Solution :
Median weight of a checked bag is= 27.5 pounds
it means , if there are n bags , the middlemost bag has weight 27. 5 pounds.
For , a data set, if it is symmetrical on both sides that is if difference between two succeeding values are same,then
Median = Mean
Otherwise , in some cases
Either, Median > Mean or Mean > Median.
Supposing each bag to be Equivalent, that is if they have equal weight,
Mean can't exceed ≥ 27.5 Pounds
Option B : The mean is most likely exactly 27.5 pounds, is true about the given statement The median weight of a checked bag is 27.5 pounds.
Thanks
Answer:
3) 361/11
4) 51
Step-by-step explanation:
for both problems, they give you the length of the segment so you just add both of the segments equal to the length of the whole segment. then for whatever you find as x, plug it into the equation.
ex. 7x+1+4x-3=42
or
5x-8+7x-12=10x-2
The \/````140 is between what two whole numbers?
11 and 12
B.
6 and 7
C.
4 and 5
D.
9 and 10
The coefficients in the expression are 3 and 7.
An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.
Now the given expression is,
9 - 4 + 3b + 7a
So, from the given expression we can see that there are 4 terms, 2 constants and 2 coefficients.
The coefficient of b is 3,
and coefficient of a is 7.
So, there are 2 coefficients in the given expression.
Thus, the coefficients in the expression are 3 and 7.

Answer:
f(A)= -143.75p + 4343.75
Step-by-step explanation:
Let price be x, and attendance, y
According to the given data,
admission was $17 the attendance was about 1900 customers
admission was $9 the attendance was about 3050 customers
Therefore, the points in terms of e and y coordinates would be , (17, 1900) --> (x1,y1)
& (9, 3050)---->(x2,y2)
Next is to calculate slope of linear equation i.e
m= (y2-y1)/(x2-x1)
m=(3050-1900)/(9-17)
m= -143.75
Now in order to find the equation, we use point-slope
y-y1= m (x-x1)
considering the coordinates (17, 1900) and slope -143.75
Equation becomes
y-1900 = -143.75( x- 17)
y-1900= -143.75x + 2443.75
y= -143.75x + 4343.75
or can be written as,
f(A)= -143.75p + 4343.75
Answer:
Step-by-step explanation:
From the question, A local cinema found that if the price of admission was $17the attendance was about 1900 customers per weekWhen the price of admission was dropped to $9. Attendance increased to about 3050 per week. Write a equation for the attendance in terms of the price. P i (A=mp+b )
Let price be a,and attendance, b
Attendance: 1,900 customers, when PRICE = $17
Attendance: 3,050 customers, when PRICE = $9
We then get the points,
(17, 1,900) & (9, 3,050)
Slope of linear equation,
(17,1900) (9, 3050)
find the slope m
(3050-1900)/(9 - 17)
1150/-8
-143.75=m
A=mp+b
A=-143.75p+b
using Attendance as a function of ticket price.
A(p) = mp + b
We have two points (p, A): (17, 1900), (9, 3050)
Slope: m = (2800-1500)/(7-17) = 1300/-10 = -130
A = -130p + b
Using (17, 1900) as (p, A) find b
1900 = -143.75(17) + b
1900 = -2443.75 + b
4343.75 = b
A = -143.75p + 4343.75
Answer:
47.5 per 1 lamp
Step-by-step explanation:
First, we can ignore the info about the department store because it is useless. Now, for the appliance store, we now that it sells lamps for 95 dollars per 2 lamps. 2 lamps equal 95, and it is asking how much does 1 cost. We can simply divide. So, 95/2= 47.5 dollars
A: n + n + 2 ≥ 80
B: n+ n + 2 > 80
C: n + n + 1 ≥ 80
D: n + n + 1 > 80
You can use the fact that the term "at least" means less than or equal to.
The inequality that models the given problem is given by
Option A: n + n + 2 ≥ 80
We can convert the descriptions to mathematical symbols.
There is sum of two consecutive odd integers.
Consecutive means near each other in numbers counting. Since they are odd, and consecutive, thus, with difference of 2.
Let first odd number be n, then other will be n+2
Their sum is n+n+2
It is at least 80 thus, 80 or bigger than that.
Thus,
n+n+2 ≥ 80
That symbol ≥ is called bigger or equal and it means left side is either bigger or equal to the right value.
Thus,
The inequality that models the given problem is given by
Option A: n + n + 2 ≥ 80
