Step-by-step explanation:
Rs 720
Cost of 1 m of cloth = 450/5= Rs 90
Cost of 8 m of cloth= 90*80= Rs 720
Answer:
The degrees of freedom are given by:
The significance level is 
and then the critical value can be founded in th chi square table we need a quantile that accumulates 0.05 of the area in the right tail of the distribution and for this case is:
And if the chi square statistic is higher than the critical value we can reject the null hypothesis in favor of the alternative.
Step-by-step explanation:
We have the followign system of hypothesis:
Null hypothesis: 
Alternative hypothesis:

Three hundred and nine thousand and seventeen
a) value of x:
ZX =(10x+9)°
122°=( 10x+9)
122 - 9= 10x
113= 10x
x = 113/10= 11.3 °
so answer is = 11.3°
b) measure of Arc XZ :
formula to find Arc= © angle÷360 x 2πr
A = 122÷360 x 2πr
A = 61/180x 2πr
A = 0.3388x2πr
A= 0.6776πr
Answer:
900 in3
Step-by-step explanation:
When you multiply each of the dimensions you get 900 and since you are measuring volume, which has three dimensions, you would add "in3" at the end.
