I hope I read it correctly and address as such.
Anywho, this is how my teacher taught me to deal with a question like that. Basically just break up the polynomial on top and divide each part separately by the monomial denominator.

Heights of certain plants at a nursery are normally distributed with a mean of 52.5 centimeters and a standard deviation of 7.2

telo118 [61]

Answer:

The correct option is;

69 cm

Step-by-step explanation:

The z-score, or standard score is a measure of how far a data is from the mean

The z-score, is given by the relation;

$z = \dfrac{x- \mu}{\sigma}$

Z = Standard score

x = Value observed

μ = The mean height of the plants = 52.5 cm

σ = Standard deviation = 7.2 cm

Given that the z-score = 2.25, we have;

$2.25 = \dfrac{x- 52.5}{7.2}$

Therefore, x = 7.2 × 2.25 + 52.5 = 68.7 cm ≈ 69 cm

Therefore, the minimum required height for this type of plant to be displayed in the main lobby is 69 cm.
