The percentage searched is 4.2%
If you multiply some value to 1.042 this means that you are adding 4.2 %
See in the expression of formula that appears just the cited figure: "1.042"
Answer:
4
Step-by-step explanation:
Subtract 108 from 124 and get 16 then count up how many tables he did in between 6 and 10 that would be 4 so, 16 divided by 4 is 4 :)
To conduct a hypothesis test for the above situation. We define the null hypothesis and the alternative hypothesis.
The null hypothesis is the claim that the average commute time to downtown is 20 minutes while the alternative hypotheis is a contradiction of the null hypothesis which is that the <span>average commute time to downtown is not 20 minutes</span>.
i.e. H0: μ = 20 and H1: μ ≠ 20.
The z-statistics is given by (sample mean - hypothesized mean) divided by (standard deviation divided by the square root of the sample size).
i.e.
Therefore, <span>The z-statistic is 3.32, so the null hypothesis should be rejected. Because the calculated value of z (3.32) is greater than the table value of z (1.96).
*The table value of z is the z (alpha / 2) of the significant level.</span>
To add and simplify two fractions, we first need to get a common denominator (bottom number).
9/16 + 1/2 --> since 2 goes into 16, we can use 16 for both.
Now since 2×8 = 16, we multiply the top (numerator) by that as well, since they're equal to the same quantity: 1×8 = 8, so we are ready to add our modified fractions: 9/16 + 8/16
Secondly, to add two fractions with a common denominator, we simply add the two numerators, then put them over that common denominator:
9/16 + 8/16 = (9+8)/16 = 17/16
Third step is to simply (or reduce) the fraction into its smallest possible ratio. Here only 1 and 17 are factors of 17, so we cannot reduce it any more. If it were instead, say 18/16, then we could reduce it by 2 to: 9/8
Last step is if the problem asks for a mixed numeral (number), then we would could convert it into: 1 1/16, but usually the improper fraction will do. So our final answer is 17/16.
