The first quartile is 12. The median is 16!

Answer: 16

Step-by-step explanation:

  • The median is the middle number of a set of data  (if there are an odd number of data values) or the average of the two middle numbers (if there are an even number of data values).

  • A  box-whisker plot gives us information of the shape, variability, and median of a data set.

From the given box-whisker plot a vertical line goes through the box at 16 i.e. the median.

Hence, the median of the data set = 16.

puteri [66]

(4x−101)(2x+3)

Apply the distributive property by multiplying each term of 4x−101 by each term of 2x+3.

8x²+12x−202x−303

Combine 12x and −202x.

8x²−190x−303

If two cards are drawn without replacement from a 52 card deck, find the probability that the second card drawn is red, given th
snow_lady [41]

Answer:

The probability that the second card drawn is red, given that the first card was a heart is 0.1225

Step-by-step explanation:

Total cards in a deck = 52

Total red cards = 26

Heart cards = 13

Probability of getting red card =\frac{13}{52}

Total remaining card = 51

Remaining red cards = 25

Probability of getting red card in second draw without replacement = \frac{25}{51}

So, the probability that the second card drawn is red, given that the first card was a heart = \frac{13}{52} \times \frac{25}{51} =0.1225

Hence the probability that the second card drawn is red, given that the first card was a heart is 0.1225

Ira Lisetskai [31]

Answer:


Step-by-step explanation:

4/5 cup of brown sugar. Needs 1/4 cup. How many cups left?

Okay, so 4/5 = 0.80, 1/4=0.25.

0.80-0.25=0.55

Which is 55/100

Divide both numbers by 5

WLL GIVE BRAINLIST PLEASE help... i sincerely don't even know where to begin here. ​
Harman [31]

Answer:

y = 5

Step-by-step explanation:

WY is the perpendicular bisector of XZ and so divides ΔWXZ into 2 congruent triangles ΔWXY and ΔWZY

Hence WZ = WX ← corresponding sides, thus

5y - 8 = 2y + 7 ( subtract 2y from both sides )

3y - 8 = 7 ( add 8 to both sides )

3y = 15 ( divide both sides by 3 )

y = 5

Solve the system by substitution. x – 3y = 4 2x – 6y = 8 A. no solution B. x = 4, y = 0 C. x = 0, y = 0 D. infinite solutions
ruslelena [56]

Answer:

The correct answer is option D.

Step-by-step explanation:

if the pair of equation has one or more than one solution then it is said to be consistent.

  • Only one solution , then independent system.
  • More than one solution , then dependent system.

if the pair of equation has no solution then it is said to be inconsistent.

Given : x - 3y = 4 ...[1]

2x - 6y = 8 ...[2]

Solution :

Solving equations with the help of Substituting methods:

x - 3y = 4

x = 4 +3y

Putting value of x from [1] in [2]:

2(4+3y)-6y=8

8+6y-6y=8

6y=6y

0 = 0

Given , system of equation will have infinite solution. Hence consistent and dependent.

The given system of equations will have infinite solutions.
