Answer:
About $4.46
because you can't pay 4.466666667
Step-by-step explanation:
6 people
4 tacos------$5.00
2 burgers--$5.30
4 fries-------$9.00
6 juices-----$7.50
_______________
food ---------$26.80
divide $26.80 by the number of people so 6 then you get 4.466666667 and have to round up
Answer:
$19,100
Step-by-step explanation:
The expected profit would be the probability of profit multiplied by the profit and the sum of probability of loss multiiplied by the loss.
So, we can say:
E(p) = P(p)*P + P(L)*L
Where
E(p) is expected profit
P(p) is probabilty of profit (0.7)
P is the profit (35,000)
P(L) is probability of loss (0.3)
L is the loss (-18,000)
Substituting these values, we get:
E(p) = P(p)*P + P(L)*L
E(p) = (0.7)(35,000) + (0.3)(-18,000)
E(p) = 19,100
The expected profit is $19,100

Answer:
<em>cos a = -1.28 and 0.78</em>
Step-by-step explanation:
The question is not properly written. This is the correct question:
If sina×tan(a) = 1/2, find cosa
According to trigonometry identity;
tan a = sina/cosa
sina×tan(a) = sin a * sina/cosa
sin²a/cos a = 1/2
(1-cos²a)/cosa = 1/2
Cross multiply
2(1-cos²a) = cos a
2 - 2 cos²a = cos a
2cos²a + cos a - 2 = 0
Let P = cos a
2P² + P -2 = 0
P = -1 ±√1-4(2(2)/2(2)
P = -1 ±√1+16/4
P = -1 ±√17/4
P = -1±4.12/4
P = -1-4.12/4 and -1+4.12/4
P = -5.12/4 and 3.12/4
P = -1.28 and 0.78
Since P = cos a
<em>Hence cos a = -1.28 and 0.78</em>
9y(8y² - 2y + 4)
9y(8y²) - 9y(2y) + 9y(4)
72y³ - 18y² + 36y
