If a die is rolled 36 times, how many times is the number 4 expected to come up?
Snezhnost [94]

Answer: 4/36 or 1/9

Step-by-step explanation: The answer will be 1/9 because when a dice is rolled 6 times, every number has a 1/6 chance of being the number. So if the die is rolled 36 times, the number will show up 1/9 of the time.

It's y-intercept is (0, 5).

It's x-intercepts or roots are (-1, 0) and (5, 0).

It's vertex is (2, 9).

___________________________________

Keep in mind that the y-intercept is when x = 0.

WILL GIVE THANKS, BRAINIEST, AND 5 STARS! PLEASE HELP!
Andrew [12]

Answer:

a = \frac{1}{2} , b = 5, and  \frac{2b}{a} = 20

Step-by-step explanation:

f(x) = - x² + b, x ≤ 0     You would use this equation for f(-2). Since -2 is less than 0.

f(x) = - x² + b, x ≤ 0   ← You can ignore the x ≤ 0 part.

f(-2) = - (-2)² + b         Input the value -2 as x. The question states that f(-2) =1.

1 = - (-2)² + b              So switch f(-2) with 1 on the left side only.

1 = - (4) + b                Simplify. Do the exponents first, so (-2)² = 4.

1 = - 4 + b

<u>+4  +4   </u>                    Do inverse operations

5 = b

Next,

f(x) = 2ax +3, x > 0      You would use his equation for f(2). Since 2 is greater than 0.

f(x) = 2ax +3, x > 0   ← You can ignore the x > 0 part.

f(2) = 2a(2) + 3             Input the value 2 as x.

f(2) = 4a +3           Simplify. The equation states f(2) = 5. So switch f(2) with 5

5 = 4a +3              on the left side only.

<u>-3        - 3</u>                     Do inverse operations

2 = 4a                          

\frac{2}{4} = \frac{4a}{4}                           Divide 4 on both sides to isolate the variable a

\frac{2}{4} = a                            Simplify

\frac{1}{2} = a

Then,

The second part says to find \frac{2b}{a}

\frac{2b}{a}

\frac{2(5)}{(\frac{1}{2}) }                  Input both the values of a and b

\frac{10}{\frac{1}{2} }                    Simplify

20.

The answer for a is \frac{1}{2}, the answer for b is 5, and the answer for \frac{2b}{a} is 20.

Mazyrski [523]

Answer:

Winner got 3920

Loser got 1470

Step-by-step explanation:

8 + 3 = 11
