Answer:
the answer is 67!! I think I asked my teacher and thats what they said.
Step-by-step explanation:
About 32.34% of the values do not lie between the z-scores of -1.3 and 0.75.
First, we need to find the region between the z-scores.
If you look at a normal distribution table, you will get the following values:
0.75 = 77.34%
-1.3 = 9.68%
Subtraction those gives us the area between the z-scores.
77.34 - 9.68 = 67.66%
Now, just subtract that value from 100% to get the amount outside of the area.
100 - 67.66 = 32.34%
Answer:
-11 x 8 = -88
Step-by-step explanation:
negative times positive = negative
negative times negative = positive
positive times positive = positive
Direct variation always has the relationship y=kx. Indirect inverse variation always has the relationship y=k/x.
In this case y=kx, where k=6, so this is a direct variation.
Answer:
An appropriate method is to generate a simple random sample of all single-family homes in the city or a stratified random sample by taking a simple random sample from each of the ten district neighborhoods.
Step-by-step explanation:
Since, the city is very large and it is divided into ten districts. So, collecting sample from one district or any particular are did not give the correct estimate of whole city. So, the appropriate method to collect sample is taking the sample randomly from each district and this type of sampling method is called Stratified Sampling.
