Answer:
I don't see a graph
Step-by-step explanation:
1 1/4 * 2 + 2 1/2 * 1.5
change the fractions to decimals
1.25 * 2 + 2.5 * 1.5
2.5+3.75
6.25
The total cost is 6.25
Subtract 5 from both sides.
r+5−5>12−5
r>7
Answer : r>7
Simplify both sides of the inequality.
1/9r<10
Multiply both sides by 9.
9*(1/9r)<(9)*(10)
r<90
Answer : r < 90
Answer: The standard error of the sample mean = 0.44
Step-by-step explanation:
Standard error of the sample mean = 
<em> , where </em>
= population standard deviation , n= sample size.
Given : n= 45 , 
grams
The e standard error of the sample mean 
Hence, the standard error of the sample mean = 0.44
