Answer:
x = 4
Step-by-step explanation:
We know that M is the mid-point of AB. So,
AM = BM ( A mid point divides a line segment into 2 equal parts. )
Also it's given that length of AM is 20 & length of BM is 3x + 8.
But as AM = BM ,
Answer:
Grace jumped for 9 minutes and Zoe jumped for 12 minutes
Step-by-step explanation:
Let Grace jumped for x minutes and Zoe jumped for y minutes
Grace jump no. of times in 1 minute = 66
Grace jump no. of times in x minutes = 66x
Zoe jump no. of times in 1 minute = 56
Zoe jump no. of times in x minutes = 56x
We are given that Their jumps today and together they jump 1266 times in the total of 21 minutes
So, x+y=21 ----1
66x+56y=1266 ---2
Substitute the value of x from 1 in 2
66(21-y)+56y=1266
y=12
x+y=21
x+12=21
x=21-12
x=9
Hence Grace jumped for 9 minutes and Zoe jumped for 12 minutes
The starting number is 245.So it’s already pretty deep in the water,then it goes down 83 feet MORE.so that’s 245+83=328 feet. Then the submarine goes UP 103 feet from that point,so 328-103=225 feet,so its closer to the surface than at the beginning(245ft)
Answer:
3/4(x^2)
Step-by-step explanation:
........................
Step-by-step explanation:
Probability is the ratio between number of successes to all events.
Probability = success / events
Odds are the ratio between number of successes to number of failures.
Odds = success / failure
If event A has a probability of 0.98, then there are 98 successes per 100 events, which means there are 98 successes per 2 failures. The odds of event A are 98/2 = 49/1.
If event B has a probability of 0.95, then there are 95 successes per 100 events, which means there are 95 successes per 5 failures. The odds of event B are 95/5 = 19/1.
The odds are relatively far apart compared to the probabilities. They make it seem that event A is much more likely than B, when in reality they have about the same probability.
