Step-by-step explanation:

The mean absolute deviation (MAD) for the given data is 1/20. This means that, on average, each data point in the set differs from the mean by 1/20.

To find the mean absolute deviation (MAD) of a set of data, we need to calculate the average difference between each data point and the mean of the data set. Here's how we can calculate it for the given data:

Step 1: Find the mean (average) of the data set.

Mean = (1/4 + 5/8 + 3/8 + 3/4 + 1/2) / 5 = 2/5

Step 2: Calculate the difference between each data point and the mean.

Differences: |1/4 - 2/5|, |5/8 - 2/5|, |3/8 - 2/5|, |3/4 - 2/5|, |1/2 - 2/5|

Step 3: Calculate the absolute value of each difference.

Absolute Differences: 1/20, 1/40, 1/40, 1/20, 1/10

Step 4: Find the average of the absolute differences.

MAD = (1/20 + 1/40 + 1/40 + 1/20 + 1/10) / 5 = 1/20

The MAD provides a measure of the average amount of variation or dispersion in the data set. In this case, a MAD of 1/20 indicates that the data points are relatively close to the mean, with most values falling within 1/20 of the mean value.

Answer:

  (x, y) = (19, 20)

Step-by-step explanation:

The coefficients of y are opposites, so we can add the two equations to eliminate y.

  (-3x +8y) +(-5x -8y) = (103) +(-255)

  -8x = -152

  x = 19 . . . . . . . divide by -8

Substituting into the first equation, we have ...

  -3(19) +8y = 103

  8y = 160

  y = 20

The solution is (x, y) = (19, 20).

Answer:

He has 3 pigs and 5 chickens

Step-by-step explanation:

Because pigs have 4 legs and 3 pigs would be 12 legs and then chickens have 2 legs so 5 chickens times 2 would be 10. Therefore he has 3 pigs and 5 chickens

Answer:

The pattern is adding by consecutive odds.

Step-by-step explanation:

The first odd you start with is 3:

1 + 3 = 4

4 + 5 = 9

9 + 7 = 16

16 + 9 = 25

25 + 11 = 36

...

Note that each time you add, it is by consecutive odds, meaning that after 36, you are adding 13, then 15, etc.

The given statement is a reasonable probability model because it fulfills the 4 conditions of binomial distribution.

The conditions for binomial distribution are;

1: The number of observations n must be fixed.

2: Each observation must be independent.

3: Each observation must represent one of two outcomes ("success" or "failure").

4: The probability of "success" p must be the same for each outcome.

Now, we are given the statement;

Joey buys a Virginia lottery ticket every week. x is the number of times in a year that he wins a prize.

From that statement, we can tell that the number of observations is fixed at 52 weeks since a year is made up of 52 weeks.

Secondly, we can say that there could be success by winning a price or failure by not winning the price.

Each weekly observation is independent.

The probability is the same for each outcome.

Thus, we conclude that since it fulfills all the four conditions then it is a binomial model.

Answer:

  1,222,200

Step-by-step explanation:

A search using a computer program found ...

  5432 × 225 = 1,222,200

__

1000 mod 225 = 100

4 × 225 = 900

This suggests that if we have some number of thousands whose digits total 9, that we will have the number of interest. Of course, we can add 200 to some number of thousands with a digit total of 7. The smallest such digit total will be had with the number 1222 using the specified digits {0, 1, 2}. This gives rise to the result above: 1222×1000 +200 = 1,222,200. It also explains why moving the 1 to the right will also give a multiple of 225.

Answer:

The point does not lie on the line

Step-by-step explanation:

Find the slope of the equation with rise/run

This gets you -1/-1 = 1

The equation will be y = x + 3, given the y intercept at (0, 3)

Plug in the point (2, 6) to see if it works in the equation

6 = 2 +3

6 \(\neq\) 5

The point does not lie on the line

A mathematical equation is a formula that joins two statements and uses the equal symbol (=) to indicate equality. A statistical statement that shows the equality of two mathematical terms is known as an equation in algebra. For instance, the elements 6x + 6 and 12 are separated by an equal sign with in equations 6x + 6 = 12. The relationship between the two phrases on either side of either a letter is described by a mathematical formula. Often, there is only one variable, which also serves as the symbol. for instance, 4x – 4 = 0.

Here,

Given :

where c is total numbers of cans

=> c/2 + 68 = 200

=>  c + 136 = 400

=> c = 264

median = 75

See explanation below

Part 1:

To find the emadian, we can state the data on the dot plot of the science midterm scores:

60, 65, 65, 70, 70, 75, 75, 75, 80, 80, 85, 85, 90, 95, 100

Total number of data set = 15

median = (N+1)/2

N = 15

Median = (15+1)/2 =16/2 = 8

Median = 8th position in the data

The 8th number = 75

Hence, the median of the science midterm scores = 75

Part 2:

The process is to write out all the data on the plot.

Count the number of data.

Then apply the median formula

Or because it is an odd number, the middle number after listing it out is the median.

The middle number here is 75

The cost of 14 red peppers with the same unit rate is $8.4.

Given that, Sophia bought 9 red peppers for $5.40.

Unit rate can be defined as the ratio between two measurements with the second term as 1. It is considered to be different from a rate, in which a certain number of units of the first quantity is compared to one unit of the second quantity.

Part A:

Let the cost in dollars c to the number of red peppers p.

Now, c=9p

⇒ 9p=5.40

⇒ p=5.40/9

⇒ p=$0.6

Part B:

The cost of 14 red peppers

= 14×0.6

= $8.4

Therefore, the cost of 14 red peppers with the same unit rate is $8.4.

Using simple interest, it is found that:

a) The monthly payment will be of $222.57.

b) In total, the car will cost $18,251.9275.

c) $16,025.1775 will be paid in interest.

The amount of money accrued after t years, using simple interest, with an initial value of P and a decimal rate of r is given by:

\(A(t) = P(1 + rt)\)

In this problem:

Item a:

The amount of money accrued will be of:

\(A(6) = 12618.25[1 + 0.045(6)] = 16025.1775 \)

Payment over 6 x 12 = 72 months, hence, the monthly payment will be of:

\(m = \frac{16025.1775}{72} = 222.57\)

The monthly payment will be of $222.57.

Item b:

The total cost is composed by:

Hence:

\(T = 0.15(14845) + 16025.1775 = 18251.9275\(

In total, the car will cost $18,251.9275.

Item c:

The required value of x is 49.

A mathematical expression is a phrase that contains a minimum of two numbers or variables and at least one mathematical procedure. It is possible to multiply, divide, add, or subtract in arithmetic.

Simplifying the left side of the equation, we get:

x - (-1) = x + 1

So the equation becomes:

x + 1 = 50

Subtracting 1 from both sides, we get:

x = 49

Therefore, the value of x is 49.
