Answer: 90 degrees.
Step-by-step explanation: since 360 degrees is a whole circle, subtract 360 from 270 to get 90 degrees.
Answer:
0.0015 or 0.15%
Step-by-step explanation:
Data
- mean age of sea turtles, μ: 80 years
- standard deviation, σ: 17.3 years
Z score is defined as:
Z = (x - μ)/σ
To find the probability of finding a sea turtle that is over the age of 131.9 years, we have to replace x = 131.9, to get:
Z = (131.9 - 80)/17.3 = 3
The 68 - 95 - 99.7 rules stands that (see figure attached):
P(Z > 3) = 0.0015
Answer:
-3, -7
Step-by-step explanation:
either x + 3 = 0 --> x = -3
or x + 7 = 0 --> x = -7
Its 3 and 7 so write the as a equation
3 is on the y axis and 7 is on the x axis
so 3y and 7x
Answer:
180*-90*=90*
Step-by-step explanation:
I think it would be 90*
