Step-by-step explanation:
the line passes through (0,-2) and perpendicular to the graph of y=5x+7.
solution :
the slope = -1/5
the equation :
y+2 = -1/5 (x-0)
y = -1/5x - 2
Never due to if they have different slopes they can only have 1 solution.
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
Answer:
B: The value of 7 in 7.5 is 1
Step-by-step explanation:
Because in decimals <u>1</u>.0 is the ones place, the 7 in <u>7</u>.5 is in the ones place, hope this helps!
