Answer:
A x < 3
Step-by-step explanation:



5(9-x) < 10*3
5(9-x) < 30
9-x < 30/5
9-x < 6
-x < 6 - 9
-x < -3
x < 3
Distance from start to look out point is calculated below
d1 = 8 3/4 miles - 0 miles = 8 3/4
Distance from look out point to giant boulder is,
d2 = 8 3/4 miles - 4 1/4 miles = 9/2 miles = 4.5 miles
Thus, the answer is equal to 4 1/2 miles. The answer is letter C.
Answer:
the probability that Jack draws the blue ball is 0.38539
Step-by-step explanation:
Given the data in the question;
box contains
blue balls = 5
red balls = 8
Jim and Jack start drawing balls from the box, respectively, one at a time, at random, and without replacement
Now,
on the first attempted;
⇒ ( 8/13) × ( 5/12) = 10/39
on the second attempt;
⇒ ( 8/13 ) ( 7/12) ( 6/11 ) ( 5/10 ) = 14/143
on the third attempt;
⇒ ( 8/13 ) ( 7/12) ( 6/11 ) ( 5/10 ) ( 4/9 ) ( 5/8 ) = 35/1287
on the fourth attempt;
⇒ ( 8/13 ) ( 7/12) ( 6/11 ) ( 5/10 ) ( 4/9 ) ( 3/8 ) ( 2/7 ) ( 5/6 ) = 5/1287
so we add everything;
⇒ 10/39 + 14/143 + 35/1287 + 5/1287
= 0.38539
Therefore, the probability that Jack draws the blue ball is 0.38539
Rectangle, because it has two lines of symmetry
