Answer:
x=92 y=23
Step-by-step explanation:
Let them be x and y respectively
so given
x-y=69
and
x/y=4 x=4y
so we can write
x-y=69
as
4y-y=69 3y=69 y= 69/3 = 23
now y is 23
so putting in any equation will give the value of x
so
x-23=69 x=92
Answer:
They meet a line. Therefore, if two planes cut one another, then their intersection is a straight line.
Step-by-step explanation:
Answer:
Step-by-step explanation:
(6 gal)/(4/7 fence) = (21/2 gal)/fence = (10.5 gal)/fence
The probability that x >17 will be found as follows:
the z-score is given by:
z=(17-15.2)/0.9=2
Thus
P(X>17)=1-P(x<17)=P-(z=2)
=1-0.9772
=0.0228
