Step-by-step explanation:

Step 1: Define

Identify

$\displaystyle \left \{ {{g(1) = 50} \atop {g(n) = 8 - g(n - 1)}} \right.$

Step 2: Evaluate

Substitute in x [Function g(n)]: g(2) = 8 - g(2 - 1)
(Parenthesis) Subtract: g(2) = 8 - g(1)
Substitute in function value: g(2) = 8 - 50
Subtract: g(2) = -42

A botanist wishes to estimate the typical number of seeds for a certain fruit. She samples 72 specimens and counts the number of

Oliga [24]

Answer:

99% Confidence interval: (50.9,61.3)

Step-by-step explanation:

We are given the following in the question:

Sample mean, $\bar{x}$ = 56.1

Sample size, n = 72

Alpha, α = 0.01

Sample standard deviation, σ = 16.7

Degree of freedom = n - 1 = 71

99% Confidence interval:

$\bar{x} \pm t_{critical}\displaystyle\frac{s}{\sqrt{n}}$

Putting the values, we get,

$t_{critical}\text{ at degree of freedom 71 and}~\alpha_{0.01} = \pm 2.64$

$56.1 \pm 2.64(\dfrac{16.7}{\sqrt{72}} ) \\\\= 56.1 \pm 5.19\\\\ = (50.91 ,61.29)\approx (50.9,61.3)$

The population of a town is 15,000. It decreases at a rate of 8% per year. In about how many years

Paha777 [63]

Answer:

Step-by-step explanation:

If a population is decreasing by 8% we can multiply the population by 92% (1-.08)

which means we have the following equation

population=15000(.92)ⁿ

where n is the number of years

we want to know when the population will be 10,000 so we write

10,000=15,000(.92)ⁿ

.66667=.92ⁿ

a rule we have is

$n=y^x\\log_yn=x$

which means that

$.66667=.92^n\\=log_{.92}.66667$

compute this and get

4.867

round this up to 5

The height, h, of a plant (in inches) w weeks since it was planted is represented by the equation h=1.2w+3. How many weeks will

alexandr1967 [171]

Answer:

7.5 weeks

Step-by-step explanation:

If you want to find out how long it take for the plant to reach a foot you set up the equation like so:

12=1.2w+3

and solve from there.

12=1.2w+3 Subrtact 3 from both sides

9=1.2w Divide by 1.2 to isolate w

7.5=w Answer is 7.5 weeks
