Answer:
4
Step-by-step explanation:
The mean is the average of the numbers.
if you rearrange the data, you will get the order, 3,3,4,5,5.
you add all of them together to get the number twenty, then you divide 20 by the total number of data plots which is five. Then you get the number 4 which is your answer
3+3+4+5+5 = 20
20/5 = 4
They read 10 + 14 + 16 = 40 out of 240 pages by the third day, putting them 40/240 = 1/6 of the way through the whole thing. If they've read 1/6 of the book, they have 5/6 left until they finish the whole thing.
Answer:
1.1264
Step-by-step explanation:
Given : An experiment using 35 guinea pigs is set up to study the weight of the pigs after injecting them with a drug.
To Find: If the population mean is 23.5 grams with a standard deviation of 3.4 grams, what is the margin of error of the sample mean?
Solution:
n = 35
Confidence interval = 95%. So, z =1.96
Margin of error =
Margin of error =
Margin of error =
Hence the margin of error of the sample mean is 1.1264.
Answer:
y = 5x + 7
Step-by-step explanation:
1. Substitue the numbers into their spots.
7 = 5(2)+b
2. Find b by simplifying
7 = 10 + b
-3 = b
3. Substitute it back in since parallel lines have the same slope.
Answer:
The coordinates of S' is (-10,6)
Step-by-step explanation:
The coordinates of rectangle RSTU are R(-5, 1), S(-5,3), T(4, -3), and
U(4, 1).
When the rectangle is dilated by a scale factor of 2.
Then the mapping will be;
This implies that:
The coordinates of S' is (-10,6)
