Answer:
The smallest possible value of Pr{X = 3} is U = 0
Step-by-step explanation:
The number of trial is n = 3
The mean is E(X) = 1.8
Gnerally given that every probability value lies between 0 and 1 ,
let U be the smallest possible value of Pr{X = 3}
it then mean that U= 0 because in the range which probability values can take , the smallest value is zero
So
The smallest possible value of Pr{X = 3} is U = 0
Answer:
36 degrees
Step-by-step explanation:
since, m<AOB is a right angle, we shall just create an equation:
M<AOB+M<BOC=90 degrees
Substitute: 6z-12+3z+30=90
Solve: 6z+3x=9z
-12+30=18
so, 9z+18=90 degrees
-18 -18
9z=72
z=8
So if z=8, then we should fit it so that it matches measure of AOB.
6z-12
6 times 8=48
48-12= 36

Answer: Hello there!
we know that she earns $8 in the job 1 and $12 in the job 2; let's call J1 the amount of hours worked in the job 1, and J2 the number of hours worked in the job 2, then we have the system of equations:
J1 + J2 = 30
J1*$8 + J2*$12 = $268
We can isolate J1 in the first equation and obtain:
J1 = 30 - j2, and now we can replace this in the second equation and obtain the value of j2:
J1*$8 + J2*$12 = $268
(30 - J2)*$8 + J2*$12 = $268
$240 +$4*J2 =$268
J2 = ($268 - $240)/$4 = 28/4 = 7 hours
She worked 7 hours in the job 2
you can replace it in the first equation and get:
7 + J1 = 30
J1 = 30 - 7 = 23 hours
she worked 23 hours in the job 1.
