Answer:
x is 5
ST is 45
Step-by-step explanation:
In the given figure
∵ m is the bisector of the segment SU
→ That means m intersects SU at the midpoint of SU
∵ m ∩ SU at point T
∴ T is the midpoint of SU
→ The midpoint of a segment divides it into two equal parts
∵ The point T divides SU to ST and TU
∴ ST = TU
∵ ST = 9x
∵ TU = 4x + 25
→ Equate them
∴ 9x = 4x + 25
→ Subtract 4x from both sides
∵ 9x - 4x = 4x - 4x + 25
∴ 5x = 25
→ Divide both sides by 5
∴ x = 5
→ Substitute the value of x in ST
∵ ST = 9(5) = 45
∴ ST is 45
Answer:
Option C is correct.
f = 2
Step-by-step explanation:
The mean is the sum of variables divided by the number of variables
Mean = (Σfx)/(Σf)
xi | 15 | 17 | 20 | 30 | 10 + f
fi | 4 | 4 | 6 | 5 | 6
Σfx = (15×4) + (17×4) + (20×6) + (30×5) + [(10+f)×6] = 60 + 68 + 120 + 150 + 60 + 6f = (458 + 6f)
Σf = 4 + 4 + 6 + 5 + 6 = 25
Mean = 18.8
18.8 = (458+6f) ÷ 25
458 + 6f = 25 × 18.8 = 470
6f = 470 - 458 = 12
f = (12/6) = 2

Hey there!
Assuming that all the sections are the same size, there are four sections of equal size.
Blue would be one out of those four sections, so the probability is 1/4. In decimal form this is .25, and as a percent this is 25%.
Hope this helps!
Hi.
Please note that I haven't done much algebra.
4 more = 4 +
Twice as many than the runner up means 2 times the amount they ate (a variable) = 2n
So far we have 4 + 2n
Since it's an equation, we are going to know what it equals. In the problem, we find out that it's 11. So the equation looks like this:
4 + 2n = 11
If this didn't work out, please let me know.
