Answer:
The probability Democrat is selected given that this member favors some type of corporate tax reform is 0.6309.
Step-by-step explanation:
Let us suppose that,
R = Republicans
D = Democrats
I = Independents.
X = a member favors some type of corporate tax reform.
The information provided is:
P (R) = 0.27
P (D) = 0.56
P (I) = 0.17
P (X|R) = 0.34
P (X|D) = 0.41
P (X|I) = 0.25.
Compute the probability that a randomly selected member favors some type of corporate tax reform as follows:
The probability that a randomly selected member favors some type of corporate tax reform is P (X) = 0.3639.
Compute the probability Democrat is selected given that this member favors some type of corporate tax reform as follows:
Thus, the probability Democrat is selected given that this member favors some type of corporate tax reform is 0.6309.

<h2>Hello!</h2>
The answer is:
It will take 4.5 hours for two bricklayers to lay a total of 3150 bricks.
<h2>Why?</h2>
From the statement, we know that on Monday, bricklayers took 3 hours to lay a total of 4200 bricks.
So, we have that the rate of the four bricklayers is given by the following equation:
Therefore, we have that the rate of the four bricklayers is 1400 bricks per hour, meaning that each bricklayer can lay 350 bricks per hour.
Now, to calculate how many hours it will take to the 2 bricklayers to lay a total of 3150, we need to divide the calculated rate (for bricklayers) by two, since there are only 2 bricklayers working on Tuesday.
So, calculating the time, we have:
Hence, we have that it will take 4.5 hours for two bricklayers to lay a total of 3150 bricks.
Have a nice day!

Answer:
28 small
9 large
Step-by-step explanation:
4200 ÷ 150 = 28 small
4200 ÷ 450 =9 large
