Cory Is A Bird Watcher He Estimates That 30% Of The Birds He Sees Are American Robins, 20% Are Dark Eyed

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

Answer:

2nd answer choice

Step-by-step explanation:

First, you see which inequalities are represented in the graph. When doing this,  I just temporarily the signs to equal signs so just basically ignore the inequalities. Then, when you find the ones with the right numbers, you can worry about the inequalities. Remember that greater than is always the side where the y values increase and less than is always where the numbers on the y axis decrease. Also, pay attention to the equal than sign. If it has a line under the sign, the line has to be solid while if there is no line, then it is dashed. In this problem, The first equation represents the dashed line and the second is the solid line.

Bill is making accessories for the soccer team. He uses 777.35 inches of fabric on headbands for 32 players and 3 coaches. He also uses 301.76 inches of fabric on wristbands for just the players. How much fabric was used on a headband and wristband for each player?

Answers

Answer:

Fabric used on a headband for each player = 22.21 inches

Fabric used on a wristband for each player = 9.43 inches

Step-by-step explanation:

Let fabric used on each headband = [tex]h[/tex] inches

Let fabric used on each wristband = [tex]w[/tex] inches

Number of players for which headband is made = 32

Fabric used on 32 players = 32[tex]h[/tex] inches

Number of coaches for which headband is made = 3

Fabric used on 3 coaches = 3[tex]h[/tex] inches

As per question statement:

Total fabric used on headbands = 777.35 inches

[tex]32h + 3h = 777.35\\\Rightarrow 35h = 777.35 inches \\\Rightarrow h = 22.21\ inches[/tex]

Number of players for which wristband is made = 32

As per question statement:

Fabric used on wristbands = 301.76 inches

[tex]32w = 301.76\\\Rightarrow w = 9.43\ inches[/tex]

Therefore, the answer is:

Fabric used on a headband for each player = 22.21 inches

Fabric used on a wristband for each player = 9.43 inches

Solve for x:
3x – 2 (5 – x) = 30

Answers

Answer:

x = 8

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Step-by-step explanation:

Step 1: Define Equation

3x - 2(5 - x) = 30

Step 2: Solve for x

Distribute -2:                    3x - 10 + 2x = 30Combine like terms:        5x - 10 = 30Isolate x term:                  5x = 40Isolate x:                           x = 8

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Substitute in x:                    3(8) - 2(5 - 8) = 30Multiply:                               24 - 2(5 - 8) = 30Subtract:                              24 - 2(-3) = 30Multiply:                               24 + 6 = 30Add:                                     30 = 30

Here we see that 30 does indeed equal 30.

∴ x = 8 is the solution to the equation.

Answers

Answer: 81%

Step-by-step explanation:

From the question, we are informed that Samuel scored a 32.5/40 on his most recent math test.

Based on the values given, to convert it to percentage, we have to multiply the score by 100. This will be:

= 32.5/40 × 100

= 3250/40

= 81.25%

Answers

Answer:

P(A) = {{a},{b},{c},{a,b},{a,c},{b,c},{a,b,c},∅}

Step-by-step explanation:

➨ Power Set is the set of all subsets.

First, find the subset of A.

{a},{b},{c},{a,b},{a,c},{b,c},{a,b,c},∅

If you aren't sure that you already have written all subsets or not, use the following formula.

[tex]2^n[/tex] ➩ where n is the number of element/members.

Our number of members are 3, use the following formula.

[tex]2^3=8[/tex]

Thus, our subsets should be 8.

As we've already gathered all subsets, write the braces all whole subsets.
