Hello!
4/5 = (4 + 8)/x
4x = 5(12) = 60
x = 60/4 = 15
I hope this helps!
<em>The given equation is: E=17/20 D , where E=amount of Euros and D= amount of U.S dollar.
</em>
<em>
</em>
<em>Now for 1 U.S dollar, we need to plug D=1 into the above equation. So, we will get.........
</em>
<em>
E=17/20(1)</em>
<em>E=1/20=0.85</em>
<em>0.85 Euros have the same amount as 1 U.S dollar.

Answer: 12
The factors of 60 are: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
The factors of 72 are: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
The factors of 120 are: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
Then the greatest common factor is 12
Answer:
Step-by-step explanation:
From the given information:
We can compute the null hypothesis & the alternative hypothesis as:


The degree of freedom = n - 1
The degree of freedom = 5 - 1
The degree of freedom = 4
At the level of significance of 0.05 and degree of freedom 4,
the rejection region = 9.488
However, we can compute the chi-square X² goodness of fit test as:
months frequency (p) observed O Expected E Chi-square 
Dec 0.2 16 16
Jan 0.250 11 20
Feb 0.200 16 16
Mar 0.200 18 16 
Apr 0.150 19 12 
Total 1.000 80 80 8.3833
∴
The test statistics X² = 8.3833
Thus; we fail to reject the
since test statistics X² doesn't fall in the rejection region.
Therefore; there is sufficient evidence to conclude that the distribution of snowfalls in her hometown is not similar to the claimed percentage.
