Answer:
Two tailed
Step-by-step explanation:
Given that a security expert claims that exactly 13% of all homeowners have a home security alarm.
Here we have to check whether the contention of security expert is correct or not
The test is to be done for the proportion of homeowners who have a home security alarm to total homeowners.
Let p be the proportion.
For this we set up hypotheses as:
This is a two tailed test
Because alternate is for not equal to. If alternate is for > or < we say one tailed and if not equal to we say two tailed.
The circumference of a circle with radius
is
. If the length of the radius is tripled, then the circumference becomes
, which is just 3 times the original circle's circumference.
Answer:
x = 13
Step-by-step explanation:
The sum of angle measures in a triangle is 180°.
m∠M + m∠L + m∠N = 180°
(4x-4)° + (3x+12)° + (6x+3)° = 180°
13x +11 = 180 . . . . . . collect terms, divide by °
13x = 169 . . . . . . . . . subtract 11
x = 13 . . . . . . . . . . . . . divide by 13
Answer: A, D, and E
Step-by-step explanation:
Basically, you want to divide each of these answers by 5. Which ever one gives you a solid number (meaning no decimals) then that would be one option.
Hope this helps!
