Answer:
Well 0.5 is the same as 1/2 but I'll try to help.
Step-by-step explanation:
1/9+1/8 is 0.2361. That would honestly be closer to zero but the way that it is worded, it is closer to 1/2 because you are using fractions in the problem. If you were using decimals, I would use 0.5
Answer:
Step-by-step explanation:
Given that n =30, x bar = 375 and sigma = 81
Normal distribution is assumed and population std dev is known
Hence z critical values can be used.
For 95% Z critical=1.96
Margin of error = 
Confidence interval = 375±29
=(346,404)
B) 99% confidence
Margin of error = 2.59*Std error =38
Confidence interval = 375±38
=(337, 413)
C) For 90%
Margin of error = 20
Std error = 20/1.645 = 12.158

Atleast 44 people should be sample size.
Hey!
The first step to solving this problem would be to multiply 469.82 by 0.085.
<em>New Equation :</em>
469.82 × 0.085 = ?
<em>Solution {New Equation Solved} :</em>
469.82 × 0.085 = 39.9347
Ignore the forty seven at the end of the solution. You're only going to need 39.93. Now we'll add 469.82 and 39.93. This is the sales tax plus the regular price. Which will then bring us to our total.
<em>New Equation :</em>
469.82 + 39.93 = ?
<em>Solution {New Equation Solved} :</em>
469.82 + 39.93 = 509.75
<em>So, 469.82 plus 8.5 sales tax is</em> 509.75.
Hope this helps!

The answer is 8.4km/hr
(6+6+6+12+12)÷5=8.4
I don't know how to explain it it's as easy as 2+2 but as hard as explaining how to get 4 from 2+2
Do it do it do it do it do it figure the answer
