(8/-4) / (-3/9)=
(8/-4) * (9/3)=
72/-12=
-6
Answer:
_
66,6% = ⅔
_
33,3% = ⅓
85% = 17⁄20
80% = ⅘
75% = ¾
90% = 9⁄10
20% = ⅕
10% = ⅒
Step-by-step explanation:
To convert from a fraction to a percentage, divide both the denominator and numerator to get a decimal point, then move the decimal point twice to the right, then attach the percentage symbol:
⅒ = 0,1 = 10%
⤻⤻
⅕ = 0,2 = 20%
⤻⤻
9⁄10 = 0,9 = 90%
⤻⤻
¾ = 0,75 = 75%
⤻⤻
⅘ = 0,8 = 80%
⤻⤻
17⁄20 = 0,85 = 85%

He had been in a hospital with friends since his birth
-3 so top person is correct:)))))
Answer:
Step-by-step explanation:
Part 1
P(z < -1.45)
Using the z score table
P =
Part 2
We solve using z score formula
z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.
a) P(X >52)
x = 52
Mean = 60
Standard deviation = 8
z = 52 - 60/8
z = -1
P-value from Z-Table:
P(x<52) = 0.15866
P(x>52) = 1 - P(x<52) = 0.84134
b) P(48 < x < 64)
