A computer password contains six characters but does not permit repetition of any characters (either letters or numbers). If uppercase and lowercase letters are used, how many possible passwords are there?
Answer:
[tex]\frac{62!}{56!}[/tex]
Step-by-step explanation:
We can either look at all 62 characters (2 * 26 in the alphabet and 10 digits), choose 6 of them, and add the fact that we care about their order - so multiply by 6! and we get [tex]\binom{62}{6}\cdot 6! = \frac{62!}{6!\cdot 56!} \cdot 6! = \frac{62!}{56!}[/tex]
Or, we can look atr all the permutations of all the characters and take into account that we DON'T care about the order of the 56 after the first six. Getting [tex]\frac{62!}{56!}[/tex] immediately.

Two people share proceeds of a business venture in the ratio 2:3 If the proceeds came to GHS 2,350,000 how much does each get?
Answer:
GHS 940,000 and GHS 1,410,000
Step-by-step explanation:
Total Ratio, thus 2+3 = 5 = 2,350,000
2/5 × 2,350,000 = 940,000
3/5 × 2,350,000 = 1,410,000
In conclusion, the money was shared at GHS 940,000 and GHS 1,410,000 among the two.
During a sale of computers, one-fourth of
the inventory was sold the first day. The next
day two-thirds of the remaining inventory was
sold. What percent of the total inventory was
sold during the second day?
Answer:
On the second day, 50% of the total computer inventory was sold.
Step-by-step explanation:
Since during a sale of computers, one-fourth of the inventory was sold the first day, while the next day two-thirds of the remaining inventory was sold, to determine what percent of the total inventory was sold during the second day, we must perform the following calculations:
1/4 = 0.25 = 25%
Remaining = 100 - 25 = 75%
75/3 = 25 x 2 = 50
Thus, on the second day, 50% of the total computer inventory was sold.
The rate of healing, A′(t)(in square centimeters per day), for a certain type of abrasive skin wound is given approximately by the table.
t 0 1 2 3
A′(t) 0.91 0.83 0.76 0.69
t 4 5 6 7
A′(t) 0.62 0.58 0.48 0.44
Use left and right sums over five equal subintervals to approximate the area under the graph of A′(t) from t=0 to t=5.
The left sum, L5, is __________.
The right sum, R5, is ______________.
Answer:
Step-by-step explanation:
Given that:
t 0 1 2 3 4 5 6 7
A'(t) 0.91 0.83 0.76 0.69 0.62 0.58 0.48 0.44
a) [tex]\Delta x = \dfrac{5-0}{5}[/tex]
[tex]\Delta x = 1[/tex]
[tex]L_ 5= \Delta x ( (A'(0)+A'(1)+A'(2)+A'(3)+A'(4)) \\ \\ = 1 (0.91 + 0.83+ 0.76 +0.69 + 0.62 ) \\\\ L_5 =1( 3.81) \\ \\ \mathbf{L_5 = 3.81}[/tex]
[tex]R_ 5= \Delta x ( (A'(1)+A'(2)+A'(3)+A'(4)+A'(5)) \\ \\ = 1 ( 0.83+ 0.76 +0.69 + 0.62 +0.58) \\\\ R_5 =1( 3.48) \\ \\ \mathbf{R_5 = 3.48}[/tex]
The true statement:
[tex]Since, R_5 = 3.48 \ and \ L_5 = 3.81; \\ \\ Then : R_5 \le \int \limits ^5_0 A'(t) dt \le L_5[/tex]
a painter is paid by the hour if he is paid 360 for 12 hours work how much will he be paid for 9 hours work
Answer: $270
Step-by-step explanation:
1. calculate how much he's getting paid per hour
- 360 / 12 = $30
2. calculate how much he's getting paid for 9 hours
- 30 * 9 = $270
The amount he would be paid for 9 hours of work is 270.
How much would the painter be paid for 9 hours of work?The first step is to determin1 be how much the painter would be paid for 1 hour of work.
Pay for working for 1 hour = 360 / 12 = 30
The pay for 9 hours = 30 x 9 = 270
Ted jogged a total of 11.2 miles in 4 days. He jogged the same distance each day
Part A
How far did he jog each day? Enter your answer in the box,
2.8
milos
00:00
Part B
How many total miles would Ted jog if he continued to jog the same number of miles each day for 6 days? Enter your answer in the box
Answer:
Part A: 2.8 miles
Part B: 16.8 miles
Step-by-step explanation:
First, solve for how many miles Ted jogged in 1 day:
Variable x = number of miles
11.2/4 = x/1
Cross multiply
11.2 × 1 = 4 × x
11.2 = 4x
Divide both sides by 4
2.8 = x
He jogged 2.8 miles every day.
To find how many miles Ted would jog in 6 days, simply multiply his miles per day by the number of days he will jog:
2.8 miles × 6 days = 16.8 miles in 6 days

find the value of" A" such that triangle DEF with vertices D (a,1) , E(10,7) and F(7 ,11) is a right angle at E?
a=2
Answer:
(m1) slope of DE=(7-1)/(10-a)=6/(10-a)
(m2) slope of EF=(11-7)/(7-10)=4/-3=-4/3
since line are perpendicular
m1m2=-1
6/(10-a) ×-4/3=-1
6/(10-a)=3/4
6×4=3(10-a)
24=30-3a
3a=30-24
a=6/3=2
According to genetic theory, the blossom color in the second generation of a certain cross of sweet peas should be red or white in a 3:1 ratio. That is, each plant has probability 3/4 of having red blossoms, and the blossom colors of separate plants are independent. Using the Binomial distribution, what is the exact probability that more than 7 out of 10 these plants have red blossoms
Answer:
The answer is "0.250".
Step-by-step explanation:
Given:
[tex]P(X=7) \\\\ n=10\\\\ p=0.75\\\\x \sim Binomial (n = 10, p = 0.75)\\[/tex]
[tex]P(X=7) =\binom{n}{x} P^{x} (1-p)^{(n-x)} \\\\[/tex]
[tex]= \binom{10}{7}(0.75)^7(1-0.75)^{10-7} \\\\=120 \times (0.75)^7 \times (0.25)^3\\\\=0.250[/tex]

9514 1404 393
Answer:
-21, 13
Step-by-step explanation:
If Z is located to the right of Y, its point on the number line is -4+17 = 13.
If Z is located to the left of Y, its point on the number line is -4-17 = -21.
There are two possible locations for Z on a number line.
_____
In a 2-dimensional plane, there are an infinite number of locations of distance 17 from a given point. The set of all of them makes a circle on the plane, with radius 17.
In 3-dimensions, the set of points becomes a sphere with radius 17.

The area of a square is 1800 in2, how long is each diagonal?
9514 1404 393
Answer:
60 in
Step-by-step explanation:
The area of a square can be computed as ...
A = (1/2)d^2 . . . . where d is the length of the diagonal
For an area of 1800 in^2, the diagonal length can be found as ...
1800 in^2 = 1/2d^2
3600 in^2 = d^2
d = √3600 in = 60 in
The length of each diagonal is 60 inches.

What is algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
The number 4,250 is ten times smaller than what number.
let the number be x.
So, x/10 = 4250
Now, make x as subject formula
