Answer:

The median is equal 46.5

Step-by-step explanation:

to find the median, we will need to rearrange the numbers in ascending order, so we will have

43, 43, 43, 44, 44, 44, 45, 45, 45, 45, 45, 46, 46, 46, 47, 47, 49, 49, 49, 49, 49, 50, 50, 50, 51, 51, 51, 51

Note that there are 28 numbers in total, therefore the median will fall in between the fourteenth and the fifteenth number which are 46 and 47 respectively.

Since we are considering two figures as median, we will need to find the average, which will be

(46 + 47)/2 = 46.5

The median is therefore 46.5

The general term of an arithmetic sequence is tn = 32 + 3n, where n ∈N and n ≥ 1. The sequence is A) 32, 35, 38, 41, 44, 47,...

den301095 [7]

Answer:

35,38,41,44,47,50,....

Step-by-step explanation:

n ∈N means that n is an element of Natural numbers

Natural numbers are whole non-negative numbers

n ≥ 1, means that n = 1, 2, 3, 4, 5, 6,........

tn = 32 + 3n

the first term t1 = 32 + 3(1)

32 + 3 = 35

the second term t2 = 32 + 3(2)

32 + 6 = 38

the third term t3 = 32 + 3(3)

32 + 9 = 41

A monument in a park is shaped like a square pyramid. The dimensions are shown in the net. What is the surface area of the monum

vampirchik [111]

The surface area of the monument shaped like a square pyramid is 14 m².

Area is the amount of space that is occupied by a two dimensional shape or object.

From the diagram

Area of each triangle = (1/2) * base * height = (1/2) * 2 * 2.5 = 2.5 m²

Area of square = length * length = 2 m * 2 m = 4 m²

Surface area of monument = 4(2.5) + 4 = 14 m²

The surface area of the monument shaped like a square pyramid is 14 m².

Solve for g. 3/16 = (-5/4) + g

Ierofanga [76]

Answer:

g = 23/16

Step-by-step explanation:

3/16 = (-5/4) + g

Add 5/4 on both sides.

3/16 + 5/4 = g

Make denominators equal and add.

3/16 + 20/16 = g

23/16 = g

Solve for x. Write the smaller solution first, and the larger solution second. (x-10)^2-1=0

ikadub [295]

Answer:

$x_1 = 9$ and $x_2 = 11$ .

Step-by-step explanation:

Start by adding 1 to both sides of this equation.

$(x - 10)^{2} = 1$ .

The square of what number or numbers will lead to the number "1"? It turns out that not only $1^{2} = 1$ , but $(-1)^{2}= 1$ as well. In other words, the value $(x - 10)$ can be either 1 or -1. Either way, the equation is still going to hold. That's the reason why there are two solutions to this equation.
