Answer:

A) $6

Step-by-step explanation:

divide the 12 on the right by the 2 on the left. This gets X by itself. 12/2 is 6, therefor oyur sandwhich costs $6

You have a standard deck of 52 cards. You pick one card from the deck and then, without putting the first one back, pick a secon

Nina [5.8K]

Set up the two events
A = first card is a 9
B = second card is a 9

The probability for event A is
P(A) = 4/52
because there are four "9" cards out of 52 total

If event A happens first, and B follows, then the probability is
P(B|A) = 3/51
because there are 3 nines left over out of 52-1 = 51 total left over
No replacement has been made
The notation P(B|A) means "probability of event B given that event A has happened"

Multiply the probabilities
P(A and B) = P(A)*P(B|A)
P(A and B) = (4/52)*(3/51)
P(A and B) = (4*3)/(52*51)
P(A and B) = 12/2652
P(A and B) = 1/221
P(A and B) = 0.00452488687782

Rounded to 4 decimal places, the approximate answer is 0.0045
The exact answer as a fraction is 1/221

The required equation of line parallel to given line is: $y = \frac{5}{6}x-8$

Step-by-step explanation:

Given equation of line is:

$y = \frac{5}{6}x+1$

As the equation of line is in slope-intercept form, the co-efficient of x s the slope

Let m1 be the slope of given line

m1= 5/6

Let m2 be the slope of new line

As the slopes of two parllel lines are equal, so

m1 = m2

m2 = 5/6

The slope intercept form is:

$y= m_2x+b$

Put m2 = 5/6 in equation

$y = \frac{5}{6}x+b$

Putting the point in the equation

$2 = \frac{5}{6}(12)+b\\2=10+b\\b = 2-10\\b = -8$

Putting the value of b, we get

$y = \frac{5}{6}x-8$

Hence,

The required equation of line parallel to given line is: $y = \frac{5}{6}x-8$

Suppose task B follows task A. The likelihood that a problem will occur with task A is 0.5, and the time to correct the problem

jasenka [17]

Answer:

The risk consequence of both activities is 1.6 months.

Step-by-step explanation:

We can define a randome variable D: total delay time for the project, and calculate its expected value.

This would be the risk consequence of both activities.

The expected delay time for the project is the sum of the expected delay for task A plus the expected delay for task B. It is assumed the likelihood of a problem in any task is independent of the other.

Then, each expected delay for a task is equal to the probability of a problem multiplied by the consequence (delay time).

$E(D)=E(D_a)+E(D_b)=p_aT_a+p_bT_b\\\\E(D)=0.5*2+0.2*3=1+0.6=1.6$

The risk consequence of both activities is 1.6 months.
