The possible number of combinations are 9,720.
What is combination?In mathematics, a combination is a way of selecting a subset of items from a larger set, where the order of selection does not matter. The number of combinations of size k that can be chosen from a set of n items is denoted by the symbol C(n,k) or sometimes by ⁿCk, and is given by the formula:
C(n,k) = n! / (k! ×(n - k)!)
Define number?A number is a mathematical concept used to represent quantity or value. It can be a whole number, such as 1, 2, 3, or a decimal, such as 1.5 or 3.14. Numbers are used in various mathematical operations, such as addition, subtraction, multiplication, and division. They are also used in everyday life for counting and measuring.
There are a total of 9,720 possible combinations for a 4-number computer cable lock where each space can be any number 0-9, except for the restriction that all four numbers cannot be the same. To arrive at this number, we can first calculate the total number of possible combinations without the restriction, which is 10⁴ = 10,000. Then we subtract the number of combinations where all four numbers are the same, which is simply 10 (i.e. 0000, 1111, 2222, etc.), to get 9,990. Finally, we subtract the number of combinations where all four numbers are the same and also subtract the number of combinations where three out of four numbers are the same (which is simply 10×4 = 40 since there are 10 possible values for the repeated number and 4 possible positions for it), which gives us a final count of 9,720.

What does this problem mean |x+3| if x>5
Answer:
x+3 . . . . if x > 5
Step-by-step explanation:
You want the meaning of |x+3| if x > 5.
Absolute valueThe absolute value function is a piecewise defined function:
[tex]y=|x|=\begin{cases}-x&\text{for }x < 0\\x&\text{for }x\ge0\end{cases}[/tex]
ApplicationThe expression (x+3) is zero when x=-3. So, your absolute value function will have the piecewise definition ...
[tex]|x+3|=\begin{cases}-(x+3)&\text{for }x < -3\\x+3&\text{for }x\ge-3\end{cases}[/tex]
You are interested in the value for x > 5, which is definitely greater than -3. That means only the second part of this definition is applicable.
x+3 . . . . if x > 5

D. The graph of g(x) is the graph of f(x) horizontally compressed by a
factor of 5.
cu
(b) The graph of g(x) is the graph of f(x) vertically stretched by a factor of 5.
Comparing the functions f(x) and g(x)From the question, we have the following parameters that can be used in our computation:
f(x) = x²
g(x) = (1/5x)²
The graph of g(x) is the graph of f(x) vertically stretched by a factor of 5.
To see this, we can rewrite g(x) as g(x) = (1/5)²(x²) = (1/5²)f(x).
This means that g(x) is equal to f(x) scaled vertically by a factor of 5² = 25.
Therefore, the graph of g(x) will be the same shape as the graph of f(x), but stretched vertically by a factor of 25.

A random number generator picks a number from 7 to 69 in a uniform manner. Round answers to 4 decimal places when possible.
Find the maximum for the lower quartile
(100PTS)
Answer:
The lower quartile corresponds to the 25th percentile of the data set. To find the maximum value for the lower quartile, we need to find the largest number that is at or below the 25th percentile.
The range of the numbers that the random number generator can pick is 69 - 7 + 1 = 63. The 25th percentile corresponds to the value that is 25% of the way through this range, which is:
0.25 * 63 = 15.75
Since we can't pick a fractional number, we need to round down to 15. Therefore, the maximum value for the lower quartile is 15.

Find the exact length of the curve. x = et − t, y = 4et/2, 0 ≤ t ≤ 6
Length of the curve is e² - 1 .
In arithmetic, a function from a group X to a group Y assigns to every part of X precisely one part of Y. The set X is termed the domain of the function and therefore the set Y is termed the codomain of the function
Main body:
A parametric curve is a function expressed in components form, such that;
x = f(t) , y = g(t).
The length of a parametric curve on the interval a ≤ t ≤ b is given by the definite integral :
L = [tex]\int\limits^a_b {\sqrt{\frac{dx}{dt}^2 + {\frac{dy}{dt}^2 } } } \, dx[/tex]
Let's begin by getting the first derivative of the components of the function with respect to the variable t.
x = e^t - t
dx / dt = e^t−1
And, y = 4 e^t/2
dy /dt = 2 e^t/2
Substitute the derivatives into the following definite integral which computes the length of the parametric curve on the interval
[a,b]=[0,2].
L = [tex]\int\limits^a_b {\sqrt{\frac{dx}{dt}^2 + {\frac{dy}{dt}^2 } } } \, dx[/tex]
L= [tex]\int\limits^2_0 {\sqrt{\ (e^t - 1)^2 + ({\(2e^{t/2}) ^2 } } } \, dx[/tex]
L = [tex]\int\limits^2_0 {e^t - 1} \, dx[/tex]
Evaluate the solution at the limits of integration to get the length.
L = (e² - 1 )- (e⁰ - 1)
L = e² - 1 - 1 + 1
L= e² - 1
Hence , length of the curve is e² - 1 .

According to the USDA, a small family farm has an average area of 231 acres.
a. What is this area in square miles? Use this fact that 1 square mile is 640 acres.
b. What is this area in square feet? Recall: 1 mile = 5,280 ft.
Answer:
Therefore, the area of a small family farm in square feet is 9,923,640.
Step-by-step explanation:
a. To convert acres to square miles, we divide the number of acres by 640:
231 acres / 640 acres/square mile = 0.36 square miles
Therefore, the area of a small family farm in square miles is 0.36.
b. To convert acres to square feet, we first need to convert acres to square yards (since there are 9 square feet in a square yard):
231 acres x 4840 square yards/acre x 9 square feet/square yard = 9,923,640 square feet
Therefore, the area of a small family farm in square feet is 9,923,640.

A passbook savings account has a rate of 5%. Find the effective annual yield, rounded to the nearest tenth of a percent, if the interest is compounded semiannually.
Answer: 5.1%
Step-by-step explanation:
The formula for calculating the effective annual yield when the interest is compounded semiannually is given by:
(1 + (r/n))^n - 1
where r is the annual interest rate and n is the number of times the interest is compounded in a year.
In this case, r = 5% and n = 2 (since the interest is compounded semiannually). Substituting these values into the formula, we get:
(1 + (0.05/2))^2 - 1
= (1.025)^2 - 1
= 1.050625 - 1
= 0.050625
Multiplying this value by 100 gives the effective annual yield as a percentage:
0.050625 x 100 = 5.0625%
Rounding this to the nearest tenth of a percent, we get:
Effective annual yield = 5.1%
Therefore, the effective annual yield for the given savings account, rounded to the nearest tenth of a percent, is 5.1%.

Every page of the newspaper is a rectangle measuring 43 cm by 28 cm, both correct to the nearest
centimetre.
Calculate the upper bound of the area of a page.
Answer: 1204 cm²
Step-by-step explanation:
The upper bound of the area of a page would be the area of a rectangle with the upper bound of the length and width measurements.
Given that each page of the newspaper is a rectangle measuring 43 cm by 28 cm, both correct to the nearest centimetre, the upper bound of the length would be 43.5 cm (since we round up to the nearest centimetre) and the upper bound of the width would be 28.5 cm.
Therefore, the upper bound of the area of a page would be:
43.5 cm x 28.5 cm = 1240.25 cm²
Rounding this value to the nearest whole number, we get:

good buy electronics has a markup of 150% on a keyboard that cost the retailer $25. find the retail "selling" price and show your work
The retail selling price of the keyboard is $43.75.
What is the percentage?
A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.
To find the retail selling price of the keyboard, we need to add the markup to the cost of the keyboard.
The markup of 150% means that the retailer is adding 150% of the cost to the selling price.
To calculate this, we can first find the dollar amount of the markup:
Markup = 150% of $25
Markup = 0.5 * 150 * $25
Markup = $18.75
This means that the retailer is adding $18.75 to the cost of the keyboard to get the selling price. To find the selling price, we can add the markup to the cost:
Selling price = Cost + Markup
Selling price = $25 + $18.75
Selling price = $43.75

what is the slope of this function
A. 1/2
B. -2
C. 2
D. -1/2
E. -3/2
F. -3
Answer:
A
Step-by-step explanation:
calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 6, - 6) and (x₂, y₂ ) = (6, 0) ← 2 points on the line
m = [tex]\frac{0-(-6)}{6-(-6)}[/tex]= [tex]\frac{0+6}{6+6}[/tex] = [tex]\frac{6}{12}[/tex] = [tex]\frac{1}{2}[/tex]

Gracie walks around the edge of a circular lake exactly 15 times. If she walks 2178 m in total, what is the diameter of the lake? If your answer is a decimal, give it to 1 d.p.
The diameter of the lake is 6.2 m.
What is the diameter?The diameter is the distance from one edge of the circle to the next across the center.
The diameter can be determined given the circumference and pi, since circumference is pi x diameter.
The number of times Gracie walks around the circular lake = 15 times
The total distance covered by the walk = 2,178 meters
The circumference (the distance around the edge of the circular lake) is 145.2 m (2,178 ÷ 15).
Circumference = C = 2πr = πd
Diameter = C/π
145.2 ÷ 3.143
= 46.2 m

Find the value of x in each triangle
Answer:b 40
A60
Step-by-step explanation:
Answer:
Step-by-step explanation:
so for figure a:
we can find x by using sin which is sin = opposite/hypotenuse so
- sin30= x/10cm(sin30 is equivalent to 1/2 or 0.5)
- 0.5= x/10cm or 1/2=x/10cm (i'm gonna use the 2nd option)
- 10cm * 1/2=x
-x=5cm
and for figure b:
here we also use sin
- sin 50= x/8cm (sin 50 is equivalent to 0.7660 )
- 0.7660= x/ 8cm
-0.7660 * 8cm=x
- x= 6.128cm and when estimated x= 6cm
