Answer:
x=1,y=3
correct answer is (1,3)
Step-by-step explanation:
We can quickly eliminate y by subtracting one equation from the other
(-2x+y=1)-(-4x+y=-1)
2x=2
x=1
plug x=1 into equation 1
-2(1)+y=1
y=1+2=3
here are the numbers of 15 people ate out last month. 6,5,5,3,5,4,3,6,4,3,6,5,3,7,6 find the modea of this data set

Answer: 3 and 5
Step-by-step explanation: The mode is the number that appears most frequently in a data set.
Although it's optional I recommend writing these integers from least to greatest so it will be easier to see what number occurs most frequently.
Notice that there are two numbers (3 and 5) that appear most often (and the same number of times) which means the data set has two modes. When a data set has two modes, this is called bimodal.
She has totally 10+5+3=18 marbles, so the probability is 10/18=5/9. The complement is (9-5)/9=4/9.
Hope this helped!
Answer:
.
Step-by-step explanation: Given radical expression
.
According to the product property of roots.
![\sqrt[n]{a} \times \sqrt[n]{b} = \sqrt[n]{a \times b}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%7D%20%5Ctimes%20%5Csqrt%5Bn%5D%7Bb%7D%20%3D%20%5Csqrt%5Bn%5D%7Ba%20%5Ctimes%20b%7D)
On applying above rule, we get
![\sqrt[3]{5x} \times \sqrt[3]{25x^2} = \sqrt[3]{5x \times 25x^2}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B5x%7D%20%5Ctimes%20%5Csqrt%5B3%5D%7B25x%5E2%7D%20%3D%20%5Csqrt%5B3%5D%7B5x%20%5Ctimes%2025x%5E2%7D)
5 × 25 = 125 and

Therefore,
![\sqrt[3]{5x \times 25x^2}= \sqrt[3]{125x^3}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B5x%20%5Ctimes%2025x%5E2%7D%3D%20%5Csqrt%5B3%5D%7B125x%5E3%7D)
<h3>So, the correct option would be second option
![\sqrt[3]{125x^3}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B125x%5E3%7D)
.</h3>
