Answer:
-2.5 = x
Step-by-step explanation:
-10 = 4x
the equation between 4 and x is multiplication
as our goal is to move the x on its separate side, we should divide each side by 4 to get rid of the bond between the 4 and the x
Therefore,
-10 = 4x
-10/4 = x
Simplify into decimal if needed
-2.5 = x

Answer:
(B) The correct interpretation of this interval is that 90% of the students in the population should have their scores improve by between 72.3 and 91.4 points.
Step-by-step explanation:
Confidence interval is the range the true values fall in under a given <em>confidence level</em>.
Confidence level states the probability that a random chosen sample performs the surveyed characteristic in the range of confidence interval. Thus,
90% confidence interval means that there is 90% probability that the statistic (in this case SAT score improvement) of a member of the population falls in the confidence interval.
Answer:
Step-by-step explanation:
Equation for the linear function has been given as,
y = 26 - 4x
For x = 1,
y = 26 - 4(1)
= 26 - 4
= 22
For x = 2,
y = 26 - 4(2)
= 26 - 8
= 18
For x = 3,
y = 26 - 4(3)
= 26 - 12
= 14
For x = 6,
y = 26 - 4(6)
= 26 - 24
= 2
Therefore, table for the function will be,
x y
1 22
2 18
3 14
6 2
