Answer:
2.2
Step-by-step explanation:
41/9 is 2.15789473684
since you need it to the nearest tenth, just get rid of the other numbers past the five, you will then have 2.15
since you are looking for the nearest tenth, you need to look at the 2nd number after the decimal place to determine whether it rounds up or down. ( a helpful rule is 5 or above, give it a shove. 4 or below, leave it alone. because the 2nd digit is 5 you need to give the 1 a shove and turn it into a 2. Since you gave the 5 a shove, you need to get rid of that 2nd digit in your answer.
FINAL ANSWER: 2.2
Answer: A. 0.4899 B. 14
Step-by-step explanation:
If X = random variable
then, the standard deviation of the sampling distribution of X = 
A.
GIven: 
The standard deviation of the sampling distribution of X = 
B. Let n be the sample size,

Hence, the required sample size = 14
Answer:
I use equal signs throughout but they are meant to be less than or equal to signs.
s=sandwiches
4.5s+6 less than or equal to 50
The answer is s is less than or equal to 12
Step-by-step explanation:
Finding Inequality
1. we know everything costs 50 in total so that is on one side of the equal sign.
____=50
2. we know he already spent 6 dollars so the money he can spend is 6 dollars less.
____+6=50
3. Each sandwich costs 4.50 $ so how much money does he have left to spend? we figure that out by multiplying the price by the number of sandwiches.
4.5s+6=50
Solving
1. 4.5s-6=50
First use the addition property of equality and add 6 to both sides.
2. 4.5s=56
Then use the division property of equality and divide each side by 4.5
3. you get a decimal but since you can't buy half a sandwich the answer is
s is less than or equal to 12
Answer:
I think the answer are C, B, C, and A.
