Wanda started walking along a path 2 minutes (120 seconds) before Dave. Wanda walked at a constant rate of 5 feet per second. Da
igor_vitrenko [27]
First we write the kinematics equations:
 a
 v = a * t + vo
 r = a * (t ^ 2/2) + vo * t + ro
 For Wanda we have:
 a = 0
 v = 5
 r = 5 * t
 For Dave we have:
 v = 10
 r = 10 * (t-120)
 To solve the system of equations, we graph both functions and see where
they intersect.
 We have to intersect in the ordered pair:
 (t, r) = (240, 1200)
 answer
 If they continue walking at these rates, Dave catch up to Wanda in 240s (1200 ft)

Suzette and Bridgett are sisters. Suzette deposits $30,000 at the start of each year for 15 years into an account that earns 8.5
Nitella [24]

Answer:

Suzette makes more

Step-by-step explanation:

Suzette = 30000 x 1.085^15 = 101992.28

Bridgett = 8.5/100 = 0.85, 0.85 x 30000 = 2550, then use simple interest formula (P(1+rt) , 30000 + (15x2550) = 68250

Suzette - 101992.28 - compound interest

Bridgett - 68250 - simple interest

what are the minimum first quartile median third quartile and the maximum of the data set? 9,20,4,18,4,18,20,9
den301095 [7]
<u>Answers</u>
1. Minimum = 4
2. First quartile = 6.5
3. Median = 13.5
4. Third quartile = 19
5. Maximum = 20

<u>Explanation</u>
To calculate the measure of central tendency, you first arrange the set of the data in ascending order.  
The set of data given will be;
4, 4, 9, 9, 18, 18, 20, 20.

Part 1:
The minimum value of the data is 4.

Part 2:
The first quatile is the median of the lower half which is comprised by:
4, 4, 9, 9

1st quartile = (4+9)÷2
                  = 13÷2
                  = 6.5

Part 3:
Median of the data is;

Median = (9+18)÷2
              =27÷2
            = 13.5

Part 4:
3rd quartile is the median of the upper half which comprises of; 
18, 18, 20, 20.

3rd quartile = (18+20)÷2
                  = 48÷2
                   = 19

Part 5
The maximum of the set of data is 20.
