Please help!
AfilCa [17]

Answer:

a.) P(HH|C)=2/5

Explanation:

Given following:

  • P(HH) = 7
  • P(C) = 10
  • P(HH ∩ C) = 4
  • P(HH ∪ C) = 13

Solving steps:

\sf P(HH|C) = \dfrac{P(HH \cap C) }{P(C)}

\sf P(HH|C) = \dfrac{4 }{10}

\sf P(HH|C) = \dfrac{2 }{5}

for y: 10/1.25=8
for x: 30/1.25=16
4) 8/6.4=1.25 (Scale factor)
for y: 14/1.25=11.2
for x: 15/1.25= 12
5) 22.5/9= 2.5 (scale factor)
for x: 12x2.5=30
for y: 35/2.5= 14

yaroslaw [1]

Answer:

Step-by-step explanation:

  • Well I hate to break the news but 243 is not a perfect square. I'll work you through it, 243 is not a perfect square because it is not an even number. an even number must end in (0,2,4,6,8)
  • Step one. Find the square root. the square root of 243 is <em>15.588. </em>
  • Step two Is it a perfect square. No 243 just cant be a perfect square.
  • Hope this helped :)
