Answer: 4/7
Find the greatest common factor between 8 and 14, which is 2. Then divide both numbers by 2 and u get 4 and 7. Thus 8/14=4/7
Answer:
diameter = 28 cm
Step-by-step explanation:
circumference = 2πr
88 cm = 2 * 3.14.*r. ( π = 3.14 )
r = ( 88)/(3.14*2)
r = 14 cm
diameter = 2 * radius
diameter = 2 * 14 cm
diameter = 28 cm
The answer is 28 for the volume
Z- score is a statistical tool that is used to determine the probability of finding a number or a value under a normal distribution plot. A normal distribution assumes that the mean is equal to zero and that the standard deviation is equal to 1. The expression to find the z score is z = (x -∪)/∅ where ∪ is the mean and ∅ is the standard deviation.
a. p= (98/116)* 0.90 = 0.76
b. x > 98 then we use z-score, wbut find first standard dev, ∅
∅ = 116 * 0.90 *(1-0.90) = 10.44
z = (98- 116*0.90)/10.44 = -0.613
p = 0.73
c. x<100
z = (100- 116*0.90)/10.44 = -0.42
p=0.66
d. p = 0.73-0.66 =0.07
Answer: B.) 1 and 111 only
Real, rational
Step-by-step explanation: Real is an encompassing terms when defining numbers as it includes all integers, whole, rational and irrational numbers. Therefore 75% belondmgs to a category of real numbers.
75% which is equivalent to 75/100 is a rational number as it can be written in the form p/q . where both p and q are integers and q is not 0. This also means 75% is not an irrational number.
75% = 0.75 is neither a whole number nor an integer as it contains decimal.
75% is not a natural number as natural numbers are counting numbers starting from 1.
