A professor, transferred from Toronto to New York, needs to sell his house in Toronto quickly. Someone has offered to buy his ho

I am Lyosha [343]

Answer:

(a) = 40%

(b) = 28%

(c) Expected value = $222,500

Standard deviation = $7,216.88

Step-by-step explanation:

This is a normal distribution with a = 210,000 and b =235,000

(a) The probability that he will get at least $225,000 for the house is:

$P(X\geq 225,000) =1 -\frac{225,000-a}{b-a} =1-\frac{225,000-210,000}{235,000-210,000} \\P(X\geq 225,000) =0.4= 40\%$

(b)The probability he will get less than $217,000 is:

$P(X\leq 217,000) =\frac{217,000-a}{b-a} =\frac{217,000-210,000}{235,000-210,000} \\P(X\leq 217,000) =0.28= 28\%$

(c) The expected value (E) and the standard deviation (S) are:

$E=\frac{a+b}{2}=\frac{210,000+235,000}{2}\\ E=\$222,500\\S=\frac{b-a}{\sqrt{12}}=\frac{235,000-210,000}{\sqrt{12}}\\S=\$7,216.88$

How do you solve this equation ?

nata0808 [166]

The first step to solving this is to solve the equation for x
x = - 21/5 - y
4x + 4y = -14
now,, substitute the given value of x into the equation "4x + 4y = -14"
4( - 21/5 - y) + 4y = -14
next,, solve the equation for y
y∈∅
since this system has no solution for y, your answer is (x,y)∈∅
let me know if you have any further questions
