Answer: BOC is 80 COD is

60 (i think I’m not sure)

Step-by-step explanation:

DOF is 120 minus 40 (cuz it’s a vertical angle and is parallel from the other one) is 80 and I got 60 for COD because 80+80+40+40=240 a circle is 360 so 360-240=120 and since it’s two vertical angles you have to divide it by 2 to get 60. Again thts only what I think so Idk if it’s right or not this is what I think the answer is.

Use the relative frequency approach to estimate the probability of the event. In a certain class of students, there are 8 boys f
In-s [12.5K]

Answer:

P\text{Student will be from Kenilworth}\approx 0.256

Step-by-step explanation:

We have been given that that there are 8 boys from Wilmette, 5 girls from Kenilworth, 9 girls from Wilmette, 5 boys from Glencoe, 5 boys from Kenilworth and 7 girls from Glenoce.

The total number of students from Kenilworth is 5 boys plus 5 girls that is 10 students.

The total number of students in the class would be 8+5+9+5+5+7=39

\text{Probability}=\frac{\text{Number of favorable outcomes}}{\text{Total number of possible outcomes}}

P\text{Student will be from Kenilworth}=\frac{\text{Number of student from Kenilworth}}{\text{Total number of students}}

P\text{Student will be from Kenilworth}=\frac{10}{39}

P\text{Student will be from Kenilworth}=0.2564102564

P\text{Student will be from Kenilworth}\approx 0.256

Therefore, the probability, that the student will be from Kenilworth, is approximately 0.256.
