<span>2. There is a 20% chance that it will snow on Monday and a 40% chance on Tuesday. What is the probability that it will NOT snow on both Monday and Tuesday? </span>
<span>P( NOT snow on both Monday and Tuesday) = (1-.2)(1-.4) = 12/25 </span>
<span>c. 12/25 </span>
<span>3. The total cost of renting a sailboat is $120 plus $60 a day. How many days was a sailboat rented if the total cost was $360? Solve. </span>
<span>120 + 60d = 360 </span>
<span>60d = 360 - 120 = 240 </span>
<span>d = 4 </span>
<span>4. Two cards are chosen at random without replacement from a deck of 52 cards containing 4 kings. Which expression could be used to find the probability of choosing two kings? </span>
<span>b. 4/52 x 3/51 </span>
<span>There are 4 x 3 ways to pick 2 kings </span>
<span>There are 52 x 51 ways to pick any two cards</span>
Answer:
Step-by-step explanation:
There are a total of 7 + 9 + 2 = 18 balls in the vase, therefore, when not replacing the first ball, there would be 18 · 17 = 306 ways to pull 2 balls. There are 2 ways to choose the first black ball and then 1 way to choose the second black ball so there are 2 · 1 = 2 ways to choose 2 black balls. Therefore, the probability is 2 / 306 = .
(n+2)^4 =
(n²+4n+4)(n²+4n+4) =
n^4 + 4n³ + 4n² + 4n³ + 16n² + 16n + 4n² + 16n + 16 =
n^4 + 4n³+24n²+ 4n + 16
Hope this helps
To get this answer, you need to divide 6.5 by 5. 6.5/5=1.3 since the measure is in feet, each section is 1.3 feet long.
The two smaller angles would be 45 each and the other angle would be 90 to equal 180.
