Kobotan [32]

Let x = amount of time the Arlen family must catch up to overtake the Harris family

In principle, the Harris and the Arlen family should cover the same distance. Since distance is speed x time,

45 (6+y) = 58y

270 + 45y = 58y

58y - 45y = 270

y = 270 ÷ 13

y= 20.77min

40. In a statistics class of 30 students, there were 13 men and 17 women. Two of the men and three of the women received an A in

Harrizon [31]

Answer:

a) 56.67% probability that the student is a woman

b) 16.67% probability that the student received an A

c) 63.33% probability that the student is a woman or received an A.

d) 83.33% probability that the student did not receive an A.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

We have that:

30 students

13 men

17 women

2 men that got an A and 11 men that did not get an A.

3 women that got an A and 14 women that did not get an A.

a. Find the probability that the student is a woman.

30 students, of which 17 are women.

$P = \frac{17}{30} = 0.5667$

56.67% probability that the student is a woman

b. Find the probability that the student received an A.

30 students, of which 5 received an A

$P = \frac{5}{30} = 0.1667$

16.67% probability that the student received an A

c. Find the probability that the student is a woman or received an A.

30 students, of which 17 are women and 2 are men who received an A. So

$P = \frac{19}{30} = 0.6333$

63.33% probability that the student is a woman or received an A.

d. Find the probability that the student did not receive an A.

30 students, of which 25 did not receive an A.

$P = \frac{25}{30} = 0.8333$

83.33% probability that the student did not receive an A.

Using the numbers 2,0,1,9 in order what exoression do you make to equal 6

alexgriva [62]

Answer: $9-(0+1+2)$

Step-by-step explanation:

We have given the numbers = 2,0,1,9

We can use addition and subtraction operation to the given numbers such that the answer will be equals to 6.

We can add 2 ,0 and 1 and then subtract from 9 , we will get 6.

So the required expression can be

$9-(0+1+2)\\=9-(3)\\=9-3\\=6$

hence, the required expression can be $9-(0+1+2)$
