Answer:
5/16
Step-by-step explanation:
P(tails) = 1/2
P(>3) = 5/8
P(tails AND >3) = 1/2 × 5/8 = 5/16
Answer:
<em>f(g(2))=7</em>
Step-by-step explanation:
<u>The Composite Function</u>
Given f(x) and g(x) as real functions, the composite function
is defined as:
![(f\circ g)(x)=f(g(x))](https://tex.z-dn.net/?f=%28f%5Ccirc%20g%29%28x%29%3Df%28g%28x%29%29)
It can be found by substituting g into f.
The given functions are:
![f(x)=4x+3](https://tex.z-dn.net/?f=f%28x%29%3D4x%2B3)
![g(x)=x^2-3](https://tex.z-dn.net/?f=g%28x%29%3Dx%5E2-3)
It's required to find f( g( 2 ) )
Find g(2):
![g(2)=2^2-3](https://tex.z-dn.net/?f=g%282%29%3D2%5E2-3)
Operating:
![g(2)=4-3 =1](https://tex.z-dn.net/?f=g%282%29%3D4-3%20%3D1)
g(2)=1
Now find f(1):
![f(1)=4(1)+3](https://tex.z-dn.net/?f=f%281%29%3D4%281%29%2B3)
![f(1)=4+3 =7](https://tex.z-dn.net/?f=f%281%29%3D4%2B3%20%3D7)
Thus:
f( g( 2 ) )=7
Answer:
462 ways
Step-by-step explanation:
The formula to use in solving this problem is given as the Combination formula
The Combination formula is given as
C(n , r) = nCr = n!/r! (n - r)!
We are told that a food bakery has 12 pies unsold at the end of the day which they intend to share to 6 food banks
n = 12, r = 6
In order to ensure that at least 1 food bank gets 1 pie, we have:
n - 1 = 12 - 1 = 11
r - 1 = 6 - 1 = 5
Hence,
C(11, 5) = 11C5
= 11!/ 5! ×(11 - 5)!
= 11!/5! × 6!
= (11 × 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1)/ (5 × 4 × 3 × 2 × 1) ×( 6 × 5 × 4 × 3 × 2 × 1)
= 462 ways
Answer:
slope = 0
Step-by-step explanation:
The line with equation x = - 3 is a vertical line parallel to the y- axis
A perpendicular line is therefore a horizontal line parallel to the x- axis
The slope of the x- axis is zero, hence the slope of the horizontal line is
slope = 0
Answer:
48 cm²
Step-by-step explanation:
The copper part is two equal triangles, find a triangle's area by counting squares and multiply by two.
Total copper=(Triangle area)(2)
=b(h)(½)(2)
=b(h)
=(6)(8)
=48 cm²
