Or, Final value = $550 ( 1 +\frac{10.12}{100})^{3}

Or, Final value = $550 (1.102)³

Or, Final value = $550 × 1335

I.e final value = $734.44

Polynomial Factorization Help!
aleksklad [387]
Since there is a 2 at the start, we actually multiply -5 by 2, meaning that it needs to multiply to (-5*2)=-10 and add up to -3. Since -5 and 2 fit the bill, we get (x+5)(x-2)=0 (as -5+5 and 2-2=0)

In an area of Russia records were kept on the relationship between the rainfall (in inches) and the yield of wheat (bushels per
skelet666 [1.2K]

Answer:

Option d.

Step-by-step explanation:

The equation of the line of least squares is given as

\hat{y} = -9.12+ 4.38x

where \hat{y} is the yield of wheat (bushels per acre) and x is the rainfall (in inches).

We need to find the expected number of inches of rain if the yield is 60 bushels of wheat per acre.

Substitute \hat{y}=60 in the given equation.

60= -9.12+ 4.38x

Add 9.12 on both sides.

60+9.12=4.38x

69.12=4.38x

Divide both sides by 4.38.

\frac{69.12}{4.38}=x

x\approx 15.78

The expected number of inches of rain is 15.78.

Therefore, the correct option is d.
