33 1/3% of what number is 12?
Answers
It’s actually something like 11.99... but close enough when rounded.
[tex]33\frac{1}{3}[/tex]% of 36 is 12.
What is percentage ?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.

What is the equation, in slope-intercept form, of the line parallel to -5x + y = 2 that passes through the point
with coordinates (-2, 1)?
Answers
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
Write an equation in point-slope form for the line that passes through the point with the given slope. point: (-1, 5) and m=-4
Answers
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).

Answers
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.

In rectangle ABCD, AC = 3x+15 and
BD
4x-5. Find the length of AC.
Answers
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.
What is a rectangle?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
