Answer:
-5+(-7)+9+(-3) = -6
Step-by-step explanation:
We need to add the following i.e.
-5+(-7)+9+(-3)
We know that, +(-) = - (minus)
So,
-5-7+9-3 = -12+6
= -6
So, the value of the given expression is equal to -6.
Answer:
B
Step-by-step explanation:
Answer:
0.07
a. the distribution will be a normal distribution.
c. we would suspicious ins there is a 2 % chance of getting the required value.
Step-by-step explanation:
Let the number of times, t be = 50
Assuming that the die is fair
standard deviation = 1.71
mean = 3.5
suppose we want tp find the probability of a 2 showing. The solution becomes:
probability = 
c. the mean of rolls will be 0.07
Point slope form is
y-y1=m(x-x1)
where slope=m
and (x1,y1) is a given point
slope=(y2-y1)/(x2-x1)
slope=(6-7)/(-8-(-5))=-1/(-8+5)=-1/-3=1/3
pick any point
(x,y)
(-5,7)
y-7=1/3(x+5) or
y-6=1/3(x+8)
