It will take him at least a year.
This is simple!
To begin with, arrange all the numbers in order.
#1
5, 5, 20, 20, 25, 30, 35Mean: add all the numbers together and divide it by how many numbers are there
5+5+20+20+25+30+35=140
there are 7 numbers
Mean:
= 20
Median: The middle number, if the set of numbers have an odd number, then the one in between is the median, if there it is an even number, then the mean of the two in-between numbers is the median.
Median: 20
Mode: The most repeated numbers
Mode: 5 and 20
Range: Highest number - lowest number
Range: 35 - 5
30#2
Order: 44, 48, 48, 49, 59, 61, 63, 68Mean: 440 (sum of all numbers)
there are 8 numbers in total

=
55
Median: there are 8 numbers so, the mean of the in-between numbers will be the median
49+59=108
2 numbers

=
54
Mode: 48
Range = 68 - 44 = 24
Answer:
33.3%
Step-by-step explanation:
1. Formula: difference/original
2. 120 - 80 = 40
3. 40/120
4. 1/3
5. 1/3 = 33.3%
Answer: (5,7) (6,5) (7,3) (8,1)
Step-by-step explanation:
take the given x values and plug them into the parent function
Answer:
The vertex angle = 28 degrees.
Each of the base angles = 76 degrees.
Step-by-step explanation:
The 2 base angles of an isosceles triangle are equal.
The relation between the vertex angle and one of the base angles is as follows:
2x + y = 180 where x = the measure of a base angle and y = the measure of the vertex angle.
Also, from the information given in the question:
x = 3y - 8
so we have the system of equations:
2x + y = 180........(1)
x - 3y = -8...........(2)
Multiply equation (2) by -2:
-2x + 6y = 16......(3)
Adding (1) and (3):
7y = 196
y = 28.
Substituting for y in equation (2):
x - 3(28) = -8
x = -8 + 84
x = 76.
