Since the central angle is a right angle, the labeled arc is 1/4 of the total circumference of the circle. The circumference of a circle with radius $r$ is $2\pi r$ , so we have

$\dfrac{2\pi r}4=18\pi\,\mathrm{in}\implies r=36\,\mathrm{in}$

Find the y-intercept of 2x - 3y = 6

Ksju [112]

Answer:

(0, - 2)

Step-by-step explanation:

The y-intercept is the value of y when x = 0. Substitute 0 for x in the equation and solve for y.

$2x - 3y = 6$

$2(0) - 3y = 6$

$- 3y = 6$

$\frac{ - 3y}{ - 3} = \frac{6}{ - 3}$

$y = - 2$

When x = 0, y = - 2.

For each of the situations described, state whether the sampling procedure is simple random sampling, stratified random sampling

aleksklad [387]

Answer:

The sampling method applied is Cluster sampling.

Step-by-step explanation:

A cluster sampling method is the type of sampling where first the entire population is divided into homogeneous groups. Then a random sample of these groups are selected.

After selecting a sample of groups, a random sample of fixed size is selected from each group.

In this case all freshmen are first divided into 30 sections, then 4 random sections are selected and the students in those 4 sections are sampled.

The sampling method applied is Cluster sampling.
