Using the probability concept, we have that:
- The probability that the student only plays football is: (c) 13 /33.
- The probability that the student plays baseball, but not football is: (d) 8/33.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
The total number of students is given by:
26 + 3 + 9 + 10 + 6 + 5 + 7 = 66
Of those, 26 play only football, hence the probability is:
p = 26/66 = 13/33
Which means that option c is correct for question 19.
Of those same 66 students, 9 + 7 = 16 play baseball but not football, hence the probability is:
p = 16/66 = 8/33
Which means that option d is correct for question 20.

Answer:I am not sure.
Step-by-step explanation:
8 times 25 times three is 600
Step-by-step explanation:
the numbers of the yellow and white counters
= 288- 38 = 250.
the ratio of yellow to white = 1:4
so,
the numbers of the yellow counters =
1/(1+4) × 250 =1/5 ×250 = 50
the numbers of the white counters =
4/(1+4) ×250 = 4/5 ×250 = 200
and the numbers of the red counters = 38
Answer:
Scale factor = 4 and it represents an 'enlargement'.
Step-by-step explanation:
We are given a hexagon which is dilated to form the second hexagon.
Now, as the size of the original hexagon is 0.2 units and the size of the dilated hexagon is 0.8 units.
As we get that 0.2 × 4 = 0.8
Therefore. it can seen that the original hexagon is dilated by 4 units in order to obtain new hexagon.
Moreover, dilation refers to the transformation that changes the size of the image.
Now, as we are changing the size by a scale factor of 4. So, this dilation is increasing the size of the original hexagon.
Hence, this dilation represents an enlargement.
