Answer:
He should expect to select 75 yellow cards.
Step-by-step explanation:
Since there is replacement, for each trial, we have:
1 yellow card
1 red card
1 blue card
1 green card.
If Greg does this 300 times, how many yellow cards should he expect to select?
Each trial, there are 4 cards, one of which is yellow. So 1/4 = 0.25 probability of selecting a yellow card.
Over 300 trials
0.25*300 = 75
He should expect to select 75 yellow cards.
(predicted value - exact value)/exact value * 100
(31 - 34)/34 * 100 = 8.8%
Answer:
Yes.
Step-by-step explanation:
Let's write out each problem:
= 2.3
= 8
Now that we have both answers to each expression, we can tell that , in fact, is larger than the square root of 5.
So your answer is, "Yes, is bigger than the square root of 5.

Answer:
They both have area 4
Step-by-step explanation:
Area of the square:
Area of the triangle:
Using the left-side of the triangle as the base, and the height from the left-side to the bottom-right corner:
We know the length of the diagonal is 
as we are using a centimetre grid, so we can create an isosceles triangle with side lengths 1 and our unknown length, we can then use Pythagorean Theorem to work out our unknown side length.
