Answer:

18/6=3

Step-by-step explanation:

Answer:

18/6 = 3

Step-by-step explanation:

Break it down.

(19-1) = 18

(3*2) = 6

So whats 18 divided by 6?

The subsets of {10, 19, 5, 0} are

{ } - the empty set, or 1 subset of size 0

{10}, {19}, {5}, {0} - 4 subsets of size 1

{10, 19}, {10, 5}, {10, 0}, {19, 5}, {19, 0}, {5, 0} - 6 subsets of size 2

{10, 19, 5}, {10, 19, 0}, {10, 5, 0}, {19, 5, 0} - 4 subsets of size 3

{10, 19, 5, 0} - 1 subset of size 4

A proper subset of a set is any subset of that set that is not equal to that set. The only subset that is not a proper subset is {10, 19, 5, 0}, since that's the set itself. So there are 15 proper subsets.

In general, a set of size n has a total of 2ⁿ subsets, and 2ⁿ - 1 proper subsets.

Answer:

x=-5

Step-by-step explanation:

-5*-3=15

15-2=13

Hope it helps

Answer:

x = -5

Step-by-step explanation:

-3x-2=13

Add 2 to both sides of the equation

-3x-2+2=13+2

Simplify

-3x=15

Divide both sides of the equation by the same term

[tex]\frac{-3x}{3} =\frac{15}{-3}[/tex]

Simplify

x = -5

Probability of not raining and the flight leaving on time is equals to 0.320 .

De Morgan's law

P( A'∩ B')  = P (A∪B)'

P (A∪B)' = 1 -  P (A∪B)

P(A∪B) = P(A) + P(B) - P(A∩B)

According to the question,

Let Probability of rain = P(A)

                                    = 0.07

Probability of flight delay =P(B) = 0.12

Therefore ,

Probability of rain and flight delay = P (A∩B)

                                                         = 0.87

Probability of not raining and flight on time = P( A'∩ B')

Substitute the values in the formula

P( A'∩ B') = 1 - [ 0.07 + 0.12 -0.87]

               = 1- 0.68

               = 0.32

               = 0.320 ( nearest thousandth)

Answer:

it depends on how big the rectangle is though...

Step-by-step explanation:

Answer:

6x + 10

Step-by-step explanation:

Given,

Length ( l ) = 3x

Breadth ( b ) = 5

To find : Perimeter of the rectangle = ?

Formula : -

Perimeter of the rectangle = 2 ( l + b )

Perimeter of the rectangle

= 2 ( 3x + 5 )

= 2 ( 3x ) + 2 ( 5 )

= 6x + 10

Answer:

true

Step-by-step explanation:

please mark brainiest

96 divided by 2 = 48

96 divided by 3 = 32

96 divided by 4 = 24

96 divided by 6 = 16

96 divided by 8 = 12

96 divided by 12 = 8

96 divided by 16 = 6

96 divided by 24 = 4

96 divided by 32 = 3

96 divided by 48 = 2

Answer:

45 girls

Step-by-step explanation:

There is 4 more boys than girls in each ratio.

60 boys / 4 = 15 groups where there is more boys

3 (girls) x 15 groups = 45 girls in total

Answer:

m < U = 65°

Step-by-step explanation:

Given that m < PTU° = 115°, and that it is a supplement to < UTV, then we can establish that m < UTV = 65° because their angles must add up to 180°.

From this point forward, we'll name < UTV as < T of △VUT.

Now that we have the measure of < T, we can find out the value of the missing angle, < VUT, through the following equation:

180° = m < V° + m < T° + m < U°

180° =  m < 50° + m < 65° +  x

180° =  m < 115° +  x

Subtract m < 115 from both sides to isolate x:

180° -  m < 115° =  m < 115° - m < 115° +  x

65° = x

To verify that we have the correct answer, we'll add up all the measures of the three angles of the triangle to see if it sums up to 180°:

180° = m < V° + m < T° + m < U°

180° = m < 50° + m < 65° + m < 65°

180° = m < 50° + m < 65° + m < 65°

180°  = 180°  (True statement).

Therefore, the measure of the missing angle, < U = 65°
