Answer:
The correct option is C) The results do not apply to any population because this was a voluntary response sample.
Step-by-step explanation:
Consider the provided information.
A statistics student used the information from the poll to calculate the 95% confidence interval.
A voluntary response sample is made up of volunteers. these types of samples are always biased.
Because the people who join the sample have strong opinions about a topic in either direction.
Therefore, the correct option is C) The results do not apply to any population because this was a voluntary response sample.
Answer:
x^9
Step-by-step explanation:
If we have x^2 * x^3 we have (x * x) * (x * x * x) = x * x * x * x * x = x^5 which demonstrates that x^a * x^b = x^(a+b), 4 + 5 = 9
Answer:
I tried looking it up, and i found 15 square units. sorry if its wrong :(
Step-by-step explanation:
Answer:
Height = 14.4
Step-by-step explanation:
The diagonals meet at right angles. Interesting property.
The hypotenuse is the side of the rhombus = 15 cm
One of the sides of the small triangles created by the intersection of the diagonals = 24/2 = 12
You can find the other side of the the triangle by using the Pythagorean Theorem
a^2 + b^2 = c^2
c = 15
a = 12
b = ?
12^2 + b^2 = 15^2
144 + b^2 = 225
b^2 = 225 - 144
b^2 = 81
b = 9
The area of this right angle = 9 * 12/2 = 54
There are 4 of them so 4 * 54 = 216
That's the area of the rhombus.
The h= Area / b
b = 15
h = 216/15
h = 14.4
