Answer:
106
Step-by-step explanation:
Given :
Number of the set of siblings = 20
This 20 pair yields = 103.29, = 103.75, requals = 0.899, P-value = 0.000
Let x represents the IQ score of the younger child.
And y is the predicted value of Y(^).
So according to the question,
x = 105
and y = -9.5 + 1.1 x
Then,
y = -9.5 + 1.1 (105)
y = -9.5 + 115.5
y = 106
So the best predicted value of Y(^) is 106
The point of concurrency in the triangle is point T; an orthocenter
From the given triangle, we have the following highlights
- Three rays from the midsegments of the three sides of the triangle meet at point T
- Point T is the orthocenter of the triangle
Hence, the point of concurrency in the triangle is point T; an orthocenter

Answer:
x = 50
Step-by-step explanation:
Given
(x + 10) + (2x + 20) = 180 ( remove the parenthesis )
x + 10 + 2x + 20 = 180, that is
3x + 30 = 180 ( subtract 30 from both sides )
3x = 150 ( divide both sides by 3 )
x = 50
Answer:
Option D. -0.901
Step-by-step explanation:
we know that
<u>The correlation coefficient</u> r measures the strength and direction of a linear relationship between two variables. The value of r is always between +1 and –1
Using a Excel tool (Correl function)
The value of coefficient r is -0.9006876
Round to three decimal places
r=-0.901
