|-6b| <= 60
b <= 60/6
b<= 10
and
b>= 60/-6
b>= -10
answer:
b>= - 10 and b<= 10
or
-10 <= b <= 10
Answer: Yes, because with each round table, the amount of chair goes up by 5.
True or false?
ok, so just use your head and use this simple memory tool
for remembering inequalities, the aligator eats the bigger number
x>y means x is biger than y
x<y means x is smaller than y or y is bigger than x
remember: the farther to the right a number is, the bigger it is
8<9
and
-10<-3 since -3 is farther to right than -10
so see them
b. 5>7, duh, false
c. 15≥17, are you kidding me, false
d. true
e. nay, no negative number is ever greater than a positive, false
f. true, -2 is farther to the right than -13 is
g. x>4, x is any number bigger than 4, not including 4
h. x is any number bigger than 8, not including 8
i. x is less than or equal to -4, so it can be -5, or even -4
Answer: 0.345
Step-by-step explanation:
Given : The incomes of families in Newport Harbor are normally distributed with Mean : 
and Standard deviation : 
Samples size : n=4
Let x be the random variable that represents the incomes of families in Newport Harbor.
The z-statistic :-
For x= $800,000
By using the standard normal distribution table , we have
The probability that the average income of these 4 families exceeds $800,000 :-
Hence, the probability that the average income of these 4 families exceeds $800,000 =0.345
The answer is x(x-8)(x+8)
Here is the process;
x^3-64x
x(x^2-64)
You know that it will be a x- and a x+ becuase there is no middle x value
x(x-)(x+)
x(x-8)(x+8)
