Answer:
No, it is not possible.
Step-by-step explanation:
A system of linear equations with infinitely many solutions must meet at every single point. That means they have both the same y-intercept and the same slope. If either one of those are different, there cannot be infinitely many solutions.
Answer:
EXPlaIN THIS TO ME cuz i have no idea
Step-by-step explanation:
Parallelogram
so
AE = EC and DE = EB
from here you can find x and y
AE = EC
4x - 2 = x+28
4x - x = 28 +2
3x = 30
x = 10
DE = EB
4y - 7 = y + 14
4y - y = 14 + 7
3y = 21
y = 7
answer: x = 10 and y = 7
Answer:
38.3% of the people taking the test score between 400 and 500
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean and standard deviation , the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question, we have that:
What percentage of the people taking the test score between 400 and 500
We have to find the pvalue of Z when X = 500 subtracted by the pvalue of Z when X = 400. So
X = 500
has a pvalue of 0.6915
X = 400
has a pvalue of 0.3085
0.6915 - 0.3085 = 0.383
38.3% of the people taking the test score between 400 and 500
It is in standard form: y=mx+b
