The probability best prediction for the number of times that Ellen will draw a blue marble is 200.

Number of blue marbles: 222

Number of red marbles: 333

Total number of marbles: 555

Probability of drawing a blue marble:

222/555

= 0.4

Number of times drawing a blue marble:

300300300 x 0.4

= 120,120,120

Rounded to nearest whole number:

120,120

Ellen has a bag with 333 red marbles and 222 blue marbles in it. She is going to randomly draw a marble from the bag 300300300 times, putting the marble back in the bag after each draw. The best prediction for the number of times that Ellen will draw a blue marble is 200. This prediction is based on the fact that there are more red marbles than blue marbles in the bag. To calculate this, we first need to determine the probability of drawing a blue marble; there are 222 blue marbles out of 555 total marbles, so the probability is

222/555

= 0.4.

Multiplying this by the total number of draws (300300300) gives us 120,120,120. Rounding this to the nearest whole number gives us our prediction of 200 times.

Answer:

The answer is "4.3".

Step-by-step explanation:

Given:

[tex]\to x^3 - 5x - 59 = 0[/tex]

When [tex]x = 4.1:[/tex]  

[tex]\to f(4.1) = (4.1)^3 - 5(4.1) - 59 = -10.579[/tex]

When [tex]x= 4.2:[/tex]

[tex]f(4.2) = 4.2^3 - 5(4.2) - 59 = -5.912[/tex]

When [tex]x = 4.3:[/tex]

[tex]\to f(4.3) = -0.993[/tex] (closer to 0)

[tex]\to f(4.4) = 4.184[/tex]

When [tex]x = 4.35:[/tex]

[tex]\to f(4.35) = 1.563[/tex]

When the root is closer to 4.3 than 4.4 So, 1.563 is closer to zero than 4.184.

When [tex]x = 4.32:[/tex]

[tex]\to f(4.32) = 0.0216[/tex] close to zero.

So the answer is 4.3 to 1 decimal place.

Proportion who would be traveling by car :

Number traveling By car / number of samples

p(car) = 23 / 75 = 0.30666

If total number of students = 1138

Jacks meeting lasted for 160 min or 2 hrs 40 min.

Time is the continued sequence of existence and events that occurs in an apparently irreversible succession from the past, through the present, into the future.

Given is that jacks meeting stared at 2:45 pm and ended at 5:25 pm.

The time for which the meeting lasted can be written as -

{i} = 2:45 pm

{i + 60 minutes} = 3:45 pm

{i + (2 x 60) minutes} = 4:45 pm

{i + (2 x 60 + 40) minutes} = 5:25 pm

{f} = 5 : 25 pm

The meeting lasted for -

2 x 60 + 40

160 minutes

or

2 hours 40 minutes

Therefore, Jacks meeting lasted for 160 min or 2 hrs 40 min.

The value of {a} in the given modelled statement equation is 5.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign "=".

Given is that the ages of three cats are (a) , (a + 4) and (2a - 3). Their total age is 21.

We can model the given equation is -

(a) + (a + 4) + (2a - 3) = 21

a + a + 4 + 2a - 3 = 21

4a + 1 = 21

4a = 20

a = 5

The number of units that tile will he need to surround his pool is 19.82units.

this question is of quadratic equation ,

The number of units of tile simply refers to the perimeter.

So, we need to find all the sides of the rectangle.

Now, we have,

AB = 4.24 units

BD = 7.07 units.

So, we can find AD using pythagoras theorem.

So,

(AD)² + 4.24² = 7.07²

(AD)² + 17.978 = 49.985

(AD)² = 49.985 - 17.978

AD = √32.007

AD = 5.66 units

AD = BC = 5.66 units

Likewise, AB = DC = 4.24 units

Thus,

perimeter = 2(5.66) + 2(4.24) = 19.8 units.

The number of units that tile will he need to surround his pool is 19.82units.

The area of ΔADC is equal to 6 unit².

The total area that is bounded by a triangle's three sides is referred to as the triangle's area. In essence, it is equal to 1/2 of the height times the base, or A = 1/2 b h.

A abc = A adc because the areas of the initial and reflected triangles are equal.

Using the formula area=1/2 base height, determine the area of triangle ABC.

ABC in a triangle:

base = 4 units + AC

height = 3 units + BE

AΔ= abc = 1/2×4×3 =6 unnit²

Answer: Let x be the number of piles of wood that Mr. Anderson made.

We know that he sold 25 pieces of wood to his neighbor, and the rest of the pieces of wood were divided into piles around his house, with each pile containing 40 pieces of wood.

Therefore, we can set up the equation:

185 pieces - 25 pieces = x * 40 pieces

Simplifying the equation:

160 = x * 40

To find the value of x, we need to divide 160 by 40

160/40 = x

x = 4

Therefore, Mr. Anderson made 4 piles of wood after he sold 25 pieces of wood to his neighbor.

It's worth noting that this equation was used to find the number of piles of wood Mr. Anderson made after selling 25 pieces to his neighbor, and assuming that he didn't use the rest of the wood for anything else except for making the piles.

The measure of the exterior angle of the triangle is 139°.

The exterior angle theorem states that the measure of an exterior angle is equal to the sum of the measures of the two remote interior angles of the triangle.

From the two given angles are 75° and 64° and exterior angle is 2.

Now, ∠2=75°+64°

∠2=139°

The limit of x approaching infinite of a function gives it's horizontal assymptote. We use this to solve the question, getting the following answer:

Because Limit of f (x) as x approaches plus-or-minus infinity = 16, the function has a horizontal asymptote at y = 16.

Horizontal asymptote:

An horizontal asymptote is the value of y given by:

[tex]y = \lim_{x \rightarrow \infty} f(x)[/tex]

In this question:

[tex]f(x) = \frac{16x^2 - 35}{x^2 - 5}[/tex]

The horizontal asymptote is:

[tex]y = \lim_{x \rightarrow \infty} f(x) = \lim_{x \rightarrow \infty} \frac{16x^2 - 35}{x^2 - 5}[/tex]

Considering it is a limit of x going to infinite, we just consider the terms with the highest exponents both in the numerator and in the denominator, so:

[tex]y = \lim_{x \rightarrow \infty} \frac{16x^2 - 35}{x^2 - 5} = \lim_{x \rightarrow \infty} \frac{16x^2}{x^2} = \lim_{x \rightarrow \infty} 16 = 16[/tex]

Thus, the correct answer is:

Because Limit of f (x) as x approaches plus-or-minus infinity = 16, the function has a horizontal asymptote at y = 16.

From the graph of the function, given at the end of this answer, you can check that as x goes to infinity, y(green line) approches 16(blue line).

Given the expression

x²+4x+7 = 0

a = 1, b = 4 and c = 7

Substitute

x = -4±√4²-4(1)(7)/2(1)

x  = -4±√16-28/2

x = -4±√-12/2

x = -4±√4*-3/2

x = -4±2√-3/2

x = -4±2√3i/2
