The standard deviation of the possible outcomes of the binomial trial, given the success rate and the number of trials is 10.
How to find the standard deviation ?The standard deviation measures the spread or dispersion of the possible outcomes around the mean and a higher standard deviation means that the possible outcomes are more spread out, while a lower standard deviation means that the possible outcomes are more closely clustered around the mean.
To find the standard deviation of this binomial distribution, first find the variance by the formula:
= Number of trials x probability of success x ( 1 - probability of success )
= ( 500 x 0. 2 x ( 1 - 0. 2))
= 100
Then, the standard deviation would be:
= √(Variance )
= √(100)
= 10

Answer:
0.2693
Step-by-step explanation:
Thus is a binomial probability problem :
p = 0.36
1 - p = 0.64
n = 9
x = 3
Using the binomial probability relation :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
P(x = 3) = 9C3 * 0.36^3 * 0.64^6
P(x = 3) = 84 * 0.36^3 * 0.64^6
P(x = 3) = 0.2693

For example:
Addition. In this equation, you can add all of the coefficients (2, 5, and 4) because the variables are the same (a).
2a + 5a + 4a = 11a
Subtraction. In this equation, you can subtract all of the coefficients (11, 5, and 4) because the variables are the same (a).
11a – 5a – 4a = 2a

Which is ordered in ascending order
To do this, it is best to convert the fractions to decimal and then make comparison.
From the options, only (b) is ordered in ascending order and the proof is as follows.
[tex]\{\frac{1}{8},\frac{1}{4},\frac{1}{2}\}[/tex]
Convert to decimals
[tex]\{0.125, 0.25, 0.5\}[/tex]
By comparison:
[tex]0.125< 0.25< 0.5[/tex]
Hence, (b) is ordered from least to greatest

exponential function models the annual rate of increase. Find the monthly and quarterly rates
9514 1404 393
Answer:
1. monthly: 0.25%; quarterly: 0.75%
2. monthly: ≈ 0.45833%; quarterly: 1.375%
Step-by-step explanation:
In each case, the base of the exponential term is the annual growth factor. The annual growth rate (interest rate) is ...
growth rate = growth factor - 1
Then the monthly rate is ...
monthly rate = growth rate/12
and the quarterly rate is ...
quarterly rate = growth rate/4
__
1. monthly rate = (1.03 -1)/12 = 0.03/12 = 0.0025 = 0.25%
quarterly rate = (1.03 -1)/4 = 0.03/4 = 0.0075 = 0.75%
__
2. monthly rate = (1.055 -1)/12 = 0.055/12 ≈ 0.0045833 = 0.45833%
quarterly rate = (1.055 -1)/4 = 0.055/4 = 0.01375 = 1.375%

An architect is designing square windows with an area of(x2 + 16x +64) ft?. The dimensions of the
windows are of the form ax +b, where a and b are whole numbers.
Part 1 out of 2
Find an expression for the perimeter of the windows.
The perimeter of the square is represented by
(x+
6 ft.
A) The dimensions are (x+10) by (x+10).
B) The perimeter is given by 4x+40.
C) The perimeter when x is 4 is 56.
The quadratic can be factored by finding factors of c, the constant, that sum to b, the coefficient of x. Our c is 100 and our b is 20; we want factors of 100 that sum to 20. 10*10=100 and 10+10=20, so those are what we need. This gives us (x+10)(x+10 for the factored form.
Since the dimensions are all (x+10), and there are 4 sides, the perimeter is given by 4(x+10). Using the distributive property we have 4*x+4*10=4x+40.
To find the perimeter when x=4, substitute 4 into our perimeter expression:
4*4+40=16+40=56.
Answer:
A) The dimensions are (x+10) by (x+10).
B) The perimeter is given by 4x+40.
C) The perimeter when x is 4 is 56.

Which of the following equations could be solved to determine the length of RS?
Answer:
[tex] \frac{Sin(80)}{RS} = \frac{Sin(52.5)}{7} [/tex]
Step-by-step explanation:
Given:
S = 52.5°
s = QR = 7
Q = 80°
q = RS = ?
Required:
Equation that could be used to find the length of RS
Solution:
We would need the law of Sines which is given as:
[tex] \frac{Sin(A)}{a} = \frac{Sin(B)}{b} = \frac{Sin(C)}{c} [/tex]
Applying the Law of Sines, we would have the following equation:
[tex] \frac{Sin(Q)}{q} = \frac{Sin(S)}{s} [/tex]
Plug in the values
[tex] \frac{Sin(80)}{RS} = \frac{Sin(52.5)}{7} [/tex]
Therefore, the equation that can be used to determine the length of RS is [tex] \frac{Sin(80)}{RS} = \frac{Sin(52.5)}{7} [/tex]

Kori has 12 strawberries, 3 pineapples, and 4 kiwis. What is the ratio of strawberries to total fruit?
HELP!
Answer:
12:19
Step-by-step explanation:
To create a ratio, we compare a portion to a whole. In this case our portion is 12 strawberries. Our whole is the total fruit, so let's add up each fruit to find the total.
12 + 3 + 4 = 19
Now we have our portion (12) and our total (19).
Let's create a ratio.
12:19
This ratio cannot be simplified further, so that is your answer.
Hope this helps!
