We are given a table of frequencies, so in order to find probability associated with it, we need to start by adding all the numbers in the frequency, since that would give us the totals:
We add :
7.7 + 8.2 + 24.1 + 25.6 + 51.5 + 29. 4 = 146.5
Now, notice that they ask you to find the probability associated with a voter chosen at random to be in a group DIFFERENT from the range 21 to 24, That means the complementary of this range, which is therefore
146.5 - 8.2 = 138.3 (since 8.2 is the frequency for the 21 - 24 years/age range.
Then the probability is the quotient:
138.3 / 146.5 = 0.9440273 which in percent terms is 94.4 %
If you teacher wants the probaility in decimal (math) form, use 0.944.
If he/she wants it in percent form, use 94.403% (using
Answer:
Divide both sides by 3.
(x+2)^2=16
Square root both sides.
x+2= ± 4 (plus OR minus, can be either so we have to include both)
Minus 2 from both sides.
x=-2 ± 4
Add and minus the 4 to -2.
x = -2-4 = -6 and x=-2+4 = 2
Answer:
This would be the commutative property because in either order the sum will always be the same.
You were asking about the property type, right?
Answer:
y = 1/2x - 6
Step-by-step explanation:
y2 - y1 / x2 - x1
-2 - (-5) / 8 - 2
3 / 6
= 1/2
y = 1/2x + b
-5 = 1/2(2) + b
-5 = 1 + b
-6 = b
Answer:
403.75
Step-by-step explanation:
we can write the following equation
.75m+145=price
we just need to plug in 345 for m
.75*345+145=price
put this into a calculator and get 403.75
