Answer:
Answer is 4.1 shirts.
Step-by-step explanation:
The number of T-shirts sold by each students are :
3, 4, 8, 5, 2, 5, 0, 5, 3, 4, 3, 7
To find out mean of the data we apply formula of mean :
Sum of the values / total number of the value
Mean = (3+4+8+5+2+5+0+5+3+4+3+7) / 12
= 49 / 12 = 4.08
When rounded to the nearest tenth we get 4.1 shirts.
The mean of the data set rounded to the nearest tenth is 4.1 .
Answer: –145 is the 25th term in this series where each term is 7 less than the preceding term.
Step-by-step explanation: Find the difference between the numbers given.
They are decreasing by 7.
The requested term is 25. Subtract -1 . = 24 (n-1)
Multiply 24 × -7 = -168
Add that to to first term
23 + (-168) = the 25th term
–145 is the 25th term in this series where each term is 7 less than the preceding term.
Answer:
Your answer is going to be D
Step-by-step explanation:
Add 100° with 30° and subtract that sum from 180°.
1 cubic foot = 7.48 gallons
1 gallon = 8.33 lbs
1 cubic foot (in lbs weight) = 7.48 gallons * 8.33 lbs = 62.3084 lbs = 62.3 lbs
1 lb = 16 oz
1 cubic foot water = 62.3084 lbs * 16 oz = 996.9344 is = 996.9 oz = 997 oz

Answer:
(x, y, z) = (1/3, 2/3, 1)
Step-by-step explanation:
We can use the first equation to write an expression for x that can be substituted into the other equations.
x = 1 -y
2(1 -y) -y +z = 1 ⇒ -3y +z = -1
(1 -y) +2y +z = 8/3 ⇒ y +z = 5/3
Subtracting the first of these equations from the second gives ...
(y +z) -(-3y +z) = (5/3) -(-1)
4y = 8/3
y = 2/3
z = 5/3 -y = 1
x = 1 -y = 1/3
The solution is (x, y, z) = (1/3, 2/3, 1).
