What is permutations and combinations?By choosing some items from a set and creating subsets, permutation and combination are two approaches to represent a group of objects. It outlines the numerous configurations for a particular set of data. Permutations are the selection of data or objects from a set, whereas combinations are the order in which they are represented. Both ideas are critical to mathematics.Here is a detailed explanation of permutation and combination, along with their distinctions.acc to our question-

Step-by-step explanation:
the picture is very blurry.
I understand we need the y-intercept in every case and then move the pictures into the empty frames based on sorting these numbers from lowest to highest.
the y-intercept is the point, where a function/curve intersects the y-axis.
in other words, it is the y-value of the point, where x = 0.
so,
1. 0
2. -6
3. looks like -2 (again, very blurry)
4. looks like +2

The surface area of a square pyramid is 96 square feet. The height is two-thirds of the length of the base edge.
What is the length of the base edge?
The length of the base edge of the pyramid is …
feet.
The length of the base edge of the given square pyramid is 3.67 feet.
What is the Surface Area?
The sum of all an item's faces makes up the surface area of a three-dimensional object. When wrapping, painting, and finally creating things to get the finest possible design, we apply the idea of surface areas of various items in real life.
What is a Square Pyramid?
In geometry, a pyramid with a square base and four lateral sides is referred to as a square pyramid.A polyhedron with a base and three or more triangle faces that meet above the base is called a pyramid (the apex). A pentahedron is a three-dimensional structure with a total of five faces, such as a square pyramid. The Great Pyramid of Giza is one of the most well-known examples of a pyramid like this in real life.Steps to Calculate the Base Edge Length of Square Pyramid
The formula for surface area of square pyramid is given by, [tex]SA=a^{2} +2a\sqrt{\frac{a^{2} }{4}+h^{2} }[/tex], -----(1)
where [tex]a[/tex] is the length of the base edge and [tex]h[/tex] is the square pyramid height.
In the question, it is given that the surface area of the square pyramid is 96 square feet.
The height of the square pyramid is two-thirds of the base edge length.
[tex]\implies h=\frac{2a}{3}[/tex] ------(2)
Now substituting the given values in (1), we get
[tex]96=a^{2} +2a\sqrt{\frac{a^{2} }{4}+(\frac{2a}{3} )^{2} }\\\implies 96=a^{2} +2a\sqrt{\frac{a^{2} }{4}+\frac{4a^{2} }{9} }[/tex]
Simplifying, we get
[tex]96=a^{2} +2a\times 0.834a^{2} \\\implies 96=a^{2} +1.668a^{3} \\\implies 1.668a^{3}+a^{2} -96=0[/tex]
Finally, we get the value of [tex]a=3.67[/tex] feet.
Therefore, the base edge length of the given square pyramid is 3.67 feet.

Grace runs a website that has gotten quite popular. However, its popularity seems to have
peaked, and the site is now getting 7% fewer hits each week. If Grace's site got 38,800 hits
this week, how many weekly hits can she expect it to get 7 weeks from.
Answer:
23346
Step-by-step explanation:
You want to know the number of hits on Grace's website 7 weeks from now if she gets 38,800 now and the number decreases 7% per week.
Growth factorThe growth factor per week is ...
growth factor = 1 + growth rate
The growth rate of hits is -7% per week, so this is ...
growth factor = 1 -7% = 0.93
Exponential functionThe exponential function describing the number of hits can be written ...
hits = (initial value)(growth factor)^weeks
hits = 38,800(0.93^weeks)
Then in 7 weeks, the number of hits is expected to be ...
hits = 38,800(0.93^7) ≈ 23,346
Grace can expect to get about 23,346 hits in 7 weeks.

There are 20 blue sweets in the jar.
The probability that the sweet Hannah takes will be red is twice the probability that the
sweet will be orange.
(a) Work out the number of red sweets in the jar.
the mom
the number of Red sweets=14
Let the probability of getting a red sweet be = P(R)
Let the probability of getting a Blue sweet be = P(B)
Let the probability of getting an orange sweet be = P(O)
Let the probability of getting a yellow sweet be = P(Y)
Let the number of Red sweets be represented as = n(R)
Let the number of Yellow sweets be represented as = n(Y)
Let the number of Orange sweets be represented as = n(O)
Let the number of Blue sweets be represented as = n(B)
Let the total number of sweets in the jar be represented as = n(T)
P(B) = 0.5
P(E) = 0.2
P(R) = 2 x P(O)
The formula of probability =
Number of the Sweets of a color/Total number of sweets in the jar
then,
P(B)=n(B)/ n(T)
P(B)=0.5 (Given in question)
n(B)=20 (Given in question)
So,
0.5 = 20/n(T)
5/10 = 20/n(T)
5/10 x 1/20 = 1/n(T)
cross multiplying
n(T)=10/5 x 20
dividing 10 by 5 =2
n(T) = 2 x 20
n(T) = 40
P(Y)=0.2 (Given in question)
Applying the formula of probability
P(Y) = n(Y)/n(T)
putting values
0.2=n(Y)/40
2/10=n(Y)/40
2/10 x 40 =n(Y)
Dividing 40 by 10 = 4
n(Y)= 2 x 4
n(Y)= 8
P(R)=2P(O)
Applying the formula of probability
n(R)/n(T)=2n(O)/n(T)
Cancelling out n(T) with n(T)
So,
n(R)=2 x n(O) -(i)
n(T) = n(O)+n(R)+n(B)+n(Y)
putting values
40=n(O)+n(R)+20+8
40=n(O)+n(R)+28
40-18=n(O)+n(R)
From -(i)
22=2n(O)+n(O)
22=3n(O)
n(O)=22/3
Since,
n(R)=2xn(O)
n(R)=2x22/3
n(R)=44/3
n(R)=14.6
the number of Red sweets=14.6

The length and width of a rectangle that maximises the enclosed area are 800 yards. The maximum area is 640,000 square yards.
In the given question we have to find the maximum area of the rectangular area.
Liana has 3200 yards of fencing to enclose a rectangle.
As we know that the perimeter of rectangle
P= 2(l+b)
Let length of the rectangle is x yards and width is y yards.
So the equation should be
2(x+y) = 3200
Divide by 2 on both side we get
x+y = 1600................(1)
From the area of rectangle is
A = xy
From the equation the value of y is 1600-x.
Now putting the value of y
A = x(1600-x)
A = 1600x-x^2
On differentiating
dA/dx = 1600-2x
Putting dA/dx=0
1600-2x=0
Subtract 1600 on both side we get
-2x= -1600
Divide by -2 on both side we get
x = 800 yards
Now putting the value of x in the y=1600-x
y=1600-800
y=800 yards
So the maximum area is
A= 800*800
A= 640,000 square yards
Hence, the length and width of a rectangle that maximises the enclosed area are 800 yards. 640,000 square yards is the maximum area.

S=59.951
Multiply by 12 to get inches

2x - 3x - 1 = 3
So , after the first step the equation should be 2x - 3x - 1 = 3
we see that the Distributive property of multiplication , was not used properly as the negative sign was not distributed to both the terms .

0. 57 miles2 converted into feet2
0.57 mi² = 15,890,688 ft² after converting square miles in square foot.
Define the meaning of unit conversion?A unit conversion is the expression of the same feature in an another unit of measurement. Time, for example, can be stated in minutes rather than hours, and distance can be translated from miles into kilometers, feet, or indeed any length measurement. Measurements are frequently stated in one set of units, including feet, but require different units, such like chains. A conversion factor seems to be a numerical equation that allows for the equal exchange of feet and chains.The given conversion in question is-
0.57 mi² = __ ft²
We know that
1 mi² = 27,878,400 ft²
Then, multiply both sides by 0.57
1 x 0.57 mi² = 27,878,400 x 0.57 ft²
0.57 mi² = 15,890,688 ft²
Thus, the conversion of 0.57 mi² = 15,890,688 ft².
