Answer:
n=601
Step-by-step explanation:
Formula used:
Solution:
Where,
As there is no previous estimate for p
Then, p=0.5
Here on using the table
Also,
E=0.04
p=0.5
Thus,
n=600.2279407
On approximating the value,
n=601
If the 1 were underlined it would be 10,000
If the 6 were underlined it would be 6,000
If the 4 were underlined it would be 400
If the 0 were underlined it would be 0
If the 3 were underlined it would be 3
Answer:
-7±3√6
Step-by-step explanation:
Answer: The price of each small box is $4.8 and the price of each large box is $10.8.
Step-by-step explanation:
Let x = Price of each small box, y= price of each large box.
As per given,
3x+2y= 36 ...(i)
4x+y= 30 ...(ii)
Multiplying 2 to (ii), we get
8x+2y =60...(iii)
Subtract (i) from (iii), we get
5x= 24
x= 4.8
From (ii)
4(4.8)+y= 30
19.2+y=30
y= 10.8
Hence, the price of each small box is $4.8 and the price of each large box is $10.8.
Answer:
y=40-15x
Step-by-step explanation:
Let x represent the number of hours.
We have been given that Dudley travels 30 miles every 2 hours, so distance covered in each hour by Dudley would be:
.
Since Dudley travels 15 km per hour, so distance covered in x hours would be 15x.
We have been given that Dudley wants to cover 40 miles. So we can represent our given information in an equation as:
, where, y represents number of miles he has left to travel, after biking x hours.
