A and C Step-by-step explanation:I would go for A and C options which best describes the use of data displays for the comparison of two data sets.Data Display is basically displaying of useful data which has been extracted from bundles of raw data or raw data points. That useful data can be used to compare two different datasets as well. So, in option A, It says that it quickly illustrate measures of centre. True, because it presents you quick display so that everyone seeing the data in form of charts or tables easily catch the information to be conveyed. And in option C, It says, they show trends in data that can be compared. Yes again true. Data displays show you trends of different things in one clear picture and it can be compared with other datasets through the use of data displays. Still stuck?

What is the value of the expression below?
4. 8 x 108
-x (2. 2 x 10-6)
1. 2 x 104
Answer:
I'm not sure I understand the formatting. I don't know what the x is supposed to be for the middle term (-x(2.2x10^6)), so I dropped the x for the calculation. I also assumed all terms are to be added. If these assumptioons are correct, the answer is:
4.58012 x 10^8 or 4.6x10^8 (see below)
Step-by-step explanation:
(4.8x10^8) - (2.2x10^6) + 1.2x10^4
(4.8x10^8) - (0.022x10^8) + (0.00012x10^8)
4.8
-0.22
+0.00012
4.58012
4.58012 x 10^8
There are only 2 significant digits (2.8x10^8) so if this is an answer relating to a scientific measurement, it would need to rounded to simply 4.6x10^8.

Write an equivalent expression to 16x + 20 using factoring.
Answer:
4(4x + 5)
Step-by-step explanation:
4 goes into both 16 and 20.
4×4 is 16 and
4×5 is 20.
When factoring you put the nunber you factored out typically, in front. Then the remaining factor goes in a set of parenthesis.
This is like undoing distributive property.
16x + 20
= 4(4x+5)
Take 2 common
2(8x+10)Again take two common
2(2(4x+5)Simplify

Sammy then $200 as a department store she bought three rings for $21 each and spend the rest on for equallypriced bracelets. How much did each bracelet cost?
Answer:
Step-by-step explanation:
3(21) + 4b = 200
63 + 4b = 200
4b = 200 - 63
4b = 137
b = 137/4
b = 34.25...so each bracelet (b) costs $ 34.25

My neighbor has both chickens and roosters. He has a total of 31 birds. The number of chickens is ten more than twice the number of roosters. How many chickens does he have?
Answer:
24
Step-by-step explanation:
You can use a simple equation for this:
c=chickens, r=roosters
c=10+2r, as "chickens is TEN MORE than TWICE the number of roosters,"
we can then do;
10+2r+r (the original number of roosters)=31
3r=21
r=7
BUT, WE'RE NOT LOOKING FOR ROOSTERS!
10+2r=24
What is the end behavior of the function f of x equals negative 4 times the cube root of x?
As x → –∞, f(x) → –∞, and as x → ∞, f(x) → ∞.
As x → –∞, f(x) → ∞, and as x → ∞, f(x) → –∞.
As x → –∞, f(x) → 0, and as x → ∞, f(x) → 0.

Assume that f(x) = 2x^2 + 4. The function f(x) + k, where k is a constant, is represented by the graph below. what effect did adding k have on the graph of f(x)‽
The effect of adding k on the graph of f(x) will shift the curve upward by k units on the xy-plane.
Shifting of quadratic graph is the vertical directionGiven the parent function of the given graph expressed as f(x) = 2x^2 + 4.
If this function is represented as f(x)+k, the addition of the constant "k" shows hat the function f(x) has been shifted vertically upwards by a factors of 'k'
Hence the effect of adding k on the graph of f(x) will shift the curve upward by k units on the xy-plane.

Can someone explain how to simplify radicals? (Please leave an example) Im so confused!!
Answer:
Sure!
Step-by-step explanation:
So a radical(or a root) is the opposite of the exponent(for example square root is the opposite of the square of a number). Graphically it's not but it's more simple to think of it like that. Simplifying integer radicals is simple. For example, the square of 11 is 121, so sqr121 (√121) is equal to 11. Other radicals/powers are similar. cuberoot27= 3 because 3^3 is 27. If you add variables, the same thing happens. You can think of the √ as a funnel where only the numbers "big enough" can leave. If you have √xy^2z^3,
the x would have to stay because it's only to the first power, the √y^2 would be reduced to just y, and one pair of zs can come out resulting in z√z. The final answer to √xy^2z^3 would be yz√xz. Hope that helps :)
three of the angles of a quadrilateral are 100, 104 and 44. what is the size of the 4th angle?
Answer:
112
Step-by-step explanation:
Sum of interior angles in quadrilaterial = 360
360 - 100 - 104 - 44 = 112
Step-by-step explanation:
Let the 4th angle = x
Now,
x + 100 + 104 + 44 = 360° ( the sum of interior angle of quadrilateral is 360°)
x + 248 = 360°
x = 360° - 248
x = 112
Hence, the fourth angle is 112....
