Answer:
Step-by-step explanation:
a. P(Z > 1.12) = 1-N(1.12) = 1-0.8686431=0.1313569
b. <em>P(Z S-2.35)</em> => P(Z <= 2.35) = 0.009386706
(please check interpretation of question b)
c. <em>POSZ s 1.34)</em> => P(0 <= Z <= 1.34) = 0.9098773 - 0.5 = 0.4098773
(please check interpretation of question c)
d. P(-0.8 sz s 2.44) => P(-0.8 <= 2.44) = 0.9926564 - 0.2118554 = 0.780801
(please check interpretation of question d)
The solution of the equation is x = 0 and y = 8.
Given
The system of equation is;
![\rm -5x + 5y = 40\\\\4x + 3y = 24](https://tex.z-dn.net/?f=%5Crm%20-5x%20%2B%205y%20%3D%2040%5C%5C%5C%5C4x%20%2B%203y%20%3D%2024)
<h3>How to find the solution to a system of equations?</h3>
Any system of equations can be solved in different methods. To solve a system of equations in 2 variables, we need at least 2 equations following all the steps given below.
From equation 1
![\rm -5x+5y=40\\\\5y=40+5x\\\\y = \dfrac{40+5x}{5}\\\\y = 8+x](https://tex.z-dn.net/?f=%5Crm%20-5x%2B5y%3D40%5C%5C%5C%5C5y%3D40%2B5x%5C%5C%5C%5Cy%20%3D%20%5Cdfrac%7B40%2B5x%7D%7B5%7D%5C%5C%5C%5Cy%20%3D%208%2Bx)
Substitute the value of y in equation 2
![\rm 4x+3y=24\\\\4x+3(8+x)=24\\\\4x+24+3x=24\\\\7x=24-24\\\\7x=0\\\\x=0](https://tex.z-dn.net/?f=%5Crm%204x%2B3y%3D24%5C%5C%5C%5C4x%2B3%288%2Bx%29%3D24%5C%5C%5C%5C4x%2B24%2B3x%3D24%5C%5C%5C%5C7x%3D24-24%5C%5C%5C%5C7x%3D0%5C%5C%5C%5Cx%3D0)
Substitute x = 0 in the equation 1
![\rm -5x+5y=40\\\\-5(0)+5y=40\\\\5y=40\\\\y=\dfrac{40}{5}\\\\y=8](https://tex.z-dn.net/?f=%5Crm%20-5x%2B5y%3D40%5C%5C%5C%5C-5%280%29%2B5y%3D40%5C%5C%5C%5C5y%3D40%5C%5C%5C%5Cy%3D%5Cdfrac%7B40%7D%7B5%7D%5C%5C%5C%5Cy%3D8)
Hence, the solution of the equation is x = 0 and y = 8.
