Cost of 192 tile at $0.80 = 192 x .80 = $153.60
Change due from $200.00 =$200 - $153.60= $46.40
<span>(Y+2) at y=-4
First: You will plug in your y
Your equation should look like: -4+2
Next: You will take 2 and subtract the 4
You will get: -2 as your answer

Answer: ![(24.28,\ 27.72)](https://tex.z-dn.net/?f=%2824.28%2C%5C%2027.72%29)
Step-by-step explanation:
Given : Sample size : ![n=50](https://tex.z-dn.net/?f=n%3D50)
Sample mean : ![\overline{x}=26](https://tex.z-dn.net/?f=%5Coverline%7Bx%7D%3D26)
Standard deviation : ![\sigma =6.2](https://tex.z-dn.net/?f=%5Csigma%20%3D6.2)
Significance level : ![\alpha=1-0.95=0.05](https://tex.z-dn.net/?f=%5Calpha%3D1-0.95%3D0.05)
Critical value : ![z_{\alpha/2}=1.96](https://tex.z-dn.net/?f=z_%7B%5Calpha%2F2%7D%3D1.96)
Formula to find the confidence interval for population mean :-
![\overline{x}\pm z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}\\\\=26\pm(1.96)\dfrac{6.2}{\sqrt{50}}\\\\\approx26\pm1.72\\\\=(26-1.72,\ 26+1.72)\\\\=(24.28,\ 27.72)](https://tex.z-dn.net/?f=%5Coverline%7Bx%7D%5Cpm%20z_%7B%5Calpha%2F2%7D%5Cdfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D%5C%5C%5C%5C%3D26%5Cpm%281.96%29%5Cdfrac%7B6.2%7D%7B%5Csqrt%7B50%7D%7D%5C%5C%5C%5C%5Capprox26%5Cpm1.72%5C%5C%5C%5C%3D%2826-1.72%2C%5C%2026%2B1.72%29%5C%5C%5C%5C%3D%2824.28%2C%5C%2027.72%29)
Hence, a 95% confidence interval for the population mean = ![(24.28,\ 27.72)](https://tex.z-dn.net/?f=%2824.28%2C%5C%2027.72%29)
Answer:
x = 19
Step-by-step explanation:
Solve for x:
3 x + 43 = 100
Subtract 43 from both sides:
3 x + (43 - 43) = 100 - 43
43 - 43 = 0:
3 x = 100 - 43
100 - 43 = 57:
3 x = 57
Divide both sides of 3 x = 57 by 3:
(3 x)/3 = 57/3
3/3 = 1:
x = 57/3
The gcd of 57 and 3 is 3, so 57/3 = (3×19)/(3×1) = 3/3×19 = 19:
Answer: x = 19
Answer:
x=25
Step-by-step explanation:
43=2x-7 (since the midpoint separate a line into two equal halves)
43+7=2x
50/2=x
25=x
