In order to find the distance covered in 1 minute, we need to divide distance covered 2 1/6 miles by 20 minutes.We are given : Ariel swims 2 1/6 miles in every 1/3 hour.
Let us convert 1/3 hour into minutes.
There are 60 minutes in an hour.
Therefore, 1/3 hours = 60 × 1/3 = 20 minutes.
So, we could say, "Ariel swims 2 1/6 miles in every 20 minutes".
2 1/6÷ 20 = 13/6 ÷ 20.
Let us convert division sign into multiplication and flip 20 to 1/20.
We get
<h3>13/6 × 1/20 = 13/120 miles in 1 minute.</h3><h3>In decimal 0.11 mile in 1 minute.</h3>

Hey there, Lets solve your question together
Question - <span>What is 400 in Expanded form ?
</span>
We know that expanded form is a spread out way to write a number by showing the value of each individual digit that contributes<span> to make the full number.
</span>
Lets use an example to show expanded form
Number - 4,265
= 4 x 1,000 + 2 x 100 + 6 x 10 + 5 x 1
Now lets solve for the number 400 in expanded form.
The number "4" is in the hundreds place
The number "0" is in the tenths<span> place
</span>
<span>The number "0" is in the One's place
</span>Therefore 400 in expanded form is 400+00+0.
<span> Hope this helps </span>
Answer:
CI = 29.8 ± 3.53
Critical value is z = 2.58
Step-by-step explanation:
First of all let's find margin of error. It is given by the formula;
ME = zσ/√n
We are given;
Standard deviation; σ = 3.62
Sample size; n = 7
Mean; x¯ = 29.8
Now, z-value for 99% Confidence level is 2.58
Thus;
ME = (2.58 × 3.62)/√7
ME = 3.53
CI is written as;
CI = x¯ ± ME
CI = 29.8 ± 3.53
Critical value is z = 2.58
