Answer:
B
Step-by-step explanation:
We can see that
both lines intersects at origin
so, the solution is x=0 and y=0
now, we will check each options
option-A:
![y=2x](https://tex.z-dn.net/?f=%20y%3D2x%20)
![y=-4x](https://tex.z-dn.net/?f=%20y%3D-4x%20)
now, we can set them equal
and then we can solve for x
![-4x=2x](https://tex.z-dn.net/?f=%20-4x%3D2x%20)
![6x=0](https://tex.z-dn.net/?f=%206x%3D0%20)
![x=0](https://tex.z-dn.net/?f=%20x%3D0%20)
now, we can find y
![y=2*0](https://tex.z-dn.net/?f=%20y%3D2%2A0%20)
![y=0](https://tex.z-dn.net/?f=%20y%3D0%20)
so, solution is x=0 and y=0
so, this correct...........Answer
Answer:
Option 3. In step 3, she did not subtract one x from the left side
Step-by-step explanation:
we have the repeating decimal
0.272727...
Convert to fraction number
step 1
Let
x=0.272727...
step 2
Multiply by 100
100x=27.272727...
step 3
Subtract x from 100x
100x-x=27
99x=27
step 4
Find the value of x
x=27/99
therefore
Manda's work is not correct
In step 3, she did not subtract one x from the left side
Answer:
- A. Paired-sample t-test. --- Wilcoxon Signed-Ranks T test
- B. Independent-sample t-test. --- Mann-Whitney U test
- C. One-way ANOVA, independent samples. --- Kruskal-Wallis H test
- D. One-way ANOVA, repeated measures. --- Friedman test
Step-by-step explanation:
- The nonparametric statistics is a branch of statistics, that seeks out the population distribution that is either being distributed freely or specifically.
- Wilcoxon Signed-Ranks T-test is a hypothesis test used to compare the two or pre related columns that can be matched and maybe a repeated measure on a single sample.
- The Mann-Whitney U test is a null hypothesis and states the probability of a random sample of X and Y from the population is greater than the X and that Y is greater than X.
- Kruskal-Wallis H test is a test of one variance analysis and tests that sample originates from the same distribution.
- The Friedman test is used to find treatment across multiple tested attempts. It involves the ranking of the rows and then considering the values of the column.
There are twelve possible combinations. Most of them will seriously mess up the keyboard.
