I will one only and you do the rest.
Let x = -2
Plug into given function.
f(-2) = 2 - 5(-2)
f(-2) = 2 + 10
f(-2) = 12
So, when x = -2, f(x) = 12.
Table:
x............ f(x)
-2 12
-1
0
1
2
Find the rest the same way.
Answer:
19 and 23/55
Step-by-step explanation:
Divide using long division. The whole number portion will be the number of times the denominator of the original fraction divides evenly into the numerator of the original fraction, and the fraction portion of the mixed number will be the remainder of the original fraction division over the denominator of the original fraction.
Answer:
y = 3x + 4
Step-by-step explanation:
y = mx + b
b = y-intercept so:
b = 4
Since 4 is the y-intercept that means (0, 4).
To find slope:
m=(y2-y1)/(x2-x1)
m=(4 - 10)/(0 - 2)
m= (-6)/(-2)
m= 3
Slope-intercept:
y - y1 = m(x - x1)
y - 10 = 3(x - 2)
y - 10 = 3x - 6
y = 3x + 4
-8 + 1 = -9 and its less than
Answer:
Option A)
Confidence interval decreases
Step-by-step explanation:
If we increase the sample size, then,
- The standard error of the interval decrease.
- If the standard error increase, the margin of error of the interval decrease.
- If the margin of error decreases, the width of the confidence level decreases, hence, the confidence interval become narrower.
Thus, the correct answer is
Option A)
Confidence interval decreases
