Suppose the sample space for a continuous random variable is 0 to 40. If the area under the density curve for the variable from 0 to 6 is 0.15, what is the
area under the density curve from 6 to 40?
O A. 0.985
OB. 0.85
O C. 0.95
OD. 0.15

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

125 yards

step-by-step explanation:

i take 75 plus 50.

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
