What is the next number in this geometric sequence? -3.24, 9.72,-29.16, 87.48,
A. 262.44
B. 174.96
C.-262.44
D. -174.96

C. -262.44

Step-by-step explanation:

-3.24, 9.72,-29.16, 87.48

-3.24*-3= 9.72, 9.72*-3= -29.16, -29.16*-3= 87.48

the rule for this sequence is multiplying by -3

87.48*-3= -262.44

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.
