This is a part of both female/ male. The male has sperm when released, and the female produces a egg which lead to reproduction.
Answer:
true
Step-by-step explanation:
The reason is that when the male and female have sex the male releases sperm into the female the sperm goes to the female egg then she gets pregnet a couple of days later. Therefore that equals reproduction.

The average starting salary for this year's graduates of a large community college is $30,000 with a standard deviation of $8,000. Furthermore, it is known that the starting salaries are normally distributed. a. What is the probability that a randomly selected LU graduate will have a starting salary of at least $30,400? b. Individuals with starting salaries of less than $15,600 receive a low income tax break. What percentage of the graduates will receive the tax break? c. what are the minimum and the maximum starting salaries of the middle 95% of the LU graduates? d. If 303 of the recent graduates have salaries of at least $43,120, how many students graduated this year from this university?
Answer:
0.048 ; 0.03593 ; (14320, 45680) ; 6000
Step-by-step explanation:
Given a normal distribution :
Mean salary (m) = $30000
Standard deviation (s) = $8000
A.) probability of having a starting salary of atleast 30400
P(x ≥ 30400)
Obtain the standardized value (Z) :
Z = (x - m) / s
Z = (30400 - 30000) / 8000
Z = 400 / 8000 = 0.05
P(Z ≥ 0.05) = 0.48006 (Z probability calculator)
b. Individuals with starting salaries of less than $15,600 receive a low income tax break. What percentage of the graduates will receive the tax break?
P(X < 15600)
Obtain the standardized value (Z) :
Z = (x - m) / s
Z = (15600 - 30000) / 8000
Z = - 14400 / 8000 = - 1.8
P(Z < - 1.8) = 0.03593
c. what are the minimum and the maximum starting salaries of the middle 95% of the LU graduates?
Zscore which corresponds to 0.95 is 1.96
Minimum:
-1.96 = (x - 30000) / 8000
-15680 = x - 30000
x = 14320
Maximum :
1.96 = (x - 30000) / 8000
15680 = x - 30000
x = 45680
d. If 303 of the recent graduates have salaries of at least $43,120, how many students graduated this year from this university?
P(X ≥ 43120)
Z = (43120 - 30000) / 8000
Z = 13120 / 8000
Z = 1.64
P(Z ≥ 1.64) = 0.050503
Hence,
0.050503 = 303
1 = x
x = 303 / 0.05050
= 6000

A farmer wants to build a rectangular pen which will be bounded on one side by a river and on the other three sides by a single-strand electric fence. If the farmer has 40 meters of wire to use, what is the largest area that the farmer can enclose?
Answer:
A) Dimensions;
Length = 20 m and width = 10 m
B) A_max = 200 m²
Step-by-step explanation:
Let x and y represent width and length respectively.
He has 40 metres to use and he wants to enclose 3 sides.
Thus;
2x + y = 40 - - - - (eq 1)
Area of a rectangle = length x width
Thus;
A = xy - - - (eq 2)
From equation 1;
Y = 40 - 2x
Plugging this for y in eq 2;
A = x(40 - 2x)
A = 40x - 2x²
The parabola opens downwards and so the x-value of the maximum point is;
x = -b/2a
Thus;
x = -40/2(-2)
x = 10 m
Put 10 for x in eq 1 to get;
2(10) + y = 40
20 + y = 40
y = 40 - 20
y = 20m
Thus, maximum area is;
A_max = 10 × 20
A_max = 200 m²
The area of the pen is the product of its dimensions
The largest area the farmer can enclose is 200 square meters
The perimeter of the pen is given as:
[tex]\mathbf{P = 40}[/tex]
Because one side of the fence is covered by a river, the perimeter would be:
[tex]\mathbf{2x + y = 40}[/tex]
Make y the subject
[tex]\mathbf{y = 40 - 2x}[/tex]
The area of the pen is:
[tex]\mathbf{A = xy}[/tex]
Substitute [tex]\mathbf{y = 40 - 2x}[/tex]
[tex]\mathbf{A = x(40 - 2x)}[/tex]
Expand
[tex]\mathbf{A = 40x - 2x^2}[/tex]
Differentiate
[tex]\mathbf{A' = 40 - 4x}[/tex]
Set to 0
[tex]\mathbf{ 40 - 4x = 0}[/tex]
Rewrite as:
[tex]\mathbf{ 4x = 40}[/tex]
Divide through by 4
[tex]\mathbf{x = 10}[/tex]
Substitute 10 for x in [tex]\mathbf{A = x(40 - 2x)}[/tex]
[tex]\mathbf{A = 10 \times (40 - 2(10))}[/tex]
[tex]\mathbf{A = 200}[/tex]
Hence, the largest area the farmer can enclose is 200 square meters

Find the product
-3(5) I need help
Answer:
-15
Step-by-step explanation:
() means to multiply
So, -3(5) = -3 x 5 = -15
Answer: -15
The question asks you to find the "product," which means the result of multiplying. Both the word "product" and the parentheses indicate that you have to multiply.
Since it's a negative (-) multiplied by a positive (+), your product will be negative (-).
So, -3(5) = -15.

Suppose that the flying hours for aircraft operated by regional airlines in the U.S. during 2006 are normally distributed with mean 2500 and standard deviation 400. Find the number of flying hours such that about 97.5% of the aircraft has flying hours exceeding this number.
A) 1,700
B) 2,100
C) 2.500
D) 2,900
E) 3,300
Answer:
Step-by-step explanation:
Given that :
Mean (μ) = 2500
Standard deviation (σ) = 400
P = 97.5% = 0.975
Zscore corresponding to p(z > x) = 0.975
Z = - 1.96 ( Z probability calculator)
Using the relation :
Zscore = (score (x) - μ) / σ
-1.96 = (x - 2500) / 400
x - 2500 = 400 * - 1.96
x - 2500 = - 784
x = - 784 + 2500
x = 1716
Hence, number of flying hours required is 1716
