Well u could make a tree with the 2 numbers on top so one of the numbers on one tree and the other number on the other and then make a triangle so if the 2 numbers are 12 and 8 then you would put 8 on one and 12 on the other and then put a triangle under the 2 numbers and then lis the 2 numbers that multiply to get those answers so for 8 it would be 2 and 4 you would circle the 2 because it has nothing that can be multiplied to get it and keep going with 4 and get 2 and 2 and then circle the 2s then make a table and put the 2 2s in one column and then put the other 2 in another column then bring one number down from each column and multiply them together and you will get your answer if there are all different numbers then put them in all separate columns. Hope this helped!

The table below shows the lowest temperature, in degrees fahrenheit, on each of 5 days. What is is mean lowest temperature, in d

Yuki888 [10]

Answer: -7

Step-by-step explanation:

To calculate mean , the formula is given by:-

$Mean=\frac{\text{Sum of all observations }}{\text{Number of all observations}}$

From the given values of temperature in the table.

The sum of temperature in degrees Fahrenheit, in the city for those 5 days is given by $S=-36+(-25)+12+(-4)+18=-36-25+12-4+18\\\Rightarrow\ S=-35$

The number of days N = 5

So the mean lowest temperature, in degrees fahrenheit, in the city for those 5 days is given by:-

$Mean=\frac{S}{N}=\frac{-35}{5}=-7$

Calculate the volume, in cubic centimeters, of a box which is 125 cm long, 37 cm wide, and 68 cm high. Report your answer with c

viva [34]

Answer:

$Volume = 314500cm^3$

Step-by-step explanation:

Given

$Length = 125cm$

$Width = 37cm$

$Height = 68cm$

Required

Determine the volume

Volume is calculated as:

$Volume = Length * Width * Height$

Substitute values for Length, Width and Height

$Volume = 125cm * 37cm * 68cm$

$Volume = 314500cm^3$

<em>Hence, the volume of the box is </em> $314500cm^3$ <em></em>

I got zero, but that’s wrong.

Answer:

Expected value is 4,000

Step-by-step explanation:

To find expected value ⇒ multiply the value by it's probability

40% × ( -25,000 ) = - 10,000

Breaking means neither add nor subtract a given amount

20% × 0 = 0

35% × 40,000 = 14,000

∴ Expected value = -10,000 + 14,000 = 4,000

LOSS: -10,000

BREAK EVEN: 0

WIN: 14,000

Expected value is 4,000
