The average home price in a certain area was $272,000 in 2010. In 2020, the average home price was $299,000. What is the rate of inflation? Round to one decimal place
Answer: 0.95%
Step-by-step explanation:
Use the future value formula to calculate this with inflation as the rate by which the amount is increasing.
Future value = Amount * ( 1 + r) ^ no. of periods
299,000 = 272,000 * ( 1 + r) ¹⁰
( 1 + r) ¹⁰ = 299,000 / 272,000
( 1 + r) ¹⁰ = 1.099
1 + r = ¹⁰√1.099
r = 1.009484 - 1
r = 0.95%
use the Pythagorean theorem to find the distance between (-5,2) and (10,10)
D^2 = (x2-x1)^2 + (y2-y1)^2
D =sqrt((10+5)^2 + (10-2)^2)
D P SQRT(15^2 + 8^2)
D = sqrt(225 +64)
D= sqrt(289)
D = 17
The distance is 17

A company estimates that 0.1% of their products will fail after the original warranty period but within 2 years of the purchase, with a replacement cost of $350. If they offer a 2 year extended warranty for $28, what is the company's expected value of each warranty sold?
Answer:
The expected gain per warranty is $27.65, crazy stuff
Step-by-step explanation:
If the estimate is right, there is a 0.1% probability for each extended warranty that the company has to shell out $350 (we disregard the situation where the replacement fails too, because there is no info that lets us deal with that).
This brings us to cost for the company equal to 0.1%*$350 per warranty sold.
0.1%*$350 = 0.001*$350 = $0.35
And the company gets $28 for each warranty sold, hence they earn
$28 - $0.35 = $27.65

-7 u = -14/3. Solve for u.
Answer:
x = 2/3 is the answer. Good luck with work
Answer:
u = 2/3
Step-by-step explanation:
divide each side by -7 but remember to multiply by the reciprocal when dividing fractions:
u = -14/3 ÷ -7/1
u = -14/3 × -1/7
u = 14/21 which reduces to 2/3

The correct answer was .8 I just don't know how. Thank you.
Answer:
0.54 or 54%
Step-by-step explanation:
P( 1st but not second) = P(1st) - P(1st and Second) = 0.4 - 0.28 = 0.12 = 12%
P( 2nd but not first) = P(2nd) - P(1st and Second) = 0.7 - 0.28 = 0.42 = 42%
Probability of 1 of them (exactly one) = P( 1st but not second) + P( 2nd but not first) = 0.12 (12%) + 0.42 (42%) = 0.54 or also 54%.

At a certain university, the average attendance at basketball games has been 3125. Due to the dismal showing of the team this year, the attendance for the first 9 games has averaged only 2915 with a standard deviation of 585. The athletic director claims that the attendance is the same as last year. What is the test statistic needed to evaluate the claim
Answer:
The test statistic needed to evaluate the claim is t = -1.08.
Step-by-step explanation:
The test statistic is:
[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the expected value of the mean, s is the standard deviation of the sample and n is the size of the sample.
At a certain university, the average attendance at basketball games has been 3125. The athletic director claims that the attendance is the same as last year.
This means that [tex]\mu = 3125[/tex]
Due to the dismal showing of the team this year, the attendance for the first 9 games has averaged only 2915 with a standard deviation of 585.
This means that [tex]n = 9, X = 2915, s = 585[/tex]
What is the test statistic needed to evaluate the claim?
[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]
[tex]t = \frac{2915 - 3125}{\frac{585}{\sqrt{9}}}[/tex]
[tex]t = -1.08[/tex]
The test statistic needed to evaluate the claim is t = -1.08.
mean of 500 with a standard deviation of 100. What is the probability that a randomly selected score lies between 500 to 700?
Answer: 99.7% of data will fall within 3 standard deviations of the mean. The mean is 500 and the standard deviation is 100. ... Since we are only concerned with the scores from 500 to 700, we only want the half that is greater than the mean: 95/2 = 47.5%, or 0.475.:
Step-by-step explanation:
A recent survey reported that small businesses spend 24 hours a week marketing their business. A local chamber of commerce claims that small businesses in their area are not growing because these businesses are spending less than 24 hours a week on marketing. The chamber conducts a survey of 88 small businesses within their state and finds that the average amount of time spent on marketing is 23.2 hours a week. Assuming that the population standard deviation is 4.2 hours, is there sufficient evidence to support the chamber of commerce’s claim at the 0.05 level of significance?
Step 1 of 3:
State the null and alternative hypotheses for the test. Fill in the blank below. H0Ha: μ=24: μ⎯⎯⎯⎯⎯⎯⎯⎯24
Step 2 of 3: Compute the value of the test statistic. Round your answer to two decimal places.
Step 3 of 3: Draw a conclusion and interpret the decision.
Answer:
Following are the responses to the given choices:
Step-by-step explanation:
In step 1:
State the zero and alternate test hypotheses. Insert underneath.
[tex]H_0 : \mu = 24: H_a : \mu < 24[/tex]
[tex]H_0[/tex] Smaller companies in their region are and they spend at least 24 hours per week on the marketing of the these companies
[tex]H_1[/tex] There really is no growth for smaller firms in their area because the companies spend or less 24 hours per week on marketing.
In step 2:
Each test statistics meaning is calculated. Around two decimal places for your reply.
[tex]z=\frac{\bar{X}-\mu_{0}}{\frac{\sigma}{\sqrt{n}}}=\frac{23.2-24}{\frac{4.2}{\sqrt{88}}}=-1.787[/tex]
In step 3:
Draw a start and write the decision.
Since it is observed that [tex]z=-1.787 < z_c=-1.64[/tex] it is then concluded that the null hypothesis is rejected.
Consequently we consider that small companies in their field may not expand, as they spend or less 24 hours per week on marketing.

10. Find the area of the shaded region.
Answer:
Area = 114
Step-by-step explanation:
We first must find the area of the larger outside rectangle.
Area = length × width
15 × 8 = 120
Then we find the area of the smaller inside rectangle.
4 × 1.5 = 6
Since the small rectangle is not shaded we have to subtract its area from the larger shaded rectangle's area.
120 - 6 = 114

The roof pictured below has a rise of 10 feet and a run of 15 feet.
Run = 15 feet
Rise = 10 feet
-
What is its slope?
The slope of the considered roof which has a rise of 10 feet and a run of 15 feet is 2/3
How to find the slope?Slope of a line or straight object is the ratio of how much amount of rise occurs in correspondence to the increament in the run.
Thus, we get:
Slope = rise/ run
For this case, we're specified that:
The rise in roof = 10 ft and the run of 15 ft.
Thus, we get:
Slope = rise / run = 10/15 = [tex]\dfrac{5 \times 2}{5 \times 3} = \dfrac{2}{3}[/tex]
Thus, the slope of the considered roof which has a rise of 10 feet and a run of 15 feet is 2/3

Under her cell phone plan, Savannah pays a flat cost of $37.50 per month and $3 per
gigabyte. She wants to keep her bill at $51.90 per month. Which equation or tape
diagram could be used to represent the context if g represents the number of
gigabytes of data Savannah can use while staying within her budget?
Answer:
(51.90 - 37.50) / 3 = G
14.40 / 3 = G
4.8 = G
Savannah will be able to use 4 gigabytes to stay within her budget.
Step-by-step explanation:
Given that under her cell phone plan, Savannah pays a flat cost of $ 37.50 per month and $ 3 per gigabyte, and she wants to keep her bill at $ 51.90 per month, to determine which equation or tape diagram could be used to represent the context if g represents the number of gigabytes of data Savannah can use while staying within her budget, the following calculation should be performed:
(51.90 - 37.50) / 3 = G
14.40 / 3 = G
4.8 = G
Therefore, Savannah will be able to use 4 gigabytes to stay within her budget.
