P + 2c = 3.25 Start with these two equations
3p + 4c = 7.25
p = -2c + 3.25 Solve for one variable
3(-2c +3.25) + 4c = 7.25 Substitute
-6c + 9.75 + 4c = 7.25
-2c = -2
c = 1
p + 2(1) = 3.25 Substitute
p + 2 = 3.25
p = 1.25
A bag of chips costs $1
A pickle costs $1.25
Probability is given by the formula:
Probability=(number of favorable outcomes)/(Total number of possible outcomes)
thus;
Given that t<span>he frequency table was made using a bag containing slips of paper that are numbered 1, 2, 3, 4, or 5.
then:
1] Probability of obtaining 1
Number of favorable outcome=4
Total number of outcomes=(4+12+20+32+12)=80
P(1)=4/80=0.05
2]Probability of obtaining a 2
Number of favorable outcomes=12
thus
P(2)=12/80=0.15
3] Probability of obtaining a 3
Number of favorable outcomes=20
thus
P(3)=20/80=0.25
4] Probability of obtaining a 4
Number of favorable outcomes=32
thus
P(4)=32/40=0.8
5] Probability of obtaining a 5
Number of favorable outcomes=12
thus
P(5)=12/80=0.15</span>
Steps to solve:
f(x) = |x| + 1; x = -3
~Substitute
f(-3) = |-3| + 1
<em>When you take the absolute value of a number it changes it to a positive number regarding it sign.</em>
~Take the absolute value of -3
f(-3) = 3 + 1
~Simplify
f(-3) = 4
Best of Luck!
