Marina86 [1]

Answer:

Bob's typing speed is 39 words per minute.

Bill's typing speed is 58 words per minute.

Step-by-step explanation:

<u>Given : </u>

Bill can type 19 words per minute faster than bob. their combined typing speed is 97 words per minute.

<u>To Find : </u>

Bobs typing speed

<u>Solution : </u>

Let the bobs typing speed is x

According to the given question :

Bobs typing speed is x

Bill's typing speed is 19+x

Their combined speed is 97 words per minute.

<u>Solving value x : </u>

x + 19+x = 97

2x + 19 = 97

2x = 97 - 19

2x = 78

x = 78/2

x = 39

Bobs typing speed = 39

Bill's typing speed 39 + 19 = 58

Hence, Bobs speed is 39 words per minute.

A particular automatic sprinkler system has two different types of activation devices for each 3 sprinkler head. One type has a
zmey [24]

Answer:

There is an 85% probability that the sprinkler head will be activated.

Step-by-step explanation:

We have these following probabilities:

50% of the first sprinkler being triggered

90% of the first sprinkler being reliable

50% of the second sprinkler being triggered

80% of the second sprinkler being reliable.

What is the probability that the sprinkler head will be activated?

P = P_{1} + P_{2}

P_{1} is the probability of the first sprinkler being triggered and activated. So:

P_{1} = 0.5*0.9 = 0.45

P_{2} is the probability of the second sprinkler being triggered and activated. So:

P_{2} = 0.5*0.8 = 0.40

P = P_{1} + P_{2} = 0.40 + 0.45 = 0.85

There is an 85% probability that the sprinkler head will be activated.
