A passbook savings account has a rate of 5%. Find the effective annual yield if the interest is compounded quarterly.
Temka [501]

Answer:

Effective annual yield = 0.05094534 or 5.094%

Step-by-step explanation:

Given:

Rate of interest (r) = 5% = 0.05

Interest = compounded quarterly

Find:

Effective annual yield = Y

Computation:

Y=(1+\frac{r}{n} )^n-1\\\\Y=(1+\frac{0.05}{4} )^4-1\\\\Y=(1+0.0125 )^4-1\\\\Y=(1.0125 )^4-1\\\\ Y=1.05094534-1\\\\Y=0.05094534\\\\\\

Effective annual yield = 0.05094534 or 5.094%

the population of mastertown was 23,000 in 2012. assume that mastertowns population increases at a rate of 2% per year. write an
Assoli18 [71]
So, after one year will will have the new population of 23 000 * (100 %+2%)
(the 100 % is the old population and the 2% is the increase), that is:

23000*1.02=23460

(102 % can be represented as 1.02)

And for the next years, we have to repeat the procedure.

a more generic rule would be:

y=23000*1.02^{x} (x is the number of years passed)

fgiga [73]

Answer:

Correct option is (B) descriptive statistical method

Step-by-step explanation:

Descriptive statistics branch in statistics deals with the representation of the data using distinct brief coefficients. These coefficients are used as either the representative of the sample or the population.

The descriptive statistics branch is divided into two sub branches:

  1. Measure of central tendency
  2. Measure of dispersion.

The three measures of central tendency are:

  • Mean (or Average)
  • Median
  • Mode.

The measures of dispersion are:

  • Variance
  • Standard deviation
  • Range
  • Kurtosis
  • Skewness

The education researcher computes the average number of hours student study at various local colleges.

The average of a data is the mean value which is the measure of central tendency.

Thus, the researcher is using descriptive statistical method to summarize the data.

Identify the missing base of the trapezoid, given that A=36 cm∧2. HELP PLEASE!!
den301095 [7]

Answer:

6 cm

Step-by-step explanation:

A = 1/2(b + 12)(4)

36 = 1/2(b + 12)(4)

72 = (b + 12)(4)

18 = b + 12

18 - 12 = b

6 = b

or

b = 6 cm
