Answer:
y = -1/2x +5
Step-by-step explanation:
The perpendicular slope will be the negative reciprocal of the original slope
the reciprocal of 2 is 1/2, and the negative of that is -1/2
The answer would be (C).
To be fully simplified, the numerator and denominator must have a GCF of 1.
Answer (C) says 3/57. However, using the divisibility rule of 3 (add the digits together, and if the sum is a multiple of 3, then the number is as well), we see that 57 is divisible by 3, meaning this fraction is not simplified. The simplified version would be 1/19.
Answer:
Option is right
Step-by-step explanation:
Given that bella want to know what the students at her school think of her show. which is the BEST group to survey to find this information
For getting accurate results she must select a random sample without bias
For this option a will not serve since she selects only students she recognizes.
Option B may not be right, as during show on the face they may not give correct opinion
C is right as a random sample is taken
D is wrong as the first 30 students may not be at random.
So option C is right
Answer:
to know the summation of angles: (n-2)*180
here (n) represent numbers of sides
12)we have 5 sides (n=5)
(5-2)*180=540
x=540-(105+135+92+87)=121
13)we have 8 sides (n=8)
(8-2)*180=1080
x=1080-(116+158+141+124+136+132+129)=144
