Answer:
With Two points is enough to describe this graph
![\left[\begin{array}{ccc}\frac{4}{6} &0\\0&-4\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D%5Cfrac%7B4%7D%7B6%7D%20%260%5C%5C0%26-4%5C%5C%5Cend%7Barray%7D%5Cright%5D)
Step-by-step explanation:
Interception with Y axis (y=0), thus we have the following equation:
The point for this is (4/6 , 0)
Interception with x axis (x=0), thus we have the following equation:
The point for this is (0, -4)
Answer:
C. 0.98
Step-by-step explanation:
Let x be the mean of Company A and B annual profit and x/2 and y are standard deviation of Company A and B annual profit.
P(B<0) = 0.9*P(A<0)
P(Z<(0-x)/y) = 0.9*P(Z<(0-x)/(x/2))
P(Z<-x/y) = 0.9*P(Z<-2)
P(Z<-x/y) = 0.0205
x/y =2.04
Or y/x = 1 /2.05
y/x =0.49
Ratio of the standard deviation of company B annual profit to the standard deviation of company A annual profit =y/(x/2)
= 2*(y/x)
= 2*0.49
= 0.98
Answer:
(4c-1)(y+3)
Step-by-step explanation:
4c(y+3) -(y+3)
=(4c-1)(y+3)
1 mile is 5280 feet so when adding both 5,280 and 250 feet you get 5,530.
