Complete the frequency table for the following set of data. =

The data points from the set of collected that are outside the [-2, 2] range means that the data is an outlier or unusual data

The z–score also known as standard score is the number of standard deviation a score is differs from the mean or average score

The z–score is given by the formula;

[tex]Z = \frac{x - \mu}{ \sigma} [/tex]

The Z–Score is therefore, the number of standard deviations, a data point, x is far from the mean, [tex] \mu [/tex]

The standard deviation, [tex] \sigma [/tex], is given by the formula;

[tex] \sigma = \sqrt{ \frac{ \sum {( x_{i} - \mu)}^{2} }{N} } [/tex]

As the value of [tex] \sigma [/tex] increases, the variability increases, and the Z–Score decreases, such that a Z–Score of less than -2 or greater than 2 are unusual.

From the z–score calculator, the probability that a data point has a z–score of less than -2 or more than 2 is 0.02275

Such a data point can be taken as an outlier

Therefore, data that is outside the [-2, 2] range is an unusual (outlier) data

With the full question now given (see attached image), I would allocate equal resources to Whole Milk and 0-1% fat milk. This exercise is about the Allocation of Resources in a free economy with the help of market trends. See further explanation below.

The allocation of available resources to diverse purposes is referred to as resource allocation in economics. In the framework of a whole economy, resources can be distributed through a variety of mechanisms, including markets and planning.

Note that in the attached graph, the demand for Whole Milk has been falling while the demand for 0-1% fat is dropping. While the reasons for this trend is beyond the scope of this exercise, suffice it to say that it is reasonably expected that the consumption data in 2001 will most likely be equal to each other.

1980 to 1985 the movement in 0-1% fat milk was negligible but it shot up the next 5 year period.

It is logical to expect that this pattern will reoccur since the demeand has been stable for the last 10 years (hence a reoccurring pattern).

On the other hand, every 5 years, the demand (consumption) for Whole Milk has consistently dropped. Hence the reason for the decision.

Answer: The answer is 5

Step-by-step explanation:

The given parallel lines have a transversal which passes through them.

Hence from the property of parallel lines we found the values of x and y as 16 and 10 respectively.

Given that two parallel lines are intersected by a transversal, pair of angles are created, such as:

angles that are vertically opposing and equal.

the related angle pairs that are equivalent.

the equal pairs of opposite exterior angles.

the opposite interior angle pairs that are equal.

From the diagram we have the alternate exterior angles which are equal.

Therefore, alternate angle 1 = (8x-14)°

and alternate exterior angle 2 = (5x+34)°

now equate them,

(8x-14)° =  (5x+34)°

8x-14=5x+34

8x-5x=34+14

3x=48

x=48/3

x=16

now substitute x value in angle 1:

8(16)-14

= 114°

therefore angle 1 = 180°-114°

= 66°

Hence (5y+16)° = 66

5y = 66-16

5y = 50

y = 50/5

y = 10

Therefore we get the values of x and y as 16 and 10 respectively.

Basketball should have 20.64 ft/s initial velocity.

When an object is moving, its velocity is the direction at which it is moving as a measure of how quickly its location is changing as seen from a certain point of view and as measured by a specific unit of time. velocity. It is the quickness, swiftness, or speed of movement, action, or operation. A measurement of a body's rate of motion in physics is the rate at which its location changes over time in a certain direction.

Given Data

The parabola y=(-16x2/0.434v2)+1.15x+8 can be used to represent the ath of a basketball through a hoop, where v is the ball's speed in feet per second, y is the hoop's height, and x is the distance from the hoop. When the basketball hoop is 10 feet high and 17 feet away, the following is true:

y = (-16x⁰.434v²)+1.15x+8

Answer:

a = 22, b = 6, c = 14, d = 8

Step-by-step explanation:

sum the elements in the leading diagonal , that is

7 + 15 + 23 = 45

then all other rows and columns and the other diagonal total 45

top row

7 + a + 16 = 45

23 + a = 45 ( subtract 23 from both sides )

a = 22

middle row

24 + 15 + b = 45

39 + b = 45 ( subtract 39 from both sides )

b = 6

left column

7 + 24 + c = 45

31 + c = 45 ( subtract 31 from both sides )

c = 14

bottom row

c + d + 23 = 45 , that is

14 + d + 23 = 45

37 + d = 45 ( subtract 37 from both sides )

d = 8

The mismatch in the number of variables in the ratio, implies that the ratio is undefined

The ratio expression is given as:

2 : 5 : 4 = n : 8

In the above ratio expression, we have the following observations:

If the ratio expression is to represent an equivalent expression, then the number of variables on both sides of the expression must be the same

This in other words implies that

When the number of variables on either sides of the ratio expression, then the ratio is either incorrect or undefined

In this case, we can conclude that the ratio is undefined

The equation of line in slope-intercept form is found as y = -3x + 7.

For the given question;

The two passing point of the line are;

(x1, y1) = (2,1)

(x2, y2) = (1,4)

Slope = m = (y2 - y1)/(x2 - x1)

Put the values.

m = (4 - 1)/(1 - 2)

m = -3

Then, the equation of the line in slope intercept form is found using two point equation.

y - y1 = m(x - x1)

y - 1 = -3(x - 2)

Simplifying,

y = -3x + 7

-3 is the slope and 7 is the y intercept.

Thus, the equation of line in slope-intercept form is found as y = -3x + 7.

If x represents the age of the youngest child, then the equation that models this scenario is x+3(x+4) = 5(x+2)-5 and the ages of the three sisters are 7, 9 and 11 years respectively.

According to the question,

We have the following information:

There sisters have ages that are consecutive odd integers. The sum of the age of the youngest and three times the age of the oldest is five less than five times the middle sister's age.

Age of youngest sister = x years

Middle sister = (x+2) years

Oldest sister = (x+4) years

Now, the equation according to the given situation is:

(a) x+3(x+4) = 5(x+2)-5

(b) Now, we can solve this equation:

x+3x+12 = 5x+10-5

4x+12 = 5x+5

12-5 = 5x-4x

x = 7

Middle sister = 7+2 = 9 years

Oldest sister = 7+4 = 11 years

Hence, the equation is x+3(x+4) = 5(x+2)-5 and their ages from the youngest to the oldest are 7, 9 and 11 years respectively.

What is linear equation?

A linear equation is one that may be written as a1x1+a2x2+......+anxn in mathematics, where a1, a2,...., an are the coefficients, which are frequently real integers. The coefficients, which may be any expressions as long as they don't contain any of the variables, can be thought of as the equation's parameters. The coefficients a1 to a must not all be 0 in order for the equation to have any sense. An alternative method for creating a linear equation is to equalize a linear polynomial over a field, from which the coefficients are drawn, to zero. The numbers that, when used to replace the unknowns in such an equation, result in the equality, are the solutions.
