Answer:
The slope-intercept form is y=-2x+16.
Answer:
A. 5400-8x
B. $600
Step-by-step explanation:
5400-8x=600
8x=5400-600
x=4800/8=600
Answer:
The sample size 'n' = 384
Step-by-step explanation:
<u>Step(i)</u>:-
Given data the margin of error = 0.05
The margin of error of the estimation of a population proportion is determined by
![M.E = \frac{Z_{\frac{\alpha }{2} }\sqrt{p(1-p} }{\sqrt{n} }](https://tex.z-dn.net/?f=M.E%20%3D%20%5Cfrac%7BZ_%7B%5Cfrac%7B%5Calpha%20%7D%7B2%7D%20%7D%5Csqrt%7Bp%281-p%7D%20%20%7D%7B%5Csqrt%7Bn%7D%20%7D)
<u><em>Step(ii)</em></u>:-
In data not given sample proportion 'p' but
we know that ![\sqrt{p(1-p} \leq \frac{1}{2}](https://tex.z-dn.net/?f=%5Csqrt%7Bp%281-p%7D%20%5Cleq%20%5Cfrac%7B1%7D%7B2%7D)
![0.05 = \frac{1.96 X \frac{1}{2} }{\sqrt{n} }](https://tex.z-dn.net/?f=0.05%20%3D%20%5Cfrac%7B1.96%20X%20%5Cfrac%7B1%7D%7B2%7D%20%7D%7B%5Csqrt%7Bn%7D%20%7D)
cross multiplication, we get
0.05 ×√n = 0.98
![\sqrt{n} = \frac{0.98}{0.05} = 19.6](https://tex.z-dn.net/?f=%5Csqrt%7Bn%7D%20%3D%20%5Cfrac%7B0.98%7D%7B0.05%7D%20%3D%2019.6)
<em>squaring on both sides, we get</em>
<em>n = 384.16≅ 384</em>
<u><em>Final answer</em></u><em>:-</em>
<em>The sample size 'n' = 384</em>
Answer:
A. It is accurate. The phrase can be translated as “three” = 3, “less than” = subtraction, and “a number” = x, so 3-x is the correct expression.
Step-by-step explanation:
Answer:
![Annual\ Earnings = \$53700](https://tex.z-dn.net/?f=Annual%5C%20Earnings%20%3D%20%5C%2453700)
Step-by-step explanation:
Given
(yearly)
(monthly)
![Sales = \$6.75](https://tex.z-dn.net/?f=Sales%20%3D%20%5C%246.75)
Required
Determine the total annual earnings
First, we need to determine the earnings from sales in a year
There are 12 months in a year;
So:
![Total\ Sales = 200 * 12 * \$6.75](https://tex.z-dn.net/?f=Total%5C%20Sales%20%3D%20200%20%2A%2012%20%2A%20%5C%246.75)
![Total\ Sales = \$16200](https://tex.z-dn.net/?f=Total%5C%20Sales%20%3D%20%5C%2416200)
Annual Earnings is then calculated as thus:
![Annual Earnings = \$16200 + \$37500](https://tex.z-dn.net/?f=Annual%20Earnings%20%3D%20%5C%2416200%20%2B%20%5C%2437500)
![Annual\ Earnings = \$53700](https://tex.z-dn.net/?f=Annual%5C%20Earnings%20%3D%20%5C%2453700)
