Step-by-step explanation:
As we know, the iqr is found by subtracting Q3-Q1. So that means we need to find them first. Finding the median will help us accomplish this task. So when writing out the numbers to solve it 81,82,83,83,84,84,84,85 because the amount of data points are an even number, we will have two data points which will help us solve our median which in this case is where the 83 and 84 meet. Our median is thus 83+84/2 which is 83.5. Now look on both sides of the two numbers which make up our median. On either side of the 2 data points needed for the median, the is another 3 data points. To find your q1 and q3, you need to find the median of these numbers. For Q1 look for the median between the numbers 81,82,83 and for Q3, look for the median in the numbers 84,84,85. So, knowing this information, our Q1 value is 82 and our Q3 value is 84. So..... input these into the equation we have up top which is Q3-Q1=IQR so...... 84-82=IQR, thus, our IQR is 2.

How much commission would a salesperson ear for selling a car that costs $29,389? He receives 16% commission on each sale.
Answers
Answer:
Commission on car = $4,702.24
Step-by-step explanation:
Given:
Sales price of car = $29,389
Commission on sale of car = 16% = 0.16
Find:
Commission on car
Computation:
Commission on car = Sales price of car x Commission on sale of car
Commission on car = 29,389 x 16%
Commission on car = 29,389 X 0.16
Commission on car = $4,702.24
Ancient slingshots were made form straps of leather that cradled a rock until it was released. One would spin the slingshot
in a circle, and the initial path of the released rock would be a straight line tangent to the circle at the point of release.
The rock will travel the greatest distance if it is release when the angle between the normal to the path and the horizontal
is -450. The center of the circular path is the origin and the radius of the circle measure 1.25 feet.
Write and equation of the initial path of the rock in standard form.
Answers
Answer:
Step-by-step explanation:∠ MON= -45°→→ angle lies in fourth quadrant.
Where, MN represents the path of rock, which is a straight line.
Taking the Horizontal and vertical component of OM,to get the coordinate of point M
The coordinate of point M will be [1.25 cos (-45°), 1.25 sin(-45°)]=
Taking O as center and Coordinates of O as (0,0) and Coordinates of M as () we get the equation of line OM as
y= tan (315°)× x
As general form of equation of line passing through the origin will be,
y= m x, where m is angle made by line with positive direction of x axis.
m= (360-45)°= 315°
→→y=-x
→→ y + x=0
equation of line perpendicular to OM will be
→→ x - y + k=0
Since it passes through .
→→
So, equation of initial path of stone will be:
Five years ago today, Artie was four times as old as his sister Carrie. In five years time, Artie will be twice as old as Carrie. Find their current ages using a system of linear equations.
Answers
Answer: 25 , 10 years
Step-by-step explanation:
Suppose the present age of Artie and Carrie is x and y
According to the question, 5 years ago
[tex]\Rightarrow x-5=4(y-5)\\\Rightarrow x-4y=-15\quad \ldots(i)\\[/tex]
In five year time
[tex]\Rightarrow x+5=2(y+5)\\\Rightarrow x-2y=5\quad \ldots(ii)[/tex]
Solving (i) and (ii) we get
[tex]x=25,y=10[/tex]
The current age of Artie and Carrie is 25 and 10 years

Step-by-step explanation:
2(6-4)+3=7
2(2)+3=7
4+3=7
7=7
Answer:
The answer is 6.
Step-by-step explanation:
2(x-4)+3=7.
1. Multiply the 2 by each number/variable inside of the parenthesis.
2x-8+3=7
2. Combine like terms
2x-5=7
3. Take the 5 from the left side and add it to 7 on the right side
2x-5=7
+5 +5
2x = 12
4. Divide both sides by 2
2x/2= X and 12/2 = 6
5. The 2 cancels out, leaving you with x, and 12 divided by 2 is 6.
X = 6

Water is filling a cylindrical water tank. As it is filled the radius of the tank expands at 0.2cm/s and the height decreases at the rate of 0.5cm/s. Find the rate at which the volume of the tank is changing at the instant the radius equals 1.8cm and height equals 65 cm. What is the volume of water at this point? Show all working. Volume, V, of the cylinder is given by V = ϖr2h.
Recall that V is a function of both r (radius of the cylinder) and h (the height of the cylinder). This is a partial differentiation problem. The volume is also changing with time.
Answers
Answer:
141.94 cm³/s
Step-by-step explanation:
Since the volume of the tank V = πr²h, and both the height and radius of the tank change with time, we find the rate of change of the volume with time, dV/dt from
dV/dt = dV//dr × dr/dt + dV/dh × dh/dt
where dV/dr = 2πrh, dr/dt = + 0.2 cm/s (since the radius of the tank expands), dV/dh = πr² and dh/dt = -0.5 cm/s (since the height of the tank decreases)
So,
dV/dt = dV/dr × dr/dt + dV/dh × dh/dt
dV/dt = 2πrh × + 0.2 cm/s + πr² × -0.5 cm/s
dV/dt = 0.4πrh cm/s - 0.5πr² cm/s
dV/dt = πr(0.4h - 0.5r) cm/s
We now find the rate at which the volume is changing when r = 1.8 cm and h = 65 cm.
So,
dV/dt = π(1.8 cm)(0.4 × 65 cm - 0.5 × 1.8 cm) cm/s
dV/dt = π(1.8 cm)(26 cm - 0.9 cm) cm/s
dV/dt = π(1.8 cm)(25.1 cm) cm/s
dV/dt = π(45.18 cm²) cm/s
dV/dt = 141.94 cm³/s
