There are 48 different possible outcomes.

The total number of possible outcomes in a scenario like this is determined by finding the product of the number of possible outcomes for each individual event.

Independent events are events that are not affected by each other and have no influence on each other's outcome. The probability of two independent events occurring together is the product of their individual probabilities.

When flipping a coin, there are 2 possible outcomes (heads or tails).

When rolling a fair die with 4 sides, there are 4 possible outcomes (1, 2, 3, or 4).

When rolling a fair die with 6 sides, there are 6 possible outcomes (1, 2, 3, 4, 5, or 6).

To find the total number of possible outcomes, we multiply the number of outcomes for each event:

2 * 4 * 6 = 48

Therefore, there are 48 different possible outcomes.

Example 1: Pair of lines are parallel.

Example 2: Pair of lines are perpendicular.

Example 3: Pair of lines are not parallel nor perpendicular.

What is the slope of the line in the slope-intercept form of the line?

If y = mx + c line is given then 'm' represents the slope of the line. If any pair of lines are given and if they have the same value of the slopes then we can say that the given pair of lines will be parallel in nature and if the slope of the one line is the negative inverse of the other line then we can say that the pair of lines are perpendicular to each other.

For example 1:

      y = 3x + 4 and y = 3x +7

     The slopes of both lines are equal hence, these pair of lines are parallel.

For example 2:

     y = -4x + 1 and 4y = x + 3

    Here, the slope of one line is the negative inverse of the other line hence this pair of lines are perpendicular to each other.

For example 3:

     y = 2x - 5 and y = 5x -5

   In this, the slopes are not equal so we can say that the graph of this pair of equations is not parallel nor perpendicular.

For example 4:

     y = -1/3x + 2 and y = 3x - 5

     Here, the slope of one line is the negative inverse of the other line hence this pair of lines are perpendicular to each other.

For example 5:

     y = 3/5x - 3 and 5y = 3x - 10

    The slopes of both lines are equal hence, these pair of lines are parallel.

For example 6:

     y = 4 and 4y = 6

     The slopes of both lines are equal hence, these pair of lines are parallel.

For example 7:

     y = 7x + 2 and x + 7y = 8

     Here, the slope of one line is the negative inverse of the other line hence this pair of lines are perpendicular to each other.

For example 8:

     y = 5/6x - 6 and x + 5y = 4

    In this, the slopes are not equal so we can say that the graph of this pair of equations is not parallel nor perpendicular.

Hence,

Example 1: Pair of lines are parallel.

Example 2: Pair of lines are perpendicular.

Example 3: Pair of lines are not parallel nor perpendicular.

Example 4: Pair of lines are perpendicular.

Example 5: Pair of lines are parallel.

Example 6: Pair of lines are parallel.

Example 7: Pair of lines are perpendicular.

Example 8:  Pair of lines are not parallel nor perpendicular.

The probability is approximately 52.54% or 31/59 when randomly choosing an element from the given subarray.

The probability of randomly selecting an array element within the subarray A[[n/2]], A[[n/2] + 1], ..., A[n] depends on the size of the subarray and the total number of elements in the array. In this case, n is given as 59.

The subarray A[[n/2]], A[[n/2] + 1], ..., A[n] includes the elements starting from the middle element, A[29], up to the last element, A[59]. Since the array has 59 elements, the subarray consists of 31 elements.

To determine the probability, we divide the size of the subarray (31) by the total number of elements in the array (59). Therefore, the probability is given by 31/59.

In decimal form, this probability is approximately 0.5254, which can be expressed as a percentage as approximately 52.54%.

Answer:

£160

Step-by-step explanation:

£160 times 0.6 equals  £96

since  £96 is 60% of the original price since 40% was taken off

The price of the bicycle before decrease is obtained as  £160.

A percentage is a value that indicates 100th part of any quantity.

A percentage can be converted into a fraction or a decimal by dividing it by 100. And to convert a fraction or a decimal into percentage, they are multiplied by 100.

The new price of the bicycle is  £96.

And, the percent of decrease is 40%.

Suppose the original price be x.

Then, the following equation can be written for the given case as,

x - 40% × x = 96

⇒ x - 40/100x = 96

⇒ 60/100x = 96

⇒ x = 160

Hence, the original price of the bicycle is given as £160.

The probability of getting 0 toppings when ordering a hamburger with a choice of up to 6 toppings is 0.0154, rounded to four decimal places.

The total number of ways to choose 6 toppings out of a possible 6 is given by the combination formula:

\($${ \choose 6} = \frac{6!}{6!(6-6)!} = 1$$\)

This is the total number of possible outcomes.

To get 0 toppings, we need to choose 0 toppings out of 6. The number of ways to do this is:

\({6_{0} =\) \(\frac{6!}{0!(6-0)!} = 1$$\)

So the probability of getting 0 toppings is:

\($$P(\text{0 toppings}) =\)  \(\frac{number of ways to get 0 toppings}{total number of possible outcomes} $$\) \(\frac{1}{1} = 1$$\)

First, let us make x the subject.

\(\sf \frac{x+4}{4} =\frac{y+7}{7}\)

Use cross multiplication.

\(\sf 7(x+4)=4(y+7)\)

Solve the brackets.

\(\sf 7x+28=4y+28\)

Subtract 28 from both sides.

\(\sf 7x=4y+28-28\\\\\sf7x=4y\)

Divide both sides by 7.

\(\sf x=\frac{4y}{7}\)

Now let us find the value of x/4.

To find that, replace x with (4y/7).

Let us find it now.

\(\sf \frac{x}{4} =\frac{\frac{4y}{7} }{4} \\\\\sf \frac{x}{4} =\frac{4y}{7}*\frac{1}{4} \\\\\sf \frac{x}{4} =\frac{4y}{28}\\\\\sf \frac{x}{4} =\frac{y}{7}\)

400*2= 800 blue drops

If you are selling a stock at $13.95 per share, the sale amount can be calculated using the formula: Sale Amount = Number of Shares x Price per Share. For example, if you are selling 10 shares of the stock, the sale amount is 10 x $13.95, or $139.50.

To calculate the sale amount for a larger number of shares, say 100, you would multiply the number of shares (100) by the price per share ($13.95) to get the sale amount of $1,395.00. The sale amount is simply the total amount of money you would receive from selling the stock.The sale amount for any stock can be calculated by multiplying the number of shares by the price per share. This equation is useful for calculating sale amounts for stocks that are being sold at different prices. For example, if the stock is selling at $14.50 per share, the sale amount for 100 shares would be 100 x $14.50 = $1,450.00.The sale amount for any stock is an important figure to know, as it will tell you how much money you will receive from selling the stock.

  4A(7)/7 +B = 19

  A(7) -3B = 19

Adding 3 times the first equation to the second gives ...

  19A = 4(19) . . . . . simplify

  A = 4 . . . . . . . . divide by 19

A is 4, B is 3.

The derivative r'(t) of the vector function r(t) is < sin(4t) + 4tcos(4t), 2t, cos(5t) - 5tsin(5t) >

To find the derivative of the vector function r(t), we differentiate each component of the vector separately.

The given vector function is r(t) = < tsin(4t) , t^2 , tcos(5t) >

To find the derivative of the first component, we apply the product rule of differentiation. The derivative of tsin(4t) with respect to t is sin(4t) + tcos(4t) * 4.

For the second component, the derivative of t^2 with respect to t is simply 2t.

Similarly, for the third component, we apply the product rule to tcos(5t). The derivative of tcos(5t) with respect to t is cos(5t) - t*sin(5t) * 5.

Combining these derivatives, we get r'(t) = < sin(4t) + 4tcos(4t), 2t, cos(5t) - 5tsin(5t) > as the final answer.

The proportion of a normal distribution located between z = .50 and z = -.50 will be 38.2%.

We have,

A normal distribution located between z = 0.50 and z = -0.50,

So,

Now,

From the Z-score table,

We get,

The Probability corresponding to the Z score of -0.50,

i.e.

P(-0.50 < X < 0) = 0.191,

And,

The Probability corresponding to the Z score of -0.50,

i.e.

P(0 < X < 0.50) = 0.191,

Now,

The proportion of a normal distribution,

i.e.

P(Z₁ < X < Z₂) = P(Z₁ < X < 0) + P(0 < X < Z₂)

Now,

Putting values,

i.e.

P(-0.50 < X < 0.50) = P(-0.50 < X < 0) + P(0 < X < 0.50)

Now,

Again putting values,

We get,

P(-0.50 < X < 0.50) = 0.191 + 0.191

On solving we get,

P(-0.50 < X < 0.50) = 0.382

So,

We can write as,

P(-0.50 < X < 0.50) = 38.2%

So,

The proportion of a normal distribution is 38.2%.

Hence we can say that the proportion of a normal distribution located between z = .50 and z = -.50 will be 38.2%.
