Phantasy [73]

Answer:

14 units

Step-by-step explanation:

Solution:-

A(5,1)B(7,1)

\sqrt{(x_{1}-x_{2} ) ^{2}(y_{2} -y_{1}x^{2}    }

AB=\sqrt{(7-5)^{2} +(1-1)^{2} }

= \sqrt{2^{2} } =2

BC=\sqrt{7-7^{2}+(6-1)^{2}  }

=\sqrt{5^{2} } =5

perimeter=2(AB)+2(BC)

= 2(2)+2(5)\\

= 4+10= 14

-----------

hope it helps...

have a great day!!

The Extreme Rock Climbing Club planned a climbing expedition. The total cost was $⁢1800, which was to be divided equally among t
CaHeK987 [17]
Let's say "p" people were going to the expedition initially, and the cost for each was "c", now, we know the total cost is 1800, so for "p",  folks that'd be  1800/p how much each one cost, namely, how many times "p" goes into 1800.

well, prior to leaving, 15 dropped out, so that leaves us with " p - 15 ", and the cost "c" bumped up to " c + 27 " for each.

\bf \begin{cases}&#10;\cfrac{1800}{p}=\boxed{c}\\\\&#10;\cfrac{1800}{p-15}=c+27\\\\&#10;----------\\&#10;\cfrac{1800}{p-15}=\boxed{\cfrac{1800}{p}}+27&#10;\end{cases}\\\\&#10;-------------------------------\\\\&#10;\cfrac{1800}{p-15}={\cfrac{1800}{p}}+27\impliedby &#10;\begin{array}{llll}&#10;\textit{let's multiply both sides by}\quad  p(p-15)\\&#10;\textit{to get rid of the denominators}&#10;\end{array}

\bf 1800p=1800(p-15)+27[p(p-15)]&#10;\\\\\\&#10;1800p=1800p-27000+27(p^2-15p)&#10;\\\\\\&#10;0=-27000+27(p^2-15p)\implies 0=-27000+27p^2-405p&#10;\\\\\\&#10;\textit{now, let's take a common factor of }27&#10;\\\\\\&#10;0=p^2-15p-1000\implies 0=(p-40)(p+25)\implies p=&#10;\begin{cases}&#10;\boxed{40}\\&#10;-25&#10;\end{cases}

well, you can't have a negative value of people... so it has to be 40.

so, 40 folks were initially going, then 15 dropped out, how many went on the expedition?  40 - 15.

c)  0.31

d) 0.00018

Step-by-step explanation:

attached below is the detailed solution

Total number of 7-poker cards are 52P7 = 133784560

A) Determine the probabilities of Seven-card straight

probability of seven-card straight = 0.00031

B) Determine the probability of four cards of one rank and three of a different rank

P( four cards of one rank and three of different rank ) = 0.0017

C) Determine probability of three cards of one rank and two cards of each two different ranks

P( three cards one rank and two cards of two different ranks ) = 0.31

D) Determine probability of two cards of each of three different ranks and a card of a fourth rank

P ( two cards of each of three different ranks and a card of fourth rank ) =  0.00018
