Answer:
b=2 or b=-2.5
Step-by-step explanation:
We solve absolute value equations the same as any other equation using inverse operations. However, the inverse operation for absolute value requires one special condition. Since absolute values change a number to a positive regardless if it has a negative sign, we have two possible answers. When we have the absolute value operation isolated, we will set it equal to both the negative and positive option.
We now have the absolute value isolated. We will set it equal to both 9 and -9.

Volume of cylinders = pi x r^2 x height Simplifying the ratio: 1.6/3 = 16 / 30 (multiply and divide by 10 to remove the decimal) Volume Ratio = 512:27
Answer:
D) (-6, 3)
Step-by-step explanation:
In rectangle, the opposite sides are equal and each angle measures 90 degrees.
Therefore, draw the parallel sides and find the vertex of the fourth coordinate.
Here the vertex, H = (-6, 3)
Thank you.
Answer:
Median = 5
Lower Quartile = 2.5
Upper Quartile = 8.5
Step-by-step explanation:
- First of all, you need to order the numbers from lowest to greatest: 2 2 3 4 4 6 6 8 9 9
- Then, you will find at the number that sits exactly at the middle of this set of numbers. Because this is a set of numbers that has 10 numbers, you will have to look at the two middle points (4 and 6) and divide them by 2 (essentialy finding the average).
4+6=10, 10/2 = 5 = Mean
- To find the upper and lower quartiles, you basically have to find the medians of the set of numbers that are below and above the central median
- So, for the lower quartile, the set of numebrs is: 2 2 3 4. The median sits between 2 and 3, so we have to find the average of those: 2+3=5, 5/2=2.5
- For the upper quartile, the set of numbers is 6 8 9 9. The median is the average of 8+9. So 8+9=17, 17/2 = 8.5
0.007 < 0.07 < 0.69 < 0.7 < 0.701 < 0.71
