Answer:
The slope of the perpendicular line to the line is
m = [tex]\frac{-1}{2}[/tex]
Step-by-step explanation:
Step(i):-
Given that the line y =f(x) = 2x +6
⇒ y = 2x +6
comparing y =mx +c
The slope of the given line m =2
Step(ii):-
The slope of the perpendicular line = [tex]\frac{-1}{m}[/tex]
The slope of the perpendicular line = [tex]\frac{-1}{2}[/tex]
On a scale drawing of a boat, 15 feet are represented by 10 inches. If the drawing was 8 inches long, how long was the boat?
Answer:
12 feet
Step-by-step explanation:
On a scale drawing of a boat, 15 feet are represented by 10 inches.
This means [tex]15\,\,feet=10\,\,inches[/tex]
[tex]1\,\,inch=\frac{15}{10}\,\,feet=\frac{3}{2}\,\,feet[/tex]
Now, find the length of the boat if the drawing was 8 inches long.
Length of the boat = [tex]8(\frac{3}{2})=12\,\,feets[/tex]
So, length of the boat is 12 feets if the drawing was 8 inches long.

In a large population, 60% of the people have been vaccinated. If 4 people are randomly selected, what is the probability that AT LEAST ONE of them has been vaccinated?
Give your answer as a decimal to 4 places.
Answer:
0.9744 probability that AT LEAST ONE of them has been vaccinated
Step-by-step explanation:
For each person, there are only two possible outcomes. Either they have been vaccinated, or they have not. The probability of a person having been vaccinated is independent of any other person. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
60% of the people have been vaccinated.
This means that [tex]p = 0.6[/tex]
If 4 people are randomly selected, what is the probability that AT LEAST ONE of them has been vaccinated?
This is
[tex]P(X \geq 1)[/tex] when [tex]n = 4[/tex].
We have that
[tex]P(X \geq 1) = 1 - P(X = 0)[/tex]
In which
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{4,0}.(0.6)^{0}.(0.4)^{4} = 0.0256[/tex]
[tex]P(X \geq 1) = 1 - P(X = 0) = 1 - 0.0256 = 0.9744[/tex]
0.9744 probability that AT LEAST ONE of them has been vaccinated

if f(x)= x/2-3 and g(x) = 2x^2+x-6, find (f+g)(x)
Answer:
2x² + 3x/2 - 9
Step-by-step explanation:
(f+g)(x) = f(x) + g(x)
= x/2 - 3 + 2x² + x - 6
= 2x² + x/2 + x -3 -6
= 2x² + 3x/2 - 9

What's the slope of a line that passes through (−12,15) and (0,4)?
Answer:
-11/12
Step-by-step explanation:
slope for points (x1,y1) and (x2,y2)
slope=(y2-y1)/(x2-x1)
(x,y)
(-12,15)
(0,4)
x1=-12
y1=15
x2=0
y2=4
slope=(4-15)/(0-(-12))=-11/(0+12)=-11/12
Answer:
Slope: -11/12x
Step-by-step explanation:
Slope-intercept equation:
y = mx + b
(m = slope)
The formula for slope is below.
m = [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]
With your two points, you can accurately determine your slope.
(-12, 15) (0,4)
x1 = -12
y1 = 15
x2 = 0
y2 = 4
Apply this information in the slope formula to get:
[tex]\frac{4 - 15}{0 - -12}[/tex]
Change the 0 - -12 to 0 + 12
[tex]\frac{4 - 15}{0 + 12}[/tex]
4 - 15 = -11
0 + 12 = 12
Place -11 and 12 into a fraction.
[tex]\frac{-11}{12}[/tex] OR -11/12
Add "x" to the end from "mx" within the slope-intercept equation
-11/12x

Use the diagram to complete the statements using correct notation. If there is not enough information to prove congruency, explain why:
Example cannot be determined
If it’s a congruent, the congruence reason has to be SAS SSS ASA OR SAA
Do not answer this with one answer ,blank, or a ridiculous answer.... this is serious please.
Answer:
Can not be determined.
Step-by-step explanation:
From the figure attached,
In ΔHFS and ΔIFS,
Side HS ≅ Side HI [Given]
∠HFS ≅ ∠IFS [Given]
Side FS ≅ Side FS [Reflexive property]
But there is no property of SSA (Side-side-angles for the congruence of two triangles)
Therefore, answer is "can not be determined".

[tex]\frac{1}{7}+\frac{1}{2}[/tex]
Least common multiple of 7 and 2 is 14. Convert [tex]\frac{1}{7} and \frac{1}{2}[/tex] to fractions with denominator 14.
[tex]\frac{2}{14} + \frac{7}{14}[/tex]
Since [tex]\frac{2}{14} + \frac{7}{14}[/tex] have the same denominator, add them by adding their numerators.

What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that,
In a bean bag toss game, players earn 2 points for each beanbag that lands on the game board and 5 points for each bean bag that lands in the hole.
Since, Roopesh dropped the bag on land for two times, and points for bag landing is 2.
Therefore, We get;
His score will be,
⇒ 2 × 2
or 2 + 2
Therefore, We get;
The correct expression which show the points Roopesh earns if two beanbags land on the board will be;
