Answer:
$103.14
Step-by-step explanation:
The calculation of slips are amounted to a total of $103.14
2x+x=36
Kim's Sister age
2x+x=36 Add "x and 2x"
3x=36 Divide both sides by 3
÷3 ÷3
x=12
Kim's sister is 12 years old
Soo....
Multiply that by two to get Kim's age
12•2=24 Kim is 24 years old.
Answer:
2/27
Step-by-step explanation:
This is a probability question and we are asked to estimate a particular probability. We proceed as follows:
The total number of sweets is given as 8 + 9+ 11= 28 sweets
He takes out a sweet to eat, the probability of this being a red sweet would be P(r1) = 8/28 = 2/7
Now he takes another sweet, we are asked to calculate the probability that this sweet is also red. Now after taking the first sweet, the number of sweets is now 27, while the number of red sweets is now 7. Hence the probability of having a red sweet taken in the second case would be p(r2) = 7/27
Now, the probability of both being red sweets can be calculated by multiplying both = 7/27 * 2/7 = 2/27
