Answer:
No. A = 32 square units B= 42 square units
Explanation:
When finding the area of composite figures, add the area of each figure.
Well the answer would be 120=120 and 68=68
67°C
89°C
Dont quote me on this but I am almost 100 percent sure about it
Answer: One sample z test for means
Step-by-step explanation:
From the information given, the sample size is large. It is greater than 30. Again, the population standard deviation is given. This means that the test statistic would be the z score which is determined by the formula
z = (x - µ)/σ
Where
x = sample mean
µ = population mean
σ = population standard deviation
The probability value would be determined from the normal distribution table.
Therefore, the hypothesis test that should be used is
One sample z test for means
Step-by-step explanation:
Here is a table.
