Answer:
I think system 4 has no solution
Step-by-step explanation:
I'm sorry if you get it wrong
When you think of slope intercept form we think of Y=mx+b
m=slope and b = intercept
So all you do is solve for Y in your given equation.
Im going to guess the equal sign because you didn't include it. I can fix the answer is I was wrong.
3y-15=6x (add 15 to both sides)
3y=6x+15 (divide by 3)
y=2x+3 (final answer)
Answer:
2w+5=30
Step-by-step explanation:
Two times the number(w) PLUS 5 is equal to 30. That means that you multiply w by 2, add 5, and that is equal to 30.
Answer:
-2.
Step-by-step explanation:
f(0) = 0^2 + 8(0) - 2
= -2.
Answer:
D. No, because the sample size is large enough.
Step-by-step explanation:
The central limit theorem states that "if we have a population with mean μ and standard deviation σ and take sufficiently large random samples from the population with replacement, then the distribution of the sample means will be approximately normally distributed. This will hold true regardless of whether the source population is normal or skewed, provided the sample size is sufficiently large".
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
If the sample size is higher than 30, on this case the answer would be:
D. No, because the sample size is large enough.
And the reason is given by The Central Limit Theorem since states if the individual distribution is normal then the sampling distribution for the sample mean is also normal.
From the central limit theorem we know that the distribution for the sample mean
is given by:
If the sample size it's not large enough n<30, on that case the distribution would be not normal.
