Answer:
5 : 3
Step-by-step explanation:
Given in the question that,
total number of animal feet = 26
number of pig's feet = 20
number of chicken's feet = 6
As we know that pig have four legs and chicken have 2 legs so,
number of pigs in the farm = 20/4 = 5
number of chickens in the farm = 6/2 = 3
Questions says that there are 8 heads so we can confirm our calculations as
<h3>5 + 3 = 8</h3><h3 />
The ratio of the number of pigs to the number of chickens is
<h3>5 : 3 </h3>
The answer is all 3 of them. Transformations are isometries if distance between all dots are maintained the same. Easier way of spotting these is to check if all angles and all sides of surfaces are the same as before.
First and second we flipped horizontaly while last one we flipped both verticaly and horizontaly but sides and angles remained the same.
Step-by-step explanation:
4/9 is in lowest terms because it does not have any other common factor , other than 1 so it can't be reduced more .
A. True
Answer: a) 0.8413, b) 0.9987.
Step-by-step explanation:
Since we have given that
Mean = 3 pounds
Standard deviation = 0.25 pounds
n = 28 bricks
So, (a) What is the probability that all the bricks in the sample exceed 2.75 pounds?
b) What is the probability that the heaviest brick in the sample exceeds 3.75 pounds?
Hence, a) 0.8413, b) 0.9987.
Draw the two points in a rectangular coordinate system.
Draw a vector from the origin (0,0) until the point Y whose coordinates are (-1,3). Rotate the vector 90 degress anticlockwise.
You can see that the tip of the vector will fall in a point with coordinates (3,-1).
Then Y' is (3,-1).
Follow same procedure with point X(-6,2). The point of the vector will translate to X' with coordinates (-2,-6).
A 90 degrees anticlockwise rotation transforms coordinates (a,b) to (-b,a)
Then the answer is the option 3 - X'(-2,-6) Y'( 3,-1).
By convention if there is not indication the angles must be taken anticlockwise, but it would be better to indicate it.
If you rotate 90 degress clockwise the end points would be X'(2,6) Y'(3,-1).
