Answer: Rational number
It is a rational number because it is a fraction of two integers. Those two integers being -15 and 2.
In general, any rational number is of the form P/Q where P and Q are integers. The Q cannot be zero. Another example of a rational number is 2/3. In this example, P = 2 and Q = 3.
Going back to -15/2, we would have P = -15 and Q = 2.
The fraction -15/2 is not a whole number nor is it an integer. This is because -15/2 = -7.5 and this is sufficient to see we don't have an integer result. We would need to have nothing after the decimal point to get a whole number.
Answer:
You have to compare if true some of the statements.
Most of these type questions would be compare the first three data
1. Prices of red to yellow mean we need to add them all up to begin with. 10 x £29.95 + 5 x 35.99 etc. = 15 items or add one zero (x10) to 29.95 and for 35.99 we add zero (x10) then divide by 2 ie) 359.9/2 = 360/2-0.2 = 180 - 0.2 = $179.98
2. Higher and lower comparisments we just take away from total.
3. The difference or how much more something is we subtract from the full total.
This would be a 4 way thought process below;
1. Prices in $ could mean groups, mean high or low we need to count how many items and add up all the prices to find the mean by adding them together.
2. Colour's could mean more red than yellow over a certain price or under a certain price.
3. Colour could also mean how many as a combined data were higher or lower than a certain price. ie) Higher than $29.99 would mean all the data set at $30.00 more. LEss would mean lower than $29.98
4. Mean and fx would be all the prices added together + all the items togather for the fx we multiply the individual groups and create a new box. We then multiple it to the other totals. This can also help establish or be compared to the percentage for advanced data tables.
Step-by-step explanation:
Answer:
-6.1 - (-3.13) = -2.97
1) We calculate the volume of a metal bar (without the hole).
volume=area of hexagon x length
area of hexagon=(3√3 Side²)/2=(3√3(60 cm)²) / 2=9353.07 cm²
9353.07 cm²=9353.07 cm²(1 m² / 10000 cm²)=0.935 m²
Volume=(0.935 m²)(2 m)=1.871 m³
2) we calculate the volume of the parallelepiped
Volume of a parallelepiped= area of the section x length
area of the section=side²=(40 cm)²=1600 cm²
1600 cm²=(1600 cm²)(1 m² / 10000 cm²=0.16 m²
Volume of a parallelepiped=(0.16 m²)(2 m)=0.32 m³
3) we calculate the volume of a metal hollow bar:
volume of a metal hollow bar=volume of a metal bar - volume of a parallelepiped
Volume of a metal hollow bar=1.871 m³ - 0.32 m³=1.551 m³
4) we calculate the mass of the metal bar
density=mass/ volume ⇒ mass=density *volume
Data:
density=8.10³ kg/m³
volume=1.551 m³
mass=(8x10³ Kg/m³ )12. * (1.551 m³)=12.408x10³ Kg
answer: The mas of the metal bar is 12.408x10³ kg or 12408 kg
