3 gallons would best describe the amount of water in a bucket.
Answer:
B
Step-by-step explanation:
Pythagorean theorem:
6^2 + (4/2)^2 = x^2
36 + 4 = x^2
40 = x^2
x = =
Answer is B
<span>Simplifying
2x + 6 = 4x + -2
Reorder the terms:
6 + 2x = 4x + -2
Reorder the terms:
6 + 2x = -2 + 4x
Solving
6 + 2x = -2 + 4x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4x' to each side of the equation.
6 + 2x + -4x = -2 + 4x + -4x
Combine like terms: 2x + -4x = -2x
6 + -2x = -2 + 4x + -4x
Combine like terms: 4x + -4x = 0
6 + -2x = -2 + 0
6 + -2x = -2
Add '-6' to each side of the equation.
6 + -6 + -2x = -2 + -6
Combine like terms: 6 + -6 = 0
0 + -2x = -2 + -6
-2x = -2 + -6
Combine like terms: -2 + -6 = -8
-2x = -8
Divide each side by '-2'.
x = 4
Simplifying
x = 4</span>
Answer:
460 is part of the confidence interval, which means that we cannot say that there is significant evidence that the mean mathematics SAT score for entering freshmen class is greater than 460
Step-by-step explanation:
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Z-table as such z has a p-value of .
That is z with a pvalue of , so Z = 2.575.
Now, find the margin of error M as such
In which is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 436 - 27.4 = 408.6.
The upper end of the interval is the sample mean added to M. So it is 436 + 27.4 = 463.4.
460 is part of the confidence interval, which means that we cannot say that there is significant evidence that the mean mathematics SAT score for entering freshmen class is greater than 460
