I hope this helps :))
Answer:
Option I
Step-by-step explanation:
Given that for families who live in apartments the scatterplot of the family’s income and the amount of rent they pay is approximately linear with a correlation of r = 0.60.
This implies that there is a positive association between income and rent paid.
Also since r is greater than 0.5, we can say that there is a moderately strong correlation.
All these can be interpreted as if income goes high, rent also would be higher.
The rise in rent due to income would be 0.6^2 =36% only
The regression line need not pass through 60% of income rent data points but it passes through average of the data points.
Hence only option I is right.
5^2(2-sqrt3) is the answer here is the link to how to do it https://socratic.org/questions/suppose-an-isosceles-triangle-abc-has-a-30-and-b-c-5-what-is-the-leng...
Hey there! :)
<em>First, find the area of the rectangle</em>
Formula = l · w
l = 16
w = 8
16 × 8 = 128
<em>Now, find the area of the triangle</em>
Formula = (b · h) ÷ 2
b = 4
h = 6
(6 · 4) ÷ 2
↓
24 ÷ 2 = 12
<em>Add both areas</em>
128 + 12 = 140
The area is 140 sq. ft
Hope this helps :)
2x² +8y = 121.5
<span>8y = 121.5 - 2x</span>²
and,
<span>x</span>²<span>-8y = 121.5 </span>
<span>-8y = 121.5 -x</span>²
<span>8y = x</span>²<span>-121.5 </span>
<span>Now, equate the two 8y's </span>
<span>121.5-2x</span>²<span> = x</span>²<span> -121.5 </span>
<span>-3x</span>²<span> = -121.5-121.5 </span>
<span>-3x</span>²<span> = -243 </span>
<span>3x</span>²<span> = 243 </span>
<span>x</span>²<span> = 81 </span>
<span>x = ±9</span>
