The mean of the samples is 28.25.

The median of the samples is 28.5

The mode of the samples is 35

The standard deviation of the samples is 5.47.

<h3>Mean of the data points</h3>

The mean for highway mileage (mpg) for a sample of 8 different models of a car company is calculated as follows;

mean = (19 + 22, 26, 27, 30, 32, 35, 35)/8

mean = 28.25

<h3>Median of the data points</h3>

The median is calculated as;

median = (27 + 30)/2 = 28.5

<h3>Mode of the data points</h3>

mode = 35 (it has the highest frequency)

<h3>Standard deviation</h3>

∑(x - x')² = (19 - 28.25)²  +  (22 - 28.25)² + (26 - 28.25)² + (27 - 28.25)² + (30 - 28.25)²  + (32 - 28.25)² + (35 - 28.25)² + (35 - 28.25)²

∑(x - x')² = 239.5

S.D = √[(∑(x - x')² / N]

S.D = √(239.5/8)

S.D = 5.47

Is -5/0 undefined. And why is it or why is it not.
xeze [42]
Yes -5/0 is undefined because having 0 of something means you cannot split that 0 into any number so the answer is undefined.

How many solutions does the system have? y=−2x+4
Anna11 [10]

Answer:

There is only one solution and the solution is (0,4).

Step-by-step explanation:

The given system has equations;

y=-2x+4

and

y=x^2-2x+4

We equate the two equations to determine their point of intersection;

x^2-2x+4=-2x+4

\Rightarrow x^2-2x+2x+4-4=0

\Rightarrow x^2=0

\Rightarrow x=0

We put x=0 into the first equation to get;

y=-2(0)+4=4

There is only one solution and the solution is (0,4).

For each of the following, determine the interest rate per compounding period. 1) 12% per year, compounded weekly b) 8% per year
Zarrin [17]

Using compound interest, the rates per compounding period are given as follows:

a) 0.1273 = 12.73%.

b) 0.0833 = 8.33%

c) 0.0617 = 6.17%

<h3>What is compound interest?</h3>

The amount of money earned, in compound interest, after t years, is given by:

A(t) = P\left(1 + \frac{r}{n}\right)^{nt}

In which:

  • A(t) is the amount of money after t years.
  • P is the principal(the initial sum of money).
  • r is the interest rate(as a decimal value).
  • n is the number of times that interest is compounded per year.

The <u>interest rate per compounding period</u> is given as follows:

\left(1 + \frac{r}{n}\right)^n - 1

For item a, the parameters are:

r = 0.12, n = 52.

Hence:

\left(1 + \frac{0.12}{52}\right)^{52} - 1 = 0.1273

For item b, the parameters are:

r = 0.08, n = 104.

Hence:

\left(1 + \frac{0.08}{104}\right)^{104} - 1 = 0.0833

For item c, the parameters are:

r = 0.06, n = 12.

Hence:

\left(1 + \frac{0.06}{12}\right)^{12} - 1 = 0.0617
