5× - 3y - z =1
× + 4y - 6z = -1
2× + 3y + 4z =9
The solution to the system of equations, using elimination, is given as follows:
x = 0.0135, y = -0.2767, z = -0.1024.
How to obtain the solution to the system of equations?The solution to the system of equations is obtained using the elimination method, as the variables are written as functions of each other and then solved.
The system in this problem is composed by the equations presented as follows:
5x - 3y - z = 1.x + 4y - 6z = -1.2x + 3y + 4z = 9.From the first equation, the variable z is written as function of variables x and y, as follows:
z = 5x - 3y - 1.
Replacing in the second equation, we have that:
x + 4y - 6(5x - 3y - 1) = -1
-29x + 22y = -7.
Replacing in the third equation, we have that:
2x + 3y + 4(5x - 3y - 1) = -1
22x - 9y = 3.
Hence the system is now:
-29x + 22y = -7.22x - 9y = 3.Multiplying the first equation by 9 and the second by 22, we have that:
-261x + 198y = -63.484x - 198y = 66.Adding the equations, the solution for x is obtained as follows:
223x = 3
x = 3/223
x = 0.0135.
Then the solution for y is obtained as follows:
-261(0.0315) + 198y = -63
y = (-63 + 261(0.0315))/198
y = -0.2767.
The solution for z is:
z = 5(0.0135) - 3(-0.2767) - 1 = -0.1024,

based on information from a large insurance company, 68% of all damage liability claims are made by single people under the age of 25. a random sample of 52 claims showed that 41 were made by single people under the age of 25. does this indicate that the insurance claims of single people under the age of 25 is higher than the national percent reported by the large insurance company? give the test statistic and your conclusion.
Yes, it indicates that the number of single people under the age of 25 is higher than the national percentage reported by the large insurance company, according to the calculated z-score.
here the sample size is = 25(n), therefore sample proportion will be, p⁰= 41/25 =0.774 .since the null hypothesis is :H₀:p =0.68 and the alternative hypothesis is :H₁:p>0.68 .The z-test is :
Z=p⁰−p/ √(p(1-p)/n
= 0.774-0.68/root(0.68(1-0.68)/52
=1.453
The p-value for the z score = 1.453 is 0.0731.Here the P-value is greater than the 5% level of significance. We come up short to dismiss the null hypothesis at the 5% level of significance. it can be concluded that the number of single individuals under the age of 25 is higher than the national percentage detailed by the large insurance company.

in a survey, 24 people were asked how much they spent on their child's last birthday gift. the results were roughly bell-shaped with a mean of $35 and standard deviation of $15. construct a confidence interval at a 90% confidence level.
The confidence interval at a 90% is 29.533 ≤ μ ≤ 40.467
Given that
mean = 35
standard deviation = 15
We compute the confidence interval as follows:
μ =¯ˣ± ME
Where:
μ = is the population mean,¯x = 35 is the sample mean and,ME = is the margin of error.To calculate the margin of error, we will use the t-distribution since the sample is very small n<30. Thus, our margin of error will be calculated as:
ME = t ×[tex]\frac{s}{\sqrt{n} }[/tex]
Where:
t = is the t-score at the 90% confidence level
degree of freedom df = 24 -1 =23
s = 15 is the standard deviation and,
n =24 is the sample size.
From the t-distribution tables, we will read the values of t at a critical value [tex]\alpha[/tex] = 0.10, and the degree of freedom is 23. This will give t= 1.714.
Thus, the margin of error is:
ME = 1.714 ×[tex]\frac{15}{\sqrt{23} }[/tex]
ME = 1.714 ×3.19
ME = 5.467
the confidence interval for the population mean is equal to:

The percent change from the old model to the new model estimation of a 5-year old dog's age is 41.66% .
The traditional model involved multiplying the dog's age with seven to calculate their age in human years. for example if the age of dog is 3 years , so in human years he/she will be 3x7 = 21 years old in human years.
Here we calculate the age of 5-years old dog in human years. So we multiply the 5 with 7 and get the answer as 35 years .
As per the new convention 5-years old dos's age is nearly equal to 60 in human years.
So the difference in age in both the methods is
age difference = 60 - 35

3- (pogil) a friend claims that flipping a coin 100 times and finding that it comes up heads only 45% of the time shows that the coin is biased. how should you reply?
with 100 flips, the outcome is very likely to be 45 heads or even less.
just because you have a 50% chance of getting heads, does not necessarily mean that you will get heads at exactly 50%.
100 coin flips will not always produce a 50-50 outcome of heads or tails. This is due to the fact that random events, while predictable in the long run, are not 100% predictable in small cases. For example, if we flipped a fair coin a quadrillion times, the variability in the outcomes caused by the coin's randomness would amount to a fractional value so small that calculators might even round the percentage of heads to 50%. However, with 100 flips, the outcome is very likely to be 45 heads or even less.

In the given situation, the work done by gravity is zero as any work done during a downward part of the motion as undone during the upward parts.
Work refers to the measurement of energy transfer that happens when an object is moved over a distance by an external force which is applied in the direction of the displacement. Hence, the work done is given by the multiplication of force and displacement in the direction of force i.e., W = F x d. As in the given case, the displacement d = 0 as the particle returns to the same point. The work done by gravity would measure the displacement along the y-axis and as the total displacement is zero, hence, work done will be zero.

Given;
The average cost to a 50-year-old male for a $100,000 term life policy is $14. 34 per month. The same policy would cost a 70-year-old male $79. 79 per month.
A 70-year-average old's monthly expense (MAC) is $79.79
A 50-year-average old's monthly expense (MAC) is $14.34
MAC → Monthly Average Cost
To get how much more will the 70-year-old pay for a 20-year term;
We will multiply the monthly value by the yearly and solve the given data,
The extra amount paid = (MAC of 70 years old * 12 - MAC of 50 years old * 12) * 20 years term.
= ($79.79 * 12 - $14.34 * 12) * 20

If the wait() and signal() semaphore operations are not executed atomically, then mutual exclusion may be violated as a wait operation atomically decrements the value associated with a semaphore.
Semaphores refers to integer variables utilized to solve the critical section problem by using two atomic operations, wait and signal that are used for process synchronization. The wait operation decreases the value of its argument S, if it is positive and if S is negative zero or negative, then no operation occurs. The signal operation increases the value of its argument S. Operation wait() and signal() must be completely atomic or else it violates the mutual exclusion. Mutual exclusion refers to the property of process synchronization which asserts that “no two processes can exist in the critical section at any given point of time”.

High school B rented and filled 12 vans and 6 busses with 456 students. Each van and each bus carried the same number of students. Find the number of students in each van and each bus.
7v + 12b = 640
12v + 6b = 456
Multiply the bottom equation by -2 in order to cancel out 12b with 6b.
7v + 12b = 640
- 24v -12b = -912
-17v = -272
17v = 272
v = 272/17
v = 16 students
If we use this: 7v + 12b = 640 ;then:
7(16) +12b = 640
112 +12b = 640
12b = 640 -112
12b = 528
b = 528/12
b = 44 students
So the number of students in each van is 16, and number of students in each bus is 44.
