Answer:
S = 23.6
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin S = opp / hyp
sin S = 4/10
sin S = 2/5
Taking the inverse sin of each side
sin^-1 ( sin S) = sin ^-1 (2/5)
S=23.57817
Rounding to the nearest tenth
S = 23.6
We know that a class interval must be greater than what the I formula solution is; however... What is the solution for class interval (for the formula) for a frequency distribution if the data ranges from 100 to 220 with 50 observations?
Answers
Answer:
Therefore the answer is 20.
Step-by-step explanation:
We know that
class interval = range / number of classes
But here number of classes is not given , so we use the formula
class interval = range / ( 1+ 3.322 log N)
where , range =maximum - minimum = 220-100 = 120
N= number of observations = 50
class interval = 120 / ( 1+ 3.322 * log 50) = 18.06
Rounding up to a convinient number
Thus , class intervai = 20
Therefore the answer is 20.
While hovering near the top of Ribbon Falls in Yosemite National park at 1600 feet, a helicopter pilot accidentally drops his sunglasses. The height h(t) of the sunglasses after t second is given by the polynomial function h(t)=-16t^2+1600. When will the sunglasses hit the ground? (Hint: Let the height,h(t), be 0 and solve for t.)
Answers
Answer:
10 seconds
Step-by-step explanation:
Plug in 0 as h(t) and solve for t:
h(t) = -16t² + 1600
0 = -16t² + 1600
-1600 = -16t²
100 = t²
10 = t
So, the sunglasses will hit the ground after 10 seconds

Answers

Answer:
-36
Step-by-step explanation:
Using the expression for the general term, you can fill in the known values and solve for the parameters of the sequence.
an = a1 +d(n -1)
a8 = a1 + d(8 -1) = 60
a12 = a1 + d(12 -1) = 48
The difference of these equations is ...
(a1 +7d) -(a1 +11d) = (60) -(48)
-4d = 12
d = -3
Substituting into the first equation, we have ...
a1 +7(-3) = 60
a1 = 81 . . . . . . . . . add 21
Then the 40th term is ...
a40 = 81 -3(40 -1) = 81 -117
a40 = -36
Identify the first 4 terms in the arithmetic sequence given by the explicit formula ƒ(n) = 8 + 3(n – 1).
A) 8, 11, 14, 17
B) 3, 11, 19, 27
C) 8, 5, 2, –1
D) 3, –5, –13, –21
Answers
Answer:
A
Step-by-step explanation:
an arithmetic sequence adds a constant from every previous term to create the next term.
it starts with a first term, a1, meaning that n >=1
a1 = 8 + 3×(1-1) = 8 + 3×0 = 8
so, B and D are out.
the next term is a2.
a2 = 8 + 3×(2-1) = 8 + 3×1 = 11
and so, only A can be correct.
just to verify
a3 = 8 + 3×(3-1) = 14
a4 = 8 + 3×(4-1) = 17
and it also fits overall,
starting with 8, every new term is the previous term + 3.

Answer:
See below.
Step-by-step explanation:
7.)
Supplementary angles add up to 180°. ∠B's supplement is 22°. This means ∠B is 158°. Since ∠A ≅ ∠B, the m∠A = 158°.
8.)
Again, supplementary angles add up to 180°. ∠P is a right angle meaning it is 90°. Therefore, the m∠Q is 90° as well.
9.)
Complementary angles add up to 90°. In order for ∠S and ∠T to be complementary, they both need to angle measurements less than 90° meaning they both need to be acute angles.
Now that we know that ∠T is acute, the only way ∠U can be its supplement is if it has an angle measure greater than 90°. Therefore, ∠U is an obtuse angle.
10.)
Similar to question 9, if an angle is obtuse, its supplement must be an acute angle.

Answers
Answer:
[tex]y=-2x+6[/tex]
Step-by-step explanation:
Slope-intercept form is given as [tex]y=mx+b[/tex], where [tex]m[/tex] is slope and [tex]b[/tex] is the y-intercept.
To find the slope of a line that passes through two points [tex](x_1, x_2)[/tex] and [tex](y_1, y_2)[/tex], use the slope formula:
[tex]m=\frac{\Delta y}{\Delta x}=\frac{y_2-y_1}{x_2-x_1}[/tex]
Let:
[tex](x_1, y_1)\implies (1, 4)\\(x_2, y_2)\implies (0, 6)[/tex]
The slope of the line that passes through these two points is:
[tex]m=\frac{6-4}{0-1}=\frac{2}{-1}=-2[/tex]
Now substitute [tex]m=-2[/tex] and any point to solve for [tex]b[/tex]:
[tex]y=mx+b,\\6=-2(0)+b,\\6=0+b,\\b=6[/tex]
Therefore, the slope-intercept form of a line that is represented by the table is [tex]\boxed{y=-2x+6}[/tex]

Find the ratio of A : B: C when
(a) A : B = 3 : 5 A : C = 6 : 7
Answers
9514 1404 393
Answer:
A : B : C = 6 : 10 : 7
Step-by-step explanation:
The A value is common to both ratios. In order to form the ratio A:B:C we must have the number of ratio units representing A be the same in both A:B and A:C. That number must be the least common multiple of 3 and 6, which is 6.
Multiplying the first ratio by 2, we have ...
A : B = 6 : 10
A : C = 6 : 7
So, we can write the triple ratio as ...
A : B : C = 6 : 10 : 7

What is a ratio?The ratio is a comparison between two or more than two similar things in simplest form. There are two types of proportion in ratio one is direct proportion and another is inverse proportion. In direct proportion, all quantities increase or decrease simultaneously and in inverse proportion if one quantity increases another decrease.
We know we can write a : b as a/b and: : as an equal to sign.
The given statement says 14 : x is in proportion to 28 : 7.
∴ 14 : x : : 28 : 7.
14/x = 28/7.
