ANSWER
The correct answer is B
<u>EXPLANATION</u>
If we analyse the coordinates carefully, you realize there is a mapping of
This is a reflection in the y-axis.
Since the transformation is a reflection, the shape is preserved. Therefore, the image triangle P'Q'R' of triangle
PQR are congruent.
1. The two equations follow the slope-intercept form which y=mx + b. They have the same y-intercept which is equal to 900.
2. Suppose x= 10
Plan Alpha: y=-7x+900=-7(10)+900=830
Plan Foxtrot: y = -17x+900 = -17(10)+900=730
Between the 2 plans, the lower value is 730. Plan Foxtrot is better for reduction of pollution.
3. The city council should choose Plan Foxtrot because the reduction of pollution is much greater. Their goal would be reached faster if they go with faster reduction of pollution.
All the roots of the provided function If f(1) is equal to the zero are -3, -1 and 1.
<h3>What is polynomial?</h3>
Polynomial equations is the expression in which the highest power of the unknown variable is n (n is real number).
The function given in the problem is,
If f(1) = 0
Thus, (x-1) is one of the factor of polynomial. Equate the polynomial equal to the zero, to find other roots as,'
Equate all the groups to zero to find the roots as,
Hence, all the roots of the provided function If f(1) is equal to the zero are -3, -1 and 1.

Answer:
2.5%, 0.125, 1/4
Step-by-step explanation:
Answer:
Step-by-step explanation:
Normally Z scores in a std normal distribution curve lie between -3 and 3 comprising more than 99% of total area.
Any entry outside (-3,3) can be considered as an extreme observation.
Here we have hence a) -4.3 is the most extreme observation.
-------------------------
Given that 84 separates the lowest 75% of the scores from the highest 25% of the scores,
This means 84 is the 75th percentile and similarly 65 is the 25th percentile.
Thus we have 84 has the percentile rank of 75
