What is the equation of the line that passes through (-5,6) and has an undefined slope?

lianna [129]

Hello from MrBillDoesMath!

Answer: x = -5

Discussion:

The line has an undefined slope. This implies the line is vertical and its equation is like "x = a" for some constant "a", We are told the line passes through (-5,6) so the first coordinate, -5, is the "a" value we need.

Thank you,

MrB

if you take 11-3g= 8

making g ____ times 3= 8

g= 2.5

(71+g)=8

Travel time data is collected on an arterial. With 30 runs, an average travel time of 152 seconds is computed over the 2.0 miles

o-na [289]

Answer:

The 95% confidence bounds is $145.80 < \mu < 158.19$

It was not necessary to make any assumption about the shape of the travel time distribution

Step-by-step explanation:

From the question we are told that

The sample size is n = 30

The sample mean is $\=x = 152$

The standard deviation is $\sigma = 17.3 \ second$

From the question we are told the confidence level is 95% , hence the level of significance is

$\alpha = (100 - 95 ) \%$

=> $\alpha = 0.05$

Generally from the normal distribution table the critical value of $\frac{\alpha }{2}$ is

$Z_{\frac{\alpha }{2} } = 1.96$

Generally the margin of error is mathematically represented as

$E = Z_{\frac{\alpha }{2} } * \frac{\sigma }{\sqrt{n} }$

=> $E = 1.96 * \frac{17.3 }{\sqrt{30} }$

=> $E = 6.19$

Generally 95% confidence bounds is mathematically represented as

$\= x -E < \mu < \=x +E$

=> $152 -6.19 < \mu < 152 -6.19$

=> $145.80 < \mu < 158.19$

This 95% confidence bounds show that there is 95% confidence that the true mean lies within this bound hence there is it was not necessary to make any assumption about the shape of the travel time distribution
