To square means to multiply something by itself. A variable is a letter such as x. So a squared variable=x×x=x^2.
I hope that helped.
Answer:
1c
1d
Step-by-step explanation:
From the question we are told that
The probability of telesales representative making a sale on a customer call is
The mean is
Generally the distribution of sales call made by a telesales representative follows a binomial distribution
i.e
and the probability distribution function for binomial distribution is
Here C stands for combination hence we are going to be making use of the combination function in our calculators
Generally the mean is mathematically represented as
=>
=>
Generally the least number of calls that need to be made by a representative for the probability of at least 1 sale to exceed 0.95 is mathematically represented as
=>
=>
=>
=>
taking natural log of both sides
=>
Answer:
The answer to your question is below
Step-by-step explanation:
Domain is the values of x the function can take D = (-2, 2]
Range is the values of y the function can take R = [-5, 4]
a) From the graph we got f(-1) = -5
b) From the graph we got f(0) = -4
c) From the graph we got f(1) = -5
d) From the graph we got f(2) = 4
Answer:
C
Step-by-step explanation:
Answer:
y=1
Step-by-step explanation:
you can use those points to find the slope
use the equation then plug in the numbers
so (1-1)/(-8-7) = 0/15 so the slope is zero meaning it is a horizontal line which we can tell logically because the y coordinates of both points are 1.
so if you plug those numbers into the formula y=mx+b where m is slope and b is the y intercept then
you get y=0*x+1
then 0*x is just zero and it goes away so the equation for this line is y=1
