Area under the curve: find the probability of each of the following, if Z-N(μ=0, σ=1). (Please round any numerical answers to 4 decimal places). a) P(Z 1.48) =
b) P(Z > 1.48)=
c) P(-0.4 2) =
d) P( | Z | >2)=

b.an increase in a causes b to decrease

(a) common ratio in the given sequence is, 3

(b) push ups will do kendall do on the 20th week

step-by-step explanation:

geometric sequence is a sequence of numbers that follows a pattern were the next term is found by multiplying by a constant called the common ratio(r)

(a)

given the sequence: 6 , 18 , 54 , 162 ,

this sequence is geometric sequence where each term is 3 times the previous term.

therefore,

common ratio(r) = 3.

(b)

a formula for nth term of geometric sequence is given by;

,   where r is the common ratio between the successive terms and is the first term,

to find how many push ups will kendall do on the 20th week.

here. n = 20th term.

in the given sequence first term

then;

simplify:

therefore, push ups will do kendall do on the 20th week
