Answer:
Due to;
Sampling variability
Step-by-step explanation:
From the question, we have;
The percentage adults experts believe are convinced that it is more enjoyable to be married than single = 70%
The number of adults in the sample of the survey = 1,501 adults
The number of adults that responded that it is more enjoyable to be married than single = 1,126
According to the central limit theorem, the differences in the two samples and the small sizes of the samples compared to the population, the sample means is different from the population mean, therefore, the sample proportion that respond that it is more enjoyable to be married from the new sample will be different from the old sample due sampling variability because as the sample size is so small compared to the population, some samples can contain more of one category in the population than other samples leading to varying proportion
A deposit of $10,000 is made in a trust fund that pays 3.8% interest, compounbed quarterly. It is specified that the balance will be given to Abudu Charity after the money has earned interest for 40years. How much will the charity receive?
9514 1404 393
Answer:
$45,395.39
Step-by-step explanation:
The formula for an amount earning compound interest is ...
A = P(1 +r/n)^(nt)
where principal P is invested at annual rate r compounded n times per year for t years.
Using the given numbers, we have ...
A = $10,000(1 +0.038/4)^(4·40) ≈ $45,395.39
The charity will receive $45,395.39.
Frank weighs 160 pounds and is on a diet to gain 2 pounds a week so that he can make the football team. John weighs 208 pounds and is on a diet to lose 3 pounds a week so that he can be on the wrestling team in a lower weight class. If Frank and John can meet these goals with their diets, when will they weigh the same, and how much will they weigh at that time? (Hint: Solve for x and y and make sure you write a complete sentence for an answer)
Answer: If Frank and John can meet these goals with their diets , they will weigh same after 9.6 weeks and they will weigh 179.2 pounds.
Step-by-step explanation:
Let x = Number of weeks.
As per given question ,
Weight of Frank after x weeks = 160+2x (pounds)
Weight of John after x weeks = 208-3x (pounds)
When Weight of Frank= Weight of John
Weight of Frank after 9.6 weeks = 160+2(9.6) = 179.2 pounds
Weight of John after 9.6 weeks = 208-3(9.6)=179.2 pounds
Hence, If Frank and John can meet these goals with their diets , they will weigh same after 9.6 weeks and they will weigh 179.2 pounds.

Jim and bill each invest $15,000 into savings accounts that earn 3.5% interest. Jims account earns simple interests and bills account earns compound interest. After 25 years, who will earn more interest and how much more will he earn.
Answer:
Bill will earn more interest
He will earn $ 20,448.67 from his investment
Step-by-step explanation:
Firstly let us calculate Jim's earnings based on simple interest
A = P(1 + rt)
Calculation:
First, converting R percent to r
a decimal
r = R/100 = 3.5%/100 = 0.035 per year.
Solving our equation:
A = 15000(1 + (0.035 × 25)) = 28125
A = $28,125.00
The total amount accrued, principal plus interest, from simple interest on a principal of $15,000.00 at a rate of 3.5% per year for 25 years is $28,125.00 for Jim
Now let's us calculate bill's investment based on compound interest
Equation
A = P(1 + r)^t
A=15000(1+0.035)^25
A=15000(1.035)^25
A=15000*2.36324498427
A = $ 35,448.67
We see that Bill will earn
$ 20,448.67 from his investment

Answer:
x = $11
Step-by-step explanation:
5x = $55
9x = $99
2x = $22
In order to find the relationship between x and y, all we have to do is divide y by the term.
$55 ÷ 5 = 11
$99 ÷ 9 = 11
$22 ÷ 2 = 11
Therefore, each ticket sold is $11, or x = $11
find the unknown angle mesure
Answer: 1=65° and 5=43
Step-by-step explanation:
Question 1:
Angles on a straight line always add up to 180°.
So to find the angle of x on the first question you have to do 180-115=65°
You would have to use this method for questions 2, 3 and 4 as well.
Question 5:
Right angles always add up to 90° so to work out what x is you would have to do 90-47=43
You would have to use this method for questions 6, 7 and 8.

Answer:
41.29 cm²
Step-by-step explanation:
From the question,
Area of the shaded portion = Area of the circle - area of the square.
A' = πr²-L²...… Equation 1
Where A' = Area of the shade portion, r = radius of the circle, L = length of the square, π = pie
Given: r = 4 cm, L = 3 cm
Constant: π = 22/7.
Substitute these values into equation 1
A' = [(22/7)×4²]-3²
A' = 50.29-9
A' = 41.29 cm²
Hence the area of the shaded portion is 41.29 cm²

Consider a student’s work in determining the solution set of x > 2(y – 1)^2 – 2.
Test point: (2.25, 1.25)
x > 2(y – 1)^2 – 2
2.25 > 2(1.25 – 1)^2 – 2
2.25 > 2(0.25)^2 – 2
2.25 > 2(0.0625) – 2
2.25 > 0.125 – 2
2.25 > –1.875
Conclusion: The point (2.25, 1.25) satisfies the given inequality.
Solution set:
Which element, if any, shows an error in the student’s work?
There are no errors.
The conclusion statement is incorrect.
The graph of the solution set is incorrect.
The substitution of x and y values is incorrect.
Answer:
C. The graph of the solution set is incorrect.Step-by-step explanation:
Solution is right, properly substituted x- and y-values, no mistakes. Conclusion is right, the point within the solution set. The only mistake is the graph, with > sign the line of the graph is not included into solution, therefore should be dotted.There are no errors.
Incorrect (the graph)The conclusion statement is incorrect.

i need help what is x?
Answer:
square root of 109
Step-by-step explanation:
Use the Pythagorean Theorem to find x. The equation is a^2+b^2=c^2. In this case, a=3, b=10, and c=x. Plug that into the equation to get 9+100=c^2. Simplify that to get 109=c^2. Then divide each side by squared to get square root of 109=c.
