A research lab is observing the growth of a new strain of typhoid bacteria 10 points in an agar dish. The initial area occupied by the bacteria is two square
millimeters. In previous experiments with typhoid, scientists observed
the bacteria will grow unrestricted by 25% each week. How much will the
bacteria grow given 10 weeks, if the bacteria grow unrestricted? *
23.3 square millimeters
14.9 square millimeters
18.6 square millimeters
11.9 square millimeters

how many players are there?

step-by-step explanation:

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.
