Alex787 [66]

Step-by-step explanation:

Given

mass (m) = 5000 kg

velocity (v) = 100 km/h = 100* 1000/ 3600 = 27.78m/s

Now

Kinetic energy

= 1/2 mv²

= 1/2 * 5000 * 27.78²

Inga [223]

Answer:

Option a is right

Step-by-step explanation:

Given that as part of a research project on student debt at TWU, a researcher interviewed a sample of 35 students that were chosen at random concerning their monthly credit card balance.

Sample average = 2573

Variance = 4252

Sample size = 35

STd deviation of X = $\sqrt{4252} \\=65.21$

Score of student selected at random X=1700

Corresponding Z score = $\frac{1700-2573}{65.201} \\=-13.38$

Rounding of we get Z score = -13.4

option a is right

You can run 3 3/5 miles in 40 minutes. <br><br> What is your unit rate?

fiasKO [112]

Unit rate is how many units of work can you do in 1 unit of time

3 and 3/5=3+3/5=15/5+3/5=18/5

(18/5mi)/40mins
divide by 40
aka times 1/40
(18/5)(1/40)=18/200=9/100=0.9/10=0.09/1
0.09 miles per minute
