Given:
standard deviation = 4.3%
sample size = 15
mean = 26.4%

error = σ/√n

error = 4.3% / √15

error = 4.3% / 3.873

error = 0.0111

0.0111 x 100% = 1.11%

A rectangular field is enclosed by 360 feet of fencing. What is the length, in feet, of the field if it’s length is 6 feet more

Orlov [11]

Answer:

The Field's length is 93ft

Step-by-step explanation:

P=2L+2w

360=2(w+6)+2w

360=2w+12+2w

360=4w+12

348=4w

348/4=w

87=w

L=w+6

L=87+6

L=93

PSYCHO15rus [73]

Answer:

The goat population reaches 1000 in 12.4 years

Step-by-step explanation:

After t years, the number of goats is given by

$N = N_0e^{bt}$

where $N_0$ is the initial number of goats and b is the per capita growth rate.

From the question,

$N_0 = 2$
b = 0.5
N = 1000

$1000 = 2e^{0.5t}$

$e^{0.5t} = 500$

$0.5t = \ln 500 = 6.214$

$t = \dfrac{6.2}{0.5} = 12.4$
