Which r–Value Represents the Strongest Negative Correlation?
A. –0.7 B. –0.22 C. 0.38 D. 0.9 Correct Answer: A. -0.7 Explanation: –0.7 is the r-value that indicates the strongest negative connection. The correlation coefficient, or r-value, is a number between –1 and 1. Strong negative correlations are indicated by values closer to –1, strong ...
ViewWhich is the Graph of f(x) = 100(0.7)x?
Correct Answer: B. As the Function f(x) = 100(0.7)^x , it can also be written as y = 100(0.7)^x because we know that y=f(x): So put the value of x =0 in the given function we get y = 100(0.7)^x y = 100(0.7)^0 y = 100(1) y = 100 So (x=0,y=100) is one coordinate on the graph Same ...
ViewWhich Pair of Triangles can be Proven Congruent by SAS?
Correct Answer: B. If any two of a triangle's sides and the angle that separates them are the same as the matching pair of sides and the angle that separates them from the second triangle, then these triangles are said to be congruent by the SAS rule. So, consider ∆ADC & ∆ADB in which ...
ViewTempestt Graphs a Function that has a Maximum Located at (–4, 2). Which could be her graph?
Function: f(x) = a(x-h)^2 + k Correct Answer: The function has a maximum and a downward-opening parabola, so the parabola opens downward, with a maximum on the vertex located at (-4, 2) that goes through (-6,-2) and (-2,-2). Related Question: Which Set of Angles can Form A Triangle. ...
ViewWhich R-value Represents the Weakest Correlation?
A. –0.75 B. –0.27 C. 0.11 D. 0.54 Correct Answer: C. 0.11 The r-value with the weakest correlation is determined by its absolute value, meaning how far it is from zero without considering whether it's positive or negative. Therefore, among the options provided, the r-value of 0.11 has the ...
ViewWhat is True About the Sum of the Two Polynomials? 6s2t – 2st2 4s2t – 3st2
A. The sum is a trinomial with a degree of 3. B. The sum is a binomial with a degree of 2. C. The sum is a trinomial with a degree of 2. D. The sum is a binomial with a degree of 3. Correct Answer: D. The sum is a binomial with a degree of 3. Since the expression is a binomial having two ...
