Answer:
(-2,2)
Step-by-step explanation:
Looking at your graph, the part were both lines intersect/meet is at point (-2,2). Since (-2,2) is the point of intersection, it is the solution to the equations.
Hope this helps ^-^

<h3>d. 2x³ - 7y³ → 2x³, -7y³ - binomial</h3>
The answer to the question
Answer:
NP = 43
LNO = 137
MNP = 137
Step-by-step explanation:
MNL is a vertical angle to PNO, therefore they are equal
MNL = PNO
MNL = 43 = PNO
MNL and LNO are supplementary angles. They add to 180 degrees
MNL + LNO = 180
43+LNO = 180
Subtract 180 from each side
43-43 +LNO = 180-43
LNO = 137
LNO and MNP are vertical angles. Vertical angles are equal
LNO = MNP
137=MNP
Answer:
Step-by-step explanation:
Data given and notation
represent the sampe size for A
represent the sample size for B
represent the sample deviation for A
represent the sample deviation for B
represent the significance level provided
F test is a statistical test that uses a F Statistic to compare two population variances, with the sample deviations s1 and s2. The F statistic is always positive number since the variance it's always higher than 0. The statistic is given by:
Solution to the problem
System of hypothesis
We want to test if we have the same variation, so the system of hypothesis are:
H0:
H1:
Calculate the statistic
Now we can calculate the statistic like this:
