You bought 3/4 pound of fudge for 6.75. Write and solve an equation to find the cost of the fudge per pound.
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
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
Find the zeros 7x(x-11)-2(x-11)=0
(x-11)(7x-2)=0
x=11 or x=2/7
Answer:
x = [tex]\frac{2}{7}[/tex], x = 11
Step-by-step explanation:
Given
7x(x - 11) - 2(x - 11) = 0 ← factor out (x - 11) from each term
(x - 11)(7x - 2) = 0
Equate each factor to zero and solve for x
x - 11 = 0 ⇒ x = 11
7x - 2 = 0 ⇒ 7x = 2 ⇒ x = [tex]\frac{2}{7}[/tex]

A sno-cone machine priced at $139 is on sale for 20% off. The sales tax rate is 6.75%. What is the price of the sno-cone machine after the discount and sales tax?
Answer:
$127.03
Step-by-step explanation:
A snow cone machine price at $139 is on after for 20 off.
The price after discount=139-20=$199
The sale tax rate 6.75%
Price with sales tax=199+(6.75%×199)
=199+(0.0675×199)
= 199+8.03
=$127.03

Write a percent proportion for the bar diagram
shown.
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.

Marcla shoots an arrow that hits a bull's-eye 80 feet away. Before hitting the bull's-eye, the arrow reaches a

Part 1 out of 2
If the bull's-eye is considered to be at (80, 0), what function (In Intercept form) could represent the path of
the arrow If x is the horizontal distance from Marcia and h(x) represents the height of the arrow in relation
to the horizontal distance?
The function is h(x)=
Next
Answer:
See answer below
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 - 2/5xHope it helps
