A dice game pays a player $5 for rolling a3 ot a 5 with a single die. the player has to pay $2 for any other roll. if a person plays the game 30 times, what is the approximate probability ttrat the person will win at least $15?
Answers
The approximate probability that the person will win at least $15 is 0.255.
To solve this problem, we need to calculate the probability of winning at least $15 after playing the game 30 times. Winning at least $15 means that the player must win on at least 6 rolls because winning once pays $5, and $5 times 6 is $30, which is the minimum needed to have a net gain of $15 ($30 won - $15 lost).
First, let's calculate the probability of winning in a single roll. The player wins if they roll a 3 or a 5, which are two favorable outcomes out of six possible outcomes.
[tex]\[ P(\text{win on a single roll}) = \frac{2}{6} = \frac{1}{3} \][/tex]
The probability of losing in a single roll is the complement of the probability of winning:
[tex][ P(\text{lose on a single roll}) = 1 - P(\text{win on a single roll}) = 1 - \frac{1}{3} = \frac{2}{3} \][/tex]
Now, we need to find the probability of winning at least 6 times in 30 rolls. This can be modeled using the binomial probability formula:
[tex]\[ P(X = k) = \binom{n}{k} p^k (1-p)^{n-k} \][/tex]
where [tex]\( n \)[/tex] is the number of trials (30 in this case), [tex]\( k \)[/tex] is the number of successes (at least 6), [tex]\( p \)[/tex] is the probability of success on a single trial [tex](\( \frac{1}{3} \)), and \( \binom{n}{k} \)[/tex] is the binomial coefficient.
We want to calculate the probability of winning at least 6 times, which is the sum of the probabilities of winning exactly 6, 7, .. up to 30 times:
[tex]\[ P(X \geq 6) = \sum_{k=6}^{30} \binom{30}{k} \left(\frac{1}{3}\right)^k \left(\frac{2}{3}\right)^{30-k} \][/tex]
[tex]\[ P(X \geq 6) \approx 0.255 \][/tex]
for the dilation, Do, k = (10, 0 ) —> (5,0) , the scale factor is equal to ____.
•-5
•5
•0.5
•2
Answers
Answer:
•0.5
Step-by-step explanation:
We'll assume the dilation was done at the origin point, so it was done evenly.
Since the k point went from (10,0) to (5,0), we know it was reduced... so the scale factor has to be below 1. A scale factor means the size wasn't changed and a dilation/scale factor larger than 1 means it was enlarged.
So, we take the new X-value (5) and divide it by the original X-value (10).
Scale factor = 5/10 = 1/2... so 0.5

Answers
Answer:
the first function, y = (x + 1)^2, does pass through the points (1, 4), (2, 9), and (3, 16).
Step-by-step explanation:
Note that 4, 9 and 16 are squares of 2, 3 and 4. So it's likely that the parent function is of the form f(x) = x^2. Note that f(1) = 1, f(2) = 4, f(3) = 9 and f(4) = 16.
Let's now determine whether these three points satisfy the first given equation, y = (x + 1)^2: Does 4 = (1 + 1)^2? Does 4 = 2^2? YES.
Does 9 = (2 + 1)^2? Does 9 = 3^2? YES
Does 16 = (3 + 1)^2? YES
So the first function, y = (x + 1)^2, does pass through the points (1, 4), (2, 9), and (3, 16).
Final answer:
The detailed answers cover questions related to functions, sequences, equations of lines, slopes, and graphing lines.

The length of a rectangle is 3 meters more than the width. The perimeter of the rectangle is 26 meters. If the width is b, which equation represents the situation? How many solutions will this equation have?
Answers
Answer:
Thehe answer is 75
Step-by-step explanation:
Answer with Step-by-step explanation:
The length of a rectangle is 3 meters more than the width.
If the width is b.
⇒ Length=b+3
The perimeter of the rectangle is 26 meters.
Since, Perimeter=2(Length+width)
⇒ 2(b+3+b)=26
dividing both sides by 2
⇒ b+3+b=13
⇒ 2b=13-3
⇒ 2b=10
dividing both sides by 2
⇒ b=5
⇒ Width=5 meter
and Length=5+3=8 meter

Answers
Answer:
$3735
Step-by-step explanation:
The formula for simple interest is I = Prt, where I is the interest earned, P is the initial investment, r is the interest rate in decimal form, and t is the time in years. We have everything we need to find the interest, which is the amount your investment earned while it sat there for 7 years. Once we find that interest amount, we will add it to the intial investment to find the total amount after 7 years that your money has grown to.
I = 3000(.035)(7) so
I = 735
3000 + 735 = 3735
Answer:
$3,630
Step-by-step explanation:
You invest $3,000 in an account at 3.5% per year simple interest.
We have to calculate the amount in the account at the beginning of the 7th year. This means we have to calculate the interest for completed 6 years.
Formula for simple interest
A = P(1+rt)
A = Amount after maturity
P = Principal amount ( 3,000)
r = rate of interest in decimal ( 0.035)
t = time in years ( 6 )
Now we put the values in to formula
A = 3,000(1 + 0.035 × 6)
A = 3,000 ( 1 + 0.021 )
A = 3,000 × 1.21
A = $3,630
The amount would be $3,630 at the beginning of the 7th year.

Answers
Answer:
D
Step-by-step explanation:
Let the following point represent the first job: (4, $144). Let (6, $188) represent the second. Then we find the equation of the line through these two points. As we go from (4, $144) to (6, $188), x increases by 2 and y increases by $44. Thus, the slope of this line is m = rise/run = $44/(2 hrs), or $22/hr.
Using the slope-intercept formula for a straight line, y = mx + b, we find the equation of this line by finding the y-intercept, b:
Subbing the given info ($22/hr for m, 4 hr for x and $144 for y), we get:
$144 = ($22/hr)(4 hr) + b, or
$144 = $88 + b, which yields b = $56.
Thus, the desired equation is y = mx + b, or y = ($22/hr)x + $56. This matches the last answer (D)

A survey showed that hamburgers are preferred to hot dogs 5 to 3. What percent of those surveyed prefer hamburgers
Answers
Final answer:
62.5% of those surveyed prefer hamburgers.
Explanation:
The question is asking to find the percentage of people who prefer hamburgers over hot dogs when given the ratio of 5 to 3.
To calculate this, you would add the two parts of the ratio together to get the total number of parts, which is 5 + 3 = 8.
The number of parts that represent hamburgers is 5.
To find the percentage, you would divide the hamburger part by the total number of parts and then multiply by 100.
This gives you (5/8) × 100, which equals 62.5%.
Therefore, 62.5% of those surveyed prefer hamburgers.
Ms.Holmes decided to water her plants.She had 2 1/2 gallons of water.She gave each plant 1/4 gallon of water.Which expression could be used to determine how many plants Ms.Holmes had?
Answers
To determine how many plants Ms. Holmes had, divide the total amount of water she had by the amount of water she gave each plant. The expression that can be used is (2 1/2 gallons) divided by (1/4 gallon per plant). Simplifying the expression gives the answer of 10 plants.
Explanation:To determine how many plants Ms. Holmes had, we can divide the total amount of water she had (2 1/2 gallons) by the amount of water she gave each plant (1/4 gallon per plant).
So, the expression that can be used is (2 ½ gallons) ÷ (1/4 gallon per plant). To divide a fraction by a fraction, we multiply the first fraction by the reciprocal of the second fraction. Therefore, the expression simplifies to (2 ½ gallons) × (4 gallons per plant).
Simplifying further, we get 10 gallons. This means that Ms. Holmes had 10 plants.

A diagram can be a useful aid to answering this question. At one corner of the shed, 8 ft of rope is no longer available, so the quarter circle has a radius of 18-8 = 10 ft. (That side of the shed is 12 ft, so the area is only a quarter circle.)
At the other corner of the shed, 12 ft of rope is no longer available, so the quarter circle has a radius of 18-12 = 6 ft. (That side of the shed is 8 ft, so the area is only a quarter circle.)
In the attached diagram, the 3/4 circle with radius 18 ft is shown red, and the quarter circles are shown in green.

Given that g(x)=3x^2 -4x+3, find each of the following.
PICTURE DOWN BELOW!!!
Answers
Answer:
see explanation
Step-by-step explanation:
To evaluate the expression for the given values.
Substitute the given values for x into g(x)
a
g(0) = 3(0)² - 4(0) + 3 = 0 - 0 + 3 = 3
b
g(- 1) = 3(- 1)² - 4(- 1) + 3 = 3 + 4 + 3 = 10
c
g(2) = 3(2)² - 4(2) + 3 = 12 - 8 + 3 = 7
d
g(- x) = 3(- x)² - 4(- x) + 3 = 3x² + 4x + 3
e
g(1 - t)
= 3(1 - t)² - 4(1 - t) + 3
= 3(1 - 2t + t²) - 4 + 4t + 3
= 3 - 6t + 3t² - 4 + 4t + 3
= 3t² - 2t + 2
A fair coin is tossed 3 times. What is the probability that the coin with land showing heads on all three tosses.

Answer:2/3
Step-by-step explanation:
Answer:
1/8
Step-by-step explanation:
one way we can solve this is by making a tree using H for heads and T for tails
since it can land H or T, we put them down like this. then we can get H or T again because its a coin, so we put that under each letter. finally we do the same thing again to get 8 possibilities. now we can count how many of them was HHH, which is one
H T
/ \ / \
H T H T
/\ /\ /\ /\
H T H T H T H T
^ this one
or do 2 x 2 x 2 because there are 2 possibilities each three times
