Answer:

x=3

Step-by-step explanation:

If the triangles are congruent

13 = 4x+1

subtract 1 from each side

13-1 = 4x+1-1

12=4x

Divide by 4

12/4 = 4x/4

3=x

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.

Hello, this is math and I need help ❤️ pls and ty ONLY SERIOUS ANSWERS
Greeley [361]

The bicycle with a 30-inches diameter rolls approximately 28.8 more than a tire with the diameter with 21-inches.

<u><em>How to solve:</em></u>

  • First use the formula: C = 3.14d
  • Replace the d value with 30 and solve the equation:

C = 3.14 x 30    ⇒   94.2477796077

  • Then solve the equation again but 21 as the d value:

C = 3.14 x 21     ⇒   65.9734457254

  • Then subtract 65.9734457254 from 94.2477796077 to get the approx. answer of 28.8
