lindsey was the top scorer in a women's professional basketball league for the 2006 regular season, with a total of 862 points. The number of two-point field goals that lidnsey made was 71 less than double the number of three-point field goals she made. The number of free throws (each worth one point) she made was 21 less than the number of two-point field goals she made. Find how many free throws, two-point field goals, and three-point field goals lindsey made during the 2006 regular season.
Lindsey made 35 free throws, 143 two-point field goals, and 107 three-point field goals during the 2006 regular season.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Let's denote the number of two-point field goals Lindsey made by x, and the number of three-point field goals she made by y.
x + y + (x+y-71)/2 + (x+y-71)/2 - 21 = 862 (total points equation)
x = 2y - 71 (two-point field goals equation)
Simplifying the first equation and substituting the second equation, we get:
3x + 3y = 1964
Substituting x = 2y - 71 into this equation, we get:
3(2y-71) + 3y = 1964
Solving for y, we get:
y = 107
Substituting this value into the equation x = 2y - 71, we get:
x = 143
Now, (x + y - 71)/2 - 21 = (143 + 107 - 71)/2 - 21 = 35
Therefore, Lindsey made 35 free throws, 143 two-point field goals, and 107 three-point field goals during the 2006 regular season.

Determine algebraically whether the function is even, odd, or neither?
f(x)=3 x 3+5
The function f(x) = 3x³ + 5 is neither even nor odd. To determine whether a function is even or odd, you need to check how the function behaves when x is replaced with -x.
To determine whether the given function is even, odd, or neither, we need to check the following conditions:
Even function: If f(-x) = f(x) for all x in the domain of f, then the function is even.
Odd function: If f(-x) = -f(x) for all x in the domain of f, then the function is odd.
Let's check these conditions for the given function:
f(x) = 3x³ + 5
f(-x) = 3(-x)³ + 5 = -3x³ + 5
f(x) = 3x³ + 5
Since f(-x) is not equal to f(x), the function is not even.
f(-x) = 3(-x)^3 + 5 = -3x^3 + 5
-f(x) = -(3x^3 + 5) = -3x^3 - 5
Since f(-x) is not equal to -f(x), the function is not odd.
Therefore, the given function is neither even nor odd.

Enter your answer and show all the steps that you use to solve this problem in the space provided. Use the 30°-60°-90° Triangle Theorem to find the answer.
Find the value of x. If your answer is not an integer, leave it in simplest radical form. The diagram is not drawn to scale.
Answer: 5[tex]\sqrt{3}[/tex]
Step-by-step explanation:
The 30-60-90 triangle rule states that the hypotenuse is twice the length of the shortest leg (which would be 5) and the longer leg is [tex]\sqrt{3}[/tex] times the length of the shorter leg.
Since we are trying to find x we would use the rule for the longer leg
so 5 * [tex]\sqrt{3}[/tex] would just be 5[tex]\sqrt{3}[/tex]
The value of the x is 5√3 after we successfully do the application of the 30°-60°-90° Triangle theorem.
What is Triangle theorem?The 30°-60°-90° Triangle Theorem states that in such a triangle, the side opposite the 30° angle is half the length of the hypotenuse, and the side opposite the 60° angle is the product of the length of the hypotenuse and the square root of 3 divided by 2.
here, we have,
Using this theorem, we can write:
y = hypotenuse
Opposite of 30° angle = 5 = hypotenuse/2
Opposite of 60° angle = x = hypotenuse × (√(3)/2)
Solving for the hypotenuse in terms of y from the first equation, we get:
hypotenuse = 5×2 = 10
Substituting this value into the third equation, we get:
x = 10 × (√(3)/2) = 5 × √(3)
Hence, The value of the x is 5√3 after we successfully do the application of the 30°-60°-90° Triangle theorem.

At a railway station, trains are either eastbound or westbound.
An eastbound train leaves the station every 25 minutes.
A westbound train leaves the station every 45 minutes.
An eastbound train and a westbound train both leave the station at 8 ar
When is the next time that two trains leave the station together?
If both bound trains leave together at 8, they will also start together at 11:45 the next time.
What is the LCM (least common multiple) of two numbers?The LCM of two numbers is the smallest possible number that is divisible by both of those two numbers. The prime factorization and the division methods are generally used to find the LCM.
An eastbound train leaves the station every 25 minutes whereas a westbound train leaves the station every 45 minutes.
These two types of trains will leave the station together if the time is divisible by both 25 and 45, that is, the LCM of them.
Find the LCM of 25 and 45 using the prime factorization method.
25=5×5
45=3×3×5
LCM(25,45)=3×3×5×5
=225
As 1 hour equals 60 minutes, it follows that 225 minutes equals 3 hours and 45 minutes.
If 3 hours 45 minutes is added to 8 hours, it will be 11 hours 45 minutes.
Therefore, the two trains leave the station together at 11 hours 45 minutes.

Step-by-step explanation:
Answer: Square root of 288, or estimated 16.97
Step-by-step explanation:
Conveniently, the points form a diagonal line as you show, so we can use the Pythagorean Theorem to find the distance.
The x-component of this is the distance between -6 and 6, which is 12, and the y-component is again the distance between -6 and 6, which is also 12.

(a) Describe the shape, center, and variability of the sampling distribution of for samples of size 10. Interpret the
standard deviation.
The shape of the sampling distribution will be approximately normal, with a center at 40 inches and a standard deviation of 1.645 inches.
What is the shape, center, and variability of the sampling distribution?The mean of the sampling distribution of the sample mean height for samples of size 10 will also be 40 inches.
The standard deviation of the sampling distribution of the sample mean height can be calculated as:
σ/sqrt(n) = 5.2/sqrt(10) = 1.645
So, the shape of the sampling distribution will be approximately normal, with a center at 40 inches and a standard deviation of 1.645 inches.
The variability of the sampling distribution is smaller than the variability of the population distribution, because the standard error is smaller than the population standard deviation.
