Answer:
Quincy's claim is correct.
Step-by-step explanation:
Margin of error of a confidence interval:
The margin of error of a confidence interval decreases is the sample size increases, that is, if the sample size increases, the width of the interval decreases.
In this question:
Sample size of increases to 30 from 24, which means that the width of the interval will decrease.
Quincy's claim is correct.
Answer:
ofc! :D
Step-by-step explanation:
i- x represents the input
ii- y represents the output
iii- yes, the input (x) is 4 times greater than the output (y)
b just plot them like normal on a coordinate grid :D
Answer:
Step-by-step explanation:
Given the equation:
Begin by subtracting 10 from both sides of the equation:
Then, subtract 2 from both sides of the equation to find the value of :
-
You can check your answer by substituting the x-value into the initial equation:
Since both sides of the equation are equal, our solution is correct.
If they don’t give you an area or what x is , your anwser is 7x^2-4x
the formula for area is base times height
the height is x and the width is 7x-4
(7x-4)*x=7x^2-4
