What is the difference between an estimator and an ​estimate? A. An estimator is a function of a sample of data to be drawn rand

omly from a population whereas an estimate is the numerical value of the estimator when it is actually computed using data from a specific sample. B. Both an estimator and an estimate are functions of a sample of data to be drawn randomly from a population. C. Both an estimator and an estimate are numerical values computed using data from a specific sample. D. An estimate is a function of a sample of data to be drawn randomly from a population whereas an estimator is the numerical value of the estimator when it is actually computed using data from a specific sample.

Answer: A. An estimator is a function of a sample of data to be drawn randomly from a population whereas an estimate is the numerical value of the estimator when it is actually computed using data from a specific sample.

Step-by-step explanation: The estimator is simply used to on obtaining an estimate from a sample of data. Thus, the estimator may be described as a function built according to a set of defined rules and statistical component which is used to infer a numerical value of an estimate from a given sample of observed data. Hence, the estimator may be regarded as the function or rules adopted in our quest to obtain an estimate for a given population from a sample of data. The value obtained for the mean of a sample of data is called an estimate of the population, the rules for Deriving the estimated value is called the estimator.

I NEED HELP PLEASE, THANKS! :) Heather invests $4,900 in an account with a 3.5% interest rate, making no other deposits or withd
Alex

Answer:    $5,828.28

<u>Step-by-step explanation:</u>

Use the Compound Interest formula:     A=P(1+\frac{r}{n})^{nt}       where

  • A is the accrued amount (balance)
  • P is the principal (initial amount invested)
  • r is the interest rate (in decimal form)
  • n is the number of times compounded each year
  • t is the time of the investment (in years)

Given: P = 4,900

           r = 3.5% (0.035)

           n = 2

           t = 5

A=4,900\bigg(1+\dfrac{0.035}{2}\bigg)^{2(5)}\\\\\\.\qquad = 4900(1.0175)^{10}\\\\\\.\qquad = \large\boxed{5,828.28}\\

19. Given that angle BFC = 58°. Angle BXG = 48° and angle CBF 22 Find () 2BGX (iv) BCG (i) 2BGF (iv) ZBFG (ii) BCF H EE 58 48° D
RoseWind [281]

The unknown angles in the cyclic quadrilateral is as follows:

∠BGX = 74° (sum of angles in a triangle)

∠BGF = 180° (opposite angles of cyclic quadrilateral are supplementary)

∠BCF = 100°(sum of angles in a triangle)

∠BCG  = 26°

∠BFG = 22°

<h3>Cyclic Quadrilateral</h3>

A cyclic quadrilateral has all its angles equal to 360 degrees. The sum of angles in a cyclic quadrilateral is equals to 360 degrees.

Let's find the missing angles as follows:

∠BGX = 180 - 48 - 58 = 74° (sum of angles in a triangle)

∠BGF = 180 - 100 = 80° (opposite angles of cyclic quadrilateral are supplementary)

∠BCF = 180 - 22 - 58 = 100°(sum of angles in a triangle)

∠BCG = 100 - 74 = 26°

∠BFG ≅ CBF = 22°(alternate angles)

How much interest is earned on $2,700 in one year if it is invested at 3%?
tester [92]
On this part, you can use the formula for compound interest: 

F = P(1+i)^n 
F = future worth of $ 
P = present worth of $ 
i=interest 
n=years 

F = 2700(1+0.03)^1 
F = 2781 

<span>So interest = 2781-2700 = $81
