For #2, the proportion would be .40/.25 and x/15, then you would cross multiply to find x. and for #3 the proportion would be 15/6 and 75/x and again you would cross multiply to find x. (:
To subtract 7/10 by 1/2, you need to find the common denominator. In this case, the common denominator would be 10. Multiply 1/2 by 5/5, which gives you 5/10. Now you can subtract 7/10 and 5/10.
Once you finish subtracting, you should get 2/10. This answer can be simplified to 1/5.
Answer: 16
Step-by-step explanation:
From the question, we are informed that there are 25 markers in a bag: 5 red, 5 yellow, 5 blue, 5 green, 5 purple and that one marker is drawn out of the bag, then put back in.
The probability of picking a blue marker will be: = 5/25 = 1/5
Therefore, the number of times that a blue marker will be expected to be picked in 80 draws would be:
= 1/5 × 80
= 16 times
