Answer: 1/3

Step-by-step explanation:

From the question, we are informed that there is a cube with sides numbered 1 through 6.

The probability of rolling a 3 or 4 means that we can get 2 numbers out of possible 6. Therefore, the probability will be:

= 2/6

= 1/3

Answer:

Option c, d and e are equivalent expressions to 7x-14

Step-by-step explanation:

Which expressions are equivalent to 7x - 14

Equivalent Expressions:

The expressions that are the same, even if the expression looks different.

For example: 2x^2+4 is equivalent to 2(x^2+2) because solving 2(x^2+2) we get 2x^2+4

Now, finding equivalent to expressions 7x - 14

Option a) 14 - 7x

Not equivalent to 7x-14

Option b) x-2

Not equivalent to 7x-14

Option c) -(14 – 7x)

Simplifying: -14+7x so, equivalent to 7x-14

Option d) (x - 2)

Simplifying: 7x-14 so, equivalent to 7x-14

Option e) - 14 + 4x

Simplifying: 3x+4x-14 = 7x-14, so, equivalent to 7x-14

Option f) 2x - 10 + 5x + 4

Simplifying: 2x+5x-10+4 = 7x-6 so, Not equivalent to 7x-14

So, Option c, d and e are equivalent expressions to 7x-14

Answer:

3

Step-by-step explanation:

because if N = 6, then you will have to substitute the n to n and then do the order of operation. first it will be 6+3=9 and then 9*5=45. then you will do 7*6=42 and then subtract 45-42=3

Answer:

3

Step-by-step explanation:

Okay, since we know what n equals to, all we have to do is insert 6 where n was:

[tex]5(6+3)-7(6)[/tex]

Now we just need to simplify, so:

[tex]30 + 15 - 42[/tex]

[tex]45-42[/tex]

And we get our answer

[tex]= 3[/tex]

Answer:

An obtuse triangle has one angle larger than 90 degrees (deg). Given information, the two base angles EDF and EFD are represented by one variable x, therefore they are equal.

The sum of all angles of any triangle is 180 deg so angles EDF + EFD + DEF = 180 deg

Since the obtuse angle must be larger than 90 deg, the sum of the other two angles must be less than 90.

Angles EDF + EFD < 90 and 90 < DEF can be re written

An inequality of angles EDF + EFD < DEF

Since angles EDF and EFD are equal to x their sum is (x + x) or 2x, so we can write

2x < 90 divide both sides by 2

{0 < x < 45} is all possible values of x.

A function can be written to represent this. The function will accept input of the obtuse angle and output the two equal acute angles.

F(x) = (180 - x) / 2

where x is the measure of the obtuse angle. Only works for symmetric triangle. F(x) is the measure of each of the other two angles.

likely nor unlikely

Step-by-step explanation:

carlos can pivk any

It is likely for Carlos to randomly select a brown block, but unlikely for him to randomly select a yellow or orange block.

A permutation is an orderly arrangement of things or numbers. Combinations are a means to choose items or numbers from a collection or set of items without worrying about the items' chronological order.

For each color, we can determine the probability of selecting that color by dividing the number of blocks of that color by the total number of blocks in the box:

Brown: 48 blocks out of 53 total blocks = 48/53

≈ 0.91, which is Likely.

Yellow: 3 blocks out of 53 total blocks = 3/53

≈ 0.06, which is Unlikely.

Orange: 2 blocks out of 53 total blocks = 2/53

≈ 0.04, which is Unlikely.

Therefore, it is likely for Carlos to randomly select a brown block, but unlikely for him to randomly select a yellow or orange block.
