Answer:
It is desirable to have finish time with low percentile.
Step-by-step explanation:
It is more desirable to have a low percentile for finish time for runners when running a race. A low percentile means a short time, which is faster.
When competing in a race, a low percentile finish time is preferable.
What is the relationship between speed and time?
Speed is the rate at which a distance changes over time. So speed and time are inversely proportional.
In a race, the person who runs faster will finish the race first. So a faster run takes less time.
Hence, it is more desirable to have a low percentile finish time during a race.

Two dice are tossed and the magnitude of the difference in the number of dots facing up in the two dice is noted. (a) What is the sample space of the event of tossing of the two dice
Answer:
Sample space S = {0,1,2,3,4,5}
Step-by-step explanation:
We all know that when a dice is tossed, the minimum value that can be obtained is 1 and the maximum value that can be obtained is 6.
Now, when two dice are tossed, the possible cases are:
[tex]= \left\{\begin{array}{cccccc}(1,1)&(1,2)&(1,3) &(1,4)&(1,5)&(1,6)\\(2,1)&(2,2)&(2,3) &(2,4)&(2,5)&(2,6)\\(3,1)&(3,2)&(3,3) &(3,4)&(3,5)&(3,6)\\(4,1)&(4,2)&(4,3) &(4,4)&(4,5)&(4,6)\\(5,1)&(5,2)&(5,3) &(5,4)&(5,5)&(5,6)\\(6,1)&(6,2)&(6,3) &(6,4)&(6,5)&(6,6)\end{array}\right\}[/tex]
However, the magnitude of the difference in no. of dots showing up in the two dice is:
[tex]= = \left\{\begin{array}{cccccc}(1,1)=0&(1,2)=1&(1,3)=2 &(1,4)=3&(1,5)=4&(1,6)=5\\(2,1)=1&(2,2)=0&(2,3)=1 &(2,4)=2&(2,5)=3&(2,6)=4\\(3,1)=2&(3,2)=1&(3,3)=0 &(3,4)=1&(3,5)=2&(3,6)=3\\(4,1)=3&(4,2)=2&(4,3)=1 &(4,4)=0&(4,5)=1&(4,6)=2\\(5,1)=4&(5,2)=3&(5,3)=2 &(5,4)=1&(5,5)=0&(5,6)=1\\(6,1)=5&(6,2)=4&(6,3)=3 &(6,4)=2&(6,5)=4&(6,6)=0\end{array}\right\}[/tex]
Thus, the sample space Sample space-related when two dice are tossed & the magnitude is:
S = {0,1,2,3,4,5,}

Answer:
I think it's B (A and C)
Step-by-step explanation:
1. The height of a soccer ball that is kicked from the ground can be approximated by the function:
y= -18x^2 + 90x
where y is the height of the soccer ball is x seconds after it is kicked.
Find the time, in seconds, it takes from the moment the soccer ball is kicked until it returns to the ground.
2. The height of a soccer ball that is kicked from the ground can be approximated by the function:
y = -16x^2 + 64x
where y is the height of the soccer ball in feet x seconds after it is kicked. What is the soccer ball's maximum height in feet?
Answer:
2. [tex]\displaystyle 64\:feet[/tex]
1. [tex]\displaystyle 5\:seconds[/tex]
Step-by-step explanation:
2. Sinse we do not have a y-intercept [C-value in this case], we have to use a part of the quadratic formula to solve for x, and rewrite this equation in Vertex Form, with [tex]\displaystyle [h, k][/tex] as the vertex point. Observe:
[tex]\displaystyle -\frac{b}{2a} = x \\ \\ -\frac{64}{2[-16]} = \frac{-64}{-32} = 2[/tex]
Now, keep in mind that [tex]\displaystyle -h[/tex] in the vertex formula, [tex]\displaystyle y = a[x - h]^2 + k,[/tex] gives you the OPPOSITE TERMS OF WHAT THEY REALLY ARE, so in this case, sinse 2 is already positive, you do not need to alter its operation sign. With this being stated, you should already have this:
[tex]\displaystyle y = -16[x - 2]^2[/tex]
Now, to find k, all you have to do is plug 2 into the TOP equation to get your maximum height:
[tex]\displaystyle -16[2]^2 + 64[2] = -16[4] + 128 = -64 + 128 = 64 \\ \\ \\ y = -16[x - 2]^2 + 64[/tex]
Therefore, sinse 64 is your k-value, 64 feet is indeed your maximum height.
1. Simply factour the quadratic equation:
[tex]\displaystyle y = -18x^2 + 90x \\ 0 = -18x[x - 5] \\ \\ 5, 0 = x[/tex]
In this case, from a height of sixty-four feet, it is IMPOSSIBLE for the football to hit the ground in zero seconds, therefore the ball will reach the ground in 5 seconds, which makes alot more sence.
I am joyous to assist you at any time.

Please help
See the picture
Test
Please i need
Answer:
100.3 units²
Step-by-step explanation:
Area of the figure = area of two semicircles + area of a parallelogram
= 2(½*πr²) + b*h
Where,
Radius (r) = ½ of 8 = 4
Base (b) = 10
Height (h) = 5
Plug in the values
Area of figure = 2(½*π*4²) + 10*5
= 16π + 50
Area = 100.265482
Area of figure = 100.3 units² (nearest tenth)

The 150 students in the band will attend an awards assembly. A random survey of 30 was done to see what type of pizza they would order. 10 Pepperoni 15 Cheese • 5 Hamburger Based on the survey results, which of these is the best prediction of the types of pizza wanted by the 150 students? A. There are 40 students who want pepperoni B. There are 100 students who want either pepperoni or hamburger C. There are 10 more students who will want cheese than hamburger D. There are 5 more students would want pepperoni than hamburger (PLEASE ANSWER ILL GIVE BRAINLIEST)
Answer:
None are correct.
Step-by-step explanation:
10/30 wanted pepperoni, so 1/3 of them wanted pepperoni.
15/30 wanted cheese, so 1/2 wanted cheese.
5/30 wanted hamburgers, so 1/6 wanted hamburgers.
You can use this information to estimate the number of the 150 students who wanted each.
1/3 of 150 = an estimated 50 wants pepperoni
1/2 of 150 = an estimated 75 wants cheese
1/6 of 150 = an estimated 25 wants hamburgers
Now you can use this to see which one is true.
A. There are 40 students who want pepperoni
not true, there are 50
B. There are 100 students who want either pepperoni or hamburger
50(pepperoni) + 25(hamburger) = 75, so this is not true
C. There are 10 more students who will want cheese than hamburger
75(cheese) - 25 (hamburger) = 50, so this is not true.
D. There are 5 more students would want pepperoni than hamburger
50 (pepperoni) - 25 (hamburger) = 25, so this is not true
None of these answers are correct
How do you find the area of a triangle ?
Answer:
to find the Area of a Triangle, you have to multiply the base times the height of the triangle to find the Area.
Step-by-step explanation:
For example..
If the Base ( bottom part of the triangle) was 10 and the height ( the vertical line of the triangle) was 5, you would multiply them together to get 50. So 5o would be the area of the Triangle.

The diameter of Joseph's bicycle wheel is 20 inches Which is the circumference to the nearest inch?use 3.14 for Π
Answer:
63 inches
Step-by-step explanation:
the diameter is the entire line across the circle, the things needed to find out the circumference of the circle are the radius. that means you would divide your diameter in half to get 10. after you done that, you would input that into the equation:
c=2Π10
that would get you about 62.83 or 63
