atroni [7]
Since the line is vertical, its slope is "undefined."  This slope has no numerical value.

The point-slope form is y = mx + b.  In this particular problem, the slope, m, is undefined, and there is no y-intercept (the line never crosses the y-axis).

Jaime biked 5 1/4 miles on Monday, 6 7/8 miles on Tuesday, and 8 1/2 miles
adelina 88 [10]
10 1/8 miles would be the answer.

This is because every day he increases by 1 5/8 of a mile.  So if the pattern continues he will bike 10 1/8 miles.

Hope that helps!!

Automobile mechanics conduct diagnostic tests on 150 randomly selected new cars of particular make and model to determine the ex
Archy [21]

Answer:

\mathbf{Margin\;  of\;  error} =  .0942816

Step-by-step explanation:

Given

Sample size n = 150

Sample proportion {\widehat{(p)} = \frac{42}{150} = 0.28

Confidence interval = \frac{99}{100} = .99

Margin\;  of\;  error = z_{\frac{\alpha }{2}}\sqrt{\frac{{\widehat{(p)}}{(1 - \widehat{p})}}{n}}

\alpha = 1 - confidence interval = 1 - 0.99 = .01

margin\;  of\;  error = z_{\frac{.01 }{2}}\sqrt{\frac{(.28) (1 - 0.28)}{150}    

For 99\% confidence interval

        ( Z = 2.576 )

margin\;  of\;  error = z_{.005 }}\sqrt{\frac{(.28) (1 - 0.28)}{150}                  

margin\;  of\;  error = 2.576\times\sqrt{\frac{(.28) (1 - 0.28)}{150}

                           =  .0942816

Solve the following system of equation by using the method of substitution. x + 2y = -1 and 2x – 3y =12
Sergio039 [100]

Answer:

x = 3

y = -2

Step-by-step explanation:

x + 2y = -1

2x – 3y =12

Using substitution means that in one equation you solve for a variable. In this case, the first equation would be easier to solve for x since there are no coefficients.

x = -2y - 1

Now, we plug in the value of x into the second equation, and solve for y.

2 (-2y - 1) - 3y = 12

-4y - 2 - 3y = 12

-7y - 2 = 12

-7y = 14

y = -2

Since we have a numerical value of y, we can use it to solve for x by plugging it into one of the original equations.

x + 2(-2) = -1

x - 4 = - 1

x = 3

If you'd like to check the answer, plug in both values you got to the original equations!

I hope this helps!
