Part a: Area of habitat - Area of field = Area of mowed portion.
Part b: Area of mowed portion: 4x(b - x)
Explain the term area of the square?The maximum number of unit squares forming a square is referred to as the square's area. In other terms, it is described as the area that the square occupies.For the stated question:
Part a:
The complete area is given as: Area of habitat.
The area kept for birds: Area of mowed portion
Central unmowed portion: area of field
Thus,
Area of habitat - Area of field = Area of mowed portion
Part b: Area of mowed portion: 4x(b - x)
Proof:
b² - (b - 2x)² = [b - (b - 2x)] [b + (b - 2x)]
= [b - b + 2x] [b + b - 2x]
= (2x)(2b - 2x)
= 4x(b - x)
Thus, the Area of mowed portion: 4x(b - x).

1. Is a triangle with side lengths 6, 4, 3 a right triangle? Why or why
not?
Answers
Answer:
no
Step-by-step explanation:
Using the converse of Pythagoras' identity.
If the square of the longest side is equal to the sum of the squares on the other 2 sides then the triangle is right.
longest side = 6 , then 6² = 36
4² + 3² = 16 + 9 = 25
Since 4² + 3² ≠ 6² then triangle is not right.

Answers
Answer:
B. Isosceles right triangle.
Step-by-step explanation:
The triangle given has two sides that have equal lengths. It also has a right angle.
An Isosceles triangle has two equal side lengths.
Therefore, since the triangle above has a right angle and has two equal side lengths, based on the side lengths, it can can be classified as an isosceles right triangle.

The probability of a head is 0.27. The coin is thrown 200 times. Write an
estimate for the amount of tails
Answers
Answer:
The estimate for the amount of tails is 146.
Step-by-step explanation:
For each throw, there are only two possible outcomes. Either it is a head, or it is tails. Throws are independent. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
Can be approximated to a normal distribution, using the expected value and the standard deviation.
The expected value of the binomial distribution is:
[tex]E(X) = np[/tex]
The standard deviation of the binomial distribution is:
[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]
The probability of a head is 0.27.
This means that the probability of tails is [tex]p = 1 - 0.27 = 0.73[/tex]
The coin is thrown 200 times.
This means that [tex]n = 200[/tex]
Write an estimate for the amount of tails
This is the expected value, so:
[tex]E(X) = np = 200*0.73 = 146[/tex]
The estimate for the amount of tails is 146.
find y and round to the nearest tenth. thank you
Answers
Answer and Step-by-step explanation:
31 degrees on the top would be equal to the angle in between x and 600ft, by the interior angles theorem.
That means we can solve for y using the trigonometric function of tangent.
[tex]tan(31) = \frac{y}{600}[/tex]
Multiply by 600 to both sides, then use a calculator to solve.
600(tan(31)) = x
x = 360.5163714
x ≈ 360.5 is the answer.

Some biologists believe the evolution of handedness is linked to complex behaviors such as tool-use. Under this theory, handedness would be genetically passed on from parents to children. That is, left-handed parents would be more likely to have lefthanded children than right-handed parents. An alternate theory asserts that handedness should be random, with left- and right-handedness equally likely. In a recent study using a simple random sample of n  76 right-handed parents, 50 of the children born were right-handed. ( pˆ =0.658 .) Suppose handedness is a random occurrence with either hand equally likely to be dominant, implying that the probability of a right-handed offspring is p =0.50.
Required:
a. Show that it is reasonable to approximate the sampling distribution of p̂ using a normal distribution.
b. Assuming left- and right-handed children are equally likely from right-handed parents, what is the probability of observing a sample proportion of at least p̂ =0.658 ?
Answers
Answer:
a) Since both np >= 5 and n(1-p) >= 5, it is reasonable to approximate the sampling distribution of p^‚ using a normal distribution.
b) 0.5 = 50% probability of observing a sample proportion of at 0.658.
Step-by-step explanation:
a. Show that it is reasonable to approximate the sampling distribution of p̂ using a normal distribution.
We need that:
np >= 5
n(1-p) >= 5
Sample of 76, 50 of the children were born were right-handed.
So [tex]n = 76, p = \frac{50}{76} = 0.658[/tex]
np = 76*0.658 >= 5
n(1-p) = 76*0.342 >= 5
Since both np >= 5 and n(1-p) >= 5, it is reasonable to approximate the sampling distribution of p^‚ using a normal distribution.
b. Assuming left- and right-handed children are equally likely from right-handed parents, what is the probability of observing a sample proportion of at least p̂ =0.658 ?
This is the mean, so 50% below and 50% above.
0.5 = 50% probability of observing a sample proportion of at 0.658.

What is a function?A function is an equation for which any x that can be put into the equation will produce exactly one output such as y out of the equation.
Given is a graph, we need to find its equation,
So, the graph is U-shaped, therefore, the leading coefficient is, a > 0
also, the graph does not have a zero at the origin,
The function which could possibly create the graph is the option; A.
F(x) = x⁷-x³-3x²+3
The leading coefficient is 1 > 0
The function has no factors of x = 0
The function has a linear factor.
Hence, the functions that could have created this graph is f(x) = x⁷-x³-3x²+3
