The scatter plot shows the number of minutes guya practiced the flute each day in a given week.

what is guya's mean practice time per day during the given week? round to the nearest tenth, if necessary.

35 min
35.6 min
35.7 min
40 min

you for your ! picture is attached below.

The plot tells us that Guya practiced 10 minutes on Sunday, 30 minutes on Monday, etc.

So, in the whole week she practiced

minutes.

The mean of a set of numbers is defined as the sum of the numbers divided by the cardinality of the set. So, we have seven numbers adding up to 250, and the mean is thus

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
