I mean I'm not sure what the question is asking for but after 25 months he won't have any money left lol hope that helped ♡
Answer:
The graph is attached.
Step-by-step explanation:
The exercise says that Elon took 35 seconds to pull the boot up to the surface, how the constant rate is:
- Constant rate: 0.1 meters per second.
To know the meters below the surface that is the boot, we multiply the constant rate by the time Elon took to pull up it:
- Boot depth = 0.1 m/s *35 s
- Boot depth = 3.5 meters.
How the boot is pulling up through the time, the formula must subtract the time from the depth, how is below:
Where:
<em>a = depth.</em>
<em>t = time.</em>
First, we define variables:
x: small hat
y: medium hat
z: large hat
We now write the system of equations:
x + y + z = 47
5.50x + 6y + 7z = 302
-3x + y = 0
We can write the system in matrix form as:
Ax = b
Where,
A = [1 1 1; 5.50 6 7; -3 1 0]
b = [47; 302; 0]
x = [x; y ; z]
Solving the system we have:
x = 6
y = 18
z = 23
Answer:
the coach did purchase 23 large hats
d. 23
Answer:
<em>55mph
. None of the options are correct
</em>
Step-by-step explanation:
If the speed varies inversely as the time it takes to drive, then v ∝ 1/t. where;
v is the speed
t is the time taken
Hence;
v = k/t with k being the constant of proportionality.
Since it takes Kris 5 hours when driving at 55 mph, we will substitute v = 55mph and t = 5 hours. into the equation above to get the value of k as shown:
55 = k/5
Cross multiply
k = 55*5
k = 275
Hence, to calculate the speed it will Martin to drive for 5 hours, we will substitute k = 275 and t = 5 into the original equation v = k/t as shownl
v = 275/5
v = 55 mph
<em>Hence, we can conclude that Martin will also need to drive at a speed of 55mph if he wants to take 5hours.</em>
Answer:
(A)
(B)
Then the cumulative function would be
if 0<x<1
0 otherwise.
Step-by-step explanation:
(A)
We are looking for the probability that the random variable X is greater than 0.8.
(B)
For any 
you are looking for the probability 
which is
Then the cumulative function would be
if 0<x<1
0 otherwise.
