Amélie runs a bakery. she wants to find out whether her cake sales are affected by the weather conditions. she recorded the daily temperature and the number of cakes she sold on different days of the year. the table shows the data she gathered.

daily temperature (°f) cakes sold
42 39
45 52
48 31
54 61
59 72
62 35
64 61
65 34
67 58
75 45
84 24
the correlation coefficient is close to .

based on this information, we can conclude that amélie's cake sales are affected by the daily temperature.

Step-by-step explanation:

Given that Amélie runs a bakery. She wants to find out whether her cake sales are affected by the weather conditions. She recorded the daily temperature and the number of cakes she sold on different days of the year

Let us find the correlation coefficient for the variables x, daily temperature and y, no of cakes sold.

xy

4239

4552

4831

5461

5972

6235

6461

r-0.197481837

Since r is nearer to 0 than to 1, we find that there is a negative very moderate correlation between the two variables.

We cannot conclude that  Amélie's cake sales are affected by the daily temperature.

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
