The first step in solving 3.17 t - 2.431 = 5.06 is to divide both sides of the equation by 3.17. TrueFalse

Pavlova-9 [17]

Answer:

False

Step-by-step explanation:

$3.17t - 2.431 = 5.06 \\ 3.17t = 5.06 + 2.431 \\ 3.17t = 7.491 \\ \frac{3.17t}{3.17} = \frac{7.491}{3.17} \\ t = 2.363$

In the number 8.028 does one 8 have a value of 100 times the other 8 ?

nirvana33 [79]

Answer:

No, The 8 in the ones place of the decimal and the 8 in the thousands. Decimals go by variables of 10 if that makes sense

so hopping from the 8 in the ones place it would go 10, 100,1000.

Therefore the statement is false because the value between the eitghts is not 100 its 1000

Answer:

1/7

Step-by-step explanation:

The slope formula is useful for this.

m = (y2 -y1)/(x2 -x1)

m = (4 -3)/(4 -(-3)) = 1/7

The gradient of the line segment is 1/7.

Answer:

The resulting residual value is e=-40.24.

Step-by-step explanation:

The residual value e for a regression model is defined as the difference between the real value y and the predicted value yp:

$e=y-y_p$

The predicted value for DISTANCE=0.43 miles is:

$RENT = 1200.4326 - 256.2567\cdot DISTANCE\\\\RENT(0.43) = 1200.4326 - 256.2567\cdot 0.43\\\\RENT(0.43) = 1200.4326 - 110.1904=1090.2422\\\\$

Then, if the real value is $1,050, the residual value is calculated as:

$e=y-y_p\\\\e=1050-1090.2422=-40.2422$
