A hypothesis can be differentiated from a theory because it is a specific prediction arising from the theory. The statement that is true is, a hypothesis can be differentiated from a theory because it is a specific prediction arising from the theory. A hypothesis is a suggested explanation of a phenomenon or observed data that is testable.

Hypotheses are more detailed, and are written to explain precisely what you think is going to occur in your research and the reason for that prediction. A hypothesis will be rejected if it does not fit the data, whereas a theory will be modified to fit the data.

A hypothesis is more like a forecast, and a theory is more like a law that explains how certain events operate. Thus, we can conclude that a hypothesis is a specific prediction arising from the theory.

Step 1

Step 2

we substitute into the formula

The equation of a line is y = 0

The correct way to find the terms of the sequence {B}, which represents the balance in James' account after each deposit, is by using option B. Multiply the balance of the previous month by the monthly interest rate to find the interest of this month. Then, add the deposit and the interest of this month found earlier to the balance of the previous month to determine the balance of this month.(option D)

In James' savings plan, the balance after the first deposit is $120, as he starts with $0. To find the balance after the second deposit, we multiply the previous balance ($120) by the monthly interest rate (0.0085), which gives us $1.02. Adding the deposit of $120 to this interest amount, we get $121.02 as the balance after the second deposit. Continuing this process, we find the following terms:

First deposit: $120

Second deposit: $121.02

Third deposit: $242.23

Fourth deposit: $364.69

Fifth deposit: $488.40

Each term is obtained by multiplying the previous month's balance by the monthly interest rate, adding the deposit amount, and summing it up. This approach reflects the compounding effect of interest on the account balance, resulting in an increasing balance over time.

Step-by-step explanation:

(a) To find the probability of selecting a blue ball, we need to consider the probabilities from both urns.

The probability of selecting the first urn is 1/2 since there are two urns and one is chosen at random. The probability of selecting a blue ball from the first urn is 6/20 (6 blue balls out of a total of 20 balls).

The probability of selecting the second urn is also 1/2. The probability of selecting a blue ball from the second urn is 12/19 (12 blue balls out of a total of 19 balls).

To find the overall probability of selecting a blue ball, we can use the law of total probability:

P(blue) = P(First Urn) * P(blue | First Urn) + P(Second Urn) * P(blue | Second Urn)

P(blue) = (1/2) * (6/20) + (1/2) * (12/19)

Simplifying the expression, we get:

P(blue) = 0.25 + 0.3158

P(blue) = 0.5658

To convert to a percentage, we multiply by 100:

P(blue) = 56.58%

(b) Given that the chosen ball is blue, we want to find the probability that it came from the first urn.

Using Bayes' theorem, we can calculate:

P(First Urn | blue) = (P(blue | First Urn) * P(First Urn)) / P(blue)

P(First Urn | blue) = (6/20 * 1/2) / 0.5658

P(First Urn | blue) = 0.15 / 0.5658

P(First Urn | blue) ≈ 0.2654

To convert to a percentage, we multiply by 100:

P(First Urn | blue) ≈ 26.54%

Answer

I know the answer to number 4 is No

Step-by-step explanation:

Because when you plug the coordinates (8,-44) into the equation y=-7x+6 it gives the wrong output of -50

Player B is the most consistent, with an IQR of 2. This means that 50% of their scores fell within the range of 3 to 5.

What is probability?

Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 means the event is impossible and 1 means the event is certain to happen

To determine which player was more consistent, we need to find the best measure of variability for the data. The two common measures of variability are range and interquartile range (IQR).

The range is the difference between the highest and lowest values in the data set. For Player A, the range is 6 - 1 = 5, and for Player B, the range is 11 - 1 = 10.

The interquartile range (IQR) is a measure of dispersion based on dividing the data into quartiles. It is calculated as the difference between the third quartile (Q3) and the first quartile (Q1).

To find the IQR for each player, we first need to find the quartiles.

For Player A:

Arrange the data in order: 1, 1, 2, 2, 2, 3, 3, 3, 6

Find Q1: (2 + 2) / 2 = 2

Find Q3: (3 + 3) / 2 = 3

Calculate IQR: Q3 - Q1 = 3 - 2 = 1

For Player B:

Arrange the data in order: 1, 1, 2, 4, 4, 5, 5, 5, 11

Find Q1: (2 + 4) / 2 = 3

Find Q3: (5 + 5) / 2 = 5

Calculate IQR: Q3 - Q1 = 5 - 3 = 2

Therefore, Player B is the most consistent, with an IQR of 2. This means that 50% of their scores fell within the range of 3 to 5. In contrast, Player A has an IQR of 1, indicating that 50% of their scores fell within the range of 2 to 3.

Therefore, we can conclude that Player B was more consistent than Player A.

2.29 is less than the MAD of 2.53, it would not be unlikely to get a box with 31 red pencils based on the MAD for the given data set.

To determine whether it would be unlikely to get a box with 31 red pencils based on the Mean Absolute Deviation (MAD) for the given data set, we first need to calculate the MAD.

Step 1: Calculate the mean of the data set

The given data set is: 22, 28, 30, 28, 35, 30, 28

The mean is calculated by adding up all the numbers and dividing by the total number of values:

Mean = (22 + 28 + 30 + 28 + 35 + 30 + 28) / 7 = 201 / 7 = 28.71 (rounded to two decimal places)

Step 2: Calculate the absolute deviations

The absolute deviation for each data point is calculated by finding the absolute difference between the data point and the mean:

|22 - 28.71| = 6.71

|28 - 28.71| = 0.71

|30 - 28.71| = 1.29

|28 - 28.71| = 0.71

|35 - 28.71| = 6.29

|30 - 28.71| = 1.29

|28 - 28.71| = 0.71

Step 3: Calculate the MAD

The MAD is the mean of the absolute deviations:

MAD = (6.71 + 0.71 + 1.29 + 0.71 + 6.29 + 1.29 + 0.71) / 7 = 17.71 / 7 = 2.53 (rounded to two decimal places)

Now, to determine whether it would be unlikely to get a box with 31 red pencils, we can compare 31 with the MAD. If the difference between 31 and the mean (28.71) is greater than the MAD (2.53), then it would be unlikely.

Difference = 31 - 28.71 = 2.29

Since 2.29 is less than the MAD of 2.53, it would not be unlikely to get a box with 31 red pencils based on the MAD for the given data set.

Answer:

Option (A) and Option (E)

Step-by-step explanation:

Length of a segment between two points \((x_1,y_1)\) and \((x_2,y_2)\) is given by,

Length = \(\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}\)

Length of the segment between J(-8, 1) and K(-5, 5) will be,

JK = \(\sqrt{(-8+5)^2+(1-5)^2}\)

JK = \(\sqrt{9+16}\)

JK = 5 units

Length of segment between the points P(2, 8) and Q(7, 3) will be,

PQ = \(\sqrt{(2-7)^2+(8-3)^2}\)

PQ = \(\sqrt{25+25}\)

PQ = \(5\sqrt{2}\) units

Length of segment between the points S(-3, -10) and T(3, -2) will be,

ST = \(\sqrt{(-3-3)^2+(-10+2)^2}\)

ST = \(\sqrt{36+64}\)

ST = 10 units

Step-by-step explanation:

The range of the sequence is \(8\).

Let's calculate the requested values for the given sequence \(x[n] = [2, 1, 4, 6, 5, 8, 3, 9]\):

a) Find the mean (average) of the sequence.

To find the mean, we sum up all the values in the sequence and divide it by the total number of values.

\[

\text{Mean} = \frac{2 + 1 + 4 + 6 + 5 + 8 + 3 + 9}{8} = \frac{38}{8} = 4.75

\]

Therefore, the mean of the sequence is \(4.75\).

b) Find the median of the sequence.

To find the median, we need to arrange the values in the sequence in ascending order and find the middle value.

Arranging the sequence in ascending order: \([1, 2, 3, 4, 5, 6, 8, 9]\)

Since the sequence has an even number of values, the median will be the average of the two middle values.

The two middle values are \(4\) and \(5\), so the median is \(\frac{4 + 5}{2} = 4.5\).

Therefore, the median of the sequence is \(4.5\).

c) Find the mode(s) of the sequence.

The mode is the value(s) that occur(s) most frequently in the sequence.

In the given sequence, no value appears more than once, so there is no mode.

Therefore, the sequence has no mode.

d) Find the range of the sequence.

The range is the difference between the maximum and minimum values in the sequence.

The maximum value in the sequence is \(9\) and the minimum value is \(1\).

\[

\text{Range} = \text{Maximum value} - \text{Minimum value} = 9 - 1 = 8

\]

Therefore, the range of the sequence is \(8\).

A. To save for her payout annuity with an ordinary annuity set up thirty years before her retirement, Holly Krech must make a monthly payment of $175.97.

B. If she sets up the ordinary annuity twenty years before her retirement, Holly Krech must make a monthly payment of $432.00.

To calculate the monthly payment for an ordinary annuity set up thirty years before retirement, we can use the formula for the present value of an ordinary annuity. Given the deposit amount of $218,437.048 and the total amount received from the annuity of $432,000, and solving for the monthly payment, we find that Holly must make a monthly payment of $175.97.

For an ordinary annuity set up twenty years before retirement, we use the same formula for present value. With the deposit amount and total amount received unchanged, we solve for the monthly payment, which comes out to be $432.00.

It's important to note that the monthly payment increases when the annuity is set up closer to the retirement date. This is due to the shorter time period available for saving, resulting in a higher required contribution to reach the desired payout amount.

Step-by-step explanation:

[1] Mass of evaporating dish #1: 36.190 g

[2] Mass of evaporating dish and original sample: 37.020 g

To calculate the mass of the original sample, we subtract the mass of the evaporating dish from the total mass:

Mass of original sample = Mass of evaporating dish and original sample - Mass of evaporating dish

Mass of original sample = 37.020 g - 36.190 g

Mass of original sample = 0.830 g

[3] Mass of evaporating dish after subliming NH4Cl(g): 36.550 g

To calculate the mass of NH4Cl(g), we subtract the final mass of the evaporating dish from the initial mass:

Mass of NH4Cl(g) = Mass of evaporating dish - Mass of evaporating dish after subliming NH4Cl(g)

Mass of NH4Cl(g) = 36.190 g - 36.550 g

Mass of NH4Cl(g) = -0.360 g (Note: The negative value indicates an error in measurement or calculation. Please double-check the data provided.)

To calculate the percent of NH4Cl (%), we use the formula:

Percent of NH4Cl = (Mass of NH4Cl(g) / Mass of original sample) * 100

Percent of NH4Cl = (-0.360 g / 0.830 g) * 100

Percent of NH4Cl = -43.37% (Note: The negative value also suggests an error. Please review the data carefully.)

Moving on to the determination of Sodium Chloride:

[4] Mass of evaporating dish #2: 41.63 g

[5] Mass of watch glass: 47.84 g

[6] Mass of evaporating dish #2, watch glass, and NaCl(g): 89.510 g

To calculate the mass of NaCl(g), we subtract the sum of the masses of the evaporating dish #2 and the watch glass from the total mass:

Mass of NaCl(g) = Mass of evaporating dish #2, watch glass, and NaCl(g) - (Mass of evaporating dish #2 + Mass of watch glass)

Mass of NaCl(g) = 89.510 g - (41.63 g + 47.84 g)

Mass of NaCl(g) = 89.510 g - 89.47 g

Mass of NaCl(g) = 0.040 g

To calculate the percent of NaCl (%), we use the formula:

Percent of NaCl = (Mass of NaCl(g) / Mass of original sample) * 100

Percent of NaCl = (0.040 g / 0.830 g) * 100

Percent of NaCl = 4.82%

Step-by-step explanation:

the second option.

you see that the steeper line has a slope of -3 (when x increases by 1 grid point, y decreases by 3 grid points, that makes the slope ratio of y/x = -3/1 = -3).

the slope is always the factor of x in an equation of

y = ax + b

the only equation provided in the answer options with slope -3 is

-y <= 3x + 4

because when we transform this into the general firm above, we need to multiply both sides by -1 (which flips the inequality symbol, by the way) :

y >= -3x - 4

there you have it. no other equation here can be transformed into this.

as a control we also look at the second equation :

-3x + 3y <= -9

3y <= 3x - 9

y <= x - 3

this has a slope of 1 (so, x and y both increase by the same amount), and the y-inteecept is -3 (the y value when x = 0). that also fits the graph.

so, it is all correct.
