A man cover 255 km in 6 hours on scooter at a uniform speed find his speed in kilometres per hour
Answer:
The man's speed is 42.5 km/h.
You can find this by dividing the distance he traveled (255 km) by the time it took him to travel that distance (6 hours).
255 km / 6 hours = 42.5 km/h.
The formula to find speed is:
Speed = Distance / Time
In this case, the distance is 255 km and the time is 6 hours. So using the formula, we can calculate the speed as:
Speed = 255 km / 6 hours = 42.5 km/h
So the man's speed is 42.5 km/h.
It takes Johnny 42 minutes to get to the zoo.After 18 minutes he stopped to get gas for his car .Write an equation to express how many more minutes he had to travel after getting gas
The equation to express how many more minutes he had to travel after getting gas is 42 - 18 = x.
What are the relation between time, distance, and speed?
The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time. In this example, distance is in meters (m) and time is in seconds (s), so the units will be in meters per second (m/s).
The equation to express how many more minutes Johnny had to travel after getting gas is:
42 - 18 = x
Johnny's total travel time to the zoo is 42 minutes
He stopped for 18 minutes to get gas for his car
To find out how many more minutes he had to travel after getting gas, we need to subtract the 18 minutes he spent getting gas from his total travel time.
This is represented by the equation 42 - 18 = x, where x represents the number of minutes he had left to travel after getting gas.
Hence, The equation to express how many more minutes he had to travel after getting gas is 42 - 18 = x.

Answer:
1) Mean = $75812.50
Median = $74000
Mode = $73100
2) Mean = 24.5
Median = 24.33333...
Modal class = 29 - 33
Step-by-step explanation:
Definitions
The mode is the most frequently occurring data value.The median is the middle value when all data values are placed in order of size.The mean is the sum of all data values divided by the total number of data values.Question 1Given data:
71500, 74900, 69700, 82300, 78500, 73100, 73100, 83400Mean
[tex]\begin{aligned}\textsf{Mean}&=\dfrac{71500+74900+69700+82300+78500+73100+73100+83400}{8}\\ &= \dfrac{606500}{8}\\&=75812.50\end{aligned}[/tex]
Median
Place the data values in order of size (smallest to largest):
69700, 71500, 73100, 73100, 74900, 78500, 82300, 83400As there is an even number of data values, the median is the mean of the middle two values:
[tex]\implies \sf Median=\dfrac{73100+74900}{2}=74000[/tex]
Mode
The most frequently occurring data value is $73100. Therefore:
[tex]\implies \textsf{Mode} = 73100[/tex]
Question 2With grouped data, we can only estimate the mean and median.
Mean
To find an estimate of the mean, assume that every reading in a class takes the value of the class midpoint.
The number of days is the frequency (f).
Add a class midpoint (x) and an fx column to the table:
[tex]\begin{array}{|c|c|c|c|}\cline{1-4}\vphantom{\dfrac12} \sf Number\;of\;sales&\textsf{Number of days, $f$}&\textsf{Class midpoint, $x$}&fx\\\cline{1-4}\vphantom{\dfrac12}14-18&5&16&80\\\cline{1-4}\vphantom{\dfrac12}19-23&9&21&189\\\cline{1-4}\vphantom{\dfrac12}24-28&6&26&156\\\cline{1-4}\vphantom{\dfrac12}29-33&10&31&310\\\cline{1-4}\vphantom{\dfrac12}\sf Totals&\sum f=30&&\sum fx=735\\\cline{1-4}\end{array}[/tex]
[tex]\textsf{Mean}=\dfrac{\sum fx}{\sum f}=\dfrac{735}{30}=24.5[/tex]
Median
To find an estimate for the median, use linear interpolation.
Add a cumulative frequency column to the table:
[tex]\begin{array}{|c|c|c|}\cline{1-3}\vphantom{\dfrac12} \sf Number\;of\;sales&\textsf{Number of days}&\textsf{Culmulative frequency}\\\cline{1-3}\vphantom{\dfrac12}14-18&5&5\\\cline{1-3}\vphantom{\dfrac12}19-23&9&14\\\cline{1-3}\vphantom{\dfrac12}24-28&6&20\\\cline{1-3}\vphantom{\dfrac12}29-33&10&30\\\cline{1-3}\end{array}[/tex]
Find which class the median is in.
Since n/2 = 30/2 = 15, there are 15 values less than or equal to the median. This means the median must be in the 24-28 class.
Therefore:
[tex]a_1=m-23.5[/tex][tex]b_1=28.5-23.5=5[/tex][tex]a_2=15-14=1[/tex][tex]b_2=20-14=6[/tex]To find the median, m:
[tex]\begin{aligned}\dfrac{a_1}{b_1}=\dfrac{a_2}{b_2} \implies \dfrac{m-23.5}{5}&=\dfrac{1}{6}\\\\ 6(m-23.5)&=5\\\\6m-141&=5\\\\6m&=146\\\\m&=24.3333...\end{aligned}[/tex]
Therefore, the median is 24.3333...
Mode
The modal class is the class with the highest frequency density.
As all the classes are the same width, this is the class with the highest frequency.

The perimeter of the shape is 51.42 cm
Calculate the value of the diameter d.
Take to be 3.142
TU
Answer:
The perimeter of a circle is equal 2 * pi * radius. So, if we let "d" be the diameter of the circle, we can use the following to solve for the radius:
Perimeter = 2 *p * radius = 51.42 cm
we can then use the relationship between the diameter and the radius to solve for the diameter:
d = 2 * radius
substitute the value of the perimeter equation into the diameter equation:
d= 2 * (51.42 cm / 2 * 3.142)
d= 33.49 cm
therefore, the diameter d is 33.49 cm

Jay Gatsby categorizes wines into one of three clusters. The centroids of these clusters, describing the average characteristics of a wine in each cluster, are listed in the following table. 1 2 8 Characteristic Cluster 2 3 7 Magnesium Flavanoids Proanthocyanins Colorintensity
Cluster 1 has average magnesium, flavanoids, and proanthocyanins levels, while Cluster 2 has low levels of these compounds, and Cluster 3 has high levels of these compounds. Colorintensity levels vary across clusters.
Cluster 1 has an average level of magnesium, flavanoids, and proanthocyanins. This means that the levels of these compounds are not particularly high or low. Cluster 2 has a lower level of these compounds than Cluster 1, so wines in this cluster would have a milder taste than Cluster 1. Cluster 3 has a higher level of these compounds than Cluster 1, resulting in a more intense flavor. The colorintensity of wines in each cluster can also vary, with darker or lighter wines depending on the cluster. Gatsby’s categorization system is based on these average characteristics, allowing him to determine the flavor and color of wines in each cluster.

SOLVE BY INDIRECT PROOF 1. If n – m is even, then n^2 – m^2 is also an even.2. If x is odd positive integer then x^2 – 1 is divisible by 4. 3. If x is an odd integer, then 8 is a factor of x^2 – 1. 4. Suppose x, y E Z. If x is even, then xy is even.
All statements can be proven by indirect proof. If the assumptions of the statement are false, the resulting contradiction proves that the initial assumption is wrong and the statement is true.
1. To prove this statement by indirect proof, assume that n – m is an even number but n^2 – m^2 is an odd number. Since n – m is even, it can be written as n – m = 2k, where k is an integer. This can be substituted into n^2 – m^2 = n^2 – (2k+m)^2 to create n^2 – m^2 = n^2 – 4km – m^2. Since both n and m are integers, 4km is an even number. This means that n^2 – m^2 is an even number, contradicting our assumption that it is an odd number. Therefore, our initial assumption is wrong, and n^2 – m^2 must be an even number if n – m is even.
2. To prove this statement by indirect proof, assume that x is an odd positive integer but x^2 – 1 is not divisible by 4. Since x is an odd positive integer, it can be written as x = 2k + 1, where k is an integer. This can be substituted into x^2 – 1 = (2k + 1)^2 – 1 to create x^2 – 1 = 4k^2 + 4k. Since both k and 4 are integers, 4k^2 is an even number. This means that x^2 – 1 is divisible by 4, contradicting our assumption that it is not divisible by 4. Therefore, our initial assumption is wrong, and x^2 – 1 must be divisible by 4 if x is an odd positive integer.
3. To prove this statement by indirect proof, assume that x is an odd integer but 8 is not a factor of x^2 – 1. Since x is an odd integer, it can be written as x = 2k + 1, where k is an integer. This can be substituted into x^2 – 1 = (2k + 1)^2 – 1 to create x^2 – 1 = 4k^2 + 4k. Since 8 is a factor of 4k^2, it is also a factor of x^2 – 1. This means that 8 is a factor of x^2 – 1, contradicting our assumption that it is not a factor of x^2 – 1. Therefore, our initial assumption is wrong, and 8 must be a factor of x^2 – 1 if x is an odd integer.
4. To prove this statement by indirect proof, assume that x is an even integer but xy is an odd number. Since x is an even integer, it can be written as x = 2k, where k is an integer. This can be substituted into xy = (2k)y to create xy = 2ky. Since both k and y are integers, 2ky is an even number. This means that xy is an even number, contradicting our assumption that it is an odd number. Therefore, our initial assumption is wrong, and xy must be an even number if x is an even integer.

assuming that the curve is banked and the road is frictionless, determine the bank angle with respect to the horizontal.
The bank angle for a frictionless curved road can be calculated using the equations of motion.
The equation of motion for a particle in a curved road is given by F = mgsin(θ) where F is the centripetal force, m is the mass of the particle, g is the acceleration due to gravity and θ is the bank angle. Thus, the bank angle can be calculated by rearranging the equation to θ = arcsin(F/mg). For example, if the mass of the particle is 5kg, the centripetal force is 30N and the acceleration due to gravity is 9.8ms-2, then the bank angle would be θ = arcsin(30/5x9.8) = 20.7°.

To test the hypotheses h0: p1 = p2 and Ha: p1 ≠ p2, we can use a two-sample proportion test. This test compares the proportion of success (no longer being late to school) in the control group (p1) to the proportion of success in the treatment group (p2) to determine if there is a statistically significant difference between the two proportions.
Here are the steps to perform the test:
State the hypotheses:
h0: p1 = p2 (the proportion of success in the control group is equal to the proportion of success in the treatment group)
Ha: p1 ≠ p2 (the proportion of success in the control group is not equal to the proportion of success in the treatment group)
Select a significance level (alpha): usually, it is set as 0.05
Calculate the test statistic:
p = (p1n1 + p2n2) / (n1 + n2)
z = (p1 - p2) / sqrt(p*(1-p)*((1/n1)+(1/n2)))
Find the p-value:
Using the z-score, look up the probability in a standard normal table.
Make a decision:
Compare the p-value to the significance level. If the p-value is less than or equal to the significance level, then reject the null hypothesis. If the p-value is greater than the significance level, then fail to reject the null hypothesis.
Conclusion:
Interpret the results in terms of the research question. If the null hypothesis is rejected, then the results suggest that there is a statistically significant difference in the proportion of success between the control group and the treatment group

ana lopez borrow $5000 for 75 days at 8% exact interest find how much interest she must pay on the loan and how much will be die at maturity?
To find the interest Ana must pay on the loan, we can use the formula:
Interest = Principal x Interest Rate x Time (in days) / 365
What's the math rate?
A rate is a unique ratio where the two words are expressed in several units. For instance, the price is 69 for 12 ounces if a 12-ounce can of maize costs 69. This is not a proportion of two comparable units, like shirts. Cents and ounces are the two dissimilar units in this ratio.
In this case:
Interest = $5000 x 8% x 75 / 365 = $200
So, Ana must pay $200 in interest on the loan.
To find the total amount due at maturity, we add the interest to the principal:
Total Due = Principal + Interest = $5000 + $200 = $5200
So, Ana will need to pay $5200 at maturity.

Step-by-step explanation:
The area of a circle is π · r^2. simply plug in the radius of 5.5 into "r" and then you square it. Squaring it would result in 30.25. Finally, you multiply it with π. Since you are multiplying two unlike terms, you put the coefficient first and then the variable. The measurements are in millimeters squared so you would have to add them after 30.25π otherwise it would be wrong.

HELP ASAP! FIND LINEAR EQUATION PARALLEL TO Y = -3/4X + 1 THROUGH POINTS (8,-6)
The equation of the line parallel to y = (-3/4)x + 1 and passing through (8, 6) is y = (-3/4)x
What is an equation?An equation is an expression showing the relationship between numbers and variables.
The slope intercept form of a straight line is:
y = mx + b
Where m is the slope and b is the y intercept.
Two lines are parallel if they have the same slope.
Given the line y = (-3/4)x + 1, the slope is -3/4. The line parallel to y = (-3/4)x + 1 would have same slope of -3/4.
The parallel line passes through (8, -6), hence:
y - y₁ = m(x - x₁)
y - (-6) = (-3/4)(x - 8)
y + 6 = (-3/4)x + 6
y = (-3/4)x
The equation of the line is y = (-3/4)x

Directions: Solve for x. Round to the nearest tenth.
Answer:
x = 73
Step-by-step explanation:
Since it's asking for the angle it's going to be inverse (sin-1,cos-1,tan-1)
It only gives you the opposite side and the hypotenuse
You can find the opposite side by going opposite from the missing angle like basically the side that is not being touched by x (The 4) This is the opposite angle
The hypotenuse is always going to be the long angle that is on the opposite side of the right angle (The 6) This is the hypotenuse
The adjacent side is the side not opposite to the x
Remember the acronym SOH CAH TOA
sin-opposite/hypotenuse
cos-adjacent/hypotenuse
tan-opposite/adjacent
The opposite and hypotenuse are the only sides that gave a number so it is sin and is inverse
[tex]sin^{-1} (\frac{4}{6} ) = .729[/tex]

: find the point on a directed line segment between two given points that partitions the segment in a given ratio.
The point that partitions the line in the ratio of 1:3 is (1.333, 3.333).
Given two points P1(x1,y1) and P2(x2,y2), the point that partitions the directed line between these two points in a given ratio r can be calculated using the following formula:
P(x,y) = (x1 + r(x2-x1), y1 + r(y2-y1))
For example, if we have P1(1,2) and P2(4,6) and we want to partition the line in a ratio of 1:3, the point P(x,y) can be calculated as follows:
P(x,y) = (1 + 1/3(4-1), 2 + 1/3(6-2)) = (1.333,3.333)
Therefore, the point that partitions the line in the ratio of 1:3 is (1.333, 3.333).
