Answer:

The whole price at electronics store is $338.58

Step-by-step explanation:

Given as :

The markup percentage = d = 34%

The retail price = m.p = $513

Let  The wholesale price = $ s.p  

<u>Now, According to question</u>

markup percentage = \dfrac{m.p - s.p }{m . p} × 100

Or, d =  \dfrac{m.p - s.p }{m . p} × 100

Or, 34 = \dfrac{513 - s.p }{513} × 100

Or,  \dfrac{34 }{100} = 1 -  \dfrac{ s.p }{513}

Or,  \dfrac{ s.p }{513} = 1 -   \dfrac{34 }{100}

Or, \dfrac{ s.p }{513} =  \dfrac{100 - 34 }{100}

Or, \dfrac{ s.p }{513} =  \dfrac{66 }{100}

Or, s.p =  \dfrac{66 }{100} × 513

∴  s.p = \frac{66\times 513}{100}

i.e s.p = $338.58

So, The wholesale price = s.p = $338.58

Hence, The whole price at electronics store is $338.58  Answer

A presidential candidate plans to begin her campaign by visiting the capitals in 4 of 42 states. What is the probability that sh
marissa [1.9K]

Answer:

P (She selects the route of four specific capitals) = \frac{1}{2686320}=(3.7226)10^{-7}

D. No,it is not practical to list all of the different possible routes because the number of possible permutations is very large.

Step-by-step explanation:

Let's start assuming that each route is equally likely to be chosen.

Assuming this, we can calculate P(A) where the event A is ''She selects the route of four specific capitals'' doing the following :

P(A) = Favourable cases in which the route of four specific capitals is selected / Total number of ways in 4 of 42 states

The favourable cases in which the route of four specific capitals is selected is equal to 1 .

For the denominator we need the permutation number of 4 in 42.

The permutation number is defined as :

nPr=\frac{n!}{(n-r)!}

42P4=\frac{42!}{(42-4)!}=\frac{42!}{38!}=2686320

The probability of event A is : \frac{1}{2686320}=(3.7226)10^{-7}

Finally for the other question : The option D is the correct because the number of possible permutations is 2686320 and is very large to be listed.

When a is divided by 7, the remainder is 5; and when b is divided by 7, the remainder is 4. What is the remainder when a + b is
Makovka662 [10]

Answer:

9

Step-by-step explanation:

35(a) / 7 = 5

28(b) / 7 = 4

a + b = 35 + 28

35 + 28 = 63

63 / 7

= 9

Hope that helps! :)

kap26 [50]
You can set up proportions to find the width of the stream.

6/7.5=x/28

Cross multiply and solve for x.

168=7.5x

Divide by 7.5

x=22.4 ft

The stream is 22.4 ft wide
