<span>D) Greater than 8 because you are multiplying by a number greater than 1.
8 * 2 1/3 = 8 * 7/3 = 56/3 = 18.67
& we know, 18.67 > 8
Hope this helps!</span>
The value of n in given proportion is 16
<u><em>Solution:</em></u>
We have to find the value of "n" in the proportion
<em><u>Given proportion is:</u></em>
<em><u></u></em>
<em><u></u></em>
We can solve the above proportion by cross-multiplying
Multiply the numerator of the left-hand fraction by the denominator of the right-hand fraction
Multiply the numerator of the right-hand fraction by the denominator of the left-hand fraction
Set the two products equal to each other
Solve for the variable
![->\frac{n}{28} = \frac{4}{7}](https://tex.z-dn.net/?f=-%3E%5Cfrac%7Bn%7D%7B28%7D%20%3D%20%5Cfrac%7B4%7D%7B7%7D)
![-> 7 * n = 4 * 28](https://tex.z-dn.net/?f=-%3E%207%20%2A%20%20n%20%3D%204%20%2A%2028)
![-> n = \frac{4 * 28}{7}](https://tex.z-dn.net/?f=-%3E%20n%20%3D%20%5Cfrac%7B4%20%2A%2028%7D%7B7%7D)
![-> n = 4 * 4 = 16](https://tex.z-dn.net/?f=-%3E%20n%20%3D%204%20%2A%204%20%3D%2016)
Thus the value of n in given proportion is 16
Answer:
8
Step-by-step explanation:
3x is a varable and -1 is an integer
Answer:
![E(\bar{x}) = 28520](https://tex.z-dn.net/?f=E%28%5Cbar%7Bx%7D%29%20%3D%2028520)
Standard error of mean = 689
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = $28,520
Standard Deviation, σ = $5600
Mean of sampling distribution =
![E(\bar{x}) = \mu = 28520](https://tex.z-dn.net/?f=E%28%5Cbar%7Bx%7D%29%20%3D%20%5Cmu%20%3D%2028520)
As per Central Limit Theorem, if the sample size is large enough, then the sampling distribution of the sample means follow approximately a normal distribution.
Sample size, n = 66
Since the sample size is large, we can use normal distribution for approximation.
Standard error of mean =
![\displaystyle\frac{\sigma}{\sqrt{n}} = \frac{5600}{\sqrt{66}} = 689.31 \approx 689](https://tex.z-dn.net/?f=%5Cdisplaystyle%5Cfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D%20%3D%20%5Cfrac%7B5600%7D%7B%5Csqrt%7B66%7D%7D%20%3D%20689.31%20%5Capprox%20689)
Answer:
a) $49.48
b) $220921.91
Step-by-step explanation:
(a) 4 yd @ $12.37 per yd = 4 x $12.37 = $49.48
(b) 271 yd @ 815.21 per yd = 271 x $815.21 = $220921.91
(c) 20% yd @ $4.95 per yd : Here the nunber of yards are missing. Hence could not be answer . However if number of yards is x . The answer would be
20% of 4.95x
(20%=0.20)
0.20 × 4.95x
