On a blueprint, a rectangular room 15 ft by 14 ft has a semicircular sitting area attached with a diameter of 14 ft. What is the total area of the room and the sitting area?
Use 3.14 for a
15 ft
14 ft
square feet
Pls help asap

Step-by-step explanation:

14*15=210ft²

14/2=7

7*π= 21.991(3dp)  21.991/2= 10.996(3dp)

10.996+210=220.996ft²(3dp)

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
