Answer:
Step-by-step explanation:
These types of problems can be solved with substitution.
We just have to translate the word problem into math.
#1:
F = family, I = individual
[tex]F + I = 188\\95F + 42I = 12,507[/tex]
[tex]F = 188-I\\95(188-I) + 42I = 12507\\17860 - 95I + 42I = 12507\\-53I = -5353\\I = 101\\\\F + I = 188\\F + 101 = 188\\F = 87[/tex]
87 Families, 101 individuals
#2:
The perimeter is 899 meters. The perimeter can be defined as:
[tex]2L + 2W = P\\2L + 2W = 899[/tex]
We are also given that
[tex]2L = W - 100\\so\\2L + 2W = 899\\W- 100 + 2W = 899\\3W = 999\\W = 333\\\\L = \frac{W-100}{2} = \frac{333-100}{2} = \frac{233}{2}[/tex]
W = 333 meters, L = 233/2 meters

a university department administers a survey regardring student satisfaction based on the survey results the department provides a confidence interval estimate of 60% to 80% for student satisfaction if the department wishes to construct a confidence interval the more accurate represents the proportion of a student satisfaction how should the design be altered
Answers
Answer:
Change the confidence interval.
Step-by-step explanation:
The confidence interval should be altered . If a 95 % or 90% confidence interval is set then better results can be obtained for student satisfaction.
A 90 or 95 or 99 percent confidence interval will show a greater range of the data that lies within or without the given criteria.
95 % confidence interval does not mean that the probability is 95% . It means that we are 95% of the data lies or does not lie within the specific range.
This gives better results as compared to 60- 80 % confidence intervals.
If 95% of the students are satisfied as compared to 60% or 80% , this shows more accuracy.

An employee at an electronics store makes $12 per hour plus commission of 4.5% of her sales. This week she has sold 36 television averaging $620 each.What is her commission this week?
Answers
Answer: $1004.4
Step-by-step explanation:
Simple math
The total commission of the employee will be $1004.4 for the given sale.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
As per the given,
4.5% of commission on sales.
Total selling = 36 x 620 = $22320
4.5% of $22320 = (4.5/100)22320 = $1004.4
Hence "The total commission of the employee will be $1004.4 for the given sale".

Solve this in distributing -(5.3x-7y)-9.6
Answers
Answer:
[tex]-\left(5.3x-7y\right)\left(-9.6\right)=\:50.88x-67.2y[/tex]
Step-by-step explanation:
Given the expression
[tex]-\left(5.3x-7y\right)\times \left(-9.6\right)[/tex]
[tex]=-\left(-9.6\right)\left(5.3x-7y\right)[/tex]
Apply distributive law
[tex]a\left(b-c\right)=ab-ac[/tex]
[tex]a=-\left(-9.6\right),\:b=5.3x,\:c=7y[/tex]
so the expression becomes
[tex]=-\left(-9.6\right)\times \:5.3x-\left(-\left(-9.6\right)\right)\times \:7y[/tex]
[tex]=-\left(-9.6\right)\times \:5.3x+7\left(-9.6\right)y[/tex] ∵ [tex]-\left(-a\right)=a[/tex]
[tex]\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a,\:-\left(-a\right)=a[/tex]
[tex]=9.6\times \:5.3x-7\times \:9.6y[/tex]
[tex]=50.88x-7\times \:9.6y[/tex]
[tex]=50.88x-67.2y[/tex]
Therefore,
[tex]-\left(5.3x-7y\right)\left(-9.6\right)=\:50.88x-67.2y[/tex]

what is the slope of the line through the points (3,7) and (5,15)?
a. 2/5
b. 1/4
c. 4
d. 5/2
Answers
Answer:
C. 4
Step-by-step explanation:
The formula of slopes is: y2 - y1/x2 - x1
m = y2 - y1/x2 - x1
m = 15 - 7/5 - 3
m = 8/2
m = 4/1
m = 4
The slope of the line through the points (3,7) and (5,15) is 4 .
What is slope of line passing through two points ?The slope of a line is defined as the change in y coordinate with respect to the change in x coordinate of that line.
Δy = change in y coordinate = y2 - y1
Δx = change in x coordinate = x2 - x1
m = Δy/Δx
where,
m is the slope
According to the question
Points (3,7) and (5,15)
therefore,
(x1,y1) = (3,7)
(x2,y2) = (5,15)
Now ,
The slope of the line
Using slope formula
m = Δy/Δx
Δy = y2 - y1
Δy = 15 - 7
Δy = 8
Δx = = x2 - x1
Δx = 5 - 3
Δx = 2
Therefore,
m = [tex]\frac{8}{2}[/tex]
m = 4
Hence, the slope of the line through the points (3,7) and (5,15) is 4 .

Answer:
For Question 3, all you have to do is subtract 5 from both sides of the equation, then divide by -3, which will leave you with 5 as the answer.
-3x + 5 = -10
-3x = -15x
x = 5
-5 -5
Subtract-5 from both sides because the opposite +5 is -5 so they cancel out.
-3x=-15
3. 3
Divide -3 from both sides so they can cancel each other out. So -15 divided by -3 would equal 5 because a negative and a negative makes a positive.
Which equals:
x=5
And to check your work you can just plug in 5 into x because 5 is X.
-3(5)+5=-10
Negative 3 times 5 equals -15 and plus 5 equals -10.
-10=-10
Which mean it is right cause they are the same number (-10) but if it were to be a different number it would be wrong. That’s how you can check your work. Just plug in X into the (x) equation. hope it help!! :))

order the numbers -7/8, 7/4 -1 4/5, -13/16
Answers
Answer:
from least to greatest or what? ill do lest to greatest tho
-7/8, -13/16, -1 4/5, 7/4
Step-by-step explanation:
all of these can be converted into a fraction with a denominator of 16 so you can compare easier except for -1 4/5 but that is the highest negative number so that would be the last one you put down because it has a whole number so it is greater than one therefor being greater than the rest of the negative fractions that are less than one, but for the rest, it is just simple least to greatest *(if it is greatest to least just reverse it)*
Answer:
From least to greatest: -1 4/5, -7/8, -13/16, 7/4
Greatest to least: 7/4, -13/16, -7/8, -1 4/5
Step-by-step explanation: Start with the greatest number. This would be 7/4 since it is the only positive number in the set of numbers. Then, find a common denominator for the rest of the numbers/fractions. To save time, a common denominator of -7/8, -1 4/5 and -13/16 is 80. Then, make all the equations equivalent. To do this, I’ll just use -13/16. So, just multiply 5 by 16 and -13 by 5 to get the right fraction. The answer would be -65/80 and you would do this process for the rest of the numbers. Once your done with this explanation, just remember that a lower negative number has a higher value on the number line making it greater in a set of numbers.
