Answer:
3 and 4
Step-by-step explanation:
We apply 2 transformations here.
f(x) ----> f(x + a) - this is a shift of a units to the left.
f(x) ---- > f(x) + a - this is a shift of a units vertically up.
x - 1 ----> x + 2 shifts it 3 units to the left.
3 ---->5 shifts it 2 units up.
Answer:
CD = 2 units
Step-by-step explanation:
in the given right triangle ΔCDE,
By applying tangent rule,
tan(∠E) =
=
tan(30)° =
CD =
CD = 2 units
Therefore, CD = 2 unit will be the answer.
Answer: (B) Systematic
Step-by-step explanation:
(A) Random : In this researcher randomly selects individual from population to make sample.
(B) Systematic : It is a kind of random sampling method where researcher decide the starting point to select individual , then follow a systematic pattern to select them.
(C) Stratified : It is a kind of random sampling method where researcher divides the population into groups ( on the basis of characteristics) called as strata , then selects individuals from each strata.
(D) Cluster : It is a kind of random sampling method where researcher divides the population into groups known as clusters , then randomly selects clusters to include in sample.
(E) Simple random : It is a kind of random sampling method where researcher randomly selects individual from population to make sample.
Since , a random number is generated to determine a starting position in the list and then every tenth attendee is placed in the sample.
That means sponsors follow as systematic pattern.
Therefore , the methods was used to select the probability sample : (B) Systematic
