A certain forest covers an area of 2000 km. Suppose that each year this area decreases by 3.75%. What will the area be after Il years?
Use the calculator provided and round your answer to the nearest square kilometer.

Exponential decay formula is Total = starting value x (1- percentage)^ time

Total = 2000(1- 0.0375)^11

Total = 2000(0.9625)^11

Total = 1313.524 km

Rounded to nearest km = 1314 km

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.

step-by-step explanation:

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
