100 fewer people went to the pool than in the first week. In the third week,
130 more people went to the pool than in the second week. In the fourth week,
234 fewer people went to the pool than in the third week. What is the percent decrease in the number of people who went to the pool over these four weeks?
20% is the percent decrease in the number of people who went to the pool over these four weeks
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given,
In the first week of July, a record 1,020 people went to the local swimming pool.
In the second week,100 fewer people went to the pool than in the first week
1020-100=920
In the third week,130 more people went to the pool than in the second week.
920+130=1050
In the fourth week, 234 fewer people went to the pool than in the third week.
1050-234=816
Now we need to find the percent decrease in the number of people who went to the pool over these four weeks
1020-816=204
204/1020=0.2×100=20
Hence, 20% is the percent decrease in the number of people who went to the pool over these four weeks

what happens to the mean for a trait in a population during directional selection what is being selected for?
When a population is subjected to directional selection over time, the traits that are selected for will remain stable while the traits that are selected against will disappear.
Evolution is the study of how populations change over time. Most traits have multiple genes controlling their structure, function, appearance, and other characteristics. Single genes only very infrequently control a trait.
As a result, most traits have a tendency to be continuous in nature and to have a wide range of values. One side of these values will be picked against during directional selection, while the other side will be selected in favor of. Look at the illustration of a lemur's fur color below.

From the given statements about the linear graph, the correct ones are statements 1, 2 and 3 while the incorrect one is statement 4
How to interpret Linear Graphs?The slope of a linear graph is simply the change in the y-values divided change in the corresponding x-values.
Now, from the graph, if we take two coordinates, we can easily say that;
Slope = (18 - 16)/(0 - 100)
Slope = -2/10 = -1/5
Statement 1; From the graph, the y-intercept is $18. This means that this is the cost of the book as that is where the cost starts decreasing for each weed she pulls. Thus, it is true.
Statement 2; The slope as we saw earlier was -1/5. Thus, it means that her grandma pays $1 for every 5 weed she pulls.
Statement 3; The x-intercept is 90 and it means after 90 weeds pulled, she no longer has to use her own money at all for the book. This is correct.
Statement 4; This is wrong because she needs to pull at least 90 weeds for her not to use her money.

On Monday you run on treadmill for one half an hour at X mph on Tuesday you walk the same distance on the treadmill at 2 mph slower and it takes you three fourths an hour how many miles did you run on the treadmill on Monday
The number of miles that you ran on the treadmill on Monday will be 3 miles.
What is speed?Speed is defined as the length traveled by a particle or entity in an hour. It is a scale parameter. It is the ratio of length to duration.
We know that the speed formula
Speed = Distance/Time
On Monday you run on the treadmill for thirty minutes at x mph and on Tuesday you walk a similar distance on the treadmill at 2 mph increasingly slow takes you three-fourths 60 minutes.
Then the distance is the same in both cases. Then we have
x × (1/2) = (x - 2) × (3/4)
Simplify the equation, then we have
x × (1/2) = (x - 2) × (3/4)
4x = 6(x - 2)
4x = 6x - 12
2x = 12
x = 6 miles per hour
The number of miles is given as,
D = 6 × 1/2
D = 3 miles

What is meant by an angle?An angle is a figure in Euclidean geometry made up of two rays that share a terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are located in the plane where the rays are located. The meeting of two planes can also create an angle. These are referred to as dihedral angles. The angle formed by the rays lying perpendicular to the two intersecting curves at their point of intersection can likewise be used to establish an angle between two intersecting curves.
Given,
In ΔLMN,
m ∠L=28°
As we know that,
Angle sum in a triangle=180°
m ∠L+ m ∠M+ m ∠N=180°
From the figure,
m ∠M= m ∠N
So, m ∠L+ m ∠M+ m ∠M=180°
28°+ 2 m ∠M=180°
2 m ∠M=180°-28°
2 m ∠M=152°
m ∠M=76°

The difference between the roots of the quadratic equation x^2+x+c=0 is 6. Find c.
Answer:
c=-35/4
Step-by-step explanation:
For this, we would use Vieta's theorem, which states the roots of the equation added together would equal -b/a, x₁ + x₂ = -b/a
Lets create a system with this:
x₁ - x₂ = 6 (This is given from the problem)
x₁ + x₂ = -b/a or -1/1, plugging in the values from your equation
next, we would add these systems together
x₁ + x₂ + (x₁ - x₂) = 6 + (-1)
x₁ + x₁ = 5
2x₁ = 5
x₁ = 2.5
If we plug x₁ back in, we get:
2.5 - x₂ = 6
-x₂ = 3.5
x₂ = -3.5
Now that we have the roots, we can use Vieta's theorem again to say
x₁ * x₂ = c/a
Plugging this in, we get:
2.5 * -3.5 = c/a
Lets change things to fractions to make things easier
5/2 * -7/2 = c/a
Plugging in a, we get
-35/4 = c/1
-35 = 4c
c = -35/4

Given recursion function in options we have calculated values of f(1),f(2),f(3),f(4),f(5).
Find f(1), f(2), f(3), f(4), f(5) if f(0) = 3.
First recursive Function is given as
a) f(n+1) = -2*f(n)
f(1) = -2*f(0) = -2*3 = -6
f(2) = -2*f(1) = -2*(-6) = 12
f(3) = -2*f(2) = -2*12 = -24
f(4) = -2*f(1) = -2*(-24) = 48
f(5) = -2*f(4) = -2*(48) = -96
Second recursive Function is given as
b) f(n+1) = 3*f(n)+7
f(1) = 3*f(0)+7 = 3*3+7 = 16
f(2) = 3*f(1)+7 = 3*16+7= 55
f(3) = 3*f(2)+7 = 3*55+7 = 172
f(4) = 3*f(3)+7 = 3*172+7 = 523
f(5) = 3*f(4)+7 = 3*523+7 = 1576
Third recursive Function is given as
c) f(n+1) = [tex]f(n)^2-2*f(n)-2[/tex]
f(1) = f(0)*f(0)-2*f(0)-2 =3*3 - 2*3 - 2 = 1
f(2) = f(1)*f(1) - 2*f(1) - 2 = 1*1 - 2*1 - 2 = -3
f(3) = f(2)*f(2) -2*f(2)- 2 =-3*(-3) - 2*(-3) - 2 = 13
f(4) = f(3)*f(3) -2*f(3)- 2 = 13*13 - 2*13 - 2 = 141
f(5) = f(4)*f(4) -2*f(4)-2 = 141*141 - 2*141 - 2 = 19597
Fourth recursive Function is given as
d) f(n+1) = [tex]3^(f(n)/3)[/tex]
f(1) = 3^((f(0)/3) = 3^1 = 3
f(2) = 3^((f(1)/3) = 3^1 = 3
f(3) = 3^((f(2)/3) = 3^1 = 3

solve with quadratic formula
m = 5 and m = -9/5 are the roots of the equation.
Factoring 4m²-11m-45
The first term is, 4m² its coefficient is 4 .
The middle term is, -11m its coefficient is -11 .
The last term, "the constant", is -45
Step-1 : Multiply the coefficient of the first term by the constant 4 • -45 = -180
Step-2 : Find two factors of -180 whose sum equals the coefficient of the middle term, which is -11 .
-180 + 1 = -179
-90 + 2 = -88
-60 + 3 = -57
-45 + 4 = -41
-36 + 5 = -31
-30 + 6 = -24
-20 + 9 = -11 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -20 and 9
4m² - 20m + 9m - 45
Step-4 : Add up the first 2 terms, pulling out like factors :
4m • (m-5)
Add up the last 2 terms, pulling out common factors :
9 • (m-5)
Step-5 : Add up the four terms of step 4 :
(4m+9) • (m-5)
Which is the desired factorization

b) Find the slope of the line segment.
c) Write the equation of the line that contains the two points.
Answer:
a) 5
b) -4/3
c) y = -4/3x - 11/3
Step-by-step explanation:
The length of the segment means the length in between two points. Use 2 dimensional distance formula.
[tex]d = \sqrt{(x_{2}-x_{1})^2 + (y_{2}-y_{1})^2 }[/tex]
Plug in your points.
x value is the first point in the set, the horizontal measure in units.
y value is the second point in the set, the vertical measure in units.
x values of 2 points: -2, -5
y values of 2 points: -1, 3
[tex]d = \sqrt{(-5--2)^2 + (3--1)^2 }[/tex]
A negative value subtracted by another negative value is the first negative value plus the inverse of the second negative value.
For example,
-5 - -6 = -5 + 6 = 1
Simplify.
[tex]d = \sqrt{(-3)^2 + (4)^2 }[/tex]
[tex]d = \sqrt{9 + 16}[/tex]
[tex]d = \sqrt{25}[/tex]
5
Square root of 25 is 5 because 5^2, which is 5 x 5 is 25.
The slope is how much the y-value changes when the x-value increases by 1.
To calculate this, plug your points into the slope formula.
[tex]Slope = \frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\frac{3--1}{-5--2}[/tex]
[tex]\frac{4}{-3}[/tex]
-4/3
I'm going to assume that the problem is asking you to write it in the form of y=mx+b, or slope-intercept form, a way of easily graphing a line. If it is asking you to express it in another way like Standard or Point-Slope Form, comment and I'll change it.
y = mx+b
m = slope
b = y-intercept, or the y-value of when the x-value is 0 on a line
y and x stays as variables if you want to graph it and for generally answering problems.
So, if x = 0, we can plug it into what we currently know.
We know the points: (-2,-1) or (-5,3)
Plug in either set of points into the slope-intercept equation.
I'll use -2,-1 but you can use either.
-1 = (-4/3) (-2) + b
Because we're solving for when x is 0, replace -2 for 0.
-1 = 8/3 + b
Subtract 8/3 on both sides.
-1 - 8/3 = 8/3 - 8/3 + b
-1 - 8/3 = b
b = -11/3
Now, the equation is:
y = -4/3x - 11/3
This is the beauty of the forms of linear equations. You can plug in any points to solve for the full set of points. You can convert any form of the linear equation to another form.

We can determine if two triangles are congruent without evaluating all of their sides and angles. The phrase "congruent" refers to having exactly the same form and dimension. Even if we flip, turn, or rotate the forms, the shape and size should remain the same. In terms of shape and size, the adjective "congruent" implies "absolutely equal." The forms remain equal even when we spin, flip, or rotate them. Draw two circles with the same radius, then cut them out and stack them on top of each other.

The 10-sided die has the outcomes {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} so 10 outcomes.
The outcomes that are greater than 3 are {4, 5, 6, 7, 8, 9, 10} so there are 7 outcomes, then the probability is:
P = 7/10 = 0.7

Elian is placing a rectangle in the coordinate plane. He knows that the shorter side of the rectangle is half the length of the longer side. He places the longer side on the x-axis. What coordinates should he assign to the top-left vertex of the rectangle? enter your answer in the boxes. ( , ).
Since the rectangle's shorter side is half as long as its longer side, its top left vertex is (0,a).
What is coordinate?A pair of numbers that use the horizontal and vertical separations from the two reference axes to define a point's location on a coordinate plane. typically expressed by the x-value and y-value pair (x,y). You do the reverse to determine a point's coordinates in a coordinate system. Start at the point, then move up or down a vertical line until you reach the x-axis. Your x-coordinate is shown there. To find the y-coordinate, repeat the previous step while adhering to a horizontal line.
Here,
Let x be the length and y be the width,
y=x/2
x=2a
y=a
The top left vertex=(0,a)
The top left vertex is (0,a) as shorter side of the rectangle is half the length of the longer side.

In this triangle, what is the value of x?
The value of x in the triangle is 26.1°
What is a triangle?A triangle is a three-sided polygon that consists of three edges and three vertices. The most important property of a triangle is that the sum of the internal angles of a triangle is equal to 180 degrees. This property is called angle sum property of triangle.
Types of Triangles
Acute triangle - all three angles are less than 90°
Right triangle - one angle is 90°
Obtuse triangle - one angle is greater than 90°
Equilateral triangle - all three sides are the same length
Isosceles triangle - two sides are the same length
Scalene triangle - all three sides are different lengths
Since the triangle is right-angled
tan x = opposite/adjacent
tan x = 26/53
tan x = 0.4905
x = arc(tan) 0.4905
x = 26.1°
In conclusion x = 26.1°

what is the solution to the problem expressed to the correct number of significant figures? 2.13 1
The solution to the problem expressed to the correct number of significant figures is, 2.13 + 1 = 3
Given that,
The solution to the problem expressed to the correct number of significant figures,
2.13 + 1 = ?
Unit is a quantity of constant magnitude which is used to measure the magnitudes of other quantities of the same manner.
Unit can be defined as the rightmost position in a number or the one's place. Here, 3 is the unit's number in the number 6713. A unit may also mean the standard units used for measurement.
You must round your answer to the same "place" when adding values as the measurement with the last significant figure that is farthest to the left.
= 2.13
= +1
= 3.13
The “1” has its last significant figure furthest to the left, so you round off the number to the “units" place. That's the last column that the measurements share.
3.13 → 3 (rounded to the "units" place)
Therefore,
The solution to the problem expressed to the correct number of significant figures is, 2.13 + 1 = 3
