A bag contains three blue marbles, five red marbles, and four green marbles.

Part A: What is the probability of selecting a red marble?

Part B: What is the probability of selecting three red marbles without replacement?

Part C: In a short paragraph, explain in your own words your work to Step B

Answers

Answer 1

Answer:

Below.

Step-by-step explanation:

The total number of marbles is 12.

Part A.

Prob(Red marble) = 5/12.

Part B.

Prob(pick 3 red marbles without replacement) = 5/12 * 4/11 * 3/10 = 1/22.

Part C.

The probability of the first being red is 5/12 because there are 5 red out of a total of 12 marbles. After that there are only 4 marbles and the total is 11 ( 1 marble less). Finally on the 3rd pick there are 3 red and a total of 10. WE then multiply these 3 probabilities.

In the Everglades National Park in Florida, there are 200 species of birds that migrate. This accounts for !" of all the species of birds sighted in the park. A. Write an equation to find the number of species of birds that have been sighted in Everglades National Park. B. There are 600 species of plants in Everglades National Park. Are there more species of birds or plants in the park? Explain.

Answers

Answer:

A)[tex]\frac{4}{7} y = 200[/tex]

B) There are more species of plants as the number of species of birds that have been sighted in Everglades National Park is 280

Step-by-step explanation:

Total number of species of birds that migrate = 200

We are given that [tex]\frac{4}{7}[/tex] of all the species of birds are sighted in the park

a)Write an equation to find the number of species of birds that have been sighted in Everglades National Park.

Let y be the number of species of birds that have been sighted in Everglades National Park.

We are given that[tex]\frac{4}{7}[/tex] of all the species of birds are sighted in the park

So,  [tex]\frac{4}{7} y = 200[/tex]

[tex]y = \frac{200 \times 7}{4}[/tex]

y=280

B)There are 600 species of plants in Everglades National Park. Are there more species of birds or plants in the park?

So, There are more species of plants as the number of species of birds that have been sighted in Everglades National Park is 280

Step-by-step explanation:

3m + 1 = 10

this is a ixl question and i need the answer it’s inequalities and equations 7 grade

Answers

3m+1=10
so you’d do -1 on both sides so. 1-1 and 10-1
then it’d be 3m=10
you want the variable (m) by its self. so you’d divide 3 by both sides.
so 3 divided by 3 and 10/3
so it’d be m=10 over 3 (fraction ten on top 3 on bottom) or m=3.3(the three after the decimal is repeated)

9514 1404 393

Answer:

  m = 3

Step-by-step explanation:

Notice what has been done to the variable. It has been multiplied by 3, then 1 is added to the product.

We solve an equation like this by undoing those operations, in the reverse order. First, we undo the addition of +1 by adding -1 (the opposite of +1) to both sides of the equation.

  3m + 1 - 1 = 10 - 1

  3m = 9 . . . . . . . . . simplify

__

Now, we undo the multiplication by 3 by multiplying by the "multiplicative inverse" or reciprocal, 1/3. This is the same as dividing by 3.

  (1/3)(3m) = (1/3)(9)

As before, we do this to both sides of the equation.

  m = 3 . . . . . . . . . simplify

The solution is m = 3.

_____

The rule for equations is that you must do the same operation to both sides of the equation in order for it to remain valid. (The same is true for inequalities, with a special rule for multiplication or division by a negative number. Doing that reverses the comparison symbol: < ⇔ > or ≤ ⇔ ≥.)

Quest 6. let No. of cells = Nc, let No. of Hours = Nh.

then Nc = (6hrs x 2cells)/1hr = 12 cells.

if 1,024 cells, then

Nh = (1hrs x 1,024cells)/2hrs = 512 hrs.

Quest 7. No, cos 10^7 is only 10,000,000, so 39 & 10 million are not any way equal.

Quest 8. 1 = 1^3, 8 = 2^3, 27 = 3^3, 1 = 1^3, 64 = 4^3, 125 = 5^3,

Quest 9. 2^8 = 2 x 2 x 2 x 2 x 16 = 256, this cos 256 is a product of 8, 2s & there are 4, 2s in 16.

so altogether its all 8, 2s.

Answers

Answer:

The product st is irrational.

The product pt is irrational.

Step-by-step explanation:

Let p = 3/4 and q= 5/9

Now multiplying these two non zero rational numbers

3/4 (5/9)= 15/36 ( this is also a rational number)

An irrational number is one which cannot be expressed in the form of p/q where p and q are integers( in the form of a simple expression) like the rational number.

Now let the two irrational numbers  s and t be √3 and √5

Now multiplying the two irrational numbers we get

st = √3  √5

st =√15  ( this is also an irrational number)

√15 cannot be expressed in the form of a simple fraction.

Now multiplying pt

3/4 * √5= 3√5/4  ( this is also irrational)

A ticket to a baseball game costs $32. Each soda at the game costs $4. Shawn may spend no more than $50. He buys 1 ticket and x sodas. (ignore what I wrote already i think it’s wrong)

Answers

Answer:

32 + 4x ≤ 50

Step-by-step explanation:

Cost of tickets = $32

Cost of soda = $4

Total spent = $50

When we say "no more than", we mean less than or equal to (≤)

He buys 1 tickets and x sodas

32 + 4x ≤ 50

4x ≤ 50 - 32

4x ≤ 18

Divide both sides by 4

x ≤ 18 / 4

x ≤ 4.5

Shawn can buy more than 4 sodas

1. What is the wavelength of a radio wave broadcast at 150 MHz?

Answers

Hope this helps..........

The value of the wavelength will be equal to 2 meters.

It is given that a radio is broadcasting at 150 MHz .

We have to calculate the wavelength.

What is the formula for wavelength ?

The wavelength is given by L = c/f , where c = speed of wave and f is the frequency of wave.

L = c/f

Let's assume c = 3 × 10^8

Given that frequency (f) is 150 MHz .

Wavelength (L) is approximately ;

L= (3 × 10^8 )/ (150,000,000)

L= 2 meters

Thus, the wavelength of a radio wave broadcast at 150 MHz will be equal to 2 meters.

Answers

Answer:

a set of points that pair input values with output values

Step-by-step explanation:

The set of points that relate, input values with output values.

A relation is a set of points that pair input values with output values.

Therefore the correct option is C.

In mathematics, a relation is a set of ordered pairs, where each pair consists of an input value (x) and an output value (y) that are related to each other in some way.

These ordered pairs represent the relationship between the input and output values of the relation.

So, a relation can be represented as a set of points in the coordinate plane, where each point represents an ordered pair (x, y). The relation itself is not specifically the input (x) values or the output (y) values, but rather the collection of all the paired values.

Therefore the correct option is C.
