Hi there!
We can begin by splitting the data into two equal parts, ignoring the median.
The median is simply the number in the middle of the data, or 5.
Now, we can split the data, taking the three left numbers and the three right numbers.
We have:
Left: 1, 3, 4
Right: 5, 7, 9
Find the medians of these sections. These are the middle numbers again, so:
Left: 3
Right: 7
These are our 1st and 3rd quartiles, respectively. The IQR is the difference between these, so:
7 - 3 = 4 = IQR.

Another contains 2 blue and 1 red .One ball is drawn from each bag
Find the probability
Both balls are white
The two balls are of the same color
The two balls are of different color
Answer:
two balls are of the same color
Step-by-step explanation:
5 blue and 3 red. so its not the same number of each. and there is no white balls.
Last year 123 students left a college with a pass in English.
This year 27 more students than last year left the college with a pass in English.
The college says
'The number of students leaving college with a pass in English has increased by 24% from last year!
(a) is the college correct?
Show why you think this.
Answer:
yes, (I think)
because 27 more students left this year with a pass and last year the percentage would of been lower I don't know
The college is incorrect, it is 28.125%
What is percentage?Percentage is defined as ratio expressed as a fraction of 100.
No. of students in college in last year = 123 -27 = 96
The number of students leaving college ratio = (27/96)×100%
⇒0.28125×100%
⇒28.125%
The college says,
'The number of students leaving college with a pass in English has increased by 24% from last year
Hence, The college is incorrect, it is 28.125%

A grocery store sells sliced turkey. The graph shows the relationship between the weight of the sliced turkey and the total cost of the sliced turkey. Two points, R and W, are labeled on the graph shown below.
Answer:
The correct option is ⇒ Point W means that that unit rate is $2.5 per pound.
Step-by-step explanation:
The question missing the graph and the options
The options for the questions are:
1) Point R means that that unit rate is $10 per pound.
2) Point R means that that unit rate is 4 pounds per dollar
3) Point W means that that unit rate is $2.5 per pound.
4) Point W means that that unit rate is 2.5 pounds per dollar.
And see the attached figure.
As shown in the figure attached
The unit rate will be the total cost per weight
By calculating the unit rate for the graph = (y2-y1)/(x2-x1)
using the given points (4,10) , (1,2.5)
the unit rate = (10-2.5)/(4-1) = 7.5/3 = 2.5
The unit rate means that it will cost $2.5 per pound and this is a gree with the point W which have the same meaning.
So, The correct answer is option 3.

The sum of three consecutive integers is -561. What are the
integers?
I
Answer:
-188, -187, -186
Step-by-step explanation:
x + (x+1) +(x+2) will usually be the formula for questions like this. If there wer 4 consecutive numbers, you just add (x+3) and so on.
The three integers are:
x + (x+1) + (x+2) Simplify this :
3x+3 = -561 Get 3x by itself, subtract 3 on both sides:
-3 -3
3x = -564 Find x divide -564 and 3:
x = -188
-188 is the first number now you count up.
-188 is the first number, -187 is the second, -186 is the third.
Hope this helps : )

solve this 28 - x = 24
Answer:
=> 28 - x = 24
=> x = 24 - 28
=> x = -4

if the circumfrence if a circular sheet is 154 then find the radius and area.
take π as 22/7
Answer:
1886.5
Step-by-step explanation:
2πr=154
2*22/7*r=154
44/7r=154
44r=1078
r=24.5
now,
area=πr²
=22/7*(24.5)²
=1886.5

Emilliano thinks x =40 is the solution to the equation 1/2 x =80. explain why he is wrong
Answer/Step-by-step explanation:
Given:
Emiliano thinks x = 40 is the solution to the equation 1/2x = 80
Note:
An equation is the statement that equalizes two mathematical expressions.
An expression is the combination of variables and constants connected with mathematical operations.
Solve:
Substituting the value of x, in the equation
1/2(4) = 80
20 ≠ 80
Thus, it isn't satisfied. Hence, Emiliano's answer is wrong.
Correct Way to Solve;
Multiply both sides by 2
2 · [tex]\frac{1}{2}x[/tex] = 80 · 2
Simplify
x = 160

Dan loves to compete in triathlons. At a race a few months ago, he finished in 300 minutes. Yesterday, he completed another triathlon and finished in 306 minutes. What was the percent of increase in Dan's finishing time?
Answer:
2%
Step-by-step explanation:
If 300 minutes is 100%, how much percent is 306 minutes?
we need to use the rule of three
306 minutes x 100% / 300 minutes = 102%
Therefore the percent of the increase is 102%-100%= 2%

Find the area of an equilateral triangle with a side length of 16 centimeters. Round to the nearest tenth.
As we know that the area of an equilateral triangle with side a is given by ;
[tex]{\boxed{\bf{Area_{(equilateral)}=\dfrac{\sqrt{3}}{4}a^{2}}}}[/tex]So , now using formula in our question, putting the value of the side, we can thus obtain
[tex]{:\implies \quad \sf Area=\dfrac{\sqrt{3}}{4}(16)^{2}}[/tex]
Putting value of √3 ≈ 1.73 and cancelling 4 we have ;
[tex]{:\implies \quad \sf Area\approx 1.73\times 64}[/tex]
[tex]{:\implies \quad \sf Area\approx 110.72\:\: cm^{2}}[/tex]
[tex]{:\implies \quad \sf Area\approx 110.7\:\: cm^{2}}[/tex]
