hi
Of the 72 students who have Ms. Darnell for Health/PE, 9 have an A. At this rate, how many of the 16 students in Ms. Jay’s homeroom would you expect to have an A? (1 point)

To find out how many students in Ms. Jay's homeroom would be expected to have an A, we can use proportions.
First, we can set up a proportion using the given information:
A/Total students = A/Total students in Ms. Darnell's homeroom
We know that in Ms. Darnell's homeroom, there are 72 students and 9 of them have an A. So we have:
9/72 = A/16
Now we can solve for A by cross multiplying:
9 * 16 = 72 * A
144 = 72A
Finally, we can solve for A by dividing both sides of the equation by 72:
A = 144/72
A = 2
Therefore, we would expect 2 students in Ms. Jay's homeroom to have an A.

To convert meters to feet, we can use the conversion factor of 3.28 feet per 1 meter.
So, to find out how many feet are in 15 meters, we can multiply 15 by 3.28:
15 meters * 3.28 feet/meter = 49.2 feet
Therefore, there are approximately 49.2 feet in 15 meters.
To determine how many students in Ms. Jay's homeroom would be expected to have an A, we can use the concept of proportions.
Step 1: Calculate the proportion of students with an A in Ms. Darnell's class.
We know that out of 72 students, 9 have an A. To find the proportion of students with an A, we divide the number of students with an A by the total number of students:
Proportion = Number of students with an A / Total number of students
Proportion = 9 / 72 = 0.125
Step 2: Use the proportion to find the number of expected students with an A in Ms. Jay's homeroom.
Since we have the proportion, we can apply this proportion to the number of students in Ms. Jay's homeroom (16) to find the expected number of students with an A:
Expected number = Proportion * Number of students
Expected number = 0.125 * 16 = 2
Therefore, based on the rate in Ms. Darnell's class, we would expect approximately 2 students in Ms. Jay's homeroom to have an A.
