Answer:

a) 10x² - 3x - 18

b) 14x + 6

Step-by-step explanation:

Given:

length = 5x + 6

width = 2x - 3

Tables usually have rectangular shape.

a) Area of the table

Area of a rectangle

A = length × width

Insert values into formula.

A = length × width

A = (5x + 6) × (2x - 3)

A = 10x² - 15x + 12x - 18

A = 10x² - 3x - 18

b) Perimeter of the table

Perimeter of a rectangle

P = 2 × length + 2 × width

P = 2(5x + 6) + 2(2x - 3)

P = 10x + 12 + 4x - 6

P = 14x + 6

Historical data for a local manufacturing company show that the average number of defects per product produced is 2. In addition

charle [14.2K]

Answer:

The probability that there will be a total of 7 defects on four units is 0.14.

Step-by-step explanation:

A Poisson distribution describes the probability distribution of number of success in a specified time interval.

The probability distribution function for a Poisson distribution is:

$P(X = x)=\frac{e^{-\lambda}\lambda^{x}}{x!}, x=0,1,2,3,...$

Let X = number of defects in a unit produced.

It is provided that there are, on average, 2 defects per unit produced.

Then in 4 units the number of defects is, $(2\times4)=8$ .

Compute the probability of exactly 7 defects in 4 units as follows:

$P(X = x)=\frac{e^{-\lambda}\lambda^{x}}{x!}\\P(X=7)=\frac{e^{-8}8^{7}}{7!}\\=\frac{0.0003355\times2097152}{5040}\\ =0.1396\\\approx0.14$

Thus, the probability of exactly 7 defects in 4 units is 0.14.

Can 12/15 be simplify

Semmy [17]

Yes 12/15 can be simplified.

To simplify 12/15 find the greatest common multiple. The greatest common multiple of 12/15 is 3. Now divide 12/15 by 3.

12 ÷ 3 = 4
15 ÷ 3 = 5

4/5 is the simplified version of 12/15

jillian is trying to save water, so she reduces the size of her square grass lawn by 8 feet on each side. the area of the smalle

8_murik_8 [283]

We can solve this equation by using the Square Root Method.
First, take the square root of each side of the equation:
(x-8)^2 = 144 becomes x-8 = 12
Then add 8 to both sides.
x=20

The original lawn was d. 20 feet by 20 feet.
