4. (5 x 3) x 2 = 5 x (3 x 2) is an example of which property?
A) Commutative Property for Addition
B) Associative Property for Multiplication
O C) Distributive Property for Multiplication
D) Commutative Property for Multiplication

Answers

Answer 1

Answer:

B, Associative property for multiplication

Step-by-step explanation:

Commutative property means the numbers can be multiplied in any order, so the (5 x 3) x 2 could be written as 3 x 5 x 2 and would be the same.

Associative property deals more with groupings of terms/numbers. Since the order of the numbers stayed the same, and the parentheses are moved, this is an example of the associative property.

Answer 2
The answer would be b

A severe storm has an average peak wave height of 16.4 feet for waves hitting the shore. Suppose that a storm is in progress with a severe storm class rating. Let us say that we want to set up a statistical test to see if the wave action (i.e., height) is dying down. The next 10 waves have an average wave height is 16 feet with a SD of .6 ft. If you wanted to test the hypothesis that the waves are dying down, what would you use for the alternate hypothesis

Answers

Answer:

The alternate hypothesis is:

[tex]H_{a} < 16[/tex]

Step-by-step explanation:

There are two types of hypothesis. The null hypothesis and the alternate hypothesis. The null hypothesis is that the mean found is equal to the expected value. The alternate hypothesis is a question about this expected value(different, more, less)

A severe storm has an average peak wave height of 16.4 feet for waves hitting the shore.

This means that the null hypothesis is [tex]H_{0} = 16.4[/tex]

Let us say that we want to set up a statistical test to see if the wave action (i.e., height) is dying down. If you wanted to test the hypothesis that the waves are dying down, what would you use for the alternate hypothesis

Dying down means lower average peak, that is, lower than the average of 16.4. This means that the alternate hypothesis is:

[tex]H_{a} < 16[/tex]

Answer: 5/12

Step-by-step explanation:

Answer:

5/12

Step-by-step explanation:

We are going to change both number so they have the same denominators.

1/4x3/3= 3/12

2/3x4/4=8/12

Once we changed the number we are going to subtract the numbers.

8/12-3/12=5/12

We can't simplify 5/12 so the answer is 5/12.

Answers

Answer:

Step-by-step explanation:

To find the number you have to reverse the equation

x + 9 = 13

So to find x we flip the equation

13 - 9 = x

Solve it

4 = x

So the missing number is 4

Step-by-step explanation:

So the little arrows on the lines means they are equal to each other so if you look, A to D and B to C have only one arrow meaning those two lines are the same lines

and A to B and D to C have two arrows meaning those two lines are the same

so that means if A to B is 9 and it's equal to the line D to C, then D to C is also 9

Hopefully this wasn't too confusing

Answer:

mCD = 9

Step-by-step explanation:

Because this polygon has opposite parallel sides, meaning each side across from each other are parallel, we know that this is a parallelogram. So:

AB ║ DC

BC ║ AD

Because this is a parallelogram, we know that, from the properties parallelograms, opposite sides of a parallelogram are congruent. This means that AB ≅ DC.

This also means that because AB = 9 and AB = DC, DC = 9.

Here's a mini two-column proof:

Statements     →     Reasons

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

mAB = 9     →     Given

AB ║ DC, BC ║ AD      →     Given

ABCD is a parallelogram      →     Definition of a Parallelogram

AB ≅ DC      →     Opposite sides of a parallelogram are congruent.

mAB = mDC      →     Definition of Congruent Segments

9 = mDC      →     Substitution Property of Equality

mCD = mDC      →     Reflexive Property of Equality

mCD = 9     →     Substitution Property of Equality

Step-by-step explanation:

10÷5/8=16

Answer:

Step-by-step explanation:

To solve problems where a fraction is being divided, we use a reciprocal of the fraction, which means that you flip the fraction upside down and multiply by the other number. So for this problem, the opposite of 5/8 is 8/5, so we need to multiply that by 10.

If you're not that familiar with these fractions and their equivalents, you can always compare them using their least common denominator: 24.

  Joseph: 1/3 = 8/24

  Anna: 1/6 = 4/24

  Elvin: 3/12 = 6/24

  Theo: 1/4 = 6/24

  Marina reached the greatest fraction of the goal.
