Answer:
8 were absent
Step-by-step explanation:
20% of 40 is 8
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
I don’t know for sure if this is right but I got f(-3)=1.
f(-3)= -x - 2
f(-3)= -(-3) - 2
The 2 negatives cancel each other out and make a positive.
f(-3)= 3-2
f(-3)=1
