Answers
Answer:
84%
Step-by-step explanation:
The mean has 50% below the mean and 50 % above the mean
The mean is 103.47
The standard deviation is 4.07
Add the mean and the standard deviation
103.47+4.07 = 107.54
We want to know how much data is below the mean plus one standard deviation
Within one standard deviation is 68% , but that is on both sides, we are only needed on the right side so we need 1/2 of the 68 = 34
50+34 = 84
The stander deviation 4.07
1/2*68=34
The percent of time will be 80
34+50=80

Solve 8x - 5y = 18 for y.
y=(Use integers or fractions for any numbers in the expression.)
Answers
Answer:
y=8/5x + 18/5
Step-by-step explanation:
subtract 8x on both sides which ends up looking like:
-5y = 18 -8x
divide -5 on both sides which ends up like:
y= 8/5x - 18/5
then u simplify, but there's not need for that because it's already simplified.
Find the 59th term of the arithmetic sequence 26,17,8
Answers
Answer:
-496
Step-by-step explanation:
The direct formula for the nth term of an arithmetic sequence is given by the formula:
[tex]x_n=a\cdot d(n-1)[/tex]
Where a is the initial term, d is the common ratio, and n is the nth term.
Let's find a and d.
From the sequence, we can see that the initial term or a is 26.
Also, each subsequent term is 9 less than the previous term. In other words, our common ratio is -9.
Therefore, our direct formula is:
[tex]x_n=26-9(n-1)[/tex]
To find the 59th term, substitute 59 for n:
[tex]x_{59}=26-9(59-1)[/tex]
Subtract:
[tex]x_{59}=26-9(58)[/tex]
Multiply:
[tex]x_{59}=26-522[/tex]
Subtract:
[tex]x_{59}=-496[/tex]
So, the 59th term is -496.
And we're done!

3.4 - 2.8d +2.8d - 1.3
Answers
Answer:
2.1
Step-by-step explanation:
Simplifying
3.4 + -2.8d + 2.8d + -1.3 = 0
Reorder the terms:
3.4 + -1.3 + -2.8d + 2.8d = 0
Combine like terms: 3.4 + -1.3 = 2.1
2.1 + -2.8d + 2.8d = 0
Combine like terms: -2.8d + 2.8d = 0.0
2.1 + 0.0 = 0
2.1 = 0
Solving
2.1 = 0
Couldn't find a variable to solve for.

2a + b = 3 and a - 3b = 5
Answers
Answer:
a= 2 b=-1
Step-by-step explanation:
a-3b=5
or, a= 5+3b_(i)
substituting value of a in 2a+b=3,
2×(5+3b)+b=3
or, 10+6b+b=3
or, 7b=3-10
or, 7b=-7
b= -1
substituting value of b in(i),
a=5+3b
=5+3×(-1)
=5-3
=2
