Answer:

$17.55

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 3%/100 = 0.03 per year,

then, solving our equation

I = 390 × 0.03 × 1.5 = 17.55

I = $ 17.55

The simple interest accumulated

on a principal of $ 390.00

at a rate of 3% per year

for 1.5 years is $ 17.55.

Let X be a normal random variable with mean 40 and standard deviation 2. Find P(X < 28).
Vikki [24]

Answer:

0

Step-by-step explanation:

Given :

Mean = 40 ; Standard deviation = 2

P(x < 28)

Obtain the Zscore :

Z = (x - mean) / standard deviation

P(Z < (28 - 40) / 2))

Z = (28 - 40) / 2

Z = - 12 / 2

Z = - 6

P(Z < - 6) = 0.000000

What is the difference between dash and hyphen
UNO [17]
Hyphens and Dashes. A hyphen joins two or more words together while a dash separates words into parenthetical statements. The two are sometimes confused because they look so similar, but their usage is different. Hyphens are not separated by spaces, while a dash has a space on either side.
