Nady [450]

The odds that local amateur ice skater will win in next regional competition when probability is given will be 43 to 57.

We have,

Probability that ice skater will place first in the next regional competition i.e. P = 0.43,

And,

Now,

According to the question,

The odd when probability is given is find out by using the below mentioned formula,

i.e.

Odds = \frac{P}{1-P}

Now,

Substituting the value of probability,

i.e.

Odds of winning this competition = \frac{0.43}{1-0.43}

On solving we get,

Odds of winning this competition = \frac{43}{57}

i.e.

The Odds of winning this competition are 43 to 57.

Hence we can say that the odds that local amateur ice skater will win in next regional competition when probability is given will be 43 to 57.

I need help with these three equations <br> 3x - 2 = x + 10<br> X+4=19-2x<br> 8z - 20 =z +15
lapo4ka [179]

Answer:

1st answer is 6, 2nd is 5, 3rd is 5

Step-by-step explanation:

3x-2=x+10

3x-x=10+2

2x=12

x=12÷2

x=6

x+4=19-2x

x+2x=19-4

3x=15

x=15÷3

x=5

8z-20=z+15

8z-z=15+20

7z=35

z=35÷7

z=5
