What is the greatest common factor of 72 and 34?
Answers
Answer:
2 is GCF
Step-by-step explanation:
The greatest common factor of 72 and 34 is 2
What is greatest common factor ?
GCF means Greatest Common Factor.
By one examples we can understand this concept more easily.
We are taking four numbers 20,50,70,100.
By prime factorisation,
[tex]20 = 2 \times 2 \times 5 \\ 50 = 2 \times 5 \times 5 \\ 70 = 2 \times 5 \times 7 \\ 100 = 2 \times 2 \times 5 \times 5[/tex]
Here greatest common factor of 20,50,70 and 100 is [tex](2 \times 5) = 10[/tex]
So,GCF of 20,50,70 and 100 is 10.
Here numbers are 72 and 34
By prime factorisation,
[tex]72 = 2 \times 2 \times 2 \times 3 \times 3 \\ 34 = 2 \times 17[/tex]
So, greatest common factor of 72 and 34 is 2
So,GCF of 72 and 34 is 2

14 black balls and 6 white balls are placed in an urn. Two balls are then drawn in succession. What is the probability that the second ball drawn is a white ball if the second ball is drawn without replacing the first ball?a) 0.3333
b) 0.2381
c) 0.0952
d) 0.2143
e) 0.3111
Answers
Answer:
[tex]Probability = 0.30[/tex]
Step-by-step explanation:
Given
Represent Black with B and White with W
[tex]B = 14[/tex]
[tex]W = 6[/tex]
Required
Probability of the second selection being white
This means that: The first selection could be white or black but the second must be white.
This probability would be represented as thus:
[tex]Probability = (P(W)\ and\ P(W))\ or\ (P(B)\ and\ P(W))[/tex]
And it is calculated as:
[tex]Probability = (\frac{n(W)}{Total} * \frac{n(W)-1}{Total - 1}) + (\frac{n(B)}{Total} * \frac{n(W)}{Total - 1})[/tex]
Notice that, the second selection has total -1 has its denominator. This is so because, the first selection was made without replacement
So, the formula becomes
[tex]Probability = (\frac{6}{20} * \frac{6-1}{20- 1}) + (\frac{14}{20} * \frac{6}{20- 1})[/tex]
[tex]Probability = (\frac{6}{20} * \frac{5}{19}) + (\frac{14}{20} * \frac{6}{19})[/tex]
[tex]Probability = \frac{30}{380}+ \frac{84}{380}[/tex]
[tex]Probability = \frac{30 + 84}{380}[/tex]
[tex]Probability = \frac{114}{380}[/tex]
[tex]Probability = 0.30[/tex]
The probability that the second ball drawn is a white ball if the second ball is drawn without replacing the first ball is 0.33.
Given :
14 black balls and 6 white balls are placed in an urn. Two balls are then drawn in succession.The formula given below can be used in order to determine the probability that the second ball drawn is a white ball if the second ball is drawn without replacing the first ball.
[tex]\rm P = \left(\dfrac{n(W)}{Total}\times \dfrac{n(W)-1}{Total-1}\right)+ \left(\dfrac{n(B)}{Total}\times \dfrac{n(W)}{Total-1}\right)[/tex]
Now, substitute the values of known terms in the above formula.
[tex]\rm P = \left(\dfrac{6}{20}\times \dfrac{6-1}{20-1}\right)+ \left(\dfrac{14}{20}\times \dfrac{6}{20-1}\right)[/tex]
Simplify the above expression.
[tex]\rm P = \dfrac{30}{380}+\dfrac{84}{380}[/tex]
[tex]\rm P =\dfrac{114}{380}[/tex]
P = 0.33
So, the probability that the second ball drawn is a white ball if the second ball is drawn without replacing the first ball is 0.33.
Therefore, the correct option is a).

Okay, I'm pretty sure about this one! I might be wrong but:
If the number is prime and LESS than 13 (so it can't be 13 either), it's either 2, 3, 5, 7, or 11. Those are 5 numbers in all, and 4 of those are odd. So the fraction would be 4/5!

For horizontal lines, m=0. For slanted lines, m can have any real value.
Vertical lines have an infinite slope and the above equation cannot be used.

There are 80 tickets in a bag and the ratio of winning tickets to losing tickets is 2:8. How many of each kind of ticket are in the bag?
Answers
Answer:
There are 16 winning tickets and 64 losing tickets
Step-by-step explanation:
Total no of tickets in a bag = 80
The ratio of winning tickets to losing tickets is 2:8.
Let there are 2x winning tickets and 8x losing tickets.
ATQ,
2x+8x=80
10x=80
x = 8
Winning tickets = 2x = 2(8) = 16
Losing tickets = 8x = 8(8) = 64
Hence, there are 16 winning tickets and 64 losing tickets.
2. Solve the following pair of simultaneous equations

0.8x -3.5y =0.5

Answers
Answer:
After solving the pair of simultaneous equations we get x=5 and y=1. Solution Set = {5,1}
Step-by-step explanation:
We need to solve the pair of simultaneous equations
[tex]0.6x-4y=-1\\0.8x-3.5y=0.5[/tex]
We can solve using substitution method.
Let:
[tex]0.6x-4y=-1--eq(1)\\0.8x-3.5y=0.5--eq(2)[/tex]
Find value of x from eq(1) and put it in eq(2)
[tex]From \ eq(1):\\0.6x-4y=-1\\0.6x=-1+4y\\x=\frac{-1+4y}{0.6}[/tex]
Putting in equation 2
[tex]0.8x -3.5y =0.5\\0.8(\frac{-1+4y}{0.6})-3.5y=0.5\\1.33(-1+4y)-3.5y=0.5\\-1.33+5.32y-3.5y=0.5\\-1.33+1.82y=0.5\\1.82y=0.5+1.33\\1.82y=1.83\\y=\frac{1.83}{1.82}\\y=1.00[/tex]
So, we get value of y= 1.00
Now finding value of x by putting value of y in eq(1)
[tex]x=\frac{-1+4y}{0.6}\\x= \frac{-1+4(1.00)}{0.6}\\x=\frac{3}{0.6}\\x=5[/tex]
We get value of x = 5
So, After solving the pair of simultaneous equations we get x=5 and y=1. Solution Set = {5,1}

If the expression ax^4 + bx^3 – x² + 2x + 3 has a remainder
3x+5
when it is divided x^2-x-2 find the values a and b
Answers
There's probably a more efficient way to do it, but the following method works.
First, note that
x² - x - 2 = (x + 1) (x - 2)
Now use synthetic division to divide
a x⁴ + b x³ - x² + 2x + 3
by the two factors above.
Division by x + 1 :
-1 | a b -1 2 3
… | -a a - b -a + b + 1 a - b - 3
= = = = = = = = = = = = = = = = = = = = = = = = = = = = =
… | a b - a a - b - 1 -a + b + 3 a - b
which is to say,
(a x⁴ + b x³ - x² + 2x + 3) / (x + 1)
= a x³ + (b - a) x² + (a - b - 1) x + (-a + b + 3) + (a - b) / (x + 1)
Division by x - 2 :
2 | a b - a a - b - 1 -a + b + 3
… | 2a 2a + 2b 6a + 2b - 2
= = = = = = = = = = = = = = = = = = = = = = = = = = =
… | a a + b 3a + b - 1 5a + 3b + 1
meaning,
(a x³ + (b - a) x² + (a - b - 1) x + (-a + b + 3)) / (x - 2)
= a x² + (a + b) x + (3a + b - 1) + (5a + 3b + 1) / (x - 2)
Putting everything together, we have
(a x⁴ + b x³ - x² + 2x + 3) / (x² - x - 2)
= a x² + (a + b) x + (3a + b - 1) + (5a + 3b + 1) / (x - 2) + (a - b) / (x² - x - 2)
Combine the remainder terms:
(5a + 3b + 1) / (x - 2) + (a - b) / (x² - x - 2)
= ((5a + 3b + 1) x + (6a + 2b + 1)) / (x² - x - 2)
We're given that the remainder is 3x + 5, so
5a + 3b + 1 = 3
6a + 2b + 1 = 5
Solve this system for a and b :
5a + 3b = 2
6a + 2b = 4
5a + 3b = 2
3a + b = 2
5a + 3b = 2
-9a - 3b = -6
(5a + 3b) + (-9a - 3b) = 2 + (-6)
-4a = -4
a = 1
5 • 1 + 3b = 2
3b = -3
b = -1

How tall is the scale model giraffe in inches?
Enter your answer in the box.
inches
Answers
Answer:
The scale model giraffe is 5 inches tall.
Step-by-step explanation:
To determine the size of the giraffe sculpted by the artist, knowing that it has been built on a scale of 1 inch for every 4 feet, and knowing that the real giraffe in the zoo is 20 feet, the following calculation must be performed:
20 feet / 4 inches = X
5 = X
Therefore, the size of the giraffe sculpted to scale by the artist is 5 inches.
