Answer:

So the Solution is

$x = 4\ , x = -2$

Step-by-step explanation:

Solve for x: 4|2x − 2| + 10 = 34.

Step 1. Subtracting 10 on both the sides we get

$4|2x-2|+10-10=34-10\\\\4|2x-2|=24$

Step 2. Dividing both the side by 4 we get

$\dfrac{4|2x-2|}{4}=\dfrac{24}{4}\\\\|2x-2|=6$

Step 3. Removing Modulus sign we get two values

$2x-2=6\ or\ 2x-2=-6\\\\2x=6+2\ or\ 2x=-6+2\\\\2x=8\ or\ 2x=-4\\\\x=\dfrac{8}{2} \ or\ x=\dfrac{-4}{2} \\\\x=4\ or\ x=-2\\$

So the Solution is

$x = 4\ , x = -2$

Consider the following binomial experiment. A company owns 4 machines. The probability that on a given day any one machine will

const2013 [10]

Answer:

There is a 73.11% probability that at least 2 machines will break down on a given day.

Step-by-step explanation:

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinatios of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

In this problem we have that:

There are 4 machines, so $n = 4$ .

The probability that on a given day any one machine will break down is 0.53. This means that $p = 0.53$ .

What is the probability that at least 2 machines will break down on a given day?

$P(X \geq 2) = P(X = 2) + P(X = 3) + P(X = 4)$

In which

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 2) = C_{4,2}.(0.53)^{2}.(0.47)^{2} = 0.3723$

$P(X = 3) = C_{4,3}.(0.53)^{3}.(0.47)^{1} = 0.2799$

$P(X = 4) = C_{4,4}.(0.53)^{4}.(0.47)^{0} = 0.0789$

$P(X \geq 2) = P(X = 2) + P(X = 3) + P(X = 4) = 0.3723 + 0.2799 + 0.0789 = 0.7311$

There is a 73.11% probability that at least 2 machines will break down on a given day.

Pepsi [2]

Answer:

$50 and

$30

Step-by-step explanation:

Question 1. Principal = $500

Rate = 5%

Time = 2yesrs

Interest = PRT /100

= 500 x 5 x 2 /100

= 5000/100

= $50

Interest = PRT/100

Principal P =$500

Rate = 3%

Time = 2 years

Therefore, interest =

500 x 3 x 2 /100

= 3000/100

= $30
