Answer:
9 pigs
Step-by-step explanation:
We have the following numbers of heads:
pigs (p) + chickens (c) = 16 animal heads (1)
And the following numbers of feet:
4p + 2c = 50 animal feet (2)
From equation (1):
p = 16 - c (3)
By entering equation (3) into (2) we have:
4(16 - c) + 2c = 50
64 - 4c + 2c = 50
c = 7
Now, entering the value of c into equation (3) we have the next value of p:
p = 16 - c
p = 16 - 7
p = 9
Therefore, the number of pigs that Henry has is 9.
I hope it helps you!
Answer:
Step-by-step explanation:
A gunner fires 10 bullets at a target, with the probability of hitting the target at each shot is p = 0.8. Know that, if all 10 bullets hit the target, the target is definitely destroyed. If 2-9 bullets hit the target, the target is destroyed with a probability of 80%. If only 1 bullet hits the target | then the target is destroyed with a probability of 20%. What is the probability that the target is destroyed?
Answer:
C. The distribution of the value of transaction accounts is a right-skewed distribution.
Step-by-step explanation:
Some definitions
A skewed right distribution is one in which the tail is on the right side. On simple words we have most of the values on the left part of the distribution.
And present the following property:
A skewed left distribution is one in which the tail is on the left side. On simple words we have most of the values on the left part of the distribution.
And present the following property:
On a symmetric distribution we satisfy 
For our case we have that 
and 
And we can see that 
then we can conclude that this distribution is skewed to the right. And the best option would be:
C. The distribution of the value of transaction accounts is a right-skewed distribution.
Answer:
a + 8
Step-by-step explanation:
Note that
(x + y)² = x² + 2xy + y²
= x² + y² + 2xy
= a + 2(4) = a + 8
12 are 27 1/4 and under and 8 are above 27 1/4
