Distribute on the left
3x+1=3x+1
Since the equations are equivalent, x can be any number and the equation will be true.
Final answer: Infinitely many solutions
We just multiply the scale factor times the original length of the square:
3.5(2.8) = 9.8
9.8 is the length of the enlarged picture
Circumference of Circle = 2πrArea of circle = πr²144 = 3.14 * r²r² = 144/3.14r² = 45.85r = √45.85r = 6.77 Circumference = 2πr = 2*3.14*6.77Circumference = 42.51 m²
So, your answer is 42.51 m²
The population size of the above data is 8, that is N=8
The mean (average) = (<span>12 +10+ 11.5 +11.5 +12 +9 +9 +11)/8
= 10.75
Standard deviation is the square root of variance, it is one of the measures of central dispersion, that is a measure of by how much the values in the data set are likely to differ from the mean.
In this case, Standard deviation, </span>s= √(∑(x-m)²)/(n-1)
= 1.172
Thus, best approximation of the standard deviation is 1.17
Ok so change the questions to -5y=10-2x then divide both side 5y=-10+2x then record the terms y=-2+2/5x the answer is y=2/5x-2
