Answer:
Closest standard deviation of W = 4.11
Step-by-step explanation:
Randomly selected workers = n =300
Probability of workers arriving between 6:45 to 7:00 A.M = p = 6% = 0.06
According to binomial distribution:
mean = μ = n.p
= 300(0.06) = 18
variance = σ² = n.p(1-p)
= (300)(0.06)(1-0.06)
= (18)(0.94)
= 16.92
standard deviation = σ = 4.11
It 20 because it is and you multiply
The sum of the measures of all exterior angle in a polygon with n sides is always 
.
Nonagon is a polygon with 9 sides. If this nonagon is regular or equiangular, then all interior angle are congruent, and therefore all exterior angles are congruent. Then the measure of each exterior angle is 
.
Answer:
32/5
Step-by-step explanation:
K=Keep the first Fraction (You can rewrite 8 as 8/1 for when you multiply across.)
C=Change the Division Sign to a Multiplication Sign
F=Flip the Second Fraction
First, rewrite 1 1/4 as 5/4 (A mixed number can be changed to a fraction by multiplying the outside whole number by the denominator or bottom number of the fraction, then add the new rewritten whole number and the original fractional piece. In this case you would multiply the outside 1 by the bottom 4 and add it to the original 1/4. 4/4+1/4=5/4)
Second, Flip 5/4 to 4/5 and change your equation so it now reads: 8/1 x 4/5
Third, use simple fraction multiplication and multiply across to get 8/1 x 4/5=32/5
Answer:
6x + 5/6
Step-by-step explanation:
2(x + 1/4) + 2(2x + 1/3)
2x + 1/2 + 4x + 2/3
6x + 5/6
