Answer:

A weak negative correlation

Step-by-step explanation:

$correlation, r = \frac{∑(y-\alpha)(x-\beta }{\sqrt{∑(y-\alpha)^2∑(x-\beta )^2 } }$

where,

$\alpha = \frac{∑y}{n} \\\beta =\frac{∑x}{n} \\∑ = summation$

$\alpha = \frac{3230}{4} = 807.5\\\\\\\beta =\frac{46}{4} = 11.5$

$therefore,\\\\r= -0.12924$

This represents a weak negative correlation

Find the 50th term for the sequence 31,24, 17

Nikitich [7]

9514 1404 393

Answer:

-312

Step-by-step explanation:

The general term of an arithmetic sequence is ...

an = a1 +d(n -1)

Here, you have first term a1 = 31, and common difference d = 24-31 = -7. So, the 50th term is ...

a50 = 31 -7(50 -1) = 31 -7(49) = -312

The 50th term for the sequence is -312.
