Even if you don't solve for the correlation coefficient, you can already solve this by process of elimination and inspection. The correlation coefficient has a positive value, therefore, it's not D. Looking at the data, you can see a trend in the values; as one data increases, the other increases as well. Therefore, the dependency of the variables is strong and the correlation coefficient must be close to 1. So, the answer is B.

Lesson 7: Scatter Plots and Regression Lines

Which type of correlation by the scatter plot?

B. Negative Correlation

Which type of correlation by the scatter plot?

D. No Correlation

What is the correlation coefficient for the set of data?Round your answer to the nearest thousandth?

B. 0.989

About how tall would expect of these trees to be after 22 years?

C. 44.25

You use a line of best fit for a set of data to make a prediction about an unknown value.The correlation coefficient for your data set is -0.993. How conflict can you be that your predicted value will be reasonably close to actual value?

C. I can be very confident; it will be close, but it probably won't be exactly.

1. The image below represents three planters that are filled with soil. Find the total volume of soil in the three planters. Pla
Alisiya [41]

Answer:

327 inches³

Step-by-step explanation:

Planter A volume = (14 × 3 × 4) inches

= 168 inches³

Planter B volume = (9 × 3 × 3) inches

= 31 inches³

Planter C volume = (3 × 3 × 13) inches

= 78 inches³

Total volume = (168 + 81 + 78) inches

= 327 inches³

Hope this helps and have a nice day

valkas [14]

Hi ;-)

-10\dfrac{2}{7}:(-4\dfrac{4}{11})=-\dfrac{10\cdot7+2}{7}:(-\dfrac{4\cdot11+4}{11})=\\\\\\=-\dfrac{70+2}{7}:(-\dfrac{44+4}{11})=-\dfrac{72}{7}:(-\dfrac{48}{11})=-\dfrac{72}{7}\cdot(-\dfrac{11}{48})=\dfrac{99}{42}=\boxed{2\frac{15}{42}}

What is the true solution to l n 20 l n 5 = 2 l n x
Genrish500 [490]

Since the solution cannot be negative hence the true solution to the expression is x = 10

<h3>Laws of logarithm</h3>

Given the logarithmic expression

ln 20 + ln 5 = 2lnx

In logarithmic law, the sum of log is equivalent to its product .The equation above can be written as:

ln(20*5) = 2lnx
ln100 =2lnx
ln100 = lnx^2

x^2 =100

x = 10

Since the solution cannot be negative hence the true solution to the expression is x = 10

Identify the factors of x2 − 4x − 12.
Alborosie
(x-6)(x+2)

When you foil it you get x^2+2x-6x-12
After you do this you then add like terms to get x^2-4x-12
Therefore the answer (x-6)(x+2) is correct.
