Answer:
y = -3x + 13
Step-by-step explanation:
Assuming the line is linear, you can use the point-slope equation of a line.
(y - y) = m (x - x)
The y and x variables come from the points on the line. Points are written in the form (x, y). In the point (2,7), 2 is x and 7 is y.
1. Plug your points in.
(7 - - 2) = m (2 - 5)
2. Solve for m (the slope)
(7 + 2) = m (2 - 5)
(9) = m (-3)
9 = -3m
m = -3
3. Write an equation of the line with the slope you found.
You can write this equation in different forms, but I'll use the slope-intercept form.
y = mx + b
You'll have to find b, the y-intercept. You can plug one of your points in for x and y as well as your slope, m, and solve for b.
7 = -3(2) + b
7 = -6 + b
b = 13
Therefore, the equation is y = -3x + 13
where in the world would you expect to have a relative humidity of close to 100%? what about close to 0%?
100% humidity is very common in many coastal zones, near rivers or lakes or in your bathroom when you take a shower, and possibly in Alaska as well as UAE.
Relative humidity:
Relative humidity is the ratio of the current absolute humidity to the highest possible absolute humidity (which depends on the current air temperature). A reading of 100 % relative humidity means that the air is totally saturated with water vapor and cannot hold any more, creating the possibility of rain. This doesn't mean that the relative humidity must be 100 percent in order for it to rain — it must be 100 percent where the clouds are forming, but the relative humidity near the ground could be much less.
0% humidity means there is an absence of water vapor in the air.

A satellite dish has a parabolic cross section and is 10 feet deep. The focus is 4 feet from the vertex. Find the width of the satellite dish at the opening. Round your answer to the nearest foot
The width of the satellite dish at the opening is 23 feet.
To find the width of the satellite dish at the opening, we need to use the formula for the cross section of a parabola, which is y^2 = 4px, where p is the distance from the vertex to the focus. In this case, p = 4 and y = 5 (half the depth of the dish). We can solve for x by plugging in these values and solving for y:
25 = 4(4)x
x = 25/16
Since we need to find the width at the opening, we need to double this value to account for both sides of the dish:
2x = 25/8
To round to the nearest foot, we need to find the nearest whole number. Since 25/8 is between 3 and 4, we round up to 4, giving us a width of 23 feet.

There are four activities on the critical path, and the standard deviations for their durations are 5, 12, 34, and 16 days. The standard deviation of the duration of the critical path is:
a. 67
b. 16.75
c. 8.185
d. 1581
e. 39.76
The standard deviation of the duration of the critical path is (e) 39.76.
To calculate the standard deviation of the duration of the critical path, we need to consider the activities on the critical path and their corresponding standard deviations.
The standard deviation of the critical path can be found using the following formula:
Standard deviation of the critical path = Square root of the sum of the variances of the activities on the critical path
Given the standard deviations of the activities on the critical path are 5, 12, 34, and 16 days, we can calculate the variances as the square of the standard deviations:
Variance of activity 1 = 5² = 25
Variance of activity 2 = 12² = 144
Variance of activity 3 = 34² = 1156
Variance of activity 4 = 16² = 256
Now we can find the sum of the variances:
Sum of variances = 25 + 144 + 1156 + 256 = 1581
Finally, we take the square root of the sum of variances to get the standard deviation of the critical path:
Standard deviation of the critical path = √1581 ≈ 39.76
Therefore, the correct answer is e) 39.76.

Which of the following sets of numbers could represent the three sides of a triangle? {6,8,14} {13,20,34} {11,14,22} {13,20,35}
The set of numbers {6, 8, 14} and the set {11, 14, 22} could represent the three sides of a triangle.
To determine whether a set of numbers could represent the sides of a triangle, we need to check if it satisfies the triangle inequality theorem. According to the theorem, the sum of any two sides of a triangle must be greater than the length of the third side.
Let's evaluate each set of numbers:
1. {6, 8, 14}
The sum of the two smaller sides is 6 + 8 = 14, which is greater than the third side 14. Therefore, this set could represent the sides of a triangle.
2. {13, 20, 34}
The sum of the two smaller sides is 13 + 20 = 33, which is less than the third side 34. Hence, this set cannot represent the sides of a triangle.
3. {11, 14, 22}
The sum of the two smaller sides is 11 + 14 = 25, which is greater than the third side 22. Therefore, this set could represent the sides of a triangle.
4. {13, 20, 35}
The sum of the two smaller sides is 13 + 20 = 33, which is less than the third side 35. Hence, this set cannot represent the sides of a triangle.
In summary, the sets {6, 8, 14} and {11, 14, 22} could represent the three sides of a triangle.

Assume that a real estate investor that rents for $2,000 per month. Which payment plan would the nvestor prefer for the current 12-month lease? payment of $2,000 at the first of each month upfront payment of $24,000 payment of $2,000 at the end of each month payment upfront of $12,000 and $12,000 half-way through the lease
To determine which payment plan the real estate investor would prefer, we need to compare the present value of each payment option. Assuming a discount rate of 0%, meaning no time value of money is considered, we can directly compare the payment amounts.
1. Payment of $2,000 at the first of each month: This results in a total payment of $24,000 over the 12-month lease.
2. Upfront payment of $24,000: This option requires paying the full amount at the beginning of the lease.
3. Payment of $2,000 at the end of each month: Similar to option 1, this results in a total payment of $24,000 over the 12-month lease.
4. Upfront payment of $12,000 and $12,000 half-way through the lease: This option requires paying $12,000 at the beginning of the lease and another $12,000 halfway through the lease.
Since all the payment options have a total cost of $24,000, the real estate investor would likely prefer the payment plan that offers more flexibility or matches their cash flow preferences. Options 1 and 3 provide the investor with the option to pay monthly, while options 2 and 4 require a larger upfront payment. The choice would depend on the investor's financial situation and preferences.

say a certain manufacturing industry has 63.1 thosand jobs in 2008,but is
The manufacturing industry is expected to experience a 27% decline in job count from 2008 to 2018.
What will be the percent change in the manufacturing industry's job count?To calculate the percent change, we need to find the difference between the job count in 2008 and 2018, and then divide it by the job count in 2008. The formula is:
Given:
Job count in 2008 = 63.1 thousand jobs
Average annual decline = 1.7 thousand jobs per year
Number of years = 2018 - 2008 = 10
Job count in 2018 = Job count in 2008 - (Average annual decline * Number of years)
= 63.1 - (1.7 * 10)
= 63.1 - 17
= 46.1 thousand jobs
Percent Change = ((Job count in 2018 - Job count in 2008) / Job count in 2008) * 100
= ((46.1 - 63.1) / 63.1) * 100
= (-17 / 63.1) * 100
= -0.27 * 100

The closest answer is 80 cupcakes per minute, so the correct option is .8. The closest answer is 165 minutes, so the correct option is 165.
The throughput capacity of the icing stage can be calculated by dividing the number of cupcakes in a batch (100) by the time required to process each cupcake (1.25 minutes).
Throughput capacity = Number of cupcakes in a batch / Time to process each cupcake
Throughput capacity = 100 cupcakes / 1.25 minutes
Throughput capacity = 80 cupcakes per minute
The closest answer is 80 cupcakes per minute, so the correct option is .8.
The throughput time for a batch of cupcakes is the time required to process the entire batch, including the setup time.
Throughput time = Time for setup + (Number of cupcakes in a batch * Time to process each cupcake)
Throughput time = 40 minutes + (100 cupcakes * 1.25 minutes per cupcake)
Throughput time = 40 minutes + 125 minutes
Throughput time = 165 minutes
The closest answer is 165 minutes, so the correct option is 165.
