Which is a measure of center of a distribution?
O A. mean
OB. range
O C. variance
OD. standard deviation
Solve for the measure of each angle. Trigonometry.
Answer:
∠A=26º
∠B=137º
∠C=17º
Step-by-step explanation:
We can use the Law of Cosines because we have all 3 side lengths.
cosA = [tex]b^2+c^2-a^2/2bc[/tex]
cosA=28^2+12^2-18^2 / 2(28)(12)
cosA=604/672
cos-1(604/672
angle A ≈ 26º
cosB = [tex]c^2+a^2-b^2/2ca[/tex]
cosB=-316/432
cos-1(-316/432
angle B ≈ 137º
26+137=163
180-163=17
angle C ≈ 17º

i need to factor 5n^2-16
Answer:
([tex]\sqrt{5}[/tex] n - 4)([tex]\sqrt{5}[/tex] n + 4)
Step-by-step explanation:
Using the factorising method, difference of 2 squares
a² - b² = (a - b)(a + b) , then
5n² - 16
= ([tex]\sqrt{5}[/tex] n )² - 4²
= ([tex]\sqrt{5}[/tex] n - 4)([tex]\sqrt{5}[/tex] n + 4)
Someone help and plz make sure it’s right
Answer:
9.4km
Step-by-step explanation:
6.2^2 +7.1^2 = x^2
so 38.44+ 50.41= 88.85
x^2= 88.85 so x = 9.4
Sorry if it's really confusing lol, if you need help i could explain it further but your answer is 9.4
a square was altered so that one side is increased by 9 inches and the other side is decreased by 2 inches. the area of the resulting rectangle is 60 square inches. What was the are f the original square.
Answer:
36 square inches.
Step-by-step explanation:
Since the original figure was a square, all four side lengths are equivalent. The area for the square will be:
[tex]A=s^2[/tex]
Where s is the length of one side.
One side is increased by nine inches and the other side was decreased by two inches. The area of the resulting rectangle is 60 square inches.
So, one of the new sides is (s + 9).
And the other is (s - 2).
The area with these dimensions is 60. Thus:
[tex]60=(s-2)(s+9)[/tex]
Solve for s. Distribute:
[tex]60=s^2+7s-18[/tex]
Isolate the variables:
[tex]s^2+7s-78=0[/tex]
Factor:
[tex](s+13)(s-6)=0[/tex]
Zero Product Property:
[tex]s+13=0\text{ or } s-6=0[/tex]
Solve for each case:
[tex]s=-13\text{ or } s=6[/tex]
A side length cannot be negative. So, our only solution is:
[tex]s=6\text{ inches}[/tex]
Since each side of the square measures six inches, the area of the original square will be 36 square inches.

Which algebraic expressions are like terms with 16K. Choose all that apply .
A 300 long wire is used to fence a rectangular plot whose length is twice its width find the length and breath
Answer:
Length = 100
Width = 50
Step-by-step explanation:
Given :
Length = 2 * width
If :
length = l
Width, w
l = 2w
Perimeter, P of rectangle :
P = 2(l + w)
P = 2(2w + w)
300 = 2(3w)
300 = 6w
w = 300/6
w = 50
l = 2w
l = 2(50)
l = 100

Quadrilateral ABCD is a rectangle. BE=2x+1 and AC=6x−12 . What is BE ?
Answer:
BE=15
Step-by-step explanation:
Since E is the center, BE=2x+1
And AC is 6x-12 with E being a midpoint.
Since AC is 2 segments and BE is only 1 then you multiply 2x+1 by 2 so that
you can find x. You multiply 2x+12 by 2 because E is the midpoint so that means ED is the same value as BE
6x-12=4x+2
BD=AC
6x-4x-12=2
2x=2+12
2x=14
x=7
BE= 2x+1
2(7)=14+1=15

use the law of Cosines so that you can solve a SSS triangle
Cos(C) = [tex]a^{2}[/tex] + [tex]b^{2}[/tex] - [tex]c^{2}[/tex] / 2ab
c is the side of 24 for our triangle and angle C is the top one in the picture.
C = arcCos ( [tex]a^{2}[/tex] + [tex]b^{2}[/tex] - [tex]c^{2}[/tex] / 2ab )
C = arcCos ( -32 / 480 )
C = 93.82255373 °
the angles at the top are each half of that or 46.91127 °
let's solve another angle for the big triangle now let's go for the one on the left and call it A
Cos(A) = [tex]c^{2}[/tex] + [tex]b^{2}[/tex] - [tex]a^{2}[/tex] / 2bc where a = 20
A = arcCos( [tex]c^{2}[/tex] + [tex]b^{2}[/tex] - [tex]a^{2}[/tex] / 2bc)
A = arcCos( [tex]24^{2}[/tex] + [tex]12^{2}[/tex] - [tex]20^{2}[/tex] / 2*12*24
A = arcCos(320 / 576)
A = 56.2510 °
then angle B is 180 =93.823 + 56.251 + B
29.926 ° = B
so now we know all 3 angles.. seems like a lot of work , huh :D
for the triangle with the question mark we now know two angles and the Hyp, so let's use Law of Sines to find that last side :)
Sin(A)/a = Sin(B) /b where A can be the angle at the top and B can be the angle at the base. which we have to find still :/
it's 180 = 46.9112 + 29.926 + B
103.162 = B
Sin(46.91127 ) / a = Sin(103.162) /20
Sin(46.91127 ) * 20 / Sin(103.162) = a
14.99998 = a I feel confident this is supposed to be 15 and I have a tiny bit of rounding error..
? = 15 there you go
your answer is 15

5(3x - 4) + 12 = 52
Write the steps you will use to solve the equation and explain each step.
Answer:
x = 4
Step-by-step explanation:
The steps we need to take:
1. Simplify left side.
2. Separate the variable and its coefficient from constants
3. Divide both sides by the coefficient to find "x
1) Simplify left side.
5(3x - 4) + 12 = 52
15x - 20 + 12 = 52
15x - 8 = 52
2) Separate the variable and its coefficient from constants by adding 8 to both sides.
15x - 8 + 8 = 52 + 8
15x = 60
3) Divide both sides by the coefficient to find x. (the coefficient is the number that comes before the variable)
15x / 15 = 60 / 15
x = 4
