Mathematics
1 answer:
Oliga [24]3 years ago
5 0

Answer:

27.5cm^2

Step-by-step explanation:

you can cut the triangle to make two right triangles

so 11 is the height and the width is 2.5 since your cutting the triangle in half

so 11x2.5=27.5 since its a right triangle you have to divide by two 27.5/2=13.75

that's the answer for one of the triangles now multiply it by two since you need the two right triangle to make the other triangle so the answer is 27.5

What comes next in the sequence: 1, 3, 11, 43,
lianna [129]
There may be more than one solution, but if we take the difference between the numbers of the sequence, we get
3-1, 11-3, 43-11
=2,8,32
which are powers of 2
=2^1, 2^3,2^5
If we believe the next difference is 2^7=128, then the next in the sequence will be 43+128=171

Considering the given discrete probability distribution, it is found that the expected share is of 10%.

<h3>What is the mean of a discrete distribution?</h3>

The expected value of a discrete distribution is given by the <u>sum of each outcome multiplied by it's respective probability</u>.

In this problem, the distribution is given by:

  • P(X = 0.05) = 0.2.
  • P(X = 0.1) = 0.6.
  • P(X = 0.15) = 0.2.

Hence the expected value is given by:

E(X) = 0.2 x 0.05 + 0.6 x 0.1 + 0.2 x 0.15 = 0.1 = 10%.

The expected share is of 10%.

Answer:

x = 26 2/3 ~= 26.67

Step-by-step explanation:

Set up a proportion comparing like things.

It's easier to see if you write the small triangle separately.

See image.

I've done the calculation twice. Just look at the one that makes the most sense to you Obviously, it works out the same either way.
