Answer:
(a) 21
(b)2520
Step-by-step explanation:
(a)
Using combination formula, nCr where n is the total sample and r is the limitation hence 7 combination 5.
[tex}7C5=\frac {7*6*5*4*3}{5*4*3*2*1}=\frac {2520}{120}=21[/tex]
(b)
If the scholarships are not equal
The number of ways to select the 5 students from 7 we use permutation formula hence
7P5 = 7*6*5*4*3 = 2520
y = -x + 5
5x + 2y = 14
5x + 2(-x + 5) = 14
5x + 2(-x) + 2(5) = 14
5x - 2x + 10 = 14
3x + 10 = 14
- 10 - 10
3x = 4
3 3
x = 1¹/₃
y = -x + 5
y = -1¹/₃ + 5
y = 3²/₃
(x, y) = (-1¹/₂, 3²/₃)
Answer:
expolential function
Step-by-step explanation:
In an exponential function, the independent variable, or x-value, is the exponent, while the base is a constant. For example, y = 2x would be an exponential function. Here's what that looks like. The formula for an exponential function is y = abx, where a and b are constants
The multiplicative inverse is 9/5
