Answer:
No unless x is being used to define only elements of an integer set.
Step-by-step explanation:
No, not in general unless x is defined as a integer or a subset of the integers like the naturals, whole numbers....
Usually 6<=x<=10 means all real numbers between 6 and 10, inclusive. This means example that 6.6 or 2pi are in this set with infinitely other numbers that I can't name.
{6,7,8,9,10} just means the set containing the numbers 6,7,8,9,10 and that's only those 5 numbers.
Answer:
1/2 or 0.5
Step-by-step explanation:
Answer: 0.74
Step-by-step explanation:
A= "The person is sick"
B= "The test gives a positive result"
P(A)=0.03
P(B|A)=0.92
P(B|A')=0.01
P(A')=1-P(A)=1-0.03=0.97
P(B)=P(B|A)P(A)+P(B|A')P(A')=0.92*0.03+0.01*0.97=0.0373
Based in Bayes Rule
P(A|B)=P(B|A)P(A)/P(B)=0.92*0.03/0.0373=0.74
Answer:
a. 20.5
Step-by-step explanation:
because this will form a right triangle we can use tan (opposite over adjacent) so an equation we could set up would be tan(70)=25/x
therefore we can just solve the equation which would give us 20.45. so if we round it the answer would be a
Answer:
The correct answer option is a. 20.5 feet.
Step-by-step explanation:
We are given that the angle of elevation of the ladder is 70° and the height of the ladder is 25 feet from the ground.
We are to find the distance of the building from the base of the ladder.
For this, we will use tan:
x = 20.5 feet
Answer:
99.85% of American women have shoe sizes that are less than 12.67
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 8.2
Standard deviation = 1.49
Using the empirical rule, what percentage of American women have shoe sizes that are less than 12.67
12.67 = 8.2 + 3*1.49
12.67 is 3 standard deviations above the mean.
Since the normal distribution is symmetric, 50% of the measures are below the mean and 50% are above. Of those 50% above, 99.7% are between the mean and 12.67. So
0.5 + 0.997*0.5 = 0.9985
99.85% of American women have shoe sizes that are less than 12.67
