Answer: Three standard deviation

Step-by-step explanation:

In a normal distribution, 99.7% of the values falls within three standard deviation from the mean.

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:

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°

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.

Answer:

D

Step-by-step explanation:

You can't be certain unless this figure is a square or a rectangle. The question should state what it is.

You are asked for HF in the question. I think you are given JG. Diagonals of a square or rectangle are equal and bisect each other.

HJ = GJ                 From the above statement.

2HJ = HF              HF is bisected.

2*15 = 30

HF = 30

The radius of a circle with the given equation is 5 units.

Given the following data:

Mathematically, the standard form of the equation of a circle is given by;

[tex](x-h)^2+(y-k)^2=r^2[/tex]

Where;

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.
