0.079 liters is 79.1 ml with correct significant numbers.
We know that 1 liters = 1000 ml
Hence, 1 ml = 0.001 liters
In the given question we need to convert 79.1 ml to liters. So, we multiply 79.1 ml by 0.001 l to convert ml to liters.
79.1 x 0.001 = 0.0791 l
The given question 79.1 ml has 3 significant figures. Hence, we can write 0.0791 as 0.079 l as 3 significant figures, counting the digits on the right of decimal point.
Therefore, 0.0791 liters is 79.1 ml. On rounding it to correct significant numbers, we get 0.079 l.

Insertion Sort with Binary Search is still a linear time-complexity algorithm in the average and worst case, but it is not the best option for sorting large arrays of elements, as the time complexity remains quadratic.
Insertion Sort is a simple sorting algorithm that works by inserting each element in its correct position in a sorted list.
a. It uses Θ(n²) comparisons in the worst case: This statement is true. In the worst-case scenario, Insertion Sort with Binary Search still takes Θ(n²) comparisons to sort an array of n elements. This happens when the array is sorted in descending order, and the elements need to be inserted one by one at the beginning of the list.
b. It uses Θ(n log n) comparisons in the average case: This statement is false. Insertion Sort with Binary Search still uses Θ(n²) comparisons in the average case, even though the use of Binary Search reduces the number of comparisons compared to Linear Search.
c. It uses Θ(n) comparisons in the best case: This statement is false. In the best-case scenario, Insertion Sort with Binary Search still takes Θ(n²) comparisons, as every element needs to be compared and inserted in its correct position

The baggage handling services of On-Time Airlines is interested in how many baggage handlers they need on duty at various times of the day to ensure that passengers do not wait an unreasonable amount of time for their baggage. An airport executive performed a study and found that there is correlation between the number of passengers arriving at given times and the number of bag handlers needed. She sampled various times during the day and different days of the week including weekends. She recorded the number of passengers arriving within any 1-hour time block. The computer output from the regression equation analysis is shown below.

What is the value of the correlation coefficient for the number of baggage handlers and number of
arriving passengers?
A) -0.842
B) 0.651
C) 0.709
D). .842
E) 1.562
The value of the correlation coefficient for the number of baggage handlers and the number of arriving passengers is 0.842.
Therefore the answer is D. 0.842
The correlation coefficient is a measure of the strength of the linear relationship between two variables. It is a value between -1 and 1, where -1 indicates a perfect negative linear relationship, 1 indicates a perfect positive linear relationship, and 0 indicates no linear relationship.
In this case, the output from the regression equation analysis states that the correlation coefficient is √0.709 = 0.842, which means that there is a strong positive linear relationship between the number of baggage handlers and the number of arriving passengers. A correlation coefficient of 0.842 is considered a strong positive relationship.
In this case, an increase in the number of arriving passengers is associated with an increase in the number of baggage handlers needed, as reflected by the positive correlation coefficient.

Determine the length of the unknown side given: abc ~efg
Answer:
20
Step-by-step explanation:
Given that the triangles are similar, we know that the corresponding side lengths should all have similar ratios.
This means that ab/ef = bc/fg = ca/ge as they're corresponding.
We know that ge = 8, ca = 4, ab = 10 and we want to find ef
Remember ab/ef = ca/ge so 10/ef = 4/8
4/8 = 10/ef
==> cross multiply
80 = 4ef
==> divide both sides by 4
20 = ef
We can test our answer by seeing if the ratios are the same
ab/ef = 4/8 = 1/2
ca/ge = 10/20 = 1/2
The ratios are the same, therefore our answer is correct.

Two equal sides of a triangle are each 4m less than three times the third side. Write down the dimensions of the triangle, if its perimeter is 55m
Answer:
9 m , 23 m , 23 m
Step-by-step explanation:
let the third side be represented by x , then the 2 equal sides are
3x - 4 and 3x - 4
the perimeter (P) is the sum of the 3 sides
P = x + 3x - 4 + 3x - 4 = 7x - 8
given P = 55 m , then equating
7x - 8 = 55 ( add 8 to both sides )
7x = 63 ( divide both sides by 7 )
x = 9
3x - 4 = 3(9) - 4 = 27 - 4 = 23
sides of triangle are 9 m , 23 m and 23 m

ED:AD = 9:6
CB:AB = 15:x
Since we have to multiply the length of ED by 5/3 to get the length of CB, if we multiply the length of AD by 5/3, we can find the length of AB. Since 6*(5/3)=10, the length of AB must be 10.

There is a proportional relationship between hours, x, and number of miles, y, of water in a tank. The point (2, 80) is on a graph of this relationship. Part A: Explain what the point (2, 80) represents. Part B: Write an equation for the relationship in the form of y = mx.
Part A: The point (2, 80) represents that when the number of hours is 2, the number of miles of water in the tank is 80.
Part B: y = 40x
What is the concept of proportional relationships?The theory used in this question is the concept of proportional relationships.
A proportional relationship between two variables is one in which one variable is a constant multiple of the other.
In this case, the number of miles of water in the tank is a constant multiple of the number of hours.
The equation y = mx is used to describe a proportional relation, where m is the constant of proportionality.
The equation for the proportional relationship between hours, x, and number of miles, y, of water in a tank can be written in the form of y = mx. To find the value of m, we can use the point (2, 80) from the graph. We know that when x = 2, y = 80. We can use this information to solve for m.
m = y/x
m = 80/2
m = 40
Therefore, the equation for the proportional relationship is y = 40x.

Probability is a field of mathematics that deals with the study of random events.
In this question, we're looking at the probability of two random numbers having a product greater than 1/2.
