lee has a collection of dvds he had 8 dramas 15 comedies and 2 westerns if he selects at random a dvd to watch what is the probability that he will select a western

Answers

Answer 1
Answer:  2/25

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

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!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

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]

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

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.

Which function is represented by the table of values below?

Answers

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

Graph the line. y = -5x + 1

Answers

Answer:

See below.

Step-by-step explanation:

To graph y = -5x + 1 we must move 1 unit up and 5 units down plus a unit to the right

Since the slope is negative, therefore, we move down 5 units

Since the y-intercept is positive 1 then we move 1 unit up

Important Note: Start by the y-intercept first, then the slope

The slope of the line below is 2. Which of the following is the point-slope form

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)

(a) A : B = 3 : 5 A : C = 6 : 7

Answers

A: a:b=c answer is A:B=3:5

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

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

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.
