5x - 4x = -4 + 40

x = 36

∠BCA = 3 * 36 + 4 = 112

Identify the level of measurement of the​ data, and explain what is wrong with the given calculation. In a​ survey, the hair col
Arada [10]

Answer:

Nominal level of measurement

Step-by-step explanation:

The level of measurements used in this study is the nominal level of measurements. The nominal level of measurements involves the use of numbers to help classify the categories in an experiment.

In this case study, values were gotten for each categories which are brown hair, blonde hair, black hair and other hair colors. Thus, the level of measurements used is the nominal level of measurement.

There is something wrong with the calculation because data was gotten for a total of 600 respondents while the mean that was calculated involved only 503 omitting about 97 respondents.

Why does the fraction 20/25 not belong with 1/20, 2/3 and 5/4?
devlian [24]
I’m not 100% sure but I think it’s because 20/25 can still be simplified further, while the other 3 can’t.

How long will it take Birr 500
notka56 [123]

It would take 25 years for Birr 500 to quadruple if invested at a rate of 12% simple interest per annum.

<h3 /><h3>Simple interest formula</h3>

Using the simple interest formula A = P(1 + rt) where

  • P = princial amount = Birr 500,
  • A = final amount = 4P (since it is quadrupled),
  • r = rate = 12% = 12/100 = 0.12 and
  • t = time to quadruple
<h3 /><h3>Finding the time it takes to quadruple </h3>

Since we require t, making t subject of the formula, we have

t = [(A/P) - 1]/r

Substituting the values of the variables into the equation, we have

t = [(A/P) - 1]/r

t = [(4P/P) - 1]/0.12

t = [4 - 1]/0.12

t = 3/0.12

t = 25 years

So, it would take 25 years for Birr 500 to quadruple if invested at a rate of 12% simple interest per annum.
