Answer:
The best predicted IQ score is 103.
Step-by-step explanation:
We are given the following regression equation:
where y is the predicted IQ score and x is the brain volume.
y is the dependent variable and x is the independent variable.
Significance level = 0.05
We have to find the best predicted IQ score with a brain volume of 998 cubic cm.
We put x = 998 in the equation.
Thus, the best predicted IQ score is 103.
Answer:
x = 4.
Step-by-step explanation:
2x + 4 = 5x – 8
Subtract 2x from both sides:
4 = 5x - 2x - 8
Add 8 to both sides:
4 + 8 = 3x
3x = 12
x = 4.
Answer:
Robin earns 635 + 0.02*(12350-6500) dollars.
Step-by-step explanation:
Just know please mark branliest
y = x² + 6x + 5
Use the formula: -b/2a
a = 1
b = 6
- 6 / 2
= -3
The x-coordinate of the vertex is -3
Plug the x value back into the original equation to find the y-coordinate of the vertex
y = (-3)² + 6(-3) + 5
y = -4
<h3>Answer: (-3,-4)</h3>
So, the size of the smaller squares will be 6 by 6. So the radius should be 3.
