If A, B, and C are nxn invertible matrices, does the equation C^-1(A+X)B^-1=In have a solution, X? if so, find it
If A, B, and C are nxn invertible matrices, the equation C^-1(A+X)B^-1=I(n) has a solution which is X=CB-A. Since invertible matrices are those whose inverse matrix exists.
For A to be the matrix here A⁻¹ is the inverse of it, so AA⁻¹=I, here I is the identity matrix ,since the matrix equation given to us is: C⁻¹(A+X)B⁻¹=In, now multiplying B on the right side and C on the left side we get :CC⁻¹(A+X)B⁻¹B=CIₙB
=>Iₙ(A+X)Iₙ=CIₙB
=>A+X=CB, according to the property of the identity matrix.Now adding -A on both sides we get,
=>A+X+(-A)=CB+(-A)
=>X=CB-A, so here the solution for the given matrix equation is: X=CB-A

The weight of an organ in adult males has aâ bell-shaped distribution with a mean of 330 grams and a standard deviation of 15 grams. Use the empirical rule to determine the following. â(a) About 68â% of organs will be between whatâ weights? â(b) What percentage of organs weighs between 285 grams and 375 âgrams? â(c) What percentage of organs weighs less than 285 grams or more than 375 âgrams? â(d) What percentage of organs weighs between 300 grams and 375 âgr
The empirical rule states that in a normal distribution, 68% of the observations lie within 1 standard deviation from the mean, 95% of the observations lie within 2 standard deviations from the mean, and , 99.7% of the observations lie within 3 standard deviations from the mean.
a) - Mean = U = 330 grams
standard deviation= [tex]\sigma=40 \: grams[/tex]
As per the empirical rule, 68% of the observations lie within 1 standard deviation from the mean.
Let [tex]X_1[/tex] and [tex]X_2[/tex] be the 2 random value, between which 68% of the observations lie.
Mathematically,
[tex]X1=U-\sigma[/tex]
[tex]X1[/tex] = 330 - 40
[tex]X1[/tex] = 290
Similarly,
[tex]X1=U-\sigma[/tex]
[tex]X1[/tex] = 330 + 40
[tex]X1[/tex] = 370
Thus, about 68 % of organs will be between 290 and 370 grams in weight.
b) - In this, we need to find the percentage of organs weighing between 250 grams and 410 grams.
We can rewrite 250 as follows:
250= 330− 80 ⇒ 30−2(40) ⇒ 330−2(σ)
The above value (250) lies within 2 standard deviations from the mean.
Similarly,
We can rewrite 410 as follows:
410 = 330+80 ⇒ 330+2(40) ⇒ 330+2(σ)
The above value (410) lies within 2 standard deviations from the mean.\
As per the empirical rule, 95% of the observations lie within 2 standard deviations from the mean.
Thus, 95% of organs weighs between 250 grams and 410 grams.
c)-As we have calculated in part(b) that 95% of the organs lie within 250 and 410 grams.
So, area outside these values = Total area under curve - 95%
= 100 - 95 ⇒ 5%
So, 5% of the area lies outside the 250 and 410 grams range.
From the property of normal curve, we know that the area under the curve is divided into 2 equal parts.So, we divide the area- 5% into 2 equal parts which gives 2.5%.

How to form two-way table?Suppose two dimensions are there, viz X and Y. Some values of X are there as X_1, X_2, ... , X_n and some values of Y are there as Y_1, Y_2, ... , Y_n
List them in title of the rows and left to the columns. There will be n \times k table of values will be formed(excluding titles and totals), such that:
Value(ith row, jth column) = Frequency for intersection of X_i and Y_j (assuming X values are going in rows, and Y values are listed in columns).
Then totals for rows, columns, and whole table are written on bottom and right margin of the final table.
For n = 2, and k = 2, the table would look like:
[tex]\begin{array}{cccc}&Y_1&Y_2&\rm Total\\X_1&n(X_1 \cap Y_1)&n(X_1\cap Y_2)&n(X_1)\\X_2&n(X_2 \cap Y_1)&n(X_2 \cap Y_2)&n(X_2)\\\rm Total & n(Y_1) & n(Y_2) & S \end{array}[/tex]
where S denotes total of totals, also called total frequency.
n is showing the frequency of the bracketed quantity, and intersection sign in between is showing occurrence of both the categories together.
We are given that;
Males Females Total
Soccer | 31 | 50 | 81
Basketball | 21 | 50 | 71
Total | 52 | 100 | 152
Now,
A. More males were surveyed than females.
True. From the table, we can see that 52 males were surveyed, while only 100 females were surveyed.
B. More females like soccer.
False. From the table, we can see that 31 males and 50 females like soccer, so a total of 81 people like soccer. This is the same as the number of females surveyed, so we cannot say that more females like soccer.
C. An equal number of people like soccer and basketball.
False. From the table, we can see that 81 people like soccer, while 71 people like basketball.
D. Twice as many females than males like basketball.
False. From the table, we can see that 21 males and 50 females like basketball. Twice the number of females who like basketball is 100, which is the total number of females surveyed, but this is not twice the number of males who like basketball.
Therefore, by the two-way table the answer will be more males were surveyed than females.

Each day the zucchini grew by the same amount as the day before plus another 3 inches. On which day would the zucchini be longer than 11 fest? Show all worke
The Zucchini will be longer than 11 feet on the ninth day.
How did the plant grow?Since 12 inches is equal to 1 foot, then 11 feet will be equal to 132 inches. Below, we are going to describe the rate of the plant's growth from day 1.
Day 1 = 6 inches
Day 2 = 6 + 9 inches = 15 inches
Day 3 = 15 + 9 + 3 = 27 inches
Day 4 = 27 + 12 + 3 = 42
Day 5 = 42 +15 + 3 = 60
Day 6 = 60 + 18 + 3 = 81
Day 7 = 81 + 21 + 3 = 105
Day 8 = 105 + 24 + 3 = 132
Day 9 = 132 + 27 + 3 = 162
We are told that on the second day, the tree grew up to 15 inches and subsequently, it grew by the same amount as the day before plus another three inches.
Going by that calculation, on the third day, the tree will grow by 9 inches plus three more inches and this continues. Finally, on the ninth day, the tree would have grown up to 162 inches which is greater than 132 inches or 11 feet.

7. You want to survey the people at the local pool about the food
served in the snack shack. You decide to walk around the kiddy
pool and survey parents. Is this a random sample? Why or why not?
In the research effort where a researcher want to survey the people at the local pool about the food served in the snack shack by deciding to walk around the kiddy pool and survey parents, this is an example of random sample because every parent in the pool have equal chance of being chosen for the study.
What does a random sample mean at first?A random sample is drawn at random from the entire population to represent the entire data set, with each member having an equal chance of being chosen. Researchers can generate a random sample by employing techniques such as lotteries or random draws.
Because the data set is chosen using random selection, every member of the population has an equal chance of being chosen.

a. Make a table of values for the number of
rounds and the number of teams participating.
b. What is the reasonable domain and the range
of this function? Explain.
c. Find the rate of decay.
d. Find the decay factor.
a. Here's a table of values for the number of rounds and the number of teams participating:
Round Number of Teams
1 16
2 8
3 4
4 2
5 1 (Champion)
.b. domain: [1 5]
Range: {1 16]
C. Rate of decay = 8
D. Decay factor = 0.5
How to solve for the rate of decayb. The reasonable domain of this function would be the number of rounds, and the range would be the number of teams participating in each round.
The domain would be all positive integers from 1 to the maximum number of rounds,
The range would be all positive integers from 1 to the starting number of teams (16 in this case).
c. To find the rate of decay, we can calculate the ratio of the change in the number of teams to the change in the number of rounds.
Using Round 1 to Round 2,
= (16 - 8) / (2 - 1)
= 8.
d. The decay factor is the ratio of the number of teams in a given round to the number of teams in the previous round.
Using Round 1 to Round 2, the decay factor is
= 8 / 16
= 0.5
