Answer:
2√5
Step-by-step explanation:
d = √(x2 - x1)² + (y2 - y1)²
= √[1 - (-1)]² + [3 - (-1)]
= √(2)² + (4)²
= √(4) + (16)
= √20
= 2√5
Is it supposed to be equal to something, maybe "0"? You wouldn't be able to solve this without that.
Answer:
16/33
Step-by-step explanation:
We have a bag of :
9 red marbles
6 blue marbles
7 green marbles
11 yellow marbles
Total number of marbles = 33 marbles.
The possibility that a red or green marble will be selected from a bag
P( Red or Green) = P(Red) + P(Green)
In the question we are not told if it is with replacement or without. We do both
With replacement
P( R or G) = P(Red) + P(Green)
P(Red)= 9/33
P(Green) = 7/33
= 9/33 + 7/33
= 16/33
Therefore, the possibility that a red or green marble will be selected from a bag is 16/33
<u>Answer:</u>
12 units
<u>Step-by-step explanation:</u>
We are given these two points, (-7,-6) and (5,-6), and we are to find the distance between them.
We know the formula for finding the distance between two points:
<em>Distance = 
</em>
So putting in the values of the given coordinates in the above formula to get:
Distance = 
= 
Therefore, the distance between the two given points is 12 units.
