4x+3=3(x+3)
4x+3=3x+9
4x-3x=9-3
x=6
So The Father is 24 and the Son is 6

Row three: 1, 3, 3, and 1
Row four: 1, 4, 6, 4, and 1
=========================================
Explanation:
Each value can be found in Pascal's triangle. You can also use the nCr combination formula to get each value. The nCr formula is
The value of n represents the row number. The r value is the column number, so to speak, for each row.
Answer:
288
Step-by-step explanation:
Find the 18 on the x axis. Go up to the line. Then go left and you will be at 288 on the y axis.
You can also divide a known coordinate to find the rate of change, since the graph is proportional. Use (6, 96). y/x = rate of change
96/6 = 16.
Now multiply 18 and 16 to get the number of cookies.
18 x 16 = 288
Answer: 0.0497870 ; 0.87754
Step-by-step explanation:
Given that :
λ = 0.0003
Defining a continuous distribution function :
F(x) = 1 - e^-λx = 1 - e^-0.0003x ; x ≥ 0
a. What proportion of the fans will last at least 10,000 hours?
P(x ≥ 10000) = e^-0.0003(10000) = 0.0497870
b. What proportion of the fans will last at most 7000 hours?
P(x ≥ 7000) = 1 - p(x ≤ 7000) = 1 - e^-0.0003(7000)
1 - 0.12245642825 = 0.87754
Answer:
I think it's 9.
Step-by-step explanation:
50% of 18 is 9.
40% of 25 is 10 if that helps you.
I don't know if I'm correct but this might help you
