State whether the data described below are discrete or continuous, and explain why. The maximum capacities of various stadiums

Andreyy89

Answer:

Step-by-step explanation:

When a data is continuous, the values it can take are the real numbers, this means it can take any value in an interval.

When a data is discrete, the values can take only certain values in an interval, this data usually refers to natural numbers.

In the case of the maximum capacities of various stadiums it is clear that their capacities can only be found in the natural numbers (a stadium cannot have a capacity of 4647576.56 people or any number with a decimal). Therefore, the data are discrete because it can take only some specific values.

Thus, the correct answer is C.

A and B are independent events. P(A) = 0.40 and P(B) = 0.20. What is PA and B)?

solmaris [256]

Answer:

The value of P( A and B ) is 0.08.

Step-by-step explanation:

When two events are independent then the probability of both occurring is equal to the product of probabilities of both events individually,

That is, If X and Y are independent events,

Then, P(X∩Y) = P(X) × P(Y),

or P(X and Y) = P(X) × P(Y),

Here, P(A) = 0.40 and P(B) = 0.20,

Hence, P(A∩B) = P(A) × P(B)

= 0.40 × 0.20

= 0.08

System of equations 9x+8y=-19 ; 7x+9y=-12

klasskru [66]

Answer:

(-3,1)

Step-by-step explanation:

9x+8y=-19

7x+9y=-12

I'll assume the question is to find the solution to these equations. The solution will be the point (x,y) where the two lines intersect. The intersection is the one point that satisfies both equations (the smae value of (x,y) works in both.

We can either solve matematically of graph to find the intersection. I'll do both, and hope the answers are identical.

Matematically

Rearrange either equation to isolate one of the variables (either x or y). I'll take the second and isolate x:

7x+9y=-12

7x = -9y - 12

x = (-9y - 12)/7

Now use this definition of x in the other equation:

9x+8y=-19

9((-9y - 12)/7) + 8y = -19

(-81y - 108)/7 + 8y = -19

-81y - 108 + 56y = - 133

-25y = -25

y = 1

If y = 1, then:

9x+8y=-19

9x+8(1)=-19

9x = -27

x = -3

The solution is (-3,1)

Graphing

Graph both lines and look for the intersection. The attached graph shows the lines cross at (-3,1).

The solution, bu both approachjes, is (-3,1)
