if population function x has mean M(x)=2 and M(x²)=8, find its standard deviation
Answers
The standard deviation of the population function is 2
How to determine the standard deviation?The given parameters are:
M(x) = 2
M(x²)=8
The standard deviation is calculated using:
[tex]\sigma = \sqrt{M(x^2) - (M(x))^2[/tex]
Substitute known values
[tex]\sigma = \sqrt{8 - 2^2[/tex]
Evaluate the expression
[tex]\sigma = 2[/tex]

A six-sided die is rolled seven times. What is the probability that the die will show an even number at least six times?
Answers
Answer:
Step-by-step explanation:
Explanation
On a 6 sided die, there are three even numbers (2,4,6)
That's 1/2 the number on the die.
So getting 6 even numbers is
P(6) = 1/2 * 1/2 * 1/2 * 1/2 * 1/2 * 1/2 * 1/2 = 0.00781
Where did that extra 1/2 come from? Well one of the numbers thrown was an odd number, and it has to be counted.
P(7) = the same answer. 0.00781
Total 0.0156

Question in the Picture
Answers
Step-by-step explanation:
the picture is not representing the real angle sizes. so, don't let yourself get confused by that.
the right neighbor angle of 90° at E is also 90°.
it has to be, because it is the supplementary angle to the left 90° (that means together they are 180°).
remember, all angles around a single point on one side of a line have to sum up to 180° (because the line can be seen as the diameter of a circle, with the point being the center of the circle, and so one side of the line is representing a half-circle and therefore 180°).
for the same reason angle 1 (the lower neighbor of the 90° angle at A) is also 90°.
for the same reason the lower neighbor angle of the 60° angle at E is 180 - 60 = 120°.
for the same reason the angle ABC is 180 - 40 = 140°.
for the angle BCD we need to remember :
the sum of interior angles of a polygon with n sides is
(n − 2) × 180°.
in our case ABCDE has 5 sides, so the sum of all interior angles is
(5 - 2) × 180 = 3×180 = 540°
we know 4 of the interior angles already, so
angle BCD = 540 - 90 - 90 - 120 - 140 = 100°
x is now the supplementary angle to the angle BCD.
so,
x = 180 - 100 = 80°

Point Q is on line segment PR . Given PQ=16 and PR=19, determine the length of QR
Answers
Answer:
QR = 3
Step-by-step explanation:
given that Q is on the segment PR , then
PQ + QR = PR ( substitute values )
16 + QR = 19 ( subtract 16 from both sides )
QR = 3
The calculated length of the segment QR is 3 units
How to determine the length of the segment QRFrom the question, we have the following parameters that can be used in our computation:
Point Q is on line segment PR
PQ = 16 and PR = 19
using the above as a guide, we have the following:
PQ + QR = PR
substitute the known values in the above equation, so, we have the following representation
16 + QR = 19
So, we have
QR = 19 - 16

The table below shows the linear relationship between the number of weeks since birth and the weight of Samuel’s pet rabbit. Based on the table, what is the rate of change of the weight of the rabbit in pounds per week? Write your answer as a whole number or a decimal.
Answers
Based on the table, the rate of change of the weight of the rabbit in pounds per week will be 1.75 pounds.
How do explain the linear relationship?In the first week, there's 9.5 pounds. This can be illustrated using the arithmetic progression. The formula will be:
= a + (n - 1)d
where,
a = first term
d = common difference
3rd term = a + 2d
13 = 9.5 + 2d
2d = 13 - 9.5
2d = 3.5
d = 3.5/2
d = 1.75
Therefore, the rate of change of the weight of the rabbit in pounds per week will be 1.75 pounds.
