99 points fast museum surveyed three groups of 5 members to find out how many times the members visited the zoo in the past year. the table shows the results of the three samples.
survey visits to the museum
group 1 {4, 10, 6, 3, 8}
group 2 {3, 1, 2, 1, 2}
group 3 {7, 9, 3, 4, 7}

the sporting goods store has 1225 customers one weekend

Hello!

I believe the answer is 6 visits.

I hope it helps!

*Hello there!*~

The answer is:

6.1

rounded the answer will be 6.

*Hopes this helps you!*~

60: 45 =12: 9 =4: 3 so the answer is 4: 3

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)
