Put them in order from least to greatest and find the median (middle) Everything to the right of the dash is the lower quartile, everything to the left is the higher quartile. Then find the median (middle) of the lower quartile.
Answer:
3.67
Step-by-step explanation:
Answer:
(1) For x = –12, g (x) = -9
For x = –9, g (x) = -3
For x = –6, g (x) = 3
For x = –3, g (x) = 9
(2) The principal amount of money is $80.
Step-by-step explanation:
(1)
The expression of g (x) is,
The complete table is:
x g (x)
-15
-12
-9
-6
-3
0
(2)
The formula for simple interest is:
Given:
I = $40
r = 10%
t = 5 years.
Compute the value of <em>P</em> as follows:
Thus, the principal amount of money is $80.
From Pythagorean Identities <span><span><span>sin^2</span>x</span>+<span><span>cos^2</span>x</span>=1</span>
and from that identities we can have <span><span>sinx</span>+<span>cosx</span>=1</span>, taking <span><span>sinx</span>=1−<span>cosx</span></span> and substitute in the equation
<span><span>sinx</span>+<span>cosx</span>=1</span>
<span><span>(1−<span>cosx</span>)</span>+<span>cosx</span>=1</span>
Remove the parenthesis
<span>1−<span>cosx</span>+<span>cosx</span>=1</span>
cancel <span>cosx</span>
<span>1=1</span>
The domain of the exponential function is all real numbers.
