The steps of the solution in the above photo
I hope that is useful for you :)
For this case, the first thing you should do is define a variable.
We have then:
x: number of passengers remaining who can board the plane.
We have as data:
1) They can board up to 149 passengers
2) There are 96 passengers currently aboard.
Writing inequality we have:
Answer:
An inequality that can be used to determine how many more people can board is:
Answer:
x=112
Step-by-step explanation:
x/2-18=38
first add +18
x/2=56
now multiply by 2
x=112
6)The experimental probability is 39%.(39/100(100)).
7) The theoretical probability is theoretical. This is when something should happen without taking external forces into account. Experimental probability is taking the external forces into account which is why the probability is not as clean cut.
The theoretical probability should be 33%.
The experimental probability is actually 39%.
Answer:
a. Non proportional
b. Proportional
c. Non proportional
Step-by-step explanation:
Here, we want to determine if each situation is proportional or not
a) Non-proportional
This is because the amount y paid in a month will be;
y = 1400x + 150
Since the amount paid is not solely dependent on the number of months, then we do not have a proportional relationship
b) proportional
y = 3/4x
The value of y is dependent solely on that of x, so the relationship is proportional
c) non proportional
Since the value of y is not solely entirely dependent on x value, then the relationship is not proportional
