Answer:

Five and twenty six twenty eighths.

Step-by-step explanation:

Start with writing the fractions in numbers:

\(2\frac{3}{7} +3\frac{2}{4}\)

The 2 next to the first fraction is considered a whole number therefore we can say:

\(\frac{2}{1} *\frac{7}{7} =\frac{14}{7}\) then,  \(\frac{14}{7} + \frac{3}{7} =\frac{17}{7}\)

\(2\frac{3}{7} =\frac{17}{7}\)

The 3 is also considered a whole number therefore:

\(\frac{3}{1} *\frac{4}{4} =\frac{12}{4}\) then, \(\frac{12}{4} +\frac{2}{4} =\frac{14}{4}\)

\(3\frac{2}{4} =\frac{14}{4}\)

We got our 2 fractions without whole numbers now which makes it easier to add them up however they have different denominators meaning we can't add them.

\(\frac{17}{7} +\frac{14}{4}\) not possible to add up.

We have to find a common factor, we will do this by looking at our times tables and realizing that 7x4= 28 and 4*7= 28. This will ensure both dominators are the same.

\(\frac{17}{7} *\frac{4}{4} =\frac{68}{28}\)

\(\frac{14}{4} *\frac{7}{7} =\frac{98}{28}\)

Now we got both fractions with equal denominators which means we can add them up as you would with normal numbers:

\(\frac{68}{28} +\frac{98}{28} =\frac{166}{28}\)

We need to make sure to simplify the resultant fraction now, we know that 28*5= 140 and 28*6= 168, we will use 5 as our whole unit since it fits (168 is greater than 166 therefore we can't use that):

\(\frac{166}{28} =5\frac{26}{28}\) (this is the answer on the answer choices)

Now just simplify 26 over 28:

\(5\frac{26}{28}=5\frac{13}{14}\)

This gives us our final answer of 5 and thirteen fourteenths however judging from the answer choices our answer will be five and twenty six twenty eighths.

 The equation for the tangent plane to the surface z = 2y² - 2x² at the point P(ro, yo, zo) = (1, 1, 1) on the surface is z = 4x + 4y - 4.

To find the equation for the tangent plane at point P(1, 1, 1), we need to determine the normal vector to the surface at that point. The normal vector is perpendicular to  tangent plane and provides the direction of the normal to the surface.
First, we find the partial derivatives of the surface equation with respect to x and y:
∂z/∂x = -4x
∂z/∂y = 4yAt the point P(1, 1, 1), plugging in the values gives:
∂z/∂x = -4(1) = -4
∂z/∂y = 4(1) = 4
The normal vector is obtained by taking the negative of the coefficients of x, y, and z in the partial derivatives:
N = (-∂z/∂x, -∂z/∂y, 1) = (4, -4, 1)
Using the normal vector and the point P(1, 1, 1), we can write the equation for the tangent plane in the point-normal form:
4(x - 1) - 4(y - 1) + (z - 1) = 0
Simplifying, we get:4x - 4y + z - 4 = 0
Rearranging the terms, we obtain the equation for the tangent plane as:
z = 4x + 4y - 4
Therefore, the equation for the tangent plane to the surface z = 2y² - 2x² at the point P(1, 1, 1) on the surface is z = 4x + 4y - 4.

The mean of the numbers in Table 8.10 is 5.2.The median of the numbers in Table 8.10 is 5.The mode of the numbers in Table 8.10 is 5

The measures of central tendency are statistical tools used to find the “center” or average of a given set of data. The three main measures of central tendency: mean, median and mode.

The mean is known as the average of a set of numbers. To calculate the mean of the numbers given in Table 8.10, add up all of the numbers (2 + 3 + 1 + 5 + 9 + 4 + 5 + 6 + 8 + 7 + 11) and divide by the total number of rolls (50). The mean of the numbers in Table 8.10 is 5.2.

The median is considered as the middle number of a set of numbers arranged in numerical order. To find the median of the numbers in Table 8.10, first arrange the numbers in numerical order (1, 2, 3, 4, 5, 5, 6, 7, 8, 9, 11) and then find the middle number. The median of the numbers in Table 8.10 is 5.

The mode is considered as the number that appears the most often in a set of numbers. The mode of the numbers in Table 8.10 is 5, since it appears twice, while the other numbers appear only once.

Answer:

9m

Step-by-step explanation:

Based on the graph, the slope of this line is equal to 2/3.

In Mathematics, the slope of any straight line can be determined by using this mathematical equation;

Slope (m) = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Based on the information provided in the graph, we can logically deduce the following data points on the line:

Points on x-axis = (2, 5).

Points on y-axis = (6, 8).

Substituting the given data points into the slope formula, we have the following;

Slope, m = (y₂ - y₁)/(x₂ - x₁)

Slope, m = (8 - 6)/(5 - 2)

Slope, m = 2/3.

Answer:

\(\frac{1}{2}(4x + \frac{2}{5} ) = \frac{4}{5}\\2x + \frac{1}{5} = \frac{4}{5}\\\frac{10x + 1}{5} = \frac{4}{5}\\10x + 1= 4\\10x = 3\\x = \frac{3}{10}\)

Answer:

x = 3/10

Step-by-step explanation:

Given equation,

→ 1/2(4x + 2/5) = 4/5

Let's solve the problem,

→ 1/2(4x + 2/5) = 4/5

→ 2x + (1/5) = 4/5

→ 2x = (4/5) - (1/5)

→ x = (3/5) × (1/2)

→ [ x = 3/10 ]

Thus, the value is 3/10.

The 125 feet long line and the angles 65°10', and 60°10' obtained from the surveying equipment gives the length of the bridge as approximately 1234.2 feet.

Given;

Location of the tree = The other side of the river from the surveyor

Length of the line measured along the river, L = 125 feet

Angle to the tree from the start of the line = 65°10'

1° = 60'

10' = ((1/60)×10)° = (1/6)°

65°10' = (65 + 10/60)° = (65 + 1/6)°

Angle measured at the end of the line, E = 60°10'

Similarly;

E = 60°10' = (60 + 1/6)°

The interior angle, S, of the triangle formed by the tree and the line, at the start of the line is therefore;

Angle S = 180° - (65 + 1/6)° = (114+5/6)° (linear pair angles)

S = (114+5/6)°

From the angle sum property of a triangle, angle formed at the tree, T, is therefore;

T = 180° - ((114+5/6)° + (60 + 1/6)°) = 5°

According to the rule of sines, we have;

l/(sin T) = b/(sin E)

Where;

b = The length of the bridge

Which gives;

124/(sin 5°) = b/(sin (60 + 1/6)°)

b = (sin (60 + 1/6)°) × (124/(sin 5°)) ≈ 1234.2

When raw scores from normal distribution are converted to standard scores, the resulting distribution has a mean equal to 0 and SD equal to 1.

A standard score (also known as a z-score) represents the number of standard deviations from the mean a data point is.

Standard scores, which are typically found for normally distributed data, are used in statistics to compare an observation to the population mean and standard deviation, and they can be used to identify how unusual or common a particular value is. The formula for calculating standard scores is as follows:

z = (X - μ) / σ

Where: X is the raw score

μ is the population mean

σ is the population standard deviation

For normally distributed data, the resulting distribution has a mean equal to 0 and a standard deviation (SD) equal to 1.

Therefore, when converting raw scores from a normal distribution to standard scores, one can find the number of standard deviations a score is above or below the mean of the distribution.

(-1,8)

Step-by-step explanation:

The easiest method would be using substitution:

\(\left \{ {{-10x+3y=34} \atop {y = -8x}} \right.\)

Substitute the second equation into the first one:

\(-10x + 3(-8x)=34\)

\(-10x+-24x = 34\)

\(-34x = 34\)

\(x = -1\)

Use the x-value to get the y-value:

\(y = -8*-1\)

\(y = 8\)

Final answer:

(-1,8)

Explanation:

We can use the substitution method to solve this system.

First we clear y from the first equation:

Then we replace this expression into the second equation:

The solution is (5, 9)

angle DCF = angle DCE + angle ECF

angle DCF = 75° + 54°

angle DCF = 129°

Measure of < DCF is  \(129^{0}\).

A figure which is formed by two rays or lines that shares a common endpoint is called an angle.

According to the figure

< DCE = \(75^{0}\)

< ECF = \(54^{0}\)

Measure of < DCF = < DCE + < ECF

=  \(75^{0}\) +  \(54^{0}\)

= \(129^{0}\)

The statistic is 101 out of 152 (66.45%) which  the questionnaires returned from the 800 mailed support the enactment of a statewide smoking ban in all enclosed public places.

To calculate this statistic, I first found the total number of questionnaires returned, which was 152. I then found the number of questionnaires that supported the ban, which was 101. To calculate the percentage, I then divided the number of questionnaires that supported the ban (101) by the total number of questionnaires returned (152), which gave me the answer of 66.45%.
