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.

Answer:

x = 10

Step-by-step explanation:

3x + 38 = 7x - 2

subtract 3x from both sides ogf the equation:

38 = 4x - 2

add 2 to each side:

40 = 4x

divide both sides by 4:

x = 10

Answer:

6/8 and 9/12

Step-by-step explanation:

You can find any by multiplying numerator and denominator by any given number. The number multiplied has to be the same for the top and the bottom

1. Number is 2

3/4 * 2/2 = 6/8 (3*2 = 6  and 4*2 = 8)

2. Number is 3

3/4*3/3 = 9/12 (3*3 = 9 and 3*4 = 12)

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:

weight of raisins : 40

Step-by-step explanation:

nuts : raisins : oats

3:2:5= 60: ? : ?

60÷3 = 20

raisins : 2×20 = 40

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:24

Step-by-step explanation: 4x3x2x1

The product of a whole number 'n' with every whole number until 1 is called the factorial. The number of ways the lawyer can meet the client is 24 or 4!.

The product of a whole number 'n' with every whole number until 1 is called the factorial. The factorial of 4 is, for example, 43221, which equals 24.

A lawyer has 4 clients to meet. The number of ways the lawyer can meet the client is 4!.

Number of ways = 4! = 4×3×2×1 = 24

Hence, the number of ways the lawyer can meet the client is 24 or 4!.
