Find the value of x, plz help me soon it’s due in a few mins

ch4aika [34]

Answer:

The value of x is 13°

Step-by-step explanation:

<u>Given:</u> m || n

For a straight line = 180°

Now, by exterior angle

(7x - 1)° + (8x - 14)° = 180°

7x - 1° + 8x - 14° = 180°

15x - 15° = 180°

Now, add 15° both side we get,

15x - 15° + 15° = 180° + 15°

15x = 195°

Now, divide both side by 15

15x/15 = 195°/15

x = 13°

Thus, The value of x is 13°

Consider a project that has an expected completion time of 60 weeks and a standard deviation of five weeks. What is the probabil

Nana76 [90]

Answer: 0.3413

Step-by-step explanation:

Given :Mean : $\mu=60\text{ weeks}$

Standard deviation : $\sigma = 5\text{ weeks}$

The formula for z -score :

$z=\dfrac{x-\mu}{\sigma}$

For x= 60 ,

$z=\dfrac{60-60}{5}=0$

For x= 65 ,

$z=\dfrac{65-60}{5}=1$

The p-value = $P(0$

$= 0.8413447-0.5= 0.3413447\approx0.3413$

Hence, the probability that the project will take anywhere between 60 and 65 weeks to complete = 0.3413.
