21. The odd numbers on a regular die are painted red. On a second regular die, the numbers that are one less than a perfect squa
ivanzaharov [21]

The chance that both come up red is 2/3.

<u>Step-by-step explanation</u>:

First regular die :

The total outcomes are {1,2,3,4,5,6} = 6

Painted red are odd numbers {1,3,5} = 3

Second regular die :

The total outcomes are {1,2,3,4,5,6} = 6

Painted red are one less than perfect square which is 4-1 is {3} = 1

  • Probability (both red) = (red in 1st die / total outcome) + (red in 2nd die / total outcome)

P(both red) = 3/6 + 1/6

⇒ 4/6

⇒ 2/3

The first equation in the system models the heights in feet, h, of a falling baseball as a function of time, t. The second equat
Masja [62]

Answer:

The height of the baseball is 35 feet at the moment the player begins to leap.

Step-by-step explanation:

We are given equations as:

h(t)=35+16t^2--------(1)

Where h represents the heights in feet, h, of a falling baseball as a function of time, t.

The second equation is given as:

h(t)=6+18t-16t^2-------(2)

Where h represents  the heights in feet, h, of the glove of a player leaping up to catch the ball as a function of time, t.

Hence when at the time of leap i.e. at t=0.

first equation i.e. equation (1) yields h(0)=35 i.e. it represents:

"  The height of the baseball is 35 feet at the moment the player begins to leap "

Hence option: C is correct.
