Answer:
Step-by-step explanation:
8y+14=3y+49
-3y . -3y
5y+14=49
-14 -14
5y=35 divide both sides by 5
y=7
Answer:
33
Step-by-step explanation:
2/5x40=16
40-16=24
24+9=33
Answer:
Option (3) will be the answer.
Step-by-step explanation:
Area of a triangle = 
= 
Since, m∠A + m∠B + m∠C = 180°
60° + 60° + m∠C = 180°
m∠C = 180° - 120°
m∠C = 60°
Therefore, ΔABC is an equilateral triangle.
AB ≅ BC ≅ AC ≅12
Sin 60° = 

CD = 6√3
Now area of ΔABC = 
=
= 62.35
≈ 62.4 square units
Therefore, Option (3) will be the answer.
Answer:
A correlation coefficient is a numerical measure of some type of correlation, meaning a statistical relationship between two variables. The variables may be two columns of a given data set of observations, often called a sample, or two components of a multivariate random variable with a known distribution.
