Answers
====================================================
Explanation:
The formula given is
[tex]M = \frac{P*\left(\frac{r}{12}\right)*\left(1+\frac{r}{12}\right)^{12*t}}{\left(1+\frac{r}{12}\right)^{12*t}-1}\\\\[/tex]
which to be honest is a big ugly mess of variables. The fractions also make things even more messy. Through trial and error, you can find various ways to help clean up the formula.
Notice how the "r/12" seems to show up a lot. Let's replace that fraction with the variable A.
So we'll make A = r/12
Because of that, the expression [tex]\left(1+\frac{r}{12}\right)^{12*t}[/tex] turns into [tex]\left(1+A\right)^{12*t}[/tex]
After replacing all the "r/12" terms with "A", we have the formula
[tex]M = \frac{P*\left(\frac{r}{12}\right)*\left(1+\frac{r}{12}\right)^{12*t}}{\left(1+\frac{r}{12}\right)^{12*t}-1}\\\\[/tex]
turn into
[tex]M = \frac{P*A*\left(1+A\right)^{12*t}}{\left(1+A\right)^{12*t}-1}\\\\[/tex]
which is a bit simpler in my opinion.
------------------
We could also let
B = (1+A)^(12t)
which would then allow us to go from this
[tex]M = \frac{P*A*\left(1+A\right)^{12*t}}{\left(1+A\right)^{12*t}-1}\\\\[/tex]
to this
[tex]M = \frac{P*A*B}{B-1}\\\\[/tex]
and that's even more simple
---------------------
We're given the following values
P = 75,000 = amount loanedr = 0.023 = annual interest rate in decimal formt = 10 = number of yearsBased on those values, we can say
A = r/12 = 0.023/12 = 0.00191667 approximatelyB = (1+A)^(12*t) = (1+0.00191667)^(12*10) = 1.25832348 approximatelyFrom here, we plug the values of P, A, and B into the simplified version of the formula below.
[tex]M = \frac{P*A*B}{B-1}\\\\M \approx \frac{75000*0.00191667*1.25832348}{1.25832348-1}\\\\M \approx \frac{180.88431483087}{0.25832348}\\\\M \approx 700.22405563\\\\M \approx 700.22\\\\[/tex]
The monthly payment is roughly $700.22

A manufacturer reports that the mean lifetime of its lithium batteries is 1100 hours, but there are customer complaints that the battery life is lower. A consumer advocate group selects 25 of these batteries at random and finds the mean lifetime to be 1080 hours with a standard deviation of 80 hours. The sample data are approximately symmetric and unimodal with no outliers. Check conditions, show how the test statistic is calculated. Test using a 10% significance level. State your conclusion in the context of the problem.
Answers
Answer:
The p-value of the test is 0.1117 > 0.1, which means that there is not significant evidence at the 10% significance level that the battery life is lower than 1100 hours.
Step-by-step explanation:
A manufacturer reports that the mean lifetime of its lithium batteries is 1100 hours, but there are customer complaints that the battery life is lower.
At the null hypothesis, we test that the mean lifetime of the battery is of 1100 hours, that is:
[tex]H_0: \mu = 1100[/tex]
At the alternate, we test that is is lower, that is:
[tex]H_a: \mu < 1100[/tex]
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 value tested at the null hypothesis, s is the standard deviation of the sample and n is the size of the sample.
1100 is tested at the null hypothesis:
This means that [tex]\mu = 1100[/tex]
A consumer advocate group selects 25 of these batteries at random and finds the mean lifetime to be 1080 hours with a standard deviation of 80 hours.
This means that [tex]n = 25, X = 1080, s = 80[/tex]
Test statistic:
[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]
[tex]t = \frac{1080 - 1100}{\frac{80}{\sqrt{25}}}[/tex]
[tex]t = -1.25[/tex]
P-value of the test and decision:
The p-value of the test is the probability of finding a sample mean below 1080, which is found using a left-tailed test for t = -1.25, with 25 - 1 = 24 degrees of freedom.
With the help of a calculator, this p-value is of 0.1117
The p-value of the test is 0.1117 > 0.1, which means that there is not significant evidence at the 10% significance level that the battery life is lower than 1100 hours.

Active ingredient of a pill comprises 45% of the pill mass. If a pill contains 325 mg of active ingredient,
what the total mass of the pill?
Answers
Answer:
Step-by-step explanation:
The idea here is to be able to write and then solve the equation needed for this. In words, this is what you are looking to solve: "The active ingredinet is 45% of the mass of the pill". Putting those words into an equation:
active ingredient = .45 (mass of pill). Since our active ingredient is 35 mg:
325 = .45m and divide by .45:

Circle O is centered on the origin with a diameter of 14 units. Determine if the point
reasoning
(-3,2/10)
is on the circle. Explain your reasoning
Answers
Answer:
Circle centered on origin, (0, 0)
Radius = 7units
To find if the point lies on the circle , check if the distance from the center to the point is 7units.
[tex]distance = \sqrt{(x_{1} -x_{2})^{2} +(y_{1} -y_{2})^{2} } \\(x_{1} ,y_{1} ) =(0, 0)\\(x_{2}, y_{2}) = (-3, 2\sqrt{10} )\\\\distance = \sqrt{(0--3)^2+(0-2\sqrt{10})^2 } = \sqrt{9+40} = \sqrt{49} = 7units[/tex]
Since the distance between the center and the point is 7units. the point lies on the circle.

(p, q) = (-3,2√10)
[tex]D = \sqrt{(x-p)^2 + (y-q)^2} \: \rm units.[/tex]

D) The common ratio;
i) The first term
2. Solve for x and y in the following equations: 2(x+4y) = 1.22+8y
Answers
Answer:
A) 60
B) Common ratio, r, = 2/3
The first term, a, = 13.5
Step-by-step explanation:
A)
The formula for the nth term of a linear sequence is an+b. So we can say:
30=5a+b
75=20a+b
which means
b=30-5a
b=75-20a
30-5a=75-20a
15a=45
a=3
30=5(3)+b
b=30-15=15
So our formula is 3n+15. Sub in 15 for n to find the 15th term: 3(15)+15=45+15=69
B)
The formula for the nth term of an exponential sequence is arⁿ⁻¹, where a is the first term of the sequence and r is the common ratio. Therefore we can say: 9=ar, and 4=ar³, which means a=9/r and a=4/r³
9/r=4/r³
9r³=4r
9r²=4
r=√(4/9)=2/3
9=a(2/3)
a=27/2=13.5

Putting soil is sold in bags that contain 1/2 cubic foot of soil. Estimate how many bags Rylee should buy.
Answers
9514 1404 393
Answer:
11 bags
Step-by-step explanation:
12. As you noted in problem 11, the volume needed to fill the three pots is 5.05 cubic feet. The number of bags needed is ...
(5.05 ft³)/(0.5 ft³/bag) = 10.1 bags
10 bags is not quite enough. Rylee should buy 11 bags of potting soil.
_____
Additional comment
As a practical matter, the difference between what Rylee needs and what is contained in 10 bags is about 1%. It would be very difficult to tell that 0.1 cubic foot is missing if Rylee simply used the contents of 10 bags. If Rylee purchases 11 bags, most (4/5) of the last bag will remain unused.
