Answer:370mm^3
Step-by-step explanation:
You would first find the area of the whole rectangle without the hole, so (15)(30)=450
Next find the area of the hole, (8)(10)=80
To find the area you must subtract the area of the hole from the rectangle.
450-80=370
Answer: 9 points
Step-by-step explanation:
The coefficient of determination is a number between 0 and 1 used to measure the level of precision with which the regression model created fits the data. A measure of means that the model explains the entire variation between the two variables without error.
Therefore, in this case if means that the 9 points are on the line
Answer:
To make a table<em> NOT</em> a function you can make any input value lead to two or more outputs.
Step-by-step explanation:
Ex.
(2,3)
(1,4)
(6,7)
(2,8)
1. Put the numbers in order from smallest to largest, e.g. 2, 6, 12, 18, etc.
Range:
To work out the range take the biggest number and the smallest number and subtract them from each other… e.g. 18-2=16 so the range is 16
Mean:
Add all the numbers together and divide by how many of them there is, e.g. 2+6+12+18=38/4=9.5 so the mean is 9.5
Median:
Again make sure the numbers are in order from smallest to biggest, start crossing out the first number then the last number then the second then the second to last until you get the middle number, e.g.-2-, 6, 12, -18- …. Since I have two numbers in the middle to find the median you have to find the number in between them, if it’s easy to spot like 5, 6 would be 5.5 you can just find it by looking but if there’s a large difference like the 6, 12 in my made up sequence just add the 2 number together and divide by 2 e.g. 6+12=18/2= 9 so the median is 9
(If there’s only one number it’s just that one number)
Mode:
Mode is the number that occurs the most, for example 2, 6, 12, 18 hasn’t got a mode but if it was 2, 6, 6, 12, 12, 12, 18
The mode would be 12 because there’s the most of it, 3 while only two 6s, one 2 and one 18.
Hope this helps! I would’ve done the answers for you but I couldn’t see the whole sequence. Good luck! :)
The answer is the first and second answers. This is because when you deal with ratios you can get an equal ratio by multiplying both sides of the ratio by the same number. In the first answer both side of the ratio were multiplied by 2. 4 x 2 = 8 and 1 x 2 = 2.
