Z = (score - mean)/sd

-1.75 = (x - 38)/4

Multiply both sides by 4:

-7 = x -38

Add 38 to both sides:

x = 31

He scored a 31 points on the exam

What is measurement angle C?<br>​
11Alexandr11 [23.1K]
So you know all angles in a triangle add to 180 degrees and you have x + 3x + 2x which adds to 6x so you do 180/6 to get x = 30 and c = 2x so you do 30 x 2 which is 60 degrees. Hope this helps :)

Find the mean, median, mode, and range of this data: 49, 49, 54, 55, 52, 49, 55. If necessary, round to the nearest tenth.
krok68 [10]

Answer:

Mean = 51.4.

Mode = 49.

Median = 52.

Range = 6.

Step-by-step explanation:

Mean = Sum of all observations / Number of observations.

Mean = (49+49+54+55+52+49+52)/7

Mean = 360/7

Mean = 51.4 (to the nearest tenth).

Mode = The most repeated values = 49 (repeated 3 times).

Range = Largest Value - Smallest Value = 55 - 49 = 6.

Median = The central value of the data.

First, arrange the data in the ascending order: 49, 49, 49, 52, 54, 55, 55.

It can be seen that the middle value is 52. Therefore, median = 52!!!
