Question:
Jin Ya take the bus across town to school each morning last week he timed his trips and found that the time varies day today the time in minutes or listed below:
10 15 11 13 11
If you had to use one number to tell someone how long it took Jin Ya to get to school, what would you say?
Answer:
11 minutes or 12 minutes
Step-by-step explanation:
Given:
10 15 11 13 11
Required
Determine one number that summarizes the 5 numbers
First, one can use the mean to get the summary of the numbers.
The mean is calculated as:
[tex]Mean = \frac{Sum\ of\ observation}{Number\ of\ observation}[/tex]
[tex]Mean = \frac{10 + 15 + 11 + 13 + 11}{5}[/tex]
[tex]Mean = \frac{60}{5}[/tex]
[tex]Mean = 12[/tex]
Another number that summarizes the numbers is the mode of the distribution.
[tex]Mode = Highest\ Occurring\ Value[/tex]
So, in this case:
[tex]Mode = 11[/tex]
Hence, you can either use 11 minutes or 12 minutes.

-5(t + 3)= -30
Solve for the variable!! Please
Answer:
[tex]\huge\boxed{t=3}[/tex]
Step-by-step explanation:
[tex]-5(t+3)=-30[/tex]
METHOD 1:[tex]-5(t+3)=-30[/tex] divide both sides by (-5)
[tex]\dfrac{-5\!\!\!\!\diagup(t+3)}{-5\!\!\!\!\diagup}=\dfrac{-30}{-5}[/tex]
[tex]t+3=6[/tex] subtract 3 from both sides
[tex]t+3-3=6-3\\t=3[/tex]
METHOD 2:[tex]-5(t+3)=-30[/tex] use the distributive property a(b + c) = ab + ac
[tex](-5)(t)+(-5)(3)=-30[/tex]
[tex]-5t-15=-30[/tex] add 15 to both sides
[tex]-5t-15+15=-30+15[/tex]
[tex]-5t=-15[/tex] divide both sides by (-5)
[tex]\dfrac{-5t}{-5}=\dfrac{-15}{-5}\\\\t=3[/tex]

If the perimeter of this triangle is 15 centimeters, what is the value of n?
5n - 6
n
2n + 1
Express your answer as a decimal number.
Answer:
25/14
Step-by-step explanation:
The value of n that makes up the triangle of perimeter 15 centimeters is 2.5
How to determine the value of n?The side lengths of the triangle are given as:
5n - 6, n and 2n + 1
The perimeter is given as:
P = 15
The perimeter is the sum of the side lengths.
So, we have:
5n - 6 + n + 2n + 1 = 15
Collect like terms
5n + n + 2n = 15 + 6 - 1
Evaluate the like terms
8n = 20
Divide both sides by 8
n = 2.5
Hence, the value of n that makes up the triangle is 2.5

a bus travels 320 miles in 6.4 hours. if the bus continues at the same rate, which proportion can be used to find m, the number of miles the bus will travel in 9 hours.
Answer:
A
Step-by-step explanation:
Ok first we need to find rate of MILES per HOUR
320/6.4=50
m= miles in 9 hours
9*50=450
Cross Multiplyis your answer
A
(6.4*9)/320m=Hours/miles
Hope this helps!
The number of miles the bus will travel in 9 hours will be 6.4 / 320 = 9 / m. Then the correct option is B.
What are ratio and proportion?A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.
A bus travels 320 miles in 6.4 hours. if the bus continues at the same rate.
We know that speed is the ratio of distance and time. Then we have
The number of miles the bus will travel in 9 hours will be
320 / 6.4 = m / 9
6.4 / 320 = 9 / m
Then the correct option is B.

2x+3y=4 y+3x=6
find x and y
Answer:
x=-3/2y+2
y= y=−3x+6
Step-by-step explanation:
solve for x.
2x+3y=4
Add -3y to both sides.
2x+3y+−3y=4+−3y
2x=−3y+4
Divide both sides by 2.
2x/2= -3+4/2
x= -3/2 y+2
solve for y.
y+3x=6
Add -3x to both sides.
3x+y+−3x=6+−3x
y=−3x+6
How can you write the equation for a linear function if you know only two ordered pairs for the function? Drag tiles tho complete the explanation. Tiles may be used once, more than once, or not at all.
Answer:
Explanation below
Step-by-step explanation:
First determine the slope using (y2-y1)/(x2-x1)
Then set up point slope form and add in an ordered pair for x and y to determine the y intercept: y - y1 = m(x - x1). Solve for y and you'll end up with slope intercept form.
For example: (-2,1), (3,2) find slope and y intercept.
(2-1)/(3-(-2))= 1/5
y-2=.2(x-3)
y=.2x-.6+2
y=.2x+1.4 or y=(x/5)+(7/5)

The mean length of 11 adults' big finger is 14.1cm.
What is the mean length (rounded to 2 DP) of these 21 people's big finger?
Answer:
The mean length of 10 children's big finger is 8.1 cmAverage length of all the 10 children's finger is (8.1×10) cm = 81 cm.
The mean length of 11 adult's big finger is 14.1 cmAverage length of all the 11 adult's big finger is (14.1×11) cm =155.1
