Answer:
2.00
Step-by-step explanation:
Z score is a statistical that corresponds to the standardization of the regular score to a normal distribution
The formula for Z score is Z = [X - mean ]./ (standard deviation)
Here X = 930.00; mean = 900.00; and standard deviation = 15.00
Then, Z = [930.00 - 900.00] / 15.00 = 30.00 / 15.00 = 2.00
Answer:
0.1575.
Step-by-step explanation:
Here, as they are independent, we multiply the probabilities:
P( A and B) = 0.35*0.45
= 0.1575.

Answer:
18.852
Step-by-step explanation:
Formula to find the arc of semi circle is :
Arc length = π r
Given that,
diameter ⇒ 12
So, the radius will be,
Radius ⇒ 12 / 2
⇒ 6
<u>Let us solve now.</u>
Arc length = π r
= 3.142 × 6
=<u> 18. 852</u>
