What is the geometric mean of the measures of the line segments A Dand DC? Show your work.
Answer:
AC2 = AB2 + BC2 ---> AC2 = 122 + 52 ---> AC = 13
AD / AB = AB / AC ---> AD / 12 = 12 / 13 ---> AD = 144/13
DC = AC - AD ---> DC = 13 - 144/13 ---> DC = 25/13
AD / DB = DB / DC ---> DB2 = AD · DC ---> DB2 = (144/13) · (25/13) ---> DB = 60/13
DB is the geometric mean of AD and DC.
Step-by-step explanation:
2(x2 − 16)
2(x + 4)(x + 4)
2(x + 4)(x − 4)
Answer:
2(x + 4)(x − 4)
Step-by-step explanation:
2x^2 − 32
Factor out 2.
2( x^2 -16)
The term inside the parentheses is the difference of squares.
(a^2 - b^2) = (a-b)(a+b)
2 ( x-4)(x+4)
Answer:
No, it is not.
Step-by-step explanation:
You graph the inequality by finding the boundary line, then shading the appropriate area.
Answer:
Null hypothesis: The American Society for Certified Public Accountants says the average starting salary of accountants who graduated in 2018 is $57,413
Alternate hypothesis: The American Society for Certified Public Accountants says the average starting salary of accountants who graduated in 2018 is less than or equal to $57,413
Step-by-step explanation:
A null hypothesis is a statement from a population parameter that is subject to testing. It is expressed with equality.
An alternate hypothesis is also a statement from the population parameter that negates the null hypothesis. It is expressed with inequality
