Answer:

see image

Step-by-step explanation:

use a ruler and a "set square", a tool to make a neat 90° angle. See image.

Point R can be anywhere as long as it is not on PQ. PQ can be at any angle or any length. There are many, many ways to follow these directions. The idea maybe be to practice using the tools or the idea may be that for any segment and point not on the segment, there exists a way to drop a perpendicular from the point to the segment.

According to the hypothesis test, the option that gives the most appropriate method for creating such an estimate is:

A one-sample z-interval for a population proportion.

He will test if there is enough support to build a new middle school, that is, if the population proportion that supports the building of a new middle school is greater than a threshold.

Only one sample is taken from the district residents, hence the correct option is:

A one-sample z-interval for a population proportion.

The distance between her house and the school is 1800 meters.

We must use the relation:

distance = speed*time

Here we have:

We should rewrite the time into seconds, then we have:

15 minutes = 15*(60 seconds) = 900s

Then the distance is:

distance = (2m/s)*(900s) = 1800m

Hey ! there

Answer:

Step-by-step explanation:

In the question we're given that Salima takes 15 minutes from her house to reach her school on a bicycle and bicycle has speed of 2m/s .

And we are asked to calculate the distance between her house and the school .So for finding the distance we need to know the speed formula that is ,

[tex] \: \qquad \: \qquad \: \red{\underline{\red{\boxed{\frak{Speed = \frac{Distance}{Time}}}}}} [/tex]

So ,

[tex] \:\qquad \quad \underline{\boxed{ \frak{Distance = Speed \times Time} } }[/tex]✦

As it's given in the question that the speed of bicycle is 2 m/s and she takes 15 minutes to reach the school . So , for finding distance we must have to convert 15 minutes into seconds .

We know that ,

Therefore in 15 minutes we have ,

Now Solving : -

[tex] \longmapsto \: \qquad \: \sf{Distance =2 \times 900}[/tex]

By , multiplying 2 and 900 , We get :

[tex] \longmapsto \: \qquad \: \purple{\underline{\purple{\boxed{\frak{ {Distance = 1800 \: m}}}}}}[/tex]

The answer is the last one.

Step-by-step explanation:

They paid $24.10 dollars, they paid $1.25 each and they paid $2.70 per mile. So, we subtract 2.50 from 24.10, since Landis and her father went together. And then, we divide our answer by 2.70.

24.10 - 2.50 = 21.60

21.60/2.70 = 8

Using the combination formula, it is found that 120 distributions are possible.

In this problem, the order in which the items are distributed is not important, hence the combination formula is used to solve this question.

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by:

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

In this problem, 7 items will be given to a set of 10 people, hence:

[tex]C_{10,7} = \frac{10!}{7!3!} = 120[/tex]

120 distributions are possible.

Step-by-step explanation:

The first thing to do is calculate The weight of a 10 quarts of milk.

The area of a shape is the amount of space on the shape

The approximate area of the circle is 27.52 square units

The given parameters are:

Sectors = 16

Base = 1.17 units

Height = 2.94 units

The area of the triangle is:

[tex]A_1 = 0.5 * Base * Height[/tex]

So, we have:

[tex]A_1 = 0.5 * 1.17 * 2.94[/tex]

[tex]A_1 = 1.7199[/tex]

The approximate area of the circle is then calculated as:

[tex]A_2 = 16 * A_1[/tex]

This gives

[tex]A_2 = 16 * 1.7199[/tex]

[tex]A_2 = 27.52[/tex]

Hence, the approximate area of the circle is 27.52 square units

Answer:

27.52

Step-by-step explanation:

A = 1/2 bh

fill in the given information

A = 1/2 (1.17)(2.94)

multiply 1.17 and 2.94

A = 1/2 (3.4398)

Mutiply 3.4389 by 1/2 or divide 3.4398 by 2 (it is the same thing)

A = 1.7199

Now you have the area of one of the triangles, so you have to find the area of the whole circle or 16 triangles.

A = 1.7199 (16)

Mutpily

A = 27.5185

round to the nearest hunderth

A = 27.52
