Answer:
Step-by-step explanation:
Use the Pythagorean theorem a^2 + b^2 = c^2
In this case you are given a and c, so set the equation up like
2^2 + b^2 = 8^2
b^2 = 8^2 - 2^2
b =
b =
Answer:
23/60
Step-by-step explanation:
All fractions of tiles, when summed up, need to be 1
Indian red is 1/4 of the tiles
Tuscan blue is 1/6 of the tiles
Fucalyptus is 1/5 of the tiles
Sand is X of the tiles (X is the fraction we want to know)
So, we can formulate the equation:
1/4 + 1/6 + 1/5 + X = 1
applying LCM, we have:
(15 + 10 + 12 + 60X) = 60
60X = 23
X = 23/60
Answer:
0.9987
Step-by-step explanation:
Using Z score formula
z = (x-μ)/σ, where
x is the raw score = 52 inches
μ is the population mean = 94 inches
σ is the population standard deviation = 14 inches
z = 52 - 94/14
z =-3
Probability value from Z-Table:
P(x<52) = 0.0013499
P(x>52) = 1 - P(x<52)
P(x>52) = 1 - 0.0013499
= 0.99865
Therefore, the probability that, in a randomly selected year, the snowfall was greater than 52 inches is approximately 0.9987
