Answer:
the answer is (x – 4)(x2 + 4x + 16).
Speed = Distance / Time
Distance = Speed*Time
For this problem, we should bear in mind that current speed has an impact on the boat speed...
for upstream, the boat goes against the current, and so its speed is
U = V - C
where V is the speed of the boat
C is the current speed
for downstream, it will be:
D = V + C
Convert the problem into mathematical equations:
4D + 3U = 116
3D + 4U = 108
4(V+C) + 3(V-C) = 116
4V + 4C + 3V -3C =116
7V + C = 116
3(V+C) + 4(V-C) = 108
3V + 3C + 4V - 4C = 108
7V - C = 108
Solving the equations:
7V + C = 116
7V - C = 108
14V = 224
V = 16km/hr —-> speed of boat
to get C:
7(16) + C = 116
C = 4km/hr
Advertising is x and revenue is y
(0,2)(2,6)
slope = (6 - 2) / (2 - 0) = 4/2 = 2
y = mx + b
slope(m) = 2
(0,2)...x = 0 and y = 2
now we sub and find b, the y int
2 = 2(0) + b
2 = b
so ur equation is : y = 2x + 2
spends 10 mill on advertising.....so x = 10
y = 2x + 2
y = 2(10) + 2
y = 20 + 2
y = 22.....so the revenue (y) of the company is 22 (million)
Answer:
Step-by-step explanation:first you multiply 0.76 by 14then multiply 0.68 by 8 then multiply 6.71 by 4. After you get your answer for each one you add them by the cost of each one
Answer:
The probability that a randomly selected woman has red/green color blindness is 0.9914
Step-by-step explanation:
Given that the proportion of women having red/green color blindness is 0.86%
Represent that with p
Convert proportion from percentage to decimal;
In probability; opposite probabilities add up to 1;
Let the probability that a woman selected have red/green color blindness be represented with q;
Subtract p from both sides
Substitute 0.0086 for p
<em>Hence, the probability that a randomly selected woman has red/green color blindness is 0.9914</em>
