X+y=4 and 2x+3y=2 then find x and y​
Sladkaya [172]

Answer:

x=10, y=-6

Step-by-step explanation:

1) express x from the first equation x+y=4 x=4-y

2) It is the system of equations, so both equations are simultaneous.

you can replace x to 4-y in the second one

2 *(4-y) +3y=2

8-2y+3y= 2

y=-6

x= 4-y=4-(-6)=10

The answer is x=10, y=-6

larisa86 [58]

Answer:  0.0432

Step-by-step explanation:

Formula of Margin of Error :-

E=z_{\alpha/2}\sqrt{\dfrac{p(1-p)}{n}}

Given : Sample size : n= 400

The proportion of individuals use public transportation.=\dfrac{65}{330}\approx0.20

Level of confidence = 0.95

Significance level : \alpha=1-0.95=0.05

Critical value : z_{\alpha/2}=1.96

Substitute the values in the given formula , we get

E=(1.96)\sqrt{\dfrac{0.2(1-0.2)}{330}}\\\\\Rightarrow\ E=0.043157779593\approx0.0432

Hence, the margin of error for the confidence interval for the population proportion with a 95% confidence level. = 0.0432
