There is a sample of 500 and the population proportion is 0.47. What is the probability that the proportion is greater then 0.50
Answers
Answer: 0.0895
Step-by-step explanation:
Let p= population proportion.
Given : Sample size : n= 500
p= 0.47
Required probability = [tex]P(\ha{p}>0.50)[/tex]
[tex]=P(\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}>\dfrac{0.50-0.47}{\sqrt{\dfrac{0.47(1-0.47)}{500}}}) \\\\=P(z>1.344)\ \ \ [z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}]\\\\=1-P(z<1.344)\\\\=1-0.9105\approx0.0895[/tex]
Hence, required probability = 0.0895
An elevator in a mine shaft is stopped at a .25 feet below ground level. And then travels 28 feet downward. What equation can be written to find the final position in feet of the elevator in relations to ground level?
Answers
Correct question:
An elevator in a mine shaft is stopped at 25 feet below ground level. And then travels 28 feet downward. What equation can be written to find the final position in feet of the elevator in relations to ground level?
Answer:
-53 feets
Step-by-step explanation:
Initial stop point = 25 feets below ground level
Further distance traveled = 28 feets below ground level
Final position in feet = Initial stop point + further distance traveled
Note : distances or point traveled below ground level or downward is represented as negative.
Final position in feets = (-25)feets + (-28)feets
Final position in feets = - 53 feets

Zachary and his children went into a grocery store and will buy bananas and peaches.
Each banana costs $0.50 and each peach costs $1.50. Zachary has a total of $8 to
spend on bananas and peaches. Write an inequality that would represent the possible
values for the number of bananas purchased, b, and the number of peaches
purchased, p.
Answers
Answer:
0.5b + 1.5p ≤ 8
Step-by-step explanation:
The inequality function is as follows:
Let us assume the number of bananas acquired be b
And, the number of peaches acquired be p
Cost of each banana be $0.50
ANd, the cost of each peach be $1.50
Also the total would be $8
The possible values of banana is 0.5b
And, for peaches it would be 1.5p
So, the inequality function is
0.5b + 1.5p ≤ 8
Answer:
0.5b + 1.5p ≤ 8

What is the difference between (-10)² & -10²? What are the values for each expression?
Answers
Answer:
(-10)² = 100
-10² = -100
Difference = 200
Step-by-step explanation:
For the individual expressions;
(-10)² = -10 * -10
(-10)² = +100
For -10²
-10² = -(10*10)
-10² = -100
Taking the difference;
(-10)² - (-10²) = 100 - (-100)
(-10)² - (-10²) = 100 + 100
(-10)² - (-10²) = 200
Hence the difference is 200

Safe wheelchair ramp specifications require about 4.75° maximum angle to be constructed with the ground. At a particular building, the owner is installing a wheelchair ramp that needs to rise 1 feet off the ground. The owner insists on constructing the angle with the ground at 3°. How much horizontal distance will the ramp cover with these specifications?
Answers
Answer:
The ramp must cover a horizontal distance of approximately 19.081 feet.
Step-by-step explanation:
Given the vertical distance ([tex]y[/tex]), measured in feet, and the angle of the wheelchair ramp ([tex]\theta[/tex]), measured in sexagesimal degrees. The horizontal distance needed for the ramp ([tex]x[/tex]), measured in feet, is estimated by the following trigonometrical expression:
[tex]x = \frac{y}{\tan \theta}[/tex] (1)
If we know that [tex]y = 1\,ft[/tex] and [tex]\theta = 3^{\circ}[/tex], then the horizontal distance covered by this ramp is:
[tex]x = \frac{1\,ft}{\tan 3^{\circ}}[/tex]
[tex]x \approx 19.081\,ft[/tex]
The ramp must cover a horizontal distance of approximately 19.081 feet.
If a line has a slope of 9/5. If one of the points on the line is (-10, -16), which could be another point?
Answers
Answer:
(–5, –7)
Step-by-step explanation:
From the question given above, the following data were obtained:
Slope = 9/5
Coordinate 1 = (–10, –16)
x₁ = –10
y₁ = –16
Coordinate 2 = (x₂, y₂)
Next, we shall determine the change in x and y coordinate. This can be obtained as follow:
Slope = change in y–coordinate / change in x–coordinate
Slope = Δy / Δx
Slope = 9/5
9/5 = Δy / Δx
Thus,
Δy = 9
Δx = 5
Next, we shall determine the second coordinates as follow:
Δy = y₂ – y₁
Δx = x₂ – x₁
For x–coordinate:
x₁ = –10
Δx = 5
Δx = x₂ – x₁
5 = x₂ – (–10)
5 = x₂ + 10
Collect like terms
x₂ = 5 – 10
x₂ = – 5
For y–coordinate:
y₁ = –16
Δy = 9
Δy = y₂ – y₁
9 = y₂ – (–16)
9 = y₂ + 16
Collect like terms
y₂ = 9 – 16
y₂ = – 7
Coordinate 2 = (x₂, y₂)
Coordinate 2 = (–5, –7)
