The next 3 numbers are 184, 375, and 758. Subtract the numbers (8-3, 19-8, 43-19 etc) you get a trend of 5, 11, 23, 47 and 95, if you subtract those (11-5, 23-11, 47-23) you get a trend of 6, 12, 24, which is just multiplied by 2 (6 x2 is 12, 12x 2 is 24). You can complete that by multiplying by two. You’ll notice that compared with that on both sides you’ve got 6, 12, 24, 48, and on another side you’ve got 5, 11, 23, 47 (one side is smaller by 1). You can add to get the next number in the sequence from 5, 11, 23, 47, etc. (3+5=8, 8+11=19........89+95=184, 184+191= 375, 375+ 383= 758. Hope that helped
Answer:
Less than 30: 26
Less than 40: 62
Less than 50: 75
Less than 60: 78
Less than 70: 85
Less than 80: 86
Less than 90: 88
Step-by-step explanation:
We have this frequency information:
20-29: 26
30-39: 36
40-49: 13
50-59: 3
60-69: 7
70-79: 1
80-89: 2
We can add each category and have a cumulative frequency table
<30: 26
<40: 26+36 = 62
<50: 62 +13 = 75
<60: 75 + 3 = 78
<70: 78 + 7 = 85
<80: 85 + 1 = 86
<90: 86 + 2 = 88
Answer:
<u>3/40</u>
Step-by-step explanation:
Probability (Quarter 1st) :
⇒ Number of quarters / Number of coins
⇒ 5 / 9 + 3 + 8 + 5
⇒ 5/25
⇒ 1/5
============================================================
The coin is not replaced.
Probability (Penny 2nd) :
⇒ No. of pennies / Total - 1
⇒ 9 / 25 - 1
⇒ 9/24
⇒ 3/8
==========================================================
Probability (both) :
⇒ 1/5 × 3/8
⇒ <u>3/40</u>
Average is the total of the numbers divided by the amount of numbers.
36 is the answer.
