The correct answer is 2– it is NOT a possible value for correlation coefficient (r) because the value of “r” must always be between +1 and –1.

<h3>Answer:  A) 2</h3>

Explanation:

The correlation coefficient r has this range of values

-1 \le r \le 1

which can be stated as "r is between -1 and 1, including both endpoints".

As you can see, r = 2 is outside this range and not a possible correlation coefficient. The largest r can get is r = 1 to indicate perfect positive linear correlation.

On the other end of the spectrum, r = -1 means perfect negative linear correlation. In between, r = 0 means no linear correlation at all.

Solve for A<br> 3(4A + 4) = 3A + 8A + 1 + 8
kvasek [131]

Answer:

a=−3

Step-by-step explanation:

Let's solve your equation step-by-step.

3(4a+4)=3a+8a+1+8

Step 1: Simplify both sides of the equation.

3(4a+4)=3a+8a+1+8

(3)(4a)+(3)(4)=3a+8a+1+8(Distribute)

12a+12=3a+8a+1+8

12a+12=(3a+8a)+(1+8)(Combine Like Terms)

12a+12=11a+9

12a+12=11a+9

Step 2: Subtract 11a from both sides.

12a+12−11a=11a+9−11a

a+12=9

Step 3: Subtract 12 from both sides.

a+12−12=9−12

a=−3

Answer:

a=−3

kirill [66]
<span>The car has a starting value of $6300 and will depreciate by 8% of that original value per each ensuing year. This means that each year the value at the end of the year will be 92% of what it was when the year started. Thus we can write an exponential function for the value V(t) where t is the number of years after purchase, such that V(t) = 6300*(0.92^t). Substituting 4 years in for the value of t, we yield V(4) = 6300*(0.92^4) = $4513.</span>

A line passes through the points (2, 6) and (1, 4). What is its equation in slope-intercept form?
lara [203]

you can find the slope of this line by seeing how much change occurs. 2-1,6-4 therefore 1,2 rise over run. so the slope is 2. if we have the point 1,4 and we know the slope is 2 then we know it passes through 0,2 this is the y intercept. therefore y=2x +2
