Answer:
[tex]m=\frac{1}{ab}[/tex]
Step-by-step explanation:
we know that
The formula to calculate the slope between two points is equal to
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
we have the points
(a,1/b) and (b,1/a)
substitute
[tex]m=\frac{1/a-1/b}{b-a}[/tex]
[tex]m=\frac{\frac{b-a}{ab}}{b-a}[/tex]
[tex]m=\frac{1}{ab}[/tex]
The slope of the line joining the points (a,1/b) and (b,1/a) is calculated using the slope formula and is found to be 1 divided by the product of a and b, assuming a and b are not equal and neither is zero.
Explanation:To find the slope of the line joining the points with coordinates (a,1/b) and (b,1/a), we use the slope formula, which is the change in y divided by the change in x. We can write the formula as:
slope (m) = (y2 - y1) / (x2 - x1)
Substituting the given points into the formula gives us:
slope (m) = (1/a - 1/b) / (b - a)
If we assume that a does not equal b and neither a nor b is zero, the slope can be calculated by simplifying the numerator and the denominator:
slope (m) = ((b - a) / (ab)) / (b - a)
The (b - a) terms cancel out, leaving us with:
slope (m) = 1 / (ab)
Therefore, the slope of the line is the reciprocal of the product of a and b.

Step-by-step explanation:
which ordered pair are solutions to this equation? y=2x-3
To find the solutions to the equation y = 2x - 3, substitute different x-values and solve for y.
Explanation:The given equation is y = 2x - 3.
To find the ordered pairs that are solutions to this equation, substitute different x-values and solve for y.
Let's take the first ordered pair (294.5, 61) as an example:
Plug in x = 294.5 into the equation: y = 2(294.5) - 3Simplify: y = 589 - 3 = 586Therefore, the ordered pair (294.5, 61) is not a solution to the equation y = 2x - 3.
Repeat the same process for the other two ordered pairs to determine if they are solutions to the equation.

3 hats and 2 scarves costs £12.
5 hats and 4 scarves costs £21.
Find the cost of a hat.
Find the cost of a scarf.
Answer: Hat: £3 Scarf: £1.50
Step-by-step explanation:
hope this helps
The cost of a hat is £2 and the cost of a scarf is £1.5, obtained by solving the system of simultaneous equations representing the cost relationships.
Explanation:To solve this problem, you need to use a method called simultaneous equations. We denote the cost of a hat as 'h' and the cost of a scarf as 's'.
Then, we write down two equations based on the problem:
3h + 2s = 12 (Equation 1) 5h + 4s = 21 (Equation 2)
From Equation 1, we express 'h' as (12 - 2s) / 3. Substituting this into Equation 2 leaves us with a sole variable 's', after calculating this equation, you obtain s = 1.5, Substituting s into the first equation, we get h = 2. So, the cost of a hat is £2 and the cost of a scarf is £1.5.

What is 24 % 0.4 in mathematics
What is the value of x in the solution to the system
Answer:
whats the equation???
Step-by-step explanation:
Use symbols Replace each with a number to make /24 >1/4 > 4/ a true statement
The numbers that replaces each blank to make the inequality a true statement are 48 and 32. The new inequality is 48/24 > 1/4 > 4/32.
In Mathematics and Euclidean Geometry, an inequality is a relation that compares two or more numbers and variables in an algebraic equation based on any of the following inequality symbols:
Less than or equal to (≤).Greater than (>).Greater than or equal to (≥).Less than (<).Based on the information provided, we can logically deduce the following incomplete inequality;
_/24 > 1/4 > 4/_
In order to make the left-hand side of the inequality true, we must have a number that is greater 1/4 or 0.25;
48/24 = 2
48/24 > 1/4
2 > 0.25 (True)
In order to make the right-hand side of the inequality true, we must have a number that is less than 1/4 or 0.25;
4/32 = 0.125
1/4 > 4/32
0.25 > 0.125 (True).
In conclusion, any number that is greater than 1/4 would make the left-hand side of the inequality true while any number that is less than 1/4 would make the right-hand side of the inequality true.
Complete Question:
Use symbols. Replace each __ with a number to make _/24 >1/4 > 4/_ a true statement.

Jeremy rides his bike at a rate of 15 miles per hour. Below is a table that represents the number of hours and miles Kevin rides. Assume both bikers ride at a constant rate. Which biker rides at a greater speed? Include all of your calculations in your final answer.
Time in hours (x) Distance in miles (y)
1.5 17.25
2 23
3.5 40.25
4 46
The correct answer would be, Jeremy rides at a greater speed than Kevin.
Step-by-step explanation:
Jeremy rides at a rate of 15 miles per hour
Kevin rides at a rate given in the table
Let Y be the distance traveled by Jeremy
And X be the number of hours
Then for Jeremy:
y/x = 15/1
=> y= 15 x
For Kevin:
(46-23)/(4-2)
= 23/2
= 11.5
So for Kevin, Y = 11.5 x
So when Jeremy's and Kevin's rates are compared,
15 > 11.5
which means Jeremy rides at a greater speed.

If the length of the radius of a circle is doubled, how does that affect the circumference and area?
The circumference will be doubled if radius is doubled
The area will increase four times if radius is doubled
Step-by-step explanation:
We will solve the question in two parts.
One for circumference and one for Area
Circumference:
The formula for circumference is given by:
[tex]C = 2\pi r[/tex]
Here r is the radius.
Doubling the radius means that new radius will be 2r
The new circumference will be:
[tex]C_N = 2\pi (2r)\\C_N = 2(2\pi r)\\C_N = 2C[/tex]
Hence,
The circumference will be doubled if radius is doubled
Area:
The area of circle is given by:
[tex]A = \pi r^2[/tex]
Putting radius equal to 2r
[tex]A_N = \pi (2r)^2\\A_N = \pi (4r^2)\\A_N = 4(\pi r^2)\\A_N = 4A[/tex]
Hence,
The area will increase four times if radius is doubled

What is the greatest possible probability in any experiment?
A. 9/10
B. 1
C. 10
D. 100
Answer:
B) GREATEST POSSIBLE PROBABILITY in any experiment is 1.
Step-by-step explanation:
The probability of any event E is given as:
[tex]\textrm{Probability of any event E} = \frac{\textrm{Number of favorable events}}{\textrm{Total Number of outcomes}}[/tex]
Let us assume the the number of TOTAL OUTCOMES of any event E = n
Now, if the event is a SURE EVENT, then all outcomes are favorable events.
So, the total number of maximum favorable events = n
[tex]\textrm{Probability of event E} = \frac{\textrm{Number of favorable events}}{\textrm{Total Number of outcomes}} = \frac{n}{n} = 1[/tex]
Hence, the GREATEST POSSIBLE PROBABILITY in any experiment is 1.

Tuna
What is the experimental probability that the next sandwich sold will be
tuna on wheat bread?
25
23
The experimental probability of the next sandwich sold being tuna on wheat bread is 23 out of 137 sandwiches sold, or approximately 0.168.
Explanation:The problem describes an experimental probability scenario where stopping after having recorded multiple outcomes does not affect the probability of the next outcome. Experimental probability is calculated by taking the number of times an event occurs and dividing it by the total number of trials.
In this case, a total of 137 sandwiches were sold (22 ham on white bread + 24 ham on wheat bread + 21 turkey on white bread + 22 turkey on wheat bread + 25 tuna on white bread + 23 tuna on wheat bread). Out of these, 23 were tuna on wheat bread.
The experimental probability of the next sandwich being a tuna on wheat bread is therefore 23/137, or approximately 0.168, if this same pattern continues.
