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
1.) set up the problem as if there were no decimals
4.) Multiply
2.) count the numbers behind the decimals in the problem
3.) count over that number of spaces from the right in your to place the decimal
When lines are parallel, they have the same slope, so the statement "line a and line b have the same slope" is TRUE
When lines are perpendicular, the slopes are opposites (the sign and number is flipped)
For example:
slope is 2
perpendicular line's slope is -1/2
slope is -1
perpendicular line's slope is 1/1 or 1
slope is 4/5
perpendicular line's slope is -5/4
When you multiply(the product) perpendicular slopes together, they equal -1. Since line c is perpendicular to line a and line b, the product of their slopes is -1.(so this is true)
The statement "the sum of the slopes of line a and b is 0" is false because if they have the same slope, when added together the result would not be 0. The slopes of line a and line b is -2/3, so the sum would be -4/3.
Answer:
$1,500
Step-by-step explanation:
To find how much money she made before paying taxes, divide 150 by 0.1:
150/0.1
= 1500
So, Kelly made $1,500 before taxes
Let's check the dot product .
v.w = 5(4)-2(10) = 20 -20 =0
So the dot product is not 20 . And since the dot product is zero, so they are perpendicular.
And the y component of w is 10.
So correct options are first and third .
