Answer:
c
Step-by-step explanation:
Answer:
1
Step-by-step explanation:
m= (y-y1)/(x-x1)
Points are (-10, -20) and (1, -9)
m= (-20+9)/(-10-1)= (-11)/(-11)= 1
m=1 to replace ? mark
Answer:
II and III
Step-by-step explanation:
From statement II in the question, it is true that the standard deviations of two different samples from the same population may be the same. The population standard deviation is a fixed value calculated from every individual in the population. A sample standard deviation is calculated from only some of the individuals in a population.
Also from statement III, it is true that statistical inferences can be used to draw conclusions about the populations based on sample data. The mean of a population does not necessarily depends on the particular sample chosen. Therefore statement I is false.
Since south and west are at 90 degree angle that means we can use pythagorean theorem to find the distance.
It goes like this:
c^2 = a^2 + b^2
a = 3
b = 4
implementing this in pythagoras formula we get that c = 5
answer is 5 miles southwest
The answer of given equation is 
+ 5c +4
Step-by-step explanation:
By putting the given values of E and F we get,
E + F
=( 
) + (-
)
Here we will take the coefficient of same variable together
=(
) +( -2c +7c) +( -1+5)
= + 5c +4
Hope this helps you.
