**Answer:**

3(4+5)=27

**Step-by-step explanation:**

**Answer:**

The height of the scale model is of 91.14 cm.

**Step-by-step explanation:**

Scale problems are solved by **proportions**, using rule of three.

**A scale model of a building has a scale of 3 : 79.**

This means that 3m on the drawing represent 79m of real height.

**The height of the real building is 24 m.**

3m - 79m

xm - 24m

Applying cross multiplication

**In centimeters:**

Multiplying by 100:

0.9114*100 = 91.14 cm.

A grocery store purchases cantaloupes from two warehouses, A and B. The

distribution of the diameters from Warehouse A is approximately normal with a

mean of 120 mm and standard deviation of 6 mm.

(a) For a cantaloupe selected at random from Warehouse A, what is the

probability that the cantaloupe will have a diameter greater than 127 mm?

A randomly selected cantaloupe from Warehouse B has the probability of 0.763

that it will have a diameter greater than 127 mm. The grocery store purchases

40% of their cantaloupes from Warehouse B.

(b) For a cantaloupe selected at random from the grocery store, what is the

probability that the cantaloupe will have a diameter greater than 127 mm?

(c) If the randomly selected cantaloupe's diameter is greater than 127 mm, what

is the probability the cantaloupe came from Warehouse B?

No they have different lengths.
