Step-by-step explanation:
given,
measures of 3 angles of triangle,
angle 1 = 3x
angle 2 = 2x + 15°
angle 3 = 3x + 5 °
sum of the angles should be 180°
so,
angle 1 + 2 + 3 = 180°
after inserting the values we got,
3x + 2x + 15 + 3x + 5 = 180°
→ 8x + 20 = 180°
→ 8x = 180 - 20 = 160°
→ x = 160/8 = 2
→ x = 20
therefore,
angle
1 = 3x = 3 × 20 = 60
2 = 2x + 15 = 2(20) + 15 = 55°
3 = 3x + 5 = 3(20) + 5 = 65°
as given,
their sum should be 180° so,
60 + 55 + 65 = 180°

Answer: Option 'C' is correct.
Step-by-step explanation:
Since we have given that
A pollster uses a computer to generate 500 random numbers, then interviews the voters corresponding to those numbers.
Since Random sampling includes putting all names into a bowl and draw certain names. .In this type of sampling, each and every elements has equal chance of occuring.
Cluster sampling includes dividing the population into groups specially geographically and these groups are called clusters and in which each element of selected group are used.
Stratified sampling divides into group known as strata but not geographically.
This type of sampling that is used is Stratified sampling.
Hence, Option 'C' is correct.
Answer:
x=9
Step-by-step explanation:
3x-x = 22-4
2x = 18
x = 18/2
x=9

Answer:
40
Step-by-step explanation:
0.13 ⟌5.2 (We can move 0.13 over two spots)
13⟌520 (We move the decimal two spots because of previous)
We have
₄ ₀
13⟌520
- 52
______
0 0
- 0
______
0
So 40 is our final answer.
