Hershey's bar were purchased at $7 per dozen and sold at $1.25 each. Find the profit on 15 dozen Hershey's bar.
Answer:
[tex]Profit = \$120[/tex]
Step-by-step explanation:
Given
[tex]Cost\ Price = \$7[/tex] per dozen
[tex]Selling\ Price = \$1.25[/tex]
Required
Determine the profit on 15 dozen
First, we need to determine the selling price of 1 dozen.
[tex]Selling\ Price = \$1.25 * 12[/tex]
[tex]Selling\ Price = \$15[/tex]
Next, we calculate the profit on a dozen
[tex]Profit = Selling\ Price - Cost\ Price[/tex]
[tex]Profit = \$15 - \$7[/tex]
[tex]Profit = \$8[/tex]
Profit on 15 dozen is:
[tex]Profit = 15 * \$8[/tex]
[tex]Profit = \$120[/tex]
One and a half plus 1/8 =?
Answer:
1/2+1/8=5/8
Step-by-step explanation:
The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.
LCD(1/2, 1/8) = 8
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.
(1/2×4/4)+(1/8×1/1)=?
Complete the multiplication and the equation becomes
4/8+1/8=?
The two fractions now have like denominators so you can add the numerators.
Then:
4+1/8=5/8
This fraction cannot be reduced.
Therefore:
1/2+1/8=5/8

the difference between two numbers is 10 and their sum is four times the smaller number. find the two numbers
Answer:
The smaller number is 5.
The bigger number is 15.
Step-by-step explanation:
Let the smaller number be x and the bigger number be x+10.
x+x+10 = 4x
2x+10 = 4x
10 = 4x-2x
2x = 10
x = 10÷2
= 5
x+10 = 5+10
= 15

The graph shows a relationship between the size of 18 households and the average amount of time, in hours, each member of the household spends on chores per week. Which equation best models this data set?
A. y = 0.34x + 5.19
B. y = -0.34x - 5.19
C. y = 0.34x - 5.19
D. y = -0.34x + 5.19
Answer:
Option (D)
Step-by-step explanation:
Equation to represent the household expenditure per week will be in the form of,
y = mx + b
Where m = slope of the line
b = y-intercept
From the graph attached,
Since, line of best fit touches the positive side of the y-axis, y-intercept will be positive.
Since, y-values on the graph are decreasing with the increase in the x-values,
Slope of the graph will be negative.
[Slope = [tex]\frac{\text{Rise}}{\text{Run}}[/tex], Since rise of the line is negative and run is positive, slope will be negative]
By these properties equation of the linear graph will be,
y = -0.34x + 5.19
Option (D) will be the correct option.
The equation that best models this data set is y = -0.34x + 5.19
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the slope of the line and b is the y intercept.
Let y represent the time spent on chores for x household members.
From the graph, the line passes through (3, 4.25) and (8, 2.5). Hence:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-4.25=\frac{2.5-4.25}{8-3}(x-3) \\\\y-4.25=-0.35(x-3)\\\\y=-0.34x+5.2[/tex]
The equation that best models this data set is y = -0.34x + 5.19

Consider the two functions given below. What is the y-intercept of g? A. (0,14) B. (0,4) C. (0,9) D. (0,-5)
Note: You probabily forgot to mention the two function. While after some research, I was able to find two functions based on which I would like to solve your query.
Answer:
The y-intercept of the equation will be (0, 4).
Step-by-step explanation:
Considering the assuming functions f(x) and g(x).
[tex]f(x) = -3x - 5[/tex]
[tex]g(x) = f(x)+9[/tex]
So,
[tex]g(x) = (-3x-5)+9[/tex] ∵ [tex]g(x) = f(x)+9[/tex]
[tex]g(x) = -3x+4[/tex]
Now, finding the y-intercept
so putting x = 0 in function g(x)
[tex]g(x) = -3(0)+4[/tex]
[tex]g(x) = 0+4[/tex]
[tex]g(x) = 4[/tex]
Therefore, the y-intercept of the equation will be (0, 4).

Autumn invested $2,800 in an account paying an interest rate of 6.2% compounded
monthly. Assuming no deposits or withdrawals are made, how much money, to the
nearest ten dollars, would be in the account after 8 years?
Answer: There would be $4590 (approx.) in the account after 8 years.
Step-by-step explanation:
Formula to calculate accumulated amount if compounded monthly :
[tex]A= P(1+\dfrac{r}{12\times100})^{12t}[/tex], where P+ principal value, r = rate of interest , t = time.
Given: P=$2,800 , r = 6.2%
t= 8 years
Substitute all values in the formula , we get
[tex]A=2800(1+\dfrac{6.2}{1200})^{12\times8}\\\\=2800(1+0.005167)^{96}\\\\=2800(1.005167)^{96}\\\\=2800(1.64009619996)=4592.2693\approx4590\text{ [Rounded to the nearest ten dollars] }[/tex]
Hence, There would be $4590 (approx.) in the account after 8 years.

A school keeps track of the percentage of scholars who pack lunch versus buy lunch. On Monday, 80% of scholars packed lunch. On Tuesday, 70% of the scholars who packed lunch do so again, and 50% of those who bought lunch on Monday pack lunch on Tuesday. Assume all scholars either pack lunch or buy lunch. Find the percent change in the number of scholars who bought lunch from Monday to Tuesday, and indicate whether this was an increase or decrease.
Answer:
Increase by 10% of students that bought lunch.
Step-by-step explanation:
I think the percent change was by 10%. Because 10% of those students who packed lunched on Monday did not pack lunch on Tuesday, and assuming that they either buy or pack it that means that 10% more students bought lunch.

) If the standard deviation of a random variable X is 15 and a random sample of size n=15 is obtained, what is the standard deviation of the sampling distribution of the sample mean?
Answer:
3.8731
Step-by-step explanation:
The standard deviation of the sampling distribution of the sample mean is also called the standard error of the mean expressed as;
SM = s/√n
s is the standard deviation of the random variable X
n is the sample size
Given
s = 15
n = 15
Required
Standard deviation of the sampling distribution of the sample mean.
Substituting the given parameters into the expression above;
SM = 15/√15
SM = 15/3.8729
SM = 3.8731
Hence the standard deviation of the sampling distribution of the sample mean is 3.8731
