Taylor's computer randomly generate numbers between 0 and 4, as represented by the given uniform density curve.
A graph titled Random number generated by computer has random number on the x-axis. A horizontal line is at y = one-fourth from 0 to 4.
What percentage of numbers randomly generated by Taylor's computer are less than 0.5?
12.5%
25%
50%
87.5%
Picture posted below
12.5% is the percentage of numbers randomly generated by Taylor's computer that is less than 0.5.
An illustration of a numerical distribution with continuous results is a density curve. A density curve is, in other words, the graph of a continuous distribution. This implies that density curves can represent continuous quantities like time and weight rather than discrete events like rolling a die (which would be discrete). As seen by the bell-shaped "normal distribution," density curves either lie above or on a horizontal line (one of the most common density curves).
The percentage of numbers randomly generated by Taylor's computer are less than 0.5 is given by
P(0≤X≤0.5)
=[tex]\int_{0}^{0.5}\frac{1}{4}dx[/tex]
[tex]=\frac{1}{4}x|^{0.5}_{0}[/tex]
[tex]=\frac{1}{4}(0.5-0)[/tex]
[tex]=0.25(0.5)[/tex]
= 0.125

find the highest number of student of whom 125 apples, 150 oranges and 225 mangoes can be divided equally
Answer:
25
Step-by-step explanation:
find the greatest common factor (GCF) of the 3 quantities using prime factorisation.
125 = 5 × 5 × 5
150 = 2 × 3 × 5 × 5
225 = 3 × 3 × 5 × 5
Next, identify those prime factors that the 3 numbers have in common and multiply them.
the common factors are 5 × 5 = 25
then
125 ÷ 25 = 5
150 ÷ 25 = 6
225 ÷ 25 = 9
the 25 students each get 5 apples, 6 oranges and 9 mangoes
Select the correct answer.
A system of equations and its solution are given below.
System A
x + y = 8
4x - 6y = 2
Solution: (5,3)
Choose the correct option that explains what steps were followed to obtain the system of equations below.
System B
x + y = 8
10x = 50
Answer:
B will be the answer...
Step-by-step explanation:
The second equation in system B is only in terms of y, so we need to use elimination to eliminate the x term from the second equation in system A.
To do that, we need to multiply the first equation by 5.
5 (-x − 2y = 7)
-5x − 10y = 35
Add to the second equation. Notice the x terms cancel out.
(-5x − 10y) + (5x − 6y) = 35 + (-3)
-16y = 32
Combining this new equation with the first equation from system A will get us system B.
-x − 2y = 7
-16y = 32
Answer:
To get system B, the second equation in system A was replaced by the sum of that equation and the first equation multiplied by 6. The solution to system B will be the same as the solution to system A.

Which trig expression can be used to find the height on the tree where the top guy wire attaches if the base of the wire is four feet from the base?
The trigonometric expression that can be used to find the height of the tree where the top guy wire attaches is tan(45 + 30)
How to use trigonometric rations to find height?The height of the tree can be found using trigonometric ratios.
Therefore,
tan ∅ = opposite / adjacent
Hence,
for the higher wire
tan 75 = h / 4
4 tan 75 = h
This can be express as follows:
tan 75 = tan(45 + 30)
Hence,
4 × 3.73205080757 = 14.9282032303 ft = 14.9ft
Hence, the trigonometric expression that can be used to find the height of the tree where the top guy wire attaches is tan(45 + 30)

Let (-7,3) be a point of terminal side of 0
Find Cos Sec Cot
The trigonometry ratios are cos(θ) = -7/√58, sec(θ) = -√58/7 and cot(θ) = -7/3
How to determine the trigonometry ratios?The point on the terminal side is given as:
(x, y) = (-7, 3)
Start by calculating the hypotenuse using:
[tex]h= \sqrt{x^2 + y^2[/tex]
So, we have:
[tex]h= \sqrt{(-7)^2 + 3^2[/tex]
Evaluate
[tex]h= \sqrt{58[/tex]
The cosine is then calculated using:
cos(θ) = x/h
This gives
cos(θ) = -7/√58
The secant is then calculated using:
sec(θ) = 1/cos(θ)
This gives
sec(θ) = -√58/7
The cotangent is then calculated using:
cot(θ) = cos(θ)/sin(θ)
Where
sin(θ) = y/h
So, we have:
sin(θ) = 3/√58
So, we have:
cot(θ) = (-7/√58)/(3/√58)
This gives
cot(θ) = -7/3

It also mentions that the width of Rectangle is 2 ft less than Rug A. The expression could be written as Width = (x-2)

boat traveled downstream a distance of 60 mi and then came right back. If the speed of the current was 6 mph and the total trip took 4 hours find the average speed of the boat relative to the water.
Answer:
7.5mph
Step-by-step explanation:
Let the average speed of the boat to be x mph.
Total Distance = Avg. Speed x Total Time
60 = ((x+6) + (x-6))(4)
60 = (x+6+x-6)(4)
(2x)(4)=60
2x=60/4
2x = 15
x = 15 /2
x = 7.5mph
Answer:
15 +√261 ≈ 31.155 mph
Step-by-step explanation:
The time for the trip can be found by dividing the distance by the speed.
__
setupThe relation between time, speed, and distance is ...
time = distance/speed
The speed for the downstream leg was the sum of the boat speed (b) and 6 mph. The speed for the upstream leg was the difference. So the total trip time was ...
4 = 60/(b +6) +60/(b -6) . . . total time is the sum of the times for the legs
__
solutionMultiplying by the product of the denominators, we have ...
4(b +6)(b -6) = 60(b -6) +60(b +6)
b² -36 = 30b . . . . divide by 4 and simplify
b² -30b = 36 . . . . put in a form useful for completing the square
(b -15)² = 36 +15² . . . . . complete the square
b -15 = √261 . . . . . . . . take the square root (negative root is extraneous)
b = 15 +√261 ≈ 31.155 . . . . add 15
The average speed of the boat was about 31.155 mph.
