Answer: 471
Step-by-step explanation:
Given : The population standard deviation is estimated to be $500.
i.e . 
If a 97 percent confidence interval is used and an interval of $100 is desired.
i.e. Margin of error = half of interval
i.e. E= 
Significance level : 1-0.97=0.03
Critical value for 97% confidence interval : 
Formula for sample size :
Hence, at-least 471 cardholders should be sampled.
Diagonals of rhombus are perpendicular
area is (1/2)*d1 * d2 where d1 and d2 are the diagonal lengths
draw the diagonals on your rhombus and you will see a 30-60-90 triangle and then figure
sides will be 6 , 6√3 . 12
so d1 is 2*6 = 12
and d2 is 2*6√3 = 12√3
and area = (1/2)*12*12√3
= 72√3 square cm.
Answer:
0.08 ounce
Step-by-step explanation:
If the size of Tania's reaction is proportional to the amount of water used, then she can reduce the reaction size to 0.1 of its previous value by reducing the quantity of water to 0.1 of its previous value:
0.1 × 0.8 oz = 0.08 oz
The size of Tania's reaction may depend on other factors, so changing the amound of water may have no effect whatever. If water serves as a damper on the reaction, Tania may need to increase the amount of water used.
We do not have enough information to determine an appropriate answer to this question.
Answer:
equation 1 has no solution
Step-by-step explanation:
when you compare each of the equations, all the equations gives a correct answer with the exception of equation 1
