The two events have independent probabilities.

To get the probability of both of the events happening, you should multiply them:

2% (or 0.02) * 2.5% (or 0.025) = 0.0005 or 0.05%

The probability that both machines will break down on a given day is 0.05%.

What is the value of r in: 1/7(105+r)=20
stealth61 [152]
Use the distributive property.

1/7(105 + r) = 20
15 + (1/7)r = 20

Then subtract each side of the equation by 15.

15 + (1/7)r = 20
(1/7)r = 5

Divide both sides by 1/7.

(1/7)r = 5

r = 35

So, the answer to this question is r is equal to 35.

Solve (x − 2) = 3<br> Give your solutions correct to 3 significant figures.
Pachacha [2.7K]

Answer:

(x − 2) = 3

Remove the bracket

x - 2 = 3

Group the constants at one side of the equation

x = 2 + 3

x = 5

Therefore x = 5.00 to 3 significant figures.

Hope this helps
