Answer:

x = 4; y = 2

Step-by-step explanation:

(1) 3x + 2y = 16

(2) 2x – 2y = 4 Add (1) and (2)

5x = 20 Divide each side by 5

(3) x = 4 Substitute (3) into (2)

2×4 – 2y = 4

8 - 2y = 4 Subtract 16 from each side

-2y = -4 Divide each side by -2

y = 2

<em>Check: </em>

(1) 3×4 + 2×2 = 16

12 + 4 = 16

16 = 16

(2) 2×4 – 2×2 = 4

8 - 4 = 4

4 = 4

a shipping company charged $15 to ship a package and 5% to ensure the package what was total cost to ship this

postnew [5]

Answer:

15.75

Step-by-step explanation:

So we know 5% is 1/20 out of 100 (20x5=100) so then we need to set up the equation to find how much 5% of 15 is. Which is .75 cents. So we then add the 75 cents to the already $15 shipping fee to get an answer of 15 dollars and seventy five cents.

The number of failures of a testing instrument from contamination particles on the product is a Poisson random variable with a m

Mazyrski [523]

Answer:

The probability that the instrument does not fail in an 8-hour shift is $P(X=0) \approx 0.8659$

The probability of at least 1 failure in a 24-hour day is $P(X\geq 1 )\approx 0.3508$

Step-by-step explanation:

The probability distribution of a Poisson random variable X representing the number of successes occurring in a given time interval or a specified region of space is given by the formula:

$P(X)=\frac{e^{-\mu}\mu^x}{x!}$
