Explanation:
There are A = 2 westerns out of B = 8+15+2 = 25 movies total
The probability of selecting a western is A/B = 2/25
In decimal form, this is 2/25 = 0.08 which converts to 8%
Answer:
2/25
Step-by-step explanation:
so first u have to add them all up to get 25 because 8 +15+2=25. then, since there are 2 westerns, the probability that he will select a western is 2 out of 25

QUICK PLS HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
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
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

9514 1404 393
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
The slope of the line below is 2. Which of the following is the point-slope form
of the line?
Answer:
y+1 = 2(x-1)
Step-by-step explanation:
Point slope form for a line is
y-y1 = m(x-x1) where m is the slope and (x1,y1) is a point on the line
We are given the point(1,-1)
y --1 = 2(x-1)
y+1 = 2(x-1)

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

A. 525
B. 10
O c. 5
D. 515
Answer: 5

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.

Answer:
fog(x) is D = 6[tex]\sqrt{x}[/tex]
Step-by-step explanation:
I. square all value, so f(x) is 2x then g(x) is 18x
II. Replace x.value in f(x) with g(x).value = 2(18x)
III. If x is 1, 2(18*1) will be 36; find root, so answer is 6
If x is 2, 2(18*2) will be 72; find root, so answer is 6[tex]\sqrt{2}[/tex]

The center of dilation (point D) is a point that doesn't move. Any line not through that point will be moved to a parallel location when a dilation factor is applied.
Any line through the center of dilation will still go through the center of dilation. Its slope does not change, so the line will appear to be the same.

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
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.
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.)
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
Which function is represented by the table of values below?
Answer:
A. y = -x + 1
Step-by-step explanation:
The function can be represented in the slope-intercept form such as y = mx + b
m = slope = change in y/change in x
b = y-intercept = the starting value or the value of y when x is 0.
✔️Find slope (m) using two pair of values from the table, say (0, 1) and (1, 0):
Slope (m) = (0 - 1)/(1 - 0) = -1/1
Slope (m) = -1
✔️ y-intercept (b) = 1 (y = 1 when x is 0)
✔️Write the equation by substituting m = -1 and b = 1 into y = mx + b:
y = -1(x) + (1)
y = -x + 1
