Calculate the ratio​

There are no orange M&Ms in the bag, thus there is no probability of picking one.

An event is any subset of the sample space, which is the set of all potential results of a random experiment, according to probability theory. By dividing the number of favourable outcomes by the total number of possible outcomes, the probability of an event is determined.

Classical probability, empirical probability, and subjective likelihood are just a few of the several varieties of probability. Empirical probability is based on actual observations or experiments, as opposed to classical probability, which is predicated on the idea that all events are equally likely. On the other hand, subjective probability is dependent on opinion or conviction.

Picking a yellow M&M has a 4/20 chance, which drops to 1/5.

The likelihood of selecting a blue or green card M&M is the result of adding the odds of selecting a blue and a green:

To reduce to 1/2, 2/20 + 8/20 = 10/20.

The likelihood of choosing an orange M&M is zero because there are no orange M&Ms in the bag.

The complete question is:

The appropriate domain for the function h(t) = −3t^2 + 9t + 12 is [0, 3.08].

The domain of a function is the set of all possible input values for which the function is defined. In this case, the function h(t) gives the height of the ball above the ground as a function of time t.

The ball is thrown from the tree house at some initial time, and it continues to travel until it hits the ground. The height of the ball is defined for all values of t between the time it is thrown and the time it hits the ground.

To find the domain of h(t), we need to determine the range of values of t for which the function is defined. The ball cannot have a negative height, so the function is undefined for values of t that would make h(t) negative.

To find the time at which the ball hits the ground, we need to set h(t) equal to zero and solve for t:

h(t) = -3t^2 + 9t + 12 = 0

Using the quadratic formula, we get:

t = (-9 ± √(9^2 - 4(-3)(12)))/(2(-3))

t = (-9 ± √(105))/(-6)

t ≈ -0.41 or t ≈ 3.08

Since the ball cannot have a negative height, the domain of the function is the interval [0, 3.08]. Therefore, the appropriate domain for the function h(t) = −3t^2 + 9t + 12 is [0, 3.08].

The perimeter of the new shape is 32 cm + 8 * sqrt(3) cm.

What is perimeter?

Perimeter is a measurement of the distance around a two-dimensional shape. It is the total length of the boundary or outer edge of the shape. In other words, it is the sum of the lengths of all the sides of the shape.

First, let's find the length of each side of the equilateral triangle, which was cut out of the square. Since the triangle was cut from a square, its sides have the same length as the sides of the square. Therefore, each side of the equilateral triangle is 8 cm.

Now, let's find the perimeter of the new shape, which is made by joining two of these shapes together. The new shape consists of two equilateral triangles and a rectangle. The length of the rectangle is the same as the side length of the equilateral triangle, which is 8 cm. The width of the rectangle is the same as the height of the equilateral triangle, which can be found by applying the Pythagorean theorem to one of the triangles:

[tex]height^2 = side^2 - (1/2 * side)^2\\\\height^2 = 8^2 - (1/2 * 8)^2\\\\height^2 = 64 - 16\\\\height^2 = 48\\\\height = \sqrt{(48)}\\\\height = 4 * \sqrt{(3)}[/tex]

Therefore, the width of the rectangle is also [tex]4 * \sqrt{(3)} cm.[/tex]

The perimeter of the new shape can be found by adding up the lengths of all four sides:

Perimeter = 2 * (side of equilateral triangle) + 2 * (length of rectangle + width of rectangle)

[tex]Perimeter = 2 * 8 cm + 2 * (8 cm + 4 * \sqrt{(3)} cm)\\\\Perimeter = 16 cm + 16 cm + 8 * \sqrt{(3)} cm\\\\Perimeter = 32 cm + 8 * \sqrt{(3)} cm[/tex]

Therefore, the perimeter of the new shape is [tex]32 cm + 8 * \sqrt{(3)} cm.[/tex]

Answer: b

Step-by-step explanation:

Answer:

We can use the Pythagorean theorem to solve this problem.

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides.

In this case, we know that the two sides have lengths of 2 cm and 6 cm, and we are trying to find the length of the third side, which we'll call x. We also know that the third side is not the hypotenuse, so we can't just assume that it's the longest side.

Using the Pythagorean theorem, we can write:

x^2 + 2^2 = 6^2

Simplifying, we get:

x^2 + 4 = 36

Subtracting 4 from both sides, we get:

x^2 = 32

Taking the square root of both sides, we get:

x = sqrt(32)

Simplifying, we get:

x = 4sqrt(2)

So the length of the third side is 4sqrt(2) centimeters.

The quadratic equation in standard form can be written as:

y = x² - 10

Remember that for a quadratic equation whose solutions are x₁ and x₂, the quadratic can be written as:

y = (x - x₁)*(x - x₂)

Here the solutions are:

x = √10

x = -√10

Then we can write:

y = (x+  √10)*(x - √10)

Let's use "p" for the quantity of pepperoni pizzas and "s" for the quantity of sausage pizzas. Finding p and s values that meet the requirements is necessary.

In light of the information provided:

One pepperoni pizza costs $8.

One sausage pizza costs $6.

100 pizzas are required.

Budget total: $740

To reflect the stated conditions, we can construct the following system of equations:

=> p + s = 100 (1)

=> 8p + 6s = 740 (2)

=> 8p + 8s = 800 (3)

=> 8p + 6s - (8p + 8s) = 740 - 800

=> -2s = -60

=> s = (-60)/(-2)

=> s = 30

=> p + 30 = 100

=> p = 100 - 30

=> p = 70

The correct answer is an option (A) 144.5 pounds per year, which is the closest value to the calculated average yearly growth rate of the elephant.

The term "average" refers to a measure of central tendency that represents the typical or typical value in a set of data.

Growth rate refers to the rate at which a quantity or value increases or decreases over time. It is often expressed as a percentage or a proportion and is used to measure the change in a particular variable relative to its initial value.

According to the given information:

To find the average yearly growth rate of the elephant, we can use the formula for calculating growth rate:

Growth Rate = ((Ending Value - Starting Value) / Number of Years)

In this case, the starting weight of the elephant is 220 pounds and the ending weight is 870.25 pounds. The number of years is 4.5 (since the growth occurred over 4.5 years).

Plugging these values into the formula, we get:

Growth Rate = ((870.25 - 220) / 4.5)

Simplifying the numerator, we get:

Growth Rate = 650.25 / 4.5

Dividing, we get:

Growth Rate ≈ 144.50 pounds per year

Answer:

Okay, let's think through this step-by-step:

• Janelle Monae obtained a $3,500 loan at 8.5% interest for 1 year.

• 8.5% interest for 1 year = 8.5% of $3,500 = $297.50 in interest

• The loan amount ($3,500) plus interest ($297.50) = $3,797.50 total paid back

•Monthly payments = $3,797.50 / 12 months = $285.55

• So the interest amount in the first payment is $297.50 (calculated above as 8.5% of the $3,500 loan amount)

The choices do not match this:

A. $297.50 - This is the correct choice. This is the interest amount paid over the full loan.

B. $291.67 - This is too low. Calculated interest over 1 year at 8.5% is $297.50.

C. $24.79 - This is way too low. The interest amount due is $297.50 per the working.

D. $35.00 - This is also too low and does not make sense based on the loan details provided.

In summary, to find the interest in just the first payment, we calculate:

Interest over full loan ($297.50) / Number of payments (12) = $24.79

So the interest amount in just the first monthly payment is $24.79.

But the total interest paid over the life of the loan (1 year) is $297.50.

We would need to study 678 families to determine the market preference for baby shampoo brands with a 96% confidence level and 4% margin of error, given that there are 12,000 families with babies in the sector of interest.

To calculate the sample size needed to determine the market preference for baby shampoo brands, we can use the formula:

n = [(Z^2 * p * q) / E^2]

where:

n = sample size

Z = Z-score for the desired level of confidence (in this case, 1.96 for a 96% confidence level)

p = proportion expected (in this case, 0.12 or 12%)

q = 1 - p

E = margin of error (in this case, 0.04 or 4%)

Substituting these values into the formula, we get:

n = [(1.96^2 * 0.12 * 0.88) / 0.04^2] = 677.16

Since we cannot have a fraction of a family, we round up the sample size to 678 families.
