What are the range values of the function f (x ) = 3x + 4 for the domain values {-5, -1, 0, 2, 7}?
Airida [17]

Answer:

Range values are:

{-11, 1, 4, 10, 25}

Step-by-step explanation:

Domain values are the possible x values that can be entered into the function, or the inputs.  Range values are the y values, or the outputs. By inserting every value in the set into the function, we get the outputs (y values)

-15 + 4 = -11

-3+4 = 1

0 + 4 = 4

6 + 4 = 10

21 + 4 = 25

Remember to put them in order.

Kipish [7]

Answer:

<em>The probability of scoring two goals in both times is</em><em> 0.137 or 13.7%</em>

Step-by-step explanation:

Statistics show that a certain soccer player has a 63% chance of missing the goal each time he shoots.

So P(A)=0.63

Hence, the probability of getting success in his shoots will be,

P(A^c)=1-P(A)=1-0.63=0.37

The probability of scoring two goals in both times is,

=P(A^c)\cdot P(A^c)

=0.37\times 0.37

=0.137

=13.7\%

How many movies are 120 minutes or less in length?
borishaifa [10]

The movies of 120 min or less than 120 mins are 100

Further explanation:

A histogram is a visual representation of data.

In the given histogram we can see that

5 movies are 0 to 30 minutes, 10 movies are 31 to 60 minutes, 30 movies are 61 to 90 minutes, 55 movies are 91 to 120 minutes, and 15 movies are over 120 minutes.

In order to find the number of movies which are 120 minutes long or less than 120 minutes we will add up all the number of movies with 120 length and less than that

So,

No.\ of\ movies\ 120\ min\ long\ or\ less\ than\ that = 5+10+30+55\\=100\ movies

The movies of 120 min or less than 120 mins are 100

3x^{3} +15x^{2} +18x\\3x(x^{2} +5x+6)\\3x(x-1)(x+6)

So, there you go!

sorry if this did not make sense...

What I did was essentially factor out 3x first, and then factor the second product by grouping.

Hope this Helps!
