The launch time is 11: 20 and a rocket is scheduled to launch from a command center in 3.75 how what time is it now?

To solve this problem, let us first make sure that the values are in similar format. So to make the two values in same format, let us first convert the launch time which is in clock time format into decimal form.

The given launch time is 11:20 which reads as 11 hour 20 minutes. Since there are 60 minutes in an hour, therefore:

20 minutes (1 hour / 60 minutes) = 0.33 hour

Therefore the launch time in decimal form is 11.33

Now we can subtract the value of 3.75 to know the time now:

time now = 11.33 – 3.75

time now = 7.58

Rewriting this in terms of clock format:

0.58 hour (60 minutes / hour) = 35 minutes

Therefore the time now is:

7:35

step-by-step explanation:

i have done this all on a piece of paper but idk how to put it on here cuz it needs to be drawn

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
