Compute the exact interest on $5,870 at 12% if the money is borrowed from June to December of the same year.

yawa3891 [41]

Answer:

The exact interest on $5,870 at 12% is $410.9

Step-by-step explanation:

From the information provided we know that

Principal amount: $5,870

Interest rate: 12% -> 0.12

Time: 7 months (From June to December)

When you know the principal amount, the rate, and the time, the amount of interest can be calculated by using the formula:

$I=P\cdot r\cdot t$

where P is principal, r is the rate of interest and t is the time in years.

We need to convert the 7 months into 1 year.

$7 \>months \cdot \frac{1 year}{12 months} = \frac{7}{12} year$

Now we can use the above formula

$I=P\cdot r\cdot t=5870\cdot 0.12 \cdot \frac{7}{12} \\I = 0.12\cdot \frac{7\cdot \:5870}{12}\\I = 0.12\cdot \frac{20545}{6}\\I = \frac{2465.4}{6}\\I = 410.9$

Therefore the exact interest on $5,870 at 12% is $410.9

Sav [38]

Answer:

0.0006087 (4 sf)

Step-by-step explanation:

Binomial distribution: X ~ B(n, p)

where n is the number of trials and p is the probability of success

Let the random variable X be the number of people with brown eyes

n = 14

p = 40% = 0.4

Therefore, X ~ B(14, 0.4)

P(X ≥ 12) = 1 - P(X ≤ 11)

= 1 - 0.9993913226...

= 0.000608677...

A map has a scale of 1 cm to 16 km.

ra1l [238]

1cm = 16km

1cm • x = 23.1cm
x = 23.1

16km • 23.1 = 369.6km

The real distance is 369.6km.
