A population has a standard deviation of 24. What is the standard error of the sampling distribution if the sample size is 100?
A. 0.48
B. 4.8
C. 0.24
D. 2.4
Answer:
D. 2.4.
Step-by-step explanation:
S.E. = std dev / √N
= 24 / √100
= 2.4.
The standard error of the sampling distribution will be 2.4. Then the correct option is D.
The standard deviation of a statistic's sample distribution, or an approximation of that standard deviation, constitutes the statistic's measurement error (SE).
SE = σ / √n
A population has a standard deviation of 24. Then the standard error of the sampling distribution, if the sample size is 100, is calculated as,
SE = σ / √n
SE = 24 / √100
SE = 24 / 10
SE = 2.4
The standard error of the sampling distribution will be 2.4. Then the correct option is D.
More about the standard error link is given below.

If you draw a line separating the big square from the little square, you have a 12 x 10 large square, and a 5 x 4 smaller square. We know the second dimension of the small square because the large square takes 10ft off of the total length of 4ft.
Calculate both areas separately, then add them together.

The diameter of a circle is 12 miles, what is the length of the 180 degree arc in the simplest form?
9514 1404 393
Answer:
6π ≈ 18.8 miles
Step-by-step explanation:
The full circumference of a 12-mile circle is ...
C = πd
C = π(12 mi)
So, half the circumference of the circle is ...
arc length = 1/2C = (12π mi)/2 = 6π mi ≈ 18.8 mi

Answer:
B
Step-by-step explanation:
A square root can‘t be negative so
x -1 ≥ 0
x ≥ 1
We can say that the domain is
[1 ; +oo)
The function p(x)=[tex]\sqrt{x+1}+2[/tex]. The domain of the function is [1,∞) or {x|x≥1}.
Given that,
The function p(x)=[tex]\sqrt{x+1}+2[/tex]
We have to find the function domain.
What id domain of the function?The sets of all the x-coordinates and all the y-coordinates of ordered pairs, respectively, make up the domain and range of a relation.
The components of a function are its domain and range. Range, Domain, and Function. If a function f: A→ B exists that maps every element in A to an element in B, then A is the domain and B is the co-domain. The representation of an element 'a' under a relation R is given by 'b', where (a,b) R. The range of the function is the set of photos. In general, a function's domain and range are denoted as follows: Domain(f) = {x ∈ R} and range(f)={f(x) : x ∈ domain(f)}.
The domain of the function is [1,∞) or {x|x≥1}.
Therefore, The domain of the function is [1,∞) or {x|x≥1}.

Jenelle invested $17000 in two mutual funds. Fund A earned 4% profit during the first year, while Fund B suffered a 1.5% loss. If she received a total of $460 profit, how much had she invested in each mutual fund?
Jenelle invested $_____ into Fund A.
Jenelle invested $_____ into Fund B.
Answer:
Jenelle invested $ 13,000 in Fund A and $ 4,000 in Fund B.
Step-by-step explanation:
Given that Jenelle invested $ 17000 in two mutual funds, and Fund A earned 4% profit during the first year, while Fund B suffered a 1.5% loss, if she received a total of $ 460 profit, to determine how much had she invested in each mutual fund, the following calculation must be performed:
17000 x 0.04 - 0 x 0.015 = 680
15000 x 0.04 - 2000 x 0.015 = 570
10,000 x 0.04 - 7000 x 0.015 = 295
12500 x 0.04 - 4500 x 0.015 = 432.5
13000 x 0.04 - 4000 x 0.015 = 460
Therefore, Jenelle invested $ 13,000 in Fund A and $ 4,000 in Fund B.

You have 24 seashells and give 8 seashells to your sister. You arrange the rest of the seashells into 4 equal rows. Which steps can you use to find the number of seashells in each row?
Step 1: 24 – 8 = 16
Step 2: 16 × 4 = 64
There are 64 seashells in each row.
Step 1: 24 – 8 = 16
Step 2: 16 ÷ 4 = 4
There are 4 seashells in each row.
Step 1: 24 + 8 = 32
Step 2: 32 ÷ 4 = 8
There are 8 seashells in each row.
Step 1: 8 ÷ 4 = 2
Step 2: 24 – 2 = 22
There are 22 seashells in each row.

Answer:
C. A = 0.5*d1*d2
D. A = bh
Step-by-step explanation:
The area of the rhombus can be found depending on what information is made available to us.
If given the lengths of the two diagonals (d1 and d2) of a rhombus which bisect each other, therefore, the formula for finding the area would be:
A = 0.5*d1*d2
Also, if we are given the height (h) and side (b), the formula to use would be:
A = bh
