The sampling computed simply illustrates that the population mean will be 20.
How to solve the samplingIt should be noted that the population mean will be calculated thus:
= (6 + 24 + 18 + 20 + 32)/5
= 100/5
= 20
It can be deduced that the sample mean is an unbiased estimator of the population mean.
Lastly, when there's an increase in the sample size, the variability of the sampling distribution change. This is because there's a reduction.

Find the surface area of a square pyramid with side length 3 m and slant height 5 m.
Information provided with us:
Side length ( a ) = 3mSlant height ( l ) = 5mⳘ⳽ⲓⲛⳋ ⳨ⲟⲅⲙⳙⳑɑ :
Surface area of square pyramid is given by the sum of areas of all its 4 triangular sides and the square base area. If a is the base side length and l is the slant height , then the surface area of square pyramid is:
ㅤㅤㅤㅤㅤ➙ a² + 2al
Ⲧⲏⲉⲅⲉ⳨ⲟⲅⲉ:
ㅤㅤㅤ➙ A = a² + 2al
ㅤㅤㅤ➙ A = ( 3 ) ² + 2 × 3 × 5
ㅤㅤㅤ➙ A = 9 + 30
ㅤㅤㅤ➙ A = 39m²
~Hence, the surface area of given square pyramid is 39 m².
Answer:
39 m²
Step-by-step explanation:
surface area of square based pyramid = [tex]a^2+2al[/tex]
(where [tex]a[/tex] is the side length of the base and [tex]l[/tex] is the slant height)
Given:

If 4 lattes cost 15 dollars how much would 6 caffe lattes cost?
PLEASE HELP
Answer:
The lattes would cost about 22.50
Step-by-step explanation:
In order to figure out how much 6 lattes cost we need to know how much 1 is.
So you take 15 divided by 4 which gets you 3.75
Then you take 3.75 and times it by 6. Getting you the answer of 22.50
Answer:
$22.5
Step-by-step explanation:
It would be 22.5$ because if lattes cost 15$ then we need to find the cost of 1.
To do this by we divide 15 by 4.
3.75
4{15}
-0
___
15
- 12
--------
3 so because there is 3 left of 4 is is .75 because it couldn't make it to 4
so since 1 latte cost 3.75$ we times 3.75 by 6 latte.
Here are 3.75 times numbers 1-6.
3.75 x 3=11.25
3.75 x 4=15
3.75 x 5=18.75
3.75 x 6=22.5 and there's your answer,you get 6 lattes for 22.5$ or 22$ and 50 cents.

Step-by-step explanation:
Create a linear equation for line AB and line CD
Find slope using slope formula [tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
then use point-slope form of linear equation [tex]y-y_1=m(x-x_1)[/tex]
(where m is the slope and [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are two points on the line)
Line AB
[tex]m=\dfrac{-16+1}{-8+20}=-\dfrac54[/tex]
[tex]\implies y+1=-\dfrac54(x+20)\\\\\implies y=-\dfrac54x-26[/tex]
Line CD
[tex]m=\dfrac{0+11}{-19+9}=-\dfrac{11}{10}[/tex]
[tex]\implies y+11=-\dfrac{11}{10}(x+9)\\\\\implies y=-\dfrac{11}{10}x-\dfrac{209}{10}[/tex]
To find the point of intersection, equate the equations and solve for x::
AB = CD
[tex]\implies -\dfrac54x-26=-\dfrac{11}{10}x-\dfrac{209}{10}[/tex]
[tex]\implies -\dfrac{3}{20}x=\dfrac{51}{10}[/tex]
[tex]\implies x=-34[/tex]
Substitute found value of x into one of the equations and solve for y:
[tex]y=-\dfrac54(-34)-26=\dfrac{33}{2}[/tex]
Therefore, point of intersection is [tex]\left(-34, \dfrac{33}{2}\right)[/tex]
Casey constructed this figure by using a compass and a straightedge to draw circle O and diameter PQ. She then used a compass to draw two arcs. She labeled the points where those arcs intersect the circle M and N, and she drew the chords that form the triangle.
If ΔMNP is equilateral, how did Casey draw the arcs that defined points M and N?
A.
She used a compass centered at P with a radius set equal to PQ.
B.
She used a compass centered at O with a radius set equal to PO.
C.
She used a compass centered at Q with a radius set equal to PO.
D.
She used a compass centered at P with a radius set equal to (PQ).
E.
She used a compass centered at Q with a radius set equal to PQ.
Answer:
D) she used a compass at P with a radius set equal to 3/4(PQ)
Step-by-step explanation:
Step 1
She used a compass at P with a radius set equal to 3/4PQ .
Step 2
Since if ∆MNP is equilateral triangle so, PM=PN=MN
Since O is center then PO=OQ
And let R is the mid point of MN.
So, R is also mid point of OQ.
Hence, she used a compass at P with a radius set equal to 3/4(PQ)

PLS ANSWER ASAP! Enter the equation of the line in the form y=mx Where m is slope
Answer:
Well technically its inf due to the arrow, there are no points showing where to start from and where to end
the way you do it it you just count the amount of units it goes up, in this case for every square its going up 5 units, once you get that number you put that on top of your fraction, then you go over on the x axis till you hit your line (x axis is going by 10 every time). This would be your number on the bottom of the fraction.

The picture represents a hippo pool surrounded by a park.
The two pentagons are similar with AB = 3 CD and the area
of the park is 2,700sq.m Find the area of the pool?
Given that the two pentagons are similar figures, the area of the pool = 675 sq. m..
What is the Area of Similar Figures?If two figures are similar to each other, then, the ratio of the square of their corresponding sides equals the ratio of their areas.
We are given that the pool and the park are similar to each other. The diagram given is missing, however, here's how to find the area of the pool:
If x is a side of the pool and y is the corresponding side length of the park, therefore:
area of pool/area of park = x²/y².
Plug in the values given, cross multiply and find the area of the pool.
For example, if 3 is a side of the pool = x
6 is corresponding side of the park = y
Area of park = 2,700 sq. m
Thus:
Area of pool/2,700 = 3²/6²
Area of pool/2,700 = 9/36
Area of pool = (9 × 2,700)/36
Area of pool = 675 sq. m.

Which statement best describes the rotation?
A. Clockwise 90-degree rotation
B. Clockwise 270-degree rotation
C. Counterclockwise 90-degree rotation
D .Counterclockwise 270-degree rotation
Answer:
B. Clockwise 270-degree rotation
Answer:
B) Clockwise 270-degree rotation
Step-by-step explanation:
Clockwise motion is in the same direction as a clock's hands: from the top to the right, then down and then to the left, and back up to the top. The opposite motion is counterclockwise.
From inspection of the diagram, we can see that the curved dotted line (which shows the direction of motion) is suggesting a clockwise motion.

Step-by-step explanation:
total animals = 160
⇒ 10% of animals = 160/10 = 16
⇒ 20% = 16 x 2 = 32
