1. $58.50
2. $72.80
3.no because 75 x .3 =22.50 and 22.50 + 75= $97.50
Answer:
Distance = 192 km
Step-by-step explanation:
To calculate the distance, the distance is given by the formula:
s = vt
where s = distance
v = average speed
t = time taken to travel
therefore, the distance is given as
s = 24miles/hour× 8 hours
= 192 miles.
The total distance is 192 miles.
To calculate the average speed on the first trip to the conference, divide the distance by the time like this:
s = vt
v = s/t
= 192 miles/ 5 hours
= 38.4 miles per hour
As you can see, the driver drove faster than she did when she was driving in bad weather.
Short Answers
P(Both) = 0.1792
Givens
The total number of roles = 100
Total number of heads = 56
Number of times rolled a four = 32 [check this for me].
Set up the probabilities.
P(H) = 56/100
P(4) = 32/100
P(H)*P(4) = P(Both)
Substitute and solve
P(Both) = 56/100 * 32/100 = 1792/10000
P(Both) = 112/625 because there are many cancellations. Or you could just express it as 0.1972
The given function is
f(x) = x⁵ ln(x)
Note that ln(x) is undefined as a real function for x ≤ 0.
Therefore the domain of the function is
0 < x <∞, or x = (0,∞).
Answer: x = (0, ∞) or 0 < x < ∞
