Answer:  (92, 128)

Step-by-step explanation:

According to the Empirical rule,

If the population is normallly distributed, then 95% of the population lies within 2 standard deviations from the mean.

Given: Mean = 110

Standard deviation = 9

The interval of systolic blood pressures represent the middle 95% of males:

(110-2(9), 110+2(9))

= (110-18, 110+18)

= (92, 128)

Hence, the interval of systolic blood pressures that represent the middle 95 % of males =  (92, 128)

3* (36 - 5x)

Step-by-step explanation:

The total area of the flower garden is equal to the surface of the rectangle that encloses the flowers border and the sitting area minus the area of the sitting area.

Rectangle area

Three flower segments height ----  9  feet

4 flower segments length  ----------- 12 feet

Rectangle area = 12*9 ft^2  = 108 ft^2

Sitting area

Sitting area = 3x*5 = 15x

Area of the flower border (A_flwb)

A_flwb = 108 ft^2 - 15x = 3* (36 - 5x)
