Answer:

21 times

Step-by-step explanation:

Given

$P(3) = 50 \%$

$n =42$

Required

The least number of times to land on 3

This is calculated using:

$Least = n * P(3)$

$Least = 42 * 50\%$

$Least = 21$

A researcher is interested in knowing the average height of the men in a village. To the researcher, the population of interest

Anna11 [10]

Answer:

The population mean height of men in the village is 5.78 feet.

The sample mean height of men in the village is 7.8 feet.

Step-by-step explanation:

It is provided that the researcher's interest is in knowing the average height of the men in a village.

To the researcher, the population of interest is the men in the village, the relevant population data are the height of men in the village, and the population parameter of interest is the mean height of men.

It is also provided that there are 590 men in the village, and the sum of their heights is 3,410.2 feet.

Compute the average height as follows:

$\bar X_{H}=\frac{3410.2}{590}=5.78\ \text{feet}$

Thus, the population mean height of men in the village is 5.78 feet.

It is given that the researcher measured the heights of 18 village men and calculated the average to estimate the average height of all the village men.

The sample for his estimation is 18 men, the relevant sample data are the heights of the 18 men, and the sample statistic is the sample mean height.

It is also given that the sum of the heights of the 18 village men is 104.4 feet.

Compute the average height of the 18 men as follows:

$\bar x_{H}=\frac{104.4}{18}=7.8\ \text{feet}$

Thus, the sample mean height of men in the village is 7.8 feet.

Please hwelp please

Fantom [35]

Answer:

2⁸ > 2.38 × 10² > 6³ > 2.16 × 10¹ > $\sqrt{300}$ , 300%

Step-by-step explanation:

Given numbers are,

2.38 × 10², √300, 2⁸, 300%, 6³, 2.16 × 10¹

We have to arrange these numbers in the decreasing order(from greatest to least)

2.38 × 10² = 2.38 × 100 = 238

√300 = 10√3 ≈ 17.32

2⁸ = 256

300% = $\frac{300}{100}$ = 3

6³ = 216

2.16 × 10¹ = 21.6

Therefore, decreasing order (from the greatest to least) will be,

256 > 238 > 216 > 21.6 > 17.32 > 3

2⁸ > 2.38 × 10² > 6³ > 2.16 × 10¹ > $\sqrt{300}$ , 300%

Part A

Nitella [24]

Answer:

P = 300

r = 0.15

n = 12

A(t) = 300(1.0125)^12t

Step-by-step explanation:

Given that:

Total credit taken for book purchase = $300

Annual Interest rate = 15% compounded monthly

Time or period = 4 years

P(1 + r/n)^nt

P in the expression above means the principal amount which is the total credit spent on book purchase = $300

r = annual interest rate on Emma's account = 15% = 15/100 = 0.15

n = number of compounding times per period ; loan which compounds monthly = number of months in a year = 12

Hence,

P = $300 ; r = 0.15 ; n = 12

Substituting into the equation :

P(1 + r/n)^nt

Simplified expression written in terms of t:

Final amount, A after t years

A(t) = 300(1 + 0.15/12)^12t

A(t) = 300(1 + 0.0125)^12t

A(t) = 300(1.0125)^12t
