Answer:
Step-by-step explanation:
<u>The ratio of sides in 30º-60º-90º triangle is:</u>
<u>If a is 5√3, the length of b is:</u>
- b = a√3 = 5√3 *√3 = 5*3 = 15
Answer:
x = 44
Step-by-step explanation:
3x - 5 is complementary to y° so their sum is 180°
The angle with measure 127° is also complementary with y°
127 + y = 180
y = 53°
53 + 3x - 5 = 180
3x + 48 = 180
3x = 132
x = 44
Mean = $52
median = $53
no mode
range = 63 - 40 = $23
The reason why Fiona cannot make a valid prediction based on the mean of the population is that the variation of Fiona’s samples is too large.
<h3>Why can't Fiona use the means she recorded?</h3><h3 />
Mean is quite sensitive to outliers so it is best used when the variation between variables is not too much.
In Fiona's case, there variation is quite high with high variable of 95 compared to a low value of 45.
