The formula for an exponential decay problem is: y = x (1 - r)^x
Where x = initial amount, r = rate of decay and x = # time periods
So, x = $258, r = 8% = .08 and x = 11 years
y = 258 (1 - 0.08)^11 = 258 (0.92)^11 = 258 * 0.3996 = $103.10

Michael runs a distance of 5 1/4 miles in 45 3/4 minutes during a fade. At this rate, what is Michaels average speed in miles per hour?
Answers
Answer: Micheal's average Speed =6.885 miles per hour
Step-by-step explanation:
Speed= Distance /time
Given the distance he ran as = 5 1/4 miles
And Time taken = 45 3/4 minutes
changing to hours becomes
60 mins = 1 hour
45 3/ 4 mins = 45 3/4 mins/ 60mins x 1hour
= 45.75 /60 = 0.7625hours
Therefore Micheal's average Speed= Distance /time
=5 1/4miles / 0.7625hours = 5.25/ 0.7625
=6.885 miles per hour
approximately 7 miles/hour.

Ok, so all we have to do is multiply 8 * 3/4, because each child needs 3/4 of the sandwich, and there are 8 of them. The easiest (My opinion) way to do this is by turning 8 into a fraction. Turning whole numbers into fractions is really simple, just slap a /1 under them to make them a fraction. And so, our fraction is 8/1. Now, all we have to do is multiply the top part of the fraction, and then the bottom part of the fraction. So, 8 * 3 = 24, and 1 * 4 = 4. So, just put 24/4 as an answer. But, wait! We have to simplify it! 24 divided by 4 is 6, so 6 is our final answer.

Melinda takes readings of the depth of water in a
pond every day for 1 week. Here are her results in
meters:
6.5, 6.8, 7.2, 6.8, 6.6, 6.3, 6.4
What are the mean, median, and mode water levels
for the week, rounded to the nearest tenth?
Answer with supporting work:
Answers
Answer:
a) The Mean of the water levels for the week (μ) = 6.657
b) The Median of the water levels for the week = 6.6
c) Mode = 6.8
Step-by-step explanation:
Step(i):-
Given that the data per one week
6.5, 6.8 , 7.2 ,6.8 ,6.6 ,6.3 , 6.4
we have to find the mean of the given data
Solution:-
Mean = ∑x /n
[tex]Mean = \frac{6.5+6.8+7.2+6.8+6.6+6.3+6.4}{7}[/tex]
Mean = [tex]\frac{46.6}{7}[/tex]
Mean(μ) = 6.657
The Mean of the water levels for the week (μ) = 6.657
Step(ii):-
Given that the data per one week
6.5, 6.8 , 7.2 ,6.8 ,6.6 ,6.3 , 6.4
we have to find the Median of the given data
A median is the center value of a given data when arranged in an order
6.3 6.4 6.5 6.6 6.8 6.8 7.2
The Median = middle of the given data
The Median = 6.6
Step(iii):-
Given that the data per one week
6.5, 6.8 , 7.2 ,6.8 ,6.6 ,6.3 , 6.4
we have to find the Mode of the given data
Mode = Value repeated the most number of times
The value 6.8 repeated two times
∴ Mode = 6.8
A fair 10 sided die rolled until a 7 is first seen. What is the probability of rolling the die six times?
Answers
Answer:
The probability of rolling a dice six time until a 7 is first seen is 0.059
Step-by-step explanation:
The probability of getting a seven is equal to [tex]\frac{1}{10}[/tex]
The dice need to be rolled only six times.
This means that for the first 5 times the dice showed values other than 7 and in the last roll it displays 7
Hence the probability of rolling a dice six time until a 7 is first seen is
[tex](\frac{9}{10})^5 * (\frac{1}{10})^1[/tex]
[tex]= \frac{9^5}{10^6} \\= 5.90[/tex] % or 0.059
Last year Emily invested some money and had gained 8% profit and her friend, Samira invested some money and gained 9% profit. Their total profit on the two investments was $1720. This year they each decided to invest the same amount of money as last year. Emily gained 7% profit this year and Samira gained 6%. If they receive a total profit of $1280, how much money did Emily invest? Answer.
Answers
Answer:
Emily's investment = $8,000
Step-by-step explanation:
Let Emily's invested amount = x
Let Samira's amount = y
8% of Emily's amount = 8/100 × x = 0.08x
9% of Samira's amount = 9/100 of y = 0.09y
∴ 0.08x + 0.09y = 1720
multiplying through by 100
8x + 9y = 172000 - - - - - (1)
7% of Emily's amount = 0.07x
6% 0f Samira's amount = 0.06y
0.07x + 0.06x = 1280
multiplying through by 100
7x + 6y = 128000 - - - - - - (2)
Next, let us subtract eqn 2 from eqn 1
equation (1) - equation 2
8x + 9y = 172000
-
7x + 6y = 128000
= x + 3y = 44000 - - - - (3)
from eqn (3) x = 44000 - 3y - - - - - (4)
putting this value of x into eqn 1
8x + 9y = 172000
8 (44000 - 3y) + 9y = 172000
352000 - 24y + 9y = 172000
-15y = 172000 - 352000 = -180000
y = 180000 ÷ 15
y = $12,000
finding x using eqn (4)
x = 44000 - 3y
x = 44000 - 3(12000)
x = 44000 - 36000
x = $8,000
∴ Emily's investment = $8,000
50,60,72 find the 8th term airthmetic and geometric sequence
Answers
Answer:
8th term is 179.15904
Step-by-step explanation:
The sequence is geometric with a common ration = 6/5
r = 60/50 = 72/60 = 6/5
Use the formula
[tex]a_{n} = ar^{n - 1}[/tex]
In your case a = 50, r = 6/5 and n = 8
[tex]a_{8} = 50(6/5)^{8 - 1} \\ = 50(6/5)^{7} \\ = 50(279936/78125)\\ = 179.15904[/tex]
