Part 2 is 12.5 cm represents 5km
I worked this out by doing a ratio
5cm=2km
?cm=5km
you have to do 2 times 2.5 to get 5km so you do 5 times 2.5 to get 12.5cm
so the answer is that 12.5cm

What is the Median for the following set of numbers? â€‹21 23 76 47 55 135 45 30 17

Leno4ka [110]

Answer:

Median = 45

Step-by-step explanation:

We are given the following data set:

21, 23, 76, 47, 55, 135, 45, 30, 17

Median is the number that divides the data into two equal parts.

Formula:

$Median:\\\text{If n is odd, then}\\\\Median = \displaystyle\frac{n+1}{2}th ~term \\\\\text{If n is even, then}\\\\Median = \displaystyle\frac{\frac{n}{2}th~term + (\frac{n}{2}+1)th~term}{2}$

Sorted data:

17, 21, 23, 30, 45, 47, 55, 76, 135

Sample size = 9, which is odd

Median =

$\dfrac{9+1}{2}^{th}\text{ term} = \dfrac{10}{2}^{th}\text{ term} = 5^{th}\text{ term}\\\\= 45$

The median of given set of numbers is 45.

Rich and Aylen are saving money to buy baseball tickets. Rich has $5 more than 3 times the amount of money Aylen has. Together,

Olenka [21]

Answer:

4x + 5 = 101

Step-by-step explanation:

<u>Step 1: Determine how much money both have</u>

Aylen: x

Rich: 5 + 3x

<u>Step 2: Write an equation and solve</u>

Aylen + Rich = 101

x + 5 + 3x = 101

<u>Step 3: Solve the equation</u>

x + 5 + 3x = 101

4x = 96

x = 24

Step 4: Determine how much money does Aylan and Rich have

Aylan has $24

Rich has 5 + 3(24) = $77

If one three-digit number ( 0 cannot be a left digit) is chosen at random from all those that can be made from the following set

Oksana_A [137]

The probability of choosing a number that is not a multiple of 2 is P = 0.44

<h3 /><h3>How to find the probability?</h3>

We need to count the number of options for each digit.

For the first digit, we have 8 options {1, 2, 3, 4, 5, 6, 7, 8}
For the second digit, we have 9 options {0 ,1, 2, 3, 4, 5, 6, 7, 8}
For the third digit, we have 9 options {0 ,1, 2, 3, 4, 5, 6, 7, 8}.

The total number of combinations is the product between the numbers of options:

C = 8*9*9 = 648

If we want our number to not be a multiple of 2 then it must end in a odd digit, the combinations that meet that condition are:

For the first digit, we have 8 options {1, 2, 3, 4, 5, 6, 7, 8}
For the second digit, we have 9 options {0 ,1, 2, 3, 4, 5, 6, 7, 8}
For the third digit, we have 4 options {1, 3, 5, 7}.

C = 8*9*4 = 288

Then the probability of selecting a 3 digit number that is not a multiple of 2 is:

P = 288/648 = 0.44
