Answer:

a=1

Step-by-step explanation:

a+3=2a+2

Take away 3 from both sides

a=2a-1

Take away 2a from both sides

-a=-1

Multiply by -1

a=1

a + 3 = 2a + 2

move 2a to the other side

sign changes from +2a to -2a

a-2a+3= 2a-2a + 2

a-2a+3=2

-a+3=2

move 3 to the other side

-a+3-3= 2-3

-a= 2-3

-a= -1

mutiply both sides by -1 to get +a

(-1)(-a)=(-1)(-1)

Answer:

a= 1

The right answer for the question that is being asked and shown above is that: 

This can be answered using the Pythagorean Theorem.
h2 = a2 + b2
h = square root (8^2 + 5^2)
h = <span>square root (64 + 25)
h = </span><span>square root (89) in
h = 9.4 in

So the correct answer is 9.4 in given the dimension 5 inches and 8 inches.</span>

In a recent study of 42 eighth graders, the mean number of hours per week that they watched television was 19.6. Assume the popu
olya-2409 [2.1K]

Answer:

19.6-2.42\frac{5.8}{\sqrt{42}}=17.43    

19.6+2.42\frac{5.8}{\sqrt{42}}=21.77    

And the best option for this case would be:

a. (17.5, 21.7)

Step-by-step explanation:

Information given

\bar X= 19.6 represent the sample mean

\mu population mean

\sigma= 5.8 represent the population deviation

n=42 represent the sample size  

Confidence interval

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

\bar X \pm t_{\alpha/2}\frac{s}{\sqrt{n}}   (1)

The degrees of freedom, given by:

df=n-1=42-1=41

Since the Confidence is 0.98 or 98%, the significance would be \alpha=0.02 and \alpha/2 =0.1, and the critical value would be t_{\alpha/2}=2.42

Replacing we got:

19.6-2.42\frac{5.8}{\sqrt{42}}=17.43    

19.6+2.42\frac{5.8}{\sqrt{42}}=21.77    

And the best option for this case would be:

a. (17.5, 21.7)
