How far, D, does a vehicle travel if it is moving at a rate, r, of 60 km/h and it travels for t =150 minutes? Use the formula D=rt.

The distance of a vehicle travel is 150 km, at a moving rate of 60 km/h for 150 minutes.

Step-by-step explanation:

            The given is,

                   Moving rate, r = 60 km/h

                   Time, t = 150 minutes

Step:1

            We need to find the distance traveled by the vehicle,

            From given the formula is

                        D = rt

            Where,

                D = Distance in Km

                 r = Moving rate in Km/h

                 t = Time in hours

Step:2

         We need to convert the time minutes to hours

                   t = hours

                   t = 2.5 hours

Step:3

        Distance traveled by the vehicle is,

                D = 60 × 2.5

                    = 150

                D = 150 Km

Result:

      The distance traveled by the vehicle is 150 Km at a moving rate of 60 km/h for 150 minutes.

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;

answer: y = 3/2 x - 3

y = 1/8 x - 3/4 that would be your correct option
