Answer:
32 ft²
Step-by-step explanation:
Given the right angle and equal sides, we have a square. The diagonal is the hypotenuse of a right triangle, so we can use the Pythagorean Theorem to calculate the side lengths, or realize that the side lengths Squared will be the area of the square.
c² = a²+b² Since a² equals b², the equation becomes c² = 2a²
8² = 2a²
64/2 = a²
32 = a², the area of the square.
The side lengths of the square are √32
about 5.657 feet. If we square that square root, we get the area of the square, 32 square feet.
Answer:
4.464 ml
Step-by-step explanation:
Given that:
mean (μ) = 5 mm, standard deviation (σ) = 0.4 ml
The z score is a score in statistics used to determine by how many standard deviation the raw score is above or below the mean. If the z score is positive then the raw score is above the mean and if the z score is negative then the raw score is below the mean It is given by:

From the normal distribution table, the 9th percentile (0.09) corresponds to a z score of -1.34

The dye amount that represents the 9th percentile of the distribution is 4.464 ml
Answer:
Step-by-step explanation:
Remark
You can do this with just 1 unknown.
John = x
Tom = 2x
Solution
x + 2x = 27 Combine the left
3x = 27 Divide by 3
3x/3 = 27/3
x = 9
Conclusion
John invited 9
Tom invited 18
Answer: y=2
Step-by-step explanation:
First you would plug in the 9 for x, then you would try to solve for y
