Answer:
7.74596669241 (maybe)
Step-by-step explanation:
I havent really done this in a while but I started by making the line into a right triangle and counted how many boxes were inside(6 on the bottom 4 on the side). Then I used the Pythagorean theorem (which is the process of taking the sides and making them squares) < To simplify that explanation (I squared the sides(6 and 4).) so now we are left with 6² + 4² = x². next what you do is simplify your terms. (6² = 36, 4² = 24. 36 + 24 = 60) We have 60 = x² but we aren't don't yet, now we have to remove the square from x. and to do that we have to square root 60 and x² ( squared numbers being square rooted just leaves the regular number.) when square rooting 60 you are left with 7.8≈.
I hope this helps you, like i said its been a while since ive done this.
Answer:
21/40
Step-by-step explanation:
We can make the equation: 48/7 * x = 18/5
After simplifying it: x = 3/5 * 7/8
Answer: x = 21/40
Therefore, the answer is 21/40
Answer:
The preferred p-value among the options offered is 0.001. The reason is because p-value represents the minimum probability of committing the type I error, that is, the probability of rejecting the null hypothesis, with the information contained in the sample, given that this hypothesis is true. The p-value of 0.001 is the lowest value proposed for this probability. Therefore, it supports more evidence that the null hypothesis is false.
Step-by-step explanation:
Answer: b = - a
Step-by-step explanation:
Given that b is located the same distance from 0 as another number a, but in opposite direction.
If b varies directly as a
Then,
b = - ka
Hence the opposite variation or relationship between a and b means they both carry opposite signs
Hence,
b = - a
