Which of the following accurately describes the median of a set of data? Multiple choice question. The midpoint of the data when it is arranged in order. The difference in the largest and smallest values. The most numerous observation in a set of data. The arithmetic average of the values in the set.
Answer:
The midpoint of the data when it is arranged in order.
Step-by-step explanation:
Median can be described as the number that occurs in the middle of a set of numbers that are arranged either in ascending or descending order
For example, the median of the following set of numbers is 5
1, 2, 5, 10, 20
Range is the difference between the highest and lowest values of a set of observations
Range = highest value - lowest value
Mean is the average of a set of numbers. It is determined by adding the numbers together and dividing it by the total number
Mean = sum of the numbers / total number
Charlotte volunteered to deliver dinners for seniors. The supervisor told her to take half the meals to Oak Hill Senior Center, one-fourth of them to the Glenview Apartment complex, and one-fifth of them to North-side neighborhood center. Unfortunately, there were 19 meals, which didn’t divide evenly as mandated. How could Charlotte follow the supervisor’s instructions without splitting apart any meals?
Answer:
Charlotte should take 5 meals to Glenview Apartment complex, 4 meals to North-side neighborhood center and 10 meals to Oak Hill Senior Center
Step-by-step explanation:
The given number of meals = 19 meals
The fraction of the meals to be taken to Oak Hill = (1/2)
The fraction of the meals to be taken to Glenview Apartment = (1/4)
The fraction of the meals to be taken to North-side neighborhood = (1/5)
Let A represent an even number of meals, we have;
The total meals she delivers = (1/2)·A + (1/4)·A + (1/5)·A = (19/20)·A
The remaining meals = A - (19/20)·A = (1/20)·A
Therefore, if the meals where 20, she would have an excess of 1 meal left
Therefore, the number of meals she can share using the given fractions = 19 meals
Therefore;
The number of whole meals she can take to Glenview = 20×(1/4) meals = 5 meals
The number of whole meals she can take to North-side neighborhood = 20 × (1/5) meals = 4 meals
Therefore, the number of meals she would take to Oak Hill Senior Center = (20 - 5 - 4) meals = 10 meals
The slope and y-intercept of the line y+px+q=0 are -2 and 5 respectively. Find p and q. Thank you!
Answer:
p = 2, q = - 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
y + px + q = 0 ( subtract px + q from both sides )
y = - px - q ← in slope- intercept form
with slope m = - p = - 2 ( multiply both sides by - 1 )
p = 2
and y- intercept = - q = 5 ( multiply both sides by - 1 )
q = - 5

Line AB contains points A(4, 5) and B(9, 7). What is the slope of ?
Answer:
2/5
Step-by-step explanation:
We can find the slope by using the slope formula
m = ( y2-y1)/(x2-x1)
= ( 7 -5)/(9 - 4)
= 2/5
Can someone help me with this math problem please?
Answer:
C
Step-by-step explanation:
g(x) is larger than f(x) and not the same size so B and D are out of question because those are translation not dilation.
f(x) is stretched in the vertical direction to get g(x). So this means the scale factor has to be greater than 1. so A is wrong.
The answer is c

A storage drum has a diameter of 7 feet and a height of 4 feet 3 inches how many gallons of chemicals cleaner can this drum hold
Answer:
The answer is "1223.42 gallons".
Step-by-step explanation:
Given:
[tex]Diameter\ (d)= 7\ feet\\\\r=\frac{d}{2}=\frac{7}{2}=3.5\ feet\\\\h= 4\ feet\ 3\ inches\ = 4.25 \ feet \\\\[/tex]
Using formula:
[tex]Volume = \pi r^2h[/tex]
Put the value into the above formula:
[tex]= \pi (3.5)^2 (4.25)\\\\= 3.14 \times12.25\times (4.25)\\\\= 3.14 \times 52.0625 \\\\=163.47625\\\\= 163.56 \ feet^3\\\\= 163.56 \ feet^3[/tex]
[tex]\therefore \\\\1 \ foot^3 = 7.48051945\ US\ gallons\\\\[/tex]
Final answer:
[tex]\to (163.56)(7.48) = 1223.42\ gallons[/tex]

Which graph represents the following piecewise defined function? g(x) = 1/2 x +3 , x< -2 g(x) = 2, -2<_ x <_3 g(x) = 2x-3 , x>3
In this question, a piece-wise function is asked to be graphed.
Piece-wise function:
A piece-wise function is a function that has different definitions, depending on the input.
In this question, the function has three different definitions:
When x is less than -2, the definition is:
[tex]g(x) = \frac{x}{2} + 3[/tex]
When x is between -2 and 3, inclusive, the function is:
[tex]g(x) = 2[/tex]
When x is greater than 3, the definition is:
[tex]g(x) = 2x - 3[/tex]
The graphic is given by the image at the end here, with the closed circle indicating the inclusive on the intervals.

find the coordinates of the points which divide the join X(-1,7) and Y(4,-3) in the ratio of 7:2.
Answer:
(26/9 , -7/9)
Step-by-step explanation:
Here,
let the points be
X(-1,7) = (x1, y1)
Y(4,-3) = (x2,y2)
and let the ratio be...
m:n = 7:2
and.. let the point that divides the line be
P(x,y)
now using the section formula for internal division..
P(x,y) = ( m.x2 + nx.1 / m+ n , my2+ny2/m+n )
= ( 7.4+2.-1 / 7+2 , 7.-3 + 2.7/7+2 )
= ( 26/9 , -7/9 )

Solve x^2−4x−12=0 by completing the square. PLEASE HELP QUICK WILL GIVE BRAINLIEST
Answer:
The answer is B
Step-by-step explanation:
If u use calculator,u will get the ans as x¹=6 and x²= -2 but u have to change it to the opposite which means negatif to positive(-2=2) and positive to negative(6= -6).Hope u can understand...sorry,English isn't my first language
Answer:
x= 6 and x=-2
Step-by-step explanation:
find the two factors that when multiplied will get -12 and when summed up will get -4.
so -6 and 3
(xsquare-6) +(2x -12)=0
x(x-6)+2(x-6)=0
(x-6)=0 (x+2)=0
group like terms
x=6. x=-2

Gerald and ben shareda sum of money. Gerald took $51 more than 2/7 of the money. Ben took $30 less than gerald. What was the sum of money
Answer:
$168
Step-by-step explanation:
let x = total sum of money shared
Amount Gerald took = 51 + [tex]\frac{2}{7} x[/tex]
Amount Ben took = (51 + [tex]\frac{2}{7} x[/tex]) - 30
= 21 + [tex]\frac{2}{7} x[/tex]
(51 + [tex]\frac{2}{7} x[/tex]) +( [tex]21 + \frac{2}{7}x[/tex]) = x
combine like terms
51 + 21 = x - ([tex]\frac{2}{7} x + \frac{2}{7} x[/tex])
72 = x - 4/7x
72 = 3/7x
divide both sides of the equation by 7/3
x = $168

She has 2/3 of a kilogram of bird seed left. How many cages can she refill with bird seed?
Answer:
She can refill 2 cages.
Step-by-step explanation:
Since Megan puts 1/3 of a kilogram of bird seed in each bird cage, she can fill 2 cages.
Answer: she can fill 2 times the amount of cages she has.

y-3=2(x-3) y+5=2(x+1)
choose 1 answer
the same line
distinct parallel lines
Perpendicular lines
intersecting, but not perpendicular lines
Answer:
The same lines (answer)
Step-by-step explanation:
The equations can be written in slope-intercept form y = mx + c (where 'm' is slope and 'c' is the y-intecept) as,
y-3 = 2(x-3) .......(1) ; y + 5 = 2(x+1) ...........(2)
y = 2x - 6 + 3 ; y = 2x + 2 - 5
y = 2x -3 ; y = 2x - 3
Comparing with slope intercept form we have,
m1 = 2 ; m2 = 2
c1 = -3 ; c2 = -3
If the slopes are equal the lines are parallel and since y-intercepts are also equal means they are the same lines (overlapping)
A jar is filled with 74 different colored marbles, 10 of which are red, 38 of which are blue, and 26 of which are green. A player is asked to draw a single marble from the jar and if they draw a red marble they will win $20, if they draw a blue marble they will lose $10, and if they draw a green marble they will lose $5. You may round your answer to the nearest cent
Solution :
Colored marble Prize
Red ---- 10 20
Blue --- 38 10
Green --- 26 5
P(red) = 10/74 = 5/37
P(blue) = 38/74 = 19/37
P( green) = 26/74 = 13/37
Therefore,
X → Red Blue Green
P(X) 5/37 19/37 13/37
The expected values are :
[tex]$20 \times \frac{5}{37} - 10 \times \frac{19}{37} - 5 \times \frac{13}{37}[/tex]
= -4.189

Answer:
b<4
Step-by-step explanation:
- 3b-5> - 8 or b - 4 < 0
Solve the first inequality
- 3b-5> - 8
Add 5 to each side
- 3b-5+5> - 8 +5
-3b> -3
Divide by 3, flipping the inequality
-3b/-3 < -3/-3
b <1
Then solve the second inequality
b-4<0
Add 4 to each side
b<4
Put them back together
b<1 or <4
Merge them since they overlap

What sum of money amount to Rs 6000 in two years at the rate of 10% per annum find it
Answer: Rs 5000 sum of money amount to Rs 6000 in two years at the rate of 10% per annum.
Step-by-step explanation:
Amount = Rs 6000
T = 2 year
R = 10%
So
I = A-P
so
I = PTR/100
or, A-P = (P*2*10)/100
or, 6000-P = 20P/100
or, 600000-100P = 20P
or, 600000 = 120P
or, P = 600000/120
so, P = Rs 5000
