Which frequency table is consistent with the histogram of weights of 86 different students, below?
Answers
Answer:
B
Step-by-step explanation:
The incorrect tables each have at least one flaw that makes it not match the histogram.
A. The relative frequency associated with 4 of 86 is about 0.047, not 0.055. The relative frequencies are incorrect.
B. this table matches the histogram
C. The "bins" are not of uniform width, nor are they centered on the same values as shown in the histogram.
D. The values in a cumulative frequency table should be non-decreasing. The table value of 24 should be 54.

Answer:
Step-by-step explanation:
The only one that has a chance of being correct is D. That's because the first term is correct and you have to assume that the second one is as well.
cubrt(512) = 8
The first term is (n + 8)
The second term is (n^2 - 8*n + 8^2) = n^2 - 8n + 64
All the other answers have the wrong first term
A: it should be n + 8 not n - 8
B and C are both wrong because the cube root of 512 is 8 not 4.

Step-by-step explanation:
This is Finite Math, I got this hehe :)
To find the answer, first you need to understand what R means.
It stands for "row". So R1 means "Row 1".
So: -3R1 + R3 means that you need to multiply -3 by all of the numbers in row 1 and then add all of the numbers in row 3
[0 3 1 -1 l 6]
[0 1 -1 -7 l 0]
[3 0 -2 2 l 12]
[4 1 5 3 l 7]
Then use ^^THAT^^ and apply the next set of instructions.
-4R1 + R4 means that you multiply -4 by all of the numbers in row 1 and then add all of the numbers in row 4:
[4 -11 1 7 l -17]
[0 1 -1 -7 l 0]
[3 0 -2 2 l 12]
[4 1 5 3 l 7]

Answers
Answer:
See below
Step-by-step explanation:
[tex] {5}^{2} + {2}^{2} = 25 + 4 = 29 \\ \\ {6}^{2} + {1}^{2} = 36 + 1 = 37[/tex]
The values are 29 = 5² + 2² and 37 = 6² + 1².
What is square of number?The definition of a square number states that they are numbers that have been multiplied by themselves. In other terms, a natural number is referred to as a square number if it is multiplied by itself.
Decimal squares are fairly simple to calculate, and the process is the same for both whole numbers (integers) and decimals.
Given numbers 29 and 37
to express in form of sum of two square
let = 29 = a² + b²
the perfect square number near 29 is 25
29 = 25 + 4
29 = 5² + 2²
and 37 = a² + b²
the perfect square near 37 is 36
37 = 36 + 1
37 = 6² + 1²
Hence the numbers in sum of two squares are,
29 = 5² + 2² and 37 = 6² + 1²
