Answer:
D) no solution
Step-by-step explanation:
2x - 4y = 14
X + 2y = 7
2x - 4y + x + 2y = 14 + 7
2x - 4y + x + 2y = 21
3x - 2y = 21
no solution
Answer:
y = 10
Step-by-step explanation:
The opposite sides of a parallelogram are congruent, hence
x + 10 = 110 - 4x ( add 4x to both sides )
5x + 10 = 110 ( subtract 10 from both sides )
5x = 100 ( divide both sides by 5 )
x = 20
Using the other pair of congruent sides, then
3y - 10 = 2x - 20 = (2 × 20) - 20 = 40 - 20 = 20, thus
3y - 10 = 20 ( add 10 to both sides )
3y = 30 ( divide both sides by 3 )
y = 10

Step-by-step explanation:
Hello!
The standard deviation (δ) is a measure of variability, this means, it shows how dispersed the data set is with respect to the mean. The population mean (μ) is a measurement of position. The three graphics have the same position μ=0 but their standard deviations change, this means, the form of their bells is different. The greater the value of the standard deviation, the more dispersed the data is you can see this graphically because the width of the bell will be greater.
Graph attached.
I hope it helps!
Basically, this equation is called the "slope intercept form" and to change into into that, you must simplify the equation.
