Answer:
a. 81.5%
Step-by-step explanation:
The z-score for 400 is ...
Z = (X -μ)/σ = (400 -500)/100 = -1
The z-score for 700 is ...
Z = (700 -500)/100 = 2
The empirical rule tells you that 68% of the distribution is within ±1σ of the mean, and 95% is within ±2σ of the mean. Half of that first number is in the range Z = -1 to 0, and half that second number is in the range Z = 0 to +2. So, the probability you want is ...
(1/2)(68%) + (1/2)(95%) = 81.5% . . . . matches choice A
Answer:
Any expression doesn't have the same value
Step-by-step explanation:
<h3>1. 23-82</h3>
Subtract 82 from 23.
−59
<h3>2. 23 - (8 x 2)</h3>
Simplify each term.
Multiply 8 by 2.
23−1⋅16
Multiply −1 by 16.
23−16
Subtract 16 from 23.
7
<h3>3. (23 -8) x 2</h3>
Subtract 8 from 23.
15⋅2
Multiply 15 by 2.
30

2- 12.5%
The hours between 12-8 is a total of 8 hours
6 to 8 is a total of 2 hours
2/8 is 25 percent but there are two days on the weekend so therefore it’s a 50 50 Chance to play on Sunday so divide 25 in half and you get 12.5 %
