Option c. is correct
Step-by-step explanation:
The standard deviation is a measure of the amount of dispersion in a set of values.
Mean of a normal distribution (m) = 154
Standard deviation (s) = 15
z-score = 2.2
To find: value (x) that has a z-score of 2.2
z-score is given by
Put
Option c.is correct
Answer:
The value of x in the given figure is,
Step-by-step explanation:
Complementary angle states that the two angles sum up to 90 degree.
From the given figure
and are complementary angles.
by definition of complementary angles;
Subtract from both sides we get;
Simplify:
therefore, the value of x in the given figure is,
Inequalities are used to relate expression with unequal values
The inequality that describes the scenario is:
The baseball cards, you have received are:
The total baseball cards, you received are:
So, we have:
You want to have a total of 500 or more before 18.
This means that:
Where c represents the number of baseball cards, you need to collect on your own
Substitute
Collect like terms
Hence, the inequality that describes the scenario is:
