Which of the following discrete random variables could be represented by a
probability histogram whose bars are all the same height?
O A. The number of goals scored per game by a soccer team in one
season
B. The ages of students in a high school
O C. The outcomes of spinning a spinner with five equal sections
O D. The outcomes of rolling a weighted die
Answer: The outcome of spinning a spinner with five equal outcomes
Step-by-step explanation:
The discrete random variable that could be represented by a probability histogram whose bars are all the same height is;
Option C; The outcomes of spinning a spinner with five equal sections
The probability histogram is a type of histogram whereby the height of each bar shows the true probability of each outcome of a specific number of trials.
Now, let us look at the options;
Option A; This cannot be represented by a probability histogram because it doesn't show probability.
Option B; This cannot be represented by a probability histogram because it shows just ages and doesn't show probability.
Option C; This can be be represented by a probability histogram because it shows the probability of each outcome of spinning five equal sections.
Option D; This cannot be represented by a probability histogram because it should show the probability of each outcome and not just that of one weighted die.

The length of a new rectangular playing field is 6 yards longer than double the width. If the perimeter of the rectangular playing field
is 312 yards, what are its dimensions?
The width is yards
Answer:
Width of field = 50 yards
Length of Yards = 106 yards
Step-by-step explanation:
Let the width of field be x yards
given that "The length of a new rectangular playing field is 6 yards longer than double the width"
Length of Yards= 2*width of field + 6 = 2x+6 yards
perimeter of the rectangular playing field = 312 yards
We know that perimeter of rectangle is given by 2(length + width ).
Since field is rectangular then
2(length + width ) = 312
2(x+2x+6) = 312
=> 3x+6 = 312/2 = 156
=> 3x = 156 - 6 = 150
=> x = 150/3 = 50
Thus,
Width of field is x = 50 yards
Length of Yards= 2x+6 yards = 2*50+6 yards = 106 yards
A new car is purchased for 15700 dollars. The value of the car depreciates at 7.5% per year. To the nearest year, how long will it be until the value of the car is 10100 dollars?
Answer:
10100=15700(1-0.075)^x
10100=15700(0.925)^x
divide both sides by 15700
0.925^x=101/157
convert decimal
(37/40)^x=101/157
take the log
x= log 37/40 (101/157)
x= 5.65824
It will take almost 6 years to depreciate the value of the car to 10100 dollars.
Express in numbers six and three hundredths
Answer:
6.03
Step-by-step explanation:
'6' would be a whole number. When stating decimals, you would say the whole numbers before 'and'.
For example: 5.6 would be 'five and six tenths'. Note that five is before 'and'.
'Three hundredths' would be .03.
Therefore:
"Six and three hundredths" would be '6.03'.

Point D is an interior of ABC. what is m DBC can u help me pls
Answer:
36.5 degrees
Step-by-step explanation:
angle abc is a straight angle ( which is 180 degrees )therefore:
angle ABD + angle DBC = angle ABC
substituting the given measurements gives us=
3x + 22 + x - 4 = 180
4x = 162
x = 40.5
the question asks us to find measure of angle DBC so we substitute x which =
measure DBC = x - 4
measure DBC = 40.5 - 4
measure DBC = 36.5 degrees

A balloon rises vertically at the rate
of 10 ft. per second. If it encounters
a wind that gives a horizontal displace-
ment of 5 feet per second,
find (to the nearest whole degree)
the angle with the horizontal at
which the balloon rises.
a.
b.
find (to the nearest 10 feet) its
distance from the starting point
after one minute.
Answer:
a) 63°
b) 600ft
Step-by-step explanation:
To solve the above question, we would be using Trigonometric function
a) Find (to the nearest whole degree)
the angle with the horizontal at
which the balloon rises.
This above question a is a right angled triangle that is solved for using Trigonometric function of tan
From the question, we told that,
Vertical distance ( opposite side) = 10 feet
Horizontal distance ( adjacent side) = 5 feet.
Tan θ = opposite side/ adjacent side
Tan θ = 10/5
Tan θ = 2
θ = arc tan (2) or tan -¹(2)
θ = 63.434948823°
θ = 63°
The angle with the horizontal at
which the balloon rises to the nearest whole degree is 63°
b) find (to the nearest 10 feet) its
distance from the starting point
after one minute.
Distance = Speed × time
Time is given in the question as 1 minute
We would convert it to seconds = 60 seconds
We are told in the question that the balloon rises vertically at the speed of 10ft/s
Distance = 10ft/s × 60seconds
Distance from the starting point per minute = 600ft
The object below is made of solid plastic. It is a cylinder with an indentation at the top
in the shape of a cone.
What is the volume to the nearest tenth of a cubic inch, of the plastic object?
Answer: 97.6 in3
Step-by-step explanation:
Hi, to answer this question we have to calculate the volume of the cylinder and subtract the volume of the cone:
Volume of a cylinder: π (diameter /2) ^2 (height)
Vcy = π (4 /2) ^2 (8) = π (2) ^2 (8) =100.5 in3
Volume of a cone = 1/3 π (diameter /2) ^2 (height)
V Co = 1/3 π (4/2) ^2 (0.7) = 1/3 π (2) ^2 (0.7) = 2.9 in3
Finally:
Volume of the cylinder - volume of the cone = 100.5-2.9 = 97.6 in3

Jimmy is incorrect.
Using long division, you can find that the real answer.
First, subtract [tex]x^2(x-2)[/tex] from the original expression, leaving you with [tex]9x^2+2x-40[/tex].
Next, subtract [tex]9x(x-2)[/tex] from the expression, leaving you with [tex]20x-40[/tex]. Finally, subtract [tex]20(x-2)[/tex] from the expression, leaving you with a remainder of 0. This means that the real quotient is [tex]x^2+9x+20[/tex]. Hope this helps!
