Answer:

Problem 1: \frac{2x-3}{5}=x+6 gives x=-11

Problem 2: 2x-\frac{3}{5}=x+6 gives x=33/5

Step-by-step explanation:

I will do it both ways:

Problem 1:

\frac{2x-3}{5}=x+6

I don't like the fraction so I'm going to clear by multiplying both sides by 5:

2x-3=5(x+6)

Distribute:

2x-3=5x+30

Subtract 2x on both sides:

-3=3x+30

Subtract 30 on both sides:

-33=3x

Divide both sides by 3:

-11=x

Problem 2:

2x-\frac{3}{5}=x+6

Clear the fraction by multiplying both sides by 5:

5(2x-\frac{3}{5})=5(x+6)

Distribute:

10x-3=5x+30

Subtract 5x on both sides:

5x-3=30

Add 3 on both sides:

5x=33

Divide both sides by 5:

x=\frac{33}{5}

For this case we must solve the following equation:

\frac {2x-3} {5} = x + 6

Multiplying by 5 on both sides we have:

2x-3 = 5 (x + 6)\\2x-3 = 5x + 30

We add 3 to both sides of the equation:

2x = 5x + 30 + 3\\2x = 5x + 33

Subtracting 5x on both sides:

2x-5x = 33\\-3x = 33

Dividing between -3 on both sides:

x = \frac {33} {- 3}\\x = -11

Answer:

-11

The percentage of body fat of a random sample of 36 men aged 20 to 29 found a sample mean of 14.42. Find a 95% confidence interv
Rina8888 [55]

Answer:

14.42-1.96\frac{6.95}{\sqrt{36}}=12.150    

14.42+ 1.96\frac{6.95}{\sqrt{36}}=16.690    

So on this case the 95% confidence interval would be given by (12.150;16.690)    

Step-by-step explanation:

Previous concepts

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".

The margin of error is the range of values below and above the sample statistic in a confidence interval.

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

\bar X=14.42 represent the sample mean

\mu population mean (variable of interest)

\sigma=6.95 represent the population standard deviation

n=36 represent the sample size  

Solution to the problem

The confidence interval for the mean is given by the following formula:

\bar X \pm z_{\alpha/2}\frac{\sigma}{\sqrt{n}}   (1)

Since the Confidence is 0.95 or 95%, the value of \alpha=0.05 and \alpha/2 =0.025, and we can use excel, a calculator or a table to find the critical value. The excel command would be: "=-NORM.INV(0.025,0,1)".And we see that z_{\alpha/2}=1.96

Now we have everything in order to replace into formula (1):

14.42-1.96\frac{6.95}{\sqrt{36}}=12.150    

14.42+ 1.96\frac{6.95}{\sqrt{36}}=16.690    

So on this case the 95% confidence interval would be given by (12.150;16.690)

The domain is all values x can be. There are no restrictions on x. it can be any real number (-∞ , ∞)

The range is all values y can be. There are noi restrictions on y either because the function is odd. y is </span><span>(-∞ , ∞)

The best answer is D.
