Answer:
32
Step-by-step explanation:
simplify 24/3 = 8 then (24 / 4) * (2) = 48/8 = 6 = 6/8 = 3/4 we need to divide 24 by 3/4 = 32 or show 24 * 3/4 = 32 32 * 3/4 = 24
1) Of the last 100 people who failed the lie detector test, 23 turned out to be telling the truth. What is
the probability that the next person who fails the test is actually telling the truth?
A) 0.23
B) 0
C) 0.5
D) 0.77
Oh
The probability of those telling the truth is an illustration of experimental probability.
The probability that the next person tells the truth is 0.23
The given parameters are:
[tex]\mathbf{n = 100}[/tex] -- sample size
[tex]\mathbf{x = 23}[/tex] -- those telling the truth
So, the probability that the next person tells the truth is:
[tex]\mathbf{Pr = \frac xn}\\\\\\[/tex]
Substitute values for x and n
[tex]\mathbf{Pr = \frac{23}{100}}[/tex]
Divide 23 by 100
[tex]\mathbf{Pr = 0.23}[/tex]
Hence, the probability that the next person tells the truth is 0.23

Answer:
Slope = -1 . Parallel lines have the same slope. The slope is a coefficient of the x-term.
Step-by-step explanation:
y - x = 5
y = x + 5 slope = 1
The slope of the line parallel to the given line is 1.
What is slope?Slope is a value that describes the steepness and direction of a line. In variable format, it is commonly represented by the letter m.
The slope of a line is also called its gradient or rate of change. The slope formula is the vertical change in y divided by the horizontal change in x, sometimes called rise over run.
Given that the equation of a line y - x = 5, we need to find the slope of the parallel to the same,
Converting the equation in slope-intercept form,
y - x = 5
y = x + 5
Comparing with standard form of the equation of the line y = mx + c, where m is the slope,
Hence, the slope of the given line is 1,
We know that the slopes of the parallel lines are equal.
So, the slope of the asked line is 1.
Hence, the slope of the line parallel to the given line is 1.

6. The cost C of hiring a taxi is given by the formula C = 4 + 1.25m where m is the number of miles driven. Make a table showing the cost of hiring the taxi to drive 1, 2,3, and 4 s, Dete whether the cost of the taxi is proportional to the number of miles driven. Explain your reasoning.
The ratios are not all equal, we can conclude that the cost of the taxi is not proportional to the number of miles driven.
What is proportional?
A proportion is an equation in which two ratios are set equal to each other. For example, if there is 1 boy and 3 girls you could write the ratio as 1 : 3 (for every one boy there are 3 girls) 1 / 4 are boys and 3 / 4 are girls. 0.25 are boys (by dividing 1 by 4)
To find the cost of hiring a taxi to drive 1, 2, 3, and 4 miles, we can use the formula:
C = 4 + 1.25m
For m = 1, we have:
C = 4 + 1.25(1) = 5.25
For m = 2, we have:
C = 4 + 1.25(2) = 6.5
For m = 3, we have:
C = 4 + 1.25(3) = 7.75
For m = 4, we have:
C = 4 + 1.25(4) = 9
So the table of costs for driving 1, 2, 3, and 4 miles is:
Miles (m) Cost (C)
1 5.25
2 6.5
3 7.75
4 9
To determine whether the cost of the taxi is proportional to the number of miles driven, we can check whether the ratios of cost to distance are equal. If they are, then the cost is proportional to the number of miles driven.
Let's check the ratios:
C(1)/1 = 5.25/1 = 5.25
C(2)/2 = 6.5/2 = 3.25
C(3)/3 = 7.75/3 = 2.58333...
C(4)/4 = 9/4 = 2.25
Hence, the ratios are not all equal, we can conclude that the cost of the taxi is not proportional to the number of miles driven.

The formula is

3) d = 1.8
4) a₈ = 66
5) a) 138
b) 55
c) [tex]a_n=55n+83[/tex]
Step-by-step explanation:
Question 3
The common difference of an arithmetic sequence is the difference between consecutive terms.
Therefore, to find the common difference, subtract one term from the next:
⇒ d = 5 - 3.2
⇒ d = 1.8
Question 4
Given arithmetic sequence: [tex]a_n=10n-14[/tex]
To find the 8th term, substitute n = 8 into the equation:
[tex]\implies a_8=10(8)-14[/tex]
[tex]\implies a_8=80-14[/tex]
[tex]\implies a_8=66[/tex]

There are 20 dogs at the park on a busy Saturday.
9 of them are springer spaniels, 7 of them are labs
and 4 of them are bulldogs. What is the
probability that a randomly selected dog in not a
springer spaniel?
We know that 9/20 dogs are spaniels, so 11/20 of the dogs will not be spaniels. That would be your probability in fraction form, but if you need percentage, remember that you can find percentage of something by multiplying the fraction by 100 and evaluating, so [tex](\frac{11}{20} )*100= 0.55*100= 55[/tex]. So, the percentage of dogs that are not spaniels would be 55%.

Subtract 200 from both sides
2x = -20
divide both sides by 2
x = –10

Answer:
a. Her monthly payment is $1618.786418
b. She will pay $312763.1105 interest over the life of the loan
Step-by-step explanation:
Let us revise the rules of the monthly payments and interest
Where:
M.P is the monthly payment
P is the initial value
r is the interest rate in decimal
n is the period
t is the time
∵ Lynn bought a $300,000 house
∵ She was paying 10% down
→ That means the initial amount is 90% of $300,000
∴ p = 90/100 × 300,000 = 270,000
∵ She was financing the rest at 6%
∴ r = 6% = 6/100 = 0.06
∵ There is a monthly payment
∴ n = 12
∵ She was financing the rest for 30 years
∴ t = 30
a.
→ Substitute these values in the first rule to finding the monthly payment
∵
→ Let us use the calculator to find the answer
∴ M.P = $1618.786418
∴ Her monthly payment is $1618.786418
b.
→ Substitute these values in the first rule to finding the second rule
to find the interest
∵
→ Let us use the calculator to find the answer

Answer:
a. h < 79; w < 295
b. (h, w) = (60, 280)

Step-by-step explanation:
a.We can define h and w to represent the height in inches and the weight in pounds. Then the inequalities representing the given restrictions are ...
h < 79 . . . . . . . . height is less than 6'7"
w < 295 . . . . . . weight is less than 295 pounds
The graph is attached. The solution space is the area where the solutions to the inequalities overlap.
__
b.A 5 ft person weighing 280 pounds would meet the given restrictions.
(h, w) = (60, 280) . . . . is a possible solution
__
c.(50, 180) is a solution. The height of 50 inches is less than 79 inches, and the weight of 180 pounds is less than 295 pounds. (A person with these measurements would be quite obese.)
_____
Additional comments
As a practical matter, healthy 18-year-olds will generally have a height greater than 59 inches and a weight greater than 95 pounds. Less than 3% of the population will be shorter or lighter than that.
"Good physical condition" may require a body mass index within a certain range. This will put additional (rather narrow) limits on height and weight. We have only shown inequalities and a graph for the specific conditions listed in the problem statement.

In the given figure find the value of the unknown interior angle x in the following figure.
Answer:
Therefore, the measure of angles x is 70°.
Step-by-step explanation:
From the given figure ,
115° is the exterior angle
x° and 45° are the two interior opposite angles to 115°
We know that
An exterior angle formed by extending the side of a triangle is equal to the sum of the two interior opposite angles
⇛ x° + 45° = 115°
⇛ x° = 115°-45°
⇛ x° = 70°
Therefore , x = 70°
