Answer:
Step-by-step explanation:
36n³ = 2 * 2 * 3 * 3 * n * n *n
6n² = 2*3 * n * n
GCF = 2 * 3 * n * n = 6n²
-36n³ = 6n² * (-6n)
-36n³ + 6n² = 6n²*(-6n) + 6n²
= 6n² ( -6n + 1)

Find the expected value and standard deviation.
Answer:
1) E(X) = 1.5
2)SD = 1.118
Step-by-step explanation:
1) Formula for expected value of this set of data is;
E(X) = Σx * P(x)
Σx = 0 + 1 + 2 + 3 = 6
And P(x) = ¼
Thus;
E(X) = 6 × ¼ = 1.5
2) Formula for the standard deviation is;
SD = √Σ((x - μ)²•P(x))
Where μ is the expected value = 1.5
At x = 0,we have;
(0 - 1.5)² × 1/4 = 0.5625
At x = 1, we have;
(1 - 1.5)² × 1/4 = 0.0625
At x = 2, we have;
(2 - 1.5)² × 1/4 = 0.0625
At x = 3, we have;
(3 - 1.5)² × 1/4 = 0.5625
Thus,Σ((x - μ)²•P(x)) = 0.5625 + 0.0625 + 0.0625 + 0.5625 = 1.25
Thus;
SD = √1.25
SD = 1.118

9514 1404 393
Answer:
31.243 units
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relationships between sides and angles in a right triangle. Using the attached figure, it is convenient to find the length of BE as an intermediate step in the solution.
Sin = Opposite/Hypotenuse
sin(30°) = BE/100
BE = 100·sin(30°)
Then ...
Tan = Opposite/Adjacent
tan(58°) = BE/x
x = BE/tan(58°) = 100·sin(30°)/tan(58°)
x ≈ 31.243 . . . . units
_____
Comment on the figure
The intermediate problem in creating the figure was to locate point D. That was accomplished by locating point C on a line at an angle of 58° CCW from the horizontal, using point B as a center. Then D is the intersection of BC with the x-axis. BE is drawn perpendicular to the x-axis.

select all the statements that are true about the equation y=-2/3x+5
Answer:
The slope of the line is negative. The y-intercept is 5. The slope of the line is -2/3.
Step-by-step explanation:
With 2 given points on the line that are whole numbers, you can find the slope of the line with the equation [tex]m=\frac{y2-x2}{y1-x1}[/tex]. The answer will tell you whether it's negative or positive. For example, [tex]m=\frac{-2-1}{4-0} =\frac{-3}{4}[/tex]. The slope is negative for the example. The y-intercept would be the point with 0 as the x-value: (0, -5).
0.6(2n-9) = 3.4-2 (3n-1)
solve the following equation only
Answer:
n=1.5
Step-by-step explanation:
distribute: 1.2n-5.4= 3.4-2(3n-1)
Add numbers]: 1.2 n - 5.4= 5.4-6n
Move terms: 1.2n+6n- 5.4=5.4
Add like terms: 7.2n= 5.4+5.4
Divide both sides of equation by 7.2
Answer n= 1.5
what is the equation of the line that goes througtthe points (4,-1) and (2,3)?
Answer:
y = -2x + 7
Step-by-step explanation:
Answer:
Step-by-step explanation:
recall the two formulas
y = mx - b slope-intercept
y - y1 = m(x-x1) point-slope
with these we can get the equation . we also need to find the slope m
m = y2-y1 / x2-x1
m = 3 - (-1) / 2-4
m = 3 + 1 / -2
m = 4 / -2
m = -2
now with the slope known, plug in either point into the point-slope formula and work to the slope-intercept formula, I'll use (2,3) as the point to plug in.
y - 3 = -2(x-2)
y - 3 = -2x +4
y = -2x + 7
there.. that's your answer
y = -2x + 7

She square was 10 ft by 10 ft. Suppose uses the same amount of fencing to enclose a circular area. What is the area of the circle? Use 3.14 for .
Answer:
127.41ft^2
Step-by-step explanation:
Given data
DImension of the square
10ft by 10ft
The perimeter of the square is
=10+10+10+10
=40ft
Hence the amount of the fencing of the circle is 40ft
That is the circumference is 40ft
C=2πr
solve for r
40=2*3.14*r
40=6.28r
r= 40/6.28
r=6.37 ft
Area= πr^2
Area= 3.14*6.37^2
Area= 3.14*40.5769
Area= 127.41ft^2

What is the height of a tree if a man standing 5 feet tall is 42 ft from the tree and sees the top of the tree at an angle of elevation of 32°?
Answer: [tex]31.24\ ft[/tex]

Given
The height of a man is 5 ft
Distance between man and tree is 42 ft
the angle of elevation is [tex]32^{\circ}[/tex]
Suppose h is the height of the tree
[tex]\Rightarrow \tan 32^{\circ}=\dfrac{h-5}{42}\\\\\Rightarrow h-5=26.24\\\Rightarrow h=31.24\ ft[/tex]

Isolate the x term by adding 21 on both sides:

Use the Triangle Inequality Property to determine whether a triangle can be formed with the given side lengths. 4 m, 8 m, 9 m *
Answer:
Therefore a triangle can be formed with side lengths of 4 m, 8 m, 9 m
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. There are different types of triangles such as scalene, isosceles, equilateral and so on.
The triangle inequality property states that the sum of any two sides of a triangle must be greater than the third side. If a, b and c are the sides of a triangle then:
a + b > c; a + c > b; b + c > a
Given a triangle with side length 4 m, 8 m, 9 m:
4m + 8m = 12m > 9m
4m + 9m = 13m > 8m
8m + 9m = 17m > 4m
Therefore a triangle can be formed with side lengths of 4 m, 8 m, 9 m.

Step-by-step explanation:
Hey There!
So they want us to find the sine of angle S
well remember is sohcahtoa
S - sine
O - opposite
H - hypotenuse
meaning that
[tex]Sin=\frac{opposite}{hypotenuse}[/tex]
The opposite side of angle S is 28 and the hypotenuse is 53
so [tex]sinS=\frac{28}{53}[/tex]
