Answer:
Step-by-step explanation:
Let income=X
Given he spend 1/5of his income on food.=X/5
He spend 1/3 of his income on car=X/3
Left with=286
So
x-(X/5+X/3)=286
x-8x/15=286
7x/15=286
X=286×15/7
X=612.85
His income is 612.85.

Answer:
it should be 1.19 x 10^-7
Step-by-step explanation:
Hope its correct.
Just turn 20% into a decimal and multiply it by 65 grams, then add that number to 65 grams.
So 20%=.2, therefore 65 multiplied by .2 equals 13. Add that number (13) to 65 and you get 78!
The patient will receive 78 grams of the new dose!
Hope this helps!
Answer:
286.5 days.
Step-by-step explanation:
This is a normal distribution problem with
Mean = μ = 266 days
Standard deviation = σ = 16 days.
Let the number that corresponds to the top 10% be a.
P(x > a) = 0.1
Let the z-score of a be z'
z' = (x - μ)/σ = (a - 266)/16
Using the normal distribution table, we can obtain the z-score that corresponds to z'
P(x > a) = P(z > z') = 1 - P(z ≤ z') = 0.1
P(z ≤ z') = 1 - 0.1 = 0.9
From the tables, z' = 1.282
P(z ≤ 1.282) = 0.9
And P(z > 1.282) = 0.1
1.282 = (a - 266)/16
16 × 1.282 = a - 266
20.512 = a - 266
a = 286.512 days
