The function that represents the amount of radioactive substance left after {x} hours is : f(x)=100(0.15)ˣ.

Given is that the amount of a certain radioactive substance decreases by 15% every hour. A sample starts with 100 g of this radioactive substance.

The function that represents the amount of radioactive substance left after {x} hours is -

f(x)=100(0.15)ˣ

Therefore, the function that represents the amount of radioactive substance left after {x} hours is : f(x)=100(0.15)ˣ.

Answer: width = 4m, perimeter = 26m

Step-by-step explanation:

area of rectangle = width x length

9x = 36

x = 4

width = 4m

perimeter:

9 + 9 +4+4 = 26 m

First known equation is:

2L + 2W = 46

Second equation is:

L = W +7

Put the variable L of the second equation in the first equation.

2(W+7) + 2W = 46

2W +14 +2W = 46

4W = 32

W=8

Then resolve L using any of the above initial equations

L = 8 + 7 = 15

Verify: 2L +2W = 46

2(15) + 2(8) = 30 + 16 = 46 = perimeter

Step-by-step explanation:

Let the length = 7x

Let the breadth = x

As we know that

perimeter of rectangle =2(l+b)

Also perimeter here = 78 inches

Acc. to question

2(l+b) = 78 inches

\(2(7x + x) = 78\)

\(16x = 78\)

\(x = \frac{78}{16} \)

\(x = 4.8\)

so bredth = 4.8 approx

length = 7*4.5 =31.5 approx

Answer:

Solution:

Hi! To solve this inequality, all we should do is multiply both sides by 12:

\(\implies\sf{\dfrac{m}{12} \geqslant3}\\\implies\sf{m\geqslant36}\)

The probability of observing the experiment result, a sample mean, for example, or something more unusual just by chance if the null hypothesis is true is the definition of "P-Value."

A null hypothesis is a sort of statistical hypothesis which asserts that there is no statistical significance in a particular set of observations.

Using sample data, hypothesis testing is performed to determine the believability of a theory. It really is expressed as H0 and is also known to simply as "null."

a) The Corresponding minimum UGPA = 3.70

b) The range of middle 50% values will be: (3.28, 3.52).

A measure of how many standard deviations below or above the population mean a raw score is called z score. It will be positive if the value lies above the mean and negative if it lies below the mean. It is also known as standard score. It indicates how many standard deviations an entity is, from the mean. In order to use a z-score, the mean μ and also the population standard deviation σ should be known. A z score helps to calculate the probability of a score occurring within a standard normal distribution. It also enables us to compare two scores that are from different samples.

a) z score corresponding to top 5% area = 1.645

Hence, Corresponding minimum UGPA = 3.40 + 1.645*0.18 = 3.70

b) z score corresponding to middle 50% area = -0.67, 0.67

Hence, The range of middle 50% values will be:

(3.40 - 0.67*0.18, 3.40 + 0.67*0.18)

The population median commute time of the employees of Asons is 40 minutes.

The median is a measure of central tendency that represents the middle value in a dataset when the data is arranged in ascending or descending order. In this case, the commute times provided are 47.4, 45, 35, and 40 minutes.

To determine the median, we arrange the commute times in ascending order: 35, 40, 45, 47.4. Since there are four values in the dataset, the middle value is the average of the two central values, which are 40 and 45. Taking the average of these two values gives us the median of 40 minutes.

Therefore, the population median commute time of the employees of Asons is 40 minutes, indicating that half of the employees have a commute time of 40 minutes or less, while the other half have a commute time of 40 minutes or more.

Answer:

Step-by-step explanation:

In the given triangle AED, segments GB and FC are parallel to base ED. Points G and F are on segment AE in that order. Lengths AG=2, GF=5, FE=3, GB=6, and CD=7 are given. You want the lengths of AB, BC, FC, and ED.

Segments of transversals crossed by parallel lines are proportional:

  AG : GF : FE = AB : BC : CD

  2 : 5 : 3 = AB : BC : 7

Multiplying the first ratios by 2 1/3 will give the second ratios:

  2 : 5 : 3 = 4 2/3 : 11 2/3 : 7

This lets us conclude ...

  AB = 4 2/3

  BC = 11 2/3

Corresponding segments of similar triangles are proportional:

  AG : GB = FA : FC = AE : ED

  2 : 6 = (5+2) : FC = (5+2+3) : ED

We notice the second number in the first ratio is 3 times the first number. That means these ratios are ...

  2 : 6 = 7 : 21 = 10 : 30

This lets us conclude ...

  FC = 21

  ED = 30

The lengths of the missing sides are calculated to be

The parallel lines in the figure created similarity between the dimensions, this makes the ratio of the dimensions equal

The given dimensions that is used to find the missing sides

Solving for AB

AB / CD = AG / FE

AB / 7 = 2 / 3

cross multiplying

3 * AB = 7 * 2

AB = 14/3 = 4.667

Using AB, GF is calculated

AB / BC = AG / GF

14/3 / BC = 2 / 5

cross multiplying

BC = (5 * 14/3) / 2

BC = 35/3 = 11.667

Solving for FC

GB / FC = AG / A'F

6 / FC = 2 / (2 + 5)

cross multiplying

2 * FC = 6 * 7

FC = 42/2 = 21

Solving for ED

GB / ED = AG / AE

6 / ED = 2 / (2 + 5 + 3)

cross multiplying

2 * ED = 6 * 10

ED = 60/2 = 30

Given the function g(x)=x'e^k where k is a constant and we are to find the value of k for which the function g has a critical point at x=2/3.

The derivative of g(x) will be as follows;g'(x)=ke^k x^(e-1)Therefore,g'(2/3)=ke^k (2/3)^(e-1)For the critical point to exist, g'(2/3) should be equal to zero.

Therefore, we have;ke^k (2/3)^(e-1) = 0Or k = 0 (since (2/3)^(e-1) cannot be zero)Therefore, the value of k for which g has a critical point at x=2/3 is k=0.Hopefully, this helps you.

The two theoretical quantities of ANOVA (Analysis of Variance) are:
1. Between-group variance.

2. Within-group variance:

1. Between-group variance.

This is the variance that can be attributed to differences between the group means.

It is calculated by comparing the mean of each group to the overall mean of all the data points.

The larger the between-group variance, the more likely there are significant differences between the groups.
2. Within-group variance:

This is the variance that can be attributed to differences within each group, i.e., the individual differences among the data points in each group.

It is calculated by comparing the individual data points in each group to their respective group mean.

The smaller the within-group variance, the more likely the groups are homogeneous.
In ANOVA, these two quantities are compared using an F-ratio.

If the between-group variance is significantly larger than the within-group variance, it indicates that there are significant differences between the group means, and the null hypothesis can be rejected.
