What percent of students prefer burgers?

1 answer:

AleksandrR [38]3 years ago

4 0

Answer:

40 (without the percent sign because the question doesn’t want you to put it)

Step-by-step explanation:

This is a very reasonable diagram because the 216˚ plus the 144˚ equal 360˚, which is sensible because a circle is 360˚ (degrees). So, you can just do 144 divided by 360 to find the percent of the circle, which equals 0.4, and 0.4 as a percent is 40%. But the question doen’t want to you to put the percent sign. So the answer is just 40.

He didn’t multiply the equation by 1/2 in the second part so it threw his whole answer off. Hope this helps

In a horse race with 5 horses, you make a bet by predicting the ranking of all 5 horses. Suppose you place your bet at random. W

lapo4ka [179]

Answer:

P( top two horses are predicted incorrectly in incorrect order)

= $\frac{1}{2}$

Step-by-step explanation:

In the horse race the outcome can be predicted in 5! = 120 ways.

Now suppose the top two horses were predicted incorrectly in incorrect order. Now, the top horse can be predicted incorrectly in 4 ways.

Suppose the top horse was predicted to be in k-th position where k = 2, 3 ,4,5

so the second horse can be predicted to be in place from 1 to (k - 1)

So, the top two horses can be predicted incorrectly in incorrect order

in $\sum_{k =2}^{5}(k - 1)$ = 10 ways

and for each prediction of the two the remaining horses may be predicted in 3! = 6 ways.

Hence ,

P( top two horses are predicted incorrectly in incorrect order)

= $\frac{6 \times 10}{120}$

= $\frac{1}{2}$
