**Answer 1**

**Answer:**

4 units

**Step-by-step explanation:**

**Given**

[tex]G = (4,2)[/tex]

[tex]E = (1,-2); F = (7,-2)[/tex]

**Required**

Determine the distance

**We need to calculate the equation of EF**

But first, we calculate the slope (m)

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

**Where**

[tex](x_1,y_1) = (1,-2)[/tex]

[tex](x_2,y_2) = (7,-2)[/tex]

**So:**

[tex]m = \frac{-2 - (-2)}{7 - 1}[/tex]

[tex]m = \frac{0}{6}[/tex]

[tex]m = 0[/tex]

**The equation is then calculated as:**

[tex]y - y_1 = m(x - x_1)[/tex]

**Where**

[tex]m = 0[/tex]** and **[tex](x_1,y_1) = (1,-2)[/tex]

[tex]y - (-2) = 0(x - 1)[/tex]

[tex]y +2 = 0[/tex]

**So, we are to calculate the distance between point **[tex]G = (4,2)[/tex]** and line **[tex]y +2 = 0[/tex]

**The distance is calculated using:**

[tex]d = \frac{|Ax_1 + By_1 + c|}{\sqrt{A^2 + B^2}}[/tex]

**In **[tex]G = (4,2)[/tex]**, we have:**

[tex](x_1,y_1) = (4,2)[/tex]

**A general equation has **[tex]Ax + By + c = 0[/tex]** as its format**

**By comparison**

[tex]A = 0[/tex]

[tex]B = 1[/tex]

[tex]c = 2[/tex]

[tex]d = \frac{|Ax_1 + By_1 + c|}{\sqrt{A^2 + B^2}}[/tex]** becomes**

[tex]d = \frac{|0 * 4 + 1 * 2 + 2|}{\sqrt{0^2 + 1^2}}[/tex]

[tex]d = \frac{|0 + 2 + 2|}{\sqrt{0 + 1}}[/tex]

[tex]d = \frac{|4|}{\sqrt{1}}[/tex]

[tex]d = \frac{4}{1}[/tex]

[tex]d = 4[/tex]

**Hence, the distance is 4 units**

Empathy means being able to understand what others feel. To see how the brain expresses empathy, researchers recruited 16 couples in their midtwenties who were married or had been dating for at least two years. They zapped the man's hand with an electrode while the woman watched, and measured the activity in several parts of the woman's brain that would respond to her own pain. Brain activity was recorded as a fraction of the activity observed when the woman herself was zapped with the electrode. The women also completed a psychological test that measures empathy.

Subject 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

Empathy Score 37 48 42 52 56 61 62 46 45 47 55 70 24 72 31 102

Brain Activity -0.12 0.389 0.018 0.363 0.012 0.406 0.106 0.52 0.15 0.744 0.246 0.568 0.216 0.721 0.369 0.79

Given that the equation for the regression line is ŷ = 0.00753x - 0.06759, what is the residual for subject 15?

### Answers

Answer:

the residual is 0.2032

Step-by-step explanation:

The regression line has been given as:

Y^ = 0.00753X-0.06759

The paired observation for X is (31, 0.369)

The value of X is the empathy score under subject 15 = 31

The value of the brain activity under subject 15 is 0.369

So we have y^ = 0.00753(31) - 0.06759

= 0.1658

Then the residual = y - y^

= 0.369 - 0.1658

= 0.2032

Therefore the residual is 0.2032

4x+6y=24

### Answers

**Answer:**

The lines are parallel.

**Step-by-step explanation:**

Given the lines

[tex]-2x-3y=9[/tex]

[tex]4x+6y=24[/tex]

Writing the equations in the slope-intercept form

[tex]y=mx+b[/tex]

where m is the slope and b is the y-intercept

[tex]-2x-3y=9[/tex]

[tex]y=-\frac{2}{3}x-3[/tex]

Thus, the slope = m₁ = -2/3

also

[tex]4x+6y=24[/tex]

[tex]y=-\frac{2}{3}x+4[/tex]

Thus, the slope = m₂ = -2/3

We know that parallel lines have equal slopes

As

m₁ = m₂

Thus, the lines are parallel.

A. 3

B. 6

C. 9

O

OD. 12

### Answers

**Answer:**

The answer is 9

**Step-by-step explanation:**

3X3X3=9 because she said she wanted to make it 3 TIMES larger

**Area of enlarged garden** is **9 **times the **area of the original garden**.

What is Area?

" **Area** is the space occupied by an object which is two dimensional in shape."

**Formula used to find Area**

**Area of a rectangle = Length × Width**

Let 'l' be the length of the garden.

And 'b' be the width of the garden.

According to the question,

New length = 3l

New Width = 3b

**Area of original garden** = l × b

**Area of enlarged garden **= 3l × 3b

= 9 ( l × b )

= **9 × ( Area of original garden)**

Hence **Area of enlarged garden** is **9 **times the **area of the original garden**.

Complete the function digits(n) that returns how many digits the number has. For example: 25 has 2 digits and 144 has 3 digits

### Answers

Answer:

Step-by-step explanation:

We can get this done by using the code

def digits(n):

count = 0

if n == 0:

return 1

while (n > 0):

count += 1

n= n//10

return count

Also, another way of putting it is by saying

def digits(n):

return len(str(n))

------------------------------------------

print(digits(25)) # Should print 2

print(digits(144)) # Should print 3

print(digits(1000)) # Should print 4

print(digits(0)) # Should print 1

Doing this way, we've told the system to count the number of figures that exist in the number. If it's 1000 to 9999, then it records it as 4 digits. If it's 100 - 999, then it records it as 3 digits. If it's 10 - 99, it records as 2 digits. If it's 0 - 9, then it has to record it as a single digit.

Following are the **digits function** that calculte the **digits**:

**Program Explanation:**

In this question, we define two in which one use **predefine methods **and one is used for calculate value by logics, which can be defined as follows: Defining a method "**digits**" that takes "**n**" variable inside the parameter.Inside the method "**x**"variable that converts parameter value into string and counts its length value and use return keyword that return the length of x.Outside the method, a variable **n **is define that inputs value, and call the method and print its return value.

**Program:**

def digits(n):#defining a method digits that takes n variable in the parameter

x=len(str(n))#defining a variable x that converts parameter value into string and counts its length value

return x#using return keyword that return the length of x

n=int(input("Ennter number: "))#defining a variable n that inputs value

print(n, "has", digits(n) ,"digits") #using print method that calls the digits method and print its value

**OR**

def digits(n):#defining a method digits that takes n variable in the parameter

x = 0#defining an integer variable x

if n == 0:#defining an if block that checks n value equal to 0

return 1#return value 1

while (n > 0):#defining a while loop that check n value grater than 0

x += 1#incrementing the value of x

n =n//10#calculating the digits

return x#return digits value

n=int(input("Ennter number: "))#defining a variable n that inputs value

print(n, "has", digits(n) ,"digits") #using print method that calls the digits method and print its value

What is probability?

Probability is defined as the **ratio **of the number of favourable outcomes to the total number of outcomes in other words the **probability **is the number that shows the happening of the event.

Probability = Number of favourable outcomes / Number of sample

Given that 4 cards are chosen at random from a deck of 52 cards without replacement.

The **probability **of choosing a ten, a nine, an **eight**, or a seven in order is calculated as,

Probability = ( 4 / 52 ) x ( 4 / 51 ) x ( 4 / 50 ) x ( 4 / 49 0
