Answer:

42%

Step-by-step explanation:

1) so out of the 50 girls surveyed, only 21 students played in the league. We can write this as 21/50

to convert this into percentage multiply by 2 on both sides:

21*2=42

50*2=100

42/100=42%

42% of girls played in the league

hope this helps!

Given the parent function f(x) = x², define the function g(x) that

Bas_tet [7]

Answer:

Part 1) $g(x)=-x^{2}$

Part 2) $g(x)=(x+3)^{2}$

Part 3) $g(x)=x^{2}+7$

Step-by-step explanation:

we have

The parent function is $f(x)=x^{2}$

This is a vertical parabola open upward with vertex at origin (0,0)

Part 1) Reflection over the x-axis

The rule of the reflection across the x=axis is equal to

(x,y) ------> (x,-y)

f(x) -----> g(x)

The function g(x) will be

$g(x)=-x^{2}$

Part 2) Horizontal shift left 3 units

The rule of the translation is

(x,y) ------> (x-3,-y)

f(x) -----> g(x)

The function g(x) will be

$g(x)=(x+3)^{2}$

Part 3) Vertical shift up 7 units

The rule of the translation is

(x,y) ------> (x,y+7)

f(x) -----> g(x)

The function g(x) will be

$g(x)=x^{2}+7$

10*12= 120 the bottom of the box
10*7.5= 75 one side

12*7.5= 90 another side
90*2= 180 two other sides
120+150+180 = 450

If you flipped the coin 100 times, how many heads would you expect to get? Explain your answer.

Irina18 [472]

Answer:

You would expect to get 50 heads

Step-by-step explanation:

Each time you flip a coin you will either get heads or tails. This means that you have a 1/2 probability of getting heads. If you use this then you need to multiply 1/2 and 100 to get the expected amount of heads. Multiplying by a half is just dividing by 2. Therefore, the answer is 100/2 = 50. The answer is 50 heads
