Answer:

Winning probability is \frac{1}{3}

Step-by-step explanation:

Favourable outcomes to win are 3 and 6.

Total outcomes are six in fair dice.

So , probability of winning some money =\frac{2}{6}=\frac{1}{3}

To win $20*3 or $20*6 favourable outcome is 1 (3 and 6 respectively)

Thus probability =\frac{1}{6}

Solve for each variable.
dem82 [27]

Answer:

a = 38⁰

b = 54⁰

c = 54⁰

Step-by-step explanation:

a + 142⁰ = 180⁰ because a straight line = 180⁰

b + 38⁰ + 88⁰ = 180⁰ because the angles of a triangle equal 180⁰, and the missing measurement = 38⁰ because it is a vertical angle to angle a

c + 88⁰ = 142⁰ because the angles are corresponding angles

TRUE OR FALSE: FOR ANY FUNCTION, X=F^-1(Y), THEN Y=F(X). PLEASE EXPLAIN
Vesnalui [34]

Answer:

True.

Step-by-step explanation:

For example let f(x) = 3x + 1  then f-1(x)  is found as follows

Let f(x) = y = 3x + 1 then

3x = y - 1

x = (y-1) / 3

x = f-1(x) = (x - 1)/3.

So:

Replacing the x  in y by (x - 1)/3 :-

x = f(-1)(y) = ( (3x + 1) - 1) / 3

= 3x / 3

= x.

So y = f(x).

Which type of parent function is graphed on the coordinate plane?
Sophie [7]

Answer : option A

In logarithmic Parent  function, there will be a vertical asymptote.

In the given graph , there is a horizontal asymptote. The graph goes close to y axis but does not cross y axis.

The graph goes close to y axis so there is a horizontal asymptote. Its not a parent logarithmic function.

The graph of exponential function with base 0 to 1 , the y value decreases when x increases. In the given graph the y values increases when x value increases. so the base of the exponential function will be greater than 1

Option A is correct
