Answer: 70

Step-by-step explanation:

Given that :

Uniform range of distribution = 50 to 100

50 ≤ x ≤ 100

Difference between both values = 100 - 50 = 50

Range / difference = computer generated value

(Weekly demand - lower limit) / difference = computer generated value

(Weekly demand - 50) / 50 = 0.4

Weekly demand - 50 = 20

Weekly demand = 20 + 50

Weekly demand = 70

The weekly demand if the corresponding computer-generated value is 0.4 is given by: Option B: 70

A uniformly distributed random variable's probability is distributed uniformly in the interval in which it is defined. Thus, if X ranges from a to b, and pertains uniform distribution, then its probability density function is given by;

[tex]f(x) = \dfrac{1}{b-a}; a < x < b\\\\f(x) = 0; x < a , b < x[/tex]

For the given case,  the weekly demand(let it be tracked by random variable X) is in range 50 to 100.

The computer generated value shows:

[tex]\text{Computer generated value} = \dfrac{\text{Weekly demand} - \text{Lower limit}}{\text{difference between upper and lower limit}}[/tex]

(computer generated value is showing in range 0 to 1, the part occupied by the weekly value from starting, here as it is 0.4, so it means out of 50 values, it is 0.4 = 40% of (100 -50) = 20 (from start which is 50, thus, 50 + 20  = 70) )

As we've got:

Thus, the weekly demand is obtained as:

[tex]0.4 = \dfrac{\text{Weekly demand} - 50}{50}\\\\\text{Weekly demand} = 0.4 \times 50 + 50 = 70[/tex]

Thus, the weekly demand if the corresponding computer-generated value is 0.4 is given by: Option B: 70

Hello!

[tex]\large\boxed{\text{Yes, it does.}}[/tex]

In order to use the MVT, the function must be continuous over the given interval.

[tex]y = \frac{x^{2} }{4x}+4[/tex]

Simplifies to:

[tex]y = \frac{x}{4} + 4[/tex]

This is a linear equation that is continuous on the interval (-∞, ∞), which  means that it would also be continuous on the interval [-6, -2]. The MVT would apply to this function.

Answer:

x=75

Step-by-step explanation:

[tex]We\ are\ given\ that:\\AD\ is\ the\ altitude\ of\ \triangle ABC\\Hence,\\ADC=90[As\ altitudes\ intersect\ the\ base\ side\ at\ 90]\\Hence,\\As\ ADC=(x+15)\ and\ ADC=90\\x+15=90\\x=90-15\\x=75[/tex]

This is only the value of x in terms of AD being an altitude, and is independent off the sides.

Answer:

A

Step-by-step explanation:

Angle 3 and angle 6 are congruent because they are alternate interior angles. Angle 3 plus angle 1 is 180 degrees. So you just subtract 123 from 180 (180-123) and you get 57 degrees.

The measure of angle 6 is 57°

The correct answer is an option (A)

"The lines in the same plane that are at equal distance from each other and never meet."

"A line that passes through two lines in the same plane at two distinct points in the geometry. "

"The angles directly opposite to each other when two lines intersect in a plane."

For given question,

Line n and line p are parallel lines and line t is the transversal.

Here, angle 1 and angle 4 are opposite angles.

⇒ ∠1 = ∠4

We have been given that ∠1 = 123°

⇒ ∠4 = 123°

Also, angle 4 and angle 6 are interior angles on the same side of the transversal.

We know that each pair of interior angles on the same side of the transversal is supplementary.

⇒ ∠4 + ∠6 = 180°

⇒ 123° + ∠6 = 180°

⇒ ∠6 = 180° - 123°

⇒ ∠6 = 57°

Therefore, the measure of angle 6 is 57°

The correct answer is an option (A)

It is cheaper for a customer to purchase the first plan if they make more than 300 minutes of long-distance calls. The answer is (C) 300.

Let's denote the number of minutes of long-distance calls as x. Then, the total cost of the second plan would be:

Cost of Plan 2 = $10 + $0.05x

The total cost of the first plan is always $25, regardless of the number of minutes of long-distance calls.

So we need to find the value of x at which the cost of Plan 2 exceeds the cost of Plan 1, i.e. when:

$10 + $0.05x = $25

Subtracting $10 from both sides, we get:

$0.05x = $15

Dividing both sides by $0.05, we get:

x = 300

So for values of x greater than 300, the cost of Plan 2 will exceed the cost of Plan 1.

Answer:

x = 40

Step-by-step explanation:

The figure shows two similar triangles. Thus, the side lengths of similar triangles are proportional to each other. Therefore:

[tex] \frac{24}{24 - 15} = \frac{x}{x - 25} [/tex]

[tex] \frac{24}{9} = \frac{x}{x - 25} [/tex]

Cross multiply

[tex] 24(x - 25) = 9(x) [/tex]

[tex] 24x - 600 = 9x [/tex]

Subtract 24x from each side

[tex] - 600 = 9x - 24x [/tex]

[tex] - 600 = -15x [/tex]

Divide both sides by -15

[tex] 40 = x [/tex]

x = 40
