Let f(x)=15/(1+4e^(-0.2x)

1 answer:

6 0

The interval of growth rate can be seen in the graph below

The answer is (-∞, ln(4)/0.2) = (-∞, 6.9314)

(As x goes to infinity f(x) goes to 15)

Sixes=8

Runs from boundaries

3(4)+8(6)=12+48=60runs

Runs from running between the wickets=110-60=50runs

Percentage:-

$\\ \sf\longmapsto \dfrac{50}{110}\times 100$

2. P337. 23. A large box contains 10,000 ball bearings. A random sample of 120 is chosen. The sample mean diameter is 10 mm, and

Rashid [163]

Answer:

B is True

A, C. D are false

Step-by-step explanation:

Given :

Sample size, n = 120

Mean diameter, m = 10

Standard deviation, s = 0.24

Confidence level, Zcritical ; Z0.05/2 = Z0.025 = 1.96

The confidence interval represents how the true mean value compares to a set of values around the mean computed from a set of sample drawn from the population.

The population here is N = 10000

To obtain

Confidence interval (C. I) :

Mean ± margin of error

Margin of Error = Zcritical * s/sqrt(n)

Margin of Error = 1.96 * 0.24/sqrt(120)

Confidence interval for the 10,000 ball bearing :

10 ± 1.96 * (0.24) / sqrt(120)

Hence. The confidence interval defined as :

10 ± 1.96 * (0.24) / sqrt(120) is the 95% confidence interval for the mean diameter of the 10,000 bearings in the box.
