The probability that Tania would pick a yellow bead on the first draw, then a blue bead, and finally a yellow bead again is 1/216.
What is Probability?
The probability helps us to know the chances of an event occurring.
As it is given that the box has 6 beads of the same size, but all are different colours. therefore, the probability of any bead being selected is 1/6.
Now, we know that when Tania picks a bead she puts it back in the box, therefore, the sample size of the box will be the same and also the probability of each bead will be the same as well.
Further, the probability that Tania would pick a yellow bead on the first draw, then a blue bead, and finally a yellow bead again can be written as,
Hence, the probability that Tania would pick a yellow bead on the first draw, then a blue bead, and finally a yellow bead again is 1/216.

AABC - ADEF.
Based on the dimensions in the diagram, what is the
perimeter of AABC?
A-9 in.
B-10 in.
C-9.5 in.
D-10.5 in.
Answers
Answer:
Perimeter of ΔABC is 9.5 in.
Step-by-step explanation:
Given:
ΔABC ΔDEF
DE = 6 in.
EF = 5.25 in.
DF = 3 in.
AB = 4 in.
We need to find the Perimeter of ΔABC.
Solution:
First we will find the sides of ΔABC.
Now By Triangle similarity property which states that:
"When two triangles are similar the the ratio of their corresponding sides are equal."
From Above property we can say that;
Now we will find BC and AC
Also;
Now In ΔABC
AB = 4 in
BC = 3.5 in
AC =2 in.
Now Perimeter of ΔABC can be calculated as sum of all sides.
Perimeter of ΔABC = AB +BC +AC = 4 + 3.5 + 2 = 9.5 in
Hence Perimeter of ΔABC is 9.5 in.

Graph A
Graph B
Graph C
Graph D
Answers
Answer:
1)
Test score will decrease because the graph shows negative association.
2)
Graph A
Step-by-step explanation:
1)
Clearly from the graph we could observe from the scatter plot that:
Test score will decrease because the graph shows negative association.
( As the points or the test scores are decreasing with the increasing number of hours spent on playing games online)
2)
Positive Nonlinear association:
A positive Non-linear relationship between two variables can be shown with an upward-sloping curve in a graph.
Hence, Graph A represents the following relationship.
( Since graph B and D are linear and graph C is negative association since the value keeps on decreasing)
Test score will decrease because the graph shows negative association
Test score will increase because the graph shows positive association
Test score will increase because the graph shows negative association
Test score will decrease because the graph shows positive association
The correct answer is : Test score will decrease because the graph shows negative association.
Fact : Playing video games is a distraction and many kids fail there grade. Therefore test scores will decrease.
Part 2 : Non Linear: This can be defined as if all the points on the scatter diagram tends to lie near a smooth curve, the correlation is said to be non linear.
