Answer:
Given in the information set as
26, 34, 38, 49, 65, 76, 81
Sum = 369
No of entries = 7
Mean =52.71
When 1213 is included
New sum = 1582
No of entries =8
The new mean will be 197.75
Thus mean will be increased by 145.04
Answer:
y intercept is 10
Step-by-step explanation:
Based on the given coordinates of the quadrilateral ABCD, the slopes of the lines given at:
- Slope of AB = -7/4
- Slope of BC = 1/7
- Slope of CD = -5/3
- Slope of AD = 1/2
<h3>What are the slopes of the line?</h3>
The slope of AB is:
= (3 - (-4)) / (-4 - 0)
= -7/4
The slope of BC:
= (4 - 3) / (3 - (-4))
= 1/7
The slope of CD:
= (-1 - 4) / (6 - 3)
= -5/3
The slope of AD:
= (-1 - (-4)) / (6 - 0)
= 1/2
The rest of the question is:
The slope of AB ¯ ¯ ¯ ¯ ¯ is , the slope of BC ¯ ¯ ¯ ¯ ¯ is , the slope of CD ¯ ¯ ¯ ¯ ¯ is , and the slope of AD ¯ ¯ ¯ ¯ ¯.

Answer:
690
Step-by-step explanation:
Let
hayden have "h"
uri have "u"
and
willow have "w"
Hayden & Uri have 1250. we can write:
h + u = 1250
Hayden & Willow have 830, so we can write:
h + w = 830
Uri has 4 times than Willow, so we can write:
u = 4w
Putting 3rd equation in first, we get:
h + u = 1250
h + 4w = 1250
Now, we take 2nd and 4th equation, which are:
h + w = 830
h + 4w = 1250
Multiplying this first one with -1, gives us:
-1 * [h+w=830] = -h - w = -830
Now we add this up with 4th equation. Shown below:
- h - w = - 830
h + 4w = 1250
----------------------
4w - w = 1250 - 830
3w = 420
w = 420/3
w = 140
We know u = 4w, so u = 4 * 140 = 560
u = 560
Also, we know h + w = 830, so
h + 140 = 830
h = 830 - 140
h = 690
Thus Hayden has 690
