The inequality that shows the scores Miriam could get to pass her math class is
<em><u>Solution:</u></em>
Given that To pass this year's math class, Miriam needs to earn at least an 82%
To find: Inequality that shows the scores Miriam could get to pass her math class
Let "x" be the Miriam's score in the math class
Given she should score at least 82 %
Therefore, we can frame a inequality as:
Here we used "greater than or equal to" , because she can score 82 % or more than 82 % also
The maximum score is 100 %
Hence we can frame a inequality as:
Here, we used "less than or equal to" , because she can score the maximum score of 100 % or less than 100 %
Combining both the inequalities we get,
All real numbers greater than or equal to 82% and less than or equal to 100%
Thus the required inequality is found
Answer:
0.36 = 36% probability that the land has oil and the test predicts it
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
45% chance that the land has oil.
This means that
He buys a kit that claims to have an 80% accuracy rate of indicating oil in the soil.
This means that
What is the probability that the land has oil and the test predicts it?
This is . So
0.36 = 36% probability that the land has oil and the test predicts it
