Answer:
Im sorry! can you please translate this?
Step-by-step explanation:
The answer:
according to the image the coordinates of pre image are:
A(-7, 2), B(-5, 3) C(-2, 2) and D(-5, 1)
<span>Kite ABCD is reflected over the line y = x, the main rule to find the coordinates of the images is (y, x)
for example if A(-7, 2) the image A' is A'(2, -7)
the answer is </span><span>(x,y)→(y,x); A' is at (2, −7)</span>
Answer: 60.93 < μ < 69.07
Step-by-step explanation: The true mean of a set of data is between an interval of values with a percentage of precision, e.g., a <u>99% confidence interval</u> means we are 99% confident the true mean is between the lower and upper limits.
To find the interval, use
x±
z is z-score related to the % of confidence level
In this case, a 99% confidence interval is 2.576
x is sample mean
Calculating:

x = 65
65±
65±4.07
Confidence Interval: 60.93 < μ < 69.07
Meaning that we are 99% sure the population means is between 60.93 and 69.07.
