Step-by-step explanation:

The LHS and RHS are exactly the same, so the equality is true.

The associate property of addition says that

[tex]\boxed{a+(b+c)=(a+b)+c}[/tex]

In order to make the addition of fractions, the denominators should be same. So we can write three fractions as one.

Answer:

23.2

Step-by-step explanation:

The sample standard deviation measures the spread of a data distribution of the sample. It is usually used to estimate the population standard deviation

23.2

The standard deviation of the given data set, with a mean of 40.06, is approximately 23.2 (rounded to the nearest tenth).

Option B is the correct answer.

We have,

Find the mean:

Mean = (11 + 16 + 22 + 28 + 29 + 30 + 31 + 34 + 37 + 38 + 43 + 49 + 56 + 78 + 99) / 15

= 601 / 15

= 40.06

Subtract the mean and square the differences:

(11 - 40.06)² = 844.48

(16 - 40.06)² = 578.8836

(22 - 40.06)² = 326.1636

(28 - 40.06)^² = 145.4436

(29 - 40.06)² = 122.3236

(30 - 40.06)² = 101.2036

(31 - 40.06)² = 82.0836

(34 - 40.06)² = 36.7236

(37 - 40.06)² = 9.3636

(38 - 40.06)² = 4.28

(43 - 40.06)² = 8.6436

(49 - 40.06)² = 79.92

(56 - 40.06)² = 254.0836

(78 - 40.06)² = 1439.4436

(99 - 40.06)² = 3473.9236

Calculate the mean of the squared differences:

The mean of squared differences.

= 7506.9632/15

= 500.4642

Take the square root of the mean squared differences:

Standard deviation = √(500.4642)

Standard deviation ≈ 23.223

Therefore,

The standard deviation of the given data set, with a mean of 40.06, is approximately 23.2.

Answer:

12

Step-by-step explanation:

14 doesn't go into both 48 and 84. 12 is the next highest and it goes into both of them.

[tex]33\frac{1}{3}[/tex]% of 36 is 12.

Percentage is the value per hundredth.This can be numerically expressed as (required percentage)/(100 percent)×total value = required value.We can also convert fractions and decimals into percentage by multiplying 100 with it.

According to the given question we have to determine [tex]33\frac{1}{3}[/tex] % is 12.

Let the required number be x.

∴[tex]33\frac{1}{3}[/tex] % of x is 12,This can be numerically written as

(100/3)/100×x = 12.

(1/3)x = 12.

x = 36.

To cross check what we can do is check what is [tex]33\frac{1}{3}[/tex] % of 36.

So, [tex]33\frac{1}{3}[/tex] is = 100/3.

(100/3)/100×36.

= 36/3.

= 12.

x = -3

base angle = 49 degrees

============================================

Work Shown:

The missing angle is (2x+55) degrees since the base angles are congruent.

Add up the three angles and set the sum equal to 180. Solve for x.

(82)+(2x+55)+(2x+55) = 180

4x+192 = 180

4x = 180-192

4x = -12

x = -12/4

x = -3

Use this x value to find the base angle

B = base angle

B = 2x+55

B = 2*(-3)+55

B = -6+55

B = 49 degrees

Answer:

  3 solutions: 1368, 5364, 9360

Step-by-step explanation:

In order to be divisible by 36, the number must be divisible by 9 and by 4. The number will be divisible by 9 if the sum of its digits is divisible by 9. 36 already has a digit sum of 9, so the two added digits must sum to 9.

The number will be divisible by 4 if the least-significant digit is a multiple of 4. That is, it must be 0, 4, or 8. Then the corresponding most-significant digits must be 9, 5, or 1.

The three solutions are ...

  1368 = 38 · 36

  5364 = 149 · 36

  9360 = 260 · 36

Answer:

C. [tex]6+z=44\Rightarrow z=38\ \text{inches}[/tex]

Step-by-step explanation:

The plant has initial length of [tex]6\ \text{inches}[/tex]

Let the height it grew after the [tex]6\ \text{inches}[/tex]  be [tex]z[/tex]

So total height it grows would be [tex]6+z[/tex]

The total height of the plant is [tex]44\ \text{inches}[/tex]

So we get

[tex]6+z=44\\\Rightarrow z=44-6\\\Rightarrow z=38\ \text{inches}[/tex]

The equation that models the situation is

Answer:

y = 5x + 11

Step-by-step explanation:

- first rearrange -5x + y = 2 and you'll have y = 5x + 2

- the slopes of parallel lines are equal so the slope of the line is 5

so far we have y = 5x + b

- to get b, replace the values in the equation by the values of the given point

(1) = 5(-2) + b

- rearrange and calculate, b = 11

y = 5x + 11

Answer:

y - 5 = -4(x + 1)

Step-by-step explanation:

The point-slope form is y - k = m(x - h).  The point is (h, k):  (-1, 5) and the slope is -4.

Here we have y - 5 = -4(x + 1)

The required point-slope form of the equation of the line is y - 5 = -4(x + 1).

Given that, To determine an equation in point-slope form for the line that passes through the point with the given slope. point: (-1, 5) and m=-4.

The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.

Here,
The point-slope of the equation of the line is given by,
y - y₁ = m(x - x₁)
Put the values in the above equation of the line
y - 5 = -4 (x - (-1))
y - 5 = -4 (x + 1)

Thus, the required point-slope form of the equation of the line is y - 5 = -4(x + 1).

Since 3 roots are rational but one of the four is irrational. Then, there must be a conjugate pair for that which we can do by reversing the sign between the rational and the non-rational part.

Answer:

75

Step-by-step explanation:

In this problem, AC and BD should be set equal to each other.

3x + 15 = 4x - 5

You would then solve for x, which is x = 20.

Plug 20 back in the equation for AC, 3(20) + 15, to get 75.  

The length of AC is 75.

A rectangle is a two-dimensional shape where the length and width are different.

The area of a rectangle is given as:

Area = Length x width

We have,

AC = 3x + 15

BD = 4x - 5

AC and BD are diagonals of the rectangle.

The diagonals of a rectangle are equal.

Now,

AC = BD

3x + 15 = 4x - 5

15 + 5 = 4x - 3x

20 = x

Now,

AC = 3x + 15

= 3 x 20 + 15

= 60 + 15

= 75

Thus,

AC = 75
