Which of the following shows the Commutative Property of Multiplication?



(3 × 2) × 7 = 3 × (2 × 7)

4 × (5 + 8) = (4 × 5) + (4 × 8)

4 × 5 = 5 × 4

9 × 7 = 63

Answers

Answer:

The options that show the Commutative Property of Multiplication are:

A) 4x5=5x4

C) (3 x 2) × 7 = 3 ×(2 x 7)  

------------------------------

The commutative property of multiplication states that the order in which the factors are multiplied does not change the product, that is:

Of the options, the ones which show it are:

A) 4x5=5x4

C) (3 x 2) × 7 = 3 ×(2 x 7)

In C), on the left side, the first 3 is multiplied by 2, then the result 6 is multiplied by 7, resulting in 42. On the right side, 2 is multiplied by 7, resulting in 14, which is multiplied by 3, resulting in 42.

You have a bag of gummy worms with 5 green, 3 blue, 6 red, and 2 orange. Which expression represents the probability that you will reach into the bag and pull a red worm, eat it, and then pull a green worm?​

Answers

Answer:

[tex]\frac{1}{8}[/tex] I think

Step-by-step explanation:

you have a bag witha a total of 16 gummy worms right? 6 out of 16 of them are red, 5 out of 16 are green.

so you pull out a red one and eat it. the probabilty of you doing that is [tex]\frac{6}{16}[/tex] . keep it in mind that you ate a gummy worm.after enjoying that gummy worm you decide to take another one, but this time, it's green. you know you just ate one right, but you did not replace it now did you? what that means is out of the 16 gummies you had, you are now left with 15 (because you ate one).now you are left with 15 gummy worms. you take a green one out of the packet. the probabilty of you doing that is [tex]\frac{5}{15}[/tex].

now that you've got your probabilities all sorted, now it's time to use some basic probability principles. if you ever come across a probability question with the word and, you need to know automatically that you are multiplying. if you ever come across the word or, you are adding. it's always gonna be like this.

so when you multiply your two probabilities, you get the answer [tex]\frac{1}{8}[/tex]

whenever you're dealing with probability, make sure you're aware of things that are being taken. check whether they're being replaced or not. the way I attempted at working it out is how the other probability questions involving replacements are solved, no matter what it is.

I really hope you found this helpful (that is if all I said is correct) :)

MR X was at the crown of the statue of liberty in an island of New York City. He sighted a cargo ship coming into New York harbor with an angle of depression 35 degree. How far is the cargo ship from the base of the statue of liberty

Answers

Answer:

d = h/1.43

Step-by-step explanation:

Given

Angle of depression = 35°

To Find

Distance between cargo ship and base of The Statue of Liberty

Solving

Let the height of the statue be 'h' and distance between it and the ship be 'd'Upon changing the viewpoint (you'll see why) to the ship viewing the top of the statue, the angle is now (90 - 35)° = 55°Then, upon taking the tan ratio of the angle between them :

⇒ tan 55° = h/d

⇒ 1.43 (approx.) = h/d

d = h/1.43

[∴ Input the value of height in this formula if it is given, and you should be able to get your answer.]

Choose which statements are true:

I. Every parallelogram is a rhombus.

II. Every rhombus is a parallelogram.

III. Every quadrilateral has 4 sides.

Answers

Answer:

II. Every rhombus is a parallelogram.

III. Every quadrilateral has 4 sides.

Step-by-step explanation:

        Not all parallelograms are rhombuses because a rhombus needs to have equal sides, but a parallelogram does not.

        The definition of a rhombus is "a parallelogram with opposite equal acute angles, opposite equal obtuse angles, and four equal sides" so all rhombuses are parallelograms.

        The definition of a quadrilateral is having four sides, so all quadrilaterals will have four sides.

From the complete question, Roberto correctly sees that y cannot be equal to both 10 more than three times a number and 2 less than three times a number at the same time.

Delmar correctly concludes that because 3x + 10 and 3x - 2 will never be equal, the system has zero solution.
