An automobile manufacturer obtains the microprocessors used to regulate fuel consumption in its automobiles from three microelec

Anastaziya [24]

Answer:

The probability that a randomly selected automobile manufactured by the company will have a defective microprocessor is 6.2 %.

Step-by-step explanation:

Given:

The probability of getting a microprocessor from firm A is, $P(A)=45\%=0.45$

The probability of getting a microprocessor from firm B is, $P(B)=30\%=0.30$

The probability of getting a microprocessor from firm C is, $P(C)=25\%=0.25$

Now, let event D be having a defective microprocessor at random.

So, as per the question,

Probability of producing a defective microprocessor from firm A is, $P(D/A)=6\%=0.06$

Probability of producing a defective microprocessor from firm B is, $P(D/B)=7\%=0.07$

Probability of producing a defective microprocessor from firm C is, $P(D/C)=5.5\%=0.055$

Now, probability of having a defective microprocessor when selected at random is given as:

$P(D)=P(A)\cdot P(D/A)+P(B)\cdot P(D/B)+P(C)\cdot P(D/C)\\P(D)=(0.45\times 0.06)+(0.30\times 0.07)+(0.25\times 0.055)\\P(D)=0.027+0.021+0.01375\\P(D)=0.06175\ or\ P(D)=0.06175\times 100\approx 6.2\%$

Therefore, the probability that a randomly selected automobile manufactured by the company will have a defective microprocessor is 6.2 %.

In the first week of July a record 1120 people went to the local swimming pool in the second week 105 fewer people went to the p

Westkost [7]

Answer:

25%

Step-by-step explanation:

The number of people who went to the local swimming pool in the;

first week = 1120

second week ( 105 fewer people) = 1120 - 105 = 1015

third week (135 more people) = 1015 + 135 = 1150

fourth week (310 fewer people|) = 1150 - 310 = 840

The percent decrease in the number of people who went to the pool over these four weeks

= (1120 - 840)/1120 * 100%

= 280/1120 * 100%

= 1/4 * 100%

= 25%

It means that the number of people who went to the local swimming pool over the 4 weeks decreased by 25%
