Find the complex conjugate of 10+ 61.
a. -10 + 61
b. 10-61
C.-10-61
d. 6 - 107
Answer:
b. 10 - 61
Step-by-step explanation:
10 + 61 is 71
We need to change the addition sign to subtraction.
10 - 61= -51
We need to find an equation that is equal to -51.
a. -10 +61
That equals 51, which is not 71, which means it is not letter a.
b. 10 - 61
That equals -51, which is not 71, which means it is not letter b.
c. -10 - 61
That equals -71, which is not 71, which means it is not letter c.
d. 6- 107
That equals -101, which is not 71, which means it is not letter d.
Solve 7x - 8(2x - 3) + 2 = 8 *
Answer:
Step-by-step explanation:
7x - 8(2x - 3) + 2 = 8
Expand bracket and Minus 2 on both sides
7x - 16x + 24 = 6
Minus 24 on both sides, and simplify the "x's"
-9x = -18
Divide by -9 on both sides
x = 2

Sam wants to write an equation to represent a
proportional relationship with a constant of proportionali
of 6. He writes the equation y = 6 + X.
Is he correct. If not, what is the correct equation? Explai
your answer. Consider the graph of the equation in your
response
Answer:
No, Sam is not correct. The graph of a proportional relationship has the form y = kx, where k is the constant of proportionality. Sam added the constant of proportionality instead of using it as the coefficient of x. The correct equation is y = 6x. Sam’s graph would be a straight line, but it would not pass through the origin.

Ralph chase plans to sell a piece of property for $145000. He wants the money to be paid off in two ways a short term note at 11% interest and a long term note at 8% interest. Find the amount of each note if the total annual interest paid is $13850.
Given :
Price of property , P = $145000 .
Money paid off in two ways a short term note at 11% interest and a long term note at 8% interest.
Total interest , I = $13850 .
To Find :
The amount of each note .
Solution :
Let , x money is paid off in 11 % interest rate and ( 145000-x) in 8% interest rate.
Therefore , their sum of interest in mathematics is given by :
[tex]\dfrac{11x}{100}+\dfrac{8(145000-x)}{100}=13850\\\\11x+1160000-8x=1385000\\\\3x=225000\\\\x=\$75000[/tex]
Therefore , the amount of note is $75000 and $70000 for 11% and 8% interest rate respectively .
Hence , this is the required solution .
Rearange the equation so n is the independent variable m+1=-2n+6 ? M= what
Answer:
m = - 2n + 5
Step-by-step explanation:
Given the equation:
m+1=-2n+6
Rearrange the equation so that n is the independent variable
The independent variable is the predictor variable, Hence causes a change in the value of predicted variable obtained.
m+1=-2n+6
m = - 2n + 6 - 1
m = - 2n + 5
m = - 2n + 5
The general form of a regression equation:
y = ax + b
Where y = dependent variable
x = independent variable ; a = Coefficient of slope ; b = intercept
Hence, the equation : m = - 2n + 5

Step-by-step explanation:
3x+4=7x-4
add 7x to each side of equation 4x+3x+-7x=-4x+7x+-7x
combine like terms 7x+-7x=0
4+ -4x =-4 +0

how are rates and unit rates different?
Answer:
down bellow
Step-by-step explanation:
A rate is a special ratio in which the two terms are in different units. For example, if a 12-ounce can of corn costs 69¢, the rate is 69¢ for 12 ounces. ... When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates.
Plot -1/4 on the horizontal and vertical number lines.
On the vertical number line, negative numbers are to the bottom of 0. Therefore, -1/4 will go one unit down from 0.
On the horizontal number line, negative numbers are to the left of 0. Therefore, -1/4 will go to the left one unit.

Step-by-step explanation:

y = x -1, if x = (-3,-1)y = -3x + 9, if x = [2, 4)2. f(x) = |4x + 36|

Express the set using the roster method.
{x | XEN and 15 sxs 50}
Choose the correct answer below.
A. {15, 16, 17, 18, ..., 50}
B {16, 17, 18, 19, ..., 50)
C. Ø
D. {..., 12, 13, 14, 51, 52, 53, ...}
I think you meant to write [tex]\{x | x \in \mathbb{N} \text{ and } 15 \le x \le 50\}[/tex]
If so, then the answer is Choice A. {15, 16, 17, 18, ..., 50}
We simply list every natural number from 15 to 50, including both endpoints. The three dots mean "continue this pattern". This way we don't literally have to write out every single value (there are 50-15+1 = 36 values in this set).
Note: the set of natural numbers is {1,2,3,...} so a natural number is basically a whole number, but 0 is not included. Negative values aren't included either.
According to a study done by a university student, the probability a randomly selected individual will not cover his or her mouth when sneezing is 0.267. Suppose you sit on a bench in a mall and observe people's habits as they sneeze.
A) What is the probability that among 12 randomly observed individuals exactly 8 do not cover their mouth when sneezing?
B) What is the probability that among 12 randomly observed individuals fewer than 5 do not cover their mouth when sneezing?(
C) Would you be surprised if, after observing 12 individuals, fewer than half covered their mouth when sneezing? Why?
Answer:
A
[tex]P(X = 8 ) = 0.0037[/tex]
B
[tex]P(X < 5) = 0.805[/tex]
C
I will not be surprised because the probability that fewer than half covered their mouth when sneezing is less than 0.5
Step-by-step explanation:
From the question we are told that
The probability a randomly selected individual will not cover his or her mouth when sneezing is [tex]p = 0.267[/tex]
The probability a randomly selected individual will cover his or her mouth when sneezing is
[tex]q = 1 -p[/tex]
[tex]q = 1 -0.267[/tex]
[tex]q = 0.733[/tex]
Generally the probability that among 12 randomly observed individuals exactly 8 do not cover their mouth when sneezing is mathematically represented as
[tex]P(X = 8 ) = \left 12 } \atop {}} \right. C_8 * p^8 * q^{12-8}[/tex]
[tex]P(X = 8 ) = 495 * (0.267)^8 * (0.733)^{12-8}[/tex]
[tex]P(X = 8 ) = 0.0037[/tex]
Generally the probability that among 12 randomly observed individuals fewer than 5 do not cover their mouth when sneezing is mathematically represented as
[tex]P(X < 5 ) = P[ P(X = 0) + \cdots + P(X = 4)][/tex]
=> [tex]P(X < 5) = \left 12 } \atop {}} \right. C_0 * (0.267)^0 * (0.733)^{(12- 0) }+\cdots + \left 12 } \atop {}} \right. C_4 * (0.267)^0 * (0.733)^{(12- 4) }[/tex]
=> [tex]P(X < 5) = 0.805[/tex]
Give that half of 12 is 6 then
The probability that fewer than half covered their mouth when sneezing is mathematically represented as
[tex]P(X > 6) = 1 - P( X \le 6 )[/tex]
=> [tex]P(X > 6) = 1 - [P(X = 0 ) +\cdots+P(X = 6) ][/tex]
=> [tex]P(X > 6) = 1 - [\left 12 } \atop {}} \right. C_0 *(0.267)^0 * (0.733)^{12 - 0 } +\cdots + \left 12 } \atop {}} \right. C_6 * (0.267)^6 * (0.733)^{12-6}][/tex]
=> [tex]P(X > 6) = 0.0206[/tex]
