What is the sST for the data set (1, 5), (2, 8), (4, 14)? 14 42 25 9

ohaa [14]

Answer:

Step-by-step explanation:

SST = ∑ ( y − ¯ y ) ² (¯ y = mean of y values)

¯ y = (5+8+14)/3 = 27/3 = 9

∑ ( y − ¯ y ) ² = ( 5 − 9 ) ² + ( 8 − 9 ) ² + ( 14 −9 ) ²

= ( − 4 ) ² + ( − 1 ) ² + ( 5 ) ²

= 16 + 1 + 25

= 42

If m and n can be any integers such that n<4 and 4m - 3n < 20, which of following is the solution set for m?A m <7.25B

soldier1979 [14.2K]

If we multiply the inequality n<4 by 3 we get the following:

$(n$

Now, on the next inequality we have the following:

$\begin{gathered} 4m-3n$

By transitive property, we have:

$\begin{gathered} 3n$

therefore, the solution set for m is m<8

What’s the value of x? :/

kolbaska11 [484]

Answer:

$x = 27$

Step-by-step explanation:

According to congruent chords and arcs theorem, if $\overline{XY} \cong \overline{ZY}$ then $\arc{XY} \cong \arc{ZY}$ .

This means that $\arc{XY} = \arc{ZY} = (6x - 20) degrees$

Thus:

$\arc{XY} + \arc{ZY} + \arc{ZX} = 360$ (full circle = 360°)

$\arc{XY} = (6x - 20)$

$\arc{ZY} = (6x - 20)$

$\arc{ZX} = 76$

Plug in the values into the equation

$(6x - 20) + (6x - 20) + 76 = 360$

$6x - 20 + 6x - 20 + 76 = 360$

Add like terms

$12x + 36 = 360$

Subtract 36 on both sides

$12x = 360 - 36$

$12x = 324$

Divide both sides by 12

$x = 27$
