The mean of the histogram is 904.8

The mean of the histogram is calculated as

Mean = Sum of the product of carrying load and frequency/Sum of frequency

Using the above as a guide, we have the following:

Mean = (870 * 5 + 890 * 7 + 910 * 8 + 930 * 4 + 950 * 3)/(5 + 7 + 8 + 4 + 3)

Evaluate

Mean = 904.8

The inequality that represents the graph is option D: 13x - 3y - 14 < 0.

What is an inequality?

In Algebra, an inequality is a mathematical statement that uses the inequality symbol to illustrate the relationship between two expressions. An inequality symbol has non-equal expressions on both sides. It indicates that the phrase on the left should be bigger or smaller than the expression on the right, or vice versa.

The x-intercept is a = 1.077

The y-intercept is b = -4.677

The equation of line having x-intercept a and y-intercept b is -

x/a + y/b = 1

The equation of line having x-intercept 1.077 and y-intercept -4.677 is -

x/1.077 + y/-4.677 = 1

y/-4.677 = 1 - x/1.077

y = (1 - x/1.077)-4.677

y = -4.677 + 4.677x/1.077

y = -4.677 + 4.342x

Multiply both sides by 3 -

3y = 3(-4.677 + 4.342x)

3y = -14.031 + 13.026x

Now, the line 3y = -14.031 + 13.026x divide the xy-plane in two regions and the region given in the graph is satisfied by the origin.

Also, the line 3y = 14.031 + 13.026x is dotted and not dark ,therefore, the points on the line are not included in the shaded region.

Therefore, the inequality that represents the shaded region is -

0 > - 3y - 14.031 + 13.026x ≈ 13x - 3y - 14 < 0

Answer: $50

Step-by-step explanation:

Let's denote the amount of money Gabriella had before buying the cake as "a". Then we can write an equation to find "a":

a - $25.52 = $24.48

Adding $25.52 to both sides:

a = $25.52 + $24.48

So,

a = $50

Therefore, Gabriella had $50 before buying the cake.

The loss is given as difference of cost price and selling price and the selling price is R750.

Mathematicians use the profit and loss formula to calculate market prices for goods and to assess how lucrative a company is. There is a selling price and a cost price for every goods. We can determine the profit made or loss suffered for a certain product based on the values of these prices. Cost price, fixed, variable, and semi-variable costs, selling price, marked price, list price, margin, etc. are some of the key words that are addressed in this article.

Given that the cost price is R600, and the profit is R150.

The profit is given as:

P = SP - CP

150 = SP - 600

SP = 150 + 600

SP = 750

The loss is given as:

L = CP- SP

The two digit number is 35.

Writing a mathematical statement in the form of a mathematical equation for the correct analysis, measurement and solutions.

Given is that Elizabeth is thinking of a two - digit number. When the tens digit is subtracted from the ones digit, the difference is 2. One-fifth of the number is 1 less than the sun of the digits.

Let the number be (xy).

We can write the two digit number as -

xy = 10x + y                                                   ... Eq { 1 }

Now, it is given that when the tens digit is subtracted from the ones digit, the difference is 2. We can write -

y - x = 2                                                              ... Eq { 2 }

Also, one - fifth of the number is 1 less than the sun of the digits. We can write -

(1/5)(10x + y) = (x + y) - 1                                         ... Eq { 3 }

Now, from eq { 1 } and eq { 2 }, we have -

y - x = 2    

y = x + 2

and

(1/5)(10x + y) = (x + y) - 1    

(1/5)(10x + x + 2) = (x + x + 2) - 1

(1/5)(11x + 2) = 2x - 1

11x + 2 = 10x - 5

x = - 7

y = -5

So, the number would be -

xy = 35

Therefore, the two digit number is 35.

5. In parallelogram, adjacent angles is supplementary to each other; then:

∠A + ∠B = 180°

∠B = 129°

6. In parallelogram, adjacent angles is supplementary to each other; then:

∠M + ∠N = 180°

95 + ∠N = 180°

∠N = 85°

In the given parallelogram LMNQ, the length of MP is 8.2 and PN is 7. Angle ∠MQN is 29° and ∠MLQ is 100°.

7. LM can be calculated by focusing on triangle MLQ. Under the Sinus Law, we can find that:

LM / sin LQM = MQ / sin MLQ

MQ is one of the parallelogram diagonal. MP is the mid point, then MQ is twice of MP.

MQ = 2(8.2) = 16.4

∠MLQ = 100°

∠LQN = 180° - 100°

∠LQN = 80°

∠LQN = ∠LQM + ∠MQN

80° = ∠LQM + 29°

∠LQM = 51°

LM / sin 51 = 16.4 / sin 100

LM / 0.78 = 16.4 / 0.98

LM = 12.9 = 13

8. LQ is parallel with MN; then they share the same length.

LQ = MN

MN can be calculated by focusing on triangle QMN. Under the Sinus Law:

MN / sin MQN = MQ / sin MNQ

∠MNQ is the opposite angle of ∠LMQ, then ∠MNQ = ∠LMQ = 100

MN / sin 29 = 16.4 / sin 100

MN = 8.07

MQ = 2(8.2)

MQ = 16.4

12. ∠NQL = 80°

13. ∠MNQ = ∠MLQ = 100°

Lydia invested an amount of $1110 in the 12% savings account and $1960 in the 13% savings account.

Let's assume the amount invested in the 12% savings account "x". Then, the amount invested in the 13% savings account would be "x + 850".

The total interest earned is $388, so we can write the following two equations to represent the interest earned in each account:

0.12x + 0.13(x + 850) = 388

Expanding the second equation, we get:

0.12x + 0.13x + 110.5 = 388

Combining like terms and simplifying, we get:

0.25x = 277.5

Dividing both sides by 0.25, we get:

x = 1110

So, she invested $1106 in the 12% savings account and $1110 + 850 = $1960 in the 13% savings account.

The mean of the combined group can be calculated as follows:

   Calculate the total sum of test scores of both classes:

   Class 1: 36 students * 73.1 mean = 2631.6

   Class 2: 28 students * 67.4 mean = 1888.32

   Total: 2631.6 + 1888.32 = 4519.92

   Calculate the total number of students:

   Total students = 36 + 28 = 64

   Divide the total sum of test scores by the number of students to find the mean:

   Mean = 4519.92 / 64 = 70.9375.

Therefore, the mean of the combined group of 64 students is 70.9375.

An inverse variation function with a small value for k. Therefore, option C is  the correct answer.

Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is known as the "constant of proportionality".

The association between x and y can be classified in two ways, as follows:

Direct proportional: when the input x increases, the output y also increases.

Inverse proportional: when the input x increases, the output y decreases.

For this problem, we need an inverse proportional function, that has the following format:

y = k/x.

The lower the value of k, the lower the value of y when x goes to infinity.

Therefore, option C is  the correct answer.

Answer: First, calculate the total value of the shares after the price fall to $80:

value = 200 shares * $80/share = $16,000

Then, calculate the amount of money borrowed:

borrowed = $14,000 / (1 - margin requirement)

= $14,000 / (1 - 0.20)

= $14,000 / 0.80

= $17,500

Finally, calculate the percentage return on investment:

return = (value - borrowed) / borrowed * 100%

= ($16,000 - $17,500) / $17,500 * 100%

= -6.06%

The return on investment is -6.06%, meaning that the investment lost 6.06% of its value.

The slope of the linear relationship is equal to: A. negative five halves.

In Mathematics, the slope of a linear relationship can be determined by using this mathematical equation;

Slope (m) = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Based on the information provided, we can logically deduce the following slope and data points on the line:

Substituting the given data points into the slope formula, we have the following;

Slope, m = (y₂ - y₁)/(x₂ - x₁)

Slope, m = (-2 - 3)/(2 - 0)

Slope, m = -5/2
