Esmeralda I think it's wrong cuz it’s like the question but that's added a parentheses so I think that's wrong
Answer:
∠B = 12°
∠C = 180 - 48° = 132° ( straight line angle = 180)
Sum of angles of a triangle = 180°
180 = ∠A + ∠B + ∠C
180 = ∠A + 12 + 132
180 - 144 = ∠A
∠A = 36°
option B
3/4
Three fourths subtracted from one half is one fourth. One fourth times one half is one eighth.
Answer:
1.01
Step-by-step explanation:
Mean with outliner = (39.55 + 40.51 + 41.01 + 37.76+ 35.32 + 33.28 + 34.38 + 36.48 + 39.87 + 50.32 + 40.59 + 41.71)/12 = 39.23 seconds.
In this case, the outlier comes to be the data: 50.32. If we don't consider that data point, the mean equals:
Mean wihout outliner = (39.55 + 40.51 + 41.01 + 37.76+ 35.32 + 33.28 + 34.38 + 36.48 + 39.87 + 40.59 + 41.71)/11 = 38.22
The difference is: 39.23 - 38.22 = 1.01
