Round 20.86 to the nearest tenth

20
20.8
20.86
20.9

Answers

Answer:

20.9 is the answer because To round 20.86 to the nearest tenth consider the hundredths’ value of 20.86, which is 6 and equal or more than 5. Therefore, the tenths value of 20.86 increases by 1 to 9. 20.86 rounded to the nearest tenth = 20.9

Simplify 0.05 +1.02x

Answers

0.005x + 1.02x

= ( 0.05 + 1.02 )x

= 1.07x

Hope this helps!

~LENA~

I'm assuming the 0.05 is supposed to have an x after it but you can combine like terms.

0.05x + 1.02x =x(0.05+1.02)=1.07x

Weights of men: 90% confidence; n = 14, x=161.5 lb, s =13.7 lb

Answers

Answer:

The 90% for the average weights of men is between 137.24 lb and 185.76 lb.

Step-by-step explanation:

We have the standard deviation for the sample, so we use the t-distribution to solve this question.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 14 - 1 = 14

90% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 14 degrees of freedom(y-axis) and a confidence level of 1 - (1 - 0.9)/(2) = 0.95. So we have T = 1.7709

The margin of error is:

M = T*s = 1.7709*13.7 = 24.26

In which s is the standard deviation of the sample.

The lower end of the interval is the sample mean subtracted by M. So it is 161.5 - 24.26 = 137.24 lb

The upper end of the interval is the sample mean added to M. So it is 161.5 + 24.26 = 185.76 lb

The 90% for the average weights of men is between 137.24 lb and 185.76 lb.
