Answer:

The mean for Brand B is higher than the mean for Brand A.

Step-by-step explanation:

The mean is the average. The average is found by adding all the numbers together, and dividing by the number of numbers.

There are 10 dots on each plot.

BRAND A: 1000+(1100•2)+(1200•3)+(1300•4) = 12,000

Divide by 10.

BRAND A MEAN: 1,200

BRAND B: 1400+(1500•4)+(1600•2)+)1700+1800+1900= 16,000

Divide by 10.

BRAND B MEAN: 1,600

What’s the area of this figure?

Answers

Answer:

374 mm

Step-by-step explanation:

There are two rectangles and one triangle. This means that we need to add the sum of two rectangles and one triangle together.

Rectangle 1:

19*9=171

Rectangle 2:

19*9=171

Triangle:

8*23*1/2=32

(We divide by 1/2 because it's a triangle)

Now we add them together.

171+171+32=374

In the end, the answer is 374. I didn't show all of my work because most of it was done mentally.

Yes. Since7^2+9^2≠11^2, the triangle must be a right triangle.

No. Since 7^2+9^2=11^2, the triangle cannot be a right triangle.

Answers

9514 1404 393

Answer:

No. Since 7^2 + 9^2 ≠ 11^2, the triangle cannot be a right triangle.

Step-by-step explanation:

You may recall that side lengths of 3, 4, 5 make a right triangle. That particular triple has several interesting characteristics. One is that it is the only (reduced) triple that is an arithmetic sequence (has a constant difference between the side lengths). Any right triangle that has sides that differ by a constant amount must be a multiple of 3, 4, 5.

Here, we have sides of length 7, 9, 11—values that differ by 2. They form an arithmetic sequence that is not a multiple of 3, 4, 5, so we know right away they cannot be sides of a right triangle.

If we want to use the Pythagorean relation to check, we can see if the equation is true:

7² + 9² = 11²

49 + 81 = 121

130 = 121 . . . . . . Not True

Solve the equation:
3x + 1 over 4y2
