antiseptic1488 [7]

Answer:

Option b, c and e are wonderful approaches to solve the problem.

Step-by-step explanation:

Option (b) is appropriate this is because the option is talking about Simple random sampling where random universities are chosen to remove bias.

Option (c) is correct because this is an example of Stratified sampling where two homogenous groups (private and public universities are considered) and samples are chosen at random to remove bias

Option (e) is correct because this again is an example of Simple random sampling where 60 random STEM majors are chosen at random.

A circle has a radius of 5 ft, and an arc of length 7 ft is made by the intersection of the circle with a central angle. Which e
kirill115 [55]

We can use the arc length formula to solve this.

Arc length = \frac{q}{360}*2\pi r

Given arc length is 7 and radius is 5, we can plug in the values and solve for q.

7=\frac{q}{360}*2\pi (5)\\7=\frac{q}{360}*10\pi \\7=\frac{10\pi q}{360}\\7=\frac{\pi q}{36}\\7*36=\pi q\\252=\pi q\\q=\frac{252}{\pi}\\q=80.21


ANSWER:

We can use the equation 7=\frac{q}{360}*2\pi (5) to find the value of q. And, the value of q is 80.21°.
