You bought 3/4 pound of fudge for 6.75. Write and solve an equation to find the cost of the fudge per pound.

Answers

Given:

You bought [tex]\dfrac{3}{4}[/tex] pound of fudge for 6.75.

To find:

The equation and solve the equation to find the cost of the fudge per pound.

Solution:

Let x be the cost of the fudge per pound.

You bought [tex]\dfrac{3}{4}[/tex] pound of fudge for 6.75.

[tex]\dfrac{3}{4}x=6.75[/tex]

[tex]3x=6.75\times 4[/tex]

[tex]3x=27[/tex]

Divide both sides by 3.

[tex]x=\dfrac{27}{3}[/tex]

[tex]x=9[/tex]

Therefore, the required equation is [tex]\dfrac{3}{4}x=6.75[/tex] and the cost of the fudge is 9 per pound.

Find the standard deviation of the data set below. Round to the nearest tenth,
6, 5, 2, 5,8

Answers

Answer:

The standard deviation = 1.9

Step-by-step explanation:

standard deviation, ρ = sqrt ( [tex]\frac{sum(x_{i} - u)^{2} }{N}[/tex])

Where u is the mean of the data, [tex]x_{i}[/tex] each given value, and N is the number of data given.

Mean, u = [tex]\frac{6+5+2+5+8}{5}[/tex]

              = 5.2

So that;

[tex](6-5.2)^{2}[/tex]  = [tex](0.8)^{2}[/tex] = 0.64

[tex](5-5.2)^{2}[/tex] = [tex](-0.2)^{2}[/tex] = 0.04

[tex](2-5.2)^{2}[/tex]  = [tex](-3.2)^{2}[/tex] = 10.24

[tex](5-5.2)^{2}[/tex] = [tex](-0.2)^{2}[/tex] = 0.04

[tex](8-5.2)^{2}[/tex] = [tex](2.8)^{2}[/tex] = 7.84

Sum = 18.8

So that;

[tex]\sqrt{\frac{18.8}{5} }[/tex]  = [tex]\sqrt{3.76}[/tex]

          = 1.9391

          = 1.9

The standard deviation of the given data is 1.9

Answer:

Step-by-step explanation:

In this case, we can assume that this function follows a linear function. In this case, the general expression would be:

y = a + bx

Where:

a: Y intercept

b: slope of the function

To get the slope we need to apply the following expression:

b = y₂ - y₁ / x₂ - x₁

We already have two points, (80,0) and (40,16) from here, we can determine the slope:

b = 16 - 0 / 40 - 80

b = -16/40

b = -2/5

Now that we know the slope, we can determine the y-intercept if it have:

a = y - bx

Using any point, we can calculate it:

a = 0 - (-2/5*80)

a = 0 + 160/5

a = 32

With these two values, we can write the function:

h(x) = 32 - 2/5x

Write a percent proportion for the bar diagram
shown.

Answers

Answer:

If 68% is 17 then 100 percent is 25 I think

Step-by-step explanation:

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

68% = 17

100% = 25

The percent proportion for the bar diagrams are:

17and 25.

What is a percentage?

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

There are two bar diagrams.

Blue bar diagram:

68% = 17

Red bar diagram:

68% = 17

Multiply both sides by 100/68.

100% = 100/68 x 17

100% = 25

Thus,

68% = 17

100% = 25

The percent proportion for the bar diagrams are:

17and 25.

At an apple orchard, customers use a standard-size box when picking apples. The table shows the total weight of the box of apples and the weight of the apples alone.

Question: Which statement is true?

The equation a= 7.5t models the relationship.

If the total weight of the box is 15 lb, then the weight of the apples is 13.5 lb.

If the total weight of the box is 20 lb, then the weight of the apples is 21.5 lb.

To find any value of a, subtract 2.5 from the corresponding value of t

Table:
Total weight of box (lb), t: 7.5

12.5
Weight of apples (lb) a: 6
8.5

Answers

Answer:

here's the right answer- someone on a different website said the same weird thing as the person before me smh

Step-by-step explanation:

If the total weight of the box is 15 lb, then the weight of the apples is 13.5 lb.

Option (2) is correct.

What is an equation?

Equation: A declaration that two expressions with variables or integers are equal. In essence, equations are questions, and attempts to systematically identify the solutions to these questions have been the driving forces behind the creation of mathematics. Simple algebraic equations with merely addition or multiplication to differential equations, exponential equations with exponential expressions, and integral equations are examples of different types of equations. They are employed to represent a number of physics laws.

As per the given data:

The table shows the total weight of the box and the weight of the apples.

From the table:

Total weight of the box - weight of apples = weight of box

7.5 - 6 = 1.5 lb

10 - 8.5 = 1.5 lb

12.5 - 11 = 1.5 lb

If the total weight of the box is 15 lb and the weight of the apples is 13.5 lb

15 - 13.5 = 1.5 lb {weight of box}

Which satisfies the data in the table.

Hence, If the total weight of the box is 15 lb, then the weight of the apples is 13.5 lb.
