Answer:
0.9544
Step-by-step explanation:
P(-2 < Z < 2) means that Z has mean 0 and standard deviation 2.
P(−2 < Z < 2) = F(2) - F(-2)
Using the Z - table,
F(2) = 0.9772
and F(-2) = 0.0228
Thus,
P(−2 < Z < 2) = 0.9772 - 0.0228 = 0.9544
This means that data within two standard deviation is 95%.

Associative property (associative laws)
13. 44 + 40 = 84
14. 15 + 81 = 96
15. 13 + 52 = 65
16. 64 + 28 = 92
Answer:
3l + 1s
Step-by-step explanation:
Given that:
The expression to represent 50% of the money collected : 0.50(6l + 2s)
Expanding the expression :
0.50(6l + 2s)
(0.50 * 6l) + (0.50 * 2s)
3l + 1s
Hence, the simplified expression is 3l + 1s
