Answer:
0,05
Step-by-step explanation:
1)First, Let’s find the mean of the data table
12 + 10 + 12 + 6 + 8 + 4 + 2 + 12 = 66
66 ÷ 8 = 8,25
2)12 - 8,25 = 3,75
10 - 8,25 = 1,25
12 - 8,25 = 3,75
6 - 8,25 = -1,75
8 - 8,25 = -0,75
4 - 8,25 = -3,75
2 - 8,25 = -5,75
12 - 8,25 = 3,75
3) 3,75 + 1,25 + 3,75 - 1,75 - 0,85 - 3,75 - 5,75 + 3,75 = 0,4
0,4 ÷ 8 = 0,05
Answer:
Step-by-step explanation:
Looking at the given graph, the slope of the line is expressed as
Slope = (y2 - y1)/(x2 - x1)
y2 = 19.5
y1 = 9.5
x2 = 6
x1 = 1
Slope = (19.5 - 9.5)/(6-1)
Slope = 10/5 = 2
The successive terms is increasing by 2
The formula for the nth term of an arithmetic sequence is expressed as
Tn = a + (n - 1)d
Where
a is the first term of the sequence
n is the number of terms in the sequence.
d is the common difference.
From the information given,
a = 9.5
Tn = an
d = 2
The explicit rule for the arithmetic sequence will be
an = 9.5 + 2(n-1)
Answer:
Correct answer: Two decimal places to the right
Step-by-step explanation:
We will set the classic proportion:
29,235 - 100%
371 - x%
29,235 : 371 = 100 : x ⇒ 29,235 · x = 371 · 100
x = (371/ 29,235) · 100 = 0.0127 · 100 = 1.27%
x = 1.27%
You divide first number by the second and then multiply with 100,
which is the same as moving the decimal point two places to the right.
God is with you!!!
S + 4t = r
subtract 4t from both sides
s = r - 4t answer
