A, x-intercept is when y=0, so in this case when y=0, the equation becomes 5x=0. Therefore, x must equal 0 for 5x=0. so y=0 and x=0 so the answer it (0,0), which is A.
The mean could be used to describe a data set by itself, while interquartile range would almost never be used to describe a data set by itself.
<h3>What is Descriptive statistics?</h3>
These are operations which are used to summarize certain characteristics a set of data has.
Mean and range deals with the full set of data while interquartile range measures just the middle half of the data and is denoted as option A.

Answer:
length is 40 and breadth is 20
Step-by-step explanation:
120 =2( l + b )
120 = 2( 2x +x )
120= 2 x 3x
120 =6x
120/6 = x
20 = x
length=2x = 2 x 20 = 40
breadth= x = 20.

Answer:
v=8
Step-by-step explanation:
12=12+v−8/2
12=12+1/2
v+−4(Distribute)
12=(1/2v)+(12+−4)(Combine Like Terms)
12=1/2v+8
Step 2: Flip the equation.
1/2v+8=12
Step 3: Subtract 8 from both sides.
1/2v+8−8=12−8
Step 4: Multiply both sides by 2.
2*(1/2v)=(2)*(4)
v=8
Answer:
x=2.2582, y=19.91/9. (2.2582, 19.91/9).
Step-by-step explanation:
5x+4y=20.14
6x+7y=28.15
-------------------
6(5x+4y)=6(20.14)
-5(6x+7y)=-5(28.15)
------------------------------
30x+24y=120.84
-30x-35y=-140.75
--------------------------
-9y=-19.91
9y=19.91
y=19.91/9
5x+4(19.91/9)=20.14
5x+79.64/9=20.14
5x=20.14-79.64/9
5x=11.291
x=11.291/5
x=2.2582
