Three different design configurations are being considered for a particular component. There are two possible failure modes for
asambeis [7]

Answer:

No evidence .because the configurations factors and failure mode are independent

Step-by-step explanation:

Determine if there is sufficient evidence to conclude that configuration affects the type of failure

Number of configurations = 3

Number of failures = 4

assuming <em>Pij </em>represents proportion of items in pop i of the category j

H0 : <em>Pij = Pi * </em>Pj<em>,  </em>I = 1,2,-- I,  j = 1,2,---J

Hence the expected frequencies will be

16.10 , 43.58 , 18, 12.31

7.5,  19.37, 8 , 5.47

10.73, 29.05, 12, 8.21

x^2 = 13.25

test statistic = 14.44. Hence the significance level where Null hypothesis will be acceptable will be = 2.5%

jeyben [28]

The formula to calculate the experimental probability is "P(event) = Number of times event occurs/total number of trials"

The expiramental probability should be the fraction "21/47"

The theoretical probability should be the fraction "1/3" because the formula for theoretical probability is the number of favorable outcomes (5 dollar bill) over the total number of possible outcomes (10-dollar bill, one dollar bill, & 5 dollar bill). therefore, there is 1 favorable outcome, and 3 possible outcomes = 1/3.

kiran and clare live 24 mile away from each other along a rail trail. One Saturday the two friends started walking toward each o
scZoUnD [109]

Answer:

11:45\ am

Step-by-step explanation:

Total distance between Kiran and Clare is 24 miles. They started walking at 8.00 am.

Speed of Kiran is 3 miles/hr and speed of Clare is 3.4 miles/hr.

So the relative speed of them is,

=3+3.4=6.4 miles/hr

Both the speed are added as they moving in opposite direction.

We know that,

\text{Relative speed}=\dfrac{\text{Relative distance}}{\text{Time}}

i.e \text{Time}=\dfrac{\text{Relative distance}}{\text{Relative speed}}

Putting the values,

t=\dfrac{24}{6.4}=3.75\ hr=3\ hr\ 45\ min

As they started at 8.00 am, so the time at which will meet will be,

=8+3\ hr\ 45\ min=11:45
