Answer:

5 - number summary:

Minimum : 664

First quartile : 706

Median : 766

Upper quartile : 810

Maximum : 836

Step-by-step explanation:

Given the data:

664, 693, 698, 714, 751, 753, 779, 789, 802, 818, 834, 836

Sorted data :

664, 693, 698, 714, 751, 753, 779, 789, 802, 818, 834, 836

Minimum =664

Lower quartile (Q1) = 1/4(n+1)th term

Q1 = 1/4(13) = 3.25 = (3rd + 4th) = (698 + 714) / 2 = 706

Median (Q2) = 1/2(n+1)th term

Q2 = 1/2(13) = 6.5 = (6th + 7th) = (753 + 779) / 2 = 766

Upper quartile (Q3) = 3/4(n+1)th term

Q3 = 3/4(13) = 9.75 = (9th + 10th) = (802 + 818) / 2 = 810

Maximum = 836

Leni [432]
<h3>Answer:</h3>

99.90%

<h3>Step-by-step explanation:</h3>

STEPS:

  1. Find the total amount
  2. Find out what number of what we want to know the percentage of there are out of the whole amount there is. (Divide the percentage amount we want to find by the total amount)
  3. Turn into a percentage by multiplying by 100

Find the total sum

30.2 mil = 30,200,000 small businesses + 30,000 other = 30,230,000 total

Find the fraction that small businesses make up of the total

\frac{small~businesses}{total~businesses} = \frac{30,200,000}{30,230,000} = 0.9990

Convert to percentage

0.9990 → % = 0.9990 × 100 = 99.90%

Hope this helps,

Let X be a random day of the week, coded so that Monday is 1, Tuesday is 2, etc. (so X takes values 1, 2,..., 7, with equal prob
Akimi4 [234]

Answer:

Yes. Have the same distribution.

Step-by-step explanation:

Given that X is a random day of the week, coded so that Monday is 1, Tuesday is 2, etc. (so X takes values 1, 2,..., 7, with equal probabilities).

Y is the next day after X

So Y can be written as X+1

But since highest value is 7, we can write

Y = X+1 mod 7

i.e. whenever X=7, Y= 8= 1 again.

Thus Y can take values as

Y  1   2   3   4   5   6   7

P(Y) = P(X+1) = 1/7

i.e. Y also has the same distribution as X
