1. Work out the speed of a car travelling:

Norma-Jean [14]

Answer:

10m/s,15m/s,20m/s,5m/s

Step-by-step explanation:

Speed = distance / time

a) distance = 100m , time = 10s

Speed = distance / time

Speed = 100m/10s

Speed = 10m/s

b) distance = 300m , time = 20s

Speed = distance / time

Speed = 300m/20s

Speed = 15m/s

c) distance = 700m , time = 35s

Speed = distance / time

Speed = 700m/35s

Speed = 20m/s

d) distance = 1000m , time = 200s

Speed = distance / time

Speed = 1000m/200s

Speed = 5m/s

If a certain machine makes electrical resistors having a mean resistance of 40 ohms and a standard deviation of 2 ohms, what is

Anna71 [15]

Answer:0.0668

Step-by-step explanation:

Given

mean of sample $\mu =40$

Standard deviation $\sigma =2$

For $n=36$ sample

Random variable $Z=\frac{X-\mu }{\frac{\sigma }{\sqrt{n}}}$

For combined resistance of 1458 ohm mean resistance of $\mu =\frac{1458}{36}=40.5$

$P(40.5$

$=P(\frac{40.5-40}{\frac{1}{3}}$

$=P(1.5$

$=1-P(Z\leq 1.5)$

$=1-0.9332$

$=0.0668$
