Answer:
<h2>f(n) = 0.15n + 0.35</h2>
Step-by-step explanation:
The sequence of the problem above is an arithmetic sequence
For an nth term in an arithmetic sequence
F(n) = a + ( n - 1)d
where a is the first term
n is the number of terms
d is the common difference
To find the equation first find the common difference
0.65 - 0.5 = 0.15 or 0.80 - 0.65 = 0.15
The first term is 0.5
Substitute the values into the above formula
That's
f(n) = 0.5 + (n - 1)0.15
f(n) = 0.5 + 0.15n - 0.15
The final answer is
<h3>f(n) = 0.15n + 0.35</h3>
Hope this helps you
The answer
let A= 2^3 and B=3^2
the main formula is as following:
a^n = axaxax ....xa (n times), for all n upper than or equal 1
for example
a^3 = a x ax a
in our case
A= 2^3 = 2x2x2= 4x2 =8
B=3^2 = 3x 3= 9
so, Luther's evaluation was wrong, by contrast <span>Wade evaluated 32 as 9 correctly

sadly i haven’t learned this so i can’t help you with the answers themselves but a graphing utility you could use is a graphing calculator or a graphing calculator online i know one called desmos.com just not sure if it has the intersect feature so i recommend graphing calculator
Answer:
20
Step-by-step explanation:
x^2+18x-160
If you put this into your calculator or desmos, you will get a parabola. You want to know the value of x when y=600. You can look at the table for the graph or scan to where y = 600. The value of x is 20 at that point.
To check you can plug 20 in for x. When you do that, y = 600.
Answer:
c) 0.22
Step-by-step explanation:
<u>Explanation</u>:-
A random sample of 500 army recruits has a mean height of 68 inches with a standard deviation of 2.5 inches.
The sample size 'n' = 500
Given the mean of the sample = 68 inches
Given standard deviation = 2.5 inches
The 95% of confidence interval ∝ = 1.96
Margin of error = 0.2191 ≅0.22
<u>Conclusion</u>:-
The Margin of error at 95% of confidence intervals = 0.22
