Step-by-step explanation:
if you deposit money in a savings account with an interest rate (apr) of 6.2% and the account compounds monthly, which is your annual percentage yield (apy)? convert your answer to a percent and round it to two decimal places.
The Annual Percentage Yield (APY) for the savings account with an APR of 6.2% and monthly compounding is approximately 6.22%.
To calculate the Annual Percentage Yield (APY) for a savings account that compounds monthly, we can use the following formula:
APY = (1 + r/n)^n - 1
Where:
r is the annual interest rate expressed as a decimal (6.2% = 0.062)
n is the number of times the interest is compounded per year (monthly compounding = 12)
Let's plug in the values and calculate the APY:
APY = (1 + 0.062/12)^12 - 1
APY = (1.0051667)^12 - 1
APY ≈ 0.062161 (rounded to five decimal places)
To convert the APY to a percentage and round it to two decimal places, we multiply the result by 100:
APY ≈ 6.22%
Therefore, the Annual Percentage Yield (APY) for the savings account with an APR of 6.2% and monthly compounding is approximately 6.22%. This indicates the effective annual rate of return you would earn on your savings, taking into account the compounding of interest over the course of a year.

What is median?In statistics, the median is the value separating the higher half from the lower half of a dataset. In other words, it is the middle value of a dataset when it is ordered in ascending or descending order.
Here,
To find the median time, we need to arrange the data in order from least to greatest and find the middle value.
10, 15, 30, 35, 40, 40, 45, 55, 60, 62, 64, 64, 66, 68, 70, 70, 72, 75, 75, 80, 82, 84, 90, 90, 105, 110, 120, 180
There are 28 values in the data set, so the median is the average of the 14th and 15th values:
Median = (70 + 70)/2
= 70
To find the lower quartile, we need to find the median of the lower half of the data set:
10, 15, 30, 35, 40, 40, 45, 55, 60, 62, 64, 64, 66, 68
There are 14 values in the lower half, so the lower quartile is the median of these values:
Lower quartile = (40 + 40)/2
= 40
To find the upper quartile, we need to find the median of the upper half of the data set:
72, 75, 75, 80, 82, 84, 90, 90, 105, 110, 120, 180
There are 14 values in the upper half, so the upper quartile is the median of these values:
Upper quartile = (84 + 90)/2
= 87
To find the range, we subtract the smallest value from the largest value:
Range = 180 - 10
= 170
To determine if there are any outliers in the data set, we need to calculate the interquartile range (IQR):
IQR = Upper quartile - Lower quartile
= 87 - 40
= 47
Any value that is more than 1.5 times the IQR below the lower quartile or above the upper quartile is considered an outlier.
Lower outlier threshold = Lower quartile - 1.5IQR
= 40 - 1.547
= -20.5
Upper outlier threshold = Upper quartile + 1.5IQR
= 87 + 1.547
= 160.5
To draw a box-and-whisker plot, we need to plot a box from the lower quartile to the upper quartile, with a line inside the box representing the median. We then draw whiskers extending from the box to the smallest and largest values that are not outliers. The box extends from 40 to 87, with a line at 70 representing the median. The whisker on the left extends to the smallest non-outlier value of 10, and the whisker on the right extends to the largest non-outlier value of 120.

write an equation that represents the points (2,6)(0,3) but a linear kind of an equation in any form
Answer:
y=\(\frac{3}{2} x+3\)
Step-by-step explanation:
What value of y will make the equation true?
Generally the value of y would be 34 because same two square roots of n multiplying each others would equal to n by the definition.
\( \large \boxed{ \sqrt{a} \times \sqrt{a} = ( \sqrt{a} )^{2} = a}\)
Although it is easy to predict the solution of y-value, I will be showing you how to solve the radical equation for y-term which will be useful.
\( \large \boxed{ \sqrt{a} \times \sqrt{b} = \sqrt{ab} }\)
So from the equation, convert √34 × √y to √34y
\( \large{ \sqrt{34} \times \sqrt{y} = 34} \\ \large{ \sqrt{34y} = 34}\)
Then we square both sides to get rid of the square root.
\( \large{ {( \sqrt{34y} )}^{2} = {34}^{2} } \\ \large{34y = 1156}\)
Divide both sides by 34 so we can finally isolate the y-term.
\( \large{ \frac{34y}{34} = \frac{1156}{34} } \\ \large \boxed{y = 34}\)
Hence the value of y is 34.
Answer
y = 34solve the system of linear equations.-x+y=4x+3y=4
x=-2
y=2
Explanation
\(\begin{gathered} -x+y=4\text{ Equation(1)} \\ x+3y=4\text{ Equation(2)} \end{gathered}\)
Step 1
isolate y in equation (1) and replace in equation (2)
\(\begin{gathered} -x+y=4\text{ Equation(1)} \\ \text{add x in both sides} \\ -x+y+x=4+x \\ y=4+x\Rightarrow Equation(3) \end{gathered}\)now, replace equation (3) in equation(2)
\(\begin{gathered} x+3y=4\text{ Equation(2)} \\ x+3(4+x)=4\text{ } \\ x+12+3x=4 \\ 12+4x=4 \\ \text{subtract 12 in both sides} \\ 12+4x-12=4-12 \\ 4x=-8 \\ \text{divide both sides by 4} \\ \frac{4x}{4}=-\frac{8}{4} \\ x=-2 \end{gathered}\)Step 2
now replace the x value in equation (3) to find y
\(\begin{gathered} y=4+x\Rightarrow Equation(3) \\ y=4+(-2) \\ y=4-2 \\ y=2 \end{gathered}\)I hope this helps you

Write three more equations for 1ị that are all true and all different. Use only fractions with a denominator of 3 in your equations. 1 2/3 =1 2/3 =1 2/3 =
That we added a real number (2/3) and subtracted a real number (3), but the imaginary part of the result is still (5/3)i.
First, let me clarify what 1ị represents. In mathematics, the imaginary unit i is defined as the square root of -1. Therefore, 1ị means 1 times the imaginary unit i.
To write three more equations for 1ị that are all true and all different, we can use the fact that i satisfies the equation i^2 = -1. We can also use the fact that any multiple of i, such as 2i, 3i, and so on, is also an imaginary number. Finally, we can use the fact that adding or subtracting real numbers to or from an imaginary number does not affect the imaginary part of the number.
Here are three possible equations for 1ị:
(2 + 1/3)i = 1ị + 2i
Explanation: We can add 2 times the imaginary unit i to 1 times the imaginary unit i to get 3 times the imaginary unit i, which is equal to (2 + 1/3) times the imaginary unit i.
(-1/3)i = 1ị - 4/3i
Explanation: We can subtract 4/3 times the imaginary unit i from 1 times the imaginary unit i to get -1/3 times the imaginary unit i.
(5/3)i = 1ị + 2/3 + 3i - 3
Explanation: We can add 2/3 and 3i - 3 to 1 times the imaginary unit i to get (5/3) times the imaginary unit i. Notice that we added a real number (2/3) and subtracted a real number (3), but the imaginary part of the result is still (5/3)i.

The mistake the arrangers made is in the second inequality. They considered the number of caps to be bought should be at least 5 times greater than the number of blouses, not the other way around. The correct inequality should be C
The correct answer is D) The first inequality should be s + h ≤ 1800.
The organizers made an error in the first inequality. The given inequality 10s + 8h ≤ 1800 represents the total cost of buying shirts (10s) and hats (8h) should be less than or equal to $1800. However, this does not take into account the fact that the organizers want to buy at least 5 times as many shirts as hats, as indicated by the second inequality h ≥ 5s.
The correct way to represent this constraint is by using the equation s + h ≤ 1800, which ensures that the total number of shirts and hats purchased does not exceed $1800 in cost. This is because the organizers want to make sure that the total cost of shirts and hats combined does not exceed the budget of $1800.

A statewide survey is to be made. First, the state is subdivided into counties. Seven counties are selected at random and further sampling is conventrated on these seven counties. What type of sampling is this?
a. Simple Random
b. Non-Proportional
c. Cluster
d. Stratified
The type of sampling described in the scenario is c. Cluster sampling.
Cluster sampling involves dividing the population into clusters or groups and randomly selecting some of these clusters. In this case, the state is subdivided into counties, which act as the clusters. Seven counties are selected at random, and further sampling is concentrated on these seven counties.
Cluster sampling is commonly used when it is not feasible or practical to directly sample individuals from the entire population. Instead, clusters or groups are randomly selected, and then a sample is taken from each of these clusters. This approach can be more efficient and cost-effective compared to other sampling methods, especially when the clusters are internally heterogeneous.
In this scenario, the initial random selection of the seven counties represents the cluster sampling, as subsequent sampling is focused on these specific clusters.
