A chair can be purchased in one of four colors: red, white, green, or blue. The number of chairs purchased in each color is listed below. Red: 150 white: 450 green: 225 blue: 375 Based on the information shown in the list, what is the probability that the next chair purchased will be red?
Answers
Answer:
[tex]P(Red) = 0.125[/tex]
Step-by-step explanation:
Given
[tex]Red: 150[/tex]
[tex]White: 450[/tex]
[tex]Green: 225[/tex]
[tex]Blue: 375[/tex]
Required
Determine the probability of getting a red chair, next.
First, we nee the total number of chairs
[tex]Total = 150 + 450 + 225 + 375[/tex]
[tex]Total = 1200[/tex]
Probability of getting red is then calculated as thus;
[tex]P(Red) = Red/Total[/tex]
[tex]P(Red) = 150/1200[/tex]
[tex]P(Red) = 0.125[/tex]

A seat on a Ferris wheel is level with the center of the wheel. The diameter of the wheel is 200 feet. Suppose the wheel rotates 60°, causing the height of the seat to decrease. How much closer to the ground is the seat after the is to be determined.
What are trigonometric equations?
These are the equation that contains trigonometric operators such as sin, cos.. etc.. In algebraic operation.
Diameter = 200
Radius = Diameter/2 = 100
Rotational angle = 60°
Let the height be h
tan60 = h/100
√3 = h/100
100√3 = h
Thus, the required height of the seat from the ground is 100√3. Option D is correct.

Using the figure below, find the measure of z ( just enter in the number for your answer don’t worry about the degree symbol or saying “ degrees” after the number
Answers
Answer:
z = 29°
Step-by-step explanation:
We know that the 3 angles in a triangle always add up to 180°. So for triangle ABC, angle A = 59° (given), and angle B = 43° + 49° = 92° (given).
angle A + angle B + angle C = 180°
59° + 92° + z = 180°
151° + z = 180°
Subtract 151° from both sides of the equation
z = 180° -151°
z = 29°

Alex has twice as much money as Jennifer. Jennifer has $6 less than Shannon. Together they have $54. How much money does each have?
Answers
Answer:
Alex has twice as much money as Jennifer.
a = 2j
Jennifer has $6 less than Shannon.
j = s-6
j+6 = s
All together the three friends have $54.
a + j + s = 54
Replace a and s
2j + j + (j+6) = 54
4j = 54 - 6
4j = 48
j = 48/4
j = 12
Jennifer has $12
Alex= 2*12 = $24
Shannon = 24+12+s = 54
= 36+s = 54
s = 18
Shannon has $18

O ZORP and ZORN are a linear pair
O ZORP and ZORN are vertical angles
O 80 = 3x +10
O x = 30
Answers
(a) ∠ORP and ∠ORN are a linear pair .
Let us prove that option a , is the correct option by finding the value of x .
Angle ORP and angle ORN are a linear , which means their sum will be equal to 180° .
So :-
[tex]80 + 3x + 10 = 180[/tex]
[tex]3x + 80 + 10 = 180[/tex]
[tex]3x + 90 = 180[/tex]
[tex]3x = 180 - 90[/tex]
[tex]3x = 90[/tex]
[tex]x = \frac{90}{3} [/tex]
[tex]x = 30°[/tex]
As we were able to find put the value of x only after we cam to know that ∠ORP and ∠ORN are a linear pair , we say that option a is the correct statement .
Therefore , the correct answer is :-
(a) ∠ORP and ∠ORN are a linear pair .
The value of x is equal to 30°. Hence, proved.
What are angles at a point on a straight line?
Angles on a straight line relate to the sum of angles that can be arranged together so that they form a straight line. Angles on a straight line add to 180°.
Given that, m∠ORP=80° and m∠ORN=(3x+10)°.
Here, m∠ORP+m∠ORN=180° (Angles on straight line adds upto 180°)
80°+(3x+10)°=180°
90°+3x=180°
3x=90°
x=90°/3
x=30°
Hence, proved.

Jamila is walking her small dog for a walk around her neighborhood. They travel 3/5 They travel 3/5of a mile in 40 minutes. Determine the unit rate they walk in minutes per hour.
Answers
Answer:
unit rate = 0.9 miles per hour
Step-by-step explanation:
Rate per hour of walking is calculate by = distance moved in miles/ time taken in miles
_________________________
given
distance = 3/5 of a mile = 3/5 miles
time = 40 minutes
we have to find time in hours
60 minutes = 1 hour
40 minutes = 1/60 *40 hours = 2/3 hours
thus
unit rate = (3/5 miles)/ (2/3 hours ) = (3*3)miles/(5*2) hour = 9/10 miles per hour
unit rate = 0.9 miles per hour
