An individual chooses a prime number that is less than 13. What is the probability that the number is odd? Write your answer as an exact fraction which is reduced as much as possible.
Answer:
4/5
Step-by-step explanation:
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!

Answer:
Step-by-step explanation:
24^2 + b^2 = 40^2
576 + b^2 = 1600
b^2 = 1024
b = 32
32
Step-by-step explanation:
[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]
a= 24 , b= b , c=40
In order to find b, you have to change the equation a bit. Your new equation will look like [tex] {c}^{2} - {a}^{2} = {b}^{2} [/tex]
here is the step by step now
[tex] {40}^{2} - {24}^{2} = {b}^{2} [/tex]
[tex] {1600} - {576} = {b}^{2} [/tex]
[tex] {1024} = {b}^{2} [/tex]
**now you need to take the square root of both sides and you get 32**

-3x + 7 y = -16
-9x + 5y = 16
Answer:
x = -4y = -4Step-by-step explanation:
-3x + 7y = -16 (-3) to eliminate x
-9x + 5y = 16
9x - 21y = 48
-16y = 64
y = 64/-16
y = -4
substitute y= -4 into eq. 1
-3x + 7y = -16
-3x + 7(-4) = -16
-3x = -16 + 28
x = 12 / -3
x = -4
check:
-3(-4) + 7(-4) = -16
- 16 = -16 ok
-9x + 5y = 16
-9(-4) + 5(-4) = 16
16 = 16 ok
Answer:
x=44/3, y=4
Step-by-step explanation:
Assuming you have to solve for x and y
-3x+ 7y = -16 (1)
-9x+ 5y =16 (2)
multiply (1) by -3 and add it to (2)
9x-21y=48
-9x+5y=16
Add up and get
-21y+5y=48+16 combine like terms
16y=64 divide both sides by 16 and get
y=4
Substitute y=4 in (1)
-3*x+7*4=-16
28+16=3x
44=3x
x=44/3

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
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

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?
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.
An artist sculpted a scale model of a giraffe for the zoo gift shop. The artist used the scale 1 inch: 4 feet to create the scale model giraffe. The actual giraffe at the zoo is 20 feet tall.
How tall is the scale model giraffe in inches?
Enter your answer in the box.
inches
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.

Help please this sucks lol
Answer:
x = -4
Step-by-step explanation:
Equation of the Line
It can be written in the slope-intercept form as:
y = mx + b
Where m is the slope of the line and b is the y-intercept.
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.
Vertical lines have a fixed value for x, thus the equation is:
x = h
If the vertical line goes through the point (-4,1), then its equation is:
x = -4
2. Solve the following pair of simultaneous equations
0.6x - 4y=-1
1
0.8x -3.5y =0.5
2
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}

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
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).

What is the greatest common factor of 72 and 34?
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
