Answer:
42:42
Step-by-step explanation:
42:42 is simplified to 6:7
Answer: The probability that none of the calls would result in a reservation would be 0.72%.
Since there is an 18% chance that there would be a reservation, then there is a 72% chance that there is not a reservation.
Our goal is to determine the likelihood that there are no calls. Or that the 72% chance event happens 15 times.
We can use the following expression to find that repeated probability.
(0.72)^15 = 0.0072 or 0.72%
Step-by-step explanation:
The plumber's daily earnings have a mean of $145 per day with a standard deviation of
$16.50.
We want to find the probability that the plumber earns between $135 and
$175 on a given day, if the daily earnings follow a normal distribution.
That is we want to find P(135 <X<175).
Let us convert to z-scores using
This means that:
We simplify to get:
From the standard n normal distribution table,
P(z<1.82)=0.9656
P(z<-0.61)=0.2709
To find the area between the two z-scores, we subtract to obtain:
P(-0.61<z<1.82)=0.9656-0.2709=0.6947
This means that:
The correct choice is C.
Answer:
Now if we increase the radius by a factor of 2 the new volume would be:
And we can find the increase factor for the volume like this:
Then if we increase the radius by 2 the volume increase by a factor of 4
If we reduce the radius by a factor of 2 then we will have that the volume would be reduced by a factor of 4.
On the figure attached we have an illustration for the cases analyzed we see that when we increase the radius the volume increase and in the other case decrease.
Step-by-step explanation:
For this case we have the following info given:
and we can find the initial volume:
And replacing we got:
Now if we increase the radius by a factor of 2 the new volume would be:
And we can find the increase factor for the volume like this:
Then if we increase the radius by 2 the volume increase by a factor of 4
If we reduce the radius by a factor of 2 then we will have that the volume would be reduced by a factor of 4.
On the figure attached we have an illustration for the cases analyzed we see that when we increase the radius the volume increase and in the other case decrease.
