The formula for the distributive property is expressed as, a × (b + c) = (a × b) + (a × c); where, a, b, and c are the operands. Here, the number outside the brackets is multiplied with each term inside the brackets and then the products are added.

Inequality that represents the coordinates that are not the solutions of this inequality is x < 7.5. The graph of the inequality is attached at the end.

The various operators used in inequalities for expression are -

Given is a inequality in one variable which is → x + 3.8 > 11.3.

PART - A

The inequality that represents the coordinates that are not the solutions of this inequality is -

x + 3.8 < 11.3

or

we can simplify it to get -

Subtract 3.8 from both sides -

x + 3.8 - 3.8 < 11.3 - 3.8

x < 7.5

PART - B

In order to plot the graph of this inequality, firstly we will plot the line of equation -

x = 7.5.

Since, the inequality is strict, make a dashed line to represent the equation.

Take the coordinates of origin O(0,0), and substitute it in the inequality -

0 < 7.5

which is true. Therefore, we will shade the complete side where origin lies.

The graph of the inequality is plotted an attached with the answer.

Therefore, inequality that represents the coordinates that are not the solutions of this inequality is x < 7.5. The graph of the inequality is attached at the end.

The slope of the line representing number of tests on the y-axis and the time in weeks on the x axis is 0.75.

As per the given question;

The total number of week is 36 weeks.

The total test conducted is 27.

As, number of tests are represented on the y-axis and the time in weeks on the x axis.

The slope is constant for the text and weeks.

Thus, slope (m) is determined  as;

m = Δy/Δx

m = number of tests/time in weeks

Put the values.

m = 27/36

m = 0.75

Therefore, the slope of the line representing number of tests on the y-axis and the time in weeks on the x axis is 0.75.

Using the normal distribution, it is found that:

a) 167 students in the class can be expected to receive a score over 60.

b) 11.07% of the class is expected to receive a score between 82 and 90.

The z-score of a measure X of a normally distributed variable with mean represented by [tex]\mu[/tex] and standard deviation represented by [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The mean and the standard deviation for the scores are given, respectively, by:

[tex]\mu = 72, \sigma = 9[/tex]

The proportion of students who scored over 60 is given by one subtracted by the p-value of Z when X = 60, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (60 - 72)/9

Z = -1.33.

Z = -1.33 has a p-value of 0.0918.

1 - 0.0918 = 0.9082.

Out of 184 students:

0.9082 x 184 = 167.

167 students in the class can be expected to receive a score over 60.

For item b, the proportion is the p-value of Z when X = 90 subtracted by the p-value of Z when X = 82, hence:

X = 90:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (90 - 72)/9

Z = 2.

Z = 2 has a p-value of 0.9772.

X = 82:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (82 - 72)/9

Z = 1.11

Z = 1.11 has a p-value of 0.8665.

0.9772 - 0.8665 = 0.1107.

Hence:

11.07% of the class is expected to receive a score between 82 and 90.

Answer:

$50400

Step-by-step explanation:

5/100*4000=200+4000=4200*12=50400

Answer:

$4,368

Step-by-step explanation:

At the beginning of the first year, the principal (amount deposited) is $4000 at 4% interest.

The rate of interest in decimal is r = 4%/100 = 0.04

Interest for 1 year = P x r = 4000 x 0.04 = $160

So at the end of the first year, Marty's 4000 deposit will have grown to $4,000 + $160 = $4, 160

He deposits this amount into a new account at 5% interest
Interest rate r = 5%/100 = 0.05
Interest = 4160 x 0.05 = $208.00

Total money at the end of the second year = 4160 + 208 = $4,368

The amount that Yolanda can expect to have in her account at the end of 2 years is $8,068.28.

The amount of money that Yolanda deposits twice in a year represents an annuity. An annuity is a series of payment that is made over a specified period of time. An ordinary annuity is when payment is made at the end of each period and not at the beginning of the period. Yolanda's deposit is an ordinary annuity.

When the amount deposited in an account earns interest that is compounded semi-annually, it means that both the amount that is invested and the interest that is already accrued increases in value two time in a year, every six month.

The formula that can be used to determine the future value of the amount that was deposited in the account is:

Future value = amount deposited x annuity factor

Annuity factor = {[(1+r)^n] - 1} / r

Where:

1,900 x[ {(1.04^4) - 1} / 0.04] = $8,068.28

The solution using the elimination method for the values of x, y and z are -1, 3 and 4 respectively.

To solve multiple equation in three variables using the elimination approach, we can either add or subtract the equations. To eliminate a variable, we add the equations when the coefficients of one variable are in opposition, and subtract the equations when the coefficients of one variable are equal.

Let us classify the given equations as:

3x + 4y - 5z = -11   →→→→ (A)

4х + у- z  = -5      →→→→→(B)

x- 3y + 3z = 2      →→→→→(C)

Multiplying equation(C) by 3 and equation (A) by 1 and subtracting we get:

3x + 4y - 5z = -11

3x  - 9y + 9z=    6

13y-14z=-17→→→→→→(D)

Multiplying equation(C) by 4 and equation (B) by 1 and subtracting we get:

4x-12y+12z = 8

4x + y - z    = -5

-13y+13z=13

or, z-y=1→→→→→→→(E)

Multiplying equation(E) by 13 and equation (D) by 1 and adding we get:

-13y+13z=13

13y-14z  =-17

-z=-4

or, z = 4

Substituting the value of z in the equation (E) we get:

z-y=1

or,  4-y = 1

or, -y = -3

or,  y = 3

Substituting the value of z and y in the equation (A) we get:

3x+4y-5z=-11

or, 3x+12-20=-11

or, 3x=-11+8

or, x=-1

Hence the solution of x, y and z are -1, 3 and 4 respectively .

B rents for $1.62 per sq. feet is much cheap and better as compared to A

Yard and feet are used to estimate the length. Both of the units are used in the royal and US customary system of measurements. The value of one yard is equal to three feet.

To compute Square yard to Square Feet, where Square yard is equal to 9 Square Feet, multiply the value in Square yard by 9. one can also use the Square yard to Square Feet calculator.

1 yard² = 9 feet²

A rents for $27 per yard squared

hence A rents $27 for 9 feet squared

hence A rents $3 per feet squared( $27/9) which is costlier than $1.62 per feet squared

Hence B is better as it is cost effective.

Just one or more of their routes have been changed. No changes to the shape are made because it is simply being moved from one location to another.

By utilizing the aforementioned guidelines, we can move the provided graph to the left, right, up, or down and graph the translated graphs.

The perimeter of tr8angle DEF that is similar to triangle ABC is: 18 cm.

If two triangles are similar to each other, and the perimeter of one is A with a side length of a, and the perimeter of the other is B with a side length of b, then, the following below is the ratio of their perimeters.

Perimeter of A/perimeter of B = a/b

Given that triangles ABC and DEF are similar triangles, we have the following:

Perimeter of triangle ABC = x

One side length of triangle ABC = 4 cm

Perimeter of triangle DEF = 12 + 6 + 9 = 27 cm

One side length of triangle DEF = 6 cm

Therefore:

x/27 = 4/6

Cross multiply

6x = (27)(4)

6x = 108
