Fractions are parts of a number. Decimals are fractions whose denominators are powers of 10. Percents are numbers out of 100. Therefore, you convert a fraction to a decimal, follow these steps:

\(3\frac{1}{4} = \frac{13}{4} = \frac{325}{100}\)

\(\frac{325}{100}\) = 3.25

3.25 × 100 = 325%

Explanation:

The data from the stem-and-leaf plot is:

10,

24,25,26,

30,30,32,33,

40,45,46

Add up those values

10+24+25+26+30+30+32+33+40+45+46 = 341

Then divide over n = 11 which is the sample size.

341/11 = 31 is the arithmetic mean.

Answer:

341/11 = 31 is the arithmetic mean.

Answer:

\(\sf N = \boxed{-2}\;M + \boxed{110}\)

Step-by-step explanation:

A trend line, also known as a line of best fit or regression line, is a straight or curved line that represents the general direction or pattern of a set of data points in a scatter plot or graph.

Trendlines are commonly used to identify patterns, make predictions, and understand the overall behavior of a dataset, and provide a visual representation of the underlying trend in the data.

The independent variable of a scatter plot is always drawn along the horizontal axis. The dependent variable of a scatter plot is always drawn along the vertical axis.

The trend line in the given scatter plot is a straight line with a negative slope. It shows the relationship between the variables M and N.

The trend line crosses the y-axis at (0, 110) and crosses the x-axis at (55, 0).

To find the slope of the trend line, substitute the two points on the line into the slope formula:

\(\textsf{Slope $(m)$}=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{0-110}{55-0}=\dfrac{-100}{55}=-2\)

Substitute the found slope, m = -2, and the y-intercept, b = 110, into the slope-intercept formula, y = mx + b:

\(y=-2x+110\)

As variable M is the independent variable, substitute x = M.

As variable N is the dependent variable, substitute y = N.

Therefore, the equation of the given trend line is:

\(\boxed{\sf N=-2M+110}\)

Answer:

x = - 26

Step-by-step explanation:

2x - 11 - 3x = 15

- x - 11 = 15

- x = 15 + 11

- x = 26

x = - 26

Answer: x = -26

Step-by-step explanation:

How to solve your problem

2x-11-3x=15

Solve

1

Combine like terms

2x - 11 3x +15

-x -11 = 15

Add

11

to both sides

-x-11=15

-x-11+11 = 15 + 11

Add the numbers

Answer:

Step-by-step explanation:

Let's start by finding the sum of the list of nine numbers, which we can then use to find the value of the remaining two numbers in the list:

Sum of the nine numbers = mean * number of numbers = 17 * 9 = 153

Let the three modes be a, b, and c. Since they are modes, each of them must appear at least twice in the list.

Let's assume that the numbers in the list are arranged in non-decreasing order. Then we have:

a ≤ b ≤ c

Since a, b, and c are modes, each of them must appear at least twice in the list. We have three cases to consider:

Case 1: Each of a, b, and c appears exactly twice in the list.

In this case, the remaining three numbers in the list are:

x1 = a + 4

x2 = b + 1

x3 = c - 8

We know that x1, x2, and x3 are distinct and not modes of the list. Therefore, they must be among the six numbers in the list that are not equal to a, b, or c. Let's call these numbers d, e, and f, where:

d ≤ e ≤ f

Then we have:

a + b + c + x1 + x2 + x3 + d + e + f = 153

3(a + b + c) + 3(d + e + f) = 153 + x1 + x2 + x3

Since x1, x2, and x3 are distinct and not modes of the list, we have:

x1 > c

x2 > b

x3 < c

Therefore, we can write:

x1 = c + k1

x2 = b + k2

x3 = a + k3

where k1, k2, and k3 are positive integers.

Substituting these expressions into the equation above, we get:

3(a + b + c) + 3(d + e + f) = 153 + a + b + c + k1 + k2 + k3

Simplifying, we get:

2(a + b + c) + 3(d + e + f) = 153 + k1 + k2 + k3

Since k1, k2, and k3 are positive integers, the right-hand side of this equation is at least 3. Therefore, we have:

2(a + b + c) + 3(d + e + f) ≥ 156

We want to find the value of 3(a + b + c), so let's isolate this term:

3(a + b + c) = 2(a + b + c) + (a + b + c)

Since the left-hand side is three times the sum of a, b, and c, and the right-hand side involves the sum of a, b, c, d, e, and f, we need to express d, e, and f in terms of a, b, and c.

From the inequality a ≤ b ≤ c, we have:

a + k3 ≤ b + k2 ≤ c + k1

Adding 4 to the first inequality, we get:

a + k3 + 4 ≤ b + k2 + 4 ≤ c + k1 + 4

Adding -8 to the second inequality, we get:

a + k3 + 4 ≤ c + k1 - 4 ≤ b + k2

Therefore, we can choose d = a + k3 + 4, e = c + k1 - 4, and f = b + k2. Then

An open circle is used to graph strict inequalities, which means the inequality does not include the value at the boundary. The inequalities that would have an open circle when graphed are:

x > 5.4

One-half less-than x

x > 0

This is a system of three equations with two unknowns, x and y. To solve it, we can use the method of elimination. First, we can eliminate y by subtracting the first equation from the second equation:

x^2-2y=3 - (x-2y=3) => x^2-x=0

Then we can factor the resulting equation and find the values of x:

x^2-x=0 => x(x-1)=0 => x=0 or x=1

Next, we can substitute these values of x into any of the original equations and find the corresponding values of y. For example, using the first equation:

x-2y=3 => 0-2y=3 => y=-3/2 when x=0 x-2y=3 => 1-2y=3 => y=-1 when x=1

Finally, we can substitute these values of x and y into the expression x2y-2xy2 and evaluate it:

x2y-2xy2 => 02(-3/2)-2(0)(-3/2)2 => 0 when x=0 and y=-3/2 x2y-2xy2 => 12(-1)-2(1)(-1)2 => -3 when x=1 and y=-1

Therefore, the value of x2y-2xy2 can be either 0 or -3 depending on the values of x and y.

Step-by-step explanation:

quadratic equation normally comes with squares

Answer:

40.5 inches

Step-by-step explanation:

I’m not sure if this is correct or not but my thinking is that you just add 26.9, 8.5, and 5.1 together since it says “How much more snow fell in the one day storm in 2006 than normal falls in February and March combined?” And combined basically means all together.

Answer: 13.3 more inches of snow fell in one day storm than normally falls in February and March combined.

February and March combined: 8.5+5.1 = 13.6

Since the question asked how much more, that means you subtract:

26.9 - 13.6 = 13.3

Answer:

1,530\(cm^{3}\)

Step-by-step explanation:

The formula to find a the volume of a rectangular prism :

Volume (V) = length x height x width

Your image has two rectangular prism put together

First rectangular prism (on the left):

Volume (V) = length x height x width

length = 10cm

width = 9cm

height = 9cm

Volume (V) = 10cm x 9cm x 9cm

Volume (V) = 810\(cm^{2}\)

Second rectangular prism (on the right):

Volume (V) = length x height x width

length = 18cm

width = 10cm

height = 4cm

Volume (V) = 18cm x 10cm x 4cm

Volume (V) = 720\(cm^{2}\)

Now to get the total of the figure.

Add both the first and second rectangular prism volume:

Volume (V) = 810\(cm^{2}\)

Volume (V) = 720\(cm^{2}\)

720 + 810 = 1530

Volume of the left cuboid

Volume of the right cuboid
