Answer:
the reasoning states that "all the numbers begin with a 7 or an 8"
however this is not accurate as they can be in different placements
which can make a big difference in the total estimate.
for example:
the number could've been an 8, or an 80
they both begin with an 8
however have totally different values and could have messed up the total estimated number.
hope this helps :D
Answer:
$18
Step-by-step explanation:
Because 25% is 1/4 of of a whole, 72/4 is 18. You can also put it into a calculator
Answer:
17.74
Step-by-step explanation:
To write a fraction as a decimal, one of the easiest ways to do so is to turn the denominator into 100. The whole number will stay the same if the numerator is less than the denominator. So in this case, 17 stays the same. To change 37/50 to a fraction with a denominator of 100, multiply by 1 (1/1, 2/2, etc). In this case, we multiply by 2/2. This means 37/50 is equivalent to 74/100. 74 over 100 is 0.74, since 74 out of 100 is 74%. Then to convert a percent to decimal, move the decimal place two places to the left. 74.00 two decimal places to the left is 0.74. Then add the whole number 17. 17 + 0.74 is equal to 17.74.
Answer: i believe it's the slope of AB is different than the slope of BC
You can see that there is a proportional relationship between X and Y because every 6 of X decreases 3 in Y. In that way you can say is a linear relationship and you can construct a linear equation: Now, to calculate the equation you use: (Y - y1) = y2 - y1 (X - x1) x2 - x1 Let's peek two pairs (1,-4) and (7,-7) (Y - (-4)) = (-7 - (-4)) (X - 1) (7 - 1) <span>Y + 4 = -3 (X - 1)</span> 6 If you want to express the equation as aX + bY + C = 0 Y + 1/2 X + 7/2 = 0 If you want to express the equation as Y= ax + b <span>Y = -1/2X - 7/2</span>
