the manager of a grocery store has taken a random sample of 100 customers. the average length it took these 100 customers to check out was 3.0 minutes. It is known that the sd of the check out time for all customers who shop at this grocery store is one minute. The standard error of the sample mean equals

we need to divide the number of toy dinosaurs, 156, by the number of brothers, 4:

in order to estimate, we can use compatible numbers:

156 ÷ 4

  ↓

160   ÷ 4 = 40        

the correct answer is a).

its four gallons, i took the test and this was right.

step-by-step explanation:

on the dot where it starts for four gallons, that's when it doesn't move up any more.

the transitive property of equality.

step-by-step explanation:

the correct answer is:

the transitive property of equality.

explanation:

we know that  ∠bcd is congruent to  ∠pbc. we also know that  ∠pbc is congruent to  ∠bad.

we can substitute  ∠bad for  ∠pbc in the first angle congruence statement to give us:

∠bcd is congruent to  ∠bad.

algebraically, the transitive property states if a=b and b=c, then a=c. it basically allows us to substitute equal values. since that is what we did, this is the transitive property.
