The standard error of the sampling distribution is 0.014. The closest option to 0.014 among the answer choices is C. 0.045, but it is not a match. None of the provided answer choices matches the calculated value exactly.
To find the standard error of the sampling distribution, we can use the formula:
[tex]Standard Error = \sqrt{[(sample proportion * (1 - sample proportion)) / sample size]}[/tex]
Given a sample size of 120 and a sample proportion of 0.4, we can calculate the standard error as follows:
[tex]Standard Error = \sqrt{[(0.4 * (1 - 0.4)) / 120]}\\Standard Error = \sqrt{[(0.4 * 0.6) / 120]}\\Standard Error = \sqrt{[0.024 / 120]}\\Standard Error = \sqrt{0.0002}\\Standard Error \approx 0.014[/tex]
Rounded to three decimal places, the standard error is approximately 0.014.

Lia has a ribbon 325 4/5m long. She cuts off a 150 3/5m long piece; then she divided the rest of the ribbon into 3 parts of equal length. Find the length of each part.
Answer:
Each part is 56 11/15 m long.
Step-by-step explanation:
325 4/5 - 150 3/5
= 170 1/5
170 1/5 = 851/5
851/5 / 3
= 851/5 * 1/3
= 851/15
= 56 11/15.
How many times greater is the value of the 6 in 618,923 than the 6 in 27.652
The value of 6 in 618,923 is 1,000,000 or 1 million times greater than that of 6 in 27.652.
What is Place Value?Place value of a digit in a number is defined as the value of that digit according to the position where it stands.
Place value of a whole number of digits from right to left can be expressed as ones, tens, hundreds, thousand, etc.
Place value of a decimal number after the decimal point from left to right can be expressed as tenths, hundredths, thousandths, etc.
The given numbers are 618,923 and 27.652.
Place value of 6 in 618,923 = 6 × 100,000
That is 6 hundred thousands is the place value.
Place value of 6 in 27.652 = 6 × 1/10 = 6 × 10⁻¹
This is at the tenth place.
6 × 100,000 = 6 × 10⁻¹ × 1,000,000
So 6 × 100,000 is 1,000,000 times greater than 6 × 10⁻¹.
Hence the value of 6 in 618,923 is 1,000,000 times greater than the 6 in 27.652.

Javed downloaded from the Internet two files that had a combined size of 696 megabytes. The size of the first file was 290 megabytes, and it took 5 minutes to download. Assuming that the files downloaded at a constant speed, how long did it take for the second file to download?
Answer:
7 minutes
Step-by-step explanation:
The computation of the time taken for downloading the second file is given below:
Given that
The combined size for both files is 696 megabyres
And, the size of the first file is 290 megabytes
So, the size of the second file is
= 696 - 290
= 406
Now for the first file it took 5 minutes to download
So for the second file, it would took
= 406 × 5 minutes ÷ 290
= 7 minutes
Answer:
7 minutes
Step-by-step explanation:
The computation of the time taken for downloading the second file is given below:
Given that
The combined size for both files is 696 megabyres
And, the size of the first file is 290 megabytes
So, the size of the second file is
= 696 - 290
= 406
Now for the first file it took 5 minutes to download
So for the second file, it would took
= 406 × 5 minutes ÷ 290
= 7 minutes
Whats the area of a circle with a circumference of \blueD{50.24}50.24start color #11accd, 50, point, 24, end color #11accd units.
Answer:
[tex]A=200.96\ unit^2[/tex]
Step-by-step explanation:
Given that,
The circumference of the circle, C = 50.24 units
We need to find the area of the circle.
The formula for the circumference of the circle is given by :
[tex]C=2\pi r[/tex]
r is the radius of the circle
[tex]r=\dfrac{C}{2\pi}\\\\r=\dfrac{50.24}{2\times 3.14}\\\\r=8\ units[/tex]
The formula for the area of a circle is given by :
[tex]A=\pi r^2\\\\A=3.14\times 8^2\\A=200.96\ unit^2[/tex]
So, the area of the circle is equal to [tex]200.96\ unit^2[/tex].

Answer:
It has two numbers per turn. The first is 2 and stays the same the whole time. The second number starts as 5, but every time it hits that number, it increases by 1.
Step-by-step:
As we already know, two starts off the turn, so every number on this turn will increase by 2 (6+2=8.)
Now, for this one, we have five, so for this turn we'll increase it by that much (8+5=13).
However, this number won't stay at 5. Instead, it will increase by 1 every time we hit this turn. Let's continue one:
Turn Two = 13+2=15
Turn 5+1 = 6 = 15+6=21
Turn Two = 21+2=23
Turn 6+1 = 7 = 23+7=31
And from there, the pattern would/will continue!
