Answer: 1.26 is the single decimal multiplier.Oct 7, 2019
Somewhere around in briany there was i think smilier or the same question this so this might aswell e the answer.
Step-by-step explanation:
Use the given values of n and p to find the minimum usual value μ − 2σ and the
maximum usual value μ + 2σ. Round your answer to the nearest hundredth unless
otherwise noted.
n = 261, p =1/5
Minimum: 65.12; maximum: 39.28
Minimum: 39.28; maximum: 65.12
Minimum: 45.74; maximum: 58.66
Minimum: 43.06; maximum: 61.34
After answering the question provided, we can predict that the result will be as by equation As a result, the correct response is: Minimum: 41.64; Maximum: 62.76.
What is equation?A mathematical equation is a process that links two statements and indicates equality using the equals sign (=). A mathematical statement that proves the equality of two mathematical expressions is known as an equation in algebra. For instance, the equal sign separates the numbers 3x + 5 and 14 in the equation 3x + 5 = 14. A mathematical formula may be used to understand the link between the two sentences that are written on opposite sides of a letter. Frequently, the logo and the particular software are identical. like in 2x - 4 = 2, for example.
A binomial distribution with the specified values of n and p has a mean of = np and a standard deviation of = sqrt(np(1-p)).
Inputting n = 261 and p = 1/5 results in:
μ = np = 261 × 1/5 = 52.2
5.28 is equal to sqrt(np(1-p)) = sqrt(261 1/5 4/5)
Calculating the minimal typical value of 2 is as follows:
μ − 2σ = 52.2 − 2 × 5.28 ≈ 41.64
The calculation for the maximum typical value + 2 is as follows:
μ + 2σ = 52.2 + 2 × 5.28 ≈ 62.76
These values are rounded to the nearest hundredth, giving us:
The range is 41.64 to 62.76.
As a result, the correct response is: Minimum: 41.64; Maximum: 62.76.

The sum of a number, n, and 8 is multiplied by -4, and the result is -12.
What is the number? pls hlp you'll get 12 points
n = -5
n = 1
n = 5
n = 11
- 4 × ( n + 8 ) = - 12
Divide both sides by - 4
( - 4 × ( n + 8 ) ) ÷ ( - 4 ) = - 12 ÷ ( - 4 )
Simplification
( n + 8 ) = 3
n + 8 = 3
Subtract both sides - 8
n + 8 - 8 = 3 - 8
n = - 5
The ramp on the back of a moving van is 7 ft high and rises at an angle of 28°. How long is the ramp? Round to the nearest foot.
Answer:
6 feets
Step-by-step explanation:
Height of ramp = 7feets
θ = 28°
Length of ramp = x
Using trigonometric relation :
Sin θ = opposite / hypotenus
Sin 28 = 3 / x
0.4694715 = 3 / x
0.4694715x = 3
x = 3 / 0.4694715
x = 6.39 feets
The length of the ramp = 6 feets

find the inverse of f(x)= 2x/(5x+6)
Answer:
[tex]f(x) = \frac{2x}{5y+6}[/tex]
Step-by-step explanation:
Answer:
Below!
Step-by-step explanation:
f(x) = 2x/5x+6
Sub y for f(x) : y = 2x/5x+6
Swap x and y : x = 2y/5y+6
Multiply both sides by 5y+6 : 2y = (5y + 6) x
Distribute x : 2y = 5xy + 6x
Change sign : 2y - 5xy = 6x
Factor out y : (2-5x)y = 6x
Divide both sides by 2-5x : y = 6x/2-5x
Substitute for y : f^-1(x) = 6x/2-5x
Answer: f^-1(x) = 6x/2-5x

Fiona salary is $21000, and she excepts to receive a 3% raise each year; 8 years. The function is y= Her salary after 8 years is $=
Answer:
her salary after 8 years is $26,602
Step-by-step explanation:
Given that
Fiona salary is $21,000
She received 3% raise each year
We need to find her salary after 8 years
So, here we apply the future value formula
i.e.
= Present value × (1 + rate of interest)^number of years
= $21,000 × (1 + 0.03)^8
= $21,000 × 1.03^8
= $26,602
hence, her salary after 8 years is $26,602

Answer:
arc BD = 148°
Step-by-step explanation:
The arc BC is twice the inscribed angle BDC
arc BC = 2 × 56° = 112°
The 3 arcs sum to 360° , then
arc BD = 360° - (100 + 112)° = 360° - 212° = 148°

The sum of the arithmetic series is:
893
What are arithmetic progressions?
An arithmetic sequence with a specific number of terms is the sum of all the terms in an arithmetic series.
An arithmetic sequence's first n terms are added together to form (n/2).(a1+an). The arithmetic series formula is what it is known as.
Solution:
Given:
a1 = 11, a2 = 15 and an=83
Step-1:
d= a2 ₋ a1
d= 4
Now, an = a ₊ (n ₋ 1)d
83 = a ₊ (n ₋ 1)4
83 = 11 ₊ 4n ₋4
83 = 7 ₊ 4n
4n = 83 ₋ 7
n = 19
Step-2:
Now, Sn = n/2 (a1 ₊ an)
Sn = 19/2 (11 ₊ 83)
Sn = 19/2 ₓ 94
Sn = 893
Hence we get the answer as 893

Tiys earns $7 an hour owing her neighbors lawn.
Part A: create two variables and determine which is dependent and which is independent for this situation.
Part B list three order pairs to show the values of the two variables.
Part C write and equation to represent the relationship between the two variables.
Answer:
Part A) The independent variable is the hours that Tiya mows her neighbor's lawn, and we can denote that with x. It's the variable that isn't affected by other factors. The dependent variable is the amount of money Tiya earns, which we can denote with y. The dependent variable is the variable that is affected by other factors. The amount of money Tiya makes depends on how many hours she works.
Part B) As stated in part A, x is the hours and y is the money earned. The ordered pairs are in (x, y) form, with x being the hours and y being the money earned. For example, if Tiya worked one hour, x would be 1. As she earns 7 dollars per hour, she would earn 7 dollars (1*7), which is y. Therefore, one ordered pair could be (1, 7). Two hours would give Tiya 14 dollars, so we have another pair of (2, 14). Three hours would give Tiya 21 dollars, so we have (3, 21). We can do that for any numbers.
Part C) With every hour, Tiya earns 7 dollars. In order to find y, which is the amount of money totally earned, we multiply x by 7 (7 dollars per hour). Therefore, y = 7x.

Which is a number that can be written as a fraction in the form a/b?
Answer:
Step-by-step explanation:
Rational numbers are the type of numbers that can be written in fraction forms (1/b where a and b are integers and b ≠ 0). Rational numbers also include decimals that are repetitive (0.313131313131) and decimals that end (0.25).
The opposite are irrational numbers that cannot be written in fraction forms and that include decimals that do not end or repeat (0.249654296432926....).
It is good to know a fraction with denomination equal to zero will give an undefined value.

The box plot shows the algebra scores of students in class A and class B.
The median score of class A is _____.
The interquartile range of class B is ____.
The difference of the medians of class A and class B is
the interquartile range of either data set.
Answer:
[tex]Mid(A) = 73[/tex]
[tex]IQR(B) = 8[/tex]
The difference of the medians of class A and class B is between the interquartile range of either data set.
Step-by-step explanation:
Given
The attached box plots
To answer this, see attached image for how to read a box plot
With reference to the attached image of how to read the box plot;
Solving (a): The median of class A
[tex]Mid(A) = 73[/tex]
Solving (b): IQR of class B
IQR is calculated as:
[tex]IQR =Q_3 - Q_1[/tex]
From the box plot of class B, we have:
[tex]Q_3 = 87[/tex]
[tex]Q_1 = 79[/tex]
So, we have:
[tex]IQR(B) = 87 - 79[/tex]
[tex]IQR(B) = 8[/tex]
Solving (c):
[tex]Mid(A) = 73[/tex]
[tex]Mid(B) = 82[/tex]
[tex]IQR(B) = 8[/tex]
IQR of class A is calculated as:
[tex]IQR =Q_3 - Q_1[/tex]
From the box plot of class A, we have:
[tex]Q_3 = 76[/tex]
[tex]Q_1 = 68[/tex]
So, we have:
[tex]IQR(A) = 78 - 68[/tex]
[tex]IQR(A) = 10[/tex]
The difference (d) between the medians is:
[tex]d =Mid(B) - Mid(A)[/tex]
[tex]d = 82 - 73[/tex]
[tex]d = 9[/tex]
From [tex]smallest[/tex] to [tex]largest[/tex], we have: 8, 9, 10
