A. 30 kph
B. 225 kph
C. 232.5 kph
D. 7.5
Answers
Step-by-step explanation:
I hope u are asking for average speed
average speed = total distance/total time
= 225/7.5
= 30 km/h or 30 km per hour
Answer:
As Per Provided Information
Distance covered by his car 225 KmTime taken by his car 7.5 hoursWe have to determine the average speed of his car in kilometres per hour .
Using Formulae
\( \boxed {\bf \: Average\: Speed \: = \cfrac{Total \: Distance \: Covered}{ Total \: Time \: Taken }}\)
On substituting the value we get
\(\sf \qquad \: \longrightarrow\: Average\: Speed \: = \cfrac{225}{7.5} \\ \\ \\ \sf \qquad \: \longrightarrow\: Average\: Speed = \cancel \cfrac{225}{7.5} \\ \\ \\ \sf \qquad \: \longrightarrow\: Average\: Speed = 30km {h}^{ - 1} \)
Therefore,
Average speed of his car is 30 km/h .So your answer is A) 30 kph .

Work out an expression for the nth term
Please please answers this question ill give u like and mark as brainlist
Answers
Answer:
2n² + n
Step-by-step explanation:
Given sequence:
3, 10, 21, 36, ...
Work out the first differences between terms:
\(3 \underset{+7}{\longrightarrow} 10 \underset{+11}{\longrightarrow} 21 \underset{+15}{\longrightarrow} 36\)
As the first differences are not the same, work out the second differences.
\(7 \underset{+4}{\longrightarrow} 11 \underset{+4}{\longrightarrow} 15\)
As the second differences are the same, the sequence is quadratic and will contain an n² term.
The coefficient of n² is always half of the second difference. Therefore, as the second difference is 4, the coefficient of n² is 2.
To work out the nth term of the sequence, write out the numbers in the sequence 2n² and compare with the given sequence:
\(\begin{array}{|l|c|c|c|c|}\cline{1-5} n & 1 & 2 & 3 & 4 \\\cline{1-5} 2n^2 & 2 & 8 & 18 & 32\\\cline{1-5} \sf Operation & +1 & +2& +3& +4\\\cline{1-5} \sf Sequence & 3 & 10 & 21 & 36\\\cline{1-5}\end{array}\)

what is the rationale and basis for statistical process control? multiple choice question. results of previous corrective actions on the existing process acceptable variation within probability limits last month's quality metrics on process stability and how current month changed six sigma calculations and alpha error score
Answers
As per the concept of probability, the rationale behind statistical process control is to understand and control the sources of variation in a manufacturing process to change the six sigma calculations and alpha error score (option d).
Statistical Process Control (SPC) is a methodology used in manufacturing industries to monitor and control a process by measuring and analyzing the process variables over time.
The results of previous corrective actions on the existing process are important in determining the effectiveness of those actions and whether further adjustments are needed.
Acceptable variation within probability limits is a key aspect of SPC. By understanding the probability distribution of the process variables, we can determine the acceptable range of variation and use control charts to monitor the process and identify any deviations from this range.
Six sigma calculations and alpha error score are also important aspects of SPC. Six sigma is a statistical measure that indicates the level of quality in a process, and the alpha error score is the probability of rejecting a true null hypothesis.
Hnce the option (d) is correct.

Here are the errors associated with a particular forecast over the past 5 months, in chronological order: 2, 0, –5, 3, -8. In which month was the forecast perfectly accurate? In which month was the forecast the least accurate? In which month or months was the forecast too high?
Answers
The forecast was perfectly accurate in the second month, the least accurate in the fifth month, and too high in the first, second, and fourth months. The forecast errors for a particular forecast over the past 5 months were 2, 0, -5, 3, and -8.
To find the month when the forecast was perfectly accurate, we look for the month with a forecast error of zero. In this case, the second month had a forecast error of zero, so the forecast was perfectly accurate in that month.
To identify the month when the forecast was the least accurate, we look for the month with the largest absolute forecast error. In this case, the largest absolute forecast error is -8, which occurred in the fifth month. Hence, the forecast was the least accurate in the fifth month.
To determine the month or months when the forecast was too high, we look for the months with positive forecast errors. In this case, the first, second, and fourth months had forecast errors of 2, 0, and 3, respectively. Therefore, the forecast was too high in the first, second, and fourth months.

(Assume that the numbers cannot be used more than one time) - Does the order the numbers are entered matter? * Will all of the digut (0,1,2,3,4,5,6,7,8,9) be used? We should use
Answers
the probability of Joseph unlocking the phone on his first attempt is 1 out of 5,040, which can be expressed as the fraction 1/5040.
P2 = 2 and P6 = the order that spells LION. The question asks if the order matters and if all the letters will be used. To find the number of different ways four letters can be arranged, we should use the formula for permutations.
The formula for permutations is given by P(n, r) = n! / (n - r)!. In this case, we want to find the number of arrangements of four letters, so n = 4 and r = 4.
Substituting the values into the formula, we get P(4, 4) = 4! / (4 - 4)! = 4! / 0! = 4! / 1 = 4 × 3 × 2 × 1 / 1 = 24 / 1 = 24.
Therefore, there are 24 different ways to arrange the four letters.
As for Joseph finding a cell phone with a 4-digit code, the probability of him unlocking it on his first attempt depends on whether the order the numbers are entered matters and if all the digits (0, 1, 2, 3, 4, 5, 6, 7, 8, 9) will be used.
If the order matters, then there are 10 choices for the first digit, 9 choices for the second digit (since it can't be the same as the first), 8 choices for the third digit, and 7 choices for the fourth digit. Multiplying these choices together, we get 10 × 9 × 8 × 7 = 5,040 possible combinations.
If all the digits must be used, then there are 10 choices for the first digit, 9 choices for the second digit, 8 choices for the third digit, and 7 choices for the fourth digit. Multiplying these choices together, we get 10 * 9 * 8 * 7 = 5,040 possible combinations.

Emily rented a truck to move her belongings from her old apartment to her new apartment. The company charges a flat rental fee of $21.50 with an additional $0.50 for each mile driven. If the total cost was at most $121, how far did Emily drive to move her belongings to her new apartment?
A.
at least 199 miles
B.
at most 199 miles
C.
at least 60.5 miles
D.
at most 242 miles
Answers
The cost of renting the truck is $21.50, and she is charged an additional $0.50 for each mile driven. So, the total cost can be expressed as:
Total cost = $21.50 + ($0.50 * x)
According to the question, the total cost was at most $121. Therefore, we can write the inequality:
$21.50 + ($0.50 * x) ≤ $121
Now, let's solve for x:
$0.50 * x ≤ $121 - $21.50
$0.50 * x ≤ $99.50
x ≤ $99.50 / $0.50
x ≤ 199
So, Emily drove at most 199 miles. Therefore, the correct answer is B.
Answer:
B.
at most 199 miles
Step-by-step explanation:
To find how many miles Emily drove, we need to use the equation
Total cost = flat fee + miles driven * cost per mile
Substituting in the numbers
121 ≥ 21.50 + m * .5
121≥ 21.50 +.50m
Subtract 21.50 from each side.
99.50 ≥ .5m
Divide each side by .5
199 ≥m
Emily drove less than or equal to 199 miles

Answer:
Step-by-step explanation:
Since the square has 4 equal sides, we know the diagonal distance will be equal to the length of one side, so each side of the square = 3cm.
That means line CD = 3cm. Since we now know the length of two sides of the triangle and since the triangle is a right triangle (one angle is equal to 90°), we can now use the SOH CAH TOA property rules to solve for the angle next to theta. Since we have the opposite side and the hypotenuse side, we will use the sine function.
Sin∡ = opp / hyp
sin∡ = 3cm / 6 cm
Take the inverse sin function (there's a button on your calculator for this)
sin^-1 (3cm / 6cm) = 30°
Now, since we know a straight line is equal to 180°, we can use this to find theta.
Theta + ∡ = 180°
180°-∡ = theta
180° - 30° = 150°
The answer is b, theta = 150°

I need some explanation on how to do piece wise functions? Where do I even start with this equation, can you explain this step by step? Including breaking down the graphing of absolute functions?
Answers
A piecewise function is basically a function that behaves differently at different domain intervals.
The given piecewise function is
\(\begin{cases}2x\quad \quad \quad \quad \quad \quad x\le3 \\ \frac{1}{3}x^2-2x+9\quad x>3\end{cases}\)As you can see, the function has a different expression for the interval x is less than or equal to 3 and a different expression for the interval x is greater than 3.
The easiest way to determine which graph corresponds to the given piecewise function is to evaluate the piecewise function at different values of x and graph it.
Evaluate the piecewise function for the interval x is less than or equal to 3.
\(\begin{gathered} 2x \\ x=1\rightarrow2(1)=2 \\ x=2\rightarrow2(2)=4 \\ x=3\rightarrow2(3)=6 \end{gathered}\)Evaluate the piecewise function for the interval x is greater than 3.
\(\begin{gathered} \frac{1}{3}x^2-2x+9 \\ x=4\rightarrow\frac{1}{3}(4)^2-2(4)+9=6.33 \\ x=6\rightarrow\frac{1}{3}(6)^2-2(6)+9=9 \\ x=8\rightarrow\frac{1}{3}(8)^2-2(8)+9=14.33 \end{gathered}\)Now, let us graph these points
As you can see from the graph, it matches with the graph of the 2nd option.
Therefore, the correct graph of the given piecewise function is the 2nd graph.

Bob's golf palace had a set of 10 golf clubs that were marked on sale for $550. this was a discount of 30% off the original selling price. step 4 of 4 : what was the percent of profit based on the sale price? follow the problem-solving process and round your answer to the nearest hundredth of a percent, if necessary.
Answers
According to the question the percent of profit based on the sale price is approximately -42.85%.
To determine the percent of profit based on the sale price, we need to calculate the original selling price and the profit made from the sale.
Step 1: Calculate the original selling price:
Let's assume the original selling price is represented by "x".
Since the sale price is a 30% discount off the original selling price, we can write the equation:
x - 0.30x = $550
Simplifying the equation:
0.70x = $550
Dividing both sides by 0.70:
x = $550 / 0.70
x ≈ $785.71 (rounded to two decimal places)
Step 2: Calculate the profit:
Profit = Sale Price - Cost Price
Profit = $550 - $785.71
Profit = -$235.71 (negative value indicates a loss)
Step 3: Calculate the percent of profit based on the sale price:
Percent Profit = (Profit / Sale Price) * 100
Percent Profit = (-$235.71 / $550) * 100
Percent Profit ≈ -42.85% (rounded to two decimal places)
Therefore, the percent of profit based on the sale price is approximately -42.85%.

Darrin made t two-point basketball goals and one three point goal. if he made a total of 15 points, how many two point goals did he make?
Answers
Let's assume Darrin made x two-point goals. Each two-point goal contributes 2 points to the total score. Since he made t two-point goals, the total number of points contributed by the two-point goals is 2t.
Darrin also made one three-point goal, which contributes 3 points to the total score.
The total score is given as 15 points. So we can write the equation:
2t + 3 = 15
Simplifying the equation, we subtract 3 from both sides:
2t = 12
Finally, dividing both sides by 2, we find:
t = 6
Therefore, Darrin made a total of 6 two-point goals.

Answers
Answer:
x = 8
y = 36
Step-by-step explanation:
The triangle shown in the image is an isosceles triangle.
We can find the value of x using the above mentioned information:
∠B = ∠A
5x = 40 divide both sides by 5
x = 8
The sum of interior angles in a triangle is equal to 180°.
Since ∠B and ∠C are both 40°:
40 + 40 + 3y - 8 = 180 add/subtract like terms
72 + 3y = 180 subtract 73 from both sides
3y = 108 divide both sides by 3
y = 36
