The value of 'E' in the algebraic equation is -2

Algebraic equation is a mathematical statement in which two expressions are set equal to each other.

Therefore, let solve for 'E' in the equation 0.75(8+e)=2−1.25e

Use 0.75 to open the bracket

6 + 0.75e = 2 -1.25e

Collect the like terms

0.75e+1.25e = 2-6

2e = -4

Divide both sides by 2

2e/ 2 = -4/2

e =-2

Step-by-step explanation:

Let's denote the speed of each car as v, and the distance that Car A travels as d. Then we can set up two equations based on the information given:

d = v * (12/60) (since Car A reaches its destination in 12 minutes)

d + 4 = v * (18/60) (since Car B travels 4 miles farther than Car A and reaches its destination in 18 minutes)

Simplifying the equations by multiplying both sides by 60 (to convert the minutes to hours) and canceling out v, we get:

12v = 60d

18v = 60d + 240

Subtracting the first equation from the second, we get:

6v = 240

Therefore:

v = 240/6 = 40

So the cars travel at a speed of 40 miles per hour.

The slope of the line that represents the relationship between x and y is 3.33.

What is positive and negative slope?

The slope of a line, which in mathematics is a measure of how steep it is, is the ratio of the change in the y-coordinate to the change in the x-coordinate between two points on a line. In contrast to a line with a negative slope, which is travelling downhill from left to right, a positive slope line is moving uphill from left to right. The y-coordinate rises as the x-coordinate rises in a positive slope, whereas the y-coordinate falls as the x-coordinate rises in a negative slope, to put it another way.

The slope of the line is given as:

slope = (change in y) / (change in x)

Substituting the points (0, 0) and (0.3, 1).

slope = (1 - 0) / (0.3 - 0) = 1 / 0.3 = 3.33

Hence, the slope of the line that represents the relationship between x and y is 3.33.

The data is skewed to the bottom and contains an outlier.  

Step-by-step explanation:

1. Test for outlier

An outlier is a point that is more than 1.5IQR below Q1 or above Q3.  

IQR = Q3 - Q1 = 74 - 51 = 23

1.5 IQR  = 1.5 × 23 = 34.5

51 - 15 = 36 > 1.5IQR

The point at 15 is an outlier.

2. Test for normal distribution

The median is not in the middle of the box.  

Rather, it cuts the box into two unequal parts, so the data does not have a normal distribution.

3. Test for skewness

The longer part is to the left of the median, so the data is skewed left.

C) f is decreasing for x<0 because f′(x)<0 for x<0. , we can conclude that the function f is decreasing for x<0 because f′(x)<0 for x<0.

The derivative of f is f′(x)=x2−a2=(x−a)(x+a).

This implies that f′(x)<0 when x<−a or x>a. From the derivative, we can deduce that f is decreasing for x<0 because f′(x)<0 for x<0.

The derivative of the function f is f′(x)=x2−a2=(x−a)(x+a), where a is a positive constant. This means that the derivative is negative when x<−a or x>a. We can use this information to determine the behavior of the function. Since the derivative is negative when x is less than zero, we can conclude that the function f is decreasing for x<0 because f′(x)<0 for x<0.

SThe total number line will be less than n(2n+1).Here is the proven answer,

Defination of number line?

A number line is a visual representation of numbers, usually represented as a straight line, with zero in the middle and positive numbers to the right and negative numbers to the left.

Now the answer,

Let's start by experimenting with small values of n.

When n=1, we have 3 points and 3 lines connecting them. Therefore, n(2n+1) = 3, which is greater than the number of lines.

When n=2, we have 5 points and 10 lines connecting them. Therefore, n(2n+1) = 10, which is equal to the number of lines.

When n=3, we have 7 points and 21 lines connecting them. Therefore, n(2n+1) = 21, which is less than the number of lines.

Based on these examples, it seems that the number of lines we can draw is greater than n(2n+1) when n is small and less than n(2n+1) when n is large.

Now let's try to prove this statement. We can draw a line between any two points, so the total number of lines we can draw is equal to the number of pairs of points we can choose. The number of pairs of points we can choose from 2n+1 points is (2n+1) choose 2, which is equal to (2n+1)(2n)/2 = (2n^2+n).

Therefore, we need to show that (2n^2+n) < n(2n+1) for all positive integers n.

Expanding the right-hand side gives us n(2n+1) = 2n^2+n. So we need to show that (2n^2+n) < 2n^2+n for all positive integers n, which is clearly true.

The total number of lines we can draw is less than n(2n+1).

The temperature change in the coffee each minute :-

\( = - 54 \div 22\frac{1}{2} \)

\( = - 54 \div \frac{(2 \times 22 + 1)}{2} \)

\( = - 54 \div \frac{45}{2} \)

\( = - 54 \times \frac{2}{45} \)

In the given word problem, the rate of change is the change in the cost of the ice cream concerning the change in the number of scoops.

That is, the rate of change is the ratio of the change in the cost of ice cream and the change in the number of scoops. Let's first calculate the initial rate of change or slope of the given deal: When we buy a waffle cone, the cost is $3, and we can buy one scoop of ice cream for $1.50.So, for one scoop of ice cream, the total cost would be 3 + 1.50 = $4.50.

We can represent the cost of one scoop of ice cream with the help of a linear equation: y = mx + b. Here, the slope or the rate of change, m = Change in cost of ice cream/ Change in the number of scoops= 1.5/1= 1.5Therefore, the rate of change of the ice cream with respect to the number of scoops is $1.50/scoop.

To maintain a service level of 99%, we need a safety stock of 81.28 units, and the total cost (without the cost of the safety stock) is $10,753.62, taking into account both the ordering cost and carrying cost.

To calculate the safety stock, we need to use the formula: Safety stock = Z-score * standard deviation * square root of lead time. For a service level of 99%, the Z-score is 2.33. Plugging in the values, we get the safety stock to be 81.28 units.

To calculate the total cost, we need to consider the ordering cost and the carrying cost. The annual demand is 100 * 52 = 5200 units. The ordering cost is the hourly wage rate of $169 per order, so for a year, it would be 5200/EOQ * $169. The EOQ can be calculated as follows: square root of (2 * annual demand * ordering cost / carrying cost). Plugging in the values, we get the EOQ to be 202.09 units.

The carrying cost is $5 per unit, so for a year, it would be 5200/2 * 81.28 * $5. Adding the ordering cost and carrying cost, we get the total cost to be $10,753.62.

In summary, to maintain a service level of 99%, we need a safety stock of 81.28 units, and the total cost (without the cost of the safety stock) is $10,753.62, taking into account both the ordering cost and carrying cost.
