What is empirical rule?
Empirical rule states that for a normal distribution, 68% of the values falls within one standard deviation from the mean, 95% of the values falls within two standard deviation from the mean and 99.7% of the values falls within three standard deviation from the mean.
Hence:
In a normal distribution, 99.7% of the values falls within three standard deviation from the mean.

Answer:
=2xy²+2x²y
Step-by-step explanation:
Delete the parenthesis of both operations.
= x²y - 3y² + 5xy² + x²y - 3xy² - 3y²
Then you have to make the simplification
= 2xy²+2x²y

Miss Solan is buying doughnuts and coffee for her classes. The total came out to $32.12. If the coffee costs $5.96 and each doughnut is $1.09 ,how many doughnuts did she buy?
Answer:
24
Step-by-step explanation:
First, start off by subtracting the cost of the coffee ($5.96) from the total cost of $32.12. This would give you $26.16. From here, if you multiply 24 by the cost of each doughnut ($1.09) you would get $26.16 which is the total amount of money that was spent on doughnuts. Miss Solan bought 24 doughnuts.

Answer:
33°
Step-by-step explanation:
<ACD =90-33 =57°
<DCB=<ACB - <ACD
=90° -57 =33°
In triangle ACD the only angle that has not been found is <ACD so you find it by adding 90+33 and subtracting from 180° to get 57°. <ACB =90° and <ACD = 57° ,the angle in question is<DCB which is part of< ACB. So to get <DCB you do 90°-57°=33°.
B = 180 - 90 - 33 = 57°
C in DCB tringle = 180 - 90 - 57 = 33°
So C in DCB triangle = 33°
Find the area of the rhombus . Each indicated distance is half the length of its respective diagonal.
12ft
5ft
Given:
The length of diagonals of a rhombus are 12 ft and 5 ft.
To find:
The area of the rhombus
Solution:
Area of a rhombus is:
[tex]Area=\dfrac{d_1d_2}{2}[/tex]
Where, [tex]d_1,d_2[/tex] are two diagonals of the rhombus.
It is given that the length of diagonals of the rhombus are 12 ft and 5 ft.
Putting [tex]d_1=12,d_2=5[/tex], we get
[tex]Area=\dfrac{12\times 5}{2}[/tex]
[tex]Area=\dfrac{60}{2}[/tex]
[tex]Area=30[/tex]
Therefore, the area of the rhombus is 30 square ft.

What is the radius of a circle whose equation is x2+y2+8x−6y+21=0?
2 units
3 units
4 units
5 units
Answer:
2 units
Step-by-step explanation:
none
The radius of a circle with the given equation is 5 units.
Given the following data:
[tex]x^2+y^2+8x-6y+21=0[/tex]The equation of a circle.Mathematically, the standard form of the equation of a circle is given by;
[tex](x-h)^2+(y-k)^2=r^2[/tex]
Where;
h and k represents the coordinates at the center.r represents the radius of the circle.Expanding the equation, we have:
[tex]x^2+y^2-2hx-2ky+(h^2+k^2-r^2)=0\\\\r=\sqrt{h^2+k^2}[/tex]
Comparing the terms, we have:
-2hx = 8x
h = -4
-2ky = -6y
k = 3.
For the radius:
[tex]r=\sqrt{-4^2+3^2}\\\\r=\sqrt{16+9} \\\\r=\sqrt{25}[/tex]
r = 5 units.
