The probability that the Yankees would score fewer than 5 runs when they lose the game is 0.44.

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

The probability that the Yankees will win a game P(win) = 0.57

The probability that the Yankees will score 5 or more runs in a game is:

P(s>5) = 0.46

The probability that the Yankees lose and score fewer than 5 runs is:

P(s<5) = 0.33

To find the probability that the Yankees would score fewer than 5 runs when they win the game:

This is the case of probabilities of one event and another event together we will multiply the respective probabilities of the event:

= 0.57 + 0.33 - 0.46

= 0.44

Thus, the probability that the Yankees would score fewer than 5 runs when they lose the game is 0.44.

Using conditional probability, it is found that the correct option regarding whether the events are independent is given by:

A. No, they are not independent because P(student) = 0.80 and P(student|Viking) =0.94.

Conditional probability is the probability of one event happening, considering a previous event. The formula is:

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which:

An event B is classified as independent if:

P(B|A) = P(B).

In this problem, 100 out of the 125 people sampled are students, hence the probability is given by:

P(student) = 100/125 = 0.8.

Out of the people that prefer to be a Viking, 80 out of 85 people are students, hence:

P(student|Viking) = 80/85= 0.94.

The probabilities are different, hence the events are not independent, and option A is correct.

The walker has travelled 9km, so

11.25km - 9km = 2.25km left

Step-by-step explanation:

The inverse function is:

[tex]g(x) = 27*x^3 - 4[/tex]

And g(2) = 212.

We need to find g(x) such that:

g(h(x)) = x.

We know that:

[tex]h(x) = \frac{\sqrt[3]{x + 4} }{3}[/tex]

Then our function must be a cubic, multiplied by 3^3 = 27, and then subtracts 4, it is:

[tex]g(x) = 27*x^3 - 4[/tex]

As you can see, if you evaluate in h(x), the outcome is x.

Now we can evaluate this in x = 2, we get:

[tex]g(2) = 27*2^3 - 4 = 212[/tex]

The correct option is C.

I'm not sure how your calculator works, but I'm assuming you can copy/paste the given numbers into the calculator somehow to have it determine the regression equation.

The tool I used is GeoGebra and the regression equation it produced was

y = 1.2x - 21.3

Each decimal value is approximate and rounded to the nearest tenth.

---------------------------

Once we determine the regression line, plug the homework grade x = 45 to find the associated test grade (y). This is a predicted test grade.

y = 1.2x - 21.3

y = 1.2*45 - 21.3

y = 32.7

y = 33

If a student got a 45 on a homework, then we predict their test grade should be around 33.

Answer:

Looking at the given points we know that it is going to be a triangle because it only have 3 points.  Therefore the figure is a triangle and the area formula would be [tex]A=\frac{1}{2}*b*h[/tex].

You can look at the attached graph and what we see is that our height of the triangle is from [tex]y=-3[/tex] to [tex]y=4[/tex] which means that our height is 7 units high.  We can also see that our base starts at [tex]x=-4[/tex] and ends at [tex]x=4[/tex] making us have a base of 8 units.

We then plug in the values and solve

[tex]A = \frac{1}{2}*7\ units * 8\ units[/tex]

[tex]A = \frac{1}{2}*56\ units^2[/tex]

[tex]A = 28\ units^2[/tex]

Therefore, the area of our triangle is [tex]28\ units^2[/tex]

Answer:

r ≈ 4

Step-by-step explanation:

circle = 360 degrees

360 / 90 = 4

let's call the area of triangle XYZ + the shaded area portion A

because ∠XYZ = 90°, and 360 / 90 = 4, A = 1/4th of the area

total area of circle = πr²

XY = YZ = radius

thus, as ∠XYZ = 90° and two sides are the same, this forms a 45-45-90 triangle, with base YZ and height XY (base/height are interchangeable here)

thus, area of triangle XYZ = r*r/2 = r²/2

area A = r²/2 + 4.64

4 * A = total area of circle

4(r²/2+4.64) = πr²

2r²+18.56 = πr²

subtract 2r² from both sides to put all the variables on one side

(π-2)r² = 18.56

divide both sides by (π-2) to isolate r²

18.56/(π-2) = r² ≈ 16.258

r ≈ 4.032 ≈ 4

If he answered 3 questions correctly, then the number of questions is got wrong is 7 and the number of questions that he did not attempt is 5.

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

In a class test of 15 questions, (+4) marks are given for every correct answer, (– 2) marks are given for every incorrect answer, and 0 marks are given for questions that are not attempted. Punit scored (– 2) marks.

If he answered 3 questions correctly, then the number of the question are got wrong and the number of the question that he did not attempt.

Let x be the correct question and y be the incorrect question, z be the number of questions that he did not attempt, and A be the number of the total score. Then we have

4x – 2z = A

x + y + z = 15

If A = -2 and x = 3, then we have

4 × 3 – 2z = -2

      12 + 2 = 2z

              z = 7

Then the value of y will be

3 + y + 7 = 15

           y = 5

Step-by-step explanation:

that is quite a lot of failing TVs.

if 5% are failing, this means you have a "chance" of 5/100 = 1/20 that your TV is among them.

that means the expected costs for replacement in the next 3 years are

1750 × 1/20 = 175/2 = $87.50

minus the $200 replacement plan the expected value is of course negative :

87.5 - 200 = -$112.50

and if your TV breaks after more than 3 years, the expected value is actually -1750 - 200 = -$1,950

which is the principle of replacement plans, and why I never buy one.

but sure, for the 5% with broken TVs this pays off big time (it is kind of a lottery).

Answer:

Hope this helps :)

7,614 is closer to 8,000 than it is to 7,000

This is because if the number has the hundreds place with 500 or more than it would be round up. If it's less than 500 than round down.

Also 7,614 rounded to the nearest thousand is 8,000 because the 6 in the hundreds place is more than 5 so we round up in the thousands place. The final answer would be 8,000.
