Answer: p-0.6p
Step-by-step explanation:
60% = 0.6
Discount is 60% of price p = 0.6p
Original price less discount
p-0.6p
Sand to cement
7:3
210:x
ask yourself what number is needed to multiply by 7 to get 210 ( so you'd divide 210 by 7 which is 30). Multiply the other side by thirty as well to get the value of x
3*30 which is 90
41.1 is the answer to this question.
1. ab= 6 x 3 = 18 1) = 18
2. c + 4 = 2 + 4 = 6 2) = 6
3. a/b = 6/3 = 2 3) = 2
4. a - b - 6 - 3 = 3 4) = 3
5. 2c = 2(2) = 4 5) = 4
6. b/3 = 3/3 = 1 6) = 1
7. a - 1 = 6 - 1 = 5 7) = 5
8. 6 + c= 6 + 2 = 8 8) = 8
First step is to order the data from least to greatest.
10.5 11 11.5. 14.5 14.5 17 17 18 19
The median (Q2) is the middle number 14.5, this separates the lower half from the upper half. Q1 is the middle of the lower half, since there are an even amount of data, you have to take the average of the two middle numbers, 11 & 11.5, that would be 11.25; now we have to do the same with the upper half to find Q3, the average between 17 & 18 is 17.5
Now to find the IQR, subtract Q3 - Q1,
17.5 - 11.25 = 6.25
IQR = 6.25
