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.

Answers

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.

There is one solution (0,4).

Answers

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

Find the equation of the line with m = 2 and goes through (-4,5).PLEASE HELP

Answers

The Equation is y=+5
Why:

You want to find the equation for a line that passes through the point (-4,5) and has a slope of .
First of all, remember what the equation of a line is:
y = mx+b
Where:
m is the slope, and
b is the y-intercept
To start, you know what m is; it's just the slope, which you said was . So you can right away fill in the equation for a line somewhat to read:
y=x+b.
Now, what about b, the y-intercept?
To find b, think about what your (x,y) point means:
(-4,5). When x of the line is -4, y of the line must be 5.
Because you said the line passes through this point, right?
Now, look at our line's equation so far: . b is what we want, the 0 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the the point (-4,5).
So, why not plug in for x the number -4 and for y the number 5? This will allow us to solve for b for the particular line that passes through the point you gave!.
(-4,5). y=mx+b or 5=0 × -4+b, or solving for b: b=5-(0)(-4). b=5.

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! :)

tan²Ф+sec²Ф=3


can someone solve this by finding all answers as the nearest whole degree

Answers

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°

It can go 631 miles on a full rank of gas

Answer:

The answer is 630 miles using a 30 gallons tank.

Step-by-step explanation:

Well this question is incomplete, but if we are trying to find how many miles can 30 gallons give then the answer would be 630.

Why? Well since 21 miles = 1 gallon then 630 miles = 30 gallons.

Because 21 multiplied by 30 = 630.
