Answer: 1.8x
Step-by-step explanation:
Answer:
1st Picture: m∠RPS= 15° m∠QPR=25°
2nd Picture: x= 53°
Step-by-step explanation:
1st Picture:
8x+7+9x+16=40
17x+23=40
17x=40-23
17x=17
x=1
Substitute the x values with 1 and solve.
<span>This is a matter of knowing the formulas involving the binomial distribution:
Mean = n*p = 125*0.46 = 57.5
Variance = n*p*(1-p) = 125*0.46*(1-0.46) = 125*0.46*0.54 = 31.05
Standard Deviation = sqrt(Variance) = sqrt(31.05) = 5.572252686</span>
There are not "undefined terms" but they may not have been covered in your course at this point, so what can you do ?
Parallel lines will never intersect at a point, and thus lie in the same plane perpendicular lines intersect at exactly one point and form four right angles about that point.
