Find the mean of:
3.8, 4.0, 4.1, 3.9, 4.2
Answers
Answer:
4
Step-by-step explanation:
Set of Data (Prioritized):
3.8, 3.9, 4.0, 4.1, 4.2
To find the mean:
Add up all the scores and divide the total by the number of scores.
(3.8 + 3.9 + 4.0 + 4.1 + 4.2) ÷ 5
= 4
Therefore, the mean is equal to 4.

What is a good estimate and the actual measurement for this angle measurement? A. 110 and 109 B. 95 and 96 C. 90 and 91 D. 70 and 71
Answers
The good estimate, as well as the actual measurement for the given angle, is 110° and 109°.
What is a good estimate?
In construction, a good estimate is an approximate value of a number that makes it faster to make cognitive deductions.
On the other hand, the actual measurement is the exact measurement of an angle or shape when the appropriate measuring tools are being used.
From the diagram, the angle is an obtuse angle because it is more than 90° since it extends more than its perpendicular axis(90°), but it is less than 180°.
Therefore, we can conclude that the good estimate, as well as the actual measurement for the given angle, is 110° and 109°.

Solve 12x^2+5x-4=12^2x+6
Answers
Answer:
okay so we need to solve for x.
--
FIRST STEP: 12x^2+5x-4=12^2x+6 would turn into x2 + 5x - 4 = 2x + 6 so it'd have equal bases.
SECOND STEP: move any number with "x" in it to the left side. it ends up as x2 + 3x - 4 = 6
THEN, we use the AC method to eliminate any unnecessary numbers.
you should end up with ( x - 2) (x + 5) = 0
SO, the answer is your third option. ( x = 2, x = -5)
Step-by-step explanation:
Answer:
x = 2, x = -5
Step-by-step explanation:
[tex] {12}^{ {x}^{2} + 5x - 4 } = {12}^{2x + 6} \\ (Bases\: are\: equal\: so\: exponents\: \\will\:also\:be \: equal) \\ \implies \: {x}^{2} + 5x - 4 = 2x + 6 \\ \\ \implies \: {x}^{2} + 5x - 4 - 2x - 6 = 0\\ \\ \implies \: {x}^{2} + 5x - 2x - 4- 6 = 0\\ \\ \implies \: {x}^{2} + 5x - 2x - 10 = 0\\ \\ \implies \:x(x + 5) - 2(x + 5) = 0\\ \\ \implies \:(x + 5)(x - 2) = 0 \\ \\ \implies \:x + 5 = 0 \: \: or \: \: x - 2 = 0 \\ \\ \implies \:x = - 5 \: \: or \: \: x = 2[/tex]

What is the transformation of a graph?Transformation is rearranging a graph by a given rule it could be either increment of coordinate or decrement or reflection.
If we reflect any graph about y = x then the coordinate will interchange it that (x,y) → (y,x).
As per the given triangles M and M'.
If we take point B then the all vertices of triangle M and M' will make a straight line with point B as shown below.
Thus, point B will be the center of dilation.
Hence "The triangle M"s center of dilation will be at B".

Answer:

Step-by-step explanation:
12/20 = 3/x
solve for x
x=5
Answer: x is 5
Step-by-step explanation: These two triangles are similar (meaning same shape but different size.) To find x, we must first decrease the scaling. The original triangle is 3 and x sides. Being scaled, it is now 12 and 20. 12 divided by 4 is 3, so that's the first side, and being equivalent, 20 divided by 4 is 5, so therefore the triangle has been scaled by 4 units. Therefore x side is 5.

To model the problem containing an unknown number, translate the statement into an equation.
Sixteen is five less than a number.
Which steps would you take to translate the statement?
Replace “is” with =, “less than” with –, and “a number” with n to get 16 = 5 – n.
Replace “is” with =, “less than” with +, and “a number” with n to get 16 = n + 5.
Replace “is” with =, “less than” with –, and “a number” with n to get 16 = n – 5.
Replace “is” with =, “less than” with ÷, and “a number” with n to get 16 = 5 ÷ n.
Answers
Answer:
The correct option would be the 3rd one
If you want to find 5 less than a number you are subtracting
so 5 less than 20 would be 15, so 20 - 5
since 16 is five less that means whatever the equation equals it will be 16 which is why 16 is in the first part
