Answer:

  • 1.6 hrs took by dale to cover the distance.

Step-by-step explanation:

We have been given that dale is riding his bicycle. He rides at a speed of 9 kilometers per hour for 14.4.

Let's write the data in simplest form.

  • Total distance covered by dale = 14.4 km
  • Speed of bicycle = 9 km/hr

We have to find the time taken by dale to cover the distance.

Here, Time is given by distance / Speed.

Time = Distance/Speed

Time = 14.4/ 9

Time = 1.6 hr

  • Therefore, 1.6 hrs took by dale to cover the distance.

Ronch [10]

Answer:

REQUIRED TEST STATICS IS 35.19

Step-by-step explanation:

total size of sample = 10,000

                                     men                            women

voted                           2777                            3466

did not vote                  1444                             2313

By chi square test we can find the relationship between gender and participation in the election

<em>X^2 = \frac{ N(ad-bc)^2}{(a+c)(b+d)+(a+b)(c+d)}</em>

where

a represent  = 2777, b = 3466, c= 1444, d = 2313, N = 10000

Putting values to get chis square statics

<em>X^2 = \frac{ 10000(2777*2313-3466*1444)^2}{(2777+1444)(3466+2313)+(2777+3466)(1444+2313)}</em>

<em>X^2 = = 35.159</em>

HENCE REQUIRED TEST STATICS IS 35.19
