The equation is:
(5*x)+7>=32
Answer: x >= 5
Answer:
f(-9)=2.6
Step-by-step explanation:
Plug in -9 for x
f(-9)=3/5(-9)+8
Combine like terms
f(-9)=-5.4+8
f(-9)=2.6
Answer:
C
Step-by-step explanation:
In this question, we are asked to select which of the options best answer the question.
We proceed as follows;
Using the information given,
Each of the 110 students in a statistics class selects a random sample of 35 Quiz scores
from a population of 5000 scores. They are not given the population mean and standard deviation.
Now, using these data, each student then construct a 90% confidence interval for µ which is the average Quiz score in the population of 5000 students.
By definition, the population mean values will definitely be within the limits of this
confidence interval.
Thus, the correct answer is, Option (c)
Answer:
NOPE, NOT EQUAL!!
Step-by-step explanation:
To find f(-20), first figure out which piece x = -20 fits with.
Since -20 < -12, x = -20 first in the domain used by the third piece.
For f(-20), treat this function as if it was just f(x) = 3x-7.
f(-20) = 3(-20) -7
= -60 - 7
= -67
