Consider all four-digit numbers that can be made from the digits 0-8 (assume that numbers cannot start with 0). What is the prob

vodomira [7]

Answer:

0.2498

Step-by-step explanation:

Number of 4 digit numbers that can be formed from the digit (0 - 8), assume number can't start from 0

Thus ;

First digit = (1, 2, 3, 4, 5, 6, 7, 8) = 8 ways

Next three digits = (0, 1, 2, 3, 4, 5, 6, 7, 8) = 9 ways

Hence,

Total possible outcomes = sample space = (8 * 9 * 9 * 9) = (8 * 9^3 ) = 8 * 729 = 5832

Required = number greater Than 7000

For number to be greater Than 7000, starting digit should be either 7 or 8

Hence,

First digit = 2 ways

Next three digits = 9 ways

Also excluding 7000

Hence, Number of digits above 7000;

2 * 9^3 = 2 * 729 = 1458 - 1 = 1457

Hence,

Probability = 1457 / 5832

= 0.2498285

= 0.2498

Answer, will mark brainliest ^^ (worth 61 points)

Sergio [31]

Answer:

1) ven diagram #1

2)160

3) 420

4)16

Step-by-step explanation:

1) lets make a ratio table:

(look at image below, sorry for the horrible writing)

the original ratios are 18 and 17, and 18+17=35 35 is the number of students who play either or both sports. 30 is the number who play either sport:

so 35-30=5

5 students play both sports:

18-5=13(baseball)

17-5=12(basketball)

2) add up all the students who do band or sports and subtract from the total number of students

89/464+215/464= 304/464 students play in band or orchestra or both, to find the number of students who dont:

464-304=160

3) 630/1000+420/1000=1050/1000

1050/1000-210/1000=840/1000

840/1000-420/100=420/1000

420 ppl use brand p

4) 15+9=24

40-24=16

16 ppl

hope this helps!

K(k + 1)(k + 2) – 3k(k + 1)<br><br> Need a step-by-step guide on how to factor this completely

Dimas [21]

Answer:

Step-by-step explanation:

k(k+1)(k+2) - 3k(k+1)

k and (k+1) are common to both terms.

k(k+1)(k+2) - 3k(k+1) = k(k+1)[(k+2) - 3] = k(k+1)(k-1)

Write an expression to describe the situation. "Your cell phone costs $50 a month plus $0.25 for each text message (t). Do not i

sveticcg [70]

The expression is 50 + 0.25t.

<h3>How to compute the value?</h3>

It should be noted that from the information, the cell phone costs $50 a month plus $0.25 for each text message (t).

The expression will be:

= 50 + 0.25(t)

= 50 + 0.25t

Therefore, the expression is 50 + 0.25t.
