Answer:
0=0
or as separate equations:
y=1/2
X=4y+2
Explanation:
If we solve your system by elimination:
x−4y=2;4x−16y=8 -->
Multiply the first equation by -4,and multiply the second equation by 1.
−4(x−4y=2)
1(4x−16y=8)
Becomes:
−4x+16y=−8
4x−16y=8
Add these equations to eliminate x:
0=0

Answer:
the length of the piece of rope in meters is 22
Step-by-step explanation:
The computation of the length of the piece of rope in meters is shown below:
= 2πr
= 2 × 3.14 × 3.5m
= 21.98
= 22 meters
Hence, the length of the piece of rope in meters is 22
A z score is a standardized score, measuring the number of standard deviations a given score is away from the mean. If the original scores are normal, the z scores will have a standard normal distribution.
Choice b
Answer:
yes another flavor should be in the bag. because the problem stated that there are three different flavor, and only two flavors were mentioned in the problem. the probability of getting the third flavor is 5/7 i guess, because it think the probability of the second flavor was the answer when you added both the numerator and the denominator of 1/3 by 2. like 1/3+2=3/5, so if you added 2 to both the numerator and the denominator of 3/5, you will get 5/7. but i am not so sure about this, i'm sorry in advance.
