Answer: The correct option is (B) K ∩ L ∩ M.

Step-by-step explanation: We are given to select the correct statement that describes the shaded region shown in the Venn-diagram.

From the Venn-diagram, we see that

there are three sets K, L and M represented as three circles.

We know that in a Venn-diagram, the area that is covered by two circles represents the common parts of both the sets.

So, the shaded region will represent the part that is common to all the three sets K, L and M.

Therefore, the shaded region is the intersection of the three sets L, L and M.

Thus, the shaded region describes K ∩ L ∩ M.

Option (B) is CORRECT.

What is the next number and why ? 1,3,11,35,99,_

Vladimir79 [104]

Answer: 241

Step-by-step explanation:

This is a simple problem when using Pascal's triangle. First you look at 1 - 3, what is the difference in these 2 numbers? Its 2, then you look at 3 and 11, the difference is 8, then 11 and 35, the difference is 24. If you keep doing this you get; 2 8 24 64 142. Next you find out how these numbers are different. In the end you keep doing this until you get to the triangles point or the differences converge.

1 3 11 35 99 241

2 8 24 64 142

6 16 40 78

10 24 38

14 14

In the end we get 14 but there is no difference in the numbers so we cant go any farther. Hope this helps!

Answer:

Area: 15.53 square inches

Perimeter: 15.71 inches

Step-by-step explanation:

Area:

So the area of the rectangle is pretty easy to find and is just the width * height. In this case it's 4 * 3 which is 12. Now the area of a circle is $\pi r^2$ . But since this is a semi circle it's half of that which is $\frac{\pi r^2}{2}$ . The diameter of the semicircle is 3 as it sits on top of the rectangle. The radius is half of the diameter so the radius is 1.5. Now plug that into the equation and you get $\frac{(3.14) (1.5)^2}{2} = 3.5325$ . Now add that to 12 and you get 15.5325. Round that number to the nearest hundredth and you get 15.53. So that's the area.

Perimeter:

Pi is the ratio of any circle's circumference to the diameter. Or in other words the circumference is equal to the diameter * 3.14. The diameter is 3 which you multiply by 3.14 to get the circumference of a circle. This will get you 9.42 but since it's a semicircle, the circumference is half of this value which is 4.71. The perimeter of the rectangle is just 2 times the width + 2 times the height. This is not completely the case in this shape since one of the sides of the rectangle is not a side of the two shapes joined together. Which is the side that is parallel to the side of length 3 inches. So the perimeter is going to be 2(4) + 3. This gives you 11 which you add to the 4.71 and get 15.71

Write an augmented matrix of each system. Then, solve each system using matrix notation. Describe the solution set in vector not

Naddik [55]

Answer:

The answer is below

Step-by-step explanation:

Given the system of equations:

x + y + 2z = 9

2x + 4y - 3z = 1

3x + 6y - 5z = 0

This system of equation can be solved using matrix. This done by first representing the equations as matrix and then solving:

The matrix form is:

$\left[\begin{array}{ccc}1&1&2\\2&4&-3\\3&6&-5\end{array}\right] \left[\begin{array}{c}x\\y\\z\end{array}\right] = \left[\begin{array}{c}9\\1\\0\end{array}\right] \\\\\\ \left[\begin{array}{c}x\\y\\z\end{array}\right] =\left[\begin{array}{ccc}1&1&2\\2&4&-3\\3&6&-5\end{array}\right] ^{-1} \left[\begin{array}{c}9\\1\\0\end{array}\right] \\\\\\$

$\left[\begin{array}{c}x\\y\\z\end{array}\right] =\left[\begin{array}{ccc}2&-17&11\\-1&11&-7\\0&3&-2\end{array}\right] \left[\begin{array}{c}9\\1\\0\end{array}\right] \\\\\\ \left[\begin{array}{c}x\\y\\z\end{array}\right] =\left[\begin{array}{c}1\\2\\3\end{array}\right]$

Which expression has the greatest value? A. 149.2 B. 149 - 16 C. 25 +16 D. 125.3

umka21 [38]

The answer would be A. If I subtracted 149 from 16, I would end up with 133, so it would not be B. If I added 25 to 16, that would equal 41, so that’s not the answer. Lastly, I wouldn’t choose D because 149.2 is greater than 125.3
Remember, any number before a decimal is considered a whole number.
