If I buy 24 tickets for 25 cents each how much money did I spend?
- The four-digit number 1210 has an interesting property.
The first digit, 1, counts how many zeros are in the number.
The second digit, 2, counts how many ones are in the number.
The third digit, 1, counts how many twos are in the number.
The fourth digit, 0, counts how many threes are in the number.
Another number with this property is 2020 (2 zeros, 2 twos, no ones or threes.) Now,
make a 7 digit number ABCDEFG so that its first digit, A, counts the number of zeros
in the number, the second digit, B, counts the number of ones, and so on down to G,
which counts the number of sixes in the number
Answer:
ABCDEFG = 3211000
Step-by-step explanation:
A counts the number of zeroes, and there are 3 zeroes (E, F, G), so A = 3.B counts the number of ones, and there are 2 ones (C, D), so B = 2.C counts the number of twos, and there is 1 two (B), so C = 1.D counts the number of threes, and there is 1 three (A), so D = 1.There is no four, five, six in, so E, F, G are all zeroes.

At a movie theater, the manager announces that a free ticket will be given to the first person in line whose birthday is the same as someone in line who has already bought a ticket. You have the option of getting in line at any time. Assuming that you don't know anyone else's birthday, and that birthdays are uniformly distributed throughout a 365-day year, what position in line gives you the best chance of being the first duplicate birthday?
please explain how you got this answer. Thank you!
The best chance is an illustration of probability
The 21st position in line gives you the best chance of being the first duplicate birthday
How to determine the best position?
Assume you are in the nth position, the probability of getting a free ticket is:
P(n) = P'(first n - 1 people share a birthday) * P(birthday with first n -1 people)
Mathematically, the above can be represented as:
P(n) = [365/365 * 364/365 * 363/365 * ... * (365 - (n -2))/365] * [(n -1)/365]
Such that: n [tex]\le[/tex] 365
When simplified, the equation becomes
p(n)/p(n+1) = 365/(366 - n) * (n - 1)/n
Where
p(n)/p(n+1) > 1
So, we have:
365/(366 - n) * (n - 1)/n > 1
Evaluate the product
(365n -365)/(366n - n²) > 1
Cross multiply
365n -365 > 366n - n²
Collect like terms
n² + 365n - 366n - 365 > 0
Evaluate the difference
n² - n - 365 > 0
Solve for n using a graphing calculator;
n > - 18.6 or n >19.6
n cannot be negative.
So, we have:
n > 19.6
Approximate to nearest integer
n > 20
The least integer value of n is:
n = 21
Hence, the 21st position in line gives you the best chance of being the first duplicate birthday

When the stick hits the ground it has the height of zero.
Substitute h with 0 and solve the given equation for t:

Answer:
radius = 9.5 cm
Step-by-step explanation:
If 2 chords intersect then the product of the parts of 1 chord is equal to the product of the parts of the other chord, that is
PT × TQ = ST × TR
PT × 3 = 4 × 12 = 48
3 PT = 48 ( divide both sides by 3 )
PT = 16
then
diameter = PT + TQ = 16 + 3 = 19 cm
radius = 19 ÷ 2 = 9.5 cm

======================================================
Explanation:
SA = surface area of the sphere
SA = 4*pi*r^2
SA = 4*pi*8^2
SA = 804.247719
The surface area is roughly 804.247719 sq ft.
I used the calculator's stored version of pi to get the most accuracy possible.
Since 1 paint can covers 75 sq ft, divide that surface area over 75 to find out how many cans you need.
804.247719/75 = 10.72330292
Round up to the nearest integer to get 11
You'll have leftover paint, but it's better to go over the goal than come up short.

Step-by-step explanation:
The sine of an angle is equal to the cosine of its complement. In a right triangle, the acute angles are complementary, which means ...
sin(A) = cos(B)
The two quantities are equal.
Answer:
Step-by-step explanation:
Sin(A) = opposite / hypotenuse
opposite = 4
hypotenuse = 5
Sin(A) = 4/5 = 0.8
Cos(B) = adjacent / hypotenuse.
adjacent = 4
hypotenuse = 5
Cos(B) = 4/5 = 0.8
Believe it or not, this will always happen if you take Sin(A) and find that Cos(90 - A) are equal
Take a simpler case. Suppose you are working with a 30 60 90 triangle.
Cos(60) = Sin(90 - 60) = 1/2

In Theresa's first 8 basketball games, she scored 7,4,3,6,8,3,1 and 5 points. In her
ninth game, she scored fewer than 10 points and her points-per-game average for the nine
games was an integer. In her tenth game, she scored fewer than 10 points and her points-per-
game average for the ten games was an integer. What is the product of the number of points
she scored in the ninth and tenth games?
Answer: 40
Step-by-step explanation: The total number of points from the first 8 games is 7+4+3+6+8+3+1+5=37.
We have to make this a multiple of 9 by scoring less than 10 points.
The closest multiple of 9 is 45. 45-37=8.
Now we have to add a number to get a multiple of 10.
The next multiple is 50 we added 5, multiplying these together you get 8 x 5 is 40.

If f(x) is an exponential function where f(3.5)=21 and f(6.5)=69, then find the value of f(9), to the nearest hundredth.
Answer:
i think the answer is 144
Step-by-step explanation:
ohhh so first we should try finding the slope here. since we know the points are (3.5 , 21) and (6.5, 69) we can use the formula to look for the slope
the formula is:
y2 - y1 / x2 - x1
lets substitute
69 - 21 / 6.5 - 3.5
48 / 3
16
f(x) = 16x + b
now we just substitute
btw i dont think we need to find b because this inst a linear equation? im not sure but yea i dont think we need to find the y-intercept
so anyways
f(9) = 16(9)
= 144
