Step-by-step explanation:

The ordered Pair that describes the location of M' is (-5,-1).

Given that a point M is located at (5,-1) on the coordinate plane and it is reflected over the y-axis to create point M'.

We know that when a point is reflected over the y-axis, the x-coordinate changes its sign. Hence the x-coordinate of M will become negative.

The formula for reflecting a point over y-axis is (x,y) → (-x,y)

Therefore, the coordinates of the new point M' would be (-5,-1).

Hence, the ordered pair that describes the location of M' is (-5,-1).

So, the correct option is D) (-5, -1).

The chance that the hospital will run out of sleeping pills on any given day is 0.5000 (or 0.5000 with four decimal places).

To calculate the chance that the hospital will run out of sleeping pills on any given day, we can use the normal distribution and Z-score.

First, let's calculate the Z-score using the formula:

Z = (X - μ) / σ

Where:

X = consumption rate per day (1,155 pills)

μ = average consumption rate per day (1,155 pills)

σ = standard deviation (81 pills)

Z = (1,155 - 1,155) / 81

Z = 0

Now, we need to find the probability associated with this Z-score. However, since the demand for sleeping pills can be considered continuous and not discrete, we need to calculate the area under the curve from negative infinity up to the Z-score. This represents the probability of not running out of sleeping pills.

We discover that the region to the left of a Z-score of 0 is 0.5000 using a basic normal distribution table or statistical software.

To find the probability of running out of sleeping pills, we subtract this probability from 1:

Probability of running out of sleeping pills = 1 - 0.5000

Probability of running out of sleeping pills = 0.5000

Therefore, on any given day, the hospital has a 0.5000 (or 0.5000 with four decimal places) chance of running out of sleeping tablets.

To maximize the expression 6xy² under the condition x + y = 72, we can use the method of substitution to rewrite the expression in terms of a single variable and find its maximum value. Since the second derivative at x = 96 is positive, x = 96 corresponds to the maximum value.

Given that x + y = 72, we can rewrite the expression 6xy² as 6x(72 - x)². Expanding this expression yields 6x(5184 - 144x + x²). Simplifying further gives us the quadratic expression 31104x - 864x² + 6x³.

To find the maximum value of this expression, we can take its derivative with respect to x and set it equal to zero. Taking the derivative yields 31104 - 1728x + 18x². Setting this equal to zero and solving for x gives us two critical points: x = 32 and x = 96.

To determine which critical point corresponds to the maximum value, we can evaluate the second derivative of the expression. The second derivative is -1728 + 36x. Plugging in x = 32 and x = 96 into the second derivative, we find that -1728 + 36(32) = -864 and -1728 + 36(96) = 1944, respectively. Since the second derivative at x = 96 is positive, x = 96 corresponds to the maximum value.

Charles Darwin predicted that tetrapods evolved from lobe-finned fishes. The observation that led to this hypothesis is the similarity of the limb structure of tetrapods to lobe-finned fish fins. He observed that the fin structure of the fish contained a similar bone pattern as the limb structure of tetrapods.

To support the hypothesis, the evidence that we can expect to find are fossils that have the transitional structures between the two organisms. We can also expect to find evidence of how the fins in fishes changed over time and how they evolved into the limb structures that we see in tetrapods. This could be in the form of fossils with intermediate stages between the two groups, showing how the structure of the fins changed over time and how that might have influenced the development of tetrapod limbs.

To find such fossils, we would look for rocks from the Devonian period, which lasted from around 419 to 359 million years ago. This is because this is the time period when tetrapods are believed to have evolved from lobe-finned fishes. It was during this period that the early tetrapod species such as Ichthyostega and Acanthostega evolved. As such, fossils of these early tetrapods and the fish they evolved from, as well as any intermediate fossils, would be most likely found in rocks from this time period.

96 ft/s toward home plate

Step-by-step explanation:

because I Know this because I actually teached a class about this

The velocity of the ball is 96.031 ft/second if a pitcher throws a baseball to home plate from a distance of 60.5 ft the ball reaches home plate in 0.63 seconds.

Distance is a numerical representation of the distance between two items or locations. Distance refers to a physical length or an approximation based on other physics or common usage considerations.

It is given that:

A pitcher throws a baseball to home plate from a distance of 60.5 ft the ball reaches home plate in 0.63 seconds.

The distance baseball traveled = 60.5 ft

Time it takes = 0.63 seconds

As we know, the distance-time relationship:

u = d/t

Here, u is the velocity

d is the distance

t is the time

u = 60.5/0.63

u = 96.031 ft/second

Thus, the velocity of the ball is 96.031 ft/second if a pitcher throws a baseball to home plate from a distance of 60.5 ft the ball reaches home plate in 0.63 seconds.

For the given problem, the area of ∆DEF is (1/9) x.

In the problem, we are given that ∆ABC is similar to ∆DEF with a scale factor of 1:3. This means that the corresponding sides of ∆DEF are three times longer than those of ∆ABC. Since the area of a triangle is proportional to the square of its side length, the area of ∆DEF will be proportional to the square of the scale factor, which is (1/3)^2 = 1/9.
Given that the area of ∆ABC is x, the area of ∆DEF can be found by multiplying the area of ∆ABC by the proportionality constant. Therefore, the area of ∆DEF is (1/9) x.
To summarize, the area of ∆DEF is (1/9) x, where x represents the area of ∆ABC. Thus, option A, (1/3) x, is the correct answer.

The interquartile range (IQR) is a measure of statistical dispersion, specifically the range between the first quartile (Q1) and the third quartile (Q3) in a dataset. To calculate the interquartile range for the given dataset (3, 4, 3, 9, 3, 5, 8, 5), we follow these steps:

Step 1: Arrange the dataset in ascending order: 3, 3, 3, 4, 5, 5, 8, 9.

Step 2: Calculate the median (Q2), which is the middle value of the dataset. In this case, the median is (4 + 5) / 2 = 4.5.

Step 3: Calculate the lower quartile (Q1), which is the median of the lower half of the dataset. In this case, the lower half is (3, 3, 3, 4), and the median of this subset is (3 + 3) / 2 = 3.

Step 4: Calculate the upper quartile (Q3), which is the median of the upper half of the dataset. In this case, the upper half is (5, 5, 8, 9), and the median of this subset is (5 + 8) / 2 = 6.5.

Step 5: Calculate the interquartile range (IQR) by subtracting Q1 from Q3: IQR = Q3 - Q1 = 6.5 - 3 = 3.5.

Therefore, the interquartile range for the given dataset is 3.5.

Step-by-step explanation:

The statement "the midpoint method is commonly used to compute elasticity because it gives the same answer regardless of the direction of change" is the correct option from the given options.

Generally, the midpoint method is used to calculate elasticity since it is not affected by the direction of change. As a result, the coefficient will be constant regardless of the direction of change.To calculate the slope of a straight line, the standard formula is used:

slope=change in y/change in x.

The slope of the line is the same whether we move from left to right or right to left because the numerator and denominator will have opposite signs, but the slope will always be the same.The same holds true for the concept of elasticity. Elasticity measures the responsiveness of one variable to changes in another variable. We use the same formula for the midpoint method:

elasticity=(change in Q/average Q)/(change in P/average P).

To compute elasticity, we must first determine the average values. The midpoint method calculates the elasticity by comparing two points, which is accomplished by taking the average of the two points. The denominator is the average price and quantity, which is the midpoint between the initial and final price and quantity. As a result, the numerator and denominator will have opposite signs, and the same elasticity will be calculated regardless of the direction of change.In contrast, using the standard method to calculate elasticity may yield differing results based on the direction of change. Because of the difference between the starting and ending points, the elasticity will be computed differently when moving from left to right versus right to left.

Thus, we can conclude that the midpoint method is commonly used to compute elasticity because it gives the same answer regardless of the direction of change.

Your monthly payment for the 60-month, 5.54% APR motorcycle loan to purchase your dream Harley-Davidson will be $136.88.

To calculate the monthly payment for a motorcycle loan, we can use the formula for the present value of an annuity. The formula is:

PMT = PV * r / (1 - (1 + r)^(-n))

Where:
PMT = Monthly payment
PV = Present value of the loan
r = Monthly interest rate
n = Number of months

In this case, the present value of the loan (PV) is $7,200, the monthly interest rate (r) is 5.54% divided by 12 (0.0554 / 12), and the number of months (n) is 60.

Plugging in these values into the formula, we get:

PMT = 7200 * (0.0554 / 12) / (1 - (1 + (0.0554 / 12))^(-60))

Evaluating this expression, the monthly payment comes out to be approximately $136.88.

Therefore, your monthly payment for the 60-month, 5.54% APR motorcycle loan to purchase your dream Harley-Davidson will be $136.88.

Answer:

The explicit formula is  [tex]a_{n}[/tex] = - 13 - 7n

Step-by-step explanation:

Let us at first find the type of the sequence

∵ The terms are - 20, - 27, - 34, - 41, ............

→ Find the difference between each to consecutive terms

∵ - 27 - (- 20) = - 27 + 20 = - 7

∵ - 34 - (- 27) = - 34 + 27 = - 7

∵ - 41 - (- 34) = - 41 + 34 = - 7

→ There is a constant difference between each two consecutive terms

∴ The sequence is Arithmetic

→ The explicit formula of the nth term of the arithmetic sequence is

∵ a = - 20

∵ d = -7

∴ [tex]a_{n}=-20+(n-1)(-7)[/tex]

→ Simplify it

∴ [tex]a_{n}[/tex] = - 20 + (-7)(n) - (-7)(1)

∴ [tex]a_{n}[/tex] = - 20 + (-7n) - (-7)

∴ [tex]a_{n}[/tex] = - 20 - 7n + 7

→ Add the like terms

∴ [tex]a_{n}[/tex] = (- 20 + 7) - 7n

∴ [tex]a_{n}[/tex] = - 13 - 7n

The explicit formula is  [tex]a_{n}[/tex] = - 13 - 7n
