If a person who is 5. 5 feet tall throws a baseball into the air, the path can be modeled using the table of values, where x represents the time in seconds and y is the height of the ball in feet.
x y
0 5. 5
1 7. 35
2 8. 9
3 10. 15
4 11. 1
5 11. 75
Which quadratic equation models the data in the table?
y= −0. 25x2 + 2x + 5. 5
y= −0. 35x2 + 2x + 5. 5
y= −0. 27x2 + 3x + 5. 5
y= −0. 15x2 + 2x + 5. 5
The data in the table is an illustration of a quadratic equation, and the quadratic equation that models the data is (d) y = -0.15x² + 2x + 5.5
How to determine the quadratic model?A quadratic model is represented as:
y = ax² + bx + c
Using the point (x,y) = (0,5.5);
We have:
a(0)² + b(0) + c = 5.5
This gives
c = 5.5
Substitute c = 5.5 in y = ax² + bx + c
y = ax² + bx + 5.5
Using the point (x,y) = (1,7.35);
We have:
a(1)² + b(1) + 5.5 = 7.35
This gives
a + b + 5.5 = 7.35
Subtract 5.5 from both sides
a + b = 1.85
Using the point (x,y) = (2, 8.9);
We have:
a(2)² + b(2) + 5.5 = 8.9
This gives
4a + 2b + 5.5 = 8.9
Subtract 5.5 from both sides
4a + 2b = 3.4
Divide through by 2
2a + b = 1.7
Subtract a + b = 1.85 from 2a + b = 1.7
2a - a + b - b = 1.7 - 1.85
This gives
a = -0.15
Substitute a = -0.15 in 2a + b = 1.7
-2 * 0.15 + b = 1.7
This gives
-0.3 + b = 1.7
Add 0.3 to both sides
b = 2
Substitute a = -0.15 and b = 2 in y = ax² + bx + 5.5
y = -0.15x² + 2x + 5.5
Hence, the quadratic equation that models the data in the table is (d) y = -0.15x² + 2x + 5.5

Which best describes the resulting three-dimensional figure? a cone with a base radius of 26 cm a cone with a base radius of 14 cm a cylinder with a base radius of 26 cm a cylinder with a base radius of 14 cm
The best description of the resulting three-dimensional figure when the considered figure is revolved is: A cylinder with height 24 cm.
What is solid of revolution?When a figure is revolved around some fixed axis, the whole three dimensional solid formed from the area that it swaps out is called solid of revolution.
Since no image is specified, we will work on the image attached below.
We can visualize and imagine that the horizontal line is still and just rotating on its place. The rectangle will revolve around, and therefore will swap out a cylindrical shape.
Since the length of the rectangle is 24 cm, and it is rotated on its length, so that will serve as height of the formed cylinder.
Thus, the best description of the resulting three-dimensional figure when the considered figure is revolved is: A cylinder with height 24 cm.

Trees that are cut down and stripped of their branches for timber are
approximately cylindrical. A timber company specializes in a certain type
of tree that has a typical diameter of 50 cm and a typical height of about
10 meters. The density of the wood is 380 kilograms per cubic meter, and
the wood can be sold by mass at a rate of $4. 75 per kilogram. Determine
and state the minimum number of whole trees that must be sold to raise
at least $75,000. *
From the calculations, the number of whole trees that can be sold at $75,000 is 21 trees.
What is density?Density is defined a the mass per unit volume. Now we have the following;
Diameter = 50 cm or 0.5 m
height = 10 meters
volume = ?
Density of the cylinder = 380 Kg/m^3
Now;
We can get the volume from;
V = πr^2h
V = 3.142 * (0.5/2)^2 * 10
V = 1.96m^3
From;
D = m/V
m = DV
m = 1.96m^3 * 380 Kg/m^3
m = 744.8 Kg
If 1 Kg of wood is sold at $4. 75
744.8 Kg is sold at 744.8 Kg * $4. 75/ 1 Kg
= $3537.8
Number of whole trees to be sold at $75,000= $75,000/$3537.8
= 21 trees

The frequency table shows the ages of the actors
in a youth theater group. What percent of the
actors are 10 to 12 years old?
The percentage of youth that are category 10 to 12 is the quotient of their frequency to the total frequency
55% of the actors are 10 to 12 years old
How to determine the percentage?From the complete question, we have the following parameters
Age 10 - 12 = 22 youthsTotal youth = 40The percentage of youth in the age category 10 - 12 is then calculated as:
Percentage = Frequency of age category 10 - 12/Total frequency
This gives
Percentage = 22/40
Evaluate the quotient
Percentage = 55%
Hence, 55% of the actors are 10 to 12 years old

The experimental probability is the same as the theoretical probability.
The experimental probability is 4% lower than the theoretical probability.
The experimental probability is 4% higher than the theoretical probability.
The experimental probability cannot be concluded from the data in the table.
Answer: Answer: Third option is correct.
Step-by-step explanation: Step-by-step explanation:
Since we have given that
Number of heads = 56
Number of tails = 44
Total number of flips = 100
So, Probability of getting head is given by
Theoretical probability of getting head is given by
There is a difference of
0.54-0.50=0.04 = 4%
Hence, the experimental probability is 4% higher than the theoretical probability.
Therefore, Third option is correct.
