2r-3.1=1.7 solve each equation check your soultion plz help step by step plz
professor190 [17]

2r-3.1=1.7 add 3.1

2r=1.7+3.1 divide by 2 to isolate r

2r/2=4.8/2

r=2.4

check

2(2.4)-3.1=1.7

4.8-3.1=1.7

1.7=1.7

4t+3.5=12.5 sub 3.5

4t=12.5-3.5 divide by 4

4t/4=9/4

t=9/4

check

4(9/4)+3.5=12.5

9+3.5=12.5

12.5=12.5

8m-5.5=10.1 add 5.5

8m=10.1+5.5 divide by 8

8m/8=15.6/8

m=1.95

check

8(1.95)-5.5=10.1

15.6-5.5=10.1

10.1=10.1

Total blood cholesterol level was measured for each of
laiz [17]
<h3>Answer: Mean = 218.9.</h3><h3>Median = 229</h3><h3>Mode = Zero mode.</h3>

Step-by-step explanation:

Given blood cholesterol level was measured for each of 8 adults (in mg/dL) are:

264, 191, 160, 148, 262, 212, 268, 246

In order to find the mean, we need to add all those 8 numbers and divide by 8.

Therefore, mean = \frac{264+191+160+148+262+212+268+246}{8} =\frac{1751}{8} =218.9.

<h3>Mean = 218.9.</h3>

In order to find the median, we need to arrange them in ascending order:

148, 160, 191, 212, 246, 262, 264, 268.

The middle most two values are 212 and  246.

Therefore, median = \frac{212+246}{2} =\frac{458}{2} = 229.

<h3>Median = 229.</h3>

\mathrm{The\:mode\:is\:the\:term\:in\:the\:data\:set\:that\:appears\:the\:most.}

\mathrm{If\:there\:is\:more\:than\:one\:term\:that\:appears\:the\:most,\:then\:there\:is\:no\:mode.}

\mathrm{Count\:the\:number\:of\:times\:each\:element\:appears\:in\:the\:list}

\begin{pmatrix}148&160&191&212&246&262&264&268\\ 1&1&1&1&1&1&1&1\end{pmatrix}

\mathrm{The\:most\:common\:element\:is\:not\:unique,\:so\:there\:is\:no\:mode}

<h3>Therefore, Mode = Zero mode.</h3>

c) account balance: $83,248.32, so interest earned = $3,248.32

_____
The compound interest multiplier for one year is (1 +r/n)^n, where r is the annual rate and n is the number of compoundings in a year. For this problem, you have r=.04, n=4.
