If Sandy used a virtual coin toss app to show the results of flipping a coin 100 times, 500 times, and 1,000 times. The things that most likely happened in Sandy's experiment is: C. Sandy's experimental probability was closest to the theoretical probability in the experiment with 1,000 flips.

Sandy's experimental probability was closest to the theoretical probability in the experiment with 1,000 flips.

This is because as the number of trials increases, the experimental probability tends to as well  approach the theoretical probability. The theoretical probability of getting heads or tails in a fair coin flip is always 0.5 or 50%. The larger the sample size, the more likely the experimental probability will be close to the theoretical probability.

Therefore the correct option is C.

The real roots of the polynomial function are (a) r = -6 and r = 2

From the question, we have the following polynomial function that can be used in our computation:

s(r) = r^5 + 4r^4 - 13r^3 - 10r^2 - 12r + 72

At the real roots of the polynomial function, the following must be true

s(r) = 0

Using the above as a guide, we have the following:

Next, we test the options

Option (a)

s(-6) = (-6)^5 + 4(-6)^4 - 13(-6)^3 - 10(-6)^2 - 12(-6) + 72 = 0

s(2) = (2)^5 + 4(2)^4 - 13(2)^3 - 10(2)^2 - 12(2) + 72 = 0

See that s(-6) and s(2) have the values of 0

The total cost of a meal costing $32 with 7% sales tax and 18% automatic tip is $40

An equation is an expression that uses mathematical operations to show the relationship between numbers and variables. Types of equations are linear, quadratic, cubic and so on.

The sales tax is 7% and the automatic tip is 18%. If the meal costs $32, hence:

Sales tax = 7% of $32 = 0.07 * 32 = $2.24

Automatic tip = 18% of $32 = 0.18 * 32 = $5.76

The total cost = cost of meal + sales tax + automatic tip

Substituting:

Total cost = $32 + $2.24 + $5.76 = $40

The total cost is $40

The complete question is given below.

The approximation for the population of the bacteria 5 minutes from now is 3506 organisms.

Let's call the current time "t", and the population of the bacteria at time "t" be "P(t)".

So, we have two points on the curve:

(t, P(t)) = (0, 1661), and (t + 9, P(t + 9)) = (9, 3 * 1661) = (9, 4983).

The equation of the line that passes through these two points can be found using the point-slope form of the line:

y - y1 = m(x - x1)

Substituting the points into the equation, we get:

4983 - 1661 = m(9 - 0)

m = (4983 - 1661) / (9 - 0) = 3322 / 9 = 369

So, we have

y = 369x + 1661

For the next 5 minutes, we have

P(t + 5) ≈ y = 369 * 5 + 1661 = 3506 (rounded to the nearest whole number)

We can see a right triangle here, where the leash is the hypotenuse of that triangle.

Using the Pythagorean's theorem we can write:

leash = √( (10ft)² + (7ft)²)

leash = 12,2 ft

The exact value of sinθ = 15.5/23

And, The exact value of cosθ = 17/23

The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.

We have to given that;

The terminal side of angle θ intersects the unit circle in the first quadrant at x=17/23.

We know that;

The given parameters are represented as;

⇒ (x, y) = ( cos θ , sin θ )

Here, x = 17/23

Hence, We get;

⇒ cos θ = 17/23

Now, Using the following trigonometry identity;

⇒ cos²θ + sin²θ = 1

⇒ (17/23)² + sin²θ = 1

⇒ 289/529 + sin²θ = 1

⇒ sin²θ = 1 - 289/529

⇒ sin²θ = 529 - 289 / 529

⇒ sin²θ = 240/529

⇒ sin θ = √240/529

⇒ sinθ = 15.5 / 23

Thus, The exact value of sinθ = 15.5/23

This simplified form of given expression is: 21952s¹⁵t³/(-8s⁶t¹²) = 21952 / -8 *s¹⁵t³ / s⁶t¹² = 2744 / -1 * s⁹t⁻⁹

An expression or mathematical expression is a finite collection of symbols that is well-formed according to context-dependent norms. In mathematics, an expression is a phrase that has at least two numbers or variables and at least one arithmetic operation. Addition, subtraction, multiplication, or division are all examples of math operations. An expression in mathematics is a collection of numbers, variables, and functions (such as addition, subtraction, multiplication or division etc.) Expressions and phrases are similar in structure.

Now, we can multiply this result by the original expression raised to the power of 3:

(4s⁵t⁻⁷/−2s⁻²t⁴)³ * (1/(-8s⁶t¹²)) = (4s⁵t⁻⁷)³ / (-8s⁶t¹²)

The length of AB is 10 cm.

What is the Pythagorean Theorem?

The Pythagorean theorem is a mathematical theorem that states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. It can be expressed as c² = a² + b².

The length of AB can be found using the Pythagorean theorem. The theorem states that in a right triangle, the sum of the squares of the lengths of the two shorter sides equals the square of the length of the hypotenuse (the longest side). In this case, we can form two right triangles, one with sides AD and AC and another with sides BC and AB.

Using the Pythagorean theorem, we have:

AB² = AC² + AD²

AB² = (8²) + (6²)

AB² = 64 + 36

AB² = 100

AB = √(100) = 10

We have, 6% × x = 24 or, 6 100 × x = 24

Step-by-step explanation:

Multiplying both sides by 100 and dividing both sides by 6,

Answer:

24 % of that number is 4

Step-by-step explanation:

First solution:

If 6% of a number is 1, then 1% is 1/6 which is a repeating decimal, so we can just take it as 1/6. Then, to find 24% of that number we would have to do 1/6 x 24 which is equal to 24/6. 6 can evenly divide 24 which is 4.

Second solution:

We can see that since 24 is evenly divided by 6, to find 24%, we can multiply 1 by 4 because 6% x 4 = 24%

Therefore, 24% of that number is 4.

Let's let w = the width of the rectangle.  If the length is 10 yards less than 3 times the width, then the length is 3w - 10.

How do we find the area?  Length times width, right?

So, we have w(3w - 10) = 77.  Distributing, we get 3w2 - 10w = 77.

We need to put it all on one side, so we subtract 77 from both sides.

3w2 - 10w - 77 = 0

Now, we have to factor the left side. To do this, we multiply 3(-77) = -231.  What are two factors of -231 that add up to -10? How about -21 and 11?  -21(11) = -231 and -21 + 11 = -10.

This may not be how you are taught, but we are now going to split -10w into -21w + 11w and plug that into our equation.

Sooooo, now we have 3w2 - 21w + 11w - 77 = 0

Next, we are going to look at the first two terms, 3w2 - 21w.  What is common between the two? 3w. Factoring out 3w, we get 3w(w - 7).

Now, the second two terms, 11w - 77. What is common? 11. Factoring out 11, we get 11(w - 7).

Putting all of that together, we now have 3w(w - 7) + 11(w - 7) = 0.

I can explain why and make it more confusing, so I'll just tell you that, since the w - 7 is the same in both parentheses, we keep that as one set of parentheses and combine what's in front into a second set of parentheses.

So, we have (w - 7)(3w + 11) = 0

Lastly, for the left side to equal 0, then either w - 7 and/or 3w + 11 has to equal 0, right?

We pull each out and set them equal to 0.

w - 7 = 0

     w = 7

If we plug in 7, we get (7-7)(3(7) + 11) = (0)(21+11) = 0(32) = 0, which is what we want.

3w + 11 = 0

        3w = -11

          w = -11/3

If we plug -11/3 into the same equation, we'd get 0, again what we want.  However, we can't have a negative length!  Therefore, -11/3 is out as an answer.

Our width is 7.  Since the length is 3w - 10, we plug in 7 and get 3(7) - 10 = 21 - 10 = 11.

Let's check. Length times width = 7(11) = 77. Check!
