which of the following is an equation of a line parallel to the equation <img src="https://tex.z-dn.net/?f=y%3D%5Cfrac%7B1%7D%7B
kotykmax [81]

Answer:

Any equation of a line having a slope of 1/2.

Step-by-step explanation:

It appears that the question gives answer choices and this problem could have many solutions, but parallel lines have equal slopes. The slope of this line is 1/2 since it is in y=mx+b form where m is the slope. So a few examples of equations of lines parallel to the given equation would be y = 1/2x - 5 or y = 1/2x + 10 etc.

Find and interpret a 95% confidence interval to estimate the average number of bolts per box for all boxes in the population. Ro

Complete Question

The complete question is shown on the first uploaded image

Answer:

The 95% confidence interval is  49.85    < \mu < 54.15

This means that there is 95% chance that the true population mean is within this interval

Step-by-step explanation:

From the question we are told that

    The  sample size is n = 30  

    The sample mean is  \= x  =  52

    The population standard deviation is  \sigma =  6

Given that the confidence level is 95% then the level of confidence is evaluate as

             \alpha  =  100 -  95

            \alpha  =  5\%

            \alpha  =  0.05

Next we obtain the critical value of  \frac{\alpha }{2} from the normal distribution table , the values 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} }

substituting values

            E =  1.96  *  \frac{ 6 }{\sqrt{30} }

           E =  2.147

The  95% confidence interval is mathematically represented as

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

substituting values

         52   - 2.147   < \mu <  52   +   2.147

         49.85    < \mu < 54.15

Natalija [7]

Answer:I beleive the answer is c-3600

Step-by-step explanation:

90$ a month for 48 months=4320

Plus the interest rate of 8.33  so 4320x0.833=3598.56

Then you have to round up from 3598.56 to the nearest 100 dollars, so it would be 3600.

G(x)= √x+3 help plsss
const2013 [10]

Answer:

All real values of x such that x ≥-3

Step-by-step explanation:

g(x) = sqrt(x+3)

A sqrt must be greater than or equal to zero

sqrt (x+3) ≥ 0

Square each side

x+3≥ 0

Subtract 3 from each side

x ≥-3

The restrictions on x are x ≥-3

That means the domain is x ≥-3

All real values of x such that x ≥-3
