Answer:
0.100 ;
0.6673 ;
0.446 ;
0.311
Explanation:
Given that :
p = 49% = 0.49
Sample size, n = 45
From binomial probability formula:
P(x =x) = nCx * p^x * (1 - p)^(n - x)
Exactly 24 of them are repeat offenders.
P(x = 24) = 45C24 * 0.49^24 * 0.51^21 = 0.100
b. At most 23 of them are repeat offenders.
P(x ≤ 23) = p(x = 0) + p(x = 1)... + p(x =23)
P(x ≤ 23) = 0.6673 (using online binomial probability calculator)
c. At least 23 of them are repeat offenders.
P(x ≥ 23) = p(x = 23) + p(x = 24)... + p(x =45)
P(x ≥ 23) = 0.445 (using online binomial probability calculator)
d. Between 15 and 20 (including 15 and 20) of them are repeat offenders.
P(x = 15) + p(x = 16) + p(x = 17) p(x = 18) p(x = 19) +
p(x = 20)
0.0131 + 0.0236 + 0.0387 + 0.0579 + 0.0790 + 0.0987
= 0.311
It might be Diverse? Since diverse means showing a great deal of variety
Answer:
When light passes through to samples of CuSO₄, the percent transmittance of light, %T, will be lower for Sample 1 compared to Sample 2.
Answer:
the speed of light in glass is slower than the speed of light in space
Density = mass / volume
mass = 44 g
volume = 9 cm³
Density = 44 g / 9 cm³ ≈ 4.9 ≈ 5 g/cm³
