Answer:

x = 3, y = 11

Step-by-step explanation:

Given

2x + 3xi + 2y = 28 + 9i

Compare coefficients of like terms on both sides.

Comparing i terms

3x = 9 ( divide both sides by 3 )

x = 3

Comparing constant terms

2x + 2y = 28 ← substitute x = 3

2(3) + 2y = 28

6 + 2y = 28 ( subtract 6 from both sides )

2y = 22 ( divide both sides by 2 )

y = 11

According to police sources, a car with a certain protection system will be recovered 87% of the time. Find the probability that

WITCHER [35]

Answer: 0.01145

Step-by-step explanation:

We use Binomial distribution , where the probability of getting x successes in n trial is given by :-

$P(x)=^nC_xp^x(1-p)^{n-x}$ , p = probability of getting each success in each trial.

As per given

The proportion that a car with a certain protection system will be recovered= p=0.87

n= 8

Let x be the number of cars will be recovered.

Then, the probability that 4 of 8 stolen cars will be recovered:

$P(X=4)=^8C_4(0.87)^4(1-0.87)^{8-4}$

$=\dfrac{8!}{4!(8-4)!}(0.87)^4(0.13)^4\\\\= 70(0.57289761)(0.00028561)\\\\=0.0114537700474\approx0.01145$

Hence, the required probability is 0.01145.
