is the same as subtracting a positive number, this is because subtraction is the opposite of adding.

So 3y - 4x = -5 = 3y + (-4x) = -5 →

-4x + 3y = -5

Answer:

The family will travel at least 4 days.

Step-by-step explanation:

The inequality would look like this:

350d ≤ 1400

it's ≤ because the problem said that they had to travel AT LEAST a distance of 1400.

To solve the inequality, use inverse operations.

350d ÷ 350 ≤ 1400 ÷ 350

d ≤ 4

the family will travel at least 4 days.

I hope this helped and if it did I would appreciate it if you marked me Brainliest. Thank you and have a nice day!

Step-by-step explanation:

Answer:

Connor has 7 nickles and 1 penny.

Step-by-step explanation:

7 * 5 = 35

5 is the value of a nickel.

1 * 1 = 1

35 + 1 = 36

Therefore, Connor has 7 nickels and 1 penny.

Answer:

The original price was $821.25

Step-by-step explanation:

The price of an object is $878.74 including a tax of 7%.

We are required to find the original price.

If the tax is 7%, then the total price is 100+7=107% of the original price.

Thus, $878.74 is the 107% of the original price x, thus:

x = $878.74/107*100 = $821.25

The original price was $821.25

Explanation:

The domain is the set of allowed x inputs. The range is the set of possible y outputs.

The set {-2,-1,0,1,2} represents all the possible x inputs

Let's plug each of those into the equation y = 3x-6 to find the corresponding paired out puts.

Note: y = f(x), so f(x) = 3x-6 is the same as y = 3x-6.

---------------

If x = -2, then,

y = 3x-6

y = 3(-2)-6

y = -6-6

y = -12

We see that x = -2 and y = -12 pair up together.

The value -2 in the domain maps to -12 in the range.

----------------

If x = -1, then,

y = 3x-6

y = 3(-1)-6

y = -3-6

y = -9

The input x = -1 in the domain maps to the output y = -9 in the range

So far the range consists of {-12, -9} in either order.

The answer is between A and D

-----------------

If x = 0, then,

y = 3x-6

y = 3(0)-6

y = 0-6

y = -6

So -6 is also part of the range. We have {-12, -9, -6} so far. The answer is still between A and D.

------------------

If x = 1, then,

y = 3x-6

y = 3(1)-6

y = 3-6

y = -3

The range updates to {-12, -9, -6, -3}

A and D are still equally valid

-------------------

We have one more x value to try

If x = 2, then,

y = 3x-6

y = 3(2)-6

y = 6-6

y = 0

Since y = 0 is in the range, instead of y = 1, this rules out choice A

The answer is therefore D.  {-12, -9, -6, -3, 0}

Answer:

J. 2(×-3)=22...........

Answer:

J. 2( x - 3 ) = 22

Step-by-step explanation:

All you need to do, is substitute the x with 14

2 ( x - 3 ) = 22

2 ( 14 - 3 ) = 22

use PEMDAS

2 * 14 - 2* 3 = 22

28 - 6 = 22

22 = 22

So this problem is the correct one

Hope this helped!

Step-by-step explanation:

We know that the slope-intercept form of the line equation

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

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

                                       ANALYZING TABLE 1

Part A)

Given table 1

x           0            1              2            3

y           1             3              5            7

From table 1, the y-intercept can be determined by setting  x=0 and checking the corresponding y-value.

so at x = 0, y = 1

Thus, the y-intercept is (0, 1).

From the graph, it is clear that the line W has a y-intercept (0, 1).

Therefore, table 1 represents the line W.

Part B)

Taking two points (0, 1) and (1, 3) to find the slope using the formula

m = (y₂-y₁) / (x₂-x₁)

m = 3-1 / 1-0 = 2/1 = 2

now substituting m = 2, and b = 1 in the slope-intercept form

y = mx+b

y = 2x+1

Thus, table 1 represents the line W with the equation line y = 2x+1

                                  ANALYZING TABLE 2

Part A)

Given table 2

x           0            1              2            3

y           0             3             6            9

From table 2, the y-intercept can be determined by setting  x=0 and checking the corresponding y-value.

so at x = 0, y = 0

Thus, the y-intercept (0, 0).

From the graph, it is clear that line F has a y-intercept (0, 0).

Therefore, table 2 represents the line F.

Part B)

Taking two points (0, 0) and (1, 3) to find the slope using the formula

m = (y₂-y₁) / (x₂-x₁)

m = 3-0 / 1-0 = 3/1 = 3

now substituting m = 3, and b = 0 in the slope-intercept form

y = mx+b

y = 3x+0

y = 3x

Thus, table 2 represents the line F with the equation y = 3x

                                    ANALYZING TABLE 3

Part A)

Given table 1

x           0            1              2            3

y           2             3             4            5

From table 3, the y-intercept can be determined by setting  x=0 and checking the corresponding y-value.

so at x = 0, y = 0

Thus, the y-intercept (0, 2).

From the graph, it is clear that line N has a y-intercept (0, 2).

Therefore, table 3 represents line N.

Part B)

Taking two points (0, 2) and (1, 3) to find the slope using the formula

m = (y₂-y₁) / (x₂-x₁)

m = 3-2 / 1-0 = 1/1 = 1

now substituting m = 1, and b = 2 in the slope-intercept form

y = mx+b

y = (1)x+2

y = x+2

Thus, table 2 represents the line N with the equation y = x+2

We already know the triangles are congruent because all of the sides of one triangle correspond directly with another. Then, this is a problem of correct labling. GTA goes from point G (top) to T (bottom) to A (left). If we rotate the triangle MEQ, it is laid out in the same way: point Q (top) to point M (bottom) to point E (left or right).

Answer:

29 1/2-7 3/4 is 21.75

Then 21.75-1/2 is 21.25

Step-by-step explanation:

There is [tex]15\frac{1}{4}[/tex]c of gumbo soup left after Kingston's family ate and he shared some with his neighbor.

A fraction is written in the form of p/q, where q ≠ 0.

Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.

Given, Kingston made a pot of [tex]29\frac{1}{2}[/tex] of gumbo soup.

His family ate some of the gumbo for lunch. this changed the amount of the pot by [tex]-7\frac{3}{4}[/tex].

So, Reaming gumbo soup is ([tex]29\frac{1}{2} - 7\frac{3}{4}[/tex]).

= (59/2 - 31/4).

= (118 - 31)/4.

= 87/4c of gumbo soup.

Then he gave some gumbo to his neighbors. This changed the amount in the pot by -6 1/2c.

= (87/4 - 13/2)c.

= (87 - 26)/4c.

= 61/4.

= [tex]15\frac{1}{4}[/tex]c of gumbo soup.

Answer:

0.2

Step-by-step explanation:

Given the regression model :

y = 1.6x - 4.1

At x = 3

Predicted value = 1.6(3) - 4.1 = 0.7

If actual value at x = 3 is 0.9

The residual value at x = 3 ;

Residual value is the difference between the actual and predicted value :

Actual at x = 3 minus predicted at x = 3

Hence, Residual = 0.9 - 0.7 = 0.2

Residual is the difference between the predicted value and the actual value of the response variable

The residual at x = 3 is 0.2

The linear regression is given as:

[tex]y = 1.6x - 4.1[/tex]

The predicted value at x = 3 is calculated by substituting 3 for x in the linear regression

So, we have:

[tex]y = 1.6 \times 3 - 4.1[/tex]

[tex]y = 4.8 - 4.1[/tex]

[tex]y = 0.7[/tex]

The actual value is given as 0.9.

So, the residual is calculated using:

[tex]Residual =Actual - Predicted[/tex]

This gives

[tex]Residual =0.9 - 0.7[/tex]

[tex]Residual =0.2[/tex]

Hence, the residual at x = 3 is 0.2
