Answer:
2.5*10^-1
Step-by-step explanation:
Scientific notation must be a number from 1-10 (which is 2.5 in this case)
Use the base of 10 and exponent to express the number
Mean (μ) = 11.5 feet
Standard deviation (σ) = 1.7 feet
First we need to find the z-score for less than 13.5 feet.
The formula of z-score is : z = (X - μ)/σ
Here X= 13.5, so z = 
z = 
= 1.18
P(X < 13.5) = P(z< 1.18) =P(z< (1.1 + .08)) = 0.8810 (from z-score table)
P(X< 13.5) = 88.1% (for making percentage from decimal, we need to multiply by 100)
So, the probability that a randomly selected tree is less than 13.5 feet tall = 88.1%
The answer is C. 51 because we can see that all of the numbers are divisble by 5 except for 51
an easy way to tell is if the number ends in 0 or 5, it is divisible by 5
51 is the only one that doesn't end in 0 or 5 so it isn't divisible by 5 (it's divisible by 3 and 17)
the answer is C. 51
Answer:
The answer is D
Step-by-step explanation:
because if you measure and solve it you get supplementary angles. Also all the angles total equal to 360.
