The cashier service time at the local branch of the Rivertown bank has an exponential distribution with a mean of 2.5 minutes. W
aleksandrvk [35]

Answer: d. .2474.

Step-by-step explanation:

Given : The cashier service time at the local branch of the Rivertown bank has an exponential distribution with a mean of 2.5 minutes.

The cumulative distribution function for exponential distribution is :-

P(X\leq x)= 1-e^{-\frac{x}{\lambda}}  

, where \lambda = Mean of the distribution.

The probability that the service time is between 2 and 4 minutes will be :

P(2\leq X \leq 4)=P(X\leq4)-P(X\leq 2)\\\\= (1-e^{\frac{-4}{2.5}})-(1-e^{\frac{-2}{2.5}})\\\\=e^{\frac{-2}{2.5}}-e^{\frac{-4}{2.5}}\\\\=0.449328964117-0.201896517995\\\\=0.247432446123\approx0.2474

Hence, the correct option is d. .2474.

Find the missing value. Show your work. please
Sophie [7]
#1
sin(51^o)= \frac{y}{12} \ \ \to \ \ y=12*sin(51^o)=12* 0.7771 \approx 9.33

#2
\theta=arccos( \frac{5^2+13^2-12^2}{2*5*13}) = arccos( \frac{25+169-144}{130})=arccos( \frac{50 }{130})= \\ \\ arccos(0.3846) \approx67.4^o

#3
tan(13^o)= \frac{x}{24} \ \ \to \ \ x=24*tan(13^o)=24* 0.2309 \approx 5.54

#4
sin(20^o)= \frac{10}{x} \ \ \to \ \ x= \frac{10}{sin(20^o)} = \frac{10}{0.342}  \approx 29.24

The cake store is having a 25\%25% off sale on all of its cakes. If the cake you want regularly costs \$9$9, how much would you
Ivanshal [37]

Answer:

You would save $2.25.  

Step-by-step explanation:

In order to find discount on an item, you need to multiply the discount by the original amount of the item.  In this case, the cake you want regularly costs $9.  If the sale includes a 25% discount, then you need to first convert your percentage to a decimal by dividing by 100:

\frac{25}{100} =0.25

You can then take this amount multiplied by the original cost of the cake to get your discount:

0.25 x 9 = 2.25, so you would save $2.25 with the discount and pay only $6.75 for the cake you want.
