Find the median of :

Mathematics
2 answers:
dusya [7]3 years ago

Answer: 28.

Step-by-step explanation:

The median of a data set is defined as the middle value of a data set.

For instance, the median of the data set [4, 7, 8] would be 7 because it is the "middle value".

You can find this by sorting the numbers by smallest to largest:

2, 9, 15, 16, 21, 24, 28, 32, 34, 35, 37, 39, 40

There are 13 numbers in the set, so you can exclude the first 6 and last 6 numbers from the set to get your median, 28.

Answer:

Median = 28.

Step-by-step explanation:

First arrange the list in ascending order:

2  9  15  16  21  24  28  32  34  35  37  39  40

The median is the middle number,

There are 13 numbers so the middle number is the 7th - that is 28.

Simplify 4( 3+ 7y) + 6(2 - y) if y =2
UkoKoshka [18]

Answer:

68

Step-by-step explanation:

The expression is given as:

4( 3+ 7y) + 6(2 - y)

It is known that y is equal to 2. Therefore, substitute 2 in for y.

4(3+7(2))+6(2-2)

Now, solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction

Solve inside of the parentheses first.

4(3+7(2))+6(2-2)

4(3+14)+6(0)

4(17)+6(0)

Multiply

68+0

Add

68

I WILL MARK YOU BRAINLIEST!PLEASE SOLVE FOR X
polet [3.4K]

Answer and Step-by-step explanation:

We see that the bottom two lines are parallel, which makes angle x and angle 5 "same-side corresponding angles". By definition, same-side corresponding angles are congruent. That means angle x = angle 5.

Note that you didn't provide any measures, so it is impossible to actually figure out an exact degree. However, angle x is the same degree as angle 5.

Hope this helps!

List all partitions of the set. (a) (1,2) (b) [a, b,c)
Alchen [17]

Answer: Hello mate!

The partition of a set is defined as a partition of the set into a nonempty subset, where the set itself is a subset of himself, then the set is a partition of himself.

a) in this we have a set of two objects; A = (1,2) the partitions of this set are: (∅), (1), (2) and (1,2). Where (∅) is the null set.

b) Now we have a set of three objects; B = (a,b,c) the partitions of this set are: (∅), (a), (b), (c), (a,b), (a,c), (b,c), (a,b,c)

Luiza is jumping on a trampoline. Ht models her distance above the ground (in m) t seconds after she starts
Damm [24]

Answer:

t=2.08 seconds.

Step-by-step explanation:

Well, in this example, H(t)=-0.6cos(2pi/2.5)t+1.5 should be equal to 1.2. If calculated, -0.6cos(0.8pi)t=1.2-1.5 which is equal to -0.6cos(0.8pi)t=-0.3, then cos(0.8pi)t=0.5. The value of cosine in terms of radians when it is equal to 0.5 is pi/3. So, cos(0.8pi)t=cos(pi/3). If simplified, (0.8pi)*t=5pi/3. pi's are cancelled out and t is calculated as 2.08333... If rounded to the nearest hundredth it is 2.08.
