construction = divide the figure into two parts.
now we have triangle abd and bdc.
first calculate the area of abd.
area of triangle= 1/2×base ×height
area of triangle= 1/2×18×7.5
area of triangle=67.5cm²
second calculate area of bdc
area of triangle=1/2×15.6×11.7
area of triangle=91.26cm²
area of the figure=area of abd + area of bdc
area of the figure=67.5cm²+ 91.26cm²
area of figure=158.76 cm².
Answer: Variance = 0.858
Step-by-step explanation: The variance formulae for a probability distribution is given below as
Variance = √npq
Where n = number of times experiment was performed = 9
p = probability of success = 0.09
q = probability of failure = 1 - p = 1 - 0.09 =0.91
Variance = √9×0.09×0.91
Variance = √0.7371
Variance = 0.858
undefined
so.. what value of "x" makes x+4 to 0?
the domain will be, all real numbers, except that value
about the range, "y" will take, whateve "x" can provide.. in this case... I think is all real numbers, except 0, because, if you give a few big values to "x", the fraction will simply have a bigger and bigger denominator, making the fraction smaller and smaller, ever approaching 0, but never getting there
Yes that great hope that helped :)
