Answer:
Yes
Step-by-step explanation:
There are about 52 weeks in a year, 42,990 ÷ 52 = 826.73076 ,
1277 ÷ 12 = 106.41666
826.73076 - 106.41666 = 720.3141
720.3141 - 456 = 264.3141
Yes, one week's paycheck is enough to pay for his monthly auto loan and his monthly cost of insurance.
In mathematics, it deals with numbers of operations according to the statements.
There are 52 weeks in a year,
Income of 1 week = $42,990/52 = 826.73
So his income of Gary for 1 week is $826.73
he pays $1277 per year for auto insurance
There are 12 months in a calender year
Monthly auto insurance pay = 1277/12 = 106.42
Pay for monthly auto insurance is $106.42
and he currently has a $456 per month car loan payment
Total pay = 106.42 + 456 = $562.42
Here, their income of Gary for a week is greater than the total pay,
Thus, yes, one week's paycheck is enough to pay for his monthly auto loan and his monthly cost of insurance.

The volume of a triangular pyramid is 110 cm³. The base of the triangle is 10 cm in the height of the triangle is 6 cm. Find the height of the pyramid.
Answer:
The height of the pyramid is 11 cm.
Step-by-step explanation:
We are given the following in the question:
Volume of triangular pyramid = 110 cubic cm
Base of trianle,b = 10 cm
Height of triangle,h = 6 cm
Area of triangular base =
[tex]A = \dfrac{1}{2}\times b\times h\\\\A = \dfrac{1}{2}\times 10\times 6\\\\A = 30\text{ square cm}[/tex]
Volume of triangular pyramid =
[tex]V = \dfrac{1}{3}AH[/tex]
where H is the height of the pyramid, A is the area of triangular base.
Putting values, we get,
[tex]110 = \dfrac{1}{3}\times 30\times H\\\\H = \dfrac{3\times 110}{30}\\\\H = 11\text{ cm}[/tex]
Thus, height of the pyramid is 11 cm.

How do u define demography
Answer:Demography is the statistical study of the size, structure, and distribution of a population. This includes studying the number of births and deaths a population has as well as how that population changes over time.
Step-by-step explanation:
Merrill Lynch Securities and Health Care Retirement Inc. are two large employers in downtown Toledo, Ohio. They are considering jointly offering child care for their employees. As a part of the feasibility study, they wish to estimate the mean weekly child care cost of their employees. A sample of 10 employees who use child care reveals the following amounts spent last week.$107 $92 $97 $95 $105 $101 $91 $99 $95 $104(a) Develop a 99 percent confidence interval for the population mean. Interpret the results.
Answer:
Step-by-step explanation:
We would determine the mean an standard deviation first
Mean = (107 + 92 + 97 + 95 + 105 + 101 + 91 + 99 + 95 + 104)/10 = 98.6
Standard deviation = √(summation(x - mean)/n
n = 10
Summation(x - mean) = (107 - 98.6)^2 + (92 - 98.6)^2 + (97 - 96.6)^2 + (95 - 98.6)^2 + (105 - 98.6)^2 + (101 - 98.6)^2 + (91 - 98.6)^2 + (99 - 98.6)^2 + (95 - 98.6)^2 + (104 - 98.6)^2 = 274
Standard deviation = √(274/10) = 5.23
The confidence interval is used to determine the range of values that could possibly contain a population parameter (population mean)
Confidence interval is written in the form,
(Point estimate - margin of error, Point estimate + margin of error)
The sample mean, x is the point estimate for the population mean.
We will use the t distribution because the sample size is small and the population standard deviation is not given.
Degree of freedom, df = 10 - 1 = 9
α = 1 - 0.99 = 0.01
z α/2 = 0.01/2 = 0.005
The area to the right of z 0.005 is 0.005 and the area to the left of z0.005 is 1 - 0.005 = 0.995. Using the t distribution table,
z = 3.25
Margin of error = z × s/√n
Where
s = sample standard Deviation = 5.23
Margin of error = 3.25 × 5.23/√10 = 5.38
Confidence interval = sample mean(point estimate) ± z × σ/√n
The lower boundary of the confidence interval is
98.6 - 5.38 = 93.22
The upper boundary of the confidence interval is
98.6 + 5.38 = 103.98
We estimate with 99% confidence that the mean weekly child care cost of their employees is between $93.22 and $103.98
Also,
99% of the confidence intervals constructed in this way would contain the true value for the population mean of mean weekly child care cost of their employees.
The 99% confidence interval for the average weekly childcare cost based on this sample data is [$94.6, $102.6], which means we're 99% certain the true average cost falls within this range.
Explanation:When we are talking about a confidence interval for the population mean, we're trying to determine a range within which we're confident the true average child care cost falls, given the data we have from a sample of employees. To do this, we first have to calculate the mean (or average) child care cost and the standard deviation of our sample.
The mean weekly child care cost would be ($107 + $92 + $97 + $95 + $105 + $101 + $91 + $99 + $95 + $104) / 10 = $98.6. To calculate the standard deviation, you would subtract each data point from the mean, square the results, find the average of these squared differences, and finally take the square root. In this case, the standard deviation equates to ~5.27. Now we can use these values to calculate the confidence interval. For a 99% confidence interval with a sample size of 10, the appropriate t-value from the t-distribution table is 3.25. The confidence interval would therefore be Mean +/- t-value*(standard deviation/sqrt(n)). So the interval would be 98.6 +/- 3.25*(5.27/sqrt(10)). This calculates to an interval of [94.6, 102.6]. That means we're 99% confident the true average weekly child care cost falls between $94.6 and $102.6.

All members of our painting team paint at the same rate. If $20$ members can paint a $6000$ square foot wall in $24$ minutes, then how long would it take the $20$ members to paint a $9000$ square foot wall, in minutes?
Let x represent time taken by 20 members to paint 9000 square foot wall.
We have been given that all members of our painting team paint at the same rate. 20 members can paint a 6000 square foot wall in 24 minutes. We are asked to find the time taken by 20 members to paint 9000 square foot wall.
We will use proportions to solve our given problem.
[tex]\frac{\text{Time taken}}{\text{Area of wall painted}}=\frac{24\text{ min}}{6000\text{ ft}^2}[/tex]
[tex]\frac{x}{9000\text{ ft}^2}=\frac{24\text{ min}}{6000\text{ ft}^2}[/tex]
[tex]\frac{x}{9000\text{ ft}^2}\times 9000\text{ ft}^2=\frac{24\text{ min}}{6000\text{ ft}^2}\times 9000\text{ ft}^2[/tex]
[tex]x=\frac{24\text{ min}}{6}\times 9[/tex]
[tex]x=4\text{ min}\times 9[/tex]
[tex]x=36\text{ min}[/tex]
Therefore, it will take 36 minutes for 20 members to paint 9000 square foot wall.
Answer:
36 minutes
Step-by-step explanation:
The amount of time needed and the amount of wall to paint are directly proportional. So, when we multiply the amount of wall to paint by 4/3 (going from 6000 square feet to 9000 square feet), we multiply the time needed by 9000/6000 = 3/2. Therefore, the 20 members need 24 * 3/2 = 36 minutes to paint the 9000 square foot wall.

The government of a large city needs to determine whether theâ city's residents will support the building of a new Middle School. The government decides to conduct a survey of a sample of theâ city's residents. Which one of the following procedures would be the most appropriate for obtaining a sample of theâ city's residents?a. Survey a random sample of the employees and inmates at the old jail. b. Survey every fifth person who walks into City Hall on a given day. c. Survey a random sample of persons within each geographic region of the city. d. Survey the first 200 people listed in the cityâs telephone directory.
Answer:
c. Survey a random sample of persons within each geographic region of the city.
Step-by-step explanation:
Since the government intends to conduct the survey on a sample of the city residents. The sample must be random and a true representation of those who live in the city. It is therefore important that the survey is carried out on a random sample of persons within each geographic region of the city.
All other options are not true representation of the city's population.
The most appropriate procedure for obtaining a sample of a city's residents that will support the new Middle School is to survey a random sample of persons within each geographic region of the city.
The government of a large city needs to determine whether the city's residents will support the building of a new Middle School. When deciding on the most appropriate procedure for obtaining a sample of the city's residents, the goal is to ensure that the sample is both random and representative of the entire population. Out of the given options:
Survey a random sample of the employees and inmates at the old jail would not be representative of the entire city.
Survey every fifth person who walks into City Hall on a given day could have selection bias and might not be a random sample.
Survey a random sample of persons within each geographic region of the city would likely be the most appropriate method, as it ensures that all areas of the city are represented.
Survey the first 200 people listed in the city’s telephone directory could result in a sample that is not random, as it excludes those not listed in the directory or those with unlisted numbers.
Therefore, the best option among those presented is to survey a random sample of persons within each geographic region of the city. This would provide a more accurate reflection of the city's residents' opinions regarding the new Middle School.

A percent is a rate in which the first term is compared to
A. 100
B. itself
C. 1
D. 0
A unit rate is a rate in which the first term is compared to
A. 0
B. 100
C. itself
D. 1
From what we know about percentages and unit rates, the correct options are:
1) 100
2) 1
What is a percent?
Suppose we have an amount A, this would be the 100%.
If we want to know how much a quantity B represents, compared to A, we have:
A = 100%
B = x
where x is a percentage, to find the value of x we compute:
x = (B/A)*100%
While there is a dependence on A, we actually are comparing the term with 100 (because A represents a 100%), so the correct option is A: 100.
What is a unit rate?We define the unit rate as the rate for a unit of something.
for example, if we know that
2 apples cost $3
The unit rate per apple is:
U = $3/2 = $1.5
Meaning that each apple costs $1.5
So to get the unit rate, we need to compare the first term with 1 (a unit). So the correct option is D.

A cell phone is on sale for 30% off. If the sale price is $239.89, what is the original price?
Answer:
$342.7
Step-by-step explanation:
Let the sale price be x.
So,
x - 30% of x = $239.89
x - 30/100*x = 239.89
(100x-30x)/100 = 239.89
70x = 239.89 *100
x = 23989/70
x = $342.7
sale price = $342.7
Answer:
342.70
Step-by-step explanation:
Since 100%-30%=70% our equation will be:
0.70x=239.89
x=original price
0.70x=239.89
/0.70 /0.70
Divide both sides by 0.70
x=342.7

Paul has a stock portfolio worth $21,000. His home is valued at $365,000. His car is valued at $19,000. He owes $362,000 on his mortgage and $16,250 on his car loan. His credit card debt is $11,750. He owes student loans of $17,900. Paul says that because the value of his home and his car exceed their loans and his stock portfolio exceeds his credit card and student loan debt, he has a positive net worth. Complete the explanation as to whether his statement is true or not. Paul's stock portfolio the total of his credit card and student loan debt. His net worth is dollars. Therefore, Paul has a net worth, and his statement is .
Answer:
Paul has negative worth of $2,900
His statement is invalid as he did not consider all assets and debts in aggregate.
Step-by-step explanation:
The net worth of Paul is the total asset owned by him less the total of debts owed by him.
Paul's total assets can computed thus:
Stock portfolio $21,000
Home worth $365,000
Car worth $19,000
Total assets $405,000
Paul's total debts can be computed as follows:
Mortgage loan $362,000
Car loan $16,250
credit card debt $11,750
Student loan $17,900
Total debts $407,900
The amount of debts owed by Paul is $2,900($405,000-$407,900) more than his asset worth,which implies that Paul is indebted to the tune of $2,900,hence has negative worth.
Paul's statement is false; he has a negative net worth.
Explanation:Paul's statement is true, he has a positive net worth.
To calculate Paul's net worth, we subtract his debts from the total value of his assets:
Value of his home ($365,000) minus mortgage ($362,000) = $3,000 equityValue of his car ($19,000) minus car loan ($16,250) = $2,750 equityValue of his stock portfolio ($21,000) minus credit card debt ($11,750) and student loan debt ($17,900) = -$8,650By adding up all his equities, we get $3,000 + $2,750 + (-$8,650) = -$2,900. Therefore, Paul has a negative net worth and his statement is false.

Answer:
a = -1 and a = 4
Step-by-step explanation:
∛a³ + 4a² -3 = a + 1
a³ + 4a² - 3 = (a + 1)³
a³ + 4a² -3 = a³ + 3a² + 3a + 1
a² - 3a -4
(a + 1) (a - 4)
a + 1 = 0
a = -1
a -4 = 0
a = 4
Answer:
a = -1, a=4
Step-by-step explanation:
( a^3 +4a^2 -3) ^1/3 = a+1
We need to cube each side to get rid of the radical
( a^3 +4a^2 -3) ^1/3 ^3 = (a+1)^3
( a^3 +4a^2 -3) = (a+1)^3
Using the formula (x+y)^3=x^3+3x^2y+3xy^2+y^3
we can expand (a+1)^3 to a^3+3a^2+3a+1
( a^3 +4a^2 -3) =a^3+3a^2+3a+1
Moving all the terms to the left hand side
( a^3 +4a^2 -3) -(a^3+3a^2+3a+1) =a^3+3a^2+3a+1-(a^3+3a^2+3a+1)
Distribute the minus sign
( a^3 +4a^2 -3) -a^3-3a^2-3a-1 =0
Combine like terms
a^2 -3a-4 =0
Factor
(a-4) (a+1) =0
Using the zero product property
a-4 =0 a+1=0
a=4 a=-1
Check since we cubed each side for extraneous solutions
( a^3 +4a^2 -3) ^1/3 = a+1
a=4
( 4^3 +4 *4^2 -3) ^1/3 = 4+1
(64 +64 -3) ^1/3 =5

city X has a population of 3 times 10^5 and city Y has a population of 6 times 10^6. Which statement correctly describes the relationship between the population of city X and city Y
Answer:
The population of city Y is 20 times than that of city X.
Step-by-step explanation:
Given:
City X has a population of 3 times 10^5
City Y has a population of 6 times 10^6.
Question asked:
Which statement correctly describes the relationship between the population of city X and city Y?
Solution:
If we will be able to find the number of times the population of city Y more than that of city X, it will be the best and easy to understand relationship between the population of these two towns:
And we can easily calculate by dividing the population of city Y by population of city X.
[tex]=\frac{6\times10^{6} }{3\times10^{5}} \\ \\ =\frac{6\times10^{6-5} }{3}\ (\frac{a^{m} }{a^{n} }= a^{m-n} )[/tex]
[tex]=\frac{6\times10^{1} }{3} \\ \\ =\frac{60}{3} \\ \\ =20\ times[/tex]
Thus, the population of city Y is 20 times than that of city X.
City Y's population is 20 times larger than that of city X. This is determined by dividing City Y's population by City X's.
Explanation:The relationship between the populations of city X and city Y can be understood by comparing the numbers provided: 3 times 10^5 (or 300,000) for city X and 6 times 10^6 (or 6,000,000) for city Y. It's clear that city Y has a significantly larger population. In fact, city Y's population is 20 times larger than that of city X.
This is calculated by dividing city Y's population (6,000,000) by city X's population (300,000), getting the result 20.

So,
Minimum number of pennies Hannah have = 10
Final answer:
Hannah can have a minimum of 10 pennies along with her 11 nickels to make at least $0.65, while having a maximum of 25 coins in total.
Explanation:
Hannah has a maximum of 25 coins and among them, she has 11 nickels. Since she has a minimum combined worth of $0.65, we can calculate the minimum number of pennies she could have. One nickel is worth $0.05, so 11 nickels have a combined worth of $0.55 (11 times $0.05). To reach at least $0.65, we need at least $0.10 more.
A penny is worth $0.01, so to make up the additional $0.10, Hannah would need a minimum of 10 pennies. Therefore, with 11 nickels already accounted for, and the rest being pennies to reach $0.65, Hannah could have a minimum of 10 pennies. She cannot have more than 25 coins in total, so the number of pennies must also not exceed the limit of 25 total coins when added to the number of nickels she has. Since 11+10=21, this is less than the maximum of 25 coins, and thus, it is possible for Hannah to have a minimum of 10 pennies.

Find the gradient of the line that is perpendicular to the line 2y=3+5x
The gradient of the line that is perpendicular to the line 2y = 3 + 5x is found to be -0.4, after converting the given equation to slope-intercept form and determining the negative reciprocal of the original slope.
Explanation:To find the gradient of a line that is perpendicular to the given line 2y = 3 + 5x, we first need to put the given equation in slope-intercept form (y = mx + b). By dividing everything by 2, we get y = 2.5x + 1.5, where the gradient (or slope) of this line is 2.5. Since perpendicular lines have slopes that are negative reciprocals of each other, the slope of the line perpendicular to the given one is -1/2.5, which simplifies to -0.4. Therefore, the gradient of the line that is perpendicular to the line 2y = 3 + 5x is -0.4.
