Answer: 6

Step-by-step explanation:

4+(9 x 2) / (4-1)-4=6

Calculate within parentheses (9 x 2) : 18

= 4+18 / (4-1) -4

Calculate within parentheses (4-1) : 3

=4+8 / 3-4

Multiply and divide (Left to right) 18 / 3 : 6

= 4+6-4

Add and subtract (left to right) 4+6-4 : 6

Answer:

Step-by-step explanation:

Use PEMDAS

P = parenthesis

E = Exponents

M = Multiplication*

D = Division*

A = Addition**

S = Subtraction**

*either can come first, it just depends which comes first in the equation.

**either can come first, it just depends which comes first in the equation.

Step 1 : Write equation 4( 9 × 2 ) ÷ ( 4 -1 ) - 4

Step 2: Solve in parenthesis 4(18) ÷ (3) - 4

Step 3: Solve multiplication  72 ÷ 3 - 4

Step 4: Solve division 24 - 4

Step 5 : Solve subtraction 20

Which box plot correctly displays the data set with a maximum of 48, a minimum of 27, a median of 36, an upper quartile of 45, a

Answer:

Image 1

Step-by-step explanation:

To answer this question, we need to know how to use a box plot.

I've attached an image that demonstrates this well and can teach you what each part of the box plot means.

Specifically, the 2 farthest dots at the end are the minimum and maximum. The two sides where the box starts are the lower and upper quartiles. Finally, the line in the middle of the box is the median.

With this, we can analyze each box plot and determine which one is correct.

Box Plot 1: Everything is plotted correctly- Maximum and minimum plotted correctly, median plotted correctly, upper and lower quartile plotted correctly.

Box Plot 2: Everything plotted correctly EXCEPT maximum of 48 is represented at 46.

Box Plot 3: Everything plotted correctly EXCEPT the upper quartile of 45 is at 39.

Box Plot 4: Upper quartile represented at 39 and maximum represented at 46 are both incorrect.
