<h2>
AREA</h2>
The formula for finding area of a square is:
In a square, all the sides are the same. Each side is 6 meters long. Plug in 6 to the formula.
Multiply:
The area of the square is 36 m²
<h2>PERIMETER</h2>
Perimeter is the distance around a shape. To find perimeter, you have to add all all the side lengths. The formula for finding perimeter is:
Remember that squares have 4 sides, and all length(s) and width(s) measure the same. The length and width measure the same. Plug in the numbers into the formula:
Simplify:
Add:
The perimeter of the square is 24 m
Answer:
proportional relationship
Step-by-step explanation:
proportional relationships are straight lines that go thru the origin
This is a straight line going thru (0,0) so it is a proportional relationship
Answer and Explanation:
Given : Five males with an X-linked genetic disorder have one child each. The random variable x is the number of children among the five who inherit the X-linked genetic disorder.
To find :
a. Does the table show a probability distribution?
b. Find the mean and standard deviation of the random variable x.
Solution :
a) To determine that table shows a probability distribution we add up all six probabilities if the sum is 1 then it is a valid distribution.
Yes it is a probability distribution.
b) First we create the table as per requirements,
x P(x) xP(x) x² x²P(x)
0 0.029 0 0 0
1 0.147 0.147 1 0.147
2 0.324 0.648 4 1.296
3 0.324 0.972 9 2.916
4 0.147 0.588 16 2.352
5 0.029 0.145 25 0.725
∑P(x)=1 ∑xP(x)=2.5 ∑x²P(x)=7.436
The mean of the random variable is
The standard deviation of the random sample is
Therefore, The mean is 2.5 and the standard deviation is 1.08.
Answer:
y=10
Step-by-step explanation:
Substitute -4 in place of x
y = -4*-4-6
y=10
since u know that there is 60 minutes in a hour do 60 times 3 and u will get 180.then do 180 divided by28 and u will get ur final answer which is 6 minutes and 12 seconds
