Answer:

Step-by-step explanation:

SST = ∑ ( y − ȳ ) ² (ȳ = pronounced y bar is the mean of y values)

ȳ = (5+8+14)/3 = 27/3 = 9

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

= ( − 4 ) ² + ( - 1 ) ² + ( 5 ) ²

= 16 + 1 + 25

Kiera and Trina joined a gym. The gym offers two different payment plans. Kiera chose Plan 1 and pays $25 a month and no fee to

Lady_Fox [76]

Answer:

t1 = $25m

t2 = $(10m + 100)

Step-by-step explanation:

Here we want to write equations

Kiera chose plan 1

$25 monthly and no joining fee

So the amount after m months will be 25 * m

t1 = $25m

Trina chose plan 2

$10 a month and $100 joining fee

after m months , total payment will be

10(m) + 100 = $(10m + 100)

Thus t1 = $25m and t2 = $(10m + 100)
