Equation of the line is y = -3x + 7.
What are parallel line ?Two lines in the same plane that are equally spaced apart and never cross each other are said to be parallel lines.
Suppose the line's equation is y=mx + c, where m and c are unknowns.
Since it is parallel to the equation y = -3x + 4 and -3x - y = -4, its slope is now -3. So m = -3.
Additionally, point (1,4). Therefore, this should be satisfied by our line's equation.
Consequently, 4 = -3(1) + c
therefore c = 7
The line's equation changes to y = -3x + 7.

The prices paid for a model of a new car are approximately normally distributed with a mean of $17,000 and a standard deviation of $500.
The price that is 3 standard deviations above the mean is $_
The price that is 2 standard deviations below the mean is $_
The percentage of buyers who paid between $16,500 and $17,500 is %___
The percentage of buyers who paid between $17,000 and $18,000 is %___
The percentage of buyers who paid less than $16,000 is %__
Answer: If the prices paid for a model of a new car are approximately normally distributed with a mean of $17,000 and a standard deviation of $500, it means that the majority of the prices paid for the car will fall within a certain range around the mean. Specifically, approximately 68% of the prices paid will be within one standard deviation of the mean, which in this case would be between $16,500 and $17,500. Approximately 95% of the prices paid will be within two standard deviations of the mean, which would be between $16,000 and $18,000. And approximately 99.7% of the prices paid will be within three standard deviations of the mean, which would be between $15,500 and $18,500. This shows that the prices paid for the car are relatively consistent, with only a small percentage falling outside of the range determined by the mean and standard deviation.

Surface area implies the external surface that bounds a given shape. The surface area of the shape is 384 sq in.
The surface area of a shape is the external side of the shape that can be seen. Sometimes, a given shape may have different shapes that forms its surface area.
From the given question,
i. The area of triangular surface = 1/2 * base* height
= 1/2*12*8
= 48
Area of the triangular surface = 48 sq in.
ii. The area of its rectangular sides = length * width
= 9* 10
= 90
Area of its rectangular sides = 90 sq in.
iii. The area of its base = length * width
= 9 * 12
= 108
Area of its base = 108 sq in.
Therefore,
the surface area of the shape = (2*48) + (2*90) + 108
= 96 + 180 + 108
= 384 sq in.
The surface area of the given shape is 384 square inches.

HELPPPP!! how do i find the angle measure ?
Answer:
1. m<AOB = 50 degree
2. m<COD = 90 degree
3. m<BOD = 130 degree
4. m<AOD = 180 degree
Step-by-step explanation:
1. We see that <AOB has one leg at 0 and the other leg at 50 degrees, so the <AOB is 50 degrees.
2. We see that <COD has one leg at 0 and the other leg at 90 degrees, so the <COD is 90 degrees
3. We see that <BOD has one leg at 50 and the other leg at 180 leg, so the <BOD is 180 - 50 = 130 degree
4/ We see that <AOD has one leg at 0 and the other leg at 180 degrees, so the <AOD is 180 - 0 = 180 degrees
An airplane is descending from 35600 ft at 3200ft per mile,
how long would it be until the plane reaches 18,000 ft? I dont remember the exact ft but i just need a example such as a equation to solve please! please help! T>T
Answer:
To calculate how long it will take for the plane to reach 18,000 ft, first find the difference between the plane's current altitude and its target altitude:
35,600 ft - 18,000 ft = 17,600 ft
Then, divide this difference by the rate of descent to find the time it will take for the plane to reach its target altitude:
17,600 ft / 3,200 ft/mile = 5.5 miles
Since the rate of descent is given in feet per mile, this result is equivalent to the time it will take for the plane to reach its target altitude. Therefore, it will take the plane 5.5 miles (or a similar amount of time) to reach 18,000 ft.
Answer the questions about the following polynomial..... please help!
Answer:
x⁵ - 1/3x² -1
Step-by-step explanation:
In order to write polynomials in standard form:
1) Find the degree (power) of each term
2) Arrange them in descending order (largest to smallest)
We have : -1 + x⁵ - 1/3x²
The degree of -1 is 0 since there is no power.
The degree of x⁵ is 5.
The degree of - 1/3x² is 2.
Now arranging them in descending order:
x⁵ has the largest degree, followed by - 1/3x² and then -1, so the polynomial in standard form is:
x⁵ - 1/3x² -1

a) 4
b) 12
c) 48
d) 60
The instantaneous rate of change of f(x) = x³ − 5 at (2,3) is (b) 12
How to determine the instantaneous rate of changeFrom the question, we have the following parameters that can be used in our computation:
Function: f(x) = x³ − 5
Point = (2, 3)
Differentiate the function to get the instantaneous rate
This is represented as
f'(x) = 3x²
Substitute 2 for x in the equation
The 2 is coming from the x-coordinate in (2, 3)
So, we have
f'(2) = 3(2)²
Evaluate
f'(2) = 12
Hence, the instantaneous rate of change is 12

a fast-food restaurant runs a promotion in which certain food items come with game pieces. according to the restaurant, 1 in 4 game pieces is a winner. if jeff keeps playing until he wins a prize, what is the probability that he has to play the game exactly 5 times?
The probability that Jeff has to play the game exactly 5 times i.e he keeps playing until he wins prize is (0.25)⁵.
We have, a fast-food restaurant runs a promotion which consists some food items with games pieces. 1 in 4 game pieces is a winner. This means, probability of winning game or sucess (p) = 1/4 . Since number of trials is fixed, trials are independent and probability of success is constant in each trial, we can use Binomial distribution. The Binomial distribution probability formula is
P(X= x) = ⁿCₓ(p)ˣ(1-p)⁽ⁿ⁻ˣ⁾
where,n --> number of trials
p --> probability of success
x --> number of times for a specific outcome within n trials
ⁿCₓ --> number of combinations
we have calculate the probability that he has to play the game exactly 5 times, i.e
x = 5 . Jeff keeps playing until he wins and he wins when he play exactly 5 times so,n= 5
Now, plugging all known values in above formula we get,
P(X= 5) = ⁵C₅(0.25)⁵(1-0.25)⁰
=> P(X= 5) = ⁵C₅(0.25)⁵(0.75)⁰
=> P(X= 5) = 1× (0.25)⁵× 1 = (0.25)⁵

The probability that the deal of a five-card hand provides a pair of aces is 0.0399
In this question, we have been given a deck of playing cards contains 52 cards, four of which are aces.
We need to find the probability that the deal of a five-card hand provides a pair of aces.
The sample space for given experiment is: choosing 52 cars choosing 5.
n(S) = 52C_5
We need to find the chance of getting a pair of aces, there are 4 aces in the pack on 2 of them.

So that means there are 48 cards left which are not aces in the pack and want 2 of those.
So, the required probability is:
P(A) = (4C_2 * 48C_3) / 52C_5
P(A) = (6 * 17296) /2598960
P(A) = 103776 / 2598960

if x^2 + y^2 = 289, find the value of dy/dt at (8,15)
Answer: a)
Step-by-step explanation:
To find [tex]\frac{dy}{dx}[/tex], we will have to use implicit differentiation, and because the base is [tex]dx[/tex], we will take the deriviative of both sides with respect to [tex]x[/tex].
To derive [tex]y[/tex] with respect to [tex]x[/tex], just derive the term with respect to y then multiply the term with [tex]\frac{dy}{dx}[/tex].
So [tex]\frac{d}{dx} x^{2}[/tex] is just [tex]2x[/tex], [tex]\frac{d}{dx} y^{2}[/tex] is [tex]2y \frac{dy}{dx}[/tex], and [tex]\frac{d}{dx} 289[/tex] is 0. Now substitue each term with it's deriviative.
[tex]2x + 2y \frac{dy}{dx} = 0[/tex]
Now, just solve for [tex]\frac{dy}{dx}[/tex] when [tex]x[/tex] is 8 and [tex]y[/tex] is 15
[tex]2(8) + 2(15)\frac{dy}{dx} = 0[/tex]
[tex]16 + 30\frac{dy}{dx} = 0[/tex]
[tex]\frac{dy}{dx} = \frac{-16}{30} = \frac{-8}{15}[/tex]

suppose one individual is randomly chosen. find the probability that this person has an iq greater than 95.
The probability that this person has an IQ greater than 95 =62.93%
What is probability?The area of mathematics known as probability is concerned with the outcomes of random events. Probability refers to a chance or potential for something to happen. It explains the likelihood that a specific event will take place.
We frequently say things like, "It will probably rain today," "He will probably pass the test, "There is very little chance of getting a storm tonight," and "Most likely the price of onions will increase once more." We substitute the word probability for all of the words chance, doubt, maybe, likely, etc. in these sentences.
In essence, probability is the ability to forecast an outcome based on the variety and quantity of potential outcomes or the analysis of historical data.
Let X be the IQ
IQ is normally distributed with a mean of 100 and a standard deviation of 15.
