Suppose the probability of being picked first in your class is 0.05. The odds of being picked first expressed in form of a: b is 1 : 19.
A probability is a number that represents the possibility or chance that a specific event will occur.
[tex]{\mathbf{\text{The probability of an event} = \dfrac{\text{number of desired outcome}}{\text{total number of possible outcome}}}[/tex]
From the given information;
Let assume the total number of people in the class is whole = 1∴
The odds of being picked first can be computed as:
[tex]\mathbf{=\dfrac{0.05}{1-0.05}}[/tex]
[tex]\mathbf{=\dfrac{0.05}{0.95}}[/tex]
[tex]\mathbf{\dfrac{1}{19}}[/tex]
= 1 : 19
Therefore, the odds of being picked first in terms of a: b is 1 : 19

If (10,3) and (6,31) are two anchor points on a trend like, then find the equation of the line
Answer:
let's find the gradient first. (m)
Step-by-step explanation:
(10,3) (6,31)
y²-y¹/x²-x¹
31-3/6-3
28/3
(m) =28/3
y-y¹=m(x-x¹)
let's take y¹=3, x¹=10 and m= 28/3
y-3=28/3(x -10)
y-3=(28/3)x -128/3
taking LCM=3
3y-9=28x-128
3y=28x -128+9
3y=28x-119

Juan solved the system of linear equations
8x - 3y = -1
and
-5x+2y = 1
a. First, he multiplied the equation
8x - 3y = -1
by 2 to get
b. Next, he multiplied the equation
-5x+2y = 1
by 3 to get
c. Then he added the two resulting equations together to get
d. Finally, he substituted the result into one of the original equations and solved
Answer:
x =1
y = 3
Step-by-step explanation:
8x - 3y = -1 ------ * 2 part (a)
-5x +2y =1 ------ * 3 part (b)
16x -6y = -2 part (c)
-15x +6y = 3
x = 1
8(1) - 3y = -1 part (d)
8-3y =-1
-3y = -9
y =3
Find the product of 2 5/6 and 3
Answer:

Step-by-step explanation:
To find the product of 2 5/6 and 3, you can multiply the two numbers together.
2 5/6 x 3 is equal to 8.5, therefore, the product of these two numbers is 8 1/2.
1/2x - 5+ 2/3 x= 7/6x+4
Doug has a shelf 9 3/4 inches long for storing CDs. Each CD is 3/8 inches wide. How many CDs will fit in one shelf?
Answer:
26 CD's
Step-by-step explanation:
If the shelf is 9 3/4 inches long, and each CD is 3/8, all we have to do is divide. We get 26.
First:
Convert any mixed numbers to fractions.
Then your equation becomes:
39/4÷3/8
Applying the fractions formula for division,
=39×8/4×3
=312/12
Simplifying 312/12, the answer is
=26

help!! Is anyone good at algebra??
Answer:
h = 20 m
Step-by-step explanation:
So you know volume of a cylinder = π*(r^2) * h
and you also know volume of this cylinder = 180π
(volume is also in meters^3)
you can set these volumes equal to one another
180π = π*(r^2) * h
by dividing by π you get this:
180 = (r^2) * h
you need h so you can divide by r^2 to get this
h = 180 / (r^2)
now you just need to plug in the radius you are given which was 3 meters
h = 180 m^3 / (3 m^2)
h = 180 m^ 3 / 9 m^2
h = 20 m
which is closer to one, 7/8 or 8/7?
Explain without converting to decimals or using common denominators.
9514 1404 393
Answer:
7/8
Step-by-step explanation:
7/8 differs from 1 = 8/8 by 1/8.
8/7 differs from 1 = 7/7 by 1/7.
1/8 is smaller than 1/7, so 7/8 is closer to 1.

For g(x)=x2 +6, find g(x) when x
1 and when x = 2.
Answer:
g = 10
Step-by-step explanation:
(Assuming that x=1 is the first x and x=2 is the second...)
g(1) = 2(2) + 6
Simplify, g x 1 = g and 2 x 2 = 4
g = 4 + 6
Simplify, 4 + 6 = 10
g = 10
Hope this helps :)
