M < 2 = 1/2 * 120 = 60
m < 3 = 90 - 60 = 30 degrees
The answer is : Both plane A and B.
Answer:
P(prime,prime) = 4/10 x 4/10 or 2/5 x 2/5 = 4/25
Step-by-step explanation:
2,3,5,7 are primes from 1 through 10
probability of drawing a prime card is 4/10
Answer:
x=10
Step-by-step explanation:
Using Pythagorean theorem,
(√13^2-12^2)×2
(√169-144)×2
(√25)×2
5×2=10
Answer:
0.8914
Step-by-step explanation:
You want to find the z-values associated with the x-values:
z = (x -μ)/σ
z1 = (57 -90)/12 = -2.75
z2 = (105 -90)/12 = 1.25
Look up these values in a probability table and find the difference of the table values.
p(z < z1) ≈ 0.00298 . . . . from a table or calculator
p(z < z2) ≈ 0.89435 . . . . from a table or calculator
p(57 < x < 105) ≈ 0.89435 -0.00298 = 0.89137 ≈ 0.8914
