The interqurtile range is q3 - q1
Q3 is 16.5 and the q1 is 12
16.5 - 12 = 4.5
Step-by-step explanation:
Answer is 4.5
Interquartile range (IQR) :
The interquartile range shows the range in values of the central 50% of the data. To find the interquartile range, subtract the value of the lower quartile ( or 25%) from the value of the upper quartile ( or 75%).
=> IQR = Q3 – Q1
Here,
First Arrange the data in ascending order.
11, 12, 12, 13, 14, 15, 16, 17, 18
Median = 14.
Q1 = 12 and Q3 = 16.5
IQR = Q3 - Q1 => 16.5 - 12 = 4.5
Answer is 4.5

X+30+x+10=180
combine like terms
2x+40=180
subtract 40 from both sides

A train travels 423 miles every 9 hours. What is the unit rate of the train?
Answer:
47 mph.
Step-by-step explanation:
The unit rate would be in mph.
Divide 423 miles with 9 hours:
423/9 = 47
47 mph, or miles per hour, is your answer.
~
Given that: Train travels 432 miles in every 4 hours
To Find: Unit rate of the train
⠀⠀⠀⠀⠀⠀__________________
Solution:-
we can find the unit rate of train by divide the distance and time.
⠀⠀
[tex]:\implies\sf{speed(v)} \: = \dfrac{distance(s)}{time(t)} [/tex]
[tex]:\implies\sf Speed\; (v) = \dfrac{423}{9}[/tex]

I need help with the first question pls
Answer:
67.5 feet
Step-by-step explanation:
If 1 inch = 9 feet, and the model is 7.5 inches,
you just need to do 7.5 • 9 = 67.5 feet.
OR
7 • 9 = 63 and 1/2 (or .5) • 9 = 4.5
63 + 4.5 = 67.5
*I'm pretty sure it says 1 inch = 9 feet and I'm also basing this off the fact that your work for question 2 is showing the same ratio of 1 inch = 9 feet

Answer:
y = 4x - 9
Step-by-step explanation:
y = 4x + 2
the the slope m is 4
the new line which paraller to the first one will have a slope 4 too
M = 4
then, the new slope-intercept form which pass through (x1,y1), in this case (5,-4) is
y - y1 = M(x - x1)
y - (-4) = 4(x - 5)
y + 4 = 4x - 5
y = 4x - 5 - 4
y = 4x - 9
Answer:
Step-by-step explanation:
FYI only
Slopes of parallel lines are the same and y-intercepts are different
( [tex]x_{1}[/tex] , [tex]y_{1}[/tex] )
y - [tex]y_{1}[/tex] = 4( x - [tex]x_{1}[/tex] )

Step-by-step explanation:
A simple way to remember the difference between greater than or less than is picturing the symbol as an alligator, the mouth of the alligator, the open end, eats the bigger number. The line under the greater than/ less than symbol means "or equal to". An open circle on a number line means that it's NOT "or equal to", so the answer isn't B or D. On the number line, it shows what x could equal. The arrow falls on 0, I'll use 0 as an example. Is 0 less than 5? Yes. If x could equal 0, that means that x is less than 5.

Jose had a rectangular piece of paper that
was 80 mm long and 70 mm wide. He cut
the paper in half. What is the area of each
half of the paper in square millimeters?
A. 5600 sq mm
B. 2800 sq mm
C. 140 sq mm
D. Not here
Answer:
B. 2800 sq mm
Step-by-step explanation:
Given the following data;
Length = 80 mm
Width = 70 mm
Area of rectangle is given by the formula;
Area of rectangle = length * width
Substituting into the formula, we have;
Area of rectangle = 80 * 70
Area of rectangle = 5600 mm²
Since the paper (area of rectangle) was halved, we would divide by 2;
Area of each half = 5600/2
Area of each half = 2800 sq mm.

(-3 + 4) x 66 + -19 x 8 - 2
Answer:
-88
Step-by-step explanation:
(-3 + 4) x 66 + -19 x 8 - 2
According to PEMDAS (or GEMDAS), you start with the parenthesis. So you do the equation in the parenthesis.
-3+4= 1
Now you replace it with your answer.
1 x 66 + -19 x 8 - 2
You next do multiplication.
1*66=66
66+ -19 x 8 -2
Multiplication again
-19*8=-152
66 + -152 - 2
Now there is only addition and subtraction left so you solve left to right.
66 + -152= -86
-86-2=-88
The answer is -88
From - 12 surface sea level, a submarine descends 20 feet per minute. Where is the submarine in relation to sea level 7 minutes after it starts descending?
Answer:
-152 feet in relation to sea level.
Step-by-step explanation:
If it descends 20 feet per minute, you just multiply the distance by the minutes. So 20x7 and you will get 140. You can't forget that it's already -12 below sea level, so it's 12 feet deeper. It's -152 feet in relation to sea level.

To find a pattern, look at the differences between
consecutive terms. These differences also form a
sequence.

Answer:
The sequence is 2, 4, 8, 16, 32
The next answer is 2
Step-by-step explanation:
The missing terms of the required sequence are 8, 16 and 32 respectively.
What is a geometric sequence?In a geometric sequence, the ratio of two consecutive terms are always equal.
The general expression for the nth term is given as aₙ = a₁ × rⁿ⁻¹ .
The sum of n terms for this sequence is given as Sₙ = (rⁿ - 1)/(r - 1)
The given sequence is 1, 3, 7, 15, 31, 63...
Then, the sequence formed by subtracting the consecutive terms are given as,
3 - 1, 7 - 3, 15 - 7, 31 - 15, 63 - 31 .....
Which can be rewritten as,
2, 4, 8, 16, 32......
It is a geometric sequence as ratio of the consecutive terms are equal,
4/2 = 8/4 = 16/8
Hence, the required sequence is a geometric sequence found as 2, 4, 8, 16, 32......
