Cory is a bird watcher he estimates that 30% of the birds he sees are american robins, 20% are dark eyed juncos and 20% are slnc sparrows. he designs a simulation.

Answers

Answer 1

Answer:

I think C. 0.75

Step-by-step explanation:

Answer 2

The probability of seeing at least one robin in the next 5 birds is 0.75

How to determine the probability?

The representations are given as:

American robins = 0 to 2Dark eye juncos = 3 and 4Song sparrows = 5 and 6Others = 7 to 9

Using the above representations, the numbers that represent an occurrence of seeing at least one robin in the next 5 birds are:

05716 16803 32177 92290 72794 14333 79019 05943 77510 74051 87238 86481 94036 12749 24005

The number of occurrence is:

Number = 15

The number of simulation is 20

So, the probability of seeing at least one robin is:

P = 15/20

Divide

P = 0.75

Hence, the probability of seeing at least one robin is 0.75

If the perimeter of the triangle is 60, what is the value of y?

Answers

Answer:

y = 5

Step-by-step explanation:

Given:

In the right triangle the hypotenuse is 5y, one leg is 4y, the other leg is missing

Missing side of the triangle is:

√(5y)² - (4y)² = √(3y)² =3y

Perimeter is 60:

3y + 4y + 5y = 6012y = 60y = 60/12y = 5

Can anyone please help me with these questions 2. a-b 3. a-b 4. a-b and number 5?

Answers

9514 1404 393

Answer:

2a. 0.7, 0.3, -0.1, -0.5, -0.9

2b. 1, 3, 9, 27, 81

3a. geometric; r = 1/5

3b. arithmetic; d = -9

4. 234

5. 1/32

Step-by-step explanation:

2a. Start with the first term and add the common difference to get the next term.

0.7

0.7 -0.4 = 0.3

0.3 -0.4 = -0.1

-0.1 -0.4 = -0.5

-0.5 -0.4 = -0.9

The first 5 terms are 0.7, 0.3, -0.1, -0.5, -0.9.

2b. Start with the first term and multiply by the common ratio to get the next term.

The first 5 terms are 1, 3, 9, 27, 81.

3a. Obviously, the difference between 40 and 8 is not the same as the difference between 8 and 1.6. So, we look to see if the ratios are the same. They are:

8/40 = 1.6/8 = 1/5

This is a geometric sequence with a common ratio of 1/5.

3b. If the sign changes, but does not alternate, it cannot be a geometric sequence. The common difference is ...

-5 -4 = -14 -(-5) = -9

This is an arithmetic sequence with a common difference of -9.

4. Use n=50 and evaluate.

[tex]a_{50}=-11+5(50-1)=\boxed{234}[/tex]

5. Use n=7 and evaluate.

[tex]g_7=2\cdot\left(\dfrac{1}{2}\right)^{7-1}=\dfrac{2}{2^6}=\dfrac{1}{2^5}=\boxed{\dfrac{1}{32}}[/tex]

X=22

Step-by-step explanation:

All the angles in every triangle must add up to 180 so we can subtract 23 and 135 from 180 to get 22.

Answer:

x=22

z=135

y=23

Step-by-step explanation:

First, start with x in the picture. All angles in a triangle add up to 180 degrees. So, add 135+23 and then subtract that from 180.

135+23=158

180-158 = 22 degrees

Angle z is congruent to the larger angle on the other triangle. So, that means z=135.

Angle y is equal to the angle across from it. Y=23
