Answer:
they are neither. if they were parallel they would be the same. if they were perpendicular they would be opposite reciprocal. So it is neither
this is a. same area this is correct I think so
Um not really a specific enough question for a good answer, but I'll give it a go
all you have to do is use long division and divide the numerator by the denominator (top by bottom)
most often the result will not be pretty so round appropriately (i recommend tenths or hundredths)
for exampe
25/11
use some handy division skills, and you'll get about 2.27
note that improper fractions mean that the decimal form will always be greater than 1, or less than -1
Answer:
There appears to be a difference between the pulse rates from samples of adult males and females. The average pulse rate of males is 63.75 while that of females is 75.875.
Coefficient of Variation (male) = 33.44%
Coefficient of variation (female) = 28.35%
Step-by-step explanation:
Mean (male) = 
Mean (female) = 
Standard Deviation (male) = 
Standard Deviation (female) = 
Coefficient of Variation = 
For male, CV = 
%
For female, CV = 
%
Comparison : Pulse rates of males has more variability than that of females since it has a greater coefficient of variation.
Answer:
x = 2
Step-by-step explanation:
Since we know one root is -3, we know one factor of the equation is (x+3)
From there we can use the factor we know to factor the rest of the equation:
x^2 + x - 6 = (x+3) * ?
Since know -6 is just 3 * -2 and since 3-2 is 1,
(x+3)(x-2) = x^2 + x - 6
From there,
x - 2 = 0
x = 2
