I would say somewhere between 1 and 2 feet.
Answer:
And rounded up we have that n=31
Step-by-step explanation:
First we need to find the critical value for the margin of error desired. The confidence level is 0.95 so then the significance is and the critical value for this case would be:
The margin of error for the proportion interval is given by this formula:
(a)
And on this case we have that and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)
The estimated proportion for this case is . And replacing into equation (b) the values from part a we got:
And rounded up we have that n=31
Answer:
D.) 4m, 11m, 9m
Step-by-step explanation:
According to the Triangle Inequality Theorem, the sum of any two sides of a triangle must be larger than the third side in order to form a triangle. Using the two shortest sides, you can find the sum and check to make sure it is larger than the third:
3m + 3m = 6m NOT greater than 6m
4m + 7m = 11m NOT greater than 12m
5m + 3m = 8m NOT greater than 9m
4m + 9m = 12m YES greater than 11m
Answer:
30 = 9x + 7
Step-by-step explanation:
The total weight of the bundle = 30 pounds
The weight of the bricks = x pounds
But he carried 9 bricks = 9x pounds
He also carried additional 7 pounds of concrete block.
An equation to show the total weight he carried is
30 pounds = (9x + 7) pounds
Since 9x represents the total weight of the bricks he carried
7 represents the weight of the concrete block
And 30 pounds represents the total weight of everything he carried.
