The amount of time Ricardo spends brushing his teeth follows a Normal distribution with unknown mean and standard deviation. Ric

Papessa [141]

Let $X$ denote the number of minutes spent brushing his teeth, and let $\mu$ be the mean and $\sigma$ the standard deviation for this distribution.

$\mathbb P(X$

The z-score corresponding to this probability is approximately $z=-0.2533$ , which means

$\dfrac{1-\mu}\sigma=-0.2533\iff\mu-0.2533\sigma=1$

Next, (note the sign change)

$\mathbb P(X>2)=0.02\implies\mathbb P(X\le2)=\mathbb P\left(\dfrac{X-\mu}\sigma\le\dfrac{2-\mu}\sigma\right)=0.98$

The corresponding z-score is approximately $z=2.0538$ , so you have

$\dfrac{2-\mu}\sigma=2.0538\iff\mu+2.0538\sigma=2$

Solving the two equations for $\mu$ and $\sigma$ , you'll find that the mean is approximately $\mu=1.1098$ and the standard deviation is approximately $\sigma=0.4334$ .

Mary Stahley invested $2500 in a 36-month certifi- cate of deposit (CD) that earned 8.5% annual simple interest. When the CD mat

Answer:

$13,916.24

Step-by-step explanation:

First, we need to find the value of the CD at maturity.

A = P(1 +rt) . . . . simple interest rate r for t years

A = $2500(1 +0.085·3) = $2500×1.255 = $3137.50

Now, we can find the value of the account with compound interest.

A = P(1 +r)^t . . . . . rate r compounded annually for t years

A = $3137.50 × 1.18^9 = $13,916.24

The mutual fund was worth $13,916.24 after 9 years.

Nataly_w [17]

$284.99 - 4194.99 = $89.98
$89.98 ÷ 2 = $ 44.99

p = $44.99 for each game.
