Answer:

Kindly check explanation

Step-by-step explanation:

Given the data :

Car 1 Car 2

214 220

245 221

239 244

224 225

220 258

295 259

Ordered data:

Car 1 : 214, 220, 224, 239, 245, 295

Sample mean = ΣX/ n ; n = sample size = 6

Sample mean = 1437 / 6 = 239.5

Median = 1/2(n+1)th term = 1/2(7) = 3.5th term

Median = (3rd + 4th) /2 = (224 + 239) /2 = 231.5

Sample standard deviation; √(Σ(x - xbar)²/n-1 ) = 29.60 (using calculator)

Car 2 : 220, 221, 225, 244, 258, 259

Sample mean = ΣX/ n ; n = sample size = 6

Sample mean = 1427 / 6 = 237.833

Median = 1/2(n+1)th term = 1/2(7) = 3.5th term

Median = (3rd + 4th) /2 = (225 + 244) /2 = 234.5

Sample standard deviation; √(Σ(x - xbar)²/n-1 ) = 18.21 (using calculator)

Multiply. Write your answer as a fraction in lowest terms.

Step2247 [10]

Answer:

6 4/7

Step-by-step explanation:

Convert any whole numbers to mixed numbers

$\frac{12}{1} \times \frac{23}{42}$

Use fractions formula

$\frac{a \times b}{c \times d} = \frac{e}{f}$

$\frac{12 \times 23}{1 \times 42} = \frac{276}{42}$

Count how many times 276 goes into 42 <em>evenly</em>

<em></em> $= 6\frac{4}{7}$
