Answer:
54
Step-by-step explanation:
4^3-4/2*5
4^3=64
64-4/2*5
-4/2=-2
64-2*5
-2*5=-10
64-10=54
Parenthesis
Exponent
Multiply or Divide (whichever comes first)
Add or Subtract (whichever comes first)

Answer:
Step-by-step explanation:
Information provided
n=100 represent the random sample taken
X=21 represent the number of bags overfilled
estimated proportion of overfilled bags
is the value that we want to test
z would represent the statistic
Hypothesis
We need to conduct a hypothesis in order to test if the true proportion of overfilled bags is higher than 0.15.:
Null hypothesis:
Alternative hypothesis:
The statistic for this case is:
(1)
And replacing the info given we got:
Answer:
46 logs on the 5th row.
Step-by-step explanation:
Number of logs on the nth row is
n = 50 - (n-1)
n = 51 - n (so on the first row we have 51 - 1 = 50 logs).
So on the 5th row we have 51 - 5 = 46 logs.
You have to figure out X by going one through 10 Once you figure it out you multiply 4 times that number and then you subtract one and you’ll get seven like 4 x 2= 8-1= 7
Answer:
Step-by-step explanation:
C11 = (1×1) + (-1×3) = 1-3 = -2
C12 = (1×2) + (-1×4) = 2-4 = -2
C21 = (2×1) + (1×3) = 2+3 = 5
C22 = (2×2) + (1×4) = 4+4 = 8
