Answer:
Standard deviation of the population is 2.4
Step-by-step explanation:
Finishing times of 6 participants in 200 meter dash has been given as 27, 28, 27, 25, 24, 31.
We have to calculate the standard deviation of the population formed by these timings.
Formula of standard deviation is
where = standard deviation
= mean of the data
n = number of scores in the sample
Mean of given data =
=
= 30
Now
= 2.236 ≈ 2.24
Therefore, standard deviation of the given data is 2.24
Answer:
1 1/5 per person.
Step-by-step explanation:
You have to evenly divide the 6 funnel cakes among 5 people, so the equation you have to use is division.
5/6
= 1 1/5
Answer:
Step-by-step explanation:
→ We know that co-interior angles add up to 180°, so we can set up an equation
x + 17 + 4x + 3 = 180
→ Collect the x terms
5x + 17 + 3 = 180
→ Collect the integers
5x + 20 = 180
→ Minus 20 from both sides to isolate 5x
5x = 160
→ Divide both sides by 5 to isolate x
x = 32
⇒ Now we know the value of x, we can substitute it in back into m∠f because we know angles on a straight line add up to 180°
4x + 3 when x = 32 ⇔ 4 × 32 + 3 ⇔ 128 + 3 ⇔ 131
