Put x + 2y=4 into slope-intercept form? y=mx+b format
Answer:
[tex]y=-\frac{1}{2} x+2[/tex]
Step-by-step explanation:
1. First we want to get the y all by itself
So we would subtract x from both sides and get [tex]2y=-x+4[/tex]
2. Then we would divide 2 from both sides
Answer: [tex]y=-\frac{1}{2} x+2[/tex]
a survey of statistics students asked how much time they spent on a computer during a 24 hour period. The results of the survey are provided in the table. Identify the model class for the distribution.
Answer:
the answer is more than 241 because 0-60 minutes time 8 would be 480 but 241 time 2 is 482
The model class for the distribution is 0-60. Therefore, option A is the correct answer.
Given that, a survey of statistics students asked how much time they spent on a computer during a 24-hour period.
We need to identify the model class for the distribution.
What is the model class?The modal class is the class with the highest frequency. We know that the mode is the number or observation that most often appears. So, the modal class is the class in grouped data that contains the mode. That means the class that has the highest frequency is the modal class of the grouped data.
Now, from the given data table we can see the highest frequency is corresponding to the class 0-60.
The model class for the distribution is 0-60. Therefore, option A is the correct answer.

The numbers which are decimals by nature can be represented in the form of fractions. For example, 0.5 can also be written as 5/10. ... Percentages refer to decimal numbers to the base 100. These are represented by a % (percent sign).Since a percent is a ratio a ratio can be written as a fraction. This means any of these forms can be converted to any of the others.

40% of the 7920 visitors to an amusement park were children. 25% of these children and 1/3 of the adults were repeat visitors. How many percent of the visitors were visiting the amusement park for the first time?
Total number of visitors = 7920
Find the number of children:
Children = 40% of 7920
Children = 0.4 x 7920
Children = 3168
Find the number of adults:
Adult = 7920 - 3168 = 4752
Find the number of repeated visitors that are children:
Repeated visitors = 25% x 3168
Repeated visitors = 0.25 x 3168
Repeated visitors = 792
Find the number of children that are visiting for the first time:
First time visitors = 3168 - 792 = 2376
Find the number of repeated visitors that are adult:
Repeated visitors = 1/3 x 4752
Repeated visitors = 1584
Find the number of adults that are visiting for the first time:
First time visitors = 4752 - 1584 = 3168
Find the total number of first time visitors:
Total number of first time visitors = 3168 + 2376 = 5544
Answer: There are 5544 visitors that are visiting for the first time

Find the dimensions of a rectangle whose perimeter is 30 meters and whose area is 56 square meters.
Answer: 8 and 7
Step-by-step explanation:
8 multiplied by 7 equals 56
8+8+7+7 equals 30 which is the perimeter
:)
The dimensions of the rectangle whose perimeter is 30 meters and whose area is 56 square meters are 7 meters and 8 meters.
What do we mean by the area of a surface?The area of a surface is the total space occupied by the two-dimensional cross-section.
What do we mean by the perimeter of an object?The perimeter of an object is the total length of its boundary.
How do we solve the given question?We are asked to find the dimensions of a rectangle whose perimeter is 30 meters and whose area is 56 square meters.
Let the length and breadth of the rectangle be l meters and b meters respectively.
We know that,
Perimeter of a rectangle = 2(length + breadth) = 2(l + b)
∴ 30 = 2(l + b)
or, 2(l + b) = 30
or, l + b = 15
or, b = 15 - l ...(i)
We know that,
Area of a rectangle = length*breadth = l*b
∴ 56 = l*b
or, l*b = 56
Substituting the value of b = 15 - l from (i) in the above equation, we get:
l(15 - l) = 56
or, 15l - l² = 56
or, l² - 15l + 56 = 0
or, l² - 8l - 7l + 56 = 0
or, l(l - 8) -7(l - 8) = 0
or, (l - 7)(l - 8) = 0
By zero-product law,
Either l - 7 = 0 ⇒ l = 7
Or, l - 8 = 0 ⇒ l = 8.
Substituting these values of l in (i),
b = 15 - l
∴ Either, b = 15 - 7 = 8
Or, b = 15 - 8 = 7.
In both cases, the dimensions of the rectangle are 7, and 8.
∴ The dimensions of the rectangle whose perimeter is 30 meters and whose area is 56 square meters are 7 meters and 8 meters.

Elliott states that he absolute value and opposite of a number are the same thing. Is Elliott correct? Explain.
Answer:
Elliot is incorrect
Step-by-step explanation:
Let's take an example: 2
Absolute value of 2 = |2| = 2
But the opposite of 2 = -(2) = -2
But 2 ≠ 2, so Elliott is incorrect.
The opposite of a number changes the sign from - to +, or + to -. Absolute value changes the sign of a number from - to + and keeps + as +.
-Chetan K
Answer:
No
Step-by-step explanation:
The absolute value of a number is the distance from 0. Distance is always positive, so the absolute value of a number is that number but positive. Thus, the absolute value of |2| is still 2. However, the opposite of a number is that number on the opposite side of 0. Therefore, the opposite of 2 is -2. To find the opposite of a number just flip the sign.
So, these are different because the absolute value is always positive while the opposite can be either sign.
