There are 100 squares in the grid.
63 are shaded.
Number of squares shaded is the numerator (number on top of the decimal).
Total number of squares is the denominator (number at the bottom of the decimal).
Whenever the denominator of the fraction is 100, you can just take the numerator and put a decimal behind the number.
Therefore, the decimal represented would be 0.63.
Answer:
1. 1/2 +/-√5
2. 1 +/- i √6/2.
Step-by-step explanation:
1. f(x) = 4x^2 - 8x - 1
x = [-(-8) +/-√((-8)^2 - 4*4*-1)] / (2*4)
x =[ 8 +/- √80] / 8
= 1 +/- 4√5/8
= 1 +/- √5/2
= 1/2 +/-√5
2. By a similar method the zeros of the the second equation are:
x = [-(-4) +/- √((-4)^2 - 4*2*5)] / 4
= 4 +/- √(16 - 40) / 4
= 1 +/- √(-24)/4
= 1 +/- i √6 * 2 / 4
= 1 +/- i √6/2.
Answer:18
Step-by-step explanation:
Just count the square
Answer:
The median is 37
Step-by-step explanation:
The median is the middle number in the set when organizaed from low to high:
15, 22, 37, 49, 82
From this arrangement, we can see that 37 is the middle number making it the median.
