Answer:
Multiply input by 4.
Step-by-step explanation:
So, all we have to do is find the difference between the input/output.
So for the first one.
4y=1x
Divde both sides:
1y=1/4x
Next we have 16y=4x
Divide both sides:
1y=1/4x
Ok, so we now know that y is 1/4x
Or in otherwords, 4x is 1y.
Remember x is input, and y is output.
So we can think of this as the input times 4 equals the output.
This seems to be the second answer.
Hope this helps!
Answer:
Second option: multiply input number by 4.
Step-by-step explanation:
You need to remember that the "input numbers" are the values of "x" and the "output numbers" are the values of "y".
You can observe in the table that each output number is always four time its corresponding input number. This means that to find the missing numbers on the given table, you need to multiply the corresponding input number by 4.
Therefore, you get:
For : x=3
y=4x
y=4(3)
y=12
For : x=6
y=4x
y=4(6)
y=24
Describe the shape of the data distribution.
Answer:
A.) negatively skewed
B.) Symmetric
C.) Positively skewed
Step-by-step explanation:
The shape of a distribution can be described in terms of the tail and peak of the distribution as Symmetric, left tailed or right tailed.
In the first graph; distribution is left tailed as we have a longer tail to the left Than to the right side of the distribution and the peak Hence, slightly shifting to the right.
The second graph on the other hand sees the peak being centered, at the centre of the distribution and the tails being even. Hence, we have a Symmetric or normal distribution.
The third is the opposite of the first with the tail being to the right and peak slightly shifting to the left to give a positive skew or right tailed distribution.
Jim Clinnin purchased a used RV with 18,500 miles for $46,400. originally the RV sold for $67,500 with a residual value of $19,500. After subtracting the residual value, depreciation allowance per mile was $0.79. How much was Jim's purchase price over or below the book value?( input the amount as positive value.)
Answer:
Jim bought the used RV at a price of $ 6,485 under its book price.
Step-by-step explanation:
Given that Jim Clinnin purchased a used RV with 18,500 miles for $ 46,400, and originally the RV sold for $ 67,500 with a residual value of $ 19,500 and, after subtracting the residual value, depreciation allowance per mile was $ 0.79, to determine how much was Jim's purchase price over or below the book value the following calculation must be performed:
18,500 x 0.79 = 14615
67,500 - 14,615 = X
52.885 = X
52,885 - 46,400 = 6,485
Therefore, Jim bought the used RV at a price of $ 6,485 under its book price.

Answer:
Your answer for both is 31 degrees
Step-by-step explanation:
Because they are similar we know their angles are the same. If you know the rule about triangles' interior angles always add up to 180, then you can just easily find this out.
First you do
82+67 = 149
Take that answer and minus it by 180
180-149 = 31
Answer:
*Using < for angle symbol*
m<E= 61 degrees
m<G= 119 degrees
Step-by-step explanation:
Because the two triangles are similar (meaning they have either length of sides or angle measurements in common, we can assume that they have the same angles because they are not the same size. We know that m<A= 82 degrees, which means so will m<D. You add the 82 and the 37 (from m<F) together to find 119. You subtract this from 180 (the total angle measurement of a triangle) to find m<E= 61. To find m<G, you subtract the 61 from 180, the angle measurement of a straight line, to find 119.
Hope this helps! Have a nice day :)
Cassie rolls a fair number cube with 6 faces labeled 1 through 6. She rolls the number cube 300 times. Which results are
probable to happen according to theoretical probability? Select TWO answers.
On solving the question, we can say that - the probability of given will be P(a/c) = 3/6 = 1/2
What is probability?A branch of mathematics known as probability measures the possibility of an event happening or a proposition being true. The probability of an occurrence is a number between 0 and 1, where roughly 0 denotes the event's improbability and 1 denotes certainty. A probability is a numerical representation of the possibility or probability that a specific event will take place. Probabilities can alternatively be stated as percentages ranging from 0% to 100%, or as percentages from 0 to 1. the proportion between the number of events in a comprehensive collection of equally likely outcomes that lead to a certain occurrence and the entire number of outcomes.
here,
the probability that event the dice will roll is 6
and chances of geting even numbers are = 3
so P(a/c) = 3/6 = 1/2

5x -2y = 1, 5x -6y = b
what is the value of b so that it has no solution
Answer:
DNE
Step-by-step explanation:
You want the value of 'b' so that the system of equations has no solution.
5x -2y = 15x -6y = bNo solutionIn order for the system of two linear equations to have no solution, the equations must describe parallel lines. That is, the lines must have the same slope.
SlopeThe slope of the line written in the form px -qy = c is the coefficient of x when the equation is rearranged to "y=" form. Here, that is p/q.
The slope of the first line is 5/2; the slope of the second line is 5/6. These values are different and do not depend on 'b'.
There is no value of 'b' that will make this system have no solution. It does not exist (DNE).

The sides of a square are 7 inches long. Enter the length of the diagonal of the square to the nearest tenth.
Answer:
9.9 inches
Step-by-step explanation:
Use the pythagorean Theorem
c^2 = a^2 + b^2
c^2 = 7^2 + 7^2
c^2 = 49 + 49
c^2 = 98
Take the square root of both sides
c = 9.8994949366

Maya went shopping for a new video game because of a sale. The store was offering a 40% discount. If the price on the tag was pp, which expression does NOT represent the price after the discount but before tax?
The expression that represents the price of the video game after the discount is
p - 0.4p
Where p is the original price of the video game.
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Price of the video game = p
Discount = 40%
The price of the video game after the discount.
= p - (40% of p)
= p - (40/100)p
= p - 0.4p
Thus,
The expression is p - 0.4p.
