The total cost before the sales tax was 19.828 pounds.

For a party, Jordan purchased 3.8 pounds of turkey, 2.2 pounds of cheese, and 3.6 pounds of egg salad.

We have to determine the total cost before sales tax.

As per the question, we have prices as:

cost of turkey = 3.95 per pound

cost of egg cheese = 1.3 per pound

cost of egg salad = 0.89 per pound

The total cost of turkey = 3.8 × 3.95  = 15.01 pounds

The total cost of cheese = 2.2 × 1.3 = 2.86 pounds

The total cost of egg salad = 2.2 × 0.89 = 1.958 pounds

The total cost before sales tax = 15.01 + 1.958 +2.86

Apply the addition operation, and we get

The total cost before sales tax = 19.828 pounds

200 is the mean absolute deviation. Therefore, choice three (200) is the right one.

The absolute difference between the predicted and actual values must be determined, added together, and divided by the total number of periods.

Forecasted values are as follows: 1,500 and 1,400

Values in actuality: 1,200 and 1,500

Absolute differences:

|1,500 - 1,200| = 300

|1,400 - 1,500| = 100

Now, we calculate the MAD:

MAD = (300 + 100) / 2 = 400 / 2 = 200

Therefore, 200 is the mean absolute deviation. Therefore, choice three (200) is the right one.

Number of  different simple random samples of size 7 that can be selected from a population of size 10 = 480 ways

Stating the combination formula

The combination of an object is the method used in choosing the possible number of arrangements in an array of datasets.

The number of selections of a number n, taking r at a time is given by the formula: \(\frac{n!}{(n-r)!r!}\)

From the formula above, n is population size = 10

r is sample size = 7

Substituting the values of n and r

Number of  possible selections =  10!/(10 - 7)!*7! = 10!/3!*7!

= \(\frac{10\times9\times8\times 7! }{3 \times 2\times 1 \times 7!}\)

Answer:

3) if you were to draw vertical lines through this graph you would have instances where an 'x' value would have more than one unique 'y' value

Step-by-step explanation:

functions must have one unique 'y' value for each 'x' value

The third graph represent a relation that is not a function

A relation is a function if it has only One y-value for each x-value.

The third one doesn't represent a function, because for some values of "x", you get two different values for "y" (which should not happen, if that were a function).

In order to see it better, you can trace a vertical line onto that graph.

If that line and the graph intersects in more than one point, then that graph doesn't represent a function.

In every function, you must have a single "y" value for each "x" in the domain.

Hence, the third graph represent a relation that is not a function

The values of x and y will be predicted by finding the equation represented by the ordered pair

The equation of the ordered pair hence a linear equation will be of te form

y = mx + c

m = slope = (72 - 61) / (11 - 23)

m = 11 / -12

c. Probability of selecting a red card is 1/2 and odds is 1:1.

d. Probability of selecting a spade or a heart is 1/2 and odds is 1:1.

To compute the probability and odds of selecting each of the cards at random from a complete deck of 52 cards:

a. Probability of selecting a club:

There are 13 clubs in a deck of 52 cards.

So the probability of selecting a club is 13/52, which simplifies to 1/4 or 0.25.

The odds of selecting a club can be expressed as 1:3.

b. Probability of selecting an 8 or a 9:

There are four 8s and four 9s in a deck of 52 cards.

So the probability of selecting an 8 or a 9 is (4 + 4)/52 = 8/52, which simplifies to 2/13 or 0.154.

The odds of selecting an 8 or a 9 can be expressed as 2:11.

c. Probability of selecting a red card:

There are 26 red cards (13 hearts + 13 diamonds) in a deck of 52 cards. So the probability of selecting a red card is 26/52, which simplifies to 1/2 or 0.5.

The odds of selecting a red card can be expressed as 1:1.

d. Probability of selecting a spade or a heart:

There are 13 spades and 13 hearts in a deck of 52 cards.

So the probability of selecting a spade or a heart is (13 + 13)/52 = 26/52, which simplifies to 1/2 or 0.5.

Richard's net pay for the week, considering Social Security, Medicare, and FIT deductions, can be calculated by subtracting the total deductions from his gross earnings.

First, let's determine the amount deducted for Social Security. The Social Security rate is 6.2%, and the maximum earnings subject to this deduction are $118,500. Since Richard is $1,000 below the maximum level, the amount subject to Social Security deduction is $1,000. Therefore, the Social Security deduction is 6.2% of $1,000.

Next, we calculate the Medicare deduction. The Medicare rate is 1.45%, and it is applied to the entire earnings of $1,700.

To calculate the FIT deduction, we need additional information about Richard's taxable income, tax brackets, and exemptions. Without this information, we cannot provide an accurate calculation for the FIT deduction.

Finally, we subtract the total deductions (Social Security, Medicare, and FIT) from Richard's gross earnings of $1,700 to obtain his net pay for the week.

The difference between the height of the soap in the full dispenser and the height when 4,239 cubic centimeters of soap remains is 8.06 centimeters.

The volume of a cylinder is given by the formula V = πr²h, where V is the volume, r is the radius, and h is the height. We can rearrange this formula to solve for the height of the soap in the dispenser: h = V/(πr²) When the dispenser is full, the volume of the soap is 5,652 cubic centimeters and the radius is 7.5 centimeters.

Plugging these values into the formula, we get:

h = 5,652/(3.14 × 7.5²) h = 32.12 centimeters

When there are 4,239 cubic centimeters of soap remaining in the dispenser, the volume and radius are the same, so we can plug these values into the formula to find the new height:

h = 4,239/(3.14 × 7.5²)

h = 24.06 centimeters .

To find the difference between the height of the soap in the full dispenser and the height when 4,239 cubic centimeters of soap remains, we simply subtract the two heights: 32.12 - 24.06 = 8.06 centimeters

{00,01} is pairwise distinguishable by REP2. Any DFA recognizing REP2 must have at least four states. Every DFA recognizing REP k requires at least 2 k states. NFA recognizing REP k requires at least k states.

a) Distinguishing set method is an approach in computer science for finding the smallest deterministic finite automation (DFA) recognizing a given formal language.

Let REP 2 ={ww∣w∈{0,1}2}.

Given S={00,01,10,11},

show that S is pairwise distinguishable by REP 2.

Therefore, for each pair x, y∈S, a string z exists such that exactly one of xz and yz is in REP 2.

Let x, y∈S. Suppose that x≠y. We may assume, without loss of generality, that x=00 and y=01.

Let z=1. Then 00z=001∉REP2, while 01z=011∈REP2.

Hence, {00,01} is pairwise distinguishable by REP2.

Using a similar argument, one can show that each of the other three pairs in S is pairwise distinguishable by REP2.

b) To recognize REP2, a DFA with at least four states is required, since S has four elements, each of which must be distinguished from the others. Since S is pairwise distinguishable by REP2, any DFA that recognizes REP2 must also distinguish S. Therefore, any DFA recognizing REP2 must have at least four states.

c) Let k≥1, REPk={ww∣w∈{0,1}k}. Let A be a DFA recognizing REPk.

For all w∈{0,1}k, define q w =δ(q 0 ,w).

Since REPk is regular, there must be a path from the start state to an accepting state of A that spells each string w∈{0,1}k. But the state sequence from the start state to q w spells w twice, since ww∈REPk.

Therefore, if x≠y, then qx≠qy, since otherwise, either A would accept xw twice or A would accept yw twice. Since there are 2k strings of length k, A has at least 2k distinct states.

d) Suppose that N is an NFA recognizing REPk. Let w∈{0,1}k. Consider the sequence of states that N enters when it processes w, and let S be the set of distinct states in this sequence. Since |S|≤k, some state must be repeated in the sequence, say q i =q j

Yes, she can definitely use her van safety in one journey. The total weight is the weight of potatoes plus the weight of carots.

Given,

Number of sacks of potatoes = 30

Mass of each potato = 25

Total weight of Potatoes = 30 * 25

Number of sacks of carrots = 20

Mass of each Carot = 7.5

Total weight of Carrot = 20 * 7.5

(The total weight is the weight of potatoes plus the weight of carrots.)

So, total weight = 750 + 150
