identify the type of sample used.
a computer generates a random list of telephone numbers to call to survey people about telephone fees.
a) convenience
b) simple random
c) stratified random
d) systematic

C.) Stratified random

Step-by-step explanation:

Definitions:

C.)Stratified random sample: The population is first split into groups. The overall sample consists of some members from every group. The members from each group are chosen randomly.

A.) Convenience sample: The researcher chooses a sample that is readily available in some non-random way.

B.) Simple random sample: Every member and set of members has an equal chance of being included in the sample. Technology, random number generators, or some other sort of chance process is needed to get a simple random sample.

D.) Systematic random sample: Members of the population are put in some order. A starting point is selected at random, and every ninth member is selected to be in the sample.

Hope this helps : )

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
