Well, you round up if the digit behind the decimal place is 5 or more and round down if the digit is 4 or less
I guess the first is 25.64, since two decimal places means the hundredths, 3. The digit behind is 5 , meaning that 3 will become a 4.
then 315.2
then 0.398
then 15 because the digit behind 9+ is an 8 greater than 5, which means the 9 is rounded up to 10, which is a one when it passes through the decimal point, making it 15.
sorry if my explanation sucks. I hope this helps.
Answer:
12
Step-by-step explanation:
The interquartile range is the difference between the value at the right side of the box and the left side of the box, that is
interquartile range = 85 - 73 = 12
So, Noah would most likely have - wait hold up what's the main question?is it how much Noah has? if it is I will be able to solve it. Or is it how much water will fill it or something?
Answer:
Option C is correct i.e. 2.
Step-by-step explanation:
Given the function is f(x) = x² +8x -2.
We can compare it with general quadratic expression i.e. ax² +bx +c.
Then a = 1, b = 8, c = -2.
We can find the number of real root by finding discriminant of the equation ax² +bx +c =0 as follows:-
D = b² -4ac
D = 8² -4*1*-2
D = 64 +8
D = 72.
When D is a positive value, then we have two real roots of the equation.
Hence, option C is correct i.e. 2.
