Write all number from least to greatest.

52 64 67 68 75 75 78 78 88 90

In the middle 75 and 75 were left. Median =(75+75)/2 = 75

Answer : 75.

To find the median of a data set order all the numbers from least to greatest, then find the number in the middle. If there are two numbers in the middle find the mean of the two numbers.

90 52 78 64 67 88 68 75 75 78 ← given

52 64 67 68 75 75 78 78 88 90 ← ordered l to g

75 and 75 are the two numbers in the middle, and since they are the same that means 75 is our median.

D) 75 is your answer.

3^3x+1= 81<br> Solve the exponential function

Reil [10]

Answer:

x=1

Step-by-step explanation:

3^ (3x+1) = 81

Rewrite 81 as a power of 3

3^4

3^ (3x+1) = 3^4

Since the bases are the same, the powers are the same

3x+1 =4

Subtract 1 from each side

3x+1-1 =4-1

3x=3

Divide by 3

3x/3 = 3/3

x =1

A skate board ramp is built on an incline so that it rests on a porch that is 1.3m high. The bottom of the ramp is placed 2.5m f

mr_godi [17]

Answer:

θ = 27.47°

Step-by-step explanation:

This problem can be represented as a right-angled triangle, as shown in the diagram below.

To find θ, we apply the tangent part of the trigonometric ratios SOHCAHTOA:

tanθ = $\frac{opposite}{adjacent}$

In the diagram, opposite = 1.3 m and adjacent = 2.5 m

Hence:

tanθ = $\frac{1.3}{2.5}$

tanθ = 0.52

θ = $tan^{-1} 0.52$

θ = 27.47°

The ramp forms 27.47° with the ground.
