g Which statement is correct? Group of answer choices A sample size of 1 is never acceptable. Judgment sampling is preferred to systematic sampling. Cluster sampling is useful when strata characteristics are unknown. Sampling without replacement introduces bias in our estimates of parameters.
Answer:
A sample size of 1 is never acceptable
Explanation:
A sample size of 1 is simply not statistically significant enough as to reach close to accurate conclusions based on sample data. Statistical tests using just one data point may not be enough to test data variability. Axrule of thumb or best practice is to have at least 10% sample size from the population. It is advised to have at least a sample size of 100 sayvpopulation is 1000 to be able to reach more valid conclusions from sample data.

a and b
Step-by-step explanation:
parallel lines are lines that do not intersect each other
find the measure of m
Answer:
m=42
Step-by-step explanation:
because all straight line equal 180, we can find angle C
180-98=82
now, all triangles add up to 180. If we add up all the values we can find x
82+6x+8+5x+2=180
92+11x=180
11x=88
x=8
Now, just plug the variable into the angle measure
5(8)+2
40+2
42

Step-by-step explanation:
Hey there!
“ (x⁴)³ ”
(x⁴) = x⁴ • x⁴ • x⁴
x⁴ = (x • x • x • x) * (x • x • x • x) * (x • x • x • x)
Number of x’s is 12
3 • 4 = 12, right?
Answer: x¹² ☑️

Aaron has between 100 and 110 baseball cards in his collection.If he counts his cards 2 at a time,he has 1 card left over.If he counts his cards 5 at a time,he has 2 cards left over . How many cards are in Aaron's collection ?
Answer:
110
Step-by-step explanation:
Answer:
107 cards
Step-by-step explanation:
So if you skip count by 5 up to one hundred, and then add 2, it's still and even number which the skip counting by 2 says won't work. So then skip count by 5 up to 105 and add 2 to get 107. Hope that makes sense! :)

7 divided by 653 long division please explain
n+0.5(n-1)=7 what is the answer
Answer:
n= 5
Step-by-step explanation:
n + 0.5(n-1) = 7
n + 0.5n - 0.5 = 7
1.5n = 7 + 0.5
1.5 n = 7.5
n = 7.5 × 10/1.5 × 10
n = 75/15
n = 5 ( Answer)

What is the best way to describe the solution of this system of equations?
2x - 5y = 8
5y = -2x + 8
There are infinitely many solutions
There is one solution (4,0).
There are no solutions of the system.
There is one solution (0,4).
Answer:
There is one solution (4,0).
Answer:
x = 4 and y = 0
:-))
Step-by-step explanation:
2x - 5y = 8
x = 8 + 5y .........(1)
2
5y = -2x + 8
x = 8 - 5y ........(2)
2
get from 1 and 2
8 + 5y = 8- 5y
2 2
or, 10y = 0
or, y = 0
put the value of y in 1
x = 8 + 0
2
or, x = 4

jun uses a 20%-off coupon to by the ingredents for congee. she spends $40. what is the regular price r of the ingredeints before the discount
Answer:
$50
Step-by-step explanation:
Make the equation where x is the original price:
x - 0.2x = 40
Combine like terms
0.8x = 40
Divide both sides by 0.8
40/0.8 = 50
whats the trans ___ and reflection ___
Given that,
A graph.
To find,
The trans and the reflection.
Solution,
When we slide a figure in any direction, it is called translation or trans.
In this case, option 1 is trans such that ABCD and A'B'C'D' are in same line.
When we flip a figure over a line, it is called reflection.
In this case, option Option 3 is reflection such that ABCD and A'B'C'D' are in opposite direction.
8. The value of 6 quarters is what percent of the value of a dollar? Do not units (%) in your answer.
Answer:
150%
Step-by-step explanation:
4 quarters = %1.00 = 100% and 2 quarters = $0.50 = 0.50%
100% + 50% = 150% or $1.50
tan²Ф+sec²Ф=3
can someone solve this by finding all answers as the nearest whole degree
Recall that
tan²(x) + 1 = sec²(x)
for all x ≠ (2n + 1) 90°, where n is any integer. (That is, whenever x isn't an angle that is an odd multiple of 90°.)
Then
tan²(Φ) + sec²(Φ) = 3
tan²(Φ) + (tan²(Φ) + 1) = 3
2 tan²(Φ) + 1 = 3
2 tan²(Φ) = 2
tan²(Φ) = 1
tan(Φ) = ±√1
tan(Φ) = 1 or tan(Φ) = -1
Φ = tan⁻¹(1) + n 180° or Φ = tan⁻¹(-1) + n 180°
Φ = 45° + n 180° or Φ = -45° + n 180°
The first family of solution is the set of angles
{…, -315°, -135°, 45°, 225°, 405°, …}
and the second family is the set
{…, -405°, -225°, -45°, 135°, 315°, …}
(showing the solutions for n = -2 to n = 2)
You can condense the solution set into one family by noticing each angle is 45° plus some multiple of 90°, so that
Φ = 45° + n 90°
If you're looking for solutions in a given range, such as 0 ≤ Φ < 360°, then
Φ = 45°, 135°, 225° or 315°

Answer:
f(-1) = -1
Step-by-step explanation:
x = -1 falls in the middle segment, where -2 < x < 2. So, the applicable function definition is ...
f(x) = -2x -3
f(-1) = -2(-1) -3 = 2 -3
f(-1) = -1
