Answer:
the algebraic expression that represent the quotient of a number & thirty is 30 ÷ a
Step-by-step explanation:
The algebraic expression that represent the quotient of a number & thirty is shown below:
As we know that
Quotient means to divide
So here the quotient is 30
And the other number would be 30 ÷ a
Therefore the algebraic expression that represent the quotient of a number & thirty is 30 ÷ a
The answer is 44/7 hope this helps
The second option - 3/25.
The probability of the first one is 3 blue socks over 10 socks in total = 3/10
The probability of the second one is 4 red socks over 10 socks in total = 4/10
Multiply the two probabilities to get the probability of having the first sock as blue and the second sock as red.
3/10 * 4/10 = 3/25
Answer:
Step-by-step explanation:
Given
Required
Find P(A) and P(B)
We have that:
--- (1)
and
--- (2)
The equations become:
--- (1)
Collect like terms
Make P(A) the subject
--- (2)
Substitute:
![[0.770 - P(B)] * P(B) = 0.144](https://tex.z-dn.net/?f=%5B0.770%20-%20P%28B%29%5D%20%2A%20P%28B%29%20%3D%200.144)
Open bracket
Represent P(B) with x
Rewrite as:
Expand
Factorize:
![x[x - 0.45] - 0.32[x - 0.45]= 0](https://tex.z-dn.net/?f=x%5Bx%20-%200.45%5D%20-%200.32%5Bx%20-%200.45%5D%3D%200)
Factor out x - 0.45
![[x - 0.32][x - 0.45]= 0](https://tex.z-dn.net/?f=%5Bx%20-%200.32%5D%5Bx%20-%200.45%5D%3D%200)
Split
Solve for x
Recall that:
So, we have:
Recall that:
So, we have:
Since:
Then:
