A randomly generated password contains four characters. Each of the four characters is either a lowercase letter or a digit from 0–9. Each character in the password cannot be used more than once.
What is the approximate probability that exactly one of the four characters will be a number?
1%
11%
28%
44%
The approximate probability that exactly one of the four characters will be a number is 44% option fourth is correct.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
We have:
A randomly generated password contains four characters. Each of the four characters is either a lowercase letter or a digit from 0–9.
Total letters = 26
Total numbers = 10
Total = 10 + 26 = 36
Total possibilities = 36×35×34×33 = 1413720
Password with one number = C(10, 1) = 10
With three letters = C(26, 3) = = 2600
Outcomes = 2600×10 = 26000
Favorable outcomes = 26000×4! = 624000
Probability = 624000/1413720 = 0.44 = 44%
Thus, the approximate probability that exactly one of the four characters will be a number is 44% option fourth is correct.

-9-11x=68 Steps please
We can start this equation off by doing the inverse operation for each sides. We add 9 to both sides in order to get rid of the -9 term to get:
[tex]-11x = 77[/tex]
We now divide both sides by -11 in order to "isolate" our x variable to get:
[tex]x = -7[/tex]
Answer:
x=-7
Step-by-step explanation:
-11x=68+9
-11x=77
divide both sides by -11
x=-7

A bee flies at 6 feet per second directly to a flowerbed from its hive the bee stays at the flowerbed for 17 minutes, and then flies directly back to the hive at 4 feet per second. It is away from the hive for a total of 22 mins
Answer:
576 feet.
Step-by-step explanation:
5 - 13 = 2 minutes x 60 =120 seconds that the bee spent flying back and forth.
a - Distance = Time x Speed
Time =Distance / Speed
D / 12 + D / 8 = 120, solve for D
b - D = 576 feet from the hive to the flowerbed.

If a certain cannon is fired from a height of 9.8 meters above the ground, at a certain angle, the height of the cannonball above the ground, h, in meters, at time, t, in seconds, is found by the function h(t) = -4.9t² + 30.5t +9.8. Find the time it takes for the cannonball to strike the ground.
Answer:
6.53 s
Step-by-step explanation:
The height of the cannon ball is represented by a quadratic function as:
h(t) = -4.9t² + 30.5t +9.8.
At 0 s (i.e. t = 0), h(0) = -4.9(0²) + 30.5(0) + 9.8 = 9.8
That means that the cannon ball is initially at a height of 9.8 m above the ground. To calculate the time it takes the ball to touch the ground, we use:
h(t) = -4.9t² + 30.5t +9.8
It touches the ground when h(t) = 0. Hence:
0 = -4.9t² + 30.5t + 9.8
Solving the above quadratic equation gives:
t = 6.53 s and t = -0.31 s
Since the time cannot be negative, hence t = 6.53 s. Therefore it takes the ball 6.53 s to hit the ground.
Kim’s family invested $3000 in a certificate of deposit (CD) for her when she was born. the interest rate is 8% and is compounded quarterly. what is the value of the CD in 5 years? what is the value of the CD if it is compounded annually for 15 years?
Answer:Kim’s family invested $3000
Step-by-step explanation:
The value of the CD will be an amount of $7487.01 if it is compounded annually for 15 years.
What is Compound interest?Compound interest is defined as interest paid on the original principal and the interest earned on the interest of the principal.
To find the value of the CD in 5 years, you need to calculate the compound interest earned over 5 years.
The interest rate is 8% per year, so the interest rate per quarter is 8% / 4 = 2%.
The value of the CD at the end of each quarter can be calculated using the formula:
CD value at end of quarter = CD value x (1 + interest rate per quarter)
For example, at the end of the first quarter, the CD value would be:
CD value at end of first quarter = $3000 x (1 + 0.02) = $3060
You can repeat this process for each quarter to find the CD value at the end of 5 years.
After 5 years, there will have been 20 quarters (5 years x 4 quarters per year), so the CD value at the end of 5 years will be:
CD value at end of 5 years = $3000 x (1 + 0.02)²⁰ = $4393.84
To find the value of the CD if it is compounded annually for 15 years, you can use the same formula, but use the annual interest rate of 8% and the number of years of 15. The CD value at the end of 15 years will be:
CD value at end of 15 years = $3000 x (1 + 0.08)¹⁵ = $7487.01
