D. y=-3/10x+1/2
Step-by-step explanation:
Using rise/run you can count the units the line moves from one point to another, from the left point to the right point the line travels down 3 and over 10 so you get -3 as your rise (it is negative because the line is traveling downwards) and 10 as your run, so your slop is -3/10. By looking at the graph you can see that your y-intercept is 1/2. SO when plugged into y=mx+b with m as -3/10 and b as 1/2 you get the equation y=-3/10x+1/2, or letter D.
First turns those into fractions, now you should have 4/5 and 1/5.
Now to generate a chance the 2 events will happen in a row (Like rain and a postponed game) you need to multiply the 2 fractions together so it should come out with 4/25 or 16%
The correct equation of 146 ÷ 7 = 20857 is 146.0 ÷ 7.0 = 20.857
<h3>How to divide the decimals?</h3>
The equation is given as:
146 ÷ 7 = 20857
The above equation is wrong.
The equation can be rewritten as:
146.0 ÷ 7.0 = 20857
The significant digits in 146.0 and 7.0 are 3 and 1, respectively.
3 - 1 = 2
This means that
So, the decimal place in the result must be after the second digit.
So, we have:
146.0 ÷ 7.0 = 20.857
Using the above highlights, we have:
146 ÷ 0.7 = 208.57
1.46 ÷ 7 = 0.20857
14.6 ÷ 0.7 = 20.857
1460 ÷ 70 = 20.857
The reasoning behind the above equations is that the decimal position in the results is dependent on the decimal positions in the dividend and divisor
