Answer:
2 5/8
Step-by-step explanation:
The expected value is the sum of each outcome times its probability.
X = 1 (3/16) + 2 (1/4) + 3 (3/8) + 4 (1/8) + 5 (1/16)
X = 3/16 + 1/2 + 9/8 + 1/2 + 5/16
X = 2 5/8
I got the last one there are 40,000 worker bees living in one hive
I just got to get the mass of
2(3x+4y) = 2(24)
6x+8y = 48
Add both the equations
6x + 8y = 48
+ x - 8y = -20
—————————
7x = 28
x = 28/7
x = 4
Plug in this value in the second equation
(4) - 8y = -20
-8y = -24
y = -24/-8
y = 3
Therefore:
x = 4
y = 3
The answer would be
7,000,000,000
Since the lines are parallel their slopes are equal. So, the equation is y=4x+b
Now we need to find the y-intercept, which is b.
Now, Plug in point p to find b:
3=4*(-1)+b
b=3+4=7
The equation is: y=4x+7
