A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Although the abbreviations "pct," "pct," and occasionally "pc" are also used, the percent sign, " percent ", is frequently used to signify it. A % is a number without dimensions and without a standard measurement.

Given

Thom's restaurant bill is $45

20 percent tip = 20 % of 45 = 20/100*45 = 9

Total cost =  Thom's restaurant bill + 20 percent tip

                = 45+ 9 = 54

Therefore, The total cost for Thom's meal is $54.

Answer:

The man should not buy the policy.

Step-by-step explanation:

A life insurance policy is a contract that pays a sum assured to a policy holder upon death, either immediately or at the end of year of death. The policy holder pays a premium amount in advance to cater for the future benefits (sum assured).

In the scenario presented, the man is 30 years old with a probability of 0.994 of survival with respect to mortality. The high probability of being alive through the year implies that the man is very unlikely to die and thus the probability of receiving the coverage amount is too minimal

Answer: The expected value is $400, so the man should buy the insurance policy.

Final answer:

The probability that Judy guesses at least 3 questions correctly in a multiple-choice test is calculated using the binomial probability formula. For the survey question, the hypergeometric distribution is used to find the probability of 4 or fewer out of 9 people entering a profession related to their major. Exact probabilities require mathematical computation.

Explanation:

Probability of Answering Multiple-Choice and Survey Questions Correctly

For question 1, we must calculate the probability that Judy guesses at least 3 questions correctly on a 7-question multiple-choice test, where each question has 4 possible answers. Since only one answer is correct per question, her probability of guessing a question correctly is 1/4. To find the total probability of answering 3 or more questions correctly, we use the binomial probability formula which considers the probability of success (1/4) and the number of trials (7 questions). We sum the probabilities of getting exactly 3, 4, 5, 6, or all 7 questions correct.

For question 2, regarding the survey of 300 college graduates, we use the hypergeometric distribution since the samples are taken without replacement. We need to determine the probability that 4 or fewer of the randomly selected 9 survey subjects entered a profession closely related to their college major. We know that 63% of the entire group, which is 189 individuals, entered a relevant profession. We sum the probabilities of 0, 1, 2, 3, and 4 people from our sample of 9 falling into the group who are working in their field.

The correct probabilities from the provided choices are not directly calculable without doing the necessary computations using the respective formulas for each scenario, which are beyond the scope of this response as we do not have the calculations or the respective formulas provided within the context of this interaction.

Answer:

538,650

Step-by-step explanation:

We must first find how many errors there will be if filed manually and if filed electronically

Manually: 2,700,000*20% or 2,700,000*.2

Answer: 540,000 errors

Electronically: 2,700,000*.05% or 2,700,000*.0005

Answer: 1,350 errors

We must then find the difference; 540,000-1,350=538,650

Answer:

538,650.

Step-by-step explanation:

Number of erroneous manual returns = 20% of 2.7 million

= 0.20 * 2,700,00 = 540,000.

Number for electronically returned =  2,700,000 * 0.0005 = 1350.

Difference = 540,00 - 1350 = 538,650.

h=20

Step-by-step explanation:

h=3 (V/lw)

h= 3 (960/12*12)

Answer:

110.9 sq ft

Step-by-step explanation:

split the equilateral triangle into two right triangles. use pythagorean theorem to discover that the height is about 13.86 ft. use the area formula, A= (1/2)bh

A=(1/2)(8)(13.86)= 110.9

Answer:

A =  64√2 ft² = approx. 90.5 ft²

Step-by-step explanation:

Because this is an equilateral triangle, the interior angles are also equal and are 60° each.  We'll use the area-of-a-triangle formula, A = (1/2)(b)(h), to find the area of this particular triangle.  We see from the diagram that the base is 16 ft.  

Drawing an imaginary line representing the height of this triangle, and letting h represent this height, we get

sin 60° = opp / hyp = h / (16 ft) = 1/√2, so that

 h        1

----- = -----

16      √2                              16

and so √2*h = 16, and h = -------

                                              √2

                                                                                        1      16     16

Then the area of this blue triangle is A = (1/2)(b)(h) = ---- * ----- * -------

                                                                                         2      1       √2

           128           128√2

or A = -------     = ------------ = 64√2 ft² = approx. 90.5 ft²

            √2               2

Answer:

The area of ABCD is 50 units²

The area IJKL is 80 units²

The area of QRST is 100 units²

The area of UVWX is 300 units²

Step-by-step explanation:

* Lets revise the area of the rectangle

- The area of any rectangle = its length × its width

- To solve the problem find the lengths of two adjacent sides and

  consider that one of them is the length and the other is the width

- Use the rule of the distance between two points (x1 , y1) and (x2 , y2)

 the distance = √[(x2 - x1)² + (y2 - y1)²]

# In rectangle ABCD

∵ A = (-9 , 8) , B = (-5 , 5) , C = (1 , 13)

∴ AB = √[(-5 - -9)² + (5 - 8)²] = √[(4)² + (-3)²] = √[16 + 9] = √25 = 5 units

∴ BC = √[(1 - -5)² + (13 - 5)²] = √[(6)² + (8)²] = √[36 + 64] = √100 = 10 units

∴ The area of ABCD = 5 × 10 = 50 units²

# In rectangle EFGH

∵ E = (30 , 20) , F = (39 , 29) , G (49 , 19)

∴ EF = √[(39 - 30)² + (29 - 20)²] = √[9² + 9²] = √[81 + 81] = √162 unit

∴ FG = √[(49 - 39)² + (19 - 29)²] = √10² + (-10)²] = √[100 + 100] = √200 units

∴ The area of EFGH = √162 × √200 = 180 units²

# In rectangle IJKL

∵ I = (-6 , 2) , J = (2 , 2) , K = (2 , -8)

∴ IJ = √[(2 - -6)² + (2 - 2)²] = √[8² + 0²] = √8² = 8 units

∴ JK = √[(2 - 2)² + (-8 - 2)²] = √[0² + (-10)²] = √10² = 10 units

∴ The area IJKL = 8 × 10 = 80 units²

# In rectangle MNOP

∵ M = (5 , 5) , N = (11 , 5) , O = (11 , -5)

∴ MN = √[(11 - 5)² + (5 - 5)²] = √[6² + 0²] = √6² = 6 units

∴ NO = √[(11 - 11)² + (-5 - 5)²] = √[0² + (-10)²] = √10² = 10 units

∴ The area of MNOP = 6 × 10 = 60 units²

# In rectangle QRST

∵ Q = (10 , 0) , R = (15 , 5) , S = (25 , -5)

∴ QR = √[(15 - 10)² + (5 - 0)²] = √[5² + 5²] = √[25 + 25] = √50 units

∴ RS = √[(25 - 15)² + (-5 - 5)²] = √[10² + (-10)²] = √[100 + 100] = √200 units

∴ The area of QRST = √50 × √200 = 100 units²

# In rectangle UVWX

∵ U = (0 , 5) , V = (15 , 20) , W = (25 , 10)

∴ UV = √[(15 - 0)² + (20 - 5)²] = √[15² + 15²] = √[225 + 225] = √450 units

∴ VW = √[(25 - 15)² + (10 - 20)²] = √[10² + (-10)²] = √100 + 100 = √200 units

∴ The area of UVWX = √450 × √200 = 300 units²

[tex]\textrm{0.01011}[/tex]

The probability of an incorrect result for the test to detect respiratory syncytial virus is calculated by considering the test's sensitivity and specificity, along with the prevalence of the virus in the population.

In order to calculate the probability that a randomly chosen person gets an incorrect result, we first need to understand how test accuracy works. Sensitivity refers to how often the test correctly identifies the presence of a disease when it is indeed there, while specificity refers to how often it correctly identifies the absence of a disease when it isn't there. In this case, the sensitivity is 97%, meaning it correctly identifies the virus in 97% of individuals who have the virus; the specificity is 99%, meaning it correctly identifies no virus in 99% of individuals who do not have the virus.

For the given population, 0.55% are infected. Hence, the probability of an incorrect result for a person with a virus is 3% (100% - 97%), and for a person without the virus is 1% (100% - 99%). Therefore, the total probability of getting an incorrect result is (0.55%/100 * 3%) + [(1 - 0.55%/100) * 1%].

When we substitute x=6 and y=-2 into the top equation we get,

2(6)-3(-2)=18

12+6=18

18=18

This is true. Hence the point satisfy the top equation.

But when we substitute x=6 and y=-2 into the bottom equation we get,

5(6)+3(-2)=3

30-6=3

24=3

Hence the bottom equation is not satisfied.

The first choice is correct.

Step-by-step explanation:

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The amount of money that is left with Lisa after buying tickets is $27.90.

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.

The total number of members in the family is 5 (Parents+2sisters+Lisa). Also, the cost of a single ticket in Atlanta is $14.42, therefore, the cost of five tickets will be,

The cost of 5 tickets = $14.42 × 5 = $72.10

The amount Lisa has to spend is $100, therefore, the money left with Lisa after buying the tickets is,

Amount left = $100 - $72.10 = $27.90

Hence, the amount of money that is left with Lisa after buying tickets is $27.90.

Answer:

[tex]P(B | A)=0.4=40\%[/tex]

Step-by-step explanation:

Call A to the event in which there are electrical storms.

Call B the event in which there is hail.

Then, by definition.

The Probability of B given A is:

[tex]P(B | A)=\frac{P(B\ and\ A)}{P(A)}[/tex]

We know that:

[tex]P(B\ and\ A)= 10\%=0.1\\\\P(A) = 25\%=0.25[/tex]

Therefore

[tex]P(B | A)=\frac{0.1}{0.25}[/tex]

[tex]P(B | A)=0.4=40\%[/tex]

The conditional probability of hail given thunderstorms is calculated using the formula P(Hail | Thunderstorms) = P(Thunderstorms and Hail) / P(Thunderstorms). Given the probabilities of 10% for thunderstorms with hail and 25% for thunderstorms, the result is a 40% probability of hail when thunderstorms are present.

The student is asking to find the conditional probability of hail occurring, given that thunderstorms are already happening. This is a probability question that involves understanding and applying the concept of conditional probability.

The probability of thunderstorms is given as 25% (or 0.25 in decimal form), and the probability of thunderstorms with hail is given as 10% (or 0.10 in decimal form). To find the probability of hail given thunderstorms, you use the formula for conditional probability which is P(Hail | Thunderstorms) = P(Thunderstorms and Hail) / P(Thunderstorms). The 'given' part is represented by the condition after the vertical bar '|', and the numerator is the probability of both thunderstorms and hail occurring.

Substituting the given values into the formula, we get P(Hail | Thunderstorms) = 0.10 / 0.25 = 0.40 or 40%. Therefore, if thunderstorms are occurring, there is a 40% probability that there is also hail.

Answer:

(0, 1)

Step-by-step explanation:

all of the points are the same number away: 2√5

Answer:

  (0, 1)

Step-by-step explanation:

A, B, and C are points on a circle. You are being asked to find the center of the circle. You can do that any of several ways.

I find it useful to plot the points on a graph. Doing so reveals that AB is perpendicular to BC, so ABC is a right triangle, and the center you want is the midpoint of the hypotenuse (AC).

  (A+C)/2 = ((2, -3) +(-2, 5))/2 = (2-2, -3+5)/2 = (0, 1) . . . . . coordinates of center

___

From a construction point of view, the center of the circle is the point of intersection of the perpendicular bisectors of the chords. In the attached, we have used a geometry program to draw the perpendicular bisectors of AB and BC. They meet at (0, 1).

___

From an algebra point of view, the points on the circle with center (h, k) and radius r satisfy the equation ...

  (x -h)^2 +(y -k)^2 = r^2

Filling in the point values, you get three equations in the three unknowns (h, k, r):

Finding the difference between any two pairs of these will result in two linear equations in h and k, so are easily solved.

  First - second: (4 -4h +h^2) +(9 +6k +k^2) -(16 -8h +h^2) -(9 -6k +k^2) = r^2 -r^2

  -12 +4h +12k = 0 . . . simplify

  h +3k = 3 . . . . . . . . . put in standard form

  Second -third: (16 -8h +h^2) +(9 -6k +k^2) -(4 +4h +h^2) -(25 -10k +k^2) = r^2 -r^2

  -4 -12h +4k = 0 . . . . simplify

  3h -k = -1 . . . . . . . . . put in standard form

Now, we can add 3 times the second of these equations to the first to find h:

  (h +3k) +3(3h -k) = (3) +3(-1)

  10h = 0

  h = 0

Then either of the equations can be used to find k = 1.

The center is (h, k) = (0, 1).

A scatter plot has a good fit when data points cluster near the line of best fit and show a clear positive or negative correlation, suggesting a strong relationship between variables. A bad fit is characterized by scattered data points with no apparent pattern and large residuals between the points and the line, indicating a weak or no correlation.

When a scatter plot has a good fit, it means that the line of best fit accurately represents the trend in the data. This line minimizes the distances, or residuals, between itself and all the points on the graph. You can tell if a scatter plot has a good fit if the data points form a pattern that closely follows the line of best fit, indicating that the variables have a strong correlation. Conversely, a bad fit is evident when the data points are widely scattered and do not follow a distinct pattern, suggesting a weak or no correlation between the variables.
