Answer:

9x

Step-by-step explanation:

EF = 3x. FG is  three times as long  as EF.

3 times as long as EF means we need to multiply EF by 3

FG= 3 times EF

FG= 3 \cdot EF

Now replace EF by 3x

FG= 3 \cdot EF

FG= 3 \cdot 3x

FG= 9x

So FG is 9x

FG = 9x

3x + 9x = 72

12x = 72

x = 6

adoni [48]
8500 you make two fractions set equal to eachother.. 6290/x (x is the missing number) and 74/100 (the percentage) you cross multiply the 6290 and 100 which is 629000 and divide it by the 74 which is 8500 which should be your answer

Given that the sum of squares for error is 60 and the sum of squares for regression is 140, then the coefficient of determinatio
Anastasy [175]

Answer:

<h2>0.7</h2>

Step-by-step explanation:

The coefficient of determination which is also known as the R² value is expressed as shown;

R^{2} = \frac{sum\ of \ squares \ of \  regression}{sum\ of \ squares \ of total}

Sum of square of total (SST)= sum of square of error (SSE )+ sum of square of regression (SSR)

Given SSE = 60 and SSR = 140

SST = 60 + 140

SST = 200

Since R² = SSR/SST

R² = 140/200

R² = 0.7

Hence, the coefficient of determination is 0.7. Note that the coefficient of determination always lies between 0 and 1.

Find the vertex of the parabola whose equation is y = -2x2 + 8x - 5.
miss Akunina [59]
Hello :
<span>y = -2x² + 8x - 5 = -2(x²-4x-5)
but : </span>x²-4x = (x²-4x +2²)-2²
                 = (x-2)² -4
y = -2 ((x-2)²-9)
y = -2 (x-2)²+18
the vertex is A(2,18)
