The simple interest Lori would pay if the loan was not amortized and the entire loan was paid at the end of 3 years is $ 1,350.
It is given in the question that:-
Principal = $15,000
Time period = 3 years
Interest rate = 3 %
Total interest paid by Lori, if the loan was amortized = $ 704.
We have to find the simple interest Lori would pay if the loan was not amortized and the entire loan was paid at the end of 3 years.
We know that,
Simple interest = (Principal*Rate*Time)/100
Hence,
Simple interest = (15000*3*3)/100 = $ 1350.

It would take 180 minutes to fill a swimming pool using the water from 5 taps.
a) How many minutes will it take to fill the pool if only 3 of the taps are used?
b) An assumption being made in my working
is that all the taps are flowing at the same
It will take 300 minutes to fill the pool if only 3 taps are used
How to determine the number of minutes it will take to fill the pool?From the question, we have the following parameters that can be used in our solution:
Number of taps = 5 taps
Number of minutes = 180 minutes
From the above parameter, we can calculate the constant of proportionality
The constant of proportionality is calculated as
Constant of proportionality = Number of taps * Number of minutes
Substitute the known values in the above equation
So, we have the following equation
Constant of proportionality = 5 * 180
Evaluate the quotient
Constant of proportionality = 900
The number of minutes it will take to fill the pool is then calculated as
Constant of proportionality = Number of taps * Number of minutes
Where
Constant of proportionality = 900
Number of taps = 3
Substitute the known values in the above equation
So, we have the following equation
900 = 3 * Number of minutes
This gives
Number of minutes = 900/3
Evaluate
Number of minutes = 300
Hence, the number of minutes is 300 minutes

joey and chloe and their daughter zoe all have the same birthday. joey is 11 year older than chloe, and zoe is exactly 11 year old today. today is the first of the 99 birthdays on which chloe's age will be an integral multiple of zoe's age. what will be the sum of the two digits of joey's age the next time his age is a multiple of zoe's age?
The sum of the two digits of Joey's age the next time his age is a multiple of Zoe's age is of 11, and this measure was found using a system of equations.
What is the system of equations?The variables for the system of equations in this problem are given as follows:
Variable x: Joey's age.Variable y: Chloe's age.Variable z: Zoe's age.Joey is one year older than Chloe, hence:
x = y + 1.
Zoe is exactly one year old, hence:
z = 1.
The difference between the ages of Chloe's and Zoe's have 9 factors. Numbers with nine factors have the following format:
x² x y² , with different x and y.
These numbers have to be different of 1, due to Zoe's age, hence the smallest number is given as follows:
2² x 3² = 4 x 9 = 36.
Since the difference is of 36 years old, so the ages are as follows:
Zoe: 1 year old. Chloe: 37 years old.Joey: 38 years old.The next time this will happen is in 36 years, hence Joey's age will be of:
36 + 38 = 74 years old.
The sum of the digits will be of:
7 + 4 = 11.

suppose you have a sample of 29 women over 35 who have not previously given birth who exercise daily, and who have an average duration of labor of 17.3 hours and a sample variance of 37.2 hours. you want to test the hypothesis that women over 35 who have not previously given birth and who exercise daily have a different duration of labor than all women over 35 who have not previously given birth.
There is not enough evidence to support the claim that women who exercise daily have a significantly different duration of labor than all women.
Standard error sm = 1.634
Test statistic t = 1.102
P-value = 0.28
This is a hypothesis test for the population mean.
The claim is that women who exercise daily have a significantly different duration of labor than all women.
Then, the null and alternative hypothesis are
[tex]H_{0}[/tex] : μ=16
[tex]H_{0}[/tex] : μ≠ 16
The significance level is 0.05.
The sample has a size n=29.
The sample mean is M=17.8.
As the standard deviation of the population is not known, we estimate it with the sample standard deviation, that has a value of s=√77.4=8.8.
The estimated standard error of the mean is computed using the formula:
[tex]s_{M}[/tex] = [tex]\frac{s}{\sqrt{n} }[/tex] = [tex]\frac{8.8}{\sqrt{29} }[/tex]= 1.634
Then, we can calculate the t-statistic as
t=(M-μ)/(s/[tex]\sqrt{n}[/tex])=(17.8-16)/1.634)=1.102
The degrees of freedom for this sample size are:
df=n-1=29-1=28
This test is a two-tailed test, with 28 degrees of freedom and t=1.102, so the P-value for this test is calculated as (using a t-table):
[tex]P_{value}[/tex]=2.P(t≥1.102)=0.28
As the P-value (0.28) is bigger than the significance level (0.05), the effect is not significant.
The null hypothesis failed to be rejected.
There is not enough evidence to support the claim that women who exercise daily have a significantly different duration of labor than all women

What is depreciation?An asset loses value over time as a result of use, damage, or obsolescence. Depreciation is the measurement for this decline. Depreciation, or a decline in asset value, can be brought on by a variety of other variables, such as bad market conditions, etc. Depreciation is the estimated decrease in value of fixed assets over the course of a fiscal year. Large lump sum purchases are made for tangible things like real estate, machinery, vehicles, and so forth.
Given Data
An automobile purchased for $34,000 is worth $2200 after 6 years.
Annual depreciation = [tex]\frac{34000-2200}{6}[/tex]
Annual depreciation = [tex]\frac{31800}{6}[/tex]
Annual depreciation = 5300
In 3 years depreciation would be

A. y = 26x - 5
B. y = 5x + 26
C. y = 26x + 5
D. y = 5x - 26
Answer:
B) y= 5x + 26
Step-by-step explanation:
if susie starts with 26 rocks and adds 5 rocks each month and x=months then the correct option is Option B
Answer: y = 5x+26 (choice B)
==========================================
Explanation:
The equation y = mx+b is in slope intercept form
m = slope
b = y intercept
The y intercept is the starting amount. In this case, she starts with b = 26 rocks. The m = 5 refers to the fact she adds 5 rocks per month. Each time x goes up by 1, y goes up by 5. Think of slope = rise/run = 5/1
rise = 5 = go up by 5 rocks
run = 1 = each time you go up by 1 month

If green beans have 7 grams of carbohydrates and 30 calories per half cup serving and if french fried shrimp have 9 grams of carbohydrates and 190 calories per three-ounce serving, how many servings of green beans and shrimp should he use?
There are 16 half-cup servings of beans and 4, three-ounce servings of shrimp.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Let x represents number of half-cup servings of beans
Let y represents number of 3 ounce servings of shrimp
We have a system of equations, one for carbs and one for calories;
7x + 9y = 150
30x + 190y = 1400
Now,
30(7x + 9y) = 30(150)
-7(30x + 190y) = -7(1400 )
210x + 270y = 4440
-210x - 1330y = -8680
-1060y = -4240
y = 4
Then substitute we get;
7x + 9y = 150
7x + 9(4) = 150
7x + 36 = 150
7x = 112
x = 16

A solution of NaOH is a really strong base, so, when it's dissolved in water to form a solution, it dissociates completely in it's ions: and its
pH = 14.8344 and rounded it will be 14.8
it dissociates completely in it's ions:
NaOH -------> Na⁺ + OH⁻
So, to calculate the pH, we first need to calculate the OH concentration. As it was stated before, a strong base like this, it will dissociate completely so the concentration of OH will be the same concentration of NaOH:
[OH⁻] = 6.83 M
The pH is calculated with the following expression:
14 = pH + pOH
So, with the OH we can calculate the pOH, and then, the pH:
pOH = -log[OH⁻]
pOH = -log(6.83) = -0.8344
So the pH:
pH = 14 - pOH
pH = 14 - (-0.8344)
pH = 14.8344 and rounded it will be 14.8
