Solve each equation below for x show all work and check your answer by substituting it back into the equation and verifying that

Viefleur [7K]

Answer:

The equations are

(a) x/3 = 6

(b) (5x + 9)/2 = 12

(d) 5/x = 20/8

The answers to the question are

(a) x = 18

(b) x = 3

(d) x = 2

Step-by-step explanation:

(a) x/3 = 6

Therefore x = 3×6 = 18

x =18

Substituting the value of x in the above equation, we have

18/6 = 3 verified

(b) (5x + 9)/2 = 12

Multiplying both sides by 2 gives

(5x + 9)/2 × 2 = 12×2 = 24

5x + 9 = 24 or x = (24-9)/5 = 3

Substituting the value of x in the above equation, we have

(5×3 + 9)/2 = 24/2 = 12 verified

x = 3

Multiplying both sides by 4, we have

x/4×4 = 9/6×4 = 6

x = 6

Substituting the value of x in the above equation, we have

(6/4 = 9/6 = 3/2 verified

(d) 5/x = 20/8

Inverting both equations, we have

x/5 = 8/20

Multiplying both sides by 20 we have x/5 × 20 = 8/20 × 20 or 4x = 8 and x = 2

Substituting the value of x in the original equation, we have

2/5 = 2/5 = 8/20 verified

x = 2

▹ Answer

y = 15, -15

▹ Step-by-Step Explanation

This is considered a 'square root' since we have to find y^2.

15 * 15 = 225

-15 * -15 = 225

Both of these values work for y, so the answer is 15, -15.

Hope this helps!

According to insurance records, a car with a certain protection system will be recovered 87% of the time. If 600 stolen cars are

White raven [17]

Answer:

The mean and standard deviation of the number of cars recovered after being stolen is 522 and 8.24 respectively.

Step-by-step explanation:

We are given that according to insurance records, a car with a certain protection system will be recovered 87% of the time.

Also, 600 stolen cars are randomly selected.

Let X = Number of cars recovered after being stolen

The above situation can be represented through binomial distribution;

$P(X=r)=\binom{n}{r}\times p^{r} \times (1-p)^{n-r} ;x=01,2,3,......$

where, n = number of trials = 600 cars

r = number of success

p = probability of success which in our question is the probability

that car with a certain protection system will be recovered,

i.e. p = 87%.

So, X ~ Binom(n = 600, p = 0.87)

Now, the mean of X, E(X) = $n \times p$

= $600 \times 0.87$ = 522

Also, the standard deviation of X, S.D.(X) = $\sqrt{n \times p \times (1-p)}$

= $\sqrt{600 \times 0.87 \times (1-0.87)}$

= 8.24
