Answer:
168 square units
Step-by-step explanation:
From left to right, top to bottom
1. 5 x 10 = 50
2. 5 x 8 = 40
3. 5 x 6 = 30
For the triangles since there is 2 of them and there the same we play it like there is 1 square
4 & 5. 8 x 6 = 48
Now add all them
50 + 40 + 30 + 48
50 + 40 = 90
30 + 48 = 78
90 + 78 = 168
Answer:
The test statistic for Norah's test is
Step-by-step explanation:
Norah is in charge of a quality control test that involves measuring the amounts in a sample of bottles to see if the sample mean amount is significantly different than 500 ml.
This means that at the null hypothesis we test if the sample mean is 500 ml, that is:
At the alternate hypothesis, we test if it is differente than 500 ml, that is:
The test statistic is:
In which X is the sample mean, is the value tested at the null hypothesis, s is the standard deviation of the sample and n is the size of the sample.
500 is tested at the null hypothesis:
This means that
She takes a random sample of 16 bottles and finds a mean amount of 497ml, and a sample standard deviation of 6ml.
This means that
Calculate the test statistic for Norah's test.
The test statistic for Norah's test is
Answer:
about 56.55 (rounded)
Step-by-step explanation:
diameter = 2r
circumfrence = dimeter(pi)
18(pi)
= about 56.55 (rounded)
Answer:
I did the math and I think its 238 if I'm wrong I'm sorry
