Answer:
He traveled 165Miles.
Step-by-step explanation:
Simple math, if it took 3hrs and he was doing 55 miles per HOUR then multiply 55 by 3.
Answer:
165 miles
Step-by-step explanation:
The equation is d = rt.
The r, or rate is 55, and the t, time is 3. Multiply 55 by 3 to get 165.
Solve the differential equation [tex]\frac{1}{6x} * \frac{dy}{dx} = y\sqrt{3x^{2} - 1 }[/tex]
A. [tex]e^{2/3} \sqrt{(3x^{2} -1)^{3}}[/tex]
B. [tex]C*e^{2/3} \sqrt{(3x^{2} -1)^{3}}[/tex]
C. None of these
This ODE is separable as
1/(6x) dy/dx = y √(3x ² - 1)
→ dy / y = 6x √(3x ² - 1) dx
Integrate both sides:
∫ dy / y = ∫ 6x √(3x ² - 1) dx
The left side is trivial. For the right side, substitute u = 3x ² - 1 and du = 6x dx :
∫ dy / y = ∫ √u du
ln|y | = u ³′² + C
(that is, u is raised to the 3/2 power)
ln|y | = (3x ² - 1)³′² + C
Solve for y by taking the exponential of both sides:
exp(ln|y |) = exp((3x ² - 1)³′² + C )
y = exp((3x ² - 1)³′²) × exp(C )
y = C exp((3x ² - 1)³′²)
which can be written as
y = C exp(√((3x ² - 1)³))
which makes the answer none of these; this solution can't be expressed as either option given in A or B.

The car they will be using uses 6.3 litre/100km and runs on 50 ppm
diesel which will cost them R17.82/litre. Determine their fuel cost in
cents per kilometre.
(5)
Answer:
[tex]Cost = 112.266[/tex] cent/km
Step-by-step explanation:
Given
[tex]Unit\ cost = R17.82/litre[/tex]
[tex]Rate = 6.3litre/100km[/tex]
Required
The fuel cost in [tex]cent\ per\ km[/tex]
This is calculated using:
[tex]Cost = Unit\ cost * Rate[/tex]
[tex]Cost = R17.82/litre * 6.3litre/100km[/tex]
[tex]Cost = R17.82 * 6.3/100km[/tex]
[tex]Cost = R1.12266/km[/tex]
Multiply by [tex]100[/tex] to get the cost in cents
[tex]Cost = 1.12266 * 100[/tex] cent/km
[tex]Cost = 112.266[/tex] cent/km

Step-by-step explanation:
The sample space of a random experiment is {a, b, c, d, e, f}, and each outcome is equally likely. A random variable is defined as follows:
Outcome a b c d e f
X 0 0 1.4 1.4 2 3
Determine the probability mass function of X. Use the probability mass function to determine the following probabilities.
A) P(X = 1.6).B) P(0.5 < X < 2.7).C) P(X > 3).D) P(0 ≤ X < 2).E) P(X = 0 or X = 2).
Answer:
X ____ : 0 ______ 1.4 _____ 2 _____ 3
P(X) ___ 1/3 _____ 1/3 _____ 1/6 ____ 1/6 ;
0 ;
1/2 ;
0 ;
2/3 ;
1/2
Step-by-step explanation:
Each has the same probability ;
X ___ : 0 ___ 0 ___ 1.4 ____1.4 ___ 2 ___ 3
P(x) __ 1/6 __1/6 ___ 1/6 ___ 1/6 ___1/6 __ 1/6
Probability : required outcome / Total possible outcomes
X = 0
P(x = 0) = 1/6 + 1/6 = 2/6 = 1/3
X = 1.4
P(x = 1.4) = 1/6 + 1/6 = 2/6 = 1/3
X = 2
P(X) = 1/6
X = 3
P(x) = 1/6
Hence ;
X ____ : 0 ______ 1.4 _____ 2 _____ 3
P(X) ___ 1/3 _____ 1/3 _____ 1/6 ____ 1/6
A) P(X = 1.6).B) P(0.5 < X < 2.7).C) P(X > 3).D) P(0 ≤ X < 2).E) P(X = 0 or X = 2).
A.)
P(X = 1.6) = 0
B.)
P(0.5 < X < 2.7) = p(x = 1.4) + p(x = 2)
P(0.5 < X < 2.7) = 1/3 + 1/6 = (2 + 1) / 6 = 3/6 = 1/2
C.)
P(X > 3) = 0
D.)
P(0 ≤ X < 2) = P(0) + P(1.4)
P(0) + P(1.4) = 1/3 + 1/3 = 2/3
E.)
P(X = 0 or X = 2) = 1/3 + 1/6 = (2 + 1)/6 = 3/6 = 1/2

what is the answer to 4t−t+2
Answer:
3t+2
Step-by-step explanation:
First, we focus on the part with the "t" variable. Then we subtract the values with variables which gets us 3t. Finally, we can't do anything with the +2, so our solution is 3t+2.
the length of the Boston Marathon is about 26 miles. A mile is equal to 1.609 kilometers. How many kilometers does a runner cover if he or she completes in the race
Answer:
41.834
Step-by-step explanation:
The complete length of the boston marathon is 26 miles
A mile is 1.609 kilometers
Therefore the number of kilometers a runner needs to run to complete the race can be calculated as follows
= 26 × 1.609
= 41.834
Hence the runner needs to run 41.834 kilometers

This table models function m.
Answer:
A: The y-intercept of function m is less than that of function n.
Step-by-step explanation:
From the table, we see that when x = 0, m(x) = -6.
This means that the y-intercept of function m is -6.
For the function "n", we are told it passes through (-1, 0) and (0, 2)
We see that at the second coordinate, at x = 0, y = 2.
This means that the y-intercept of the n function is at 2.
Therefore,we conclude that the y-intercept of function m is less than that of function n.
Which equation shows a correct relation for triangle RSQ?
Answer:
sinQ=cosR
Step-by-step explanation:
First we need to find out the measure of ∠R.
The sum of all the angles in a triangle add up to 180. Therefore:
∠Q+∠R+∠S=180
66+∠R+90=180
∠R=180-156
∠R=24°
Since ∠Q≠∠R, sinQ≠sinR. So the first option is incorrect - let's try the second one.
sinQ=cosR
sin66=cos24
0.9135454576=0.9135454576
So the second equation is the correct relation.

g Use the information below for questions 1 through 5. A San Francisco-based tech firm is able to keep 80% of its new employees after one year. Assume that the retention probability of each new employee is independent of other employees. Q1. What is the chance that two randomly sampled new employees will both be able to survive their first year
Answer:
0.64 = 64% probability that two randomly sampled new employees will both be able to survive their first year
Step-by-step explanation:
For each employee, there are only two possible outcomes. Either they survive the first year, or they do not. The probability of an employee surviving the first year is independent of other employees. This means that we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
A San Francisco-based tech firm is able to keep 80% of its new employees after one year.
This means that [tex]p = 0.8[/tex]
Q1. What is the chance that two randomly sampled new employees will both be able to survive their first year
This is P(X = 2) when n = 2. So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 2) = C_{2,2}.(0.8)^{2}.(0.2)^{0} = 0.64[/tex]
0.64 = 64% probability that two randomly sampled new employees will both be able to survive their first year
