Answer:
Step-by-step explanation:
Probability of black pens = 3/14
Probability of white paper clips = 16/40
to find the probability of black pen and white paper clip we have to multiply these two probability.
3/14 x 16/40 = 48/560 = 8.6
Answer with explanation:
Coefficient of determination(r²), is defined as, how well the data values are associated with each other when Regression line is drawn. In regression analysis, the coefficient of determination measures , how well the regression predictions approximate the real data points, means it measures the closeness between two variables.The Value of r², lies between 0 to 1. If value of r²=1, it shows ,regression line that is data values are Perfectly associated with each other.
If ,r²=0, it means there is no variation between two variables.There is 0% variation between two variables.
→Coefficient of Variation=[Correlation coefficient]²
=r²
=(0.854)²
=0.854 × 0.854
=0.729316
=0.730(Approx)
The solution to the system of equation is x ≤ –4 and x > 4
<h3>Compound inequality</h3>
Given the inequality expression
2x ≤ –8 or 3x + 1 > 13
Solving individually
2x ≤ –8
Divide both sides by 2
2x/2 ≤ –8/2
x ≤ –4
For inequality 3x + 1 > 13
3x > 13 - 1
3x > 12
x > 12/3
x > 4
Hence the solution to the system of equation is x ≤ –4 and x > 4
