For making a scatter plot of the data set, which would be the best scale and interval for the axis that represents the amount of fluoride? Water (L) 0.5 08 2 1.5 0.5 25
Fluoride (mg) 0.4 0.4 0.6 1.6 0.8 0.2 1.8

0 to 5 with intervals of 0.1
1 to 2.5 with intervals of 0.5
0 to 2 with intervals of 0.2
1 to 3 with intervals of 1

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.

step-by-step explanation:

so, converting firstly the mixed fractions to improper fractions and then "adding".

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
