Calculate the simple interest paid on a loan of $544 at 3% for three months.

exis [7]

Answer:

Step-by-step explanation:

Answer: interest at the end of 3 months is $4.08

Step-by-step explanation:

The formula for simple interest is expressed as

I = PRT/100

Where

P represents the principal

R represents interest rate

T represents time in years

I = interest after t years

From the information given

T = 3 months = 3/12 = 0.25 years

P = $544

R = 3%

Therefore

I = (544 × 3 × 0.25)/100

I = 408/100

I = 4.08

Which represents a function and why? I'm confused

A function has only one output (y) for every input (x). Easy way to identify a function on a graph is by the vertical line test. Imagine a vertical line going through the function, if the imagined line can go through exactly once, it's a function. (The top one is a function, the bottom is not.)

Calculating conditional probability

Calculating conditional probability

The usher at a wedding asked each of the 80 guests whether they were a friend of the bride or of the groom.

Here are the results:

Bride :29

Groom :30

BOTH : 20

Given that a randomly selected guest is a friend of the groom, find the probability they are a friend of the bride.

P (bride | groom)

Answer:

The probability is $P(B|G) = \frac{2}{3}$

Step-by-step explanation:

The sample size is $n = 80$

The friend of the groom are $G = 30$

The friend of the groom are $B = 29$

The friend of both bride and groom are $Z = 20$

The probability that a guest is a friend of the bride is mathematically represented as

$P(B) = \frac{29}{80}$

The probability that a guest is a friend of the groom is mathematically represented as

$P(G) = \frac{30}{80}$

The probability that a guest is both a friend of the bride and a friend of the groom is mathematically represented as

$P(B \ n \ G) = \frac{20}{80}$

Now

$P(B|G)$ is mathematically represented as

$P(B|G) = \frac{P(B \ n \ G)}{P(G)}$

Substituting values

$P(B|G) = \frac{\frac{20}{80} }{\frac{30}{80} }$

$P(B|G) = \frac{2}{3}$
