The weekly demand for an item in a retail store follows a uniform distribution over the range of 50 to 100. What would be the weekly demand if its corresponding computer-generated value is 0.4?a. 60b. 70c. 75d. 80
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
What is the property of a uniformly distributed random variable?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

5 7\10 × 7 4\16=????? I'm trash with multypliing
9514 1404 393
Answer:
41 13/40
Step-by-step explanation:
Generally, you're told to multiply mixed numbers by converting each to an improper fraction:
5 7/10 = (5·10 +7)/10 = 57/10
7 4/16 = (7·16 +4)/16 = 116/16
The fractions are multiplied by multiplying their numerators to get the numerator of the result, and multiplying their denominators to get the denominator of the result.
[tex](5\frac{7}{10})(7\frac{4}{16})=\dfrac{57}{10}\cdot\dfrac{116}{16}=\dfrac{57\cdot116}{10\cdot16}=\dfrac{6612}{160}\\\\=41+\dfrac{52}{160}=\boxed{41\frac{13}{40}}[/tex]
__
You don't have to mess with reducing the fraction of the result if you reduce the fraction 4/16 to 1/4 to begin with. Then the product is (57/10)(29/4).
_____
Alternate solution
You can also treat this as the product of two sums. The distributive property is handy for this.
(5 + 7/10)(7 + 1/4) = (5)(7) +(5)(1/4) +(7/10)(7) +(7/10)(1/4)
= 35 +5/4 +49/10 +7/40
= 35 +1 +1/4 + 4 + 9/10 + 7/40 . . . . take out the integer parts
= 40 +10/40 +36/40 +7/40 . . . . . . use 40 as a common denominator
= 40 +53/40 = 41 13/40

Step-by-step explanation:
Two parallel lines are cut by a transversal. What is the measure of angle6 ?
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)
What are parallel lines?"The lines in the same plane that are at equal distance from each other and never meet."
What is transversal?"A line that passes through two lines in the same plane at two distinct points in the geometry. "
What are opposite angles?"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)

A phone company has two long distance
calling plans. The first plan is $25 per month
for unlimited long distance calling. The second
plan is $10 per month plus $0.05 per minute
of long distance calling. After how many
minutes oflong distance calls will it be cheaper
for a customer to purchase the first plan?
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.
