y/32+16/10
Answer:
y = (-256)/5
Step-by-step explanation:
Solve for y:
y/32 + 8/5 = 0
Put each term in y/32 + 8/5 over the common denominator 160: y/32 + 8/5 = (5 y)/160 + 256/160:
((5 y)/160 + 256/160) = 0
(5 y)/160 + 256/160 = (5 y + 256)/160:
(1/160 (5 y + 256)) = 0
Multiply both sides of (5 y + 256)/160 = 0 by 160:
(160 (5 y + 256))/160 = 160×0
(160 (5 y + 256))/160 = 160/160×(5 y + 256) = 5 y + 256:
(5 y + 256) = 160×0
0×160 = 0:
5 y + 256 = 0
Subtract 256 from both sides:
5 y + (256 - 256) = -256
256 - 256 = 0:
5 y = -256
Divide both sides of 5 y = -256 by 5:
(5 y)/5 = (-256)/5
5/5 = 1:
Answer: y = (-256)/5

Answer: 7
Step-by-step explanation: I got 7. Here's how I got it:
Use the process of elimination. The 2 cannot be divided by 3, because the number (3) we are dividing by, is greater than the primary number (2). If we divided 3 by 2, we would result in a decimal. Then, I took an estimate. I got rid of the 3 because that number would be a low number to divide by 3.
Then I started plugging in numbers:
(6*2) + 5 + 1 + 4 = 22
As we know, 22 is NOT a product of 3.
So, it has to be 7, but I'll prove my answer:
(7*2) + 5 + 1 + 4 = 24
And yes, 24 can be divided by 3 8 times. I hope this helps.
Clarification: I multiply 6 and 7 by 2 because both numbers would go into the 2 boxes.
How do you simplify 125^(2/3)?
The simplest form of expression 125^(2/3) is 25.
This expression can be solved using exponents. Exponent means a quantity, describing the power to which base number is raised. In other words , Exponent refers to the number of times a number is used in a multiplication. The 4 types of exponents are: positive, negative, zero, and rational. Positive exponents tell you how many times to multiply a base by itself.
In order to solve this expression , we use properties of exponents.
Hence , using the property - [tex]x^{m} x^{n} = x^{mn}[/tex]
and rewriting 125 as cube of 5
i.e. [tex]125=5^{3}[/tex]
→ [tex](5^{3})^{2/3}[/tex]
Now , cancelling the 3s
→ [tex]5^{2}[/tex] = 25
Therefore the answer after simplification is 25.

The graph of Stewart's assignment added as an attachment
How to draw the graph of the scenario?From the question, we have the following parameters that can be used in our computation:
Number of assignments = 36
Rate of assignment per day = 4
This means that the equation of the scenario is
Number of assignments remaining = Initial number of assignments - Rate of assignment per day * Number of days
Represent the number of assignments remaining with y and the number of days with x
So, we have the following representation
y = Initial number of assignments - Rate of assignment per day * x
Substitute the known values in the above equation, so, we have the following representation
y = 36 - 4 * x
Evaluate the products
y = 36 - 4x
So, the equation is y = 36 - 4x and the graph is added as an attachment

What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
percentage, a relative value indicating the hundredth parts of any quantity. We must divide the amount by the sum to get the percentage, then multiply the result by 100.
In essence, percentages are fractions with a 100 as the denominator. We place the percent symbol (%) next to the number to indicate that the number is a percentage. For instance, you would have received a 75% grade if you answered 75 of 100 questions correctly on a test (75/100).

queuing system a has a utilization of 80 percent, and queuing system b has a utilization of 90 percent. both have a single server. say the utilization of both systems increases by 5 percent; that is, a increases from 80 percent to 85 percent while b increases from 90 percent to 95 percent. which system is likely to experience the bigger change in the average time in queue?
For queuing system B, the average time in queue ids going to change significantly as a result of increased utilization.
This is because queuing system B is initially heavily loaded and has less capacity to handle more requests. As a result, an increase in utilization can cause a significant increase in average queue latency on system B compared to system A.
Average Queue Time is a measure of the time a customer or request spends being processed by a server. It is affected by several factors such as server load, customer or request arrival rate, and server service rate. As the load on the queuing system increases, it means that the server is being used more frequently and is no longer available to process incoming requests. This will increase the average time in the queue as more requests accumulate and have to wait to be processed. The greater the increase in occupancy, the greater the impact on average latency.

the sum of two nonnegative numbers is 20. find the numbers if (a) the sum of their squares is as large as possible; as small as possible. (b) one number plus the square root of the other is as large as possible; as small as possible.
For both part (a), the two nonnegative numbers, x and y must be 0 and 20 for the sum of their squares to be as large as possible, and 10 and 10 for the sum of their squares to be as small as possible. For part (b), x must be 20 and y should be 0 for largest possible result, whereas for smallest possible result x must be 0 and y should be 20.
What are nonnegative numbers?Nonnegative numbers are numbers which are greater than or equal to zero.
How to calculate the largest and smallest values based on the conditions?For a much straightforward and easy way of solving such questions we can simply use the trial and error method.
For part (a), we can start off by taking both the numbers as 10. The sum of their squares will now be 100. If we take the numbers as 12 and 8, the sum of their squares will be 208. As we can see by increase one of the numbers we get a larger result. Thus, the largest possible values will be 20 and 0, which will give a result of 400. While carrying out this trial and error method we also found out that the minimum result was obtained when both the numbers were 10.
For part (b), a similar approach can be taken. Through trial and error method we observe that 20 + (0)^1/2 gives the largest possible result, whereas 0 + (20)^1/2 gives the smallest possible result.

researchers investigated whether higher chocolate consumption leads to higher body mass in humans. they analyzed the data using chocolate consumption as the explanatory variable and body mass index as the response; a high bmi typically indicates an overweight person. the slope of the fitted regression line was -0.168, with a standard error of 0.046 and a p-value of 0.003. do these results indicate that people who eat more chocolate have a higher bmi?
No, these results indicate that people who eat more chocolate have a lower body mass index (BMI). The negative slope of -0.168 means that as chocolate consumption increases, BMI decreases. The significant p-value of 0.003 indicates that the results are statistically significant and not due to chance.

The monthly cost for 66 minutes of calls will be $15.84.
Monthly cost is the payment or the bill amount that needs to be paid at the end of the month.
The monthly cost (in dollars) of a long-distance phone plan is a linear function of the total calling time (in minutes)
The monthly cost for 45 minutes of calls = $14.40
The monthly cost for 102 minutes = $19.53
The above values can be paired in groups so as to satisfies the coordinates of a linear function
(45,14.40) and (102,19.53)
Finding the slope of the graph using these points
slope, m=Δy/Δx
m=Δy=19.53 - 14.40 = 5.13
Δx=102 - 45 = 57
m = 5.13/57 =0.09
Finding the equation of the linear function using m = 0.09, and point (45,14.40)
m=Δy/Δx
0.09=y-14.40/x-45
0.09(x-45)=y-14.40
0.09x-4.05=y-14.40
0.09x-4.5+14.40=y
y=0.09x + 9.9
So for 66 minutes, the cost will be;
x = 66, y = ?
y=0.09*66 + 9.9
y=5.94+9.9 = $15.84
The monthly cost for 66 minutes of calls is $15.84.
