Answer:
n = 16
Step-by-step explanation:
The equation is,
→ √n = 4
Solving for the value of n,
→ √n = 4
→ n = 4²
→ [ n = 16 ]
Hence, the value of n is 16.
The length of a rectangular deck is five times its width if the decks perimeter is 24 feet what is the decks area
The area of the rectangular deck is 20 ft²
How to find the area of a rectangle?The length of a rectangular deck is five times its width.
Therefore,
l = 5w
perimeter of the rectangular deck = 2(l + w)
where
l = lengthw = widthTherefore,
24 = 2(5w + w)
24 = 2 × 6w
12w = 24
divide both sides by 12
w = 24 / 12
w = 2
Therefore,
area of the rectangular deck = lw
area of the rectangular deck = 2 × 10
area of the rectangular deck = 20 ft²
Therefore, the area of the rectangular deck is 20 ft²

Find the measure of the indicated angle to the nearest degree.
By using a trigonometric relation, we can see that the missing angle is a = 41.1°
How to find the missing angle on the right triangle?In the image we have a right triangle where we know the measures of the 3 sides and we want to find an interior angle.
These measures are:
Hypotenuse: 73 units.Opposite cathetus: 48 units.Adjacent cathetus: 55 units.Now we can use the trigonometric relation:
Cos(a) = (adjacent cathetus)/(hypotenuse)
Where a is the angle we want to get, so we can rewrite:
Cos(a) = 55/73
Now, if we apply the inverse cosine function in both sides, we get:
Acos(Cos(a)) = Acos( 55/73)
a = Acos(55/73) = 41.1°
By using a trigonometric relation, we can see that the missing angle on the right triangle is a = 41.1°

25°
y
x 120°
y=[? ]º
Answer:9514 1404 393
Answer:
y = 95°
x = 60°
Step-by-step explanation:
The applicable theorem is the one that says the exterior angle (120°) is the sum of the remote interior angles:
120° = 25° +y
95° = y . . . . . . . . . . subtract 25° from both sides
_____
If you like, you can get there by calculating x (or not):
x = 180° -120°
y = 180° -25° -x = 180° -25° -(180° -120°)
y = 120° -25° . . . . . simplify — notice we didn't actually have to compute x

What expression is equivalent to 5^0 • 5^3 A: 0. B:1. C:5^3. D:1/5^3
Suppose X is normally distributed with a mean of 5 and a standard deviation of 0.4. Assume that P(X ≤ X₀) = P(Z ≤ 1.3). Which of the following equations should be solved to get the value of X₀?
For the standard deviation, from the equation find the value of X₀ is 10.2
What is Standard Deviation ?
The standard deviation measures the degree of variation or dispersion in a set of values. A low standard deviation indicates that the values tend to be close to the mean (also known as the expected value) of the set, whereas a high standard deviation indicates that the values are dispersed over a wider range.
Given
Z = 1.3
μ = 5 , σ = 0.4
Now for X₀
Z = X₀ -X / σ
1.3 = X₀ - 5 / 0.4
X₀ = 10.2
Hence, X₀ = 10.2

solve system of equations by using elimination method. (solve for (x,y,z) please explain the steps im so confused.
4x-y-2z=-8
-2x+4z=-4
x+2y=6
The solution to the given system of equations is x = -2, y = 4, and z = -2. That is, the solution is (-2, 4, -2)
From the question, we are to solve the given system of equations
The given system of equations is
4x - y -2z = -8 ------------ (1)
-2x + 4z = -4 ------------ (2)
x + 2y = 6 ------------ (3)
From equation (2)
-2x + 4z = -4
4z = -4 + 2x
Divide through by 2
2z = -2 + x ----------- (4)
From equation (3)
x + 2y = 6
2y = 6 - x
y = 3 - 1/2(x) ---------- (5)
Substitute equations (4) and (5) into equation (1)
4x - y -2z = -8
4x -(3 -1/2(x)) - (-2 +x) = -8
4x -3 + 1/2(x) + 2 - x = -8
Multiply through by 2
8x - 6 + x + 4 -2x = -16
Collect like terms
8x + x -2x = -16 + 6 - 4
7x = -14
x = -14/7
x = -2
Substitute the value of x into equation (4)
2z = -2 + x
2z = -2 + (-2)
2z = -2 - 2
2z = -4
z = -4/2
z = -2
Substitute the value of x into equation (5)
y = 3 - 1/2(x)
y = 3 - 1/2(-2)
y = 3 + 1
y = 4
Hence, the solution to the given system of equations is x = -2, y = 4, and z = -2. That is, (-2, 4, -2)

the perimeter of a college basketball court is 96 meters
and the length is 3 meters less then twice the width.
What are the demensions.
Answer:
Width=17m and Length=31m
Step-by-step explanation:
The perimeter of basketball court is rectangle in shape and is 96 m.
let us assume width be x m
so accordingly length will be 2*x-3=2x-3m
Perimeter= 2*(length+width)
96=2*(2x-3+x)
96=2*(3x-3)
96=6x-6
6x=102
x=102/6
x= 17
so, the width is 17m
and length is 2x-3=2*17-3=31m

FIND THE 100TH LINE SEGMENT
CUBE #1 HAS 4 LINES
CUBE #2 HAS 12
CUBE #3 HAS 24
WHATS THE 100TH LINE SEGMENT USING NTH TERM.
PICTURE BELOW!
Answer:
20,200
Step-by-step explanation:
Let the number of lines in each cube be a term in the sequence:
4, 12, 24, 40, ...
Work out the differences between the terms until the differences are the same:
[tex]4 \underset{+8}{\longrightarrow} 12 \underset{+12}{\longrightarrow} 24 \underset{+16}{\longrightarrow} 40[/tex]
[tex]8 \underset{+4}{\longrightarrow} 12 \underset{+4}{\longrightarrow} 16[/tex]
As the second differences are the same, the sequence is quadratic and will contain an n² term. The coefficient of n² is always half of the second difference. Therefore, the coefficient of n² is 2.
To work out the nth term of the sequence, write out the numbers in the sequence 2n² and compare this sequence with the given sequence.
[tex]\begin{array}{|c|c|c|c|c|}\cline{1-5} n & 1 & 2 & 3 & 4\\\cline{1-5}2n^2 & 2 & 8 & 18 & 32\\\cline{1-5}\sf operation & +2&+4&+6&+8 \\\cline{1-5}\sf sequence & 4 & 12 & 24 & 40\\\cline{1-5}\end{array}[/tex]
From inspection of the table, we can see that the "operation" is to add 2n to 2n².
Therefore, the nth term is:
[tex]a_n=2n^2+2n[/tex]
To find the number of lines in the 100th cube, substitute n = 100 into the equation for the nth term:
[tex]\begin{aligned}n=100 \implies a_{100} & = 2(100)^2+2(100)\\& = 2(10000)+200)\\& = 20000+200\\& = 20200\end{aligned}[/tex]
Therefore, the 100th cube has 20,200 lines.

Substitutes are two goods that can be used in place of each other for a similar purpose.
In this case, if the price of blue jeans increases, consumers may switch to buying more tennis shoes instead, since they serve a similar purpose in terms of clothing.
Complements are two goods that are used together, such as peanut butter and jelly.
Normal goods are goods whose demand increases as income increases, while inferior goods are goods whose demand decreases as income increases.
Hence, If an increase in the price of blue jeans leads to an increase in the demand for tennis shoes, then blue jeans and tennis shoes are substitutes.

A box plot, ajso referred to as a box and whisker plot, is a type of chart that is widely used in data analysis in descriptive statistics.
Box plots use the data's quartiles (or percentiles) and averages to visually depict the distribution of numerical data and skewness.Box plots display a data set's minimum score, first (lower) quartile, median, third (upper), and maximum scores in a five-number summary.The median is the average value from a set of data and is shown by the line that divides the box into two parts.Almost half the scores are greater than or equal to this value and half are less than the median value.Now we know that from the box plot that the median is almost at the Centre , and both the third quartile and first quartiles are almost at equal distance from median, thus we can say that it is almost symmetric and normally distributed.
