Answer:
I could only find a single semi-complete question on that paper due to the quality of the picture. <u>The carbon dioxide and water escape from the tube, because as gases, they do not have a definite shape or volume, and instead expand to fit whatever container they are in.</u>
Hope it helps

(a)In this region, are the events "silver" and "black" mutually exclusive:? Choose 1 answer
(A) Yes (B) No
(b) Find the probability that a randomly selected car from this region is mainly silver OR mainly black. P (silver OR black)=
Answer:
(a)Yes
(b)0.41
Step-by-step explanation:
(a) The events silver and black are mutually exclusive. Although a car's color can consist of both silver and black, its main color can only be either silver or black. It cannot be both
(b)In probability theory, given two mutually exclusive events A and B.
P(A or B)=P(A)+(B)
Therefore:
P (silver OR black)= P(silver) + P(black)
= 0.22 + 0.19
= 0.41
Answer:
Option A: −5+i
Step-by-step explanation:
In the complex plane, the real part of the number is expressed in the horizontal axis, and the imaginary part is expressed in the vertical axis. So, to find the distance of a point to the origin, we just need to apply the distance formula with the second point being (0,0):
A. −5+i
real part: -5
imaginary part: 1
distance to origin: D = sqrt((-5)^2 + 1^2) = 5.099
B. −2+4i
real part: -2
imaginary part: 4
distance to origin: D = sqrt((-2)^2 + 4^2) = 4.4721
C. 3 + 3i
real part: 3
imaginary part: 3
distance to origin: D = sqrt(3^2 + 3^2) = 4.2426
D. 4 + 3i
real part: 4
imaginary part: 3
distance to origin: D = sqrt(4^2 + 3^2) = 5
So the farthest point from the origin is point A: −5+i

The terms in #4 are 2500, 11t, and -3w
The terms in #5 are 17 and 4d
Answer:
1. 10C4 = 210
2. 4C1 + 10C1 = 14
Step-by-step explanation:
There are total 4 types of cakes available. Chocolate, cherry, apple and plain cakes. If we select 10 cakes, the possibility that at least 1 cake is selected for every variant is 210. We use computation technique in statistics for this purpose 10C4. After calculation we get 210.
If we select 4 apple cakes and one chocolate cake then there will be 14 different ways to do this. It is assumed that the order does not matter.
