The new dimension of the rectangle can be found as follows;

The sides of a square are equal.

Therefore,

let the side of the square = x

Hence,

length = x + 3

width = x + 1

area of rectangle = lw

Answer:

y = -13x + 4

Step-by-step explanation:

You want to put it in the form y = mx + b where m is the slope and b is the y-intercept (For example, in the equation y = 2x + 3 the slope is 2 and the y-intercept is 3)

Since the slope is -13, m = -13.

Since the y-intercept is 4, b = 4.

This means the equation is y = -13x + 4

The difference in percentage of youngest and oldest age groups is 15.4%

Start by calculating the total number of people, as follows

People = 102 + 36 + 66 + 150 + 78 + 60 + 90 + 11 + 9

Evaluate

People = 602

The number of people in the age group 11 to 20 is:

Group = 36

So, the percentage is

Percentage = 36/602

Percentage = 6.0%

Hence, the percentage from 11 to 20 is 6.0%

The number of people in the age group 31 to 40 is:

Group = 150

So, the percentage is

Percentage = 150/602

Percentage = 24.9%

Hence, the percentage from 31 to 40 is 24.9%

The number of people in the age group 71 to 80 is:

Group = 11

So, the percentage is

Percentage = 11/602

Percentage = 1.8%

Hence, the percentage from 71 to 80 is 1.8%

This is the percentage of age group 81 to 90

And, the percentage is

Percentage = 9/602

Percentage = 1.5%

Hence, the lowest percentage on the chart is 5%

The number of people in the age group 31 to 70 is:

Group = 60 + 90 = 15-

So, the percentage is

Percentage = 150/602

Percentage = 24.9%

Hence, the percentage from 51 to 60 and 61 - 70 combined is 24.9%

The youngest is 0 to 10 and the oldest is 81 to 90.

The number of people in these age groups are:

Youngest = 102

Oldest = 9

The difference is

Difference = 102 - 9

Difference = 93

So, the percentage is

Percentage = 93/602

Percentage = 15.4%

Hence, the difference in percentage of youngest and oldest is 15.4%

The point where he  buried his treasure is (6.28,9.84)

First of all, we are going to find the equation of the line which describes the first path crossed by the horseman.  In order to find it we have to take into account that the vector V  provides us with the direction of this path. We can associate the direction with the slope of the line. The slope is defined by the ratio of vertical changes to horizontal changes between two points.  

According to the V=6i+5j, we can determine that:

Vertical change (y)= 5

Horizontal change (x)=6

Slope=\frac{5}{6}

Now, using the point-slope form:

y-y₁=m(x-x₁)

The chosen point is the point where the horseman began riding (-2,5). Therefore:

m=5/6

y1=5

x1=-2

y-5=5/6(x+2)

y=5x/6-10/3

Since the horseman at some point turned at a right angle towards village B  and he unchanged his direction until arrived in village B, the second path must be described by a line perpendicular to the first path.  

We should know that two lines are perpendicular if and only if their slopes are negative reciprocals This means m1*m2=-1

m₁=5/6

m₂=-1/m₁=-6/5

In order to find the equation of the second path, we will use again the point-slope form.

The chosen point is the point where is located Village B (2,11)

y-11=-6/5(x-2)

y=-6x/5+13.4

The coordinates of the point where the horseman buried a jar full of silver coins correspond to the intersection of path 1 and path 2. Therefore we are going to equal the two equations of each path.

5x/6-10/3=-6x/5+13.4

Solving this equality for x

X=6.28

Replacing this value in any of the equations of the paths

Y=9.84.

Finally, the point where he buried his treasure is (6.28,9.84).

The probability that a friend will randomly choose an integer between 1 and 10, inclusive, that is more than 8 or odd is 7/10 or 0.7.

To see why, we can count the number of integers between 1 and 10 that are more than 8 or odd. The integers more than 8 are 9 and 10, and the odd integers are 1, 3, 5, 7, and 9.

The set of integers that satisfy either condition is {1, 3, 5, 7, 9, 10}, which has a total of 6 elements. Since there are 10 possible integers, the probability of choosing an integer that satisfies either condition is 6/10 or 0.6.

However, we must also include the probability of choosing 9 or 10, which individually have a probability of 1/10. Thus, the total probability is 0.6 + 0.1 + 0.1 = 0.7.

The sample size is enough to estimate the population parameters and the estimate is not incorrect even if the daily returns are not normally distributed.

Given, a store owner wants to estimate the average daily profit of that store. That person takes a sample of n=60 days to estimate. Let us check if the given sample size is enough to draw conclusions about the population or not.

Central Limit Theorem: The central limit theorem (CLT) states that the sampling distribution of the sample mean is normally distributed if the sample size is large enough (n > 30).

The sampling distribution of the sample mean is a normal distribution, regardless of the population's shape and standard deviation if the sample size is large enough. For a sample size n>30, the mean of the sample means is equal to the population mean, and the standard error of the sample means is equal to the population standard deviation divided by the square root of the sample size.

The sample size in this case is n = 60 which is greater than 30. Therefore, the central limit theorem holds, and the sample mean is normally distributed with a mean equal to the population mean and a standard error equal to the population standard deviation divided by the square root of the sample size.

The altitude of an equilateral triangle is basically the height of the triangle. We can find this using trigonometry, even though I'm sure there's a beautiful little formula that can find this.

If you cut an equilateral triangle in half, you get two special 30-60-90 triangles. The base of each triangle is 3.5 cm in length, and the height (not the hypotenuse!) is equal to:

\(base*\sqrt{3}\)

So basically we have 3.5(sqrt(3)), or our altitude! Wow, how easy!

\(3.5(\sqrt{3})=6.06\)

Hope this helps!

The number of children who like both pistachio and chocolate ice cream is 73.

Here we have to find at least one kind of ice cream liked by the children.

It is given that the total number of children is 395. The number of children who don't like any ice cream is 170.

So we get the number of students who like one or both the ice cream is 395 - 170 = 225.

Here it is provided that 123 children like pistachio ice cream and 175 children like chocolate ice cream.

So the total number of children who like pistachio and chocolate ice cream is 175+ 123 = 298. Which cannot be greater than 225.

So the number of children who like both ice creams is 298 - 225 = 73.

Step-by-step explanation:

The speed of an airplane is 208 miles per hour.

The speed of wind is 48 miles per hour.  

The distance covered by airplane against the wind = D = 640 miles

The time taken to cover D distance = T = 2.5 hours

Again

The distance covered by airplane with the wind = d = 460 miles

The time taken to cover d distance = t = 2 hours

Let The speed of the airplane = x mile per hour

and the speed of wind = y miles per hour

we know that -

∵ Speed = distance/ time

speed of airplane while moving against the wind

x - y =   D/T

Or, x - y =   640/4

Or, x - y = 160 mph        ........1

speed of airplane while moving with the wind

x + y =   d/t

Or, x + y = 640/ 2.5

Or, x + y = 256 mph        ........2

Now, Solving eq 1 and eq 2, we get,

(x - y) + (x + y) = 160mph + 256mph

Or, (x + x) + ( - y + y) = 416 mph

Or, 2 x + 0 = 416 mph

∴  x = 416/2

i,e x = 208 mph

So, The speed of airplane = x = 208 miles per hour

Now, substitute the value x = 208 in equation 1, we get,

∵  x - y = 160mph

So, 208 mph - y = 160 mph

Or, y = 208 mph - 160 mph

i.e y = 48 mph

So, The speed of wind = y = 48 miles per hour

Hence, The speed of an airplane is 208 miles per hour and the speed of wind is 48 miles per hour.

The percent greater means the value increase according to that percent.

In the given question, we have to explain what does percent greater mean.

As we know that;

A figure or ratio stated as a fraction of 100 is called a percentage. It is frequently indicated by the percent sign, "%."

If percentage is greater that means we add that maximum percentage to 100 because every item is 100% to himself.

Then the number obtained after adding the greater percent to the 100, is the main percentage of the given value.

Then we divide the total percent by 100, then we get total maximum value.

Let the something gets x% stronger, you must also factor in its original 100% strength, which is expressed as follows:

x% + 100% = (x+100)%

Additionally, keep in mind that "percent" refers to anything relative to 100, therefore we can rephrase the percentage as a number:

(x+100)% = (x+100)/100 = 0.01x+1

Therefore, something that is x% stronger is (0.01x+1) times as strong.
