Answer:
1/6
Step-by-step explanation:
Given that :
Total surveyed (u) = 120
n(Cane's chicken fingers) = 50
n(Layne's chicken fingers) = 80
n(do not like either) = 10
a)
What is the probability that someone surveyed likes both Raising Cane's and Layne's chicken fingers?
n(Cane's n Layne's) = 20
u = 120
P = required outcome / total possible outcomes
P(Layne's and Cane's chicken) = [n(Cane's n Layne's)/ u]
= 20 / 120
= 1/6
Answer:
-8b-11w+10
Step-by-step explanation:
The first term has a variable b
The second term has a variable w
The third term is a constant
They cannot be combined
Probably the question should say
, as
is negative for
.
In that case, recall that
![\cos^2x+\sin^2x=1\implies\cos x=\pm\sqrt{1-\sin^2x}](https://tex.z-dn.net/?f=%5Ccos%5E2x%2B%5Csin%5E2x%3D1%5Cimplies%5Ccos%20x%3D%5Cpm%5Csqrt%7B1-%5Csin%5E2x%7D)
Because
lies in the third quadrant, we expect
to also be negative, so we take the negative root above. Then
![\cos x=-\sqrt{1-(-0.3)^2}\approx-0.954](https://tex.z-dn.net/?f=%5Ccos%20x%3D-%5Csqrt%7B1-%28-0.3%29%5E2%7D%5Capprox-0.954)
Answer:
see below
Step-by-step explanation:
0 = x^2 + 6x – 10
Add 10 to each side
10 = x^2-6x
Take the coefficient of x
-6
Divide by 2
-6/2 =-3
Square it
(-3)^2 =9
Add 9 to each side
10+9 = x^2-6x+9
We use -3 for the square term
19 = (x-3)^2
Take the square root of each side
±sqrt(19) = x-3
Add 3 to each side
3±sqrt(19) = x
