Answer:

slope = -1

Step-by-step explanation:

slope formula: (y2-y1)/(x2-x1)

(1-2) divided by (9-8) = -1/1 = -1

slope = -1

you can switch it up by doing (9-8) divided by (1-2), but it won't make a difference I think.

two bags contains 10 balls each. Every round you choose with equal probability one of the two bags and pick out a ball. After a

Stells [14]

Answer:

6.10%

Step-by-step explanation:

For every round since we are choosing with equal probability, then the probability of choosing from either of the bags is 1/2

Here, this scenario is only possible when a particular bag has been chosen 10 times and the other bag has been chosen 6 times ( meaning a particular bag has been emptied and for a particular bag to be emptied, all of its content would have been picked)

Now on the 17th trial, an empty bag is chosen

Therefore the required probability will be;

16C0 * (1/2)^10 * (1/2)^6 * 1/2 = 0.0610 = 6.1%

Sirgeo wants to fence in a circular portion of his backyard for a place space for his dog. Determine the area of the largest por

pickupchik [31]

Answer:

412.7 square feet

Step-by-step explanation:

A circle of circumference 72 ft will have a radius given by ...

C = 2πr

(72 ft) = 2(3.14)r

r = (72 ft)/(6.28) ≈ 11.465 ft

The area of a circle with that radius is ...

A = πr² = 3.14(11.465 ft)² ≈ 412.7 ft²

Sirgeo can enclose a circular area of about 412.7 square feet with 72 feet of fence.
