Answer:
set two equation of line y=ax+b and y=cx+d
when these two lines are perpendicular to each other, then a*c=(-1)
set answer is y=ax+b
we can know that a=1/6
bring in a=1/6 and(-4,5)
5=(1/6)*(-4)+b
=>5=(-2/3)=b
=>b=5 2/3
answer is y=(1/6)x+5 2/3
Answer:
A) rational number
Step-by-step explanation:
56 is a rational number because it can be expressed as the quotient of two integers like 56 ÷ 1.
Pretty sure it’s D but if it is not then I don’t know
Answer: 0.00102%
Step-by-step explanation:
Given : Human body temperatures are normally distributed with a mean of
and a standard deviation of 
A hospital uses
as the lowest temperature considered to be a fever.
Let x be the random variable that represents the human body temperatures.

For x= 100.6, 
Using normal distribution table for z-values for right-tailed area ,
P(x>100.6)=
Hence, the required probability = 0.00102%
