A ship takes 5 hours to sail 75 kilometres. What is its speed ?

Distance = 75 kilometres.

Time = 5 hours.

It's speed.

We know,

[tex] { \boxed{\bf{\rm \red {Speed \: = \frac{Distance}{Time}}}}} [/tex]

So, Speed = [tex] \bf \frac{75}{5} [/tex]

Speed = [tex] \bf 15 [/tex]

Step-by-step explanation:

[tex] \: \: here \: is \: your \: solution \\ \\ distance \: covered \: by \: ship \: = 75km \\ \\ time \: taken \: by \: by \: ship \: = 5hrs \\ \\ speed \: of \: ship = distance \div time \\ speed \: = 75/5 \\ \\ speed \: = 15km/hr \\ \\ hope \: it \: helps[/tex]

Answer:

4/6

Step-by-step explanation:

(1/6 times 4)make 4 into a fraction and that is 4/1  multyply the numerator and denominator 6x1=6 so 6 is the denominator and 4x1 is 4 so 4 is the numerator so its 4/6

The expression that represents the fraction is 1/6 * 1/4 or 1/24

The given parameters are:

Amount of candy = 1/6 pounds

Number of bags = 4

The expression that represents the amount in each bag is:

Amount = Amount of candy/Number of bags

This give

Amount = 1/6 / 4

Express as product

Amount = 1/6 * 1/4

Evaluate

Amount = 1/24

Hence, the expression that represents the fraction is 1/6 * 1/4 or 1/24

Answer:

The margin of error is of 0.11 carats.

The 95% confidence interval for the true mean weight of all sapphires produced by the new process is between 6.64 and 6.86 carats. The interpretation is that we are 95% sure that the true weight of all sapphires produced by the company using the new process is between these two values.

Step-by-step explanation:

We have the standard deviation for the sample, which means that we use the t-distribution to solve this question.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 37 - 1 = 36

95% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 36 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.05}{2} = 0.975[/tex]. So we have T = 2.0281

The margin of error is:

[tex]M = T\frac{s}{\sqrt{n}} = 2.0281\frac{0.33}{\sqrt{37}} = 0.11[/tex]

In which s is the standard deviation of the sample and n is the size of the sample.

The margin of error is of 0.11 carats.

The lower end of the interval is the sample mean subtracted by M. So it is 6.75 - 0.11 = 6.64 carats

The upper end of the interval is the sample mean added to M. So it is 6.75 + 0.11 = 6.86 carats.

The 95% confidence interval for the true mean weight of all sapphires produced by the new process is between 6.64 and 6.86 carats. The interpretation is that we are 95% sure that the true weight of all sapphires produced by the company using the new process is between these two values.

Answer:

72m^2

Step-by-step explanation:

first split the figure into 2 parts, the square and the triangle. The area of the sqaure is base times height or 6m times 10m which gives you 60m^2. For the triangle area you multiply base times height and divide it by 2, the base is 6m and the height is 4m so it will be 4x6 divided by 2 which gives you 12m^2. Lastly you add them both up, 60m^2 +12m^2 and you get 72m^2.

The improper fraction of the given mixed fraction is [tex]3\dfrac{1}{9}[/tex].

When the numerator exceeds or is equal to the denominator, the fraction is said to be inappropriate. 5/2 and 8/5, for instance, are incorrect fractions. The numerator and denominator are the two components of any fraction.

The given fraction is:

[tex]3\dfrac{1}{9}[/tex]

To convert this fraction into an improper fraction,

Multiply 3  with 9 then add it to the numerator,

[tex]\dfrac{3\times 9 + 1}{9} \\\\\dfrac{27 + 1}{9}\\\\ \dfrac{28}{9}[/tex]

Therefore,

[tex]3\dfrac{1}{9}[/tex] [tex]= \dfrac{28}{9}[/tex]

Hence,

The improper fraction of [tex]3\dfrac{1}{9}[/tex]  is [tex]\dfrac{28}{9}[/tex].
