Answer:
Area=6
Step-by-step explanation:
Area= lengthxwidth
- the pigpen is not a square so it could be a rectangle or any other shape with four sides.
- since the pigpen has four equal angles and it's not a square it's a rectangle.
- one side of the pigpen is three feet long--REMEMBER THAT!!!
- one foot short of 7 feet is six feet and that is the distance around the pigpen or the perimeter
Time to solve
- because the perimeter is 6 feet and one of the sides is three feet
- we divide 6 by 3 and get two which is our width
- we then multiply 2x3 to get 6
Answer:
this cant be possible like what?
Step-by-step explanation:
if so i would say its =-1 bc everytime u times by -1 its gonna be the same. i dont get this sorry
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
