Probability of rolling a 1 = 1/6
Probability of rolling a 1 = 1/6

Multiply these together (1/6)x(1/6) to get your probability that this will occur twice in a row.

(1/6)X(1/6)=0.02777777778 (the 7 is repeating)

This rounds up to 2.8% chance, or 2.78% (depends on what decimal place you have to round it to)

A basketball team played 15 games and won 80% of them. If the team expects to play 30 games in all, how many more games must it
emmainna [20.7K]
So 80% of 15 games won equal 12 games won and 3 lost. This is because 15/10 = 1.5 and 1.5 x 8 =12.
For 30, you do the exact same thing but with 90% instead. 30/10 = 3. 3 x 9 = 27.
So they need to have won 27 games to get a 90% winning percentage out of 30 games.
But since the question asks how many MORE games they need to play, it'll be 27-12 = 15.
So they need to win 15 more games to get a 90% winning percentage

What is the average rate of change for this exponential function for the
zhannawk [14.2K]

Answer:

1.5

Step-by-step explanation:

The average rate of change is 1.5

when x=0 , the value of y =1

when x=2 the value of y = 4

<em>average rate of change formula = </em>\frac{f(b)-f(a)}{b-a}

a= 0 , f(a)=1

b=2, f(b)= 4

4 - 1 / 2 - 0 = 3/2 = 1.5

A kite was broken into two triangles.
Mekhanik [1.2K]
<h2>Answer:</h2><h2>Area of the kite = 80 cm^{2} , Area of traingle = 40 cm^{2} and height of the triangle, h = 5 cm</h2>

Step-by-step explanation:

A kite is broken into two triangles

Given the base of the traingle, b = 16 cm

Height of the triangle, h = 5 cm

Area of traingle = \frac{1}{2} (b.h)

= \frac{1}{2} (16) (5)

= 40 cm^{2}

Area of the kite = area of triangle 1 + area of triangle 2

  = 40 + 40

 = 80 cm^{2}
