Multiplying both sides by 14
2*3=h-(2*2)
6=h-4
h=6+4
h=10
Answer: D and F
Step-by-step explanation:
The range rule of thumb is that the range is four times the standard deviation. The range in this case is 922 cubic cm to 1496 cubic cm, i.e., 574 cubic cm.
Therefore, according to the rule, the standard deviation is 574 cubic cm/4 =
143.5 cubic cm. The actual standard deviation is 161.7 cubic cm. The difference is 161.7 - 143.5 = 18.2. Since this is greater than 15 cubic cm, the rule in this case is not accurate.
Answer and Explanation:
<em>Solving 3x + 2y = 9 for y gives y = -(3/2)x + (9/2).

Answer:
option B) Bar 2
Step-by-step explanation:
The histogram represent the number of gallons of gasoline on x axis.
The number of drivers purchase weekly on y axis.
In this histogram 5 Bars are shown.
First bar represents = 5 drivers
Second bar represents = 6 drivers
Third bar represents = 1 driver
Fourth bar represents = 3 drivers
Fifth bar represents = = 4 drivers
So the second bar represents the the number of gallons most drivers purchased during the week.
Therefore, option B) Bar 2 is the correct answer.
