The median of the data is 6 and the IQR will be 4.

<h3>What are median and IQR?</h3>

The median is the number separating the greater half from the lower half of a sample data in probability theory and statistics. The interquartile range is a measure of statistical dispersion, or the spread of the data, in descriptive statistics.

To calculate the median first arrange the data in the increasing order and then find the mid value.

3,4,6,6,6,8,9,9,12

The middlemost value will be the median.

Median = 6

To calculate the IQR convert the data into lower limits and the upper limits from the median and then calculate the IQR.

3,4,6,6,   |6|     ,8,9,9,12

Lower               Upper

Q1 = (4 + 6)/2 = 5

Q2 = ( 9+9)/2 = 9

IQR = 9 - 5 = 4

Therefore, the median of the data is 6 and the IQR will be 4.

2 angles measure 40 degrees each, what does the third angle measure? what type of triangle is it?
zimovet [89]

Answer:

Part a): 100 degrees

Part b): Isosceles Triangle

Step-by-step explanation:

Part a): Since the angle measures of all triangles add up to 180 degrees and since the other two angles are 40 degrees, which add up to 80, we can use subtraction to find the answer.

180 - 80 = 100

Part b): Since only two of the three angles in this triangle have the same measure, we can find that it is an isosceles triangle, with base angles measuring 40 degrees, and the vertex angle being 100 degrees.

Please show all work!! this is algebra.
Mnenie [13.5K]
Franco:
3x+2y=19
Caryl:
2x+4y=24

now use elimination

-2(3x+2y=19)
1(2x+4y=24)
=
-6x-4y=-38
2x+4y=24
add them together
which equals -4x=-14
divide both sides by -4
-4x/-4=-14/-4
x=7/2


we found x, so we subsitute it into the the original equation

3x+2y=19
3(7/2)2y=19
2y+21/2=19
-21/2 -21/2
2y=17/2
divide by 2 on both sides
2y/2= 17/2/2
y=17/4

so x= 7/2 and y= 17/4

Help me pleaseee I need help
MAVERICK [17]
I think it is b because probability of 2 is 1/6 then probability of 4 is 1/6. If you times them together 1/6x1/6 it will equal 1/36 so b
