Answer: To write 6^-5 in expanded form, we need to first recall the definition of negative exponents. If a number a is raised to a negative exponent, it means that we take the reciprocal of a raised to the absolute value of the exponent. In other words:

a^(-n) = 1 / a^n

Using this definition, we can write:

6^-5 = 1 / 6^5

Now, we can expand 6^5 using repeated multiplication or by using a calculator. 6^5 means 6 multiplied by itself five times:

6^5 = 6 × 6 × 6 × 6 × 6 = 7776

Therefore, we can write:

6^-5 = 1 / 6^5 = 1 / 7776

So, the expanded form of 6^-5 is 1/7776.

Step-by-step explanation:

Apples make up one-third of the dozen fruits in a fruit vendor cart. If bananas make up the remaining fruit and oranges make up 1/4 of the total fruit, there are 2.5 dozen bananas in the fruit vendor's cart.

First, let's calculate how many apples are in the cart:

1/3 of 6 dozen fruits = 2 dozen fruits are apples

Next, let's calculate what proportion of the fruits are oranges:

1/4 of all fruits = (1/4) x 6 dozen = 1.5 dozen fruits are oranges

To find the number of dozen bananas, we can subtract the number of dozen apples and oranges from the total number of dozen fruits in the cart:

Total number of dozen fruits = 6 dozen

Number of dozen apples = 2 dozen

Number of dozen oranges = 1.5 dozen

Number of dozen bananas = 6 dozen - 2 dozen - 1.5 dozen

Number of dozen bananas = 2.5 dozen

Therefore, there are 2.5 dozen bananas in the fruit seller's cart.

The complete question is:-

1/3 of the 6 dozen fruits in a fruit seller cart are apple. If 1/4 of all the fruits are oranges and the rest of the fruits are bananas, find how many dozen bananas are there in the fruits sellers cart

The theoretical probability is 0.5 and the experimental probability is 0.583

Part A:

Since the coin is fair, the probability of it landing on heads is 0.5 or 50%.

The theoretical probability of a fair coin landing on heads is 0.5.

Part B:

Let's denote the outcome of flipping the coin as H (heads) or T (tails). We flip the coin 12 times and record the frequency of each outcome:

NB: This is an assumption and not a given data;

Outcome Frequency

    H              7

    T                      5

The experimental probability of landing on heads is calculated by dividing the number of times the coin landed on heads by the total number of coin flips:

Experimental probability of landing on heads = number of heads / total number of flips

Experimental probability of landing on heads = 7 / 12 = 0.583

Part C:

Comparing the experimental probability to the theoretical probability, we can see that they are different. The theoretical probability is 0.5, while the experimental probability is 0.583. This difference can be attributed to the randomness of the coin flips and the fact that we only flipped the coin 12 times, which is a relatively small sample size. As we increase the number of coin flips, the experimental probability should converge to the theoretical probability.

Answer:

£2947

Step-by-step explanation:

the formula for simple interest is interest = prt.

p is the principal value, or what omar had at the beginning.

r is the rate at that you gain interest.

t is the amount of time in years.

so, plugging in our values, we multiply 2800*3*0.0175 to get 147.

now, since that was the amount of interest omar gained, we still have to add the original amount that he had, and 2800+147 = 2947.

so, the answer is £2947.

The odds of answering at least 9 questions correctly out of 15 by choosing at random is approximately 0.120

To solve this problem, we can use the binomial distribution, which models the probability of getting a certain number of successes in a fixed number of independent trials, each with the same probability of success.

In this case, we have 15 independent trials (the 15 questions) and the probability of success in each trial is 1/4 (the probability of guessing the correct answer among 4 choices). We want to find the probability of getting at least 9 successes.

Using a binomial distribution calculator, we can calculate this probability as

P(X ≥ 9) = 1 - P(X < 9) = 1 - binomcdf(15, 1/4, 8) ≈ 0.120

where binomcdf is the cumulative distribution function of the binomial distribution, which gives the probability of getting up to a certain number of successes (in this case, up to 8). The complement of this probability (1 minus the probability of getting up to 8 successes) gives the probability of getting at least 9 successes.

To find the perimeter of a rectangle, we need to add up the lengths of all its sides.

First, gather the coordinates:

R - (4, 5)

U - (8, -3)

F - (-6, 0)

O - (-2, -8)

Using the coordinates given, we can calculate the lengths of the sides of the rectangle using the distance formula:

d = √((x2 - x1)^2 + (y2 - y1)^2)

So, for the rectangle with vertices R, U, F, and O, we have:

Side RU: d = √((8 - 4)^2 + (-3 - 5)^2) = √(16 + 64) = √80

Side UF: d = √((-6 - 8)^2 + (0 - (-3))^2) = √(196 + 9) = √205

Side FO: d = √((-6 - (-2))^2 + (0 - (-8))^2) = √(16 + 64) = √80

Side OR: d = √((-2 - 4)^2 + (-8 - 5)^2) = √(36 + 169) = √205

Since opposite sides of a rectangle are congruent, we have RU = FO and UF = OR. Therefore, the perimeter of the rectangle is:

Perimeter = RU + UF + FO + OR

Perimeter = √80 + √205 + √80 + √205

Perimeter ≈ 38.57

Therefore, the perimeter of the rectangle is approximately 38.57 units.

In a game of chance, the probability of winning 50 is 40 percent and the probability of having to pay 50 is 60 percent. Therefore, the expected value of this game is -10. The correct answer is option A.

What is Law of sines ?

The Law of Sines is a trigonometric formula that relates the side lengths of a triangle to the sine of its angles. It states that in any triangle ABC:

a / sin(A) = b / sin(B) = c / sin(C)

where a, b, and c are the side lengths of the triangle, and A, B, and C are the opposite angles.

This formula can be used to solve for the unknown sides or angles of a triangle when given enough information about the other sides and angles. The Law of Sines is especially useful when dealing with triangles that are not right triangles, or when only a few side lengths and angles are known.

According to the question:

We can solve this problem by using the Law of Sines and the fact that the sum of the angles in a triangle is 180 degrees.

First, we can find the measure of angle A in triangle ABC:

A = 180 - 48 - 48 = 84 degrees

Next, we can use the Law of Sines to find the length of side AC:

sin(84) / 50 = sin(48) / AC

AC = sin(84) * 50 / sin(48) ≈ 64.4

Now, we can use the fact that the sum of the angles in triangle AQS is 180 degrees to find the measure of angle QAS:

QAS = 180 - 20 - 90 = 70 degrees

Finally, we can use the Law of Sines again to find the length of RS:

sin(70) / RS = sin(48) / AC

RS = sin(70) * AC / sin(48) ≈ 72.6

Therefore, the length of RS is approximately 73 meters (to the nearest meter).

The length of line segment AC is equal to 34 units.

In Mathematics and Geometry, the Tangent Secant Theorem states that if a secant segment and a tangent segment are drawn to an external point outside a circle, then, the product of the length of the external segment and the secant segment's length would be equal to the square of the tangent segment's length.

By applying the Tangent Secant Theorem to this circle, we have the following:

DC² = AB × BC

15² = (3x + 1) × 9

225 = 27x + 9

27x = 225 - 9

27x = 216

x = 216/27

x = 8

Using Trigonometric functions, the height of the tree is approximately 50.6 feet.

Let's call the height of the tree "h" and the distance between the forester's original position and the base of the tree "x". Then, when the forester moves 20 feet closer to the tree, the distance between the new position and the base of the tree is "x - 20".

We can use the tangent function to set up two equations relating the height of the tree to the angles of elevation:

tan(37°) = h/x ...(1)

tan(52°) = h/(x - 20) ...(2)

We can solve this system of equations to find the value of "h". First, we can rearrange equation (1) to get:

x = h/tan(37°)

Then, we can substitute this expression for "x" into equation (2) and solve for "h":

tan(52°) = h/(h/tan(37°) - 20)

Simplifying and solving for "h", we get:

h = (20 tan(52°) tan(37°)) / (tan(52°) - tan(37°))

Using a calculator, we can evaluate this expression and find that:

h ≈ 50.6 ft

A derivative is a measure of how much a function changes as its input value changes. It is defined as the limit of the rate of change of the function with respect to its input as the change in the input approaches zero.

The function to represent the bacteria population after t hours, where the function's constant can be used to calculate the rate of change per minute is:

f(t) = 7400 * [tex]e^(0.13/60 * t)[/tex]

where:

f(t) = population of bacteria after t hours

e = Euler's number (approximately 2.71828)

t = time in hours

0.13/60 = rate of change per minute (converted from 13% per hour)

To determine the percentage rate of change per minute, we can calculate the derivative of the function with respect to time (t):

df/dt = 7400 * 0.13/60 * [tex]e^(0.13/60 * t)[/tex]

At t = 0 (the start of the experiment), the rate of change per minute is:

df/dt = 7400 * 0.13/60 * [tex]e^(0.13/60 * 0)[/tex] = 12.1166

To express this rate of change as a percentage, we can divide it by the initial population and multiply by 100:

rate of change per minute = (df/dt) / P(0) * 100% = 12.1166 / 7400 * 100% = 0.1638% (rounded to the nearest hundredth of a percent)

Pre-Solving:

We are given that [tex]\angle A[/tex] (which is equal to 22°) and [tex]\angle B[/tex] are vertical angles, and that [tex]\angle B[/tex] is complementary to [tex]\angle C[/tex].

We want to write an equation that will help us solve [tex]\angle C[/tex].

Solving:

Recall that vertical angles are congruent by vertical angles theorem.

This means that [tex]\angle A \cong \angle B[/tex]; it also means that the measure of [tex]\angle B[/tex] is also 22°.

Also recall that complementary angles add up to 90°.

This means that [tex]m\angle B + m\angle C = 90^\circ[/tex].

Since we deduced that [tex]m\angle B[/tex] is 22°, we can substitute that value into the equation.

Hence, an equation that can be used to solve for [tex]\angle C[/tex] is:

[tex]22^\circ + m\angle C = 90^\circ[/tex]

Answer:

m∠A = m∠B

m∠A = 22°

m∠B + m∠C = 90°

Step-by-step explanation:

∠A and ∠B are vertical angles. (Given)

By definition of vertical angles, a pair of angles with the same vertex and that are on opposite sides of two intersecting straight lines are congruent.

It is given that ∠A is 22°, and is a vertical angle with ∠B.

∴ ∠A ≅ ∠B (Definition of Vertical Angles).

IF m∠A = 22° and ∠A ≅ ∠B, THEN m∠B = 22° (Transitive Property of Equality).

∠B is complementary with ∠C (Given)

m∠B + m∠C = 90° (given).

m∠B = 22° (⇒Transitive Property of Equality)

Plug in 22 for m∠B in the given equation:

22 + m∠C = 90

Isolate the term, m∠C. Note the equal sign, what you do to one side, you do to the other. Subtract 22 from both sides of the equation:

m∠C + 22 (-22) = 90 (-22)

m∠C = 90 - 22

m∠C = 68°

Therefore, your system of equation will be:

m∠A = m∠B

m∠A = 22°

m∠B + m∠C = 90°
