Answer:
0.024h
Step-by-step explanation:
We have the equation:
t 10 + t 15 = 0.6
<=> 25t = 0.6
<=> t = 0.024
It means that, it takes 0.024h for two people to complete 60% of the task
I hope it will find you well.

Answer:
Expected revenue from the single trip is $ 13.14
Step-by-step explanation:
y
p(x,y) 0 1 2 g(x)
x 0 0.025 0.015 0.010 0.05
1 0.050 0.030 0.020 0.1
2 0.115 0.075 0.050 0.24
3 0.150 0.090 0.060 0.3
<u>4 0.100 0.060 0.040 0.2 </u>
h(y) 0.325 0.27 0.18
E (x+Y) = E(X) +E(Y)
E(X)= ∑ xi g(x)i
= ( 0*0.05) + (1*0.1) + (2* 0.24) + (3*0.3) + (4*0.2)
= 0 + 0.1+ 0.48 + 0.9+0.8
=2.28
E(Y)= ∑yi h(y)
= (0* 0.325) + (1*0.27) + (2*0.18)
= 0 +0.27+ 0.36
= 0.63
E (x+Y) = E(X) +E(Y)
= 2.28 + 0.63
= 2.91
But the equation is 3x+ 10y
E(3x+ 10y)= 3E(x) + 10 E(y)
= 3(2.28) + 10 (0.63)
= 6.84 +6.3
= 13.14
Expected revenue from the single trip is $ 13.14
Answer:
810
Step-by-step explanation:
The original price of the car = 100%.
Price is decreased by 10%- price now equal 90% of original.
Let original price = x
.9x=729
x=810
Check:
810 - .1(810) = 729
True!
The answer to your question would be shown in steps. The decimal form is -1.2. You need to do a formula called "Keep, Change, Switch," which -3/4 is kept, division is turned into multiplication, and 5/8 is switched to make 8/5. Now we do the math, so we multiply -3 by 8 and 4 by 5, giving us from a fraction, -24/20, but you can simplify that, giving us the fraction, -1' 1/5 (I put ' as in that any number to the left of ' is a whole number, not a fraction for a numerator or denominator.
Hope this helped!
