If we collect like terms of the first equation, we can simplify to
2x - 8 = 180
If we add 8 to both sides, we get
2x = 188
And that means x = 94
If we substitute this into the second equation, we get
7(94) - 8 = ?
7 x 94 is equal to 658
658 - 8 = 650
I only could find part of the triangle sorry, but u1 is 2 radical 2
A. 4x - y = 8
y = -8 y-int (0,-8)
x = 2. x-imt (2,0)
b. 6x - y = -3
x = -1/2 (-1/2, 0) x int
y = 3 : (0,3) y-intercept
c. x = -5 x-int (-5,0)
y -int (0,25) y = 25
Answer:
The answer is "0.0023 and Choice a"
Step-by-step explanation:
In point a:
The central limit theorem:

In point b:
The chance is lower than 0.05. This means that it is very rare to see the average sample above 251.8 if the argument is valid, that is why the means of the sample is far away from the common claimed and casts doubt on the actual mean.
