Answer:

Height of density function is equal to \dfrac{1}{22}.

Step-by-step explanation:

Given that

Lower bound= -4 and upper bound=18 and we need to find height of density function.

We know that height ofProbability density function given as

Height =\dfrac{1}{Upper\ bound -lower\ bound}

Now by putting the values in the above formula we will get

Height =\dfrac{1}{18 -(-4)}

Height =\dfrac{1}{22}

So height of density function is equal to \dfrac{1}{22}.

Answer:

The  height of the density function is \frac{1}{22}

Step-by-step explanation:

Given : A random variable X follows the continuous uniform distribution with a lower bound of −4 and an upper bound of 18.

To find : What is the height of the density function f(x)?

Solution :

According to question,

The height of the density function is given by,

f(X)=\frac{1}{b-a}

Where, a is the lower bound a=-4

b is the upper bound b=18

Substitute the value in the formula,

f(X)=\frac{1}{18-(-4)}

f(X)=\frac{1}{18+4}

f(X)=\frac{1}{22}

Therefore, The  height of the density function is \frac{1}{22}

Answer: second option y = 2(x + 7/2)^2 + 1/2

Explanation:

1) given:

y = (x + 3)^2 + (x + 4)^2

2) expand the binomials:

y = x^2 + 6x + 9 + x^2 + 8x + 16

3) add like terms:

y = 2x^2 + 14x + 25

4) take common factor 2 of the first two terms:

y = 2 (x^2 + 7x) + 25

5) complete squares for x^2 + 7x

x^2 + 7x = [x +(7/2)x ]^2 - 49/4

6) substitue x^2 + 7x = (x + 7/2)^2 - 49/4 in the equation for y:

y = 2 [ (x + 7/2)^2  - 49/4] + 25

7) take -49/4 out of the square brackets.

y = 2 (x + 7/2)^2 - 49/2 + 25

8) add like terms:

y = 2(x + 7/2)^2 + 1/2

And that is the vertex for of the given expression.

You can upgrade lighting at your factory to LED bulbs that cost $6.95 each and last an average of 5 years. It costs S3 in labor
marshall27 [118]

Answer:

11.95 dollars

Step-by-step explanation:

Cost of one LED bulb = 6.95 dollars

Cost of changing one bulb = 3 dollars

Life of each bulb = 5 years.

In 10 years, only one time after 5 years the bulbs would have been changed

Hence cost of 100 lamps = 695 and

cost of changing once = 500

Total cost = 1195 dollars for 11 years

Divide this by 10 years to get average cost per year

Cost of 100 lamps per year = 1195/100 = 11.95 dollars

Over [174]

Answer:

The answers are A. and B.

Step-by-step explanation:

Since the area of the largest square is 36. We need two numbers that equal 36. and A. had 6 and 30 so i picked it and it was right and B. is 28 and 8 which also equals 36. But, C. is 4 and 16 which is not 36. So A. and B. are the answers. Hope this helps! :)
