Answer:
The relation for the distance cover by Tina and Lia is 20 = 4 × m
Option B
Step-by-step explanation
Given as :
The distance cover by Tina = = 20 miles
The distance cover by Lia = = m miles
According to question
Tina walked 4 times as far as Lia
So, The distance cover by Tina = 4 × The distance cover by Lia
Or, = 4 ×
I.e 20 miles = 4 × m miles
or. 20 = 4 × m
So, relation is 20 = 4 × m
Hence, The relation for the distance cover by Tina and Lia is 20 = 4 × m
I.e option B Answer
Most likely the numbers of red beads in the bag are 20.
Let us consider there are x red beads and (50-x) yellow beads.
So, as given in the question, Jake pulls a total of 15 beads(6 red and 9 yellow).
So, P(r)=ed bead probability
and yellow bead probability
Now, the total number of red bead
Hence, the number of red beads in the bag is most likely to be 20.
Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur i.e. how likely they are to happen, using it.
The probability of an event can be calculated by probability formula by simply dividing the favorable number of outcomes by the total number of possible outcomes.
Example: toss a coin 100 times, how many Heads will come up? Probability says that heads have a ½ chance, so we can expect 50 Heads. But when we actually try it we might get 48 heads, or 55 heads ... or anything really, but in most cases it will be a number near 50.

Answer:
30 different signals
(n = no. of objects)
(r = no. of objects selected)
Step-by-step explanation:
this is a permutation problem so use the formula:
5P5 / 2! 2! 1! <- its 5 P 5 because there are 5 flags, 2 red, 2 white, and 1 blue
[5! / (5 - 5)!] / 2 x 2 x 1 <- the permutation formula is: n! / (n - r)!
= 120 / 4
= 30
