C. 2+3 = 5
1/12+1/12=2/12
So C would make sense because those all add up to the answer :-)
It would be C because the 40° is acute and the last degree is obtuse
Answer:
a. 0.48
b. 0.14
c. 0.47
Step-by-step explanation:
Data provided in the question
0 - 2 0.48
3 - 5 0.26
6 - 8 0.12
9- 11 0.09
12- 14 0.05
Based on the above information
a. The probability for fewer than three phobias is
= P( x < 3)
= 0.48
b. The probability for more than eight phobias is
= P( x >8)
= 0.09 + 0.05
= 0.14
c. Probability between 3 and 11 phobias is
= P(3 < x < 11)
= 0.26 + 0.12 + 0.09
= 0.47

60/4=15
60 turtles and 15 manta rays
60+15=75
ratio= 60:75
Hope this helps!!!!
Step-by-step explanation:
So what you can do is first get ride of the parentheses around 5-m so:
Then, you can simplify the numbers inside the parentheses, so:
Then, you can get rid of the parentheses by distributing the - sign:
Next, just combine like terms:
