2y - 5(y-3) = 2y -5y - 15

                = -3y -15

Your welcome, and feel free to comment if you need have any questions!

The simplified value of the expression, 2y−5(y−3) using the Distributive property is 15- 3y.

Given Expression:

2y−5(y−3)

Using Distributive property

\({\text} a *(b+c) = (a *b) + (a*c)\)

So, applying the Distributive property in the expression  5(y - 3) gives

5(y - 3) = 5y - 15

Substituting the value 5y - 15 in 2y−5(y−3) as

2y−5(y−3) = 2y - (5y-15)

                 = 2y - 5y + 15

Now, operating the simplified value is

2y−5(y−3) = 15 - 3y

Thus, the simplified expression is -3y + 15.

Answer:

\(\frac{2}{3}\)

Step-by-step explanation:

Probability (P) is calculated as

P = \(\frac{number}{count}\)

Since P(eclair) = \(\frac{1}{15}\) and there are 3 eclairs, then original probability before simplification must have been

\(\frac{3}{45}\)

meaning the total number of sweets is 45, so

3 + 2x + 6 + x = 45

3x + 9 = 45 ( subtract 9 from both sides )

3x = 36 ( divide both sides by 3 )

x = 12

Then number of humbugs = 2x + 6 = 2(12) + 6 = 24 + 6 = 30

P(humbug) = \(\frac{30}{45}\) = \(\frac{2}{3}\)

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.

probability that a randomly selected point within the circle falls in the white area = degree occupied by white area / sum of angles in a circle

sum of angles in a circle = 360

degree occupied by white area = sum of angles in a circle - sum of degrees of shaded area

360 - (60 + 60) = 240

240 / 360

Data of different sizes can be easily arranged with histograms, but not with stem-and-leaf diagrams. This is a drawback.

Stem-and-leaf charts often include the original data values while histograms do not. This is a crucial advantage the former has over the latter.

The primary benefit of stem-and-leaf charts over histograms is that they display the original data values.

In contrast to stem-and-leaf charts, which lack this capability, histograms make it straightforward to organize data of various sizes. This is a serious disadvantage.

To determine the number of units that need to be sold to achieve an operating profit target of K500,000, we need additional information such as the contribution margin per unit and the fixed costs.

To calculate the number of units required to achieve an operating profit target, we need to consider the contribution margin per unit, which is the difference between the selling price per unit and the variable cost per unit. The contribution margin represents the amount available to cover fixed costs and contribute towards the operating profit.

Let's assume that the contribution margin per unit is C. The formula to calculate the breakeven point, where the operating profit is zero, is as follows: Breakeven Point (in units) = Fixed Costs / Contribution Margin per Unit To achieve an operating profit target of K500,000, we need to calculate the breakeven point and then add the desired profit to determine the total number of units that need to be sold. Let's assume the breakeven point is B and the desired profit is P. The formula to calculate the required sales volume is as follows:

Required Sales Volume (in units) = Breakeven Point + (Desired Profit / Contribution Margin per Unit) By plugging in the appropriate values, we can calculate the required number of units that need to be sold to achieve the operating profit target of K500,000. It's important to note that this calculation assumes a linear relationship between sales volume and profitability and does not take into account other factors such as market demand, pricing strategies, or potential economies of scale. Additionally, it's crucial to consider the accuracy and reliability of the available data used in the calculation to ensure the results are meaningful and actionable.

============================================

Explanation:

Use the slope and given point to find the y intercept

y = mx+b

8 = (-2/3)*(1) + b

8 = -2/3 + b

8 + 2/3 = b

24/3 + 2/3 = b

26/3 = b

b = 26/3

The equation of the line is y = (-2/3)x + 26/3

To confirm this, plug in x = 1 and we should get y = 8, due to the point (1,8)

y = (-2/3)x + 26/3

y = (-2/3)*1 + 26/3

y = -2/3 + 26/3

y = (-2+26)/3

y = 24/3

y = 8

So that verifies we have the correct equation.

--------------

Next, go through each answer choice to see if the x coordinate of the point leads to the y coordinate.

If we try x = 7, then,

y = (-2/3)x + 26/3

y = (-2/3)(7) + 26/3

y = -14/3 + 26/3

y = (-14+26)/3

y = 12/3

y = 4

This shows that (7,4) is on the line. Choice A is the answer

That rules out choice B.

----------------

If we tried x = -5, then,

y = (-2/3)x + 26/3

y = (-2/3)(-5) + 26/3

y = 10/3 + 26/3

y = 36/3

y = 12

meaning that (-5,12) is on the line. That rules out choices C and D.

Refer to the graph below. It visually confirms that of the four answer choices, only point A is on the line. I used GeoGebra to make the graph.

The golfer claims that his average score is less than 90.

Therefore, the null hypothesis is the opposite of what he claims

Null hypothesis \(H_{0}\) is average score \(u\) is greater than or equal to 90:

\(u \geq 90\)

\(H_{0} :u\geq 90\)

The function g(x) = (3x + 5) + 8 is a translation of 8 units upwards of f(x).

For a general function f(x), we define a vertical translation of N units as:

g(x) = f(x) + N

if N > 0, then the translation is upwards.

if N < 0, then the translation is downwards.

For a general function f(x), we define a horizontal translation of N units as:

g(x) = f(x) + N

if N > 0, then the translation is to the left.

if N < 0, then the translation is to the right.

Here we start at:

f(x) = 3x + 5

Function g(x) is:

g(x) = (3x + 5) + 8

g(x) = f(x) + 8

The recommended approach when choosing between one-tailed and two-tailed tests is to use a two-tailed test only.

The choice between a one-tailed or two-tailed test should be based on the research hypothesis and the specific question being investigated.

If you have a convincing reason for not predicting a direction, and use the one that is most likely to produce significant results.

If the research hypothesis or question does not make a clear directional prediction, then a two-tailed test would be appropriate.

This is because a two-tailed test will consider the possibility of significant results in both directions of the distribution.

And is more conservative in its estimation of significance.

If the research hypothesis or question does make a clear directional prediction, then a one-tailed test would be appropriate.

This is because a one-tailed test will only consider the possibility of significant results in one direction of the distribution.

And is more powerful in detecting significant results in that specific direction.

Therefore, the answer is to use a two-tailed test only if you have a convincing reason for not predicting a direction, and use the one that is most likely to produce significant results.

There are 144 ways to form a five-digit number that is divisible by 5 using the numerals 0, 1, 2, 3, 4, and 5 without repetition.

For the number to be divisible by 5, its units digit must be either 0 or 5. Since we cannot repeat digits, we have two cases to consider:

Case 1: The units digit is 0.

In this case, we have 5 choices for the units digit (0, 1, 2, 3, or 4). For the remaining four digits, we can choose them in 4! ways (i.e., 4 choices for the first digit, 3 choices for the second digit, 2 choices for the third digit, and 1 choice for the fourth digit).

Therefore, the total number of five-digit numbers that are divisible by 5 and have a units digit of 0 is:

5 × 4! = 120

Case 2: The units digit is 5.

In this case, we have only one choice for the units digit, which is 5. For the remaining four digits, we can choose them in 4! ways as before.

Therefore, the total number of five-digit numbers that are divisible by 5 and have a units digit of 5 is:

1 × 4! = 24

The total number of ways to form a five-digit number that is divisible by 5 without repeating digits is the sum of the numbers from both cases:

120 + 24 = 144

Therefore, there are 144 ways to form a five-digit number that is divisible by 5 using the numerals 0, 1, 2, 3, 4, and 5 without repetition.

Step-by-step explanation:

Geometric sequences are ones in which you multiply or divide to get the next terms in the sequence.

Cheers

The common ratio of a sequence must be the same to be geometric thus The sequences which are geometric are {16,-8,4,-2,1},{625,125,25,5,1} and {-15,-18,-21.6,-25.92,-31.104} thus option (B),(E) and (C) is correct.

A geometric progression is a sequence in which any element after the first is obtained by multiplying the previous element by a constant which is called a common ratio denoted by r.

For example, the sequence 1, 4, 16, 64,… is a geometric sequence with a common ratio of r = 4.

As per the given second option,

16,-8,4,-2,1

Common ratio -8/16 = 4/-8 = -2/4 = 1/-2

Therefore, it will be GP series.

Similarly {625,125,25,5,1} and {-15,-18,-21.6,-25.92,-31.104} will also be GP series.
