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:

its not bounded

Step-by-step explanation:

if a sequence is bounded both above and bounded below then we say its bounded. we can only conclude that 3.115 is either upper bound or the lower bound.

Answer:

Step-by-step explanation:

Set each factor equal to zero and solve for the indicated variable.

x + 2 = 0 yields x = -2, or (-2, 0).  Plot this (-2, 0).  (This is the x-intercept.)

y - 5 = 0 yields y = 5, or (0, 5).  Plot this (0, 5)    (This is the y-intercept.)

Finally, draw a line through these two intercepts.

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

Answer:

120 girls attended the school play. :)

Step-by-step explanation:

there are 200 children.

40% are boys.

this means 60% are girls.

60% + 40% = 100%

60% of 200 is 120

Answer:

120 Girls attended the school play.

Step-by-step explanation:

We know that 40% of 100 is 40, so you double that and get 40% of 200 is 80.

Then you do 120-80=40.

The volume is 180 in

Step-by-step explanation:

Volume is the quantity of three-dimensional space enclosed by a closed surface, for example, the space that a substance (solid, liquid, gas, or plasma) or shape occupies or contains. Volume is often quantified numerically using the SI derived unit, the cubic metre. The volume of a container is generally understood to be the capacity of the container;

The average of the sample means is 14.98.

As the number of surveys conducted increases, the average of the sample means approaches the population mean.

Step-by-step explanation:

Plato

The average of the sample mean from the given data values in the table is gotten as; 14.98

When finding the average, we need to sum up all the given data and then divide by the total number of data.

The given data values are; 15.09, 14.45, 14.91, 15.09, 14.91, 15.82, 14.36, 15.55, 14.36, 15.27.

The sum of these given data is;

15.09 + 14.45 + 14.91 + 15.09 + 14.91 + 15.82 + 14.36 + 15.55 + 14.36 + 15.27 =  149.81

Thus;

Average of sample mean = 149.81/10

Average = 14.98

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

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!

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: 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:

  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.
