Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
True mean(μ) = 77.9
True standard = 20
Sample size (n) = 50
Sample mean (m) = 82.1
Sample standard deviation (s) = 18.6
The standard error (SE) :
SE = sample standard deviation / √sample size
SE = 18.6 / √50
SE = 2.6304372
SE = 2.63
Answer:
x(2x-1)=0
3x-1x=0

x=0/2
x=0
Step-by-step explanation:
LCM
first term =3x
=3×x
second term = 4x²y
=2×2×x×x×y
third term =x(x+1)
LCM=x
Each cow makes 0.20 gallons day
5 x 0.20 = 1 gallon a day for 5 cows
3 x 0.20 = 0.6 gallons a day for 3 cows
0.6 x 5 days = 3 gallons of milk
Answer. 5 Days
If you multiply -8 and -9 it's 72 because If you multiply two negatives it turns into a positive number/answer and if you add -8 and -9 it's -17.
-8 + -9 = -17
and
-8 * -9 = 72
The unit rate would be 3 trucks per 1 hour you can find this by dividing 18 and 6 by 6
