In second equation multiply 2...


On solving the equation,




Hope it helps you..

-1 is the answer
If the variable is by itself or you don't see a coefficient, the coefficient is always 1
city X temperature is <u>-30</u>

Answer:
i) 25.25%
ii) 2.28%
Step-by-step explanation:
In this case we can use a normal distribution calculator. Setting the mean as 210000 and the standard deviation as 15000, we find that the area below 200000 is 0.2525. So the probability that the condominium will sell at $200.000 is 25.25%.
The area above 240000 is 0.0228, so the probability that the condominium will sell at $240.000 is 2.28%
F(-3)=-8(-3)^2 (take out the parenthesis and the negative because you can’t do the exponent of a negative number)
F(-3)= -8•3^2 (now you can do the exponent of 3)
F(-3)= -8•9 (multiply)
F(-3)= -72 this is your answer.
Hope this helps :D
