Answer.
a. Population is the total number of voters in the constituency, that is 10000
b. the parameter is the unknown character of the population, that is 35% of 10000= 3,500
c. Statistics of interest is know character from the sample, that is 40% of 200= 80
d. The two answers are not surprisingly, because the sample is a portion of the population and we expect it to be smaller that the population. Thus, parameter must be bigger than statistics of interest.
d) ii. If another 200 sample was to be taken, we expect to see an increase in a statistics of interest.
Thus my answer, please help by your approval as fast as you can
Hi.
I believe the formula for R when you have the voltage and current is:
V/I = R
Plugging in the numbers:
220/4 = 55
The answer is the second option, 55.
Similar triangles have corresponding sides with proportional lengths.
AB/BC = DE/EF
5/9 = 7.5/EF
5(EF) = 9 * 7.5
5(EF) = 67.5
EF = 13.5
Answer:
x < 3
Step-by-step explanation:
−4x − 8 > −20
Add 8 to both sides.
-4x > -12
Divide both sides by -4. Remember that when you multiply or divide both sides of an inequality by a negative number, the direction of the inequality sign changes.
-4x/(-4) < -12/(-4)
x < 3
The parabola goes down(makes a sad face) because it is negative. The answer is 0,0
