Answer:

The last table is the one that represents a function

Step-by-step explanation:

To be a function you can't have two different y values for the same x.

In option one, for x =2, we have two values for y: y = 2 and y = -2. So this is not a function.

In option two something similar happens, for x = 5 we have two different y values: y = 2 and y = 8, this is also not a funcion.

In option three for x = 3 we also have two different values of y: y = 4 and y = 5, this is not a function.

The correct option is the fourth:

In option four, <u>for every </u>x<u> we have a different value of </u>y and we don't have two y's for the same x (like in the other options)

Mazyrski [523]

Answer:

The number of viewers Network A expects will watch their show is 1.4 million viewers.

Step-by-step explanation:

The expected value is calculated by multiplying the possible outcomes by the probability of their occurrence and adding the results

Therefore, we have the expected value given by the following expression;

Estimated network A viewers  where network B schedule top show = 1.1 million viewers

Estimated network A viewers where network B schedule a different show = 1.6 million viewers

Probability that Network B will air its top show = 0.4

Probability that Network B will air another show = 0.6

We therefore have;

Expected value, E of Network A viewers is therefore;

E = 1.1 × 0.4 + 1.6 × 0.6 =  0.44 + 0.96 = 1.4 million viewers.

Network A expects 1.4 million viewers will watch their show.

What is the Anwser if a divide 33 into 2 groups so the ratio is 4 to 7
Naddika [18.5K]
You have to solve this algebraicly.
To do this set up the proportion and add x to each term.
You get 4x and 7x
Set this equal to 33
4x+7x=33
Combine like terms and get 11x=33
Divide by 11
x=3
Now go back to 4x and 7x
Multiply them by x and get 12(4×3=12) and 21(7×3=21)
One group is 12 and the other is 21.
