My question is in the picture. Will give brainliest.

Answer:

66%

Step-by-step explanation:

The experimental probability of winning 5 or more tickets is 90%

To do this, we simply add the probability values of the bars that have a value of 5 or more

So, we have:

P(x >= 5) = (5 + 8 +17 + 19 + 20 + 21)%

Evaluate the sum

P(x >= 5) = 90%

Hence, the experimental probability of winning 5 or more tickets is 90%

Answer: well i have put things like leather and it shrunk while it was out in the sun

Step-by-step explanation:

We want to study how the Sun affects things on Earth, I will give you two examples.

First, we know that the Sun radiates electromagnetic energy.

So if you left something in the Sun, its temperature will increase (as it receives the radiation) but more things can happen.

The first example can be a plant, that if it was inside at first, and then you put it in the sun for a while, you will for sure see a change in the plant contexture. This happens because the Sun gives energy to the plant (or the plant utilizes the radiation that comes from the Sun as energy).

Another example (and another phenomenon) can be a black shirt that is left in the Sun for several hours. The radiation (UV radiation particularly) affects the dye in the shirt by a process called photodegradation. Thus, the color of the shirt fades away.

So these are just two different examples of how the Sun affects things on Earth.

Answer:

Rui will reach his lowest altitude after 20seconds of diving

Step-by-step explanation:

Given the function that models the altitude of Rui at any time x expressed as:

d(x) = 1/2 x² - 10x

The height of rui at his lowest altitude will be zero. Substitute d(x) = 0 into the expression and get x

d(x) = 1/2 x² - 10x

0 = 1/2 x² - 10x

-1/2x² = 10x

1/2 x = 10

Multiply both sides by 2

x/2 × 2 = 10×2

x×1 =20

x = 20

Hence Rui will reach his lowest altitude after 20seconds of diving

49 total dogs.

36 more small dogs.

13 big dogs.

lol just realized today's school has sh*t wording and this question can be taken TWO ways. 36 more as in, 36 more dogs in total or 36 more small dogs than large dogs adding the amount of large dogs with this. this gives us 49.

the only way to get the x value (large dogs) and add this on top of the 36 (small dogs) and get 49 is to do 6.5 + 42.5 (36 + 6.5) this gives us 49.

Thanks guy in the comments for giving the second response, after some thinking i realized that i could also read it that way.

F** k today's hw and their wording

Answer:

6.5 Large Dogs

42.5 Small Dogs

Step-by-step explanation:

You simply do not have enough love for dogs to solve the question.

Luckily I have an extremely high affection for dogs so I can help.

S = amount of small dogs

L = amount of large dogs

S + L = 49

S = 36 + L

plug the second equation into the correct variable of the first equation so:

(36+L) + L = 49

36 +2L = 49

2L = 49-36

L = 6.5      *this doesn't make sense*

S = 42.5    *this also doesn't make sense*

I don't know why your questions produce answers with 6 and a half dogs, haha, but these are the correct answers. Math never lies!

Answer:

C)

Step-by-step explanation:

Note that one of the lines is simply y=-1 for any x, so we can dismiss the only answer without y=-1. That rejected answer is A)

Now let's notice, that the other line is decreasing y when increasing x. That tells us that in the equation y = ax + b, a has to be negative. This brings us to reject option D).

What is the y of that line for x = 0? Because y = ax + b, for x = 0 we will get the value of b. This is called the intercept. The line is at y=4 for x=0, so we know that the b in the equation must be positive 4. This fits answer C, but rejects answer B). And so, we have found that C) is the only possible answer.

Answer:

  log₃(81) = 4

Step-by-step explanation:

There are a few ways you can go at this. Perhaps the simplest is to recognize that 81 is a power of 3.

  log₃(81) = log₃(3⁴)

  log₃(81) = 4

__

You can also use the "change of base" formula:

  log₃(81) = log(81)/log(3) ≈ 1.908485/0.4771213

  log₃(81) = 4

A suitable calculator works, too.

Answer: y = -2x + 6

Slope-intercept form: y = mx + b, where m = slope and b = y-int

m = -2

(-1, 8) --> -1 = x₁, 8 = y₁

Based on the slope and given point, use oint-slope form, y - y₁ = m(x - x₁), to find the slope-intercept equation:

y - 8 = -2[x -(-1)]

y - 8 = -2(x + 1)

y - 8 = -2x - 2

y = -2x + 6

Answer:

2340

Step-by-step explanation:

360/24 =15whichis number of sides

180(15-2)=2340

Answer:

Exterior Angle of 24º means Interior Angle of 156º

Interior Angle = 180 -Exterior Angle

Number of sides = 360 / (180 - ONE Interior Angle)

Number of sides = 360 / (180 - 156º)

Number of sides = 360 / 24

Number of Sides = 15

Answer: -4

Step-by-step explanation:

The common ratio of the geometric sequence  [tex]19, -76, \ 304, \ ...[/tex] is [tex](-4)[/tex] .

Geometric sequence also known as a geometric progression, is a sequence of non-zero numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio. i.e.  [tex]r=\frac{a_{k+1} }{a_{k} }[/tex]

Common ratio the number which is multiplied (or divided) at every stage of a geometric sequence.

We have,

Geometric sequence  [tex]19, -76, \ 304, \ ...[/tex]

Here,

[tex]a_{1} =19, \ a_{2} =(-76), \ a_{3} =304[/tex]

So,

[tex]r=\frac{-76}{19}[/tex]

[tex]r=(-4)[/tex]

So,

Common ratio of the given geometric sequence  is [tex](-4)[/tex] .

Hence, we can say that the common ratio of the geometric sequence  [tex]19, -76, \ 304, \ ...[/tex] is [tex](-4)[/tex] .
