Which statements about the box plot are correct? Check all that apply. Fifty percent of the data values lies between 34 and 46.
Art [367]

Answer:

Option 1 and 3 are correct which indicate that fifty percent of the data values lie between 34 and 46, and it is unlikely there are any outliers.

Step-by-step explanation:

As the plot is not given, by an online search, same question is found online for which the plot is given as attached herewith.

From the box plot:

median=46

Q1=42

Q3=70

Q3-Q1= IQR=70-42=28

max=76

min=34

Range=max-min=76-34=42

no outliers seen from boxplot

only (1)and (3)are correct.

Select the correct answer. Which expression is an equivalent expression of 12x + 10 + 4y? 2(6x + 2y + 6) 3(4x + y + 10) 2(6x + 4
Illusion [34]
The answer would be 2(6x+5+2y) you can figure this out through the distributive property. 2(6x)=12x 2(5)=10 and 2(2y)= 4y this would reult in giving you the equation 12x+10+4y
