How many times will the digit "3" appear if we write all whole numbers from 1-9999?
Marysya12 [62]

Answer:

4000

Step-by-step explanation:

from 1 - 1000 = 300

1's    = 100

10's  = 100

100's = 100

1000's = 0

300 * 10 = 3000

then add in all the 3000's (ie 3001,3002, etc ) that adds one more thousand

3000 + 1000 = 4000

In the first semester, Jonas took seven tests in his math class. His scores were: 88 81 94 84 100 94 96.
maksim [4K]
The median is the middle-most number. First we need to put the numbers in order from lowest to highest:

81 84 88 94 94 96

The easiest way to find the median is to cross out the first and last number and then continue until you reach the middle.

So cross out 81 and 96:
84 88 94 94 are left.

Cross out 84 and 94:
88 and 94 are left.

Since we are left with 2 different numbers, we need to find the average of them and that’s our median. (88 + 94)/2 = 91

91 is the median.

givi [52]
Pounds: 10  20  30
Kilos:      4.5   9  13.5

half of 20 is 10, and half of 9 is 4.5.  So every 10 pounds is 4.5 kilos.  Add 10 to 20 to get 30, and add 4.5 to 9 to get 13.5.  Both parts of the ratio table are increasing at the same rate (either 10 eachtime or 4.5 each time).
