[tex]Q_3-Q_1=Q_i[/tex]Answer:
The answer is 10. Frank has done more than Marquis by10.
Step-by-step explanation:
From the internet, the interquartile is Q_3-Q_1=Q_inter
From Marquis his Q_3 = 40 and Q_1 = 20
[tex]Q_3-Q_1=Q_i[/tex]
40-20=20
From Frank his Q_3 = 40 and Q_1 = 10
[tex]Q_3-Q_1=Q_i[/tex]
40-10=30
Frank's interquartile is 30 and Marquis interquartile is 20.
Differences between the both of them.

The circumference of a circle is 20pi in. What is the area, in square inches? Express
your answer in terms of Pi
Answers
Answer:
10.14π
Step-by-step explanation:
First we have to work backwards. We know the forumla for circumference is pi x diameter. So we have to work backwards. 20 divided by pi is 6.37. So thats our diameter. Now that we that we can put it into our forumla for area. A= π x R^2.
The raidus is half of the diamater so 6.37/2. Which equals 3.185. Now we that into our formula. A= π x 3.185^2. Now we keep simplyifying the equation. 3.185^2=10.14. So now we have A=10.14π

Answers
Step-by-step explanation:
you have to be careful with the precise notation of terms and expressions.
you keep using only -7 for everything.
i suspect you mean 7 and -7, right ?
if that is correct, then just remember this :
on a number line the positive values are on the right, and the negative values on the left.
in fact, the further right you go, the larger the number gets. and the further left you go, the smaller (or lower) the number gets.
e.g. -7 is smaller than -6.
and so, -7 would be to the left of 7, because -7 < 7.
or vice versa :
7 would be to the right of -7, because 7 > -7

Answer:
A: Second option

Step-by-step explanation:
PART A
The second option
0.40c(0.15) + 0.60c(0.20)
If we have 40% men, and 15% of them are advanced
we can say 40% x 15% x c which is the same as 0.40 x 0.15 x c
Same thing for the women
0.60 x 0.20 x c
PART B
0.40c(0.15) + 0.60c(0.20)
= 0.06c + 0.12c
= 0.18c which is the same as 18% of c

Why is this equation: [tex]\frac{(x-2)^{2}}{24} + \frac{(y+5)^{2}}{29}=1[/tex] an ellipse and not a circle?
Usually, you can tell if it's an ellipse because the coefficients of x and y are different. Here, though, they're the same, yet every website is telling me it's an ellipse and not a circle. Why is that?
THANKS!
Answers
well, your observation is correct, for the form
Ax² + Bx + Cy² + Dy + E = 0if the coefficients are the of x² and y² are different and the same sign then we have an ellipse, hmmm I usually see a circle as an ellipse with equal major and minor axes, because is basically just that.
However, the rational form you have is that of an ellipse indeed, we can change it about to the form above and you'll see it so.
Just bear in mind that for the rational form for conics
if both fractions are positive and their denominator different, is an ellipse
if both fractions are positive and their denominator equal, is a circle
if one of the fractions is negative, then we have a hyperbola, and on a hyperbola the traverse axis is always the denominator with the positive fraction, so if the denominator is under the "x" fraction, then the traverse axis is horizontal, if under the "y" fraction, then vertical.
based on that fraction, is an ellipse with a center at (2 , -5).
now, the larger denominator is 29 and it's under the "y" variable, that means the major axis is in the direction of the y-axis, so is a vertical ellipse if you wish. Check the picture below.

Step-by-step explanation:
For triangle:
[tex]Base\: (b) = x^{\frac{1}{2}}\: m\\\\Height \:(h) = x^{\frac{3}{4}}\: m\\\\ A(\triangle)= 16\:m^2\\\\A(\triangle)= {\frac{1}{2}}(b)(h)\\\\\implies 16=\frac{1}{2}(x^{\frac{1}{2}})(x^{\frac{3}{4}})\\\\\implies 32= (x^{\frac{2}{4}})(x^{\frac{3}{4}})\\\\\implies 2^5=x^{\frac{3+2}{4}}\\\\\implies 2^5=x^{\frac{5}{4}}\\\\\implies 2=x^{\frac{1}{4}}\\\\\implies 2^4=x\\\\\implies x=16\:m[/tex]
[tex]Base\: (b) = x^{\frac{1}{2}}={16}^{\frac{1}{2}}={(4^2)}^{\frac{1}{2}}=4\: m[/tex]

What is the perimeter of triangle ron? 10.0 units 15.0 units 18.7 units 23.7 units
Answers
The perimeter of the triangle RON is the sum of the side lengths
The perimeter of the triangle is 15 units
How to determine the perimeter of triangle?From the question, we have:
ON = 5 units
Side lengths ON and OR are radii of the circle O.
So, we have:
OR = ON = 5 units
The chord RN has a length of 5 units.
So, the perimeter of the triangle is:
P = OR + ON + RN
This gives
P = 5 + 5 + 5
Evaluate
P = 15 units
Hence, the perimeter of the triangle is 15 units

A cylinder has a base radius of 4m and a height of 6m. What is its volume in cubic m, to the nearest tenths place?
Answers
301.6 cubic meters
Step-by-step explanation:A cylinder is a shape with straight sides with circular or oval cross-sections. We know that the cylinder in the question must be a circular cylinder due to its radius description.
Volume Formula
A circular cylinder has a volume of [tex]V=\pi r^2h[/tex]. In this equation, V is the volume, r is the radius, and h is the height. The question tells us that r=4m and h=6m. So, we can plug these values into the formula.
Solving for Volume
To solve plug the values into the formula and rewrite the equation.
[tex]V=\pi *4^2*6[/tex]Next, apply the exponents.
[tex]V=\pi *16*6[/tex]Then, multiply the constants.
[tex]V=\pi *96[/tex]Finally, multiply the remaining terms. Remember to use the pi button on the calculator and not an estimation to get a more exact value.
[tex]V=301.6[/tex]Make sure your answer is rounded to the correct digit. This means that the volume must be 301.6 cubic meters.

Z = 2x + 3y
The constraints are given as:
3x+2y≤15
4x+y≤0
x≥0; y≥0
See attachment for the graph of the constraints
From the attached graph, we have the optimal solution to be:
(x,y) = (-3,12)
Because x≥0 & y≥0, and x is negative in (-3,12), then
The function cannot be maximized.
Part B (Question 7): Maximize ZThe objective function is given as:
Z = 2x + 5y
The constraints are given as:
x + y ≤ 5
y - x ≤ 1
x≥0; y≥0
See attachment for the graph of the constraints
From the attached graph, we have the optimal solution to be:
(x,y) = (2,3)
Substitute 2 and 3 for x and y in the objective function.
Z = 2 * 2 + 5 * 3
Evaluate
Z = 19
