A programmer for a weather website needs to display the proportion of days with freezing temperatures in a given month.
Their algorithm will operate on a list of temperatures for each day in the month. It must keep track of how many temperatures are below or equal to 32. Once it's done processing the list, it must display the ratio of freezing days over total days.
Which of these correctly expresses that algorithm in pseudocode?
The correctly expresses that algorithm in pseudocode
numFreezing ← 0
numDays ← 0
FOR EACH temp IN temps
IF (temp ≤ 32)
{numFreezing ← numFreezing + 1}
{numDays ← numDays + 1}
DISPLAY(nonfreezing/numDays)
For this situation, Pseudocode B would be appropriate. Two variables are created by this code for the overall number of days (numDays) and the number of freezing days (nonfreezing). Then, it does a loop over the complete collection of data to determine whether each temperature is less than or equal to 32 degrees.
If so, it adds it to nonfreezing; otherwise, it skips the step while still increasing the number of days after each loop by 1. Contrary to answer A, which prints the ratio after each loop iteration, this answer only prints the ratio once the loop has been completed.
numFreezing ← 0

The only graph that has a function referred to as many-to-one function is; Graph A
How to Identify Graph Functions?A many-to-one function is defined as a function that have y-values associated to more than one x-value.
Graphically speaking, if a horizontal line is drawn through the graph, such horizontal line would cross the graph at least twice.
In the graphs, we can see that A is a parabola, and that if a horizontal line is drawn above y = 0, the line will go through the parabola twice. For example, in y = 10 it will cross the parabola at the point (-3, 10) and (3, 10). Therefore, this is a many-to-one graph.
The second graph is a one-to-one graph since there is only one y-value associated to each x-value.
The third graph is not even a function because by definition of function, each element of x should be associated with ONE element of y. In this case, x= 5 and x = 9 are associated to more than one y elements (the vertical lines that form two sides of the square) and therefore is not a function.

express the distance between the given numbers using absolute value. then find the distance by evaluating the absolute value expression. 3 and 18
The distance between the points 3 and 18 is expressed as |3 - 18| and the absolute value of the expression is 15 units.
We are given two numbers 3 and 18 and we are asked to determine the distance between these two points using absolute value.
The distance between two numbers is equal to their difference and distance is always a positive quantity so the absolute value function is used over the distance to prevent a negative distance. The distance between points x and y is given by |x - y|
Put 3 and 18 in |x - y|
|x - y| = |3 - 18| = |-15|
The absolute value function is defined by |x| = x if x ≥ 0 or -x if x < 0
Here, -15 < 0. It can be concluded that |-15| = -(-15) = 15
The distance between the points 3 and 18 is expressed as |3 - 18| and the value of the expression is 15 units.

There are more than 1/4 million species of beetle. Assume the average length of a beetle is 1 cm and the average walking speed is 10 cm per second. These beetles walk up a gang-plank that is 5 meters long onto an ark. They do this in pairs, side by side, one male and one female from each species. The pairs of beetles are spaced so there is a gap of 7 cm between species. How many hours will it take for all 1/4 million species of beetles to embark onto the ark once the first pair starts up the gangplank?
It will take a total of 41.68 hours for 1/4 million species of beetles to embark.
How many species will embark?A total of 250,000 species will embark (1,000,000/ 4 = 250,000)
How long will it take them to embark?Each pair of beetles will occupy 6 cm (one centimeter + space before the next pair). This means the space for all the beetles is 1500000 cm (250000*6 cm)
Now, their speed is 10 cm/per second, so at this speed, it will take 150000 seconds to pass the bottom of the gang-plank (1500000/ 10) + 50 seconds to go up, which is equal to 150050 seconds. Based on this, let´s find out the time

(β) between B and C:
Reliability of B and C functioning together = Probability of both B and C functioning properly = 0.7 * 0.8 = 0.56
(γ) between A and C:
Reliability of A and C functioning together = Probability of both A and C functioning properly = 0.6 * 0.8 = 0.48
Note: The calculations are based on the assumption that the components function independently and the failure of one component does not affect the functioning of another component.

What is the percent of change from 400 to 600?
The percent of change from 400 to 600 is 33.34%.
What is Percentage Increase?
The final increase in quantity is expressed as a percentage by the term "percentage increase". A quantity's growth from its starting value to its final value through time is compared using the percentage increase formula. The final value minus the initial value, divided by the initial value, and multiplied by 100 are how this formula is mathematically expressed.The formula for percentage increase is given as, [tex]\% \text Increase = \frac{\text FV - IV}{FV} \times 100[/tex], where FV is the Final Value and IV is the Initial Value.It is given that the percent of change is from 400 to 600.
There is an increase from 400 to 600, so the percent of change is an increase.
[tex]\% \text Increase = \frac{\text FV - IV}{FV} \times 100[/tex]
Here, the final value (FV) = 600 and initial value (IV) = 400.
Substituting the given values in the above formula, we get
[tex]\% \text Increase = \frac{600-400}{600} \times 100\\\implies \% \text Increase = \frac{200}{600} \times 100\\\implies \% \text Increase = 33.34 \%[/tex]

Parallel: y = -3x + 2.
Perpendicular: y = x/3 - 4/3.
What is the point-slope form?Mathematically, the point-slope form of a line is modeled by this mathematical expression:
y - y₁ = m(x - x₁)
Where:
m represents the slope.x and y are the points.In order to determine the point of intersection of the lines, we would use an online graphing calculator to graph the given system of equations, and this is given by the ordered pair (1, -1).
Additionally, the slope of the given equation 3x + 4y = 0 in standard form is equal to -3. In Geometry, two (2) lines are parallel under the following conditions:
m₁ = m₂ (m represents the slope.)
At data point (1, -1), an equation of this parallel line can be calculated in point-slope form as follows:
y - y₁ = m(x - x₁)
y - (-1) = -3(x - 1)
y = -3x + 3 - 1
y = -3x + 2.
In Mathematics, a condition that must be met for two lines to be perpendicular is given by:
m₁ × m₂ = -1
-3 × m₂ = -1
m₂ = 1/3
At data point (1, -1), an equation of this perpendicular line in point-slope form is:
y - y₁ = m(x - x₁)
y - (-1) = 1/3(x - 1)
y = x/3 - 1/3 - 1

human visual inspection of solder joints on printed circuit boards can be very subjective. part of the problem stems from the numerous types of solder defects (e.g., pad non-wetting, knee visibility, voids) and even the degree to which a joint possesses one or more of these defects. consequently, even highly trained inspectors can disagree on the disposition of a particular joint. in one batch of 10,000 joints, inspector a found 734 that were judged defective, inspector b found 742 such joints, and 954 of the joints were judged defective by at least one of the inspectors. suppose that one of the 10,000 joints is randomly selected. a.

i. Inspector A
ii. Inspector B
iii. Inspector A or B
iv. Inspector A and B
b. What is the probability that the selected joint was judged to be defective by neither of the two inspectors?
c. What is the probability that the selected joint was judged to be defective by inspector B but not by inspect
The probability that the selected joint was judged to be defective by inspector B but not by inspector A is 0.0695.
A. i. The probability that the selected joint was judged to be defective by Inspector A is 734/10000 = 0.0734.
ii. The probability that the selected joint was judged to be defective by Inspector B is 742/10000 = 0.0742.
iii. The probability that the selected joint was judged to be defective by Inspector A or B is 954/10000 = 0.0954.
iv. The probability that the selected joint was judged to be defective by both Inspectors A and B is the intersection of their judgments, which can be found by subtracting the defective joints found only by one inspector from the total defective joints found by both inspectors. The probability is (954 - (734 - 742))/10000 = 0.0478.
B. The probability that the selected joint was judged to be defective by neither of the two inspectors is (10000 - 954)/10000 = 0.9046.
C. The probability that the selected joint was judged to be defective by Inspector B but not by Inspector A is 742 - 0.0478 = 695/10000 = 0.0695.
