priya finds (1.05) x (2.8) by calculating 105 x 28 then moving the decimal point three spaces to the left

Answers

Answer 1

Answer:

Yes, That is correct.

Step-by-step explanation:

Example: Multiply 0.05 by 1.1

start with:

 0.05 × 1.1

multiply without decimal points:

 5 × 11 = 55

0.05 has 2 decimal places,

and 1.1 has 1 decimal place,

so the answer has 3 decimal places:

 0.055

Answer 2

Priya's method easy finds the product of decimals because multiplying whole numbers is easier than multiplying decimal numbers.

Given that, Priya finds (1.05) × (2.8) by calculating 105 × 28 and then moving the decimal point three spaces to the left.

We need to explain why Priya's method makes sense.

How to multiply two decimals?

To multiply decimals, first, multiply as if there is no decimal. Next, count the number of digits after the decimal in each factor. Finally, put the same number of digits behind the decimal in the product.

Now, 105 × 28 = 2,940

Moving the decimal point three spaces to the left, we get 2.940.

Also, (1.05) × (2.8) =2.940

Therefore, Priya's method easy finds the product of decimals, because multiplying whole numbers is easier than multiplying decimal numbers.

If the linear model applies the function f(x) = 1.3x + 9.2, what is the predicted value and residual
when the tree is 3 years old with a height of 14?

A) Predicted value: 13.1
Residual: 0.9
B) Predicted value: 11.8 Residual: 0.2
C) Predicted value: 15.7 Residual: 1.3
D) Predicted value: 18.3 Residual: 0.7

Answers

Answer:

A) Predicted value: 13.1   Residual: 0.9

Step-by-step explanation:

By definition:

residual = observed - predicted

The linear model is:

f(x) = 1.3x + 9.2

where f(x) is the height and x is the age of the tree.

Replacing with x = 3:

f(x) = 1.3(3) + 9.2 = 13.1 ft

which is the predicted value. The observed value is 14 ft, then:

residual = 14 - 13.1 = 0.9 ft
