There are ten bird baths in a park. On the first day of spring, the bird baths are filled. Several weeks later, the overall change in the water level is found. The results are shown in the table. What is the range of the data?
2.5
0.7
-2.2
2.1
2.3
-1.6
1.1
-2.4
2.7
1.2
Answer:
4.5
Step-by-step explanation:
The range of the given data would be 5.1 which is determined by the difference between the maximum value and the minimum value of data.
What is the range of data?The range of data is defined as a measure of the difference between the maximum value of data and the minimum value of data.
The given results data are as:
{ 2.5, 0.7, -2.2, 2.1, 2.3, -1.6, 1.1, -2.4, 2.7, 1.2 }
To determine the range of the data, we have to find the maximum value of the data and the minimum value of the data.
As per the given results,
The maximum value of data = 2.7
The minimum value of data = -2.4
So the range of the data would be:
⇒ the maximum value of the data - the minimum value of the data.
⇒ 2.7 - (-2.4)
⇒ 2.7 + 2.4
Apply the addition operation, and we get
⇒ 5.1
Therefore, the range of the given data would be 5.1.

Answer:
8.69>8.6
Step-by-step explanation:
Because 8.69 has .09 more than 8.6
Answer:
8.69 > 8.60
Step-by-step explanation:
You need to add a zero to the end to 8.6 so it's easier to compare. Since all the digits in the two numbers are the same except 9 and zero, those are what you need to compare. 9>0, so 8.69 > 8.6

write an equation of a line passing through point p(4, 0) that is parallel to the line -x+2y=12
Answer:
y = [tex]\frac{1}{2}[/tex]x - 2
Step-by-step explanation:
Given parameters:
Coordinates = p(4,0)
Equation of the line -x+2y=12
Solution:
A line parallel to the given line will have the same slope as it is;
-x+2y=12
2y = x + 12
y = [tex]\frac{1}{2}[/tex]x + [tex]\frac{12}{2}[/tex]
Since this conforms to y = mx + c where;
x and y are the coordinates
m is the slope
c is the intercept
Our slope is [tex]\frac{1}{2}[/tex]
The equation of the line is
y = mx + c
let us find c;
c = y - mx
c = 0 - ([tex]\frac{1}{2}[/tex] x 4)
c = -2
Now the equation of the line parallel to the line given is;
y = [tex]\frac{1}{2}[/tex]x - 2

John took 8 hours to drive 385 miles. He believes that at this same rate he will need at least 17 hours to drive 1000 miles which is the best estimate of the total amount of time he will need to drive 1000 miles
A- 17
B- 19
C-21
D-15
Answer:
Step-by-step explanation:
Step one:
give data
time= 8hours
distance=385mile
speed=?
Step two:
let us solve for the speed
Speed= distance/time
Speed=385/8
speed=48.125miles per hour
Step three:
let's find the time taken to cover 1000mile at the speed of 48.125 mi per hour
speed=distance/time
time=distance/speed
time=1000/48.125
time=20.779hours
approximately 21 hours

Dividing Fractions
The division of two fractions \frac{a}{b} and \frac{c}{d} is written as:
[tex]\displaystyle \frac{\frac{a}{b}}{ \frac{c}{d}}[/tex]
This division is usually easier done by multiplying the numerator by the reciprocal of the denominator:
[tex]\displaystyle \frac{\frac{a}{b}}{ \frac{c}{d}}=\frac{a}{b}\cdot \frac{c}{d}[/tex]
Jessie was dividing these two fractions:
[tex]\displaystyle \frac{\frac{1}{4}\ pounds}{ \frac{1}{8}\ quart}[/tex]
And got the incorrect result
[tex]\displaystyle \frac{1}{32}\ \text{ pound per quart}[/tex]
This mistake was probably the result of multiplying both fractions instead of dividing them.
The correct operation is:
[tex]\displaystyle \frac{\frac{1}{4}}{ \frac{1}{8}}=\frac{1}{4}\cdot \frac{8}{1}=\frac{8}{4}=2[/tex]
The correct result is 2 pounds per quart
Write the equation y=4x+9 in standard form using integers.
Answer:
[tex]4x-y=-9[/tex]
Step-by-step explanation:
The standard form of an equation is when both variables, x & y, are on the same side of the equation with a number on the other side.
To transform this equation from slope-intercept form to standard form, just switch sides for the y and the 9 like follows.
[tex]4x-y=-9[/tex]

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
The standard form of the equation y = 4x + 9 is
-4x + y = 9.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 3 = 2 is an equation.
2x + 4y + 4 is an equation.
We have,
y = 4x + 9
This is in the slope-intercept form of an equation.
The standard form of an equation is written as:
x + y = c
We need to keep the variable in the equation on one side and a constant on the other side of the equation
Now,
y = 4x + 9
Subtract 4x on both sides.
y - 4x = 4x + 9 -4x
y - 4x = 9
-4x + y = 9
This is in the form of a standard equation.
Thus,
The standard form of the equation y = 4x + 9 is
-4x + y = 9.

Step-by-step explanation:
Determine the height of the triangle if the area is 24 square inches and the base is 12 inches.
Answer:
4
Step-by-step explanation:
We use 1/2base times height to find the area and since we already have an area we just do 24= 6h then we divide 6 on both sides and height equals 4
Answer: 6 inches
Step 1: Subtract 12 because 12 iches is the base.
24 - 12 = 2
Step 2: Divide 12 by 2 because triangles have two equal sides.
12 ÷ 2 = 6

Find the value of each variable.
Answer:
19. x = 65
20. x = 12
21. x = 35, y = 85
Step-by-step explanation:
19. 2x -10 = 120
2x (-10 + 10) = (120 +10)
2x/2 = 130/2
x = 65
20. 2x + 4x + 108 = 180
6x + (108 - 108) = (180 - 108)
6x/6 = 72/6
x = 12
21. 2x + 25 = 3x - 10
2x + (25 - 25) = 3x (- 10 - 25)
(2x - 3x) = (3x - 3x) - 35
-x/-1 = -35/-1
x = 35
3x - 10 + y = 180
3(35) - 10 + y = 180
105 - 10 + y = 180
(95 - 95) + y = (180 - 95)
y = 85
Humans shed about three million particles of skin every five hours. Humans can shed about fifty thousand particles of skin every five minutes. The approximate number of particles of skin a human can shed in five hours can be written in the form a times 10^b, where a is 3 and b is __
Answer: The approximate number of particles of skin a human can shed in five hours can be written in the form a times 10^b, where a is 3 and b is 6 .
Step-by-step explanation:
Given: Humans shed about 3million particles of skin every 5 hours.
Since, 1 million = 1,000,000
Then 3 million = 3 x 1 million
[tex]= 3 \times1,000,000[/tex]
[tex]= 3,000,000[/tex]
[tex]=3\times10^6[/tex]
On comparing to [tex]a\times 10^{b}[/tex] , we get a = 3 and b=6
So, the approximate number of particles of skin a human can shed in five hours can be written in the form a times 10^b, where a is 3 and b is 6 .
Answer:
6
Step-by-step explanation:
First, write the approximate number of particles of skin a human can shed in five hours in scientific notation. This number is three million which can be written in the form a × 10b, where a is 3 and b is 6.

Can a decimal that has repeating digits after the decimal point be converted into a fraction? It depends on what the digits are that repeat. It depends on the number of digits that repeat. No, because the decimal is irrational, and no irrational numbers can be converted to fractions. Yes, because the decimal is rational, and all rational numbers can be converted to fractions.
Answer:
It depends on what digits repeat
Step-by-step explanation:
A decimal with repeating digits after the decimal point can be converted to a fraction depending on the digits after the decimal point.
For example, let’s have 4/3
When we evaluate this using a calculator, we can see that we have recurring 3 after the decimal point
So 4/3 is actually 1.3333333333333
We can see that based on the number after the decimal point we can convert this to 4/3
