On solving the provide outlier question, we can say that The difference between the upper and lower fourth makes up the fourth outlier (h) = 73.7 - 22.2 = 51.5

Outliers are data points that deviate from the distribution's typical pattern. a value that is "outside" of the record's typical range (either significantly lower or substantially greater). For instance, both 3 and 85 are "outliers" when the scores are 25, 29, 3, 32, 85, 33, 27, 28, etc. Move away. Look for values that are significantly larger or significantly smaller than all other values to identify outliers. Because it is significantly smaller range than all other values, Value 4 is an outlier. An observation that differs unusually from other values in a population sample taken at random is referred to as an outlier.

Here,

a) The data values should now be sorted from smallest to largest:

22.2 40.4 16.4 73.7 36.6 109.9

b) The sorted data set's median is its middle value. The median is the sixth data value in the sorted data set because there are 11 data values total:

m = 36.6

c) The median of the data values below the median, or at 25% of the data, is in the lower fourth.

The lower fourth is the third data value because there are 5 data values below the median.

d) The data value 6 + 3 = 9 represents the third quartile.

Answer:

the solution is u5/2

Answer:

91.1cm²

Step-by-step explanation:

since all of them are quarters of circles

area of figure 1 = (π(r.1)²)÷4 = (64π)÷4= 16π cm²

area of figure 2 = (π(r.2)²)÷4 = (25π)÷4= 6.25π cm²

area of figure 3 = (π(r.3)²)÷4 = (9π)÷4= 2.25π cm²

area of figure 4 = (π(r.4)²)÷4 = (4π)÷4= 4π cm²

area of figure 5 = (π(r.5)²)÷4 = (π)÷4 cm²

area of figure 6 = (π(r.6)²)÷4 = (π)÷4 cm²

the total area = 16π+6.25π+2.25π+4π+2(π÷4)=

28.5π+0.5π = 29π = 91.1cm²

So,

The skateboard cost $67.

The protective helmet cost $25.

To find the percent that the price of the skateboard was out of the total amount, add 67 and 25 and divide 67 by the result.

Step 1:

67 + 25 = 92

Step 2:

67/92 = 0.728 or 72.8%.

Answer: The half-life of a radioactive isotope is the time it takes for a quantity of the isotope to be reduced to half its initial mass.

If the initial mass is 185 grams, after the first half-life, the mass will be reduced to 185/2 = 92.5 grams

After the second half-life, the mass will be reduced to 92.5/2 = 46.25 grams

After the third half-life, the mass will be reduced to 46.25/2 = 23.125 grams

So, after three half-lives, there will be 23.125 grams of the isotope left.

It's important to note that the half-life of the isotope is a constant value and it doesn't depend on the initial mass.

Answer: $23,800

Step-by-step explanation:

It was worth $37,000 at first and now it's worth $1800.

So we have 37,000 - 1800 = $35,200 that left away.

And we know that 8 years passed away.

So we have 35,200/8 = $4400 each year.

We are looking for 3 years later.

So we have 440*8 = $13,200 that left after 3 years.

And lastly, it's worth 37,000 - 13200 = $23,800 3 years later.

If henry can  70 words in 5 minutes and that in 8 minutes he can type 112 words the rate of change is 14.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

Henry can type 70 words in 5 minutes and that in 8 minutes he can type 112 words.

Probability theory, a subfield of mathematics, gauges the likelihood of an occurrence or a claim being true. An event's probability is a number between 0 and 1, where approximately 0 indicates how unlikely the event is to occur and 1 indicates certainty. A probability is a numerical representation of the likelihood or likelihood that a particular event will occur. Alternative ways to express probabilities are as percentages from 0% to 100% or from 0 to 1. the percentage of occurrences in a complete set of equally likely possibilities that result in a certain occurrence compared to the total number of outcomes.

To find the number of females who are not enrolled in Composition I, we can look at the table and find the total number of females and subtract the number of females who are enrolled in Composition I.

The total number of females is found in the "Column Totals" row, in the second column, and is 251.

The number of females enrolled in Composition I is found in the "Males" row, in the second column, and is 46.

So the number of females who are not enrolled in Composition I is:

251 (total number of females) - 46 (females enrolled in Composition I) = 205

Therefore, the answer is 83.

Step-by-step explanation:

y = 37 + x

the 4th angle (bottom right) is

360 - 90 - 90 - 125 = 55°

because the sum of all angles in any quadrilateral is 360°.

now we can assume a right-angled triangle on the right side of the trapezium.

one leg is 15 cm (like the left side), the other leg is x cm. and the right side of the trapezium is the Hypotenuse.

the bottom right angle is 55°.

the upper angle is 125 - 90 = 35°.

we can use the law of sine to get x.

the law of sine is

a/sin(A) = b/(sin(B) = c/sin(C)

with a, b, c being the sides of the triangle opposite of the corresponding angles A, B, C.

so,

15/sin(55) = x/sin(35)

x = 15×sin(35)/sin(55) = 10.50311307... cm

y = 37 + 10.50311307... = 47.50311307... ≈

≈ 47.5 cm

To find the general solution of the given differential equation x dy/ dx − y = x^2 sin x, we must use a series of calculations.

First, we need to separate the variables, so y can be expressed as a function of x. To do this, we divide both sides of the equation by x, giving us the equation dy/dx = x sin x + y/x.

Next, we will need to use integration to find the general solution. To integrate, we need to find an antiderivative of the equation dy/dx = x sin x + y/x. To do this, we can use the formula ∫xdx = 1/2 x^2 + c. Using this formula, we can integrate both sides of the equation to get 1/2 x^2 + c = x sin x + ∫ y/x dx.

We can then solve for the antiderivative of y/x, which is ln|y| + c. Therefore, the general solution of the equation is 1/2 x^2 + ln|y| + c = x sin x + c.

Finally, we can solve for y in terms of x to get y = x^2 sin x + c'e^(1/2 x^2), where c' is the integration constant. This is the general solution of the given differential equation.

A stratified sample size is a method of sampling where the population is divided into homogeneous subsets and a sample is taken from each subset.

A stratified sample is a method of sampling where the population is divided into distinct subgroups, or strata, based on specific characteristics. This method of sampling ensures that each stratum is represented in the sample in the same proportion as it is in the population. This ensures that the sample is representative of the population. Stratified sampling is useful when the population is heterogeneous, which means that it is composed of subgroups that vary significantly in size or composition. By stratifying the population, it is possible to ensure that each subgroup is adequately represented in the sample. This method also helps to reduce sampling errors, which can occur if the sample is not representative of the population. Stratified sampling is a useful tool for researchers who want to accurately represent the population in their sample.

Therefore ,as a result, 42/5 is the value of the first term in the equation for the arithmetic mean.

The arithmetic average or means of the group is calculated as the sum of each value in a list divided by the total number of things in that list. The progression in mathematics is the same as this. The average of the integers 5, 7, and 9 is 4, as shown by the equation 5 + 7 + 9 being equal to 21, and 21 divided by 3 (there are actually three numbers) being equal to 7.

Here,

Given :

5 a + 10 d = 70 in the first five terms (1)

The first ten terms add up to 10 a + 45 d = 210. (2)

This means that in order to solve the system for a, multiply equation (1) by 2, then subtract it from equation (2):

=> 10a - 10a + 45d - 20d = 210-140

=> 25d = 70

=> d = 70/25

=> d = 14/5

A value then becomes:

5a + 10*14/5 = 70;

5a = 70-140/5;

5a = 350-140/5;

a = 42/5.
