Answer:
All real numbers or negative infinity to positive infinity in set notation.
Step-by-step explanation:
Answer:
x-intercept= (5,0)
y-intercept= (0,-2)
Slope= 2/5
Step-by-step explanation:
<span>Given that 35% of the tracks are curved, this means that 100% - 35% = 65% of the tracks are straight.
Therefore, the fraction of the tracks that are straight is given by
![\frac{65}{100} = \frac{13}{20}](https://tex.z-dn.net/?f=%20%5Cfrac%7B65%7D%7B100%7D%20%3D%20%5Cfrac%7B13%7D%7B20%7D%20)

Answer:
Y= -8.4 , slope is 0, y-intercept is -8.4
Step-by-step explanation:
divide both sides by 5, to get y by itself. you are left with y= -8.4. as you can see, there is no x so there is no slope. and y, which is the y variable is equal to -8.4 as shown in the answer. hope that helped
The mean is 30, median is 26.875 and mode is 28.19.
<h3>What is Mean?</h3>
The mean for a given set of observations is equal to the sum of all the values of a collection of data divided by the total number of values in the data.
Here, given data:
Class Interval frequency(f) mid value(x) xf
16 - 20 2 18 36
21 - 25 7 23 161
26 - 30 14 28 392
31 - 35 8 33 264
36 - 40 8 38 304
41 - 45 1 43 43
Mean = ∑xf / ∑f
= 1200 / 40
= 30
Median = l + {(n/2)-c}/f X h
= 25.5 + (20-9)X5/40
= 25.5 + 55/40
= 25.5 + 1.375
= 26.875
Mode = l + (f₀-f₁)/ (2f₀-f₁-f₂)Xh
= 25.5 + (14-7)/ (2X 14 - 7 - 8) X 5
= 25.5 + 7/13 X 5
= 25.5 + 35/13
= 25.5 + 2.692
= 28.19
Thus, the mean is 30, median is 26.875 and mode is 28.19.
