Use a proportion.
3 + 2 = 5
Let the number of SUVs be x.
SUVs to total = 3:5
SUVs to total = x:95
3/5 = x/95
5x = 3 * 95
x = 3 * 19
x = 57
95 - 57 = 38
57 SUVs and 38 sedans.
Answer:
16.6
Step-by-step explanation:
Answer:
senior tickets= $15
student tickets= $3
Step-by-step explanation:
1C+12S=51
(5C+6S=93)^-2
1C+12S=51
-10C-12S=-186
-9c=-135
divide both sides by -9
C= 15
to get the student tickets
51-15=36
12S=26
= $3
Answer:
1. 3$
Step-by-step explanation:
If A brand is 12$ per bottle, and B is 15x, then that is a 3$ difference.
Answer:
a) 0.80
b) 0.45
c) 0.55
Step-by-step explanation:
Given P(A) = 0.20 and P(B) = 0.35
Applying probability of success and failure; P(success) + P( failure) = 1
a) probability that the component does not fail the test = The component does not fail a particular test [P(success)] = 1 - P(A)
= 1 - 0.20 = 0.80
b) probability that the component works perfectly well
= P( the component works perfectly well) - P(component shows strain but does not fail test)
= 0.80 - 0.35 = 0.45
c) probability that the component either fails or shows strain in the test = 1 - P(the component works perfectly well)
= 1 - 0.45 = 0.55
