If grade point average rises as number of hours watching tv falls, the correlation between GPA and TV is

Answers

Answer 1

Answer: If the grade point average (GPA) rises as the number of hours spent watching TV falls, the correlation between GPA and TV is likely negative or inversely correlated. This means that as one variable (TV watching) decreases, the other variable (GPA) tends to increase. Negative correlation is represented by a negative correlation coefficient, typically ranging from -1 (perfect negative correlation) to 0 (no correlation). In this case, the correlation coefficient would be less than 0 but greater than -1.

6 • 6 • 6

Answers

The answer is 6^3

6*6*6= 216

6^3= 216

Final answer:

The given multiplication of 6 • 6 • 6 can be represented using an exponent as 63. The exponent is 3 because the number 6 is being multiplied by itself three times.

Explanation:

In mathematics, the operation of repeated multiplication is often represented using exponents. When you multiply a number by itself repeatedly, the way to express that using exponents is to write the base number and an exponent showing how many times the base number is being multiplied. In your example, you are multiplying 6 by itself 3 times, so the expression that represents this using exponents is 63.

Suppose you invest $580 at 10% compounded continuously , write an exponential function to model the amount in your investment account ?

Answers

Interest=percent times rate(in years) times principal.
Or I=PRT
So you invest $580 so I=$580 Rate would be .10 and time would be 1 for one year. So if you put this into the formula you get
$580=P(.65)(1)
So $580=.65P so $580/.65=P so P is approximately $892.31 per year.

The amount of time needed to complete a certain road trip, t, varies inversely with the speed of avehicle, s. At a speed of 68 miles per hour, the trip will be complete in 15 hours. What would the
speed of the car have to be to complete the trip in 17 hours?

Answers

The speed of car must be 60mile/hour, so that the trip will complete in 17 hours.

What is speed?

The rate of change of position of an object in any direction is called speed.

How do you calculate speed when distance and time is given?

$speed = (distance)/(time)$

According to the given question

At a speed of 68 miles per hour, the trip will be complete in 15 hours.

⇒ Total distance covered in 15 hours = 68 × 15 = 1,020 miles

( because, distance = speed × time)

Therefore, the speed of car to complete the trip in 17 hours

= $(1020)/(17) =60miles/hr$

Hence, the speed of car must be 60mile/hour, so that the trip will complete in 17 hours.

Answer:

x = 60

Step-by-step explanation:

t = $(k)/(x)$

15 = k/68

k=1020

~~~~~~~~~~~

17 = 1020/x

x = 1020/17

x = 60

Find the coordinates of the vertices of the triangle after a reflection across the line x= -1 and then across the line y = 1.F(-2,-3), G(-3,2), H(1,-1)

Answers

Answer:

a. F'(0, 5), G'(1, 0), H'(-3, 3)

Step-by-step explanation:

Reflection across x = -1 gives you the transformation ...

(x, y) ⇒ (-2 -x, y)

Reflection across y = 1 gives you the transformation ...

(x, y) ⇒ (x, 2 -y)

Together, these give you the transformation ...

(x, y) ⇒ (-2 -x, 2 -y)

Applying this to point F, we have ...

F(-2, -3) ⇒ F'(-2 -(-2), 2 -(-3)) = F'(0, 5) . . . . . . matches choice A

_____

How we found the transformation

In general, if M is the midpoint between A and B, then you have ...

M = (A+B)/2

2M = A+B

B = 2M - A

So, if we want x=-1 to be the midpoint between x' and x, then we have ...

x' = 2(-1) -x = -2 -x

Likewise, if we want y=1 to be the midpoint between y' and y, then we have ...

y' = 2(1) -y = 2 -y

So, the transformation is ...

(x, y) ⇒ (x', y') = (-2 -x, 2 -y)
