Answer:
The Richter scale and how it measures earthquake magnitude. The Richter scale calculates an earthquake's magnitude (size) from the amplitude of the earthquake's largest seismic wave recorded by a seismograph. ... (That is, an earthquake measuring 5.0 releases 31 times more energy than an earthquake measuring 4.0.)
Answer:
56 gray chairs
24 blue chairs
Step-by-step explanation:
ratio of gray to blue chairs in each row
Gray : blue = 7 : 3
Gray chairs = 7
Blue chairs = 3
Total ratio = 7 + 3
= 10
how many gray chairs and blue chairs will julio use if he sets up a total of 80 chairs
Number of gray chairs = 7/10 × 80
= 0.07 × 80
= 56 gray chairs
Number of blue chairs = 3/10 × 80
= 0.03 × 80
= 24 blue chairs
56 gray chairs
24 blue chairs
Answer:
2
Step-by-step explanation:
perpendicular means the opposite inverse of a slope. So -1/2 will become 2/1 or simply 2.
opposite means the sign will change, negative becomes positive and positive becomes negative.
inverse flip numerator and denominator.
Answer: The required probability of selecting 1 red apple and 2 yellow apples is 36.36%.
Step-by-step explanation: We are given that a bag contains 6 red apples and 5 yellow apples out of which 3 apples are selected at random.
We are to find the probability of selecting 1 red apple and 2 yellow apples.
Let S denote the sample space for selecting 3 apples from the bag and let A denote the event of selecting 1 red apple and 2 yellow apples.
Then, we have

Therefore, the probability of event A is given by

Thus, the required probability of selecting 1 red apple and 2 yellow apples is 36.36%.
