Answer:
14.74%
Step-by-step explanation:
The formula for ANNUAL PERCENTAGE YIELD (APY) for an account that is COMPOUNDED CONTINUOUSLY is given as
APY = Pe^rt - 1
Where P = Principal
e = exponential
r = rate
t = time
Since Principal and Time was not given in the question,
APY = e^r - 1
r = 13.75% = 0.1375
APY = e^0.1375 - 1
APY = 1.147401706 - 1
APY = 0.147401706
Converting to percentage
= 0.147401706 × 100
= 14.7401706%
Approximately to 2 decimal places: 14.74%
Therefore, the annual percentage yield is 14.74%
If LN=3+8x, find LN
L•——–8•——M——6x-1——–•N
Answer:
Value of LN = 19 units
Step-by-step explanation:
Given:
LN = 3 + 8x
Find:
Value of LN
Computation:
We know that LM + MN = LN
So,
8 + 6x - 1 = LN
So,
3 + 8x = 8 + 6x - 1
3 + 8x = 7 + 6x
8x - 6x = 7 - 3
2x = 4
x = 2
So,
LN = 3 + 8x
LN = 3 + 8(2)
LN = 3 + 16
LN = 19
Value of LN = 19 units

A company sells x units of an item each day at the rate of Rs. 50. The cost of manufacturing each unit of an item is Rs. 36.50 and the dristributor demands a charge of Rs. 3.50 per unit. If the daily overhead charge is Rs. 2600, find the profit function. Also find the profit if 360 units of an item are produced and sold daily?
Answer:
Y(x) = 10x - 2600
Profit= RS. 1000
Step-by-step explanation:
Amount sold per item=RS. 50.
Cost of manufacturing= RS. 36.5
Distributor charges= Rs 3.5
Daily over head charge= RS.2600
Profit function Y (x)
Y (x) =x(50) -36.5(x) -3.5(x)-2600
Y(x) = (50-36.5-3.5)x-2600
Y(x) = 10x - 2600
If x= 360
Profit Y = 10(360) - 2600
Profit Y = 3600-2600
Profit = 1000
Profit= RS. 1000
mg+rg=2H, solve for g
Answer:
[tex]g=\frac{2\,H}{m+r}[/tex]
Step-by-step explanation:
Starting with :
m g + r g = 2 H
extract "g" as a common factor on the left of the equal sign:
g (m + r) = 2 H
Now, in order to solve for "g" , divide both sides of the equal sign by the binomial (m + r):
g = (2 H )/(m + r)
[tex]g=\frac{2\,H}{m+r}[/tex]

Answer:
{3, 4, 5, 6, 7, 8} and {8, 7, 6, 5, 3}
Step-by-step explanation:
The sets {3, 4, 5, 6, 7, 8} and {3, 4, 5, 6, 7, 8} will be constraint through {x | x < 9 and x >2} so option (A) and (C) will be correct.
What is an set?A set is a combination of specific quantities in which the meaning of each variable must be the same.
For example {1,2,3,4,5,6...} is a set of natural numbers in which each variable is representing a natural number so the overall meaning is the same among all.
Another example could be a set of the whole number like that.
Given the constraint
{x | x < 9 and x >2}
It means x should be greater than 2 and less than 9
So all possible values are
3,4,5,6,7,8
Now set associated with these number is {3, 4, 5, 6, 7, 8} and {8, 7, 6, 5, 3}.
Hence "The sets {3, 4, 5, 6, 7, 8} and {3, 4, 5, 6, 7, 8} will be constraint through {x | x < 9 and x >2}".

The data show the list and selling prices for several expensive homes. Find the regression equation, letting the first variable be the independent (x) variable. Find the best predicted selling price of a home having a list price of $ million. Use a significance level of 0.05.
Answer:
The best predicted selling price of a home having a list price of $22 million is $20.52 million.
Step-by-step explanation:
The missing data is:
List price (x) (millions of $)
(1) 1.6 (2) 4.2 (3) 2.1 (4) 1.6 (5) 2.3 (6) 4
Selling price (y) (millions of $)
(1) 2 (2) 4.6 (3) 1.8 (4) 1.9 (5) 2.4 (6) 3.6
Use Excel to perform the regression analysis.
The significance level is, α = 0.05.
The regression output is attached below.
The regression equation is:
[tex]\hat y=0.28+0.92x[/tex]
The value of t-statistic is:
t = 0.676.
The p-value is:
p-value = 0.536
Compute the predicted selling price of a home having a list price of $22 million as follows:
[tex]\hat y=0.28+0.92x[/tex]
[tex]=0.28+0.92\times 22\\\\=0.28+20.24\\\\=20.52\ \text{million}[/tex]
Thus, the best predicted selling price of a home having a list price of $22 million is $20.52 million.
Think of a problem dealing with two possibly related variables (Y and X) that you may be interested in. Share your problem and discuss why a regression analysis could be appropriate for this problem. Specifically, what statistical questions are you asking? Why would you want to predict the value of Y? What if you wanted to predict a value of Y that’s beyond the highest value of X (for example if X is time and you want to forecast Y in the future)?
Answer:
Explained below.
Step-by-step explanation:
Consider the variables height and weight.
It is usually seen that taller people are heavier than shorter people.
So a regression analysis can be used to specify this belief.
The statistical questions that are being asked here are:
What the independent and dependent variables?Are there any other factor influencing the dependent variable other than the independent variable?The variable Y is considered as the dependent variable and the variable Y is considered as the independent variable. And the main purpose of the regression analysis is to predict the value of Y when the value of X is given.
The linear regression model can be used to predict the past and future value of the dependent variables provided that the independent variables for those times are provided.

Under what circumstances can a very small treatment effect be statistically significant? Explain your response.
a) if the sample size big and the sample variance is small
b) if the sample size and the sample variance are both big
c) if the sample size is small and the sample variance is big
d) if the sample size and the sample variance are both small
Answer:
The correct answer is:
if the sample size big and the sample variance is small (a)
Step-by-step explanation:
The sample size of a study is the group of subjects that are selected from the general population and is considered an accurate representation of the population. With a large sample size, the likelihood of type I and type II errors occurring reduces. Increasing sample size allows the researcher to increase the significance level of the finding because it increases accuracy in coverage of the universal set, hence the effect accurately mirrors what goes on in the whole group. However, smaller sample size, on the other hand, does not accurately mirror the whole larger group.
The sample variance is the difference between the observed value and the true(actual). It is a measure of deviation or variability between the results and the true value. A smaller variance means increase closeness to the true value hence increase in accuracy and statistical significance.
Therefore, when the treatment effect is small but the sample size is large and variance is small, then the result is statistically significant.

0 2.6
0 2.4
0 2.2
2.3
Answer:
2.6
Step-by-step explanation:
Let us assume that the unit of measurement is centimetre (cm)
To obtain the value of A, do the following:
From the diagram above, we can say that the scale is 5 cm to 1 unit since there are 5 lines before a number.
Next, we shall determine the value of 1 cm.
5 cm = 1 unit
Therefore,
1 cm = 1/5 = 0.2 unit
This means that 1 small line is equivalent to 0.2 unit.
Now we shall determine A as follow:
A is exactly 3 lines (3 cm) after number 2.
1 cm = 0.2 unit
3 cm = 3 x 0.2 = 0.6 unit
Now, add 0.6 to 2 to obtain the value of A.
A = 2 + 0.6
A = 2.6
Therefore, A correspond to 2.6

Plewse help me idk how to do it (20 points)!!
The explicit formula for a straight line is written as y = Mx + b, where m is the slope and b is the y intercept.
The y intercept is the y value of where the line crosses the x axis. On the above picture the line crosses the x axis at -2, so the y intercept is -2
Use 2 points in the line for the slope:
Slope = change in y over the change in x:
(0,-2) (6,0)
Slope = (0- -2) / (6-0) = 2/6 = 1/3

Paulina’s father pays her $20 per month for doing chores. In April, she makes a deal with him. Rather than paying her $20, he can pay her 1¢ on the first day of the month, 2¢ on the second, 4¢ on the third, and continue each day by doubling the amount he paid on the previous day. Use the properties of exponents to write expressions for the first 5 days of the month. The, explain if Paulina will make more or less than $20 per month using this pattern.
Answer:
Step-by-step explanation:
This is a geometric sequence with first element 1 and common ratio 2:
a(n) = 1*2^(n - 1)
Thus, a(1) = 1
a(2) = 2^(2 - 1) = 2
a(3) = 2^(3 - 1) = 4
a(4) = 2 ^( 4 - 1) = 2^ 3 = 8
a(5) = 2^(5 -1) = 2^ 4 = 16
One month is approximately 30 days. Therefore,
a(30) = 2^ (30 - 1) = 2^29 = 536870912
Using this pattern, Paulina will "make" $536870.12 vs $20 via Paulina's father's plan.

The net of a square pyramid is shown
below. What is the surface area of the
pyramid?
A 100 cm2
B 136 cm2
C 172 cm2
D 192 cm2
Answer:
Option (D)
Step-by-step explanation:
Surface area of a square pyramid is determined from the formula,
Surface area = Area of the square base + 4(Area of one lateral triangular side)
Area of the base = (Side)²
= 8²
= 64 cm²
Area of one lateral triangle = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
= [tex]\frac{1}{2}(8)(8)[/tex]
= 32 cm²
Therefore, surface area of the square pyramid = 64 + 4(32)
= 64 + 128
= 192 cm²
Therefore, Option (D) will be the correct option.
