According to insurance records, a car with a certain protection system will be recovered 95% of the time. If 800 stolen cars are

Lapatulllka [165]

Answer: Mean = 760

Standard deviation = 6.16

Step-by-step explanation:

Given : The number of trials: $n=800$

The probability that a certain protection system will be recovered : $p=0.95$

We know that the mean and standard deviation of binomial distribution is given by :_

$\text{Mean}=np$

$\text{Standard deviation}=\sqrt{np(1-p)}$ , where n is the number of trials and p is the probability of success.

Now, the mean and standard deviation of the number of cars recovered after being stolen is given by :-

$\text{Mean}=800\times0.95=760$

$\text{Standard deviation}=\sqrt{800\times0.95(1-0.95)}\\\\=6.164414002\approx6.16$

Hence, the mean is 760 and standard deviation is 6.16 .

Solve the system using elimination. –10x – 3y = –18 –7x – 8y = 11

Naily [24]

ANSWER

x=3, y=-4

EXPLANATION

The given system is :

First equation:

$- 10x - 3y = - 18$

Second equation:

$- 7x - 8y = 11$

Let us multiply the first equation by 7 to get,

Third equation;

$- 70x - 21y = - 126$

Let us multiply the second equation too by 10 to get,

Fourth equation:

$- 70x - 80y = 110$

Subtract the fourth equation from the third equation:

$- 21y + 80y = - 126 - 110$

$59y = -236$

Divide both sides by 59.

$y = - 4$

Put y=-4 into the second equation and solve for x.

$- 7x - 8( - 4) = 11$

$- 7x + 32 = 11$

$- 7x = 11 - 32$

$- 7x = - 21$

$x = 3$

The solution is x=3, y=-4
