Answer:
There are several kinds of mean in mathematics, especially in statistics. For a data set, the arithmetic mean, also called the expected value or average, is the central value of a discrete set of numbers: specifically, the sum of the values divided by the number of values.

miguel is working hard to save for a video game. he received $20 as a gift and gets $4 per week (x) in allowance. write the equation for the total amount of money he has saved, based on the number of weeks
Answer:
5
Step-by-step explanation:
x represents how much money he gets per week and if he got twenty dollars all together and gets four dollars a week then x represents 5 because 5 times 4 equals twenty and in the problem the letter that represents the number of weeks is x divide twenty by x if the number is 4 divide 20 by four and you'll get 5

34
Answer:
34
Step-by-step explanation:
Since AD is a straight line the sum of ABC and DBC would be equal to 180°
2x + 4 + 3x + 6 = 180 add like terms
5x + 10 = 180 subtract 10 from both sides
5x = 170 divide both sides by 5
x = 34

What is the solution to -4 (2x +6)=-24
Answer:
x=0
Step-by-step explanation:
Distribute -4
-8x - 24 = -24
Add 24 to both sides
-8x = 0
x=0
Answer:
x=0
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−4(2x+6)=−24
(−4)(2x)+(−4)(6)=−24(Distribute)
−8x+−24=−24
−8x−24=−24
Step 2: Add 24 to both sides.
−8x−24+24=−24+24
−8x=0
Step 3: Divide both sides by -8.
−8x
−8

the total "cast" of a laptop computer is $1278.24 the local sales tax rate is 7.6% what is the retail price.
Answer:
x = 1187.96
Step-by-step explanation:
Let x = price before tax
tax = x* 7.6%
tax = .076x
The cost of the computer is price before tax plus tax
cost = x + .076x
cost = 1.076x
1278.24 = 1.076x
Divide each side by 1.076
1278.24/1.076 = 1.076x/1.076
x=1187.9553
Rounding to the nearest cent
x = 1187.96
PLEASE HELP I ONLY HAVE 10 minutes !!! (will give brainliest )........Find the perimeter of AABC with vertices A(-5, -5), B(3, -5), and C(-5, 1).
(picture is included)
Answer:
24
Step-by-step explanation:
So to start we need to find the length of the sides. luckily, since this is a right triangle we can subtract the x values on line AB to get 8 and we can subtract the y values on line AC to get 6. Now that we know two lengths we can use [tex]A^{2} +B^{2} =C^{2}[/tex] to find the last length.
When we plug in the two known lengths we get [tex]8^{2} +6^{2} =c^{2}[/tex] which can be simplified to [tex]64+36=c^{2}[/tex] and then simplified again to be [tex]100=c^{2}[/tex]. We can then take the square root of 100 to know that c=10.
Finally, we can add [tex]10+8+6[/tex] to get 24.
use the given manimum and maximum data entries, and the number of classes, to find he class width, the lower class limits, and the upper class limits
minimum= 9 maximum= 66, 6 classes
The lower class and upper class limits are {9, 19, 29, 39, 49} and {10, 20, 30, 40, 50} respectively for the given class.
What is the class width of a given data set?The class width of a given class is the ratio of the difference between maximum and minimum to the number of classes.
Given, minimum= 9 maximum= 66, and classes = 6.
Therefore, class width
= [tex]\frac{maximum - minimum}{classes}[/tex]
= [tex]\frac{66 - 9}{6}[/tex]
= [tex]\frac{57}{6}[/tex]
= 9.5
Therefore, class width is 9.5.
Now, the lower class limits = {9, 19, 29, 39, 49}
The upper class limits = {10, 20, 30, 40, 50}

Classify the following angles as acute, Right, obtuse, straight and reflex angles.
30°,40°,120°,90°,180°,650,225°,1650,300°,170°,2150,315°,75°,
340º,170°
Answer:
any angle under 90 degrees is acute. A right angle is 90 degrees always, and obtuse angles are always above 90 degrees. Straight angles are always 180 degrees. A reflex angle is more than 180 degrees but less than 360 degrees. Hope this helps.
