Answer:
i would say its b
Step-by-step explanation:
Answer:
(1, -1), (1, -2), (2, -3), (2, -4)
NO
Step-by-step explanation:
✔️Each ordered pair is written as (input, output).
Thus, we would have the following:
(1, -1), (1, -2), (2, -3), (2, -4)
✔️This cannot be a function because every input value do not have exactly one output value related to it. A function should not have an input value related to more than one output value.
So, the answer is NO. It is not a function.
The answer is p = -8/15
Proportion can simply be defined as equating two ratios
The proportion of 3/2 = 4/p +9 can be calculated as follows
3/2 - 9/1 = 4/p
-15/2 = 4/p
cross multiply both sides together to find the value of p
-15×p= 4×2
-15p= 8
p= -8/15
Hence the answer is p= -8/15

#SPJ1
The answer is: the average height is

, the median height is r-2.
r - Ray's height
l - Lin's height
s - Sam's height
<span>Ray is 2 inch taller than Lin: r = l + 2 </span>⇒ l = r - 2
Ray is 3 inch taller than Sam: r = s + 3 ⇒ s = r - 3<span>
</span><span>The average is the sum of all values divided by the number of values:
</span>

<span>
Since </span>l = r - 2 and s = r - 3, then:

<span>The median means the middle value. Let's first rearrange values so we can find the middle one:
</span>Ray is taller than Lin and Sam, so Ray is the tallest.
Sam is much shorter than Ray comparing to Lin, so Sam is the shortest.
Therefore, values are from the lowest to the highest:
(s, l, r)
⇒ (r-3,
r-2, r)
Median of these values is in the middle, so the median height is r-2.
Answer: P(A∪B) = 1/3
Step-by-step explanation:
Red Garments = 1 red shirt + 1 red hat + 1 red pairs of pants
Total Red Garments = 3
Green Garments = 1 green shirt + 1 green scarf + 1 green pairs of pants
Total Green Garments = 3
The total number of garments = Total Red Garments + Total Green Garments:
3 + 3 = 6
Let A be the event that he selects a green garment
P(A) = Number of required outcomes/Total number of possible outcomes
P(A) = 3/6
Let B be the event that he chooses a scarf
P(B) = 1/6
The objective here is to determine P(A or B) = P(A∪B)
Using the probability set notation theory:
P(A∪B) = P(A) + P(B) - P(A∩B)
P(A∩B) = Probability that a green pair of pant is chosen = P(A) - P(B)
= 3/6-1/6
= 2/6
P(A∪B) = 1/2 + 1/6 - 2/6
P(A∪B) = 2/6
P(A∪B) = 1/3
I hope this helps. :)
