Answer:
<h2>One solution.</h2>
Step-by-step explanation:
The given question is
<em>Does the following system have One Solution, No Solution, or Infinite Solutions.
</em>
<em /><em />
<em />
<em />
To solve this system, we just need to multiply the first equation by -1, and then sum those equations.
Then, we use this value to find the other one
As you can observe, the system of equations have a unique solution.
Therefore, the answer is one solution.
Answer:
b
Step-by-step explanation:
to prove if NP is tangent to MN
we could prove if NPM is a right triangle
By pythagorean theorem
a^2+b^2=c^2
where a=MN=33
b=NP=180
c=MP=MQ+QP=152+33=185
so
33^2+180^2=185^2
but
1089+32400 is not equal to 34225
33489 is different from 34225
Answer:
y =x - 2
Step-by-step explanation:
If the slope of the line is 'm', then the slope of the perpendicular to the given line = (opposite reciprocal)
y = -x - 3
Compare with equation of line in slope y-intercept form: y = mx +b
m = -1
This line passes through (2, 0);
Equation of the line in slope - point form:
y - 0 = 1 (x - 2)
y = x - 2
Using Chebyshev's Theorem, considering a standard deviation of 40, we have that at least 75% of the students scored between 360 and 520.
<h3>What does Chebyshev’s Theorem state?</h3>
When we have no information about the population distribution, Chebyshev's Theorem is used. It states that:
- At least 75% of the measures are within 2 standard deviations of the mean.
- At least 89% of the measures are within 3 standard deviations of the mean.
- An in general terms, the percentage of measures within k standard deviations of the mean is given by .
In this problem, considering a standard deviation of 40, we have that:
440 - 2 x 40 = 360.
440 + 2 x 30 = 520.
Within 2 standard deviations of the mean, no information about the distribution, hence, at least 75% of the students scored between 360 and 520.

This equation means that you mustfind the height which in this case is W. ok in order to find w you must do the opposite equation to the output so divide 183 by 212 and the answer is W so W=.9 ( im only in 9th grade so this may or may not be correct)
