Step-by-step explanation:
Answer:
The coordinates of the fourth vertex is ( 2.1 , -3.6)
Step-by-step explanation:
Given:
The vertices are ( -2.3 and −3.6), (−2.3, and 2.2), and (2.1, and 2.2).
To Find :
The fourth coordinate = ?
Solution:
Let (a,b) be the missing coordinates
Now let us use the the mid point formula and find the missing coordinate.
Let ( -2.3 ,−3.6) be the point A
Let (−2.3,2.2) be the point B
Let (2.1, 2.2) be the point C
The mid point of AC should be BD
Step 1: Finding The mid pint of AC
The mid pint of AC
Step 2: Lets Equate the midpoints'
The mid pint of BD
=>
= (-0.1, -0.7)
a = 2.1
b = -3.6
Answer:
x=10 or x=-2
Step-by-step explanation:
add 28 to both sides
(x-4)^2=36
sqrt both sides
remember to get positive and negative roots
x-4=+/-6
add 4 to both sides
x=4+/-6
x=4+6 or x=4-6

<span>a. The number of cantaloupes sold at Central varied less than did the number sold at North.
</span>What is the MAD of the data set?
<span>{10, 9, 16, 5, 10}
</span>
mean = (10 + 9 + 16 + 5 + 10)/5 = 10
MAD = ( (10 - 10) + (10 - 9) + (16 - 10) + (10 - 5) + (10 - 10) )/5 = 12/5
The numbers of cubs in each litter were 1, 1, 2, 2, 3, 3, 3, 4, 5, and 6. The mean of these measurements is 3.
What is the mean absolute deviation?
mad = ( (3 - 1) + (3 - 1) + (3 - 2) + (3 - 2) + (4 - 3) + (5 - 3) + (6 - 3) )/10
a. 1.2
Tamar surveyed six friends, asking each how many times he or she had ridden in a helicopter. The numbers of times she recorded were 0, 0, 0, 1, 3, and 8.
What is the mean absolute deviation of the number of times? Round to the nearest tenth, if needed.
mean = (1+3+8)/6 = 2
mad = ( 2 + 2 + 2 + (2 - 1) + (3 - 2) + (8 - 2) )/6 = 14/6
c. 2.3 times
Four friends played cards. Their final scores were –6, –3, 0, and 1.
<span>What is the mean absolute deviation of their scores?
</span>
mean = (-6 - 3 - 1)/4= -10/4 = -2.5
mad = ( (6 - 2.5) + (3 - 2-5) + 2.5 + (2.5 + 1) )/2.5
mad = 4
