Max has $2000: $1000 decreased in value exponentially at a rate of 0.5% annually

Sergio039 [100]

Answer:

$2147.36

Step-by-step explanation:

The first value can be modeled by ...

b1 = 1000·(1 -0.005)^t

After 10 years, that balance is ...

b1 = 1000·0.995^10 = 951.11

The second value can be modeled by ...

b2 = 1000·(1 +0.018/2)^(2t)

After 10 years, that balance is ...

b2 = 1000·1.009^20 = 1196.25

The total of the two investments after 10 years is ...

$951.11 +1196.25 = $2147.36

D) (K<br> If f(x) = x3 and g(x) = 2x + 7, what is g(x)<br> when x = 2?

nadya68 [22]

Answer:

Step-by-step explanation:

g(x) = 2x + 7

Put x as 2 and evaluate.

g(2) = 2(2) + 7

Multiply.

g(2) = 4 + 7

Add the terms.

g(2) = 11

A random sample of 25 fields of spring wheat has a mean yield of 27.6 bushels per acre and standard deviation of 5.69 bushels pe

ale4655 [162]

Answer:

Step 1 z(c) = 2,323

CI = ( 25 ; 30,2 )

Step-by-step explanation:

Normal Distribution:

Sample size n = 25

Sample mean μ = 27,6

Sample standard deviation s = 5,69

CI = 98 % then α = 1 - 0,98 α = 0,02 α/2 = 0,01

From z-table we don´t find z (score) for 0,01 directly, we need to interpolate between z = 2,32 and z = 2,33

For 0,0099 z score is 2,33

for 0,0102 z score is 2,32

Δ 0,0003 0,01

Then by rule of three

for Δ 0,0003 ⇒ 0,01

for Δ (0,01- 0,0102) ⇒ x

0,0003 0,01

0,0002 x

x = 0,0067

then z (score for 0,01) = 2,33 - 0,0067 z(c) = 2,3233

round to three decimal places z(c) = 2,323

Step 2:

CI = μ ± z(c) * s/√n ⇒ 27,6 ± (2,323 * 5,69)/5

CI = 27,6 ± 2,6436

round to one decimal place

CI = 27,6 ± 2,6

CI = ( 25 ; 30,2 )
