The ratio of women to men working for a company is 5 to 7. If there are 140 men working for the company, what is the total numbe

Thepotemich [5.8K]

So women:men=5:7
for every 5 units of women, there are 7 units of men so
there are 140 men and that equals 7 units so
140=7 units
solve for 1 unit
140/7=20
1 unit=20
women=5 units
5 times 20=100
women=100
total=women+men=100+140=240
another way would be to add up the units (5+7=12) and multiply by the amount per 1 unit

Evgesh-ka [11]

Answer: The required time is 0.743.

Step-by-step explanation:

Since we have given that

$\lambda=0.02$

We need to find the time above which is 68% of the cameras have to be reset.

So, exponential distribution would be

$f(x)=0.02e^{-0.02}$

So, it becomes,

$P(X$

Hence, the required time is 0.743.
