The effect of eliminating the lowest value, 0, from the data set have on the mean and median of the data set is;
There is a difference of 7.5 between the mean without 0 and mean with 0There is a difference of 2.5 between the median without 0 and median with 0What is mean and median?The mean of a given data is the sum of all observations divided by the number of observations
The median of a given set of data refers to the middlemost observation, obtained after arranging the data in ascending or descending order.
Given data:
0, 40, 60, 70, 75, 80, 85, 95, 95, 100
a) Mean without '0' = (40+ 60+ 70+ 75+ 80+ 85+ 95+ 95+ 100) / 9
= 700/9
= 77.777
Median without '0' = 40, 60, 70, 75, 80, 85, 95, 95, 100
= 80
Mean with ' 0' = 0+ 40+ 60+ 70+ 75+ 80+ 85+ 95+ 95+ 100 / 10 = 70
Median with '0' = 0, 40, 60, 70, 75, 80, 85, 95, 95, 100
= (75 + 80) / 2
= 77.5
So therefore,
Difference in mean = Median without '0' - Mean with ' 0'
= 77.77 - 70
= 7.7
Difference in median = Median without '0' - Median with '0'
= 80 - 77.5
= 2.5

A set of weights includes a 20 lb barbell and 6 pairs of
weight plates. Each pair of plates weighs 30 lb. lfx
pairs of plates are added to the barbell, the total weight
of the barbell and plates in pounds can be represented
by f(x) = 30x + 20.
This graph represents a continuous function. Also, the domain of this function is 0 ≤ x ≤ 6 and the range of this function is 20 ≤ y ≤ 200.
What is a range?Mathematically, a range can be defined as the set of all real numbers that is associated with the elements of a domain. This ultimately implies that, a range simply refers to the set of all possible output numerical values which are shown on the y-coordinate (y-axis) of the graph of a function.
What is a domain?In Mathematics, a domain can be defined as the set of all real numbers for which a particular function is defined and it connects with the range.
This ultimately implies that, a domain is the set of all possible input numerical values to a function. Additionally, the domain of the graph of a function comprises all the input numerical values which are shown on the x-coordinate (x-axis).
From the information provided, the total weight of the barbell and plates in pounds is represented by this function:
f(x) = 30x + 20.
When x = 6, we have:
f(6) = 30(6) + 20.
f(6) = 180 + 20
f(6) = 200 lb.
Therefore, the domain is equal to 0 ≤ x ≤ 6 while the range of this function is 20 ≤ y ≤ 200.

a police car is located 70 feet to the side of a straight road. a red car is driving along the road in the direction of the police car and is 90 feet up the road from the location of the police car. the police radar reads that the distance between the police car and the red car is decreasing at a rate of 75 feet per second. how fast is the red car actually traveling along the road?
The speed of 213.25 mph is the red car actually traveling along the road.
What is speed?
The definition of speed is the pace of movement of an object (covering a particular distance). It defines only the magnitude and not the direction, making it a scalar quantity.
The meter per second (m/s) unit of speed is taken from the SI.
let distance between the police and red cars = h
distance from the red car to a point horizontal to the police car = a
distance from from the road to the police car = b
=>[tex]h^2=a^2+b^2[/tex]
take the derivative with respect to time
=>hh' = aa' + bb' b'=0
=>174.64(75) = 90a'
=>a' = 174.64(75)/90 = 145.4ft/sec
=>145.4ft/sec = 145.4(5280)/60^2 = about 213.25 mph
Here ,1 mile = 5280 feet
=>1 hour = 60 minutes x 60 seconds = 3600 seconds
=>1 mile per hour = 5280 feet per 3600 seconds
=>1 foot per second = 5280/3600 mph = 1.4666...mph
=>145.4x 1.4666... = 213.25 mph
Hence 213.25 mph speed is the red car actually traveling along the road.

A pharmacist wants to mixture of 40 % saline solution with a 12% saline solution to get 119 ml. of a 32% saline solution. He used 85 ml of 40% saline solution and 34 ml of 12% saline solution.
Define mixture.Mixture word problems require you to combine two or more separate items, and then calculate some quantity of the resulting mixture (such as a percentage, price, or number of liters, for example). There will always be some type of "rate," like miles per hour or price per pound. Mixtures are substances that contain two or more distinct substance categories. To separate them, utilize physical tools. Examples include air, different gases, a mixture of sugar and water, a solution of salt and water, and so on.
Given,
A pharmacist wants to mixture of 40 % saline solution with a 12% saline solution to get 119 ml. of a 32% saline solution.
Equation:
X + y = 119
y = 119 - x
0.40x + 0.12y = 119 of 0.32
0.40x + 0.12y = 38.08
Using y = 119 -x
0.40x + 0.12(119 - x) = 38.08
0.40x + 14.28 - 0.12x = 3808 Eq(2)
0.28x = 23.8
x = 85
y = 119 - 85
y = 119 - 85
y = 34
Equating values in equation (2),
0.40(85) + 0.12(34)
34 + 4.08
38.08

What is percentage?A percentage is just one of the many ways that a number, ratio, or fraction can be expressed. It is a number or ratio expressed as a fraction of 100.
Given:
Sherry has 15200$ to invest in mutual funds and in bonds.
Sherry has selected a mutual fund that earns 1% a year and a bond that earns 4% a year.
Here we need to find how much does she need to invest in each type of account if she wants to earn 548 at the end of the first year.
Here we have total amount = 15200$
So, let us consider x be the amount invested in mutual funds, then the amount invested in bonds will be 15200 - x.
It can be written in the following matrix
[x 15200-x ]
We know that the total amount earned at the end of the year is 548.
So, it can be written as
amount invested x percentage = final amount
[tex]\left[\begin{array}{cc}x&15200-x\\\\\end{array}\right][/tex]*[tex]\left[\begin{array}{ccc}1/100\\4/100\\\end{array}\right][/tex] = 548
We can simply it as
[x*1/100 + (15200 - x)*4/100] = 548
⇒ x/100 + 60800/100 - 4x/100 = 548
⇒ x + 60800 - 4x = 54800
⇒ -3x = 54800 - 60800
⇒ -3x = -6000
⇒ x = 2000
⇒ 15200 - 2000 = 13200
Therefore, Sherry invests 2000$ in mutual funds and 13200$ in bond to earn 548 at the end of the year.

(1 point) the radius of a right circular cone is increasing at a rate of 5 inches per second and its height is decreasing at a rate of 3 inches per second. at what rate is the volume of the cone changing when the radius is 20 inches and the height is 40 inches?
The rate of change of volume is 418.6 inch³/s .
Rate of increase of radius with time is ( dr/dt ) = 5
rate of decrease of height with time is (dh/dt ) = -3
volume of a cone is given by (V) = [tex]\frac{1}{3} \pi r^{2}h[/tex]
Now the rate of change of volume with respect to time is given by dV/dt
∴ dV/dt = d( [tex]\frac{1}{3} \pi r^{2}h[/tex]) / dt
dV/dt = [tex]\frac{1}{3} \pi (2rh\frac{dr}{dt} + r^{2}\frac{dh}{dt} )[/tex]
value of radius and height when volume is changing are :
r = 20 inches
h = 40 inches
dV/dt = [tex]\frac{1}{3} \pi ([/tex] 2×20×40 ×5 - [tex]20^{2}[/tex]×3 )
dV/dt = [tex]\frac{1}{3} \pi[/tex](1600 - 1200)
dV/dt = (400/3) 3.14
dV/dt = 418.66 inch³/s
So the rate of change of the volume is 418.66 inch³/s.

Or the greenville tigers are having team shirts made. one option is to pay anthony's tees a $40 setup fee and then buy the shirts for $6 each. another option is to go to city printing, paying $20 for a setup fee and an additional $10 per shirt. the team parent in charge of the project notices that, with a certain number of shirts, the two options have the same cost. what is the cost?
The total cost of the shirts that have same cost when x=5 is,
c=70
What is an equation?A mathematical equation is a formula that joins two expressions and expresses their equivalence using the equals symbol (=). The definitions of the word equation and its cognates in different languages may differ slightly.
The entire cost is c
c = 40 + 6x
c = 20 + 10x
The quantity of shirts is x.
Via utilizing one of the equations to solve for one of the variables and then substituting that variable's value into the other equation, you can solve by substitution.
40+6x=20+10x
4x=20
x=5
You would solve for c in the first equation in this problem.
40+6x where x=5 then,
c=70
Since it has already been solved for c, all that is left to do is swap out c with its equivalent in the second equation.
20+10x where x=5 then,
c=70
Therefore, the total cost of the shirts that have same cost is c=70 when x=5.

in a class of 150 students the ratio of boys to girls is 3 2 how many more boys than girls are in the class
The number of boys and girls in a class of 150 students is 90 and 60 respectively.
RATIO:
Comparing two quantities of the same units and determining the ratio tells us how much of one quantity is in the other.
i.e., it shows how many times a number contains another.
Total number of students = 150
ratio of boys to girls = 3 : 2
B:G = 3 : 2
now
3x + 2x = 150
5x = 150
x = 30
the number of boys = 3x = 3 X 30 = 90 boys.
the number of girls = 2x = 2 X 30 = 60 girls.
The number of boys and girls in a class of 150 students is 90 and 60 respectively.
