<span> f(x) = 3(1/2)x is not properly formed; if you meant exponentiation here, please write the function as
f(x) = </span><span> f(x) = 3(1/2)^x.
The range is the set of all possible values of y (that is, all possible values of f(x). Try out a few x values and see what you get:
f(-5) = 3(1/2)^5 (note that this is positive)
f(0) = 3(1/2)^0 = 3 (this is positive)
f(4) = 3(1/2)^4 = 3/16 (this is positive)
There is no x value for which f is negative, and none for which f is 0. Given this info, what do YOU think the range of </span><span> f(x) = 3(1/2)^x is?
Write it in the form (a,b).</span>

:proportion of male smoker lung deaths is same for the four given tar level categories.
:proportion of male smoker lung deaths is not the same for the four given tar level categories.
Expected frequency=1177/4=294.25
Tar level Observed Freq.(O) Expected Freq.(E) (O-E)^2/E
0-7 107 294.25 120.435
8-14 375 294.25 5.643
15-21 553 294.25 227.533
>=22 183 294.25 42.061
Total= 1177 1177 395.673
Total chi square score=395.673
df=4-1=3
p-value=CHIDIST(395.673,3)<0.001
p-value<0.001,Reject null hypothesis.
There is sufficient evidence that the proportion of male smoker lung deaths is not the same for the four given tar level categories.

778 mile x ? hours = 50 miles per hours
Therefore,
778 miles /50 mph = 15.56 hours
15.56 hours to the nearest tenth is 15.6 hours
15.56 hours = (15.56 x 60) 933.6 minutes
933.6 minutes to the nearest minute is 934 minutes
Answer:
x = 3 and y = 1
Step-by-step explanation:
Give system of equations are :
8x-9y=15 ...(1)
−x+4y=1 ...(2)
Multiply equation (2) by 8.
−8x+32y=8 ..(3)
Add equation (1) and (3).
8x-9y -8x + 32y = 15+8
23y = 23
y = 1
Put the value of y in equation (2).
−x+4(1)=1
-x = -4+1
x = 3
Hence, the values of x and y are 3 and 1.
