Cara's new car holds 13.5 gallons of gas. If gas costs $2.98 per gallon, how much would it cost her to fill the gas tank from empty?
Thus, the total cost of gas for fill the tank of car tank is $40.23.
Explain about unitary method?Finding the sum of the values of one unit and then multiplying its amount by the sum of the values of one unit to get the value of even more or fewer units is the unitary method's formula. In this illustration, the "unit" represents the quantity of books, and the "value" is their purchase price.
When we visit the market to purchase any item, we inquire about the item's pricing from the shopkeeper. The term for this is unit price.
For the stated question:
Capacity of car = 13.5 gallons of gas.
Gas cost = $2.98 per gallon
So, cost to fill the tank:
Total cost = gas costs per gallon * Capacity of car
Total cost = $2.98 * 13.5
Total cost = $40.23
Thus, the total cost of gas for fill the tank of car tank is $40.23.

A hypothesis test is performed to determine if the proportion of all six packs of seltzers sold in a particular grocery store near a college campus that are alcoholic exceeds 50%. A random sample of 152 customers that purchased seltzer is acquired (assume no customer purchases more than one six pack at time, alcoholic or not); the sample proportion of these purchases that are alcoholic is obtained. From this sample a test statistic of 2.60 is calculated, which has a corresponding P-value of 0.0047.Which of the following is true?Select one:a. The probability the null hypothesis is true is 1-0.0047 = 0.9953.b. The probability that 50% of customers purchasing seltzers will be purchasing alcoholic seltzer on any given day is 0.0047.c. The probability that, in a random sample of 152 customers purchasing seltzers, more than 50% of those customers will have purchased alcoholic seltzer is 0.0047.d. None of these statements is true.e. The probability the null hypothesis is true is 0.0047.
If the hypothesis test is performed to determine if the proportion of all six packs of seltzers sold in a particular grocery store near a college campus that are alcoholic exceeds 50% Then complement of the P-value gives the probability that the null hypothesis is true, which is 1 minus 0.0047, or 0.9953.
The probability the null hypothesis is true is 1-0.0047 = 0.9953 because ,
The given P-value is 0.0047,
which is the probability of observing a test statistic as extreme as 2.60 or more extreme if the null hypothesis is true. Since this P-value is less than the significance level of 0.05 (assuming a typical significance level), we reject the null hypothesis and conclude that the proportion of all six packs of seltzers sold in the grocery store that are alcoholic exceeds 50%.
Therefore, statement (a) is true and all the other statements are incorrect. The complement of the P-value gives the probability that the null hypothesis is true, which is 1 minus 0.0047, or 0.9953.

Thus, a 0.1271 area under the standard normal curve corresponds to a z-score of roughly -1.14.
what is standard deviation ?The degree of variance or dispersion in a set of data values is measured by standard deviation. It computes the deviation of each data point from the mean (average) of the data. While a high standard deviation suggests that the data points are dispersed throughout a broader range of values, a low standard deviation suggests that the data points tend to be close to the mean. In statistics, the standard deviation is frequently used to evaluate the level of variability or dispersion within a data collection.
given
Using a normal distribution function on a calculator or a standard normal distribution table, we can determine the z-score that corresponds to an area of 0.1271 under the standard normal curve.
We can enter the following data into a calculator equipped with a normal distribution function:
Area = 0.1271
Mean = 0 (because we are using the usual normal distribution) (since we are using the standard normal distribution)
Standard deviation equals one (since we are using the standard normal distribution)
Calculating this, we obtain:
Z is equal to invNorm(0.1271, 0, 1) = -1.14.
Thus, a 0.1271 area under the standard normal curve corresponds to a z-score of roughly -1.14.

determine the system gain k so that the system will have a damping ratio of 0.5. for this value of k, find the rise time, settling time, and peak overshoot. assume that the system is subjected to a step input of 1v
A unity feedback control system is characterized by an open-loop transfer function G(s)H(s)=k/s(s+10). The system gain k so that the system will have a damping ratio of 0.5 is 4. The corresponding rise time is 2.3s, settling time is 4.4s, and peak overshoot is 0.26.
To determine the system gain k so that the system will have a damping ratio of 0.5, we can use the equation ζ=1/2ωn. Rearranging the equation yields k=2ωn2. Using the damping ratio of 0.5, this yields k=4.
For this value of k, the rise time, settling time, and peak overshoot can be determined using the following equations:
Rise Time: Tr=4.6/ωn
Settling Time: Ts=4.4/ζωn
Peak Overshoot: Mp=e^(-ζπ/√1-ζ^2)
Given that the damping ratio is 0.5 and the system is subjected to a step input of 1V, we can determine the rise time, settling time, and peak overshoot.
Rise Time: Tr=4.6/ωn=4.6/2=2.3s
Settling Time: Ts=4.4/0.5ωn=4.4/1=4.4s
Peak Overshoot: Mp=e^(-0.5π/√1-0.5^2)=0.26

a college student takes the same number of credits each semester. before beginning college, the student had some credits earned while in high school. after 2 semesters, the student had 45 credits, and after 5 semesters, the student had 90 credits. if c(t) is the number of credits after t semesters, write the equation that correctly represents this situation.
The equation that correctly represents this situation is c(t) = 45 + 45(t-2). This equation states that the total number of credits the student will have after t semesters is equal to 45 (the number of credits they had before beginning college) plus 45 times the number of semesters after two (t-2).
To explain this equation in more detail, we need to break it down. First, the student had some credits earned while in high school, so the equation starts off with c(t) = 45, which is the number of credits the student had before beginning college.
Next, 45(t-2) represents the number of credits earned in the additional semesters since college began. The t-2 part of the equation means that the total number of credits earned in the additional semesters starts at zero for t = 2. Then, for each additional semester, 45 credits are added. So, for example, when t = 5, 45 credits are added to the initial 45 credits the student had before beginning college, resulting in 90 credits.Therefore, the equation c(t) = 45 + 45(t-2) correctly represents this situation.

Naive Nelson uses RSA to receive a single ciphertext c, corresponding to the message m. His public modulus is n and his public encryption exponent is e. Since lie feels guilty that his system was used only once, he agrees to decrypt any ciphertext that someone sends him, as long as it is not c, and return the answer to that person. Evil Eve sends him the ciphertext 2°c (mod n). Show how this allows Eve to find m.
We have that, based on the system of the module, by sending Nelson 2ec (mod n), Eve can use her system to find m without ever sending him c.
How can we find the value?Naive Nelson's RSA system works using the equation c = me (mod n), where c is the recorded text, m is the message, e is the recorded exponent, and n is the public modulus. Therefore, to find m, Eve needs to solve the equation 2ec = me2 (mod n). Since 2e and m2 are known values, Eve can calculate more:
m = 2ec / m2 (module n)

Answer:
6.9 or 7.0 .
Step-by-step explanation:
*Note that ^2 means raised to the power of two or squared
a^2 + b^2 = c^2
The hypotenuse is always the C, and the leg can be either a or b.
Fill in the blanks with the numbers that we have:
Hypotenuse: 7.7 | Leg: 3.4
3.4^2 + b^2 = 7.7^2
Square the numbers given
3.4 x 3.4 = 11.56
7.7 x 7.7 = 59.29, which leads us to:
11.56 + b^2 = 59.29
To find what b equals, we need to subtract 11.56 from 59.29
59.29 - 11.56 = 47.73
b^2 = 47.73
We need to take the square root of 47.73 to find b. b and b^2 are two different things.
The square root of 47.73 is about 6.90869017977. It asks for the answer to be rounded to the nearest tenth, giving us 6.9 or 7.0.

Therefore, the probability of selecting the third chip as blue given that the first 2 chips were white is:
P(The third chip is blue the first 2 were white) = Number of ways / Total number of ways = 3 / 350 = 0.0086 (rounded to 4 decimal places)
c) P(The fourth chip is blue the first 2 were white):
The number of ways to select the first 2 white chips is given by:
Number of ways = (6C2) (5C0) (3C0) = 15
The number of ways to select the third chip as non-white given that the first 2 chips were white is given by:
Number of ways = (8C1) = 8
The number of ways to select the fourth chip as blue given that the first 2 chips were white, and the third chip was non-white is given by:
Number of ways = (3C1) = 3
Therefore, the probability of selecting the fourth chip as blue given that the first 2 chips were white is:
P(The fourth chip is blue the first 2 were white) = Number of ways / Total number of ways = 8*3 / 350 = 0.0686 (rounded to 4 decimal places)
Suppose we have a random variable X such that E[X]= 7 and E[X²] =58.
a) Determine the variance of X:
The variance of X is given by:
Var[X] = E[X²] - (E[X]) ²
Substituting the given values, we get:
Var[X] = 58 - (7) ² = 9

Graph the line with slope 3 passing through the point (1,-5),
Can somebody help me
Answer:
Step-by-step explanation:
To graph the line with slope 3 passing through the point (1,-5), we can use the point-slope form of the equation of a line, which is:
y - y1 = m(x - x1)
where m is the slope, and (x1, y1) is a point on the line.
Substituting the given values, we get:
y - (-5) = 3(x - 1)
Simplifying the equation, we get:
y + 5 = 3x - 3
Subtracting 5 from both sides, we get:
y = 3x - 8
Now we have the equation of the line in slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept. Comparing this equation to the one we just found, we can see that the slope is 3 and the y-intercept is -8.
To graph the line, we can plot the y-intercept at (0,-8) and then use the slope to find other points on the line. Since the slope is 3, we can go up 3 units and to the right 1 unit to find another point on the line. We can repeat this process to find more points on the line, and then connect them to graph the line.
suppose that 27.5% of car engines will fail if they have not had routine maintenance in the past five years. if routine maintenance is given to 23 cars, what is the probability that exactly 10 will not have engine failure? round your answer to six decimal places.
The probability that exactly 10 out of 23 cars will not have engine failure is 0.007638.
Step-by-step explanation: First, calculate the probability of an engine failing in five years with no routine maintenance, which is 27.5%. This can be written as a decimal, 0.275.Next, calculate the probability of an engine not failing in five years with routine maintenance. This probability is 100%-27.5% = 72.5%, written as a decimal 0.725.
Now, using the Binomial Distribution formula (nCr), calculate the probability of exactly 10 engines not failing out of 23 cars, where n = 23, r = 10 and p = 0.725. The equation would be [tex](23C10)*(0.725^{10})*(0.275^{13}) = 0.0076379904[/tex]
Finally, round the result to 6 decimal places, giving an answer of 0.007638.

You want the average rate of change of f(x) on the interval [-6, 5].
Average rate of changeThe average rate of change of function f(x) on the interval [a, b] is ...
AROC = (f(b) -f(a))/(b -a)
= (f(5) -f(-6))/(5 -(-6))
= (-20 -(-10))/5 +6 = (-20 +10)/(5 +6)
AROC = -10/11
The average rate of change on the interval is -10/11.

The set of all possible y-values for the function h constitutes its range. The range is therefore [-3, 0].
what is range ?The collection of all feasible output values (dependent variable) of a function is known as the range in mathematics. It is the totality of all possible numbers that the function can accept as input (an independent variable) and output. On the number line, the range is frequently represented by an interval or group of intervals. For instance, the range can be written as [-3, 3] if the domain of a function f(x) is [-2, 2] and its output numbers fall within [-3, 3].

Solve each absolute value inequality and show its solution set. l) −2x−5 ≤5
To solve this inequality, we must first isolate the absolute value on one side of the equation.
Step 1: Add 5 to both sides of the equation.
−2x−5 + 5 ≤ 5 + 5
Step 2: Simplify the left side.
−2x ≤ 10
Step 3: Divide both sides by -2.
x ≥ -5
Step 4: Graph the solution on a number line.
The solution set is {x | x ≥ -5}
