The perimeter is 46cm
you find the width by dividing the area by the length and then add the length and width times 2 to get the perimeter
The answer to your question is 600 and 60
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.
we are given two points as
(2,4) and (-2,-4)
Let's assume
first point as (x1,y1)=(2,4)
so, x1=2 and y1=4
Second point as (x2,y2)=(-2,-4)
so, x2=-2 and y2=-4
now, we can use slope formula

now, we can plug values

now, we can simplify it

so, slope is 2 ..................Answer
