Mathematics
1 answer:
mina [271]2 years ago

Step-by-step explanation:

The question asks for you to talk about precision and accuracy, precision is defined by how close the results are when repeated so the three results are precise. The difference in weight between the three measurements is within .3g of each other so this proves your precision is good.

However, the accuracy is bad because the results and the actual weight of the apple are far away, the mean distance can be calculated via adding up all three measurements and dividing by three:

167 + 166.9 + 167.2 = 501.1

501.1 ÷ 3 = 167.03

172 - 167.03 = 4.97

So the mean distance is 4.97g away from the actual weight of the apple, this shows that the results are not accurate.

Hope this helps!

Caroline is making some table decorations.
eduard

Answer:

there are 8 candles

Step-by-step explanation:

(i) In order to obtain an equal amount of candle to candle holders Caroline has to buy enough packs to obtain a 1:1 ratio.  

Therefore to obtain a 1:1 ratio:

=30 candles/18 candle holders * (18/30)

Therefore she needs to buy 18 packs of candles and 30 packs of candle holders to have exactly the same number of candles and holders

(ii) Caroline can make = 30*18 = 540 table decorations

pen costs twice as much as a pencil. The total cost of 1 1 pen and 1 1 pencil is $2.10 $ 2 . 10 . If p represents the cost of 1
dybincka [34]

Answer : The equation could you use to find p is, 2p+p=2.10

Step-by-step explanation :

Let the cost of 1 pen be, 'x'

and the cost of 1 pencil is, 'p'

As we are given that total cost of 1 pen and 1 pencil is $2.10. The equation will be:

x+p=2.10    ............(1)

And we have also given that the pen costs twice as much as a pencil. The equation will be:

x=2p    ............(2)

Now put the equation 2 in equation 1, we get:

x+p=2.10

2p+p=2.10

Thus, the equation could you use to find p is, 2p+p=2.10

Given the following system, what would be the best way to start slowing the system?
dusya [7]
A would be the correct answer because the y variable only has a coefficient of 1. So we would solve for y, which would get us y=3x+5, then we would substitute the value in the second equation which would look like -4x+5(3x+5)=58. Hope this helpss. :)
