There are 7 parent tigers
Parents = 7
7 tigers each have 7 children. That means there's total of 7 × 7 children.
Children = 7 × 7 = 49
Each child has 7 friends. That means there's total of 49 × 7 friends.
Friends = 49 × 7 = 343
Total = 7 + 49 +343 = 399 TIGERS
I'm not a tiger so I'm not counting myself.
Answer:
x- coordinate of P is - 6
Step-by-step explanation:
The coordinates of any point in the form of an ordered pair (x, y )
Point P has coordinates P (- 6, 2 )
It is just asking you what the y-value is when x=6. In this case it is about 2.5
6 less than the product of 7 and this number is 85.
6 less than (the product of (7 and this number)) is 85.
6 less than (the product of 7 and x) = 85
6 less than (7 * x) = 85
(7 * x) - 6 = 85
Now you solve! Make sure that whatever you do to one side you also do to the other:
7x - 6 = 85
7x - 6 + 6 = 85 + 6
7x = 91
7x /7 = 91 /7
x = 13
Hope this helps! :)
Answer:
The standard deviation of x is 2.8867
Step-by-step explanation:
The standard deviation of variable x that follows a uniform distribution is calculated as:
Where (a,b) is the interval where x is defined.
So, replacing a by -4 and b by 6, the standard deviation is:
