Answer:
6 and 0
Step-by-step explanation:
When we have f(-3) and f(6), that means we plug -3 and 6 in for x to solve for f(x):
f(-3) = (-2/3) * (-3) + 4 = 2 + 4 = 6
f(6) = (-2/3) * 6 + 4 = -4 + 4 = 0
The answers are thus 6 and 0.
Answer:
Population parameter
Step-by-step explanation:
We are given the following in the question:
74% of all instructors at your school teach 2 or more classes.
Parameter and statistic:
- Parameter is the value that describes a population.
- Population is the collection of all the possible observations of an event.
- Statistic is the quantitative value that describes a sample.
- A sample is a part of a population and is always smaller than a population.
Population:
all instructors at your school
Parameter:
74% of all the instructors at your school teach 2 or more classes
Thus, 74% describes the population that takes two or more classes.
Hence, it is a population parameter.
A=FALSE
B= TRUE (i beleive..not 100% sure)
C= TRUE
D= TRUE( not sure)
Answer:
12
Step-by-step explanation:
The expected value is 
, where n=148 is the sample size and 
.
We calculate the z-score of 37.5 using the formula:
From the standard normal distribution table, the area to the left of 1.43 is 0.9236.
.
The expected number of people in the sample with body temperatures above 37.5 degrees is 
We don't have a fractional human being, so the rule of thumb is to round up.
