Answer: statistic.
Step-by-step explanation:
A parameter is a measure of characteristic in a population.
A statistic is a measure of characteristic in a sample.
Given: A survey of 32 out of 50 in a basketball game showed 20.5% enjoyed the game.
Since group of 32 games out of 50 is representing a sample here.
So, 20.5% is the measure of sample, i.e. it is a statistic.
Answer:
-8,-29
Step-by-step explanation:
a - b = 21 --------------------------Equation 1
5a - 2b = 18 ----------------------Equation 2
From Equation 1, a = 21 + b
Putting the values of a in Equation 2 we get;
5(21 + b) - 2b = 18
105 + 5b - 2b = 18
3b = 18 - 105
b = -87 / 3
b = -29
Putting the values of b in Equation 1 we get;
a = 21 + (-29)
a = 21 - 29
a = -8
