Greetings!
Let's rewrite the equation:
b = 4c - s².
Plug in your values:
b = 4(25) - (9)²
Now simplify:
4 times 25 equals 100
9 squared equals 81
So, b = 100 - 81
Calculate:
100 minus 81 equals 19
b is 19.
I hope this helps!

From -∞ to -4 the blue line is situated above the X axis, indicating that it is >0
Between -4 and -3, the blue line is below zero
Thus, the correct answer is: F(x) > 0 over the interval (-∞,-4)
To understand the stacking of cups, start with the height of one cup plus its lip's height. Following that, continue to add the height of each lip until the desired total height is reached. Thus, the total number of cups needed is 19.
Answer:
(b)E(x)=1.3087
(c)Variance of x =1.7119
(d)E(y)=2.0447
Step-by-step explanation:
The random variable x refers to the average number of cups of coffee consumed daily.
The total number of respondents equals 1014
(a) Probability distribution for x.
(b) Expected value for x
E(x)=1.3087
(c) Variance for x
Variance 
(d)
E(y)=2.0447
The expected value for y surpasses that of x.
The maximum number of plates Lenin can create is 4, with each plate containing 3 pieces of chicken and 4 rolls. Step-by-step explanation: Lenin is preparing dinner plates with 12 pieces of chicken and 16 rolls. To ensure all plates are identical without any leftover food, the greatest number of plates he can prepare is represented by the G.C.D.(12,16) = 4. Each plate will therefore include 3 pieces of chicken and 4 rolls.
