Find the median of the data in the box plot below.
cm
Amount of rain in Vietnam cities
(centimeters)
++
4 5 6 7 8 9 10
0 1 2 3
Answer:
The median is 5cm.
Step-by-step explanation:
Median is one of the 3 famous measures of central tendency.
The others are: mean & mode.
A median is the middle figure in an array of figures which are lined up from lowest value to highest value.
Here, the variable we're working with is Amount of rainfall in Vietnam cities (in centimeters).
The data shows 4cm, 5cm, 6cm, 7cm, 8cm, 9cm, 10cm, 0cm, 1cm, 2cm, 3cm
We start by arranging them in order of value; from lowest to highest:
0cm, 1cm, 2cm, 3cm, 4cm, 5cm, 6cm, 7cm, 8cm, 9cm, 10cm
There are 11 values in total.
Since 11 is an odd number, it is easy to find the median in this set of values.
Five values to the left and five values to the right; the median is 5cm!

If a number is odd, then it has a remainder of 1 when divided by 2.
Which is the conclusion of the conditional
Answer:
A number is odd
Step-by-step explanation:
Odd numbers are not completely divisible by 2.
What is the importance of knowing divisibility rules?The importance of knowing divisibility rules is that we can determine whether a number is divisible by certain numbers generally from 1 to 20 or not without actually dividing.
A number is divisible by 2 if it's unit digit is divisible by 2.
A number is divisible by 3 if the sum of the digits is divisible by 3.
A number is divisible by 4 if the last two digits is divisible by 4.
A number is divisible by 5 if its unit digit is 5 or 0.
A number is divisible by 9 if the sum of the digits is divisible by 9.
A number is divisible by 10 if its unit digit is 0.
Given, If a number is odd, then it has a remainder of 1 when divided by 2.
So the numbers which are not completely divisible by 2 have a remainder and are odd numbers and numbers which are completely divisible by 2 with no remainder are even numbers.

Answer:
The dog can eat 2/3 of a bag of food in 1 week
Step-by-step explanation:
If the dog can eat 1/3 of a bag of food in 1/2 week (half of a week), and you're trying to figure out how much the dog can eat in 2/2 (which is equal to 1 week because 2/2 is one whole)

Step 1: Define
2(k - 5) + 3k = k + 6
Step 2: Solve for k
Distribute 2: 2k - 10 + 3k = k + 6Combine like terms: 5k - 10 = k + 6Subtract k on both sides: 4k - 10 = 6Add 10 on both sides: 4k = 16Divide 4 on both sides: k = 4Step 3: Check
Plug in k into the original equation to verify it's a solution.
Substitute in k: 2(4 - 5) + 3(4) = 4 + 6(Parenthesis) Subtract: 2(-1) + 3(4) = 4 + 6Multiply: -2 + 12 = 4 + 6Add: 10 = 10Here we see that 10 does indeed equal 10.
∴ k = 4 is the solution to the equation.

1/4x=-5/6
Answer:
x = -24/5
Step-by-step explanation:
1/4x=-5/6
as 4 is multiplied to x on the left hand side, if we shift 1/4 to the right hand side the equation becomes:
6/-5=4x
now the 4 multiplied to x moves to the left hand side:
(6/-5)x4 =x
x = -24/5

a motorcycle travels 6 mph faster than a sport car. if the sports car can only go 90 miles in the same time that the motorcycle can go 99 miles, find speed of the motorcycle
the speed of the motorcycle is ...... miles per hour
Answer:
The speed of the motorcycle is 66 miles per hour.
Step-by-step explanation:
We use the following relation to build a system of equations.
[tex]v = \frac{d}{t}[/tex]
In which v is the velocity, d is the distance, and t is the time.
Car:
[tex]v_{c} = \frac{d_{c}}{t}[/tex]
We have that the car travels 90 miles, so [tex]d_c = 90[/tex]
Then
[tex]v_{c} = \frac{90}{t}[/tex]
[tex]t = \frac{90}{v_{c}}[/tex]
a motorcycle travels 6 mph faster than a sport car.
This means that [tex]v_m = 6 + v_{c}[/tex], so [tex]v_{c} = v_m - 6[/tex]
Travels 99 miles, so [tex]d_m = 99[/tex]
[tex]v_{m} = \frac{99}{t}[/tex]
Since [tex]t = \frac{90}{v_{c}}[/tex] and [tex]v_{c} = v_m - 6[/tex], we have that [tex]t = \frac{90}{v_{m} - 6}[/tex]
So
[tex]v_{c} = \frac{99}{t}[/tex]
[tex]v_{m} = \frac{99}{\frac{90}{v_{m} - 6}}[/tex]
[tex]v_m = \frac{99(v_{m} - 6)}{90}[/tex]
[tex]99(v_{m} - 6) = 90v_m[/tex]
[tex]99v_m - 594 = 90v_m[/tex]
[tex]9v_m = 594[/tex]
[tex]v_m = \frac{594}{9}[/tex]
[tex]v_m = 66[/tex]
The speed of the motorcycle is 66 miles per hour.
how long does it take for a parachute to hit the ground from one meter
Answer:
Your first few seconds in freefall will be a wee bit slower, so you'll cover a little less distance at first, but then you'll accelerate to full speed. The first 300 or so meters (1,000 feet) will take about 10 seconds to fly through. Then 5 seconds for every 300 meters after that.

the actual distance between two cities is 135 km. The map scale is 1cm: 100 km. Find the map distance.
someone pls helpp !!!
Answer:
1.35cm
Step-by-step explanation:
Given the scale of the map
1cm = 100km
For 135km;
x cm = 135 km
Divide both equations
1/x = 100/135
100x = 135
x = 135/100
x = 1.35cm
Hence the map distance will be 1.35cm
A function is shown: f(x) = (1.07)x What does the function represent? Exponential growth of 7% Exponential decay of 7% Exponential growth of 93% Exponential decay of 93%
Answer:
Exponential growth of 7%
Step-by-step explanation:
We are given the function:
A function is shown: f(x) = (1.07)^x
We can compare this to a formula of Exponential Growth
y = a(1 + r)^x
Hence:
1 + r = 1.07
r = 1.07 - 1
r = 0.07
Converting to percy
0.07 × 100
= 7%
Therefore, the function represents Exponential growth of 7%
Answer:
It is
Exponential decay of 93%

You invested $12,000 and earned 7.5% interest, which was compunded continuously. If you had $23,568.40 at the end of the investment, how
long was the investment for?
Answer:
9 years
Step-by-step explanation:
Formula for continuous compounding is;
Total amount after the compounding period = P + P[(e^(rt)) - 1]
Where;
P = principal
r is interest rate
t is time period of compounding
We are given;
P = $12,000
Interest rate; r = 7.5% = 0.075
Time; t =?
Amount after investment; $23,568.40
Thus;
23568.40 = 12000(1 + [(e^(0.075t)) - 1])
(1 + [(e^(0.075t)) - 1]) = 23568.40/12000
[(e^(0.075t)) - 1] = (23568.40/12000) - 1
[(e^(0.075t)) - 1] = 0.964
(e^(0.075t)) = 1 + 0.964
(e^(0.075t)) = 1.964
0.075t = In 1.964
0.075t = 0.67498
t = 0.67498/0.075
t = 9 years
