seraphim [82]

Answer:

No mode

Median 7

Step-by-step explanation:

Mode: The mode is the element that occurs most in the data set. In this case, all elements occur only once, so there is no mode.

Median: Arrange the data in an ascending order and the median is the middle value. If the number of values is an even number, the median will be the average of the two middle numbers.

A stadium has two sections, A and B.
Alekssandra [29.7K]
ANSWER: a=12 b=15
Explanation: (look at work below)

4a + 1b = 63 (eq1)
5a + 3b = 105 (eq2)
-12a + -3b = -189 (subt. eq1 from eq2)
————————-
-7a = -84
a = 12
4(12) + 1b = 63 (plug in the a value)
48 + 1b = 63
b = 15

What is the surface area of this square pyramid?
Karo-lina-s [1.5K]

Answer:

A;3600 yd2

Step-by-step explanation:

The surface area is found by adding the area of the sides

The area of the bottom is

A= s^2 where s is the side length since it is a square

A = s^2 = 30^2= 900

We can find the area of one of the sides and multiply by 4 since all the sides are the same

The sides are triangles so

A = 1/2 bh  where b is the base b=30 and h is the height = 45

A = 1/2 (30)* 45

A = 675

We have 4 of these triangles

4*675 =2700

Add the 4 triangles and the bottom

2700+900

3600
