Answer:
The probability is 2.2%
Step-by-step explanation:
The probability that a randomly selected adult uses the telephone in classes is always equal to 0.48.
If x represents the number of adults selected from among the 8 that the telephone uses in classes, then x is a discrete random variable that follows a binomial distribution, with:
p = 0.48
q = 0.52
n = 8
We want to find the probability of x = 5
The probability is 2.2%
Answer:
2. y = 7
3. x = 4
Step-by-step explanation:
Slope 0 is when the line is horizontal.. has a constant coordinate
(-5,7) lies on the line so the x-coordinate is 7
Equation: y = 7
A vertical line has all same x-coordinates.
Since (4,-2) is on the line, every point had x-coordinate of 4.
Equation: x = 5
Answer:
C) 56
Step-by-step explanation:
DEG and FEG are on a straight line forming 180 degree.
Set your formula up as
180 = (3x+31)+(2x-6)
180 = 3x +2x +31 - 6
180 - 31 + 6 = 5x
155 = 5x
155/5 = x
31 = x
Now substitute 31 in place of x
FEG = (2*31-6)
FEG = 56
Answer:
1.
25 of the 36 collars will be accepted. I just counted the numbers that were either "14" "15" or "16" because the company will only accept the collars that have 14-16 miligrams of medicine in them.
2. I expect the company to reject 11 of them because 25-36 = 11
