Step-by-step explanation:

Write a rule to describe the transition of a point from (-3,3) to (-2,2)

In the answers, we see that the rule must be formatted as:

(x,y) ⇾ (x _ 1, y _ 1)

Soo . . we take the first x (-3) and the second x (-2) and try the 2 methods:

-3 - 1 = -4

-3 +1 = -2

So we see that the first one has to + 1

Here's the rule so far.

(x,y) ⇾ (x + 1, y _ 1)

Next, take the first y (3) and the second y (2) and repeat the 2 methods:

3 + 1 = 4

3 - 1 = 2

Here we get that we have to - 1

Therefore, the rule to describe the transition of a point from (-3,3) to (-2,2) is:

(x,y) ⇾ (x + 1, y - 1)

Which is option 4 or D.

Hope this helps you understand a bit better! =)

Answer the following questions.

serg [7]

39 is 312% of 12.5

To find this you just divide 12.5 into 39 which gives you 3.12. To change that to a percentage you multiply by 100 which gives you 312%

7.5 is 102% of 7.38

To find this you just divide 7.38 into 7.5 which gives you 1.0162, which I rounded to 1.02. To change that to a percentage you multiply by 100 which gives you 102%

I hope this helped! :)

Solve for the variable using Trig ratio.

SIZIF [17.4K]

Answer:

x = 3.86

a = 5.86

Step-by-step explanation:

From the triangles attached,

By applying cosine rule in triangle 1,

cos(50)° = $\frac{\text{Adjacent side}}{\text{Hypotenuse}}$

cos(50)° = $\frac{x}{6}$

x = 6cos(50)°

x = 3.86

Now we apply sine rule in the second triangle,

sin(23)° = $\frac{\text{Opposite side}}{\text{Hypotenuse}}$

sin(23)° = $\frac{a}{15}$

a = 15sin(23)°

a = 5.86

We expect that students who do well on the midterm exam in a course will usually also do well on the final exam. Gary Smith of P

dybincka [34]

Using the model equation, the predicted mean score on the final given a score of 10 points above the class mean in the mid term exam is 50.7

The Least - Square Regression equation which models the relationship between midterm and final exam score is :

γ=46.6 + 0.41x

x = 10 points ; substitute the value of x = 10 into the regression equation ;

γ=46.6 + 0.41(10)

γ=46.6 + 4.1

γ = 50.7

The number of points above the mean he'll score in the final exam is predicted to be 50.7

Janet scored 200 and 400 points in the first 2 rounds of a computer game.

7nadin3 [17]

Answer:

B. $(200+400)-250=p$

Step-by-step explanation:

Let p be number of points Michael needs to score in 2nd game to catch up.

We have been given that Janet scored 200 and 400 points in the first 2 rounds of a computer game. So the total points scored by Janet in two games will be: $(200+400)$ points.

We are also told that Michael had scored 250 points in the first round and he want to get the same total score as Janet.

So we can find the number of points Michael needs to score to catch up Janet by subtracting the number of points scored by Michael in 1st game from total number of points scored by Janet in two games. We can represent this information in an equation as:

$(200+400)-250=p$

Therefore, the equation $(200+400)-250=p$ will help Michael to find the number of points he need to catch up Janet and option B is the correct choice.
