Multiply both sides of the equation by 20. 2z-3-5(z-6)=60. 2z-3-5z+30=60. -3z-3+30=60. -3z+27=60. -3z=60-27. -3z=33. Divide both sides by 3. Answer is: Z= -11

What is the five number summary for this data set?
MrRa [10]

Answer:

see explanation

Step-by-step explanation:

The median is the middle value of the data set in ascending order. If there is no exact middle then the median is the average of the values either side of the middle.

Given

3   8   14   19   22   29   33   37   43   49

                            ↑ middle is between 22 and 29

median = \frac{22+29}{2} = \frac{51}{2} = 25.5

The upper quartile Q_{3} is the middle value of the data to the right of the median.

29   33   37   43   49

               ↑

Q_{3} = 37

The lower quartile Q_{1} is the middle value of the data to the left of the median.

3   8   14   19   22

           ↑

Q_{1} = 14

The min is the smallest value in the data set, that is 3

The max is the largest value in the data set, that is 49

The 5 number summary is

3,  14,  25.5,  37,  49

What is the value of g(0)<br> -2<br> -1<br> 3<br> 6
Tanzania [10]

Answer:

Step-by-step explanation:

An x value of 0 can only be plugged into the equation that has a domain that includes 0. The first function's domain is between -2 and -4, so 0 is not included in that domain. In the third function, the domain is between 1 and 3, so 0 is not included in that domain, either. The middle function's domain does include 0 (0 falls between -2 and 1) so we can only evaluate this function at an x value of 0.

g(0) = -0 - 1 so

g(0) = -1
