Answer:
Step-by-step explanation:
y = -1/5x + 1
the slope here is -1/5.....a perpendicular line will have a negative reciprocal slope. All that means is flip the slope and change the sign. So our perpendicular slope will have to be 5.....(because I flipped -1/5, making it -5/1, then I switched the sign...making it 5/1 or just 5)
y = mx + b
slope(m) = 5
(-5,1)...x = -5 and y = 1
now we sub and find b, the y int
1 = 5(-5) + b
1 = - 25 + b
1 + 25 = b
26 = b
so ur equation for the perpendicular line is : y = 5x + 26
Answer: C

It is true that the confidence intervals for the mean provide an estimate for where the true mean lies.
In statistics, a confidence interval denotes the likelihood that a population parameter will fall between a set of values for a given proportion of the time. A confidence interval depicts the likelihood that a parameter will fall between two values near the mean. Confidence intervals quantify the degree of uncertainty or certainty in a sampling procedure.
The mean is a basic mathematical average of two or more values. There are two sorts of means that may be calculated: the arithmetic mean and the geometric mean. A mean tells you the average of a bunch of values, which helps you contextualize each data point.
