I found the same question on the internet and their answer is $9.76, which is obviously not in your choices. They deducted both given interest rates before multiplying it to the emergency fund amount and dividing it by 12 months.

4.57%−3.5%
=1.07%
(0.0107×10,943.89)÷12
=9.76

Another possible answer is $22.96 using 30 days / 365 days in a year.

Savings: 10,943.89 x (1/4) x 3.5% x (30/365) = $7.87
CD: 10,943.89 x the remainder (3/4) x 4.57% x (30/365) = $30.83

The difference between the two values: 30.83 - 7.87 = $ 22.96: so the first choice (I'm not so sure though)

Assume that X is Normal with mean $ 240 and standard deviation $60 . the probability that , in a randomly selected week , Dan wi

enyata [817]

Answer:

The probability of Dan making less than $255 is 0.5987 or 59.87%

Step-by-step explanation:

Given that:

Mean = μ = $240

SD = σ = $60

We have to find the probability that Dan will make less than $255

First of all, we have to find the z-score of 255

z-score is denoted by z and is given by the formula

$z = \frac{x-mean}{SD}$

Here,

x = 255

Putting the values

$z = \frac{255-240}{60}\\z = \frac{15}{60}\\z = 0.25$

Now we have to look at the z-score table to find the probability of 0.25

P(x<255) = 0.5987

Converting into percentage

59.87%

Hence,

The probability of Dan making less than $255 is 0.5987 or 59.87%
