13 is the square root of what number
Answer:
169
Step-by-step explanation:
Square root means what number times its self is a different number. In this case, 13 times 13 = 169 so 13 times itself is 169.
169 is the number whose square root is 13.
Given data ,
Let the number be represented as A
Now , the value of A is represented as the radical form
The square root of a number is the value that, when squared, gives the original number.

a hemispheric bowl with radius 25 contains water whose depth is 10. what is the area of the water's surface?
The area of the water's surface is approximately 981.25 square units.
Since the water depth is 10, the water fills up half of the hemispheric bowl. Therefore, we need to find the surface area of a circle with radius 25 (the base of the hemisphere) and divide it by 2.
The surface area of a circle with radius r is given by A = πr^2. So, the surface area of the circle with radius 25 is:
A = π(25)^2 = 625π
Dividing by 2, we get
625π/2
So the surface area of the water's surface is 625π/2 square units.
Approximating the value of π as 3.14, we get:
625π/2 ≈ 625(3.14)/2 ≈ 981.25

Determine if the following statements are true or false, and explain your
reasoning. If false, state how it could be corrected.
(a) If a given value (for example, the null hypothesized value of a parameter) is within a 95% confidence interval, it will also be within a 99% confidence interval.
(b) Decreasing the significance level (\alpha) will increase the probability of making a Type 1 error.
(c) Suppose the null hypothesis is\mu= 5 and we fail to reject H0. Under this scenario, the true population mean is 5.
(d) If the alternative hypothesis is true, then the probability of making a Type 2 error and the power of a test add up to 1.
(e) With large sample sizes, even small differences between the null value and the true value of the parameter, a diff
erence often called the effect size, will be identified as statistically signiffcant.
(f) A cutoff of\alpha= 0.05 is the ideal value for all hypothesis tests.
a) False. the null hypothesized value could not fall within a 99% confidence interval . b) false ; c) false ; d) true ; e) true ; f) false.
(a) False. If a given value (for example, the null hypothesized value of a parameter) is within a 95% confidence interval, it will not always be within a 99% confidence interval.
The reason for this is that a 99% confidence interval is wider than a 95% confidence interval.
Hence, the null hypothesized value could fall within a 95% confidence interval but not within a 99% confidence interval.
(b) False. Decreasing the significance level (α) will reduce the probability of making a Type 1 error, not increase it. A Type 1 error occurs when we reject a true null hypothesis.
By decreasing the significance level, we make it more difficult to reject the null hypothesis, which reduces the probability of a Type 1 error.
(c) False. Suppose the null hypothesis is μ = 5 and we fail to reject H0. Under this scenario, we cannot conclude that the true population mean is 5.
The data may be consistent with a range of population means, including means that are different from 5.
(d) True. If the alternative hypothesis is true, then the probability of making a Type 2 error and the power of a test add up to 1. Power is defined as the probability of rejecting a false null hypothesis.
If the alternative hypothesis is true, then the null hypothesis is false, and the probability of rejecting it (i.e., the power) is equal to 1 minus the probability of failing to reject it (i.e., the Type 2 error rate).
(e) True. With large sample sizes, even small differences between the null value and the true value of the parameter, a difference often called the effect size, will be identified as statistically significant.
This is because large sample sizes increase the precision of our estimates, which makes it easier to detect even small differences.
(f) False. A cutoff of α = 0.05 is not the ideal value for all hypothesis tests. The choice of α depends on several factors, including the consequences of a Type 1 error and the sample size.
For example, if the consequences of a Type 1 error are severe, then a lower value of α may be more appropriate. Similarly, if the sample size is very large, then a lower value of α may be necessary to maintain the Type 1 error rate.

Suppose a principal of 5500 is placed in a bank account paying interest of 6% p.a. compounded weekdy if no mociey the account, how long will it take for the account balance to reach 5700 ? Note: round your answer to 2 decimal places A cotrect atswer is 5.62, which can be typed in as folfowit 5.62=
The principal amount of $5500 is invested in a bank account with an interest rate of 6% per annum, compounded weekly.
The question asks how long it will take for the account balance to reach $5700. The correct answer, rounded to two decimal places, is 5.62.
To calculate the time it takes for the account balance to reach $5700, we can use the compound interest formula:
A = P(1 + r/n)^(n*t)
Where:
A is the final account balance
P is the principal amount
r is the interest rate (in decimal form)
n is the number of compounding periods per year
t is the time in years
In this case, the principal amount P is $5500, the interest rate r is 6% (or 0.06), and the account balance A is $5700. We need to solve for t, the time it takes for the account balance to reach $5700.
5700 = 5500(1 + 0.06/52)^(52*t)
To solve for t, we can take the logarithm of both sides:
log(5700/5500) = 52*t*log(1 + 0.06/52)
Using a calculator, we can solve for t:
t = log(5700/5500) / (52*log(1 + 0.06/52))
Calculating the above expression will give us the time t in years. Rounded to two decimal places, the correct answer is 5.62.

George and Wanda received $31,100 of Social Security benefits this year ($12,000 for George; $19,100 for Wanda). They also received $5,300 of interest from jointly owned City of Ranburne Bonds and dividend income.
What amount of the Social Security benefits must George and Wanda include in their gross income under the following independent situations?
Note: Do not round intermediate calculations. Round your final answers to the nearest whole dollar amount. Leave no answer blank. Enter zero if applicable.
Required:
George and Wanda file married joint and receive $9,750 of dividend income from stocks owned by George.
George and Wanda file married separate and receive $9,750 of dividend income from stocks owned by George.
George and Wanda file married joint and receive $34,200 of dividend income from stocks owned by George.
George and Wanda file married joint and receive $17,100 of dividend income from stocks owned by George.
George and Wanda file married joint and receive $9,750 of dividend income from stocks owned by George.
So the combined social security benefits that they have received in a year is $31,100.Now the provisional income is calculated which is defined as the sum of social security benefits received and all other taxable income. Provisional income is calculated as follows:
Provisional income = social security benefits + all other taxable income Provisional income for George and Wanda can be calculated as: Provisional income = $31,100 (social security benefits) + $5,300 (interest from jointly owned City of Ranburne Bonds and dividend income) + $9,750 (dividend income from stocks owned by George) Provisional income = $46,150 Now the taxable amount of social security benefits will be calculated.
Taxable social security benefits = lesser of (50% × social security benefits) or [50% × (provisional income − base amount)] Base amount for married individuals filing a joint return = $32,000 Now taxable social security benefits for George and Wanda will be calculated as follows: Taxable social security benefits for George = lesser of (50% × $12,000) or [50% × ($46,150 − $32,000)] Taxable social security benefits for George = $1,075 Taxable social security benefits for Wanda = lesser of (50% × $19,100) or [50% × ($46,150 − $32,000)] Taxable social security benefits for Wanda = $5,075
In this question, we need to determine the amount of social security benefits that George and Wanda must include in their gross income under different independent situations. The calculation of taxable social security benefits will depend on the type of return that they file and the total dividend income that they receive.In the first situation, George and Wanda file a married joint return and receive $9,750 of dividend income from stocks owned by George. The provisional income for George and Wanda is calculated by adding all taxable income to the social security benefits. The formula for calculating the provisional income is Provisional income = social security benefits + all other taxable income. The provisional income for George and Wanda is $46,150. The taxable amount of social security benefits is calculated as per the IRS guidelines, which state that the taxable amount will be the lesser of 50% of the social security benefits or 50% of the provisional income minus the base amount. The base amount for married individuals filing a joint return is $32,000. The taxable social security benefits for George are $1,075, and for Wanda, they are $5,075.In the second situation, George and Wanda file a married separate return and receive $9,750 of dividend income from stocks owned by George. The calculation of taxable social security benefits will be different in this case as the base amount for married individuals filing a separate return is $0. The provisional income for George and Wanda is $46,150. The taxable social security benefits for George are $1,075, and for Wanda, they are $5,075.In the third situation, George and Wanda file a married joint return and receive $34,200 of dividend income from stocks owned by George. The provisional income for George and Wanda is $79,050. The taxable social security benefits for George are $7,700, and for Wanda, they are $9,925.In the fourth situation, George and Wanda file a married joint return and receive $17,100 of dividend income from stocks owned by George. The provisional income for George and Wanda is $62,950. The taxable social security benefits for George are $3,925, and for Wanda, they are $7,050.
Thus, the amount of social security benefits that George and Wanda must include in their gross income is different in each independent situation. The calculation of taxable social security benefits depends on the type of return they file and the total dividend income they receive.

5. Find the difference of the square of 65 and the square of 45
The difference between the forecourt of 65 and the forecourt of 45 is 2200.
To find the difference between the places of 65 and 45, we need to cipher each square independently and find the difference between the two results.
A number squared is attained by multiplying the figures themselves. So let's calculate the places of 65 and 45.
65 places
65 * 65 = 4225
45 places
45 * 45 = 2025
Now try to find the difference between these two places.
4225- 2025 = 2200
So the difference between the forecourt of 65 and the forecourt of 45 is 2200.
To unfold on this, consider the following
A forecourt of 65, or 4225, represents the area of a square with 65 units on each side. also, 45 places( 2025) represents the area of a square with 45 units on each side.
Abating the area of the lower forecourt( 2025) from the area of the larger forecourt( 4225) gives the area difference, which is 2200 square units.
This means that the large square corresponding to 65 places has an fresh area of 2200 square units compared to the lower square corresponding to 45 places.
In summary, the difference between the forecourt of 65 and the forecourt of 45 is 2200.

The mayor is interested in finding a 95% confidence interval for the mean number of pounds of trash per person per week that is generated in the city. The study included 241 residents whose mean number of pounds of trash generated per person per week was 37.4 pounds and the standard deviation was 8.5 pounds. Round answers to 3 decimal places where possible.
a. To compute the confidence interval use a ? t z distribution.
b. With 95% confidence the population mean number of pounds per person per week is between and pounds.
c. If many groups of 241 randomly selected members are studied, then a different confidence interval would be produced from each group. About percent of these confidence intervals will contain the true population mean number of pounds of trash generated per person per week and about percent will not contain the true population mean number of pounds of trash generated per person per week.
The population mean number of pounds per person per week is estimated to be between 35.764 pounds and 38.036 pounds.
a. To compute the confidence interval, we will use a t-distribution.
b. With 95% confidence, the population mean number of pounds per person per week is between **35.764 pounds** and **38.036 pounds**.
To calculate the confidence interval, we can use the formula:
Confidence Interval = Sample Mean ± (Critical Value) * (Standard Deviation / sqrt(Sample Size))
Given that we have a sample size of 241 residents, a sample mean of 37.4 pounds, and a standard deviation of 8.5 pounds, we need to determine the critical value associated with a 95% confidence level using the t-distribution. The degrees of freedom for this calculation are equal to the sample size minus 1, which is 240.
Looking up the critical value for a 95% confidence level and 240 degrees of freedom in the t-distribution table or using a statistical calculator, we find the critical value to be approximately 1.97.
Plugging in the values into the formula, we have:
Confidence Interval = 37.4 ± (1.97 * (8.5 / sqrt(241)))
Calculating this expression, we find:
Confidence Interval ≈ 37.4 ± 1.122
Lower Limit = 37.4 - 1.122 ≈ 36.278 pounds
Upper Limit = 37.4 + 1.122 ≈ 38.522 pounds
Therefore, with 95% confidence, the population mean number of pounds per person per week is estimated to be between 35.764 pounds and 38.036 pounds.
c. If many groups of 241 randomly selected members are studied, then approximately **95%** of these confidence intervals will contain the true population mean number of pounds of trash generated per person per week, and approximately **5%** will not contain the true population mean. This is due to the nature of confidence intervals, which provide an estimated range for the population parameter with a certain level of confidence.

Rigid transformation is the procedures required to resize or reshape a given object so as to produce the required image. The types of rigid transformation are: translation, reflection, dilation and rotation.
Considering the triangles in the given question, it can be observed that:
i. Triangle ABC compared with its image, has not obeyed the principle.
ii. Clockwise rotation of triangle ABC using point C would produce triangle A'B'C'.
iii. Reflection of triangle ABC using point C as the reference point would produce its image A'B'C'.
