Answer 1
8x + 3y = 45 * -2 Negative
2x + 3y = 27 * 8 Positive

-16x - 6y = 90
16x + 24y = 216

24y is equal to 216
y is equal to 216/or 24
y is equal to 9

Which means:
8 + 3y = 216
y = 216/24
y = 9


8x + 3y = 45
8x + 3 (Which is 9) = 45

So the Answer is:
8x=45 - 27
8x= 18
X=18/8
X= 2.25



Hope this helps you

Answers

Answer:

B. h=8

Step-by-step explanation:

The answer is B. h=8. I know because I solved to get h by itself. First, I set up the problem.

7.2h=57.6

Then, I divided each side by 7.2, so I could get h by itself.

h=8

You can check to make sure this is correct by plugging in the value we got for h into the equation.

7.2(8)=57.6

In conclusion, the answer is B. h=8

Which is the best example of an explicit statement from Thoughts and Sentiments that shows Cugoano's beliefs about slavery?
A. “However, notwithstanding all that has been done and written against it, that brutish barbarity, and unparalelled injustice, is still carried on to a very great extent in the colonies, and with an avidity as insidious, cruel and oppressive as ever.”
B. “However, it cannot but be very discouraging to a man of my complexion in such an attempt as this, to meet with the evil aspersions of some men, who say, ‘That an African is not entitled to any competent degree of knowledge, or capable of imbibing any sentiments of probity; and that nature designed him for some inferior link in the chain, fitted only to be a slave.’”
C. “By some of such complexion, as whether black or white it matters not, I was early snatched away from my native country, with about eighteen or twenty more boys and girls, as we were playing in a field.”
D. “But the supporters and favourers of slavery make other things a pretence and an excuse in their own defence; such as, that they find that it was admitted under the Divine institution by Moses, as well as the long continued practice of different nations for ages; and that the Africans are peculiarly marked out by some signal prediction in nature and complexion for that purpose.”

Answers

Answer:

A. “However, notwithstanding all that has been done and written against it, that brutish barbarity, and unparalelled injustice, is still carried on to a very great extent in the colonies, and with an avidity as insidious, cruel and oppressive as ever.”

Explanation:

Ottobah Cugoano's "Thoughts and Sentiments on the Evil of Slavery" provides a personal take on the issue of slavery and how evil of a practice it is for African Americans. At the same time, he also asserted that slaves had the right to rebel against their masters for the treatment they were put under.

One explicit statement that reveals the author's beliefs about the slavery system is "However, notwithstanding all that has been done and written against it, that brutish barbarity, and unparalelled injustice, is still carried on to a very great extent in the colonies, and with an avidity as insidious, cruel and oppressive as ever." Through these lines, Cugoano labels slavery as "brutish barbarity, and an unparallelled injustice ... insidious, cruel and oppressive..."

Thus, the correct answer is option A.

According to the AAA Foundation for Traffic Safety's American Driving Survey, U.S. drivers spend.

on average, 51 minutes behind the wheel each day. A researcher believes this is an overstatement.

To investigate, a random sample of 75 drivers were selected. The study revealed that the mean

time behind the wheel for the sample of 75 drivers was 46.4 minutes with a standard deviation of

18.8 minutes. Is there convincing evidence that the mean time behind the wheel for all U.S. drivers

is less than 51 minutes? Use a = 0.01.

Answers

Answer:

The pvalue of the test is 0.017 > 0.01, which means that there is not convincing evidence that the mean time behind the whell for all U.S drivers is less than 51 minutes.

Step-by-step explanation:

U.S. drivers spend on average, 51 minutes behind the wheel each day.

This means that at the null hypothesis we test that:

[tex]H_{0}: \mu = 51[/tex]

Is there convincing evidence that the mean time behind the wheel for all U.S. drivers is less than 51 minutes?

This means that the alternate hypothesis is:

[tex]H_{a}: \mu < 51[/tex]

The test statistic is:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.

51 is tested at the null hypothesis:

This means that [tex]\mu = 51[/tex]

The study revealed that the mean time behind the wheel for the sample of 75 drivers was 46.4 minutes with a standard deviation of 18.8 minutes.

This means that [tex]n = 75, X = 46.4, \sigma = 18.8[/tex]

Value of the test-statistic:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

[tex]z = \frac{46.4 - 51}{\frac{18.8}{\sqrt{75}}}[/tex]

[tex]z = -2.12[/tex]

Pvalue of the test:

The pvalue of the test is the probability of finding a sample mean less than 46.4, which is the pvalue of z when X = 46.4.

Looking at the z-table, z = -2.12 has a pvalue of 0.017.

Decision:

The pvalue of the test is 0.017 > 0.01, which means that there is not convincing evidence that the mean time behind the whell for all U.S drivers is less than 51 minutes.

No, there isn't convincing evidence that the mean time behind the wheel for all U.S. drivers is less than 51 minutes.

Given the following data:

Mean = 51.Number of drivers = 75 drivers.Sample mean (mean time) = 46.4 minutes.Standard deviation = 18.8 minutes.

What is a null hypothesis?

A null hypothesis ([tex]H_0[/tex]) can be defined the opposite of an alternate hypothesis ([tex]H_a[/tex]) and it asserts that two (2) possibilities are the same.

For the null hypothesis, we would test that:

[tex]H_o : \mu =51[/tex]

For the alternate hypothesis, we would test that:

[tex]H_a : \mu < 51[/tex]

The test statistics would be calculated with this formula:

[tex]Z=\frac{x\;-\;u}{\frac{\delta}{\sqrt{n} } }[/tex]

Where:

x is the sample mean.u is the mean.[tex]\delta[/tex] is the standard deviation.n is the number of drivers.

Substituting the given parameters into the formula, we have;

[tex]Z=\frac{46.4\;-\;51}{\frac{18.8}{\sqrt{75} } }\\\\Z=\frac{-4.6}{\frac{18.8}{8.6603} }\\\\Z=\frac{-4.6}{2.1708 }[/tex]

Z = -2.12.

What is a p-value?

In Statistics, a p-value also known as the probability value is the probability which occurs when the null hypothesis ([tex]H_0[/tex]) is true of obtaining a sample mean that is at least as unlikely as what is observed by a researcher or scientist.

From the z-table, a z-score of -2.12 corresponds to or has a p-value of 0.017. Therefore, the p-value for this test is 0.017 > 0.01.

In conclusion, there isn't convincing evidence that the mean time behind the wheel for all U.S. drivers is less than 51 minutes.

What is the approximate distance between Chaplain and Asherville?
OA. 30.9 miles
OB.
14.7 miles
O c.
29.8 miles
OD.
16.4 miles

Answers

Answer:

B

Step-by-step explanation:

Remark

I'm hesitant to get an exact answer. You could do that with the cos law for distance. To get an approximate answer you could use the Pythagorean Theorem.

I'll try the cos law first.

Formula

c^2 = a^2 + b^2 - 2abcos(C)

Givens

c = 24

a = 18

b = ?

Solution

24^2 = 18^2 + b^2 - 2*18*b*cos(94)

576 = 324 + b^2 - 36*b*(-0.0698)

0 = 324 - 576 + b^2 + 2.511b

0 = b^2 + 2.511 - 252

Using the quadratic formula, the roots are

b1 = 14.66

b2 = - 17.11

The second one has no meaning in the real world.

Answer

the distance is 14.66 miles from Chaplin to Asherville

Note: using the Pythagorean theorem gives 15.87 which I would count as a good approximation.

Which expressions are equivalent to 6 + 12x?

Answers

Answer:

Expressions A, C, D are equivalent

Step-by-step explanation:

Equivalent expressions:

Two expressions are equivalent if they give the same result. So

Option A:

3(2 + 4x)  =3*2 + 3*4x = 6 + 12x

So equivalent

Option B:

3(2 + 6x) + 2x = 3*2 + 3*6x + 2x = 6 + 18x + 2x = 6x + 20. So not equivalent

Option C:

5(1+2x) + 1 + 2x = 5*1 + 5*2x + 1 + 2x = 5 + 10x + 1 + 2x = 6 + 12x.

Equal, so equivalent

Option D:

7*(1+2x) - 2x - 1 = 7*1 + 7*2x - 2x - 1 = 7 + 14x - 2x - 1 = 6 + 12x

Equal, so equivalent.

Option E:

7*(1+2x) + 2x - 1 = 7*1 + 7*2x - 2x - 1 = 7 + 14x + 2x - 1 = 6 + 16x

Different, so not equivalent.

Answers

Answer:

b = 3.5 cm

Step-by-step explanation:

Given that,

The area of a rectangle, A = 14. sq cm

The length of one side, l = 4 cm

We need to find the length of another side. The formula for the area of a rectangle is given by :

A = lb

So,

[tex]14=4b\\\\b=\dfrac{14}{4}\\\\b=3.5\ cm[/tex]

So, the length of the other side is equal to 3.5 cm.

Answers

Answer:

10

Step-by-step explanation:

Can't do that. I have to write some sort of explanation or the mods have a fit.

Side opposite = 5 √3

Sin(60) = √3 /2

Hypotenuse = x

Sin(60) = √3/2 = 5√3 / x

√3/2 = 5√3 / x                  Multiply both sides by x

x √3/2 = 5√3                    Divide both sides by √3

x/2 = 5

x = 10

The hypotenuse is 10 units long.
