Answer:
<u>A simple random sample is a subset of a statistical population in which each member of the subset has an equal probability of being chosen. ... An example of a simple random sample would be the names of 25 employees being chosen out of a hat from a company of 250 employees</u>
<u>Step-by-step explanation:</u>
<u>i searched it up</u>
Solve each equation with (0, 3)
y = -x + 3
3 = -0 + 3
y = 3 (correct since y = 3 in (0, 3))
y = 2x - 3
3 = 2(0) - 3
3 = 0 - 3
3 = -3 (incorrect since it isn't equal)
So... No, because it does not check in the second equation.
Best of Luck!
Answer:
Solution given:
A(x,y))----reflection about x axis--->A'(x,-y)
P(2,1)---reflection about x axis----->Q(2,-1)
R(-6,-5)----reflection about x axis-->S(-6,5)
Answer:
another number =27
Step-by-step explanation:
Let X stand for the larger number. The smaller number is therefore X - 13. We can now write the sum of the two numbers as:
X + (X - 13) = 4
X + X - 13 = 41
Gather the X’s and rewrite as,
2X - 13 = 41
Add 13 to both sides to get
2X = 54
Divide both sides by 2 to solve for X,
X = 27

Find Y
To do this, we make use of the mid-point formula
i.e.
WX and ZY are the diagonals of the parallelogram.
The mid-point of WX is:
The mid-point of ZY is:
Equate both values of M
Multiply both sides by 2
By comparison:
Hence:
