We want to find the slope for the following line:
[tex]\bf y=2x-9[/tex]
First, notice the form of the given equation is in slope intercept (y=mx+b) form. In this formula, m is the slope and b is the y-intercept. So to find the value of m, compare the equation to the slope int. formula.
[tex]\sf y=mx+b[/tex] ← formula
[tex]\sf y=2x-9[/tex] ← the slope is 2
>>> Therefore, the slope is 2.
Your consulting firm is submitting a bid for a big contract. From previous data, you know your firm has a 51% of successfully landing the contract. The agency to which you submitted your bid has asked for more information about your bid. Past experience indicates that for 70% of successful bids and 44% of unsuccessful bids, the agency asks for more information. (In other words, if you successfully bid, then the probability the agency asks for information is 70%, etc.) If an agency asks for more information, what is the probability the bid is successful
Answer:
P(S/A) = 0.6235
Step-by-step explanation:
Let's call S that you successfully bid, S' that you unsuccessfully bid, A that the agency asked for more information and A' that the agency didn't asked for more information.
So, the probability P(S/A) that the bid is successful given that the agency asks for more information is calculated as:
P(S/A) = P(S∩A)/P(A)
Where P(A) = P(S∩A) + P(S'∩A)
Then, the probability P(S∩A) that you successfully bid and the agency asked for more information is:
P(S∩A) = 0.51 * 0.7 = 0.357
Because your firm has a 51% of successfully landing the contract and if you successfully bid, then the probability the agency asks for information is 70%.
At the same way, the the probability P(S'∩A) that you unsuccessfully bid and the agency asked for more information is:
P(S'∩A) = (1-0.51) * 0.44 = 0.2156
So, P(A) and P(S/A) are equal to:
P(A) = 0.357 + 0.2156 = 0.5726
P(S/A) = 0.357/0.5726 = 0.6235

Assume that voltages in a circuit vary between 6 volts and 12 volts, and voltages are spread evenly over the range of possibilities, so that there is a uniform distribution. Find the probability of the given range of voltage levels. In each case, draw a sketch and leave answers as a fraction. a. Greater than 10 volts b. Less than 11 volts c. Between 6.5 volts and 8 volts
Answer:
a) [tex] P(X>10) =1-P(X<10) = 1-F(10) = 1-\frac{10-6}{12-6} = 0.333[/tex]
b) [tex] P(X<11)= F(11) = \frac{11-6}{12-6}= 0.833[/tex]
c) [tex] P(6.5<X<8)= F(8) -F(6.5) = \frac{8-6}{12-6}-\frac{6.5-6}{12-6}= 0.333-0.0833 = 0.250[/tex]
In the figure attached we have the illustration for the probability for each part.
Step-by-step explanation:
For this case we define the random variable X as the voltages in a circuit and the distribution for X is given by:
[tex]X \sim Unif (a= 6, b=12) [/tex]
Part a
we want this probability:
[tex] P(X>10)[/tex]
We can use the cumulative distirbution function given by:
[tex] F(x) = \frac{x-a}{b-a}, a\leq X \leq b[/tex]
And using the complement rule we have this:
[tex] P(X>10) =1-P(X<10) = 1-F(10) = 1-\frac{10-6}{12-6} = 0.333[/tex]
Part b
We want this probability:
[tex] P(X<11)[/tex]
And using the cumulative distirbution function we got:
[tex] P(X<11)= F(11) = \frac{11-6}{12-6}= 0.833[/tex]
Part c
We want this probability:
[tex] P(6.5<X<8)[/tex]
And using the cumulative distirbution function we got:
[tex] P(6.5<X<8)= F(8) -F(6.5) = \frac{8-6}{12-6}-\frac{6.5-6}{12-6}= 0.333-0.0833 = 0.250[/tex]
In the figure attached we have the illustration for the probability for each part.
To find the probability of a given range of voltage levels in a circuit, we need to determine the proportion of voltages that fall within that range. In this case, the range of voltages varies between 6 volts and 12 volts, and they are spread evenly. The probability of the voltage being greater than 10 volts is 1/3, the probability of the voltage being less than 11 volts is 5/6, and the probability of the voltage being between 6.5 volts and 8 volts is 1/4.
Explanation:To find the probability of a given range of voltage levels, we need to determine the percentage of voltage values that fall within that range. In this case, the range of voltages varies between 6 volts and 12 volts. Since the voltages are spread evenly, we can calculate the probability by finding the proportion of the range compared to the total range of possibilities.
Greater than 10 volts: To find the probability that the voltage is greater than 10 volts, we need to determine the proportion of voltages that fall above this threshold. Since the range is from 6 volts to 12 volts, the proportion of voltages greater than 10 volts is (12 - 10) / (12 - 6) = 2/6 = 1/3.Less than 11 volts: To find the probability that the voltage is less than 11 volts, we need to determine the proportion of voltages that fall below this threshold. Since the range is from 6 volts to 12 volts, the proportion of voltages less than 11 volts is (11 - 6) / (12 - 6) = 5/6.Between 6.5 volts and 8 volts: To find the probability that the voltage is between 6.5 volts and 8 volts, we need to determine the proportion of voltages that fall within this range. Since the range is from 6 volts to 12 volts, the proportion of voltages between 6.5 volts and 8 volts is (8 - 6.5) / (12 - 6) = 1.5/6 = 1/4.1. A rectangular tile has a decorative

Given the sequence:
25, 21, 17, 13,...
Write the explicit equation that models the sequence.
Answer:
The explicit equation that models the sequence is [tex]f(n)=25-4(n-1)[/tex].
Step-by-step explanation:
An arithmetic sequence is a list of numbers with a definite pattern. If you take any number in the sequence then subtract it by the previous one, and the result is always the same or constant then it is an arithmetic sequence.
The constant difference in all pairs of consecutive or successive numbers in a sequence is called the common difference.
In general, this is the standard explicit formula of an arithmetic sequence whose first term is A and common difference is B:
[tex]f(n)=A+B(n-1)[/tex]
The sequence {25, 21, 17, 13, ...} is an example of an arithmetic sequence the same number, -4, is subtracted to each term to get to the next term.
We know the first term is 25 and common difference is -4.
Applying the standard explicit formula of an arithmetic sequence we get that
[tex]f(n)=25-4(n-1)[/tex].
The explicit equation is aₙ = 29 - 4n
25, 21, 17, 13...….
The sequence follows an arithmetic sequence. Therefore,
common difference (d) = 21 - 25 = -4
first term(a) = 25
Therefore, the explicit equation can be represented below:
aₙ = a + (n - 1)d
aₙ = 25 + (n - 1)-4
aₙ = 25 - 4n + 4
aₙ = 29 - 4n

Choose the correct statement below. Parameter because the value is a numerical measurement describing a characteristic of a population. Statistic because the value is a numerical measurement describing a characteristic of a sample. Parameter because the value is a numerical measurement describing a characteristic of a sample. Statistic because the value is a numerical measurement describing a characteristic of a population.
Answer:
Parameter because the value is a numerical measurement describing a characteristic of a population.
Step-by-step explanation:
key word is, the study of all 4548 employees
The underlined number, 45%, is a parameter because it's a numerical measurement that describes a characteristic of an entire population (in this case, all 4548 employees at a college). If the data was from a subset of the population or a sample, then it would be a statistic.
Explanation:The underlined number 45% is a parameter because the value is a numerical measurement describing a characteristic of a population. In statistics, a parameter refers to a numerical characteristic of a population. In this case, the whole population under study is all 4548 employees at a college, and the underlined number represents the proportion of this entire population that owns computers.
To illustrate this concept further, consider a situation where you are studying a smaller group or sample from the entire population of employees. A statistic, on the other hand, would be a numerical measurement that describes a characteristic of this sample. If you were to evaluate a subset of 1000 employees from this college and found that 40% of them own computers, that would be a statistic because the value is describing a characteristic of a sample, not the entire population.
In summary, a parameter is a numerical characteristic of a whole population while a statistic is a numerical characteristic of a sample taken from that population.

10 170000 miles
360.555 miles
300 miles
412.310 miles
Answer: 412.310 miles
Step-by-step explanation:
The diagram representing the scenario is shown in the attached photo. The bearing is taken with respect to the northern direction. The angles at B are determined by applying the concept of alternate angles with respect to parallel lines.
A right angle triangle ABC is formed. The starting point is A and the end point is C. The distance, x between A and C represents the hypotenuse of the triangle.
We would determine x by applying Pythagoras theorem which us expressed as
Hypotenuse² = opposite side² + adjacent side²
x² = 400² + 100² = 170000
x = √170000
x = 412.310 miles

A cat is stuck on the roof If the ladder is 16 feet long and must be placed six feet long and must be placed six feet away from the building How high can the ladder reach up the building to help save the cat?
14.8 feet
22 feet
37.9 feet
220 feet
How did it get on the roof?
Answer:
The answer is A. 14.8 feet.
Explanation:
We can use the Pythagorean theorem to solve this problem.
The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
In this case, the ladder represents the hypotenuse, and the distance from the building and the height reached by the ladder represent the other two sides.
Let's denote:
- [tex]\( a \)[/tex] as the distance from the building to the base of the ladder (6 feet)
- [tex]\( b \)[/tex] as the height reached by the ladder up the building (what we need to find)
- [tex]\( c \)[/tex] as the length of the ladder (16 feet)
According to the Pythagorean theorem, we have:
[tex]\[ a^2 + b^2 = c^2 \][/tex]
Substituting the given values:
[tex]\[ 6^2 + b^2 = 16^2 \][/tex]
[tex]\[ 36 + b^2 = 256 \][/tex]
[tex]\[ b^2 = 256 - 36 \][/tex]
[tex]\[ b^2 = 220 \][/tex]
To find [tex]\( b \)[/tex], we take the square root of both sides:
[tex]\[ b = \sqrt{220} \][/tex]
Using a calculator, we find:
[tex]\[ b \approx 14.8 \][/tex]
So, the ladder can reach up to approximately 14.8 feet on the building to help save the cat.
Results of a poll of a random sample of 3003 American adults showed that 20% do not know that caffeine contributes to dehydration. The poll was conducted for the Nutrition Information Center and had a margin of error of ± 1.4%. (a) Does the margin of error take into account any problems with the wording of the survey question, interviewer errors, bias from sequence of questions, and so forth?
Answer:
Check the explanation
Step-by-step explanation:
The margin of error does not take into account any problems with the wording of the survey question, interview errors, bias from sequence of questions, and so forth.
The margin of error reflects the difference between p(sample proportion) and P(Population proportion).
The margin of error addresses sampling variability and does not cover errors from survey design or administration flaws. Issues like question wording or interviewer bias are separate from sampling error. These design-related problems are not included in the margin of error.
The margin of error in a poll typically accounts for the natural variability that comes from sampling a subset of the population, rather than the entire population. This means it does not include errors that may arise from problems such as the wording of the survey question, interview errors, or bias from the sequence of questions. These issues are related to the design and administration of the survey and not the sampling process, so they are not reflected in the reported margin of error.

Answer:
Volume, [tex]V=96.79\ \text{feet}^3[/tex]
Step-by-step explanation:
An artist creates a cone shaped sculpture for an art exhibit.
Height of sculpture is 8 feets
The circumference of base of the cone is 21.352 feet.
The base of a con is circular shaped. So,
[tex]2\pi r= 21.352[/tex]
r is radius of cone
[tex]r= \dfrac{21.352}{2\times 3.14} \\\\r=3.4\ ft[/tex]
The volume of cone shaped sculpture is given by :
[tex]V=\dfrac{1}{3}\pi r^2 h\\\\V=\dfrac{1}{3}\times 3.14\times (3.4)^2 \times 8\\\\V=96.79\ \text{feet}^3[/tex]
So, the volume of the sculpture is [tex]96.79\ \text{feet}^3[/tex].
Find the 54th term of the arithmetic sequence -7,-23,-39
Answer:
-855
Step-by-step explanation:
Find the 54th term of the arithmetic sequence -7,-23,-39
The first term is a_1 = -7
we see that the common difference = d = -23 - (-7) = -16
so the formula: a_n = (n- 1)*d + a_1
a_54 = (54 - 1)* (-16) + (-7)
a_54 = 53 *(-16) - 7 = -848 - 7 = -855
