Answer:
a. 0.71
b. 0.9863
Step-by-step explanation:
a. From the histogram, the relative frequency of houses with a value less than 500,000 is 0.34 and 0.37
-#The probability can therefore be calculated as:
Hence, the probability of the house value being less than 500,000 is o.71
b.
-From the info provided, we calculate the mean=403 and the standard deviation is 278 The probability that the mean value of a sample of n=40 is less than 500000 can be calculated as below:
Hence, the probability that the mean value of 40 randomly selected houses is less than 500,000 is 0.9863
4/6
= (4/2) / (6/2) (divide both numerator and denominator by 2)
= 2/3
The final answer is 2/3~
Step-by-step explanation:
No it would because you have to find the number for why and the two is the power so no it not going to be.
Answer:
The answer stays the same.
Step-by-step explanation:
For example, if you have 1/2 and multiply the numerator and the denominator by 4, you get 4/8. 4 divided by 8 still gives you 1/2.
The general equation of a line is:
When m is the gradient and x1 and y1 are the coordinates of the points on the line
Therefore:
