Answer:

X = 0 , P(0) = 1/3

X = 1 , P(1) = 8/15

X = 2 , P(2) = 2/15

Step-by-step explanation:

Let X be the no. of trucks

X = 0 , P(0) = 6/10 × 5/9 = 1/3

X = 1 , P(1) = 2(6/10 × 4/9) = 8/15

X = 2 , P(2) = 4/10 × 3/9 = 2/15

Answer:

26.376 because the circumference formula is 2*3.14*radius so the radius of the goal would be 9 because radius is half of diameter which is 18 so 2*3.14*9=56.52 and the basketball's radius would be 4.8 and then 2*3.14*4.8 is 30.144 so the answer is 26.376 hope it helps

The distance travelled is 10 m

The velocity gained at the end of the time is 2 m/s

<h3>Motion</h3>

From the question, we are to determine distance travelled and the velocity gained

From one of the equations of motion for <u>linear motion</u>, we have that

S = ut + 1/2at²

Where S is the distance

u is the initial velocity

t is the time taken

and a is the acceleration

First, we will calculate the acceleration

Using the formula,

F = ma

Where F is the force

m is the mass

and a is the acceleration

∴ a = F/m

Where F is the force

and a is the acceleration

From the given information,

F = 50 N

m = 250 kg

Putting the parameters into the equation,

a =  50/250

a = 0.2 m/s²

Thus,

From the information,

u = 0 m/s (Since the object was initially at rest)

t = 10 s

S = 0(t) + 1/2(0.2)(10)²

S = 10 m

Hence, the distance travelled is 10 m

For the velocity

Using the formula,

v = u + at

Where v is the velocity

v = 0 + 0.2×10

v = 2 m/s

Hence, the velocity gained at the end of the time is 2 m/s

Is the number of points scored during a basketball game a discrete random​ variable, a continuous random​ variable, or not a ran
monitta

Answer: Option (B) is correct.

Step-by-step explanation:

The number of points scored during a basketball game is a discrete random variable.

Discrete Random variable:

A discrete random variable is a variable whose value can be evaluated by counting. It is also referred as a countable and finite values. Examples of discrete random variable are as follows:

-The quantity of runs scored during a ball game  

- Number of hits a site gets during seven days  

- Number of lights that wear out in the following year in a stay with 13 bulbs  

- Number of pigeons in a city  

- Number of free-toss endeavors before the principal shot is missed
