Answer:
2/27
Step-by-step explanation:
This is a probability question and we are asked to estimate a particular probability. We proceed as follows:
The total number of sweets is given as 8 + 9+ 11= 28 sweets
He takes out a sweet to eat, the probability of this being a red sweet would be P(r1) = 8/28 = 2/7
Now he takes another sweet, we are asked to calculate the probability that this sweet is also red. Now after taking the first sweet, the number of sweets is now 27, while the number of red sweets is now 7. Hence the probability of having a red sweet taken in the second case would be p(r2) = 7/27
Now, the probability of both being red sweets can be calculated by multiplying both = 7/27 * 2/7 = 2/27
Let the width = X, then the length would be 5x ( 5 times as long as the width).
The perimeter is adding the 4 sides.
x + x + 5x + 5x = 70
Combine the like terms:
12x = 70
Divide both sides by 12:
x = 70/12
x = 5.83
The width = 5.83 cm.
The length = 5 x 5.83 = 29.15
Now round each length to the nearest tenth:
5.8 and 29.2 cm.
The answer is d.
A (−3, 1) and B (3, 4)
2 Let A have coordinates (x1, y1). Let (x1, y1) = (−3, 1).
3 Let B have coordinates (x2, y2). Let (x2, y2) = (3, 4).
4 Find the length AB by applying the
formula for the distance between
two points.
AB = "(x2 − x1)2 + (y2 − y1)2
= "[3 − (−3)]2 + (4 − 1)2
= "(6)2 + (3)2
= !36 + 9
= !45
= 3!5
= 6.71 1
