Option C is correct
The ratio of green to red marbles is, 3 : 1
Step-by-step explanation:
As per the statement:
A bag contains 44 marbles, some red and some green.
⇒Total marbles = 44
If there are 11 red marbles.
then;
Green marbles = Total marbles - red marbles.
Substitute the given values we have;
Green marbles = 44 - 11 = 33
We have to find the ratio of green to red marbles.
Therefore, the ratio of green to red marbles is, 3 : 1
The equation for the path of the ball can be measured using a regression model calculator which produced the quadratic model ;
- y(x) = - 16x² + 36x + 4
- Height at x = 1.7 = 18.89 feets
<u>The table given</u> :
Time, x : __0.5 ___ 1 ____ 1.5 ____ 2
Height, y _ 18 ____22 ___ 24 ____ 12
<u>Using </u><u>technology</u><u> such as a </u><u>quadratic regression</u><u> calculator or </u><u>excel</u> ;
The quadratic regression model obtained is :
- y(x) = - 16x² + 36x + 4
<u>The </u><u>height after, 1.7 seconds</u><u>, x = 1.7 can be calculated thus</u> :
Put x = 1.7 in the equation :
- y(1.7) = - 16(1.7)² + 36(1.7) + 4
- y = 18.89 feets
Therefore, the height of the baseball after 1.7 seconds will be 18.89 feets.
