Answer:
0.6848
Step-by-step explanation:
Mean of \hat{p} = 0.453
Answer = 0.453
Standard deviation of \hat{p} :
= \sqrt{\frac{\hat{p}(1-\hat{p})}{n}} = \sqrt{\frac{0.453(1-0.453)}{100}} = 0.0498
Answer = 0.0498
P(0.0453 - 0.05 < p < 0.0453 + 0.05)
On standardising,
= P(\frac{0.0453-0.05-0.0453}{0.0498} <Z<\frac{0.0453+0.05-0.0453}{0.0498})
= P(-1.0044 < Z < 1.0044) = 0.6848
Answer = 0.6848
Answer:
0.01
Step-by-step explanation:
300 seconds = 2.75 pies
1 second = (1/300) × 2.75
= 0.009167
Approximately, 0.01 pie

Answer:
34a^2 + 21a - 20
Step-by-step explanation:
(12a^2 + 6a -8) - (-22a + 12 - 15a)
12a^2 + 6a - 8 + 22a + 12 - 15a
34^2 + 6a - 8 - 12 + 15a
34^2 + 21a - 20
Answer: 112 pieces
Step-by-step explanation:
1. Rewrite 
as a decimal. Divide the numerator and the denominator of the fractional part and add it to the integer part:
2. You know that each metal rod is 15 inches long. Then, you must divide the lenght of each one by 3.6:
3. The waste is 0.16, therefore, you obtain 4 pieces from a metal rod. The total pieces obtained from 28 metal rods are:
