Switch y=2x+7 to 2x-y=-7 then multiply that equation by 2 to cancel out the y's. that ends up as 4x-2y=-14 which then you get x=-24. then you substitute x into one of the original equations y= 2(-24)+7 which equals y=-41
Answer: 13% or 0.1314
Step-by-step explanation: Binomial PDF on the calculator or by hand its
22 nCr 15 (0.60)^15(1-0.6)^7 = 0.131378
Answer:
8y+6y=288
Step-by-step explanation:
8y+6y= 12y
12y=288
12y divide by 12 = 288 divided by 12 =
y=24
a.
is a proper joint density function if, over its support, 
is non-negative and the integral of is 1. The first condition is easily met as long as 
. To meet the second condition, we require
b. Find the marginal joint density of 
and 
by integrating the joint density with respect to 
:
Then
c. This probability can be found by simply integrating the joint density:
Answer:
No, linear function graphs always have the x raised to the first power
