Answer: 7 -1/6
Step-by-step explanation:
Multiply the denominator and numerator (1/3) by 2 to get 2/6, then do 1/6-2/6, which gives you a negative. Then subtract your whole numbers (14-7) to get 7 -1/6
Answer:
$12
Step-by-step explanation:
because,
365=year
365*4= 1460
17,520/1460=$12
Answer:
True
Step-by-step explanation:
Simple random sampling chooses at random members of the population. This allows all members an equal probability of being selected for the sample.
Answer:
arc ADB = 270°
Step-by-step explanation:
Arc ADB is the remainder of the circle after subtracting 90° arc AB. Its measure is ...
ADB = 360° -90° = 270°
The nth term of the geometric sequence is:
an=ar^(n-1)
where
a=first term
r=common ratio
n=nth term
from the question:
120=ar(3-1)
120=ar^2
a=120/(r^2)....i
also:
76.8=ar^(5-1)
76.8=ar^4
a=76.8/r^4.....i
thus from i and ii
120/r^2=76.8/r^4
from above we can have:
120=76.8/r²
120r²=76.8
r²=76.8/120
r²=0.64
r=√0.64
r=0.8
hence:
a=120/(0.64)=187.5
therefore the formula for the series will be:
an=187.5r^0.8
