What is exponential decay?An exponential function's curve is created by a pattern of data called exponential decay, which exhibits higher decreases over time.
The exponential decay function:
Aₙ = A₀(1-r)ˣ, where y = Final amount, A₀ = Initial amount, r = Rate of decay in decimal form, x = Time.
Given:
An element with mass 630 grams decays by 18.8% per minute.
That means, 18.8% = 0.188
Here, we will use the exponential decay function.
Aₙ = A₀(1-r)ˣ, where y = Final amount, A₀ = Initial amount, r = Rate of decay in decimal form, x = Time.
Here,
A₀ = 630 grams
r = 0.188
x = 7 minutes
Substituting the values to the formula,
A₇ = 630(1-0.188)⁷
A₇ = 630(0.812)⁷
A₇ = 630(0.23275134787)
A₇ = 146.633
A₇ = 146.6 grams.
Therefore, element is remaining 146.6 grams.

Answer:
The amount of each ingredient Alicia uses to make oat biscuits are;
440 g of oat, 220 g of butter, and 110 g of syrup
Step-by-step explanation:
9. The question parameters are
The ingredients with which Alicia makes oat biscuit = Syrup, butter, and oat
The ratio of the ingredients with which Alicia makes oat biscuit = 1 : 2 : 4
The quantity of syrup Alicia has = Large amount (Plenty)
The amount of butter she has = 250 g
The amount of oat she has = 440 g
From the given ratio, we have;
The mass of oat Alicia uses is 2 times the mass of butter she uses and 4 times the mass of syrup she uses
When Alicia uses the 440 g of oat, we have;
The amount of butter she will use = 440 g/2 = 220 g
The amount of syrup she will use = 440 g/4 = 110 g
Therefore, Alicia uses the 440 g of oat, 220 g of butter, and 110 g of syrup

A floor 3.2m long and 2.8 m wide is to be covered with square shaped tiles of length 10cm. Find the coast of flooring if the coast tiles is Rs 150 per 100 tile.
Answers
Answer:
1344
Step-by-step explanation:
100cm = 1 m
Convert the dimensions of the floor to cm = Area of a rectangle = length x breadth = 320 x 280 = 89,600m²
Area of a square = length² = 10cm² = 100cm²
Number of tiles that would be needed = area of floor / area of square
89,600cm² / 100cm² = 896
Cost of one tile = rs 150 / 100 = 1.5
Cost of 896 tiles = 1.5 x 896 = 1344

The elephants at the zoo eat 3 2/3 buckets of bananas each day. The zookeeper bought 7 1/3 buckets of bananas. How many days will the bananas last? Write your answer as a fraction or as a whole or mixed number
Answers
Answer: 2 days
Step-by-step explanation:
The monkeys eat 3 ²/₃ buckets of bananas each day. Convert this to an improper fraction:
= 3²/₃ = 11/3 buckets per day
The zookeeper bought 7¹/₃ which is:
= 22/3 buckets
To find out the number of days the bananas will last, divide the buckets bought by the buckets eaten per day:
= 22/3 ÷ 11/3
= 22/3 * 3/11
= 66/33
= 2 days
If dividing fractions, multiply by the reciprocal of the second fraction.

A bank manager wants the average time that a customer waits in line to be at most 3 minutes. Customers at the bank have complained about the long wait times. To test whether the average wait time at the bank is greater than 3 minutes, 60 customers were randomly selected as they entered the bank and their wait times were recorded. The mean wait time was 4.7 minutes. A one-sample t-test resulted in a p-value of 0.00031.Which of the following is an appropriate interpretation of the pp-value?A)The probability that the population mean wait time is greater than 3 minutes is 0.00031.B)The probability that the sample mean wait time is greater than 3 minutes is 0.00031.C)If the population mean wait time is greater than 3 minutes, the probability of observing a sample mean wait time of 4.7 minutes or more is 0.00031.D)If the population mean wait time is 3 minutes, the probability of observing a sample mean wait time of 4.7 minutes is 0.00031.E)If the population mean wait time is 3 minutes, the probability of observing a sample mean wait time of 4.7 minutes or more is 0.00031.
Answers
Answer:
An appropriate interpretation of the p-value is
E) If the population mean wait time is 3 minutes, the probability of observing a sample mean wait time of 4.7 minutes or more is 0.00031
Step-by-step explanation:
A one-sample t-test is used for the comparison between the derived mean of the sample data and the a known mean value, given that the population standard deviation is unknown
The P value indicates the likelihood of obtaining a mean with a value difference from the hypothetical mean which is as much as or more than the difference between the observed mean and the hypothetical
Therefore, an appropriate interpretation of the p-value is if the population mean wait time is 3 minutes then the probability of observing a sample mean wait time of 4.7 minutes or more is 0.00031.
The option E is correct option which is if the population mean wait time is 3 minutes, the probability of observing a sample mean wait time of 4.7 minutes or more is 0.00031.
Given-
For the experiment the total customers were selected is 60.
Mean wait time of the experiment is 4.7 minutes.
T-test result in a p-value is 0.00031.
T-test- this test tell that how significant is the differences between the groups. It means it tell us that if the difference happens by the chance.
The probability that the population mean wait time is greater than 3 minutes is 0.00031-
Now in the given options the option is E is best interpretation of this pp-test. According to option E, the population mean wait time is 3 minutes the probability of observing a sample mean wait time of 4.7 minutes or more is 0.00031.
When the t test is performed it is all about the chances of the groups of the experiment results. The time which is taken by a customer in real will be more than this time and thus the probability of observing a sample mean wait time of 4.7 min or more is 0.00031 as the test data suggest.
Hence the option E is correct option which is if the population mean wait time is 3 minutes, the probability of observing a sample mean wait time of 4.7 minutes or more is 0.00031.

Step-by-step explanation:
divide 30 by 5
you'll get 6
so one-fifth is equivalent to 6 of the pieces
multiply 6 by 2
you'll have 2 so two-fifths is equal to 12 pieces of rice crispy treats
subtract 12 from 30
30 - 12 = 18

Triangle CDF is similar to triangle EGF
(ACDF ~ AEGF). What is the value of x?
A. 15
B.11
C. 9
D. 6
Answers
Answer:
B.11
Step-by-step explanation:
Two triangles are said to be similar if they have the same shape and the ratio of their corresponding sides are in the same proportion.
From the image, CF corresponds to EF, CD corresponds to EG and DF corresponds to GF.
DF = DE + EF = 7 + 5 = 12
Since Triangle CDF is similar to triangle EGF. hence:
[tex]\frac{CF}{EF} =\frac{DF}{GF} \\\\\frac{CF}{5}=\frac{12}{4} \\\\CF=\frac{12*5}{4}\\\\CF=15[/tex]
We can see that:
CF = CG + GF (line segment addition postulate)
CF = x + 4
15 = x + 4
x = 15 - 4
x = 11
