Answer:
Solving 
we get 
Step-by-step explanation:
We need to find solution of
Solving the inequality:
Multiply 6 with terms inside the bracket
Subtracting 12 on both sides
Adding 4x on both sides
Divide both sides by -2 and the inequality will be reversed i.e < will be changes to >
So, after solving we get
Answer: Choice B
===================================
A more in depth look
Choice A is true because the points are going downward as you read from left to right. The points aren't all on the same line but they are close to one. We can cross choice A off the list.
Choice B is false. So this is the answer. The fact that the points are close to the same line indicates that the r value is close to -1 rather than 0. If the points were randomly scattered about, or if they fell on a curve such as a parabola, then the linear correlation coefficient r would be (closer to) zero.
Choice C is true. The explanatory variable is the independent variable x. We can cross choice C off the list.
Choice D is true. The points are fairly close to the same straight line. It's not perfect but it's good enough. We can cross choice D off the list.
Answer:
23.2586 ; IQ ; hours spent studying per week
Step-by-step explanation:
Given the regression model:
y = 6.9+0.055x1 +0.107x2 + 0.0853X3.
IQ scores = (X1)
Hours spent studying each week = (X2),
one's high school average = (x3)
The multiple standard error is 6.313 and R^2=0.826.
What is the predicted GPA for a student with a IQ of 108, 32 hours spent studying per week and a high school average of 82?
X1 = 108 ; X2 = 32 ; X3 = 82
y = 6.9 + 0.055(108) + 0.107(32) + 0.0853(82)
y = 23.2586
B.
The Independent variable with the smallest effect on GPA is the variable with the smallest Coefficient, which is IQ with a Coefficient of 0.055
C.
The Independent variable whiae unit change has the greatest effect on GPA is X2, hours spent studying per week as it has the highest Coefficient of all independent variables with a Coefficient value of 0.107.
Answer: 1/16
Step-by-step explanation: ur right:)
Answer:
No
Step-by-step explanation:
Let's test these values using the Pythagorean Theorem.
a^2+b^2=c^2
where a and b are the legs and c is the hypotenuse.
a and b are the legs, or the shorter sides. 5 and 12 are the shorter sides, so they are a and b.
c is the hypotenuse, or the longest side. 14 is the longest side, so it is c.
5^2+12^2=14^2
Evaluate all the exponents
25+144=196
Add 25 and 144
169=196
169
196
169 is not equal to 196, so 5, 12 and 14 cannot be a Pythagorean Triple
