Answer:
2100
Step-by-step explanation:
28.34 rounds to 30
We look at the 8 which is greater than 5 and rounds the 2 to 3
69.72 rounds to 70
We look at the 9 which is greater than 5 and rounds the 6 to 7
30*70
2100
Answer:
Step-by-step explanation:
Answer:
Sample mean = 7.1
Margin of error = 0.465
Step-by-step explanation:
Formula for confidence interval is;
CI = x¯ ± zE
Where;
x¯ is sample mean
z is critical value at confidence level
E is margin of error.
z for 99% Cl is 2.58
We are told the CI is 5.9 to 8.3.
Thus;
5.9 = x¯ - 2.58E - - - - (1)
8.3 = x¯ + 2.58E - - - - (2)
Add both equations together to get;
14.2 = 2x¯
x¯ = 14.2/2
x¯ = 7.1
Put 7.1 for x¯ in eq 1 to get;
5.9 = 7.1 - 2.58E
7.1 - 5.9 = 2.58E
E = 1.2/2.58
E = 0.465

Question:
How many tons are equal to 36,000 pounds?
Answer:
<h2><u><em>
18 tons </em></u></h2>
Step-by-step explanation:
<em>To convert a pound measurement to a ton measurement, divide the weight by the conversion ratio.</em>
<em />
<em>Since one ton is equal to 2,000 pounds, you can use this simple formula to convert:</em>
<em />
<em>tons = pounds ÷ 2,000</em>
<em>The weight in tons is equal to the pounds divided by 2,000.</em>
<em />
<em>And you could multiply 2,000 by 18 and get the answer 36,000</em>
<em />
<em />

Answer: 346.19cm²
Step-by-step explanation:
π= 3.14
Divide 21 (the diameter) by 2 to get the radius( it 's half of the diameter). so the radius is 10.5
Area= πr²
= 3.14x10.5x10.5
= 346.185
So next round up the value you got to the nearest tenth, so when u round up to the nearest tenth you get 346.19
