Answer:
C. In step 2, Cindy should have multiplied both sides of the equation by 2.
Step-by-step explanation:
I'll go through the equation correctly, and then point out what would have happened.
3 = x/2 - 5
Add 5 to both sides. -5 and 5 cancel out.
8 = x/2
What Cindy should have done here is multiply by 2, not divide by 2. It is important to remember that you do the INVERSE operation to cancel out a number.
What would have happened here is that we have an extra step (though either way we still end up with x being 16.)
Correct Step 2:
Multiply both sides by 2. x/2 and 2x cancel out.
x = 16
Incorrect Step 2:
8/2 = (x/2)/2
4 = x/4
Multiply both sides by 4 (this would be the extra step!).
16 = x
Answer:
I think it is B. ![\frac{2}{1.5}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B1.5%7D)
Step-by-step explanation:
the number on the x-axis is placed at the numerator and the number on the y-axis is placed at the denominator.
the line crosses the point (2,1.5)

Answer:
3.06
Step-by-step explanation:
The correct answer is - 3.06
Reason -
For sample A :
mean,
= 8.05
Standard deviation,
= 1.36
Size,
= 50
For sample B :
mean,
= 7.26
Standard deviation,
= 1.06
Size,
= 38
Now,
-
= 8.05 - 7.26 = 0.79
Standard deviation error, SE = √(
²/
+
²/
) = 0.2580
Now,
Z-statistic = (
-
)/ SE
= 0.79/0.2580
= 3.06
⇒Z-statistic = 3.06
