Answer:
2.5896
Explanation:
Zero power rule: The zero exponent rule states that any number raised to a power of zero equals one.
10^0 is 1, so nothing changes
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
Answer:
5b -5
Step-by-step explanation:
5(b - 1)
we apply distributive property:
5*b -5*1
5b -5
Im not sure if this really helps but I hope it does
