Answer:
300
Step-by-step explanation:
Let's call N the total number of televisions. We have that 240 televisions make up of 80% of the total number of televisions, so we can rewrite it as
where 0.80 means 80 % (
. By solving the equation above, we find
So, the total number of televisions is 300.
Expected value E(x) = 0.6(200,000) + 0.2(100,000) - 0.2(200,000) = 120,000 + 20,000 - 40,000 = 100,000
Therefore, the expected value is $100,000, so the company should build the mousetrap.
Answer:
8%
Step-by-step explanation:
1) create equation
y = (4)2.5 + 125
2) simplify
y = 10 + 125
y = 135
3) find difference
x = 135-125/125
x = 0.08
x = 8%
Answer:
x = 37
Step-by-step explanation:
Power Theorem: 10 x (10 + 26) = 8 x (8 + x)
360 = 8 x (8 + x)
8 + x = 45
x = 37
D is the one that is decreasing
