The values that exist two standard deviations above and below the mean are 681 and 265.
<h3>How to determine the values?</h3>The given parameters exist:
Mean = 473
Standard deviation =104
The values above and below the mean exist calculated utilizing:
In this case n = 2.
So, we have,
The value above is:
x = 473 + 2 104 = 681
The value below is:
x = 473 - 2 104 = 265
Therefore, the values that exist two standard deviations above and below the mean are 681 and 265.

Answer:
see explanation
Step-by-step explanation:
the sum to n terms of an arithmetic sequence is
=
[2a + (n - 1)d ]
where d is the common difference and a is the first term
here d = 9 - 7 = 7 - 5 = 2 and a = 5, hence
=
[(2 × 5) + 2(n - 1) ]
= (10 + 2n - 2)
= (2n + 8)
= n² + 4n
When sum = 165, then
n² + 4n = 165 ← rearrange into standard form
n² + 4n - 165 = 0 ← in standard form
(n + 15)(n - 11) = 0 ← in factored form
equate each factor to zero and solve for n
n + 15 = 0 ⇒ n = - 15
n - 11 = 0 ⇒ n = 11
but n > 0 ⇒ n = 11
Answer:
Length of rectangular cake = 5 cm
Breadth of rectangular cake = 6 cm
Area of rectangle = 5 cm × 6 cm =30 cm²
If cake is equally distributed between Honey and Money, then areas of two parts should be equal.
So, Amount of cake that Honey and money got
Share of each (Honey and Money)=15 cm²
So, if the third cake if it was cut diagonally ,the cake must have some height.
Let the height of cake be H.
So, Height of third cake
If , H=0 that is height is negligible having 0 thickness,
Then the Length of third cake, which is divided into two parts=√61=7.81 cm
