yawa3891 [41]

Answer:

Step-by-step explanation:

a ) The worth of Jean-Claude's gnome after 1 year

= 80000 x 1.02

= £81600

b ) common ratio of geometric progression

= 81600 / 80000

= 1.02

c ) worth after 10 years

= 80000 x 1.02¹⁰

= 80000 x 1.21899

= £97519.55

d )

120000 = 80000 x $1.02^k$

1.5 = $1.02^k$

ln1.5 = k ln 1.02

k = ln 1.5 / ln 1.02

= .4054 / .0198

= 20.47 years .

Pete took a sample of moviegoers to see how many are seeing a comedy. Sample size: 175 Number seeing a comedy: 42 Population: 1,

Anastaziya [24]

Answer: Part A : c = n.p

Part B = 366 moviegoers

Step-by-step explanation: In part A, to predict the number of moviegoers, we have to find the proportion of the sample that does the activity, which will called p. Since p is a percentage, to determine how many moviegoers are seeing a comedy, you multiply it by the sample size, n.

Therefore: c = n.p

For part B, based on the the sample:

p = $\frac{42}{175}$ = 0.24

The total population is given: 1,525

c = 0.24.1,525

c = 366

Based on the sample, 366 people are seeing a comedy.
