Hi!
We can calculate this interval with the z-score of the 90% which is (by convention) 1.645
The interval is calculated as follows:
where x_m is the mean, σ the standar deviation and n is the number of samples:
replacing these values we get:
*rounded to the first decimal*
1.05 ± 0.05

Answer:
The correct option is D.
Step-by-step explanation:
Domain is the set of all posible
The volume of a rectangular prism is
where,
Dimensions can not be negative. So, the width and volume are always positive.
From the graph it is noticed that
In interval , width and volume is negative, so
interval is not the domain.
In interval (-5,0), width is negative, so (-5,0) interval is not the domain.
In interval (0,3), volume is negative, so (0,3) interval is not the domain.
In interval , width and volume is negative, so
interval is not the domain.
Therefore the correct option is D.
Answer:
0.0588 = 5.88% probability that a middle-aged man with diabetes is very active
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Has diabetes.
Event B: Is very active.
Probability of having diabetes:
To find this probability, we take in consideration that:
It also found that men who were very active (burning about 3,500 calories daily) were a fourth as likely to develop diabetes compared with men who were sedentary. Assume that one-fifth of all middle-aged men are very active, and the rest are classified as sedentary.
So the probability of developing diabetes is:
x of 4/5 = x of 0.8(not active)
x/4 = 0.25x of 1/5 = 0.2(very active). So
Probability of developing diabetes while being very active:
0.25x of 0.2. So
What is the probability that a middle-aged man with diabetes is very active?
0.0588 = 5.88% probability that a middle-aged man with diabetes is very active
Given, there are an average of 150 citizens eat daile in the cafeteria.
The average price of their meals = $5.95.
The discount given for sinior citizens in their meals = 20%
So we have to find 20% of $5.95 first.
20% of $5.95 =
=
=
=
So, the amount of discount given to the senior citizens = $1.19 per head.
As there are 150 cinior citizens daily.
So total discount given daily = $ =$
So we have got the required answer.
Option C is correct here.
