Answer:
A. 4.5
Step-by-step explanation:
You can find the center value (median) either by crossing off a box from the lower number end and one off the higher number end until you find the middle value, or by writing them out and doing the same.
2, 3, 3, 3, 3, 4, 4, 4, 4, 4, 5, 5, 5, 5, 6, 6, 7, 8, 9, 10
Since there are 20 numbers, there are two center numbers, 4 and 5. So we take the average of them, which is 4.5

Step-by-step explanation:
Given
[tex]\begin{array}{cccccc}{Size & {1} & {2} & {3} & {4} & {5} \ \\ {f} & {3} & {4} & {6} & {7} & {5} \ \end{array}[/tex]
Required
The percentage of household with 2 people
First, calculate the total frequency
[tex]Total = 3 + 4 +6+7+5[/tex]
[tex]Total = 25[/tex]
The frequency of household with 2 people is:
[tex]f(2) = 4[/tex]
So, the percentage is calculated as:
[tex]\% =\frac{f(2)}{Total} * 100\%[/tex]
[tex]\% =\frac{4}{25} * 100\%[/tex]
[tex]\% =\frac{400}{25}\%[/tex]

Answers
Answer:
Total number of arrangements for 5 players = 15,120 arrangements
Step-by-step explanation:
Given:
Number given from 1 to 9
So,
Total number for jerseys = 9
Find:
Total number of arrangements for 5 players
Computation:
Total number of arrangements for 5 players = 9! / [9! - 5!]
Total number of arrangements for 5 players = 9 x 8 x 7 x 6 x 5
Total number of arrangements for 5 players = 15,120 arrangements

Answers
Answer:
Step-by-step explanation:
Gabriela has solved incorrectly. 5 should distributed to 9x & (-8) and 4 should be distributed between x & 2
5(9x - 8) = 4*(x + 2)
5*9x - 5*8 = 4*x + 4*2
45x - 40 = 4x + 8
Subtract 4x from both sides
45x - 4x - 40 = 8
41x - 40 = 8
Add 40 to both sides
41x = 8 + 40
41x = 48
x = 48/41

The combination locks on the lockers at Hillside School have numbers from 0 through 39 (inclusive). A locker combination consists of three different numbers, where the order matters. Because of the way the locks are manufactured, all three numbers are even or all three numbers are odd. How many combinations are possible
Answers
Answer:
13680
Step-by-step explanation:
Since we have number from 0 to 39 inclusive, there are 40 number all together.
Now there are 20 odd numbers and 20 even numbers since half of the the numbers are odd and half even.
Now, since we require 3 numbers for our locker combination which are either all even or all odd, the number of ways we can arrange 3 numbers from 20 when the order matters is ²⁰P₃ = 6480 ways for either odd or even numbers. So, for both odd and even numbers, we have the sum of even and odd number of ways ²⁰P₃ + ²⁰P₃ = 2 × ²⁰P₃ = 2 × 6480 = 13680. So, we have 13680 combinations of locks.

A map has a scale of 2 inches : 25 miles. Chandra uses the map to find the distance from the zoo to her house. The distance on the map is 5 inches. How many miles away is the zoo from Chandra’s house?
Answers
Step-by-step explanation:
Turn the ratio into a fraction
2in /25 mi
You want to have miles so you can flip the fraction and mutiply to cancel out the inches
(25mi / 2in) x 5in = (25 mi x 5in) / 2in
find the time in which a train of length 132 M will cross and electric post if the speed of the train be to 6.4 km /hour
Answers
Answer:
It will take the train 1.2375 minutes to pass the tunnel
Step-by-step explanation:
Mathematically, we know that ;
time = distance/ speed
The distance here is the length of the train which is 132 m ; we can convert this to km by dividing by 1000
We have this as 132/1000 = 0.132 km
So, we have the time as;
0.132 km/6.4 km/hr = 0.020625 hr
Mathematically, we know that 60 minutes make an hour;
so we have
0.020625 * 60 = 1.2375 minutes

the angle of elevation from point A to the top of the press box is 49 digree. if point A is 400ft from the base of press box, how high is the press box?
Answers
Answer:
Press box is 460.15 feet high.
Step-by-step explanation:
From the picture attached,
Point A is 400 feet away from the press box.
Angle of elevation of point C is 49°.
By applying tangent rule in the given right triangle,
tan(49°) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
tan(49°) = [tex]\frac{BC}{AB}[/tex]
BC = ABtan(49°)
BC = 400[tan(49°)]
BC = 460.15 ft
Therefore, press box is 460.15 feet high.

Latoya earns 41 dollars per week working part-time at a book store. She makes one dollar more for each book that she sells. The amount, A (in dollars), that Latoya earns in a week if she sells b books is given by the following.
A=41+b
How much does Latoya earn in a week if she sells 16 books?
Answers
Answer:
57$
Step-by-step explanation:
The equation is A= 41 + b
A represents the entire amount she makes that week.
41 is the minimum she makes every week.
b represents any books she sells which earn an extra 1 dollar.
Plug in 16 books into the equation.
A= 41+ 16
A= 57

Plot the coordinates of the point:
(a) whose co-ordinate is -5 and which lies on y axis.
(b) Which lies on x and y-axis both.
(c) whose abscissa is 3 and which lies on x-axis in cartasian plance.
Answers
Answer:
First, a regular point is written as a coordinate pair (x, y).
If the point lies on the x-axis, then we have y = 0
if the point lies on the y-axis, then x = 0
And x is the abscissa, y is the ordinate.
The points will be graphed at the end.
a)
Ordinate = -5, then y = -5
and it ies on the y-axis, then x = 0
So this point is represented by A = (0, -5)
b)
Lies on the y-axis and in the x-axis, then x = 0 and y = 0, so the point is represented by B = (0, 0)
c)
The abscissa is 3, so x = 3, and the point lies on the x-axis, so y = 0
Then this point is represented by C = (3, 0)

Answers

8^2+x + 2^ 3x = 32^ 1/2
2^3(2+x) + 2^3x = 2^5^1/2
All two's will cancel out
3(2+x) + 3x = 5^1/2
6+3x + 3x = 5^1/2
6 +6x = 2.23
6x = 2.23 - 6
6x = -3.77
x = -3.77÷ 6
