the length of the minute hand on a clock
is 8 in . what is the circumference?

​

Answer:

If the data is symmetrical, then the mean is the best measure of central tendency to use, and the standard deviation is the best spread to use.

If the data is unsymmetrical, the median is the best measure of central tendency to use, and the inter-quarterly range is the best spread to use.

Step-by-step explanation:

An histogram for a symmetrical data will give a symmetrical shape, and the mean, median and mode will all be the same value. Therefore, the best measure of central tendency to use is the mean. The standard deviation shows how far away the values in a given data set are from the mean, and since the mean is used as the measure of central tendency in this case, the standard deviation should be used as the spread.

An histogram for a an asymmetric data set will give an asymmetric shape, and the mean is not always equal to the median. Therefore, the best measure of central tendency to use is the median. The inter-quarterly range shows the range of the middle 50% of a certain data, which is considered from the median value. Since the median is used as the measure of central tendency in this case, it is wise to use the inter-quarterly range as the measure of spread.

The simplified form of 13¹/3 + 2¹/3 - 10/2 is a fraction 64/6 that can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 2 the final answer is 32/3.

Given

13¹/3+2¹/3-10/2​

Required simplified it =?

First, we have simplified both constants separately

13¹/3 = (3 * 13 + 1) / 3 = 40/3

2¹/3 = (3 * 2 + 1) / 3 = 7/3

now the expression become = 40/3 + 7/3 - 10/2

now taking LCM of 3 and 2 which is 6.

                                                = 80/6 + 14/6 - 30/6

 now we have to simplify this fraction by dividing by 2 = 64/6

Therefore, the simplified form of 13¹/3 + 2¹/3 - 10/2 is 32/3.

Answer:

C. 6.67

Step-by-step explanation:

Given

Reserve Ratio (RR) = 15%

Required

Determine the simple deposit multiplier

Simple deposit multiplier (M) is calculated by taking the inverse of RR.

The following formula applies:

\(M = \frac{1}{RR}\)

Substitute 15% for RR

\(M = \frac{1}{15\%}\)

Convert 15% to decimal

\(M = \frac{1}{0.15}\)

\(M=6.67\)

Hence, option C answers the question

The slope of the tangent line to the function \(y=2x^2-5x\) at the point (-1, 7) is -9.

As per the question given,  

The derivative of a function represents its instantaneous rate of change or slope of the tangent line at any point on the function. To find the derivative of the given function, we can use the power rule, which states that the derivative of \(x^n\)is \(nx^{(n-1)}.\)

Applying the power rule to \(y=2x^2-5x\), we get:

\(y' = d/dx (2x^2-5x)= 4x - 5\)

Now we can evaluate this derivative at the given point (-1, 7) by plugging in x=-1:

\(y' = 4(-1) - 5= -9\)

Therefore, this means that if we were to draw a straight line tangent to the curve at that point, it would have a slope of -9. This information is useful for understanding the behavior of the function and its rate of change at that particular point.

Answer:

68% of the data points lie between 10 and 18.

Step-by-step explanation:

one standard deviation to left of mean = 14 - 4 =10

one standard deviation to right of mean = 14 + 4 = 18

68% of data is in this region.

so the answer is 68% of the data points lie between 10 and 18.

Below, you'll find a list of all the answers to the questions which are solved by using proportional relationship.

The general equation for a straight line is y=mx + c, where m represents the line's slope and expresses the rate of change of y per unit time with respect to x.

The point where the graph crosses the y-axis is called the y-intercept, or c.

Direct proportionality is also represented by y = mx. We can express m as follows: m = y/x

In our cafeteria, lemonade is made using a powdered drink mix. The quantity of water required to manufacture a certain amount of powdered drink mix is proportional to the number of scoops required. For every 2 scoops of mix, 1/2 gallon of water is required, and for every 5 scoops,

1 1/4 gallons of water are required.

The proportional formula is written as y = k x.

Using the information provided, we can now write: 2 scoops require 0.5 gallon of water.

1.25 gallon of water is required for 6 scoops.

This means that k = 2/0.5

k = 2/(1/2)

k = 2 x 2

k= 4

Equations describing the relationship can be expressed as y = 4x + c.

0.5 gallon of water is now required for 2 scoops.

2=4(1/2)+c

2=2+c

c=0

Therefore, the formula will be y = 4x.
