All of the statements has the qualifier "can be".
This means that we need just one single in each example to make the statement true.
In an equilateral triangle, medians, angle bisectors, altitudes and perpendicular bisectors are all coincident, which makes the first three statements true. This in turn makes the fourth statement true.
So there are no false statements.
Answer:
0.006 is the probability that the record will be broken in next year.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 62 seconds
Standard Deviation, σ = 0.8 seconds
We are given that the distribution of face time is a bell shaped distribution that is a normal distribution.
Formula:
The record will be broken if the time is less than 60 seconds.
P(time is less than 60 seconds)
P(x < 60)
Calculation the value from standard normal z table, we have,
Thus, 0.006 is the probability that the record will be broken in next year.
Answer:
B
Step-by-step explanation:
I believe the answer is B because if we multiply the top equation by 6, we get 48x + 30y = -42, and if we multiply the bottom equation by -5, we get
35x - 30y = 20. So now, if we add it all together, then the positive 30y and negative 30y cancel out aka it equals 0, and thus the variable y is gone, satisfying the requirement that the problem asks for ("Which of these strategies would eliminate a variable...").
I hope this helped, and if it's correct, I'd appreciate if you marked my answer as Brainliest :)
Answer:
5/18
Step-by-step explanation:
The LCD of 9, 3, and 6 is 18.
1 - 2/9 - 1/3 - 1/6 =
= 18/18 - 4/18 - 6/18 - 3/18
= 5/18
Answer:
y=12x-50
Step-by-step explanation:
Distribute 12, x, and 4
y+2=12(x-4)
1. y+2=12x-48
Subtract 2 from both sides
2. y=12x-50
