Answer:

6 meters per 1 second or 6m/s

Step-by-step explanation:

slope is rise/run or change in y/change in x

in this case y=30, x=5 so slope = 30/5= 6

Answer:

a) 7/80 = 0.0875

b) 3/16 = 0.1875

c) 1/4 = 0.2500

Step-by-step explanation:

There are a total of 16 balls.  3 are selected.  There are ₁₆C₃ possible combinations.

a) If all 3 balls are the same color, they are either all yellow OR all blue OR all red.

The number of ways of choosing 3 yellow balls from 7 is ₇C₃.

The number of ways of choosing 3 blue balls from 5 is ₅C₃.

The number of ways of choosing 3 red balls from 4 is ₄C₃.

The total probability is:

P = (₇C₃ + ₅C₃ + ₄C₃) / ₁₆C₃

P = (35 + 10 + 4) / 560

P = 49 / 560

P = 7 / 80

P = 0.0875

b) The number of ways of choosing 2 yellow balls from 7 is ₇C₂.

The number of ways of choosing 1 blue ball from 5 is ₅C₁.

The probability of both is:

P = ₇C₂ ₅C₁ / ₁₆C₃

P = 21 × 5 / 560

P = 105 / 560

P = 3 / 16

P = 0.1875

c) If all 3 balls are different colors, then there is exactly 1 yellow, 1 blue, and 1 red.

The number of ways of choosing 1 yellow ball from 7 is ₇C₁.

The number of ways of choosing 1 blue ball from 5 is ₅C₁.

The number of ways of choosing 1 red ball from 4 is ₄C₁.

The probability of all events is:

P = ₇C₁ ₅C₁ ₄C₁ / ₁₆C₃

P = 7 × 5 × 4 / 560

P = 140 / 560

P = 1 / 4

P = 0.2500

Answer:

4 mm

Step-by-step explanation:

The radius is half the diameter, so in this case the radius of each button is 4 mm.

Answer:

The radius would be 4 millimetres

Step-by-step explanation:

The radius is the length from one side to the centre of the circle.

The diameter is the length from one side to another.

To work out the radius you would simply divide the diameter of 8 by 2, this gives you 4 millimetres. This is because the radius is half of the diameter.

1) Divide 8 by 2.

[tex]8/2=4 mm[/tex]

Answer:

4 meters

Step-by-step explanation:

Given a quadratic equation in which the coefficient of [tex]x^2[/tex] is negative, the parabola opens up and has a maximum point. This maximum point occurs at the line of symmetry.

Since the divers height, y is modeled by the equation

[tex]y= -x^2 + 2x + 3[/tex]

Step 1: Determine the equation of symmetry

In the equation above, a=-1, b=2, c=3

Equation of symmetry, [tex]x=-\dfrac{b}{2a}[/tex]

[tex]x=-\dfrac{2}{2*-1}\\x=1[/tex]

Step 2: Find the value of y at the point of symmetry

That is, we substitute x obtained above into the y and solve.

[tex]y(1)= -1^2 + 2(1) + 3=-1+2+3=4m[/tex]

The maximum height of the diver is therefore 4 meters.

Answer:

Factor [tex]12a + 6b : 6(2a + b)[/tex]

Step-by-step explanation:

[tex]12a+6b[/tex]

Rewrite [tex]12[/tex] as [tex]2 * 6[/tex]:

[tex]=2\cdot \:6a+6b[/tex]

Factor out common term [tex]6[/tex]:

[tex]=6\left(2a+b\right)[/tex]

The probability of reference book and then, without replacing it, picks up a nonfiction book is 5/136.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

Given:

Nadia's bookshelf contains 10 fiction books, two reference books, and five nonfiction books.

So, the probability of getting reference book

= 2/ 17

and, the probability of getting nonfiction book

= 5/ 17

Now, the probability of reference book and then, without replacing it, picks up a nonfiction book

= 2/ 17 x 5 / 16

= 10 / 272

= 5 /136

Answer:

108

Step-by-step explanation:

So the area of the rectangle is easy.

12 * 5 = 60

Now you have to do the triangles.

The height is (13 - 5) / 2 = 4

The bases are 12

The area of one is (12 * 4) / 2

The area of both is 12 * 4 = 48

60 + 48 = 108

Answer:

Step-by-step explanation:

Number of students 10

Problem 1. $625 for the bus hire per friday, So 625*4=$2500

Problem 2. 2500/25=$100 each for the whole 4 weeks

Problem 3.

10 students tickets 220= 2200 for all tickets. The bus, 625/10 = $62.5*4= $250 dollars for the whole 4 weeks for the bus so in all each student pays $470 each

20 students, tickets 220=4400 for all tickets. The bus, 625/20=$31.25*4=$125 for the whole 4 weeks for the bus, so in all each student must pay $345 each

30 students, tickets 220 = 6600 for all tickets. The bus, 625/30 =$20.83*4=$83.32 for the whole 4 weeks for the bus, so in all each student must pay $303.32 each

41 students, tickets $160=$6560 for all tickets. The bus, because you need 2 buses at 625 each so $1250 for both buses 1250/41= 30.49*4=$121.96 for the whole 4 weeks for the bus. So in al each student must pay $281.96 each

Hope this is correct

Answer:

x=7

Step-by-step explanation:

8x – 2y = 48

Let y = 4

8x - 2(4) = 48

8x - 8 = 48

Add 8 to each side

8x-8+8 = 48+8

8x = 56

Divide each side by 8

8x/8 = 56/8

x=7

Answer:

[tex]x = 7[/tex]

Step-by-step explanation:

[tex]8x - 2y = 48 \\ 8x = 48 + 2y \\ x = \frac{48 + 2y}{8} [/tex]

[tex]y = 4[/tex]

[tex]x = \frac{48 + 2y}{8} \\ x = \frac{48 + 2 \times 4}{8} \\ x = \frac{48 + 8}{8} \\ x = \frac{56}{8} \\ x = 7[/tex]

12=k6

12 divided by 6 to get 2

and 2=k

Answer:

f(x) = x^2 - 4x - 12

Step-by-step explanation:

If 6 is a zero, (x - 6) is a factor.  Likewise, if -2 is a zero, (x + 2) is a factor.

Multiplying these two factors together, we get:

f(x) = x^2 - 4x - 12

3(-3 + 7x) ≤ -93

-3 + 7x ≤ -31

7x ≤ -28

x ≤ -4

Answer: x ≤ -4

-6(1 + 8x) ≥ 138

Multiplying or dividing both sides by a negative number flips the sense of the inequality.

1 + 8x ≤ 138/(-6) = -23

8x ≤ -24

x ≤ -24/8

Answer: x ≤ -3

7(6x - 4) ≥ 6x - 28

42x - 28 ≥ 6x - 28

36x ≥ 0

x ≥ 0

Answer: x ≥ 0

Step-by-step explanation:

To create an histogram, we need to properly present the right solutions to angry mob.

The number of clubs per package is presented as thus

48 49 51 52 48 50 51 50 49 47 52 53 50 49 52 51 53 48 49 50

In an organized home, the data is reset to the number of clubs per passport and corresponding video is done

x | f

47 | 1

48 | 3

49 | 4

50 | 4

51 | 3

52 | 3

53 | 2

The histogram of this distribution is presented in the attached image to this answer.

-  The number of packages that contain between 48 and 52 clips (inclusive) per package

From the data table, it is evidently 3+4+4+3+3 = 17
