Uma pessoa realizou uma compra que foi financiada em três parcelas mensais e iguais a R$ 350,00, o financiamento foi realizado s

lisabon 2012 [21]

Answer: Amount of purchase would be $393.70.

Step-by-step explanation:

One person made a purchase that was financed in three monthly installments and equal to $ 350.00, the financing was made at the compound interest rate of 48% a.a. Determine the amount of the purchase.

Since we have given that

Principal = $350.00

Rate of compounded monthly = 48%

Number of months = 3

So, the amount of purchase would be

$Amount=350(1+\dfrac{0.48}{12})^3\\\\Amount=350(1+0.04)^3\\\\Amount=350(1.04)^3\\\\Amount=\$393.70$

Hence, Amount of purchase would be $393.70.

Answer:

C. d = 24g

Step-by-step explanation:

The problem boils down to determining the ratio between d and g. That is, for some equation ...

d = k·g

we want to determine the value of k. Solving the equation for that value, we find ...

k = d/g

So, we need only to read a point from the graph with sufficient accuracy to determine a good estimate for k.

(gallons, miles) = (g, d) = (5, 120) is a suitable point

Then ...

k = d/g = 120/5 = 24

The equation is d = 24g.

Answer:

Option E) 61.6

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 100 bushels per acre

Standard Deviation, σ = 30 bushels per acre

We assume that the distribution of yield is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

P(X>x) = 0.90

We have to find the value of x such that the probability is 0.90

P(X > x)

$P( X > x) = P( z > \displaystyle\frac{x - 100}{30})=0.90$

$= 1 -P( z \leq \displaystyle\frac{x - 100}{30})=0.90$

$=P( z \leq \displaystyle\frac{x - 100}{30})=0.10$

Calculation the value from standard normal table, we have,

$P(z$

$\displaystyle\frac{x - 100}{30} = -1.282\\x = 61.55 \approx 61.6$

Hence, the yield of 61.6 bushels per acre or more would save the seed.
