Luden [163]2 years ago

Answer:  y=7,x=3

Steps:

y = 2x + 1

3x + y = 16

Substitute y = 2x + 1

3x + 2x + 1 = 16

Simplify

5x+1=16

Isolate x for 5x + 1 = 16: x = 3

For y = 2x + 1

Substitute x = 3

y = 2 · 3 + 1

Simplify

y = 7

The solutions to the system of equations are:

y = 7, x = 3

Hope This Helps!

Zepler [3.9K]

Answer: 83

Step-by-step explanation:

The confidence interval for population mean is given by :-

\overline{x}\pm E

Given : The student obtained the following​ 95% confidence interval​ (in grams) for the population​ mean, (862,1028).

Here,

Lower limit of the confidence interval : \overline{x}-E=862  (1)

Upper limit of the confidence interval : \overline{x}+E=1028   (2)

Subtracting (1) from (2) , we get

2E=166\\\\\Rightarrow\ E=\dfrac{166}{2}=83

Hence, the margin of​ error = 83
