Answer:

A

Step-by-step explanation:

20.00 * .15

.15 = 15 out of 100 = 15%

Given:

The regression equation for change in temperature, y, to amount of rain, r, is given by

[tex]\hat{y}=0.2-1.4r[/tex]

The observed amount of rain was 0.4 inches and the temperature change was 2.3 degrees.

To find:

The residual and interpret it.

Solution:

According to the question, the observed amount of rain was 0.4 inches and the temperature change was 2.3 degrees.

So, the actual value is 2.3 degrees.

Put r=0.4 in the given equation, to find the predicted value.

[tex]\hat{y}=0.2-1.4(0.4)[/tex]

[tex]\hat{y}=0.2-0.56[/tex]

[tex]\hat{y}=-0.36[/tex]

We know that,

Residual = Actual value - Predicted value

[tex]Residual=2.3-(-0.36)[/tex]

[tex]Residual=2.3+0.36[/tex]

[tex]Residual=2.66[/tex]

Residual is positive because predicated value is less than the actual value.

So, the regression line underpredicts the temperature change.

Therefore, the correct option is B.

The dilation is solved and the scale factor of line is A'B' = 3AB

Resizing an item uses a transition called Dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size. Dilation transformations ensure that the shape will stay the same and that corresponding angles will be congruent

The result of dilation is that the shapes and boundaries of objects in the input image are expanded or thickened. It is often used in conjunction with other morphological operations such as erosion, opening, and closing to manipulate and enhance images.

Given data ,

Let the scale factor of the dilation be represented as k

Now , the scale factor k = 3

So , the ratio of the corresponding sides is given by

A'B' / AB = 3

Multiply by AB on both sides , we get

A'B' = 3AB

Hence , the dilation is simplified as A'B' = 3AB

Answer:

12a3 + 2a2 + 23a + 18

Step-by-step explanation:

Vertical multiplication works well when you have a binomial times a trinomial.

Multiply 2 times the trinomial and get 8a2 - 4a + 18 then multiply 3a times the trinomial to get 12a3. -6a2 + 27a

Then combine like terms.

The product of the givens expressions is 12a³ + 2a² + 23a + 18.

The product of the givens expressions is obtained by multiplying all the variables in the bracket as shown below.

(3a + 2)(4a² – 2a + 9) = 3a(4a² – 2a + 9) + 2(4a² – 2a + 9)

= 12a³ - 6a² + 27a + 8a² - 4a + 18

simplify by collecting similar terms together

= 12a³ + 2a² + 23a + 18

Thus, the product of the givens expressions is 12a³ + 2a² + 23a + 18.

Answer:

(-7)2 = -14

Step-by-step explanation:

The parenthesis basically mean "multiply". So, this is a simple equation meaning -7 x 2. And remember, anytime we multiply a positive by a negative, you get a negative. So, simply multiply 7 x 2 = 14 and add a negative sign to make the solution true. So, -7 x 2 or (-7)2 = -14

Hope this helps! If you have any additional questions, please don't hesitate to ask me or your teacher to be sure you master the subject. Also thank you for the generous points!! Stay safe and please mark brainliest!!

Answer:

-14

Step-by-step explanation:

just act as if -7 were positive then you know 7x2 = 14 cause' "()" means multiplication.

last, since 7 was negative in the first place then you turn your product back to a negative and you get -14

Answer: Answer And explanation in picture

Step-by-step explanation:

The time which takes the call is $5.00 with the given ratio is 50 minutes.

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

Given that,

$0.10 for 1 minute

The ratio of time to cost = 1/0.10 = 10

Let's say the time taken in $5 is x minutes

The ratio of time to cost = x/5

x/5=10

x = 50 minutes

Hence "The time which takes the call is $5.00 with the given ratio is 50 minutes".
