1) Each lunch for a school field trip has a turkey, roast beef, or bologna sandwich, an orange or apple for a fruit, and a cookie or muffin for dessert. Amanda and Zack would like to…

-know the number of possible lunch options.

-P of having any meal with NO COOKIE.

(use sample space, tree diagram, and counting principle)

Answers

1) there are 12 possible lunch options. 2) the probability of having any meal with no cookie is 1/2 or 0.5.

How to find the number of possible lunch options.

1) Number of possible lunch options:

To determine the number of possible lunch options, we need to consider the choices for each component of the lunch.

- Sandwich: There are 3 options (turkey, roast beef, or bologna).

- Fruit: There are 2 options (orange or apple).

- Dessert: There are 2 options (cookie or muffin).

Using the counting principle, we multiply the number of options for each component together:

Number of possible lunch options = 3 (sandwich options) × 2 (fruit options) × 2 (dessert options) = 12.

Therefore, there are 12 possible lunch options.

2) Let's examine the favorable outcomes for each component:

- Sandwich: There are still 3 options (turkey, roast beef, or bologna).

- Fruit: There are 2 options (orange or apple).

- Dessert: There is 1 option (muffin, as we want to exclude cookies).

Using the counting principle, we multiply the number of options for each component together:

Number of favorable outcomes (no cookie) = 3 (sandwich options) × 2 (fruit options) × 1 (muffin option) = 6.

The total number of possible outcomes is still 12 (as calculated in the previous step).

Therefore, the probability of having any meal with no cookie is:

P(No cookie) = Number of favorable outcomes / Total number of possible outcomes = 6 / 12 = 1/2 or 0.5.

Hence, the probability of having any meal with no cookie is 1/2 or 0.5.

Answers

It’s “B” because if you multiply 82 and 76 you’ll get 6,232

The store has sold 6,232 laptops since it opened.

Option B is the correct answer.

We have,

Step 1:

Identify the number of laptops sold last month.

The problem states that the store sold 82 laptops in the past month.

Step 2:

Determine the total number of times the store has sold laptops since it opened.

The problem says that the store has sold 76 times the number of laptops sold last month.

So, we need to multiply 82 by 76.

82 laptops * 76

= 6,232 laptops

Thus,

The store has sold 6,232 laptops since it opened which is option B.

How can I find the cube root of 64?

Answers

Answer:

4

Step-by-step explanation:

The cube root of 64 is the number which when multiplied by itself three times gives the product as 64. Since 64 can be expressed as 2 × 2 × 2 × 2 × 2 × 2. Therefore, the cube root of 64 = ∛(2 × 2 × 2 × 2 × 2 × 2) = 4.

The cube root of 64 is 4.

Before solving the question, let's understand the concept of cube root.

The cube root of a number is the value obtained by multiplying it by itself three times or thrice. When we multiply 3 by itself three times, we get 3 x 3 x 3 = 27 = 3³, so the cube root of 27 is 3. Thus, we can say that the cube root gives a value that is basically cubed.

The cube root is denoted by

Now, we will find the cube root of 64.

Firstly, we have to find factor 64.

64 = 2 × 2 × 2 × 2 × 2 × 2.

64 = ∛4³

64 = 4

Therefore, the cube root of 64 is 4.

feet, where the sea turtle is located.

What was Leon's elevation after his second ascent?

Answers

Answer: -36 feet

Step-by-step explanation:

72-18 = 54 feet ascended

54 feet / 3 ascents = 18 feet per ascent

18 feet * 2 ascents = 36 feet

-72+ 36 = -36 feet

After his second ascent Leon was at an elevation is -36. Step by step; 72-18= 54

We can solve for H by isolating it on one side of the equation, as follows:

J/H - I/H = G

Taking H as the common denominator:

(J - I)/H = G

Multiplying both sides by H:

J - I = GH

Adding I to both sides:

J = GH + I

Dividing both sides by G:

H = (J - I)/G

So the answer is

(A)

H = (J - I)/G.

Answer:   A

Step-by-step explanation:

\(\frac{J}{H} = G + \frac{I}{H}\)                >Since you are solving for H bring I/H to the other side

                                   by subtracting I/H from both sides

\(\frac{J}{H}- \frac{I}{H} = G\)               >There is a common denominator so you can

Pairs (4) and (5) do not have corresponding products in the given options.

The products of the given pairs of numbers are:

(-5)(4.2) = -21

(-7)(-3) = 21

(4)(5) = 20

(2.5)(-9) = -22.5

So, the pairs of numbers and their products are as follows:

(-5)(4.2) = -21 matches with -21.

(-7)(-3) = 21 matches with 21.

(4)(5) = 20 matches with 20.

(2.5)(-9) = -22.5 matches with -22.5.
