ra1l [238]
The exponential function equivalent to 4=ln x will be evaluated as follows:
from 
4=ln x
introducing the exponential function
e^4=e^(lnx)
but
e^(lnx)=x
thus
e^4=x

Exhibit: Department Store.
aalyn [17]

Answer:

Step-by-step explanation:

Considering the central limit theorem, the distribution is normal since the number of samples is large.

Confidence interval is written in the form,

(Sample mean - margin of error, sample mean + margin of error)

The sample mean, x is the point estimate for the population mean.

Confidence interval = mean ± z × σ/√n

Where

σ = population standard Deviation

σ/√n = sample standard deviation

Confidence interval = x ± z × σ/√n

1) x = $75

σ = $24

To determine the z score, we subtract the confidence level from 100% to get α

α = 1 - 0.96 = 0.04

α/2 = 0.04/2 = 0.02

This is the area in each tail. Since we want the area in the middle, it becomes

1 - 0.02 = 0.98

The z score corresponding to the area on the z table is 2.05. Thus, confidence level of 96% is 2.05

Confidence interval = 75 ± 2.05 × 24/√64

= 75 ± 2.05 × 3

= 75 ± 6.15

The lower end of the confidence interval is

75 - 6.15 = 68.85

The upper end of the confidence interval is

75 + 6.15 = 81.15

2) n = 400

x = $75

σ = $24

z = 2.05

Confidence interval = 75 ± 2.05 × 24/√400

= 75 ± 2.05 × 1.2

= 75 ± 2.46

The lower bound of the confidence interval is

75 - 2.46 = 72.54

The upper bound of the confidence interval is

75 + 2.46 = 77.46

3) n = 400

x = $200

σ = $80

The z score corresponding to the confidence level of 94% is 1.88

z = 1.88

Confidence interval = 200 ± 1.88 × 80/√400

= 200 ± 1.88 × 4

= 200 ± 7.52

Margin of error = 7.52

The sum of 1/11 and 1/15 is closest to....
Afina-wow [57]
\frac{1}{11}+\frac{1}{15}=\frac{1\cdot15}{11\cdot15}+\frac{1\cdot11}{15\cdot11}=\frac{15}{165}+\frac{11}{165}=\frac{15+11}{165}=\frac{26}{165} < \frac{1}{2}\\\\\frac{1}{11}+\frac{1}{15}\approx0

What are the 5 infinitives?
Ymorist [56]

The five types of infinitives are full infinitives, bare infinitives, split infinitives, continuous infinitives , and perfect continuous infinitive.

Explanation:

Types of infinitives:

Five types of infinitives are as follow:

  • Full infinitives : Add 'to' Infront of the verb to complete the the situation.
  • Bare infinitives: here " to" get omitted from the sentence.
  • Split infinitives : Here adjectives slides between infinitives marker.

To hear : full infinitives changes to split infinitives : to slowly hear.

  • Continuous infinitives: Action going for certain period of required time.

Example : to be missing

  • Perfect continuous infinitives: prior to a time :

Example : to have seen

Therefore, there are are five types of infinitives .
