Answer:
available is 111.5cm tall and Olivia is 88.5cm
Step-by-step explanation:
ok so Olivia is half the height of Luca which means the height of Luca divided by 2
177÷2=88.5
so Olivia is 88.5cm tall
we know that Available is 23cm taller than Olivia which means
the height Available= the height of Olivia+ 23cm
=88.5+23
=111.5
so Available is 111.5cm tall
Answer:
A red 5 is chosen from the deck. The card is put back into the deck and the a red card is chosen.
Step-by-step explanation:
An independent event is one whose outcome is not dependent on any other event. There are two types of cards in the deck. If a red card is selected it will be from the series 1 - 20, if the card is put back into deck and then again a red card is selected it will be again from the series 1 - 20. This is an independent event since its outcome is same irrespective of the events.
Answer:
x = 2
Step-by-step explanation:
Both equations are equal to y, so they're also equal to each other. We then set them equal to each other:
x^2 - 2x + 1 = x^2 + 2x - 7
We now do algebra to isolate x. Subtract 1 from both sides.
x^2 - 2x = x^2 + 2x - 8
Subtract 2x from both sides.
x^2 - 4x = x^2 - 8
Subtract x^2 from both sides.
-4x = -8
Divide both sides by -4.
x = 2
