Answer:
-3/4, -2/5, -4/15
Step-by-step explanation:
using calculator, -3/4 = -0.75, -4/15 = -0.266666..., -2/5 = -0.40
imagine that -0.75, -0.26... and -0.40 are temperatures
the coolest temperature is -0.75, the warmest one is -0.26...
so the least number is -0.75, greater -0.40 and the greatest -0.26...
Answer:
50 times
Step-by-step explanation:
Assuming a fair coin (probability of heads = 1/2), the expected number of heads (in the sense of mathematical expectations) is 100*1/2 = 50.
Answer:
A
Step-by-step explanation:
<h3>f(x)=3x³-13x²-3x+45</h3><h3>f(x)=3x³-9x²-4x²+12x-15x+45</h3><h3>f(x)=3x²(x-3)-4x(x-3)-15(x-3)</h3><h3>f(x)=(x-3)(3x²-4x-15)</h3><h3>f(x)=(x-3)(x-3)(3x+5)</h3><h2>f(x)=(x-3)²(3x+5)</h2>
<h3><u>Roots:</u></h3><h3>x=3</h3><h3>x=-5/3</h3>
