Step-by-step explanation:
Answer:
A binomial probability density function should be used because the question asks for determining the probability that exactly 10 students wear glasses.
Step-by-step explanation:
A binomial probability density function is used when we want to know the probability of an exact value.
A cumulative distribution function is used when we want to know the probability of less than or equal to a value.
Using order of operations you would multiply first giving you 15. So 47-15=32.
The correlation coefficient is -0.2907 or about -0.29
Answer:
x = - 3
Step-by-step explanation:
Given
12x + 7x = 5x - 42, that is
19x = 5x - 42 ( subtract 5x from both sides )
14x = - 42 ( divide both sides by 14 )
x = - 3
