The table shows the number of calories in four meals and the cost of each meal.
Aleksandr-060686 [28]

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

How to factor this expression <br><br>x^3 - 4x^2 + 4x - 16
Natalija [7]
X²(x - 4) +4 (x - 4)

(x² + 4) (x - 4)

First find the common terms that can enter into both x³ and 4x² then write its down in this case it’s x² that can enter x³ leaving only x _since x³/x² = subtract of the indices. x² will also enter 4x² leaving only four hence you having x² (x - 4)
then do the same for the next pair of terms giving you 4 that can enter into both 4 and 16
Leaving you with +4 (x - 4)

Now you can put the common terms together like so (x² + 4) and choose get one of the other two which are the same= (x - 4)
= (x² + 4) (x - 4)

natta225 [31]
4*25= 100. There are 26 tables. At each of the 25 tables 4 people are sitting. Which means 100 people are sitting in complete tables of 4 people. That means that at the 26th table 3 people are sitting. 103-100= 3. Hope that helps. :)
