We have to use the exponent laws to figure this out. When we are multiplying a number with the same bases, we just simply add the exponents. So it would look something like this:
[tex]=11^{8\ +\ -7\ +\ 3}[/tex]
eight plus negative seven equals one, plus three equals four.
So the simplified form will be 11⁴
a = 11

A used car dealership initially prices a car at $12,000. When the car fails to sell, the dealership reduces the prices to $10,500. During a holiday sale, the dealership drops the price of the car an additional 5 percent below the reduced price. To the nearest tenth of a percent, what is the total percent discount from the car's initial price to the holiday sale price?
Answer:
16.9% to the nearest tenth of a percent
Step-by-step explanation:
First, find the FINAL sale price (after the additional holiday 5% reduction).
If we wish to reduce $10,500 by 5%, that means the final price is 95% of the before price.
95% = 95/100 = 0.95
So 95% of $10,500 = 0.95 x 10500 = $9,975
To find the total percent discount, we use the percent change formula:
percent change = (difference between the values ÷ original amount) x 100
= ((12000 - 9975) ÷ 12000) x 100
= 16.875%
So the total percent discount from the car's initial price to the hoiday sale price is 16.9% to the nearest tenth of a percent.

This claim is to be investigated at .01 levels. “Forty percent or more of those persons who retired from an industrial job before the age of 60 would return to work if a suitable job were available. “Seventy-four persons out of the 200 sampled said they would return to work
- State the null hypothesis.
- What is the decision rule?
- Compute the value of the test statistic.
According to the described situation, we have that:
The null hypothesis is [tex]H_0: p < 0.4[/tex]The decision rule is:
z < 2.327: Do not reject the null hypothesis.z > 2.327: Reject the null hypothesis.The value of the test statistic is of z = -0.866.
What is the null hypothesis?The claim is:
"Forty percent or more of those persons who retired from an industrial job before the age of 60 would return to work if a suitable job were available"
At the null hypothesis, we consider that the claim is false, that is, the proportion is of less than 40%, hence:
[tex]H_0: p < 0.4[/tex]
What is the decision rule?We have a right-tailed test, as we are testing if a proportion is less/greater than a value. Since we are working with a proportion, the z-distribution is used.
Using a z-distribution calculator, the critical value for a right-tailed test with a significance level of 0.01 is of z = 2.327, hence, the decision rule is:
z < 2.327: Do not reject the null hypothesis.z > 2.327: Reject the null hypothesis.What is the test statistic?The test statistic is given by:
[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]
In which:
[tex]\overline{p}[/tex] is the sample proportion.p is the proportion tested at the null hypothesis.n is the sample size.In this problem, the parameters are:
[tex]p = 0.4, n = 200, \overline{p} = \frac{74}{200} = 0.37[/tex]
Hence:
[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]
[tex]z = \frac{0.37 - 0.4}{\sqrt{\frac{0.4(0.6)}{200}}}[/tex]
[tex]z = -0.866[/tex]
The value of the test statistic is of z = -0.866.

True or False? When adding two vectors in magnitude-direction form, we add the magnitudes together and add the direction angles together to find our resultant vector.
Answer:
True
Step-by-step explanation:
The resultant is the vector sum of two or more vectors. It is the result of adding two or more vectors together.
Answer:
The answer is true
Step-by-step explanation:
If we add the same two vectors in a different order it will still give the same resultant vector.
The point P = (x, - 2/7) lies on the unit circle shown below. What is the value of x in simplest form?
Answer: [tex]x = \frac{3\sqrt{5}}{7}\\\\[/tex]
Explanation:
The equation of the unit circle is [tex]x^2+y^2 = 1\\\\[/tex]
Plug in y = -2/7 and solve for x
[tex]x^2+y^2 = 1\\\\x^2+\left(-\frac{2}{7}\right) = 1\\\\x^2+\frac{4}{49} = 1\\\\x^2 = 1-\frac{4}{49}\\\\x^2 = \frac{49}{49}-\frac{4}{49}\\\\x^2 = \frac{45}{49}\\\\x = \sqrt{\frac{45}{49}} \ \ \text{ ... x is positive}\\\\x = \frac{\sqrt{45}}{\sqrt{49}}\\\\x = \frac{\sqrt{9*5}}{7}\\\\x = \frac{\sqrt{9}*\sqrt{5}}{7}\\\\x = \frac{3\sqrt{5}}{7}\\\\[/tex]

A small town surveyed 250 adults, 180 of whom were parents, about whether a park should be expanded. The results showed that 150 of the adults who were parents and 40 of the adults who were not parents thought the park should be expanded.
Use this information to complete the two-way table.
Enter your answer by filling in the boxes to complete the table.
Should the park be expanded?
Yes No
Parents
Not parents
Answer:
Yes, the park should be expanded
Explanation:
180 adults said yes.
250 - 180 = 70
70 people thought the park shouldn't be expanded, but there are more people who want the mark to expand.
The perimeter of a rectangular window is 26 feet. The width of the window is 5 feet more than the length. What are the dimensions of the window?
Answer:
length = 4 feet
width = 9 feet
Step-by-step explanation:
Perimeter of a rectangle = 2W + 2L, where W is the width and L is the length
If the perimeter is 26 feet, then: 26 = 2W + 2L
If the width is 5 feet more than the length, then: W = L + 5
Substitute W = L + 5 into 26 = 2W + 2L and solve for L:
26 = 2(L + 5) + 2L
26 = 2L + 10 + 2L
26 = 4L + 10
16 = 4L
L = 4
Now substitute L = 4 into W = L + 5 to find W:
W = 4 + 5 = 9
Therefore, length = 4 feet and width = 9 feet
Answer:
Length = 4 feetWidth = 9 feetStep-by-step explanation:
We know that:
Perimeter of window = 26 feet = 2L + 2WWidth = 5 + LengthSolution:
26 feet = 2L + 2W=> 26 feet = 2L + 2(5 + L)=> 26 feet = 2L + 10 + 2L=> 26 feet = 4L + 10=> 26 - 10 = 4L=> 16 = 4L=> Length = 4 feet=> Width = 5 + Length=> Width = 5 + 4=> Width = 9 feetHence, the length of the window is 4 feet and the width of the window is 9 feet.

Ammonia is a compound consisting of a 1:3 ratio of nitrogen and hydrogen atoms. If a sample contains 1983 hydrogen
atoms, how many total atoms are present?
Answer:
2644 atoms
Step-by-step explanation:
1983/3 = 661
1983 + 661 = 2644 atoms
Answer:
2644 total N and H atoms
Step-by-step explanation:
N/H is 1/3
N/H = 1/3
N/(1983) = 1/3
N = (1983/3)
N = 661 N atoms
1983 + 661 = 2644 total N and H atoms.

Answer:
x < 2.5x > 2.5Step-by-step explanation:
One way to do this is to try a number for x and see if it makes the inequality true. A suitable number here is x=0. This value of x is less than 2.5.
1.For x=0, you have ...
5 > -5 . . . . . true; the solution space is x < 2.5
__
2.For x=0, you have ...
-25 > -5(2.5)
-25 > -12.5 . . . . . false; the solution space is x > 2.5
_____
Alternate solution
1.Subtract 5:
-4x > -10
Divide by -4
x < 2.5
__
2.Divide by -5:
5 < x +2.5
Subtract 2.5
2.5 < x
x > 2.5
