Given two objects represented by the tuples (22, 1, 42, 10) and (20, 0, 36, 8):(a)Compute the Euclidean distance between the two objects. (b) Compute the Manhattan distance between the two objects.
Answer:
(a) 6.708
(b) 11
Step-by-step explanation:
Tuples ( 22, 1, 42, 10) and (20, 0, 36, 8)
Euclidian distance formula
[tex]D = \sqrt{(q1 -p1)^2 + (q2-p1)^2 + (q3 - p3)^2 + (q4 -p4)^2}[/tex]
D = [tex]\sqrt{(22-20)^2 + (1-0)^2 + (42 -36)^2 + (10 -8)^2 }[/tex]
= [tex]\sqrt{(2)^2 + (1)^2 + (6)^2 + (2)^2}[/tex]
= [tex]\sqrt{4 + 1 + 36 + 4 }[/tex]
= [tex]\sqrt{45}[/tex]
D = 6.708
Therefore the Euclidean distance between the tuples is 6.708
Manhattan Distance formula
D = |q1-p1| + |q2 -p2| + |q3 -p3| + |q4-p4|
= |22-20| + | 1-0| + | 42 -36| + | 10-8|
= |2| + |1| + |6| + |2|
D = 11
Therefore the Manhattan distance is equal to 11
5x – 24 > 26
what is the solution to the inequality?
Answer:
x > 10
Step-by-step explanation:
5x - 24 > 26
Add 24 on both sides.
5x -24 + 24 > 26 + 24
5x > 50
Divide by 5 on both sides.
x > 50 ÷ 5
Find x.
x > 10

Step-by-step explanation:
Two dice are rolled; find the probability for total: a) 1, b) 4 or 6; c) <13
Answer:
0 ; 2/9 ; 1
Step-by-step explanation:
In a roll of two dice ;
The sample space = (Number of faces on die)^number of dice rolled = 6^2 = 36
The total possible outcome = sample space = 36
The probability of an event (A) :
P(A) = number of required outcome / number of total possible outcomes
find the probability for total: a) 1,
P(total of 1)
Number of 1 total = 0
Hence, P(total of 1) = 0
b) 4 or 6;
Number of 4 total = 3
Number of 6 total = 5
3 /36 + 5 / 36 = 8/36 = 2/9
c) <13
P(total < 13)
Number of total < 13 = 36
36 / 36 = 1

A card is selected at random from an ordinary deck of 52 cards. What is the probability that it is either an ace or a spade
Answer: 4/13
Step-by-step explanation:
Number of cards in a deck = 52
Number of spades = 13
Number of aces = 4
Number of ace of spade = 1
Probability of either a spade or an ace :
P(spade or ace) = P(spade U ace)
P(spade U ace) = p(spade) + p(ace) - p(spade n ace)
Probability = required outcome / Total possible outcomes
P(spade) = 13 / 52
P(ace) = 4 / 52
P(spade n ace) = 1 / 52
P(spade U ace) = p(spade) + p(ace) - p(spade n ace)
= 13/52 + 4/52 - 1/52
= 16 / 52 = 4 /13

A device produces random 64-bit integers at a rate of one billion per second. After how many years of running is it unavoidable that the device produces an output for the second time? Round to the nearest number of years.
Answer:
3171 × 10^(44) years
Step-by-step explanation:
For each bit, since we are looking how many years of running it is unavoidable that the device produces an output for the second time, the possible integers are from 0 to 9. This is 10 possible integers for each bit.
Thus, total number of possible 64 bit integers = 10^(64) integers
Now, we are told that the device produces random integers at a rate of one billion per second (10^(9) billion per second)
Let's calculate how many it can produce in a year.
1 year = 365 × 24 × 60 × 60 seconds = 31,536,000 seconds
Thus, per year it will produce;
(10^(9) billion per second) × 31,536,000 seconds = 3.1536 × 10^(16)
Thus;
Number of years of running is it unavoidable that the device produces an output for the second time is;
(10^(64))/(3.1536 × 10^(16)) = 3171 × 10^(44) years

A rectangular-shaped parking lot is to have a perimeter of 546 yards. If the width must be 61 yards because of a building code, what will the length need to be?
The length of the parking lot will be 212 yards
Perimeter of rectangleFrom the question, we are to determine what the length of the parking lot needs to be
From the given information, we have that
"A rectangular-shaped parking lot is to have a perimeter of 546 yards"
and
"the width must be 61 yards"
From the formula for perimeter of a rectangle,
P = 2(l +w)
Where P is the perimeter
l is the length
and w is the width
From the given information,
P = 546 yards
w = 61 yards
Putting the parameters into the equation,
546 = 2(l + 61)
546 = 2l + 122
2l = 546 - 122
2l = 424
l = 424/2
l = 212 yards
Hence, the length of the parking lot will be 212 yards

a: f(x)=60x-160
b:f(x)=-60x+160
c:f(x)=-80x +4
d: f(x)= 80x -4
Answer:
The equation that closely represents the graph is [tex]\mathbf{y=60x-160}[/tex]
Option A is correct.
Step-by-step explanation:
We need to find equation that represents the graph.
We can write equation in slope-intercept form: [tex]y=mx+b[/tex] where m is slope and b is y-intercept.
For finding the equation we need to find slope and y-intercept
Finding slope
The slope can be found using formula: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
From the graph we can find [tex]x_1=0, y_1=-160, x_2=1, y_2=-100[/tex]
Putting values and finding slope
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{-100-(-160)}{1-0} \\Slope=\frac{-100+160}{1}\\Slope=-100+160\\Slope=60[/tex]
We get Slope = 60
Finding y-intercept
Using point (0,-160) and slope m = 60, we can find y-intercept
[tex]y=mx+b\\-160=60(0)+b\\b+0=-160\\b=-160[/tex]
Writing the equation
So, the equation for given graph having slope m = 60 and y-intercept b =-160 is:
[tex]y=mx+b\\y=60(x)+(-160)\\y=60x-160[/tex]
So, The equation that closely represents the graph is [tex]\mathbf{y=60x-160}[/tex]
Option A is correct.

Does the rule y = 6x7 represent an exponential function?
yes
no
No , the rule y = 6x ^7 does not represent an exponential function.
The exponential function is a mathematical function of the form f(x) = a^x. where "x" is a variable and "a" is a constant called the base of the function, which must be greater than 0. The exponential function is defined by the formula f(x) = a^x. where the input variable x is displayed as an exponent. An exponential curve depends on the exponential function and the value of x.
We have given y =6 x^7.
Here the variable is base & the exponent is an integer.
But an exponential function has a constant as its base and a variable as its exponent .
So, it does not represent an exponential function .

a) Work out the cost of 100g of each type of tea
b) Which type of tea is the cheapest?
Answer:
The cheapest is the Kenyan tea which costs £1.05 for each 100g.
Step-by-step explanation:
A)
200 g of Kenyan tea costs £2.10
1. Calculate the rate of each gram, by dividing 2.10/200
0.0105 x 100 = £1.05 for each 100g
300 g of Columbian tea costs £3.45
