Hello!
--------------------------------------------------------
Solution:
The ratio is expressed as 4 to 1.
Add these parts together.
4 + 1 equals 5.
Now divide.
150 divided by 5 results in 30.
Next, multiply to find Ivan's share.
30 multiplied by 4 gives us 120.
30 multiplied by 1 equals 30 for Tanya.
Verify.
120 plus 30 totals 150.
Then subtract.
120 minus 30 equals 90.
--------------------------------------------------------
Answer:
Ivan possesses £90 more than Tanya!

I hope this has been helpful! Best of luck!
you can set this up with the equation;
x + (x + 42) = 138
start by combining like terms;
2x = 138 - 42
2x = 96
x = 96/2
x = 48
we've found x now plug it back into the original equation.
48 + (48 + 42) = 138
48 + 90 = 138
hope it helped...if you have any concerns just let me know:)
The formula for distance in this scenario is:
d ^ 2 = (12 * 1.5) ^ 2 + (8 * 1.5) ^ 2
Rewriting gives us:
d ^ 2 = (18) ^ 2 + (12) ^ 2
d ^ 2 = 324 + 144
d ^ 2 = 468
d = √(468)
d = 21.63 Km
Answer:
1) She failed to calculate the total distance each had covered in 1.5 hours.
2) She should have applied 12 km for Joseph's distance and 18 km for Isabelle's distance.
Answer:
0.8753
Step-by-step explanation:
Determine the likelihood that your job will complete before 10:01 am.
In this scenario, the expected value of an Exponential distribution is E(X)=12.
To find the probability for the third job, we apply the Poisson Distribution with a parameter of 1/λ.
This gives us E(Y) =1/12.
Since the third job is expected to be ready by 10:01 AM, we have E(Y)=61/12.
Hence, the probability sought is

=1- POISSON(3,5,true)
=1-0.1246
=0.8753
