M_6 is (2x – 5)º and m_8 is (x + 5)º.

Mathematics
1 answer:
HACTEHA [7]2 years ago
4 0

m_6 + m_8 = 180º because they form a straight line.

So, (2x-5) + (x+5) = 180

    3x = 180

      x = 60

So, m_115º    (2•60 - 5 = 115)

Also, because the two lines are parallel m_6 = m_3 by alternate interior angles.

So, m_3 = 115º

5 squirrels were found to have an average weight of 8.9 ounces with a sample standard deviation is 0.9. Find the 95% confidence
stira [4]

Answer: ( 8.11 , 9.69)

the 95% confidence interval of the true mean weight

= ( 8.11 , 9.69)

Step-by-step explanation:

Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.

The confidence interval of a statistical data can be written as.

x+/-zr/√n

Given that;

Mean x = 8.9

Standard deviation r = 0.9

Number of samples n = 5

Confidence interval = 95%

z(at 95% confidence) = 1.96

Substituting the values we have;

8.9+/-1.96(0.9/√5)

8.9+/-1.96(0.4025)

8.9+/- 0.79

= ( 8.11 , 9.69)

Therefore at 95% confidence interval (a,b) = ( 8.11 , 9.69)

What are the steps for this problem? -10-8n=n-(8n+8)
Elden [556K]

Answer:

n =  - 2

Step-by-step explanation:

- 10 - 8n = n - (8n + 8)

First, you should distribute the -1 on the right.

- 10 - 8n = n - 8n - 8

Next, add 8n to both sides. This should cancel out the 8n.

- 10 = n - 8

Now, add 8 to both sides. This will get n by itself.

- 2 = n

Your answer is n = -2.

What is y > 2x - 4 and 6x +3y < 9​
fgiga [73]

you can make a table of values using any intergers and as many as you need in this case I chose 0,1,2 then you replace them in your actual equation and find the values of y.finally plot.

after plotting the points you shade the unwanted region(the sign will direct you) in this case the wanted region is y>.so you shade the less than area.

for the second one you make the equation simpler

6x+3y<9

3y<-6x+9

and also make a table of values,replace were there's x and plot

I hope this helps!
