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:
14 square meters
Step-by-step explanation:
If you break the figure into two parts you get 3x2 and 2x4. Multiplying those will give you 6 and 8. Add 6 and 8 to get 14. Hope this helped! :D
Add or subtract like terms
2x+3y=5x-y
7x=2y
since you can’t divide or add any more like terms together there isn’t anything else to solve
answer ~ 7x=2y

Answer:4^2≈50.26548
Step-by-step explanation:
πr2.
Where r is the radius and π≈3.14 , the ratio of a circle's circumference to its diameter.
Plugging in 4 from the radius, we get.
42π
⇒16π inches.
This is our exact answer. Alternatively, we can plug in 3.14 for π to get.
50.26 inches.
