i think this is the answer

Option - D - Image 3and 4 is correct

We have the following images.

We have to classify which image is a tessellations.

tessellations is also called tiling which involves the covering up of rigid plane surface using the geometric shapes (tiles) ensuring that these shapes don't overlap and leave no gap.

In the image 3, we have a geometric shape called triangle which is used as a tile to cover the surface. These shapes don't overlap and leave no gap as they perfectly fit with one another. Similar is the case with image 4, where hexagonal tiles are used. Therefore, image 3 and 4 are tessellations. The images 1 and 2 does not have any predefined geometric shape and nothing can be said about their perfect fit. Hence these are not tessellations.

Hence, Option - D is correct.

Since the lines are parallel they have the same slope 2/3. use point slope form to get,

y+2=2/3(x-1)

y+2=2/3x-2/3

y=2/3x-8/3

3y=2x-8

Answer:

S=R

75+75=150

360-150=210

210/2=105

y=105

Answer:

y = 105°

Step-by-step explanation:

In an isosceles trapezoid.

Any lower base angle is supplementary to any upper base angle, that is

y = 180° - 75° = 105°

Step-by-step explanation:

x+85+x+44+63=180(sum of angles of a triangle)

or,2x+192=180

or,2x=180-192

or,x=-12

Angle A=x+44

=-12+44

=32°

Because it contains the points (0, 0) and (pi/2, 1), the first graph is the graph of sin(x).

To identify the graph of sin(x), we need to remember some points of the sine function.

We know that sin(0) = 0, this means that this passes through the point (0, 0).

And we also know that sin(pi/2) = 1, then it also passes through the point (pi/2, 1).

With that in mind, the graph that passes through those two points is the first one, so that is the correct option.

Answer:

As both the mean and standard deviation are in the desired ranges, the tool passes the technical control.

Step-by-step explanation:

Mean of the batch:

The mean of the batch is the sum of all values divided by the number of items. So

[tex]M = \frac{199+204+201+197+195+204+200}{7} = 200[/tex]

Mean in the desired interval.

Standard deviation:

Square root of the sum of the difference squared between each term and the mean, divided by the number of items. So

[tex]S = \sqrt{\frac{(199-200)^2+(204-200)^2+(201-200)^2+(197-200)^2+(195-200)^2+(204-200)^2+(200-200)^2}{7}} = 1.18[/tex]

As both the mean and standard deviation are in the desired ranges, the tool passes the technical control.

Answer:

[tex]x=85^{\circ}[/tex]

Step-by-step explanation:

The sum of the interior angles of any polygon with five sides is equal to [tex](5-2)\cdot 180=3\cdot 180=540^{\circ}[/tex]. Therefore, we can set up the following equation and solve for [tex]x[/tex]:

[tex]115+95+115+130+x=540,\\455+x=540,\\x=\boxed{85^{\circ}}[/tex]

Answer:

  ∠A = 66°

Step-by-step explanation:

The other base angle (∠B) of this isosceles triangle is also 57°. Of course, the total of all angles is 180°, so we have ...

  ∠A +∠B +∠C = 180°

  ∠A + 57° + 57° = 180° . . . fill in the known numbers

  ∠A = 66° . . . . . . . . . . . . . subtract 114° from both sides

Answer:

The p-value of the test is 0.029.

Step-by-step explanation:

The mean area of homes in a certain city built in 2009 was 2438 square feet.

An insurance company wants to know if the mean area of homes built in 2010 is less than that of homes built in 2009.

This means that at the null hypothesis we test if the mean is the same as in 2009, that is:

[tex]H_0: \mu = 2438[/tex]

At the alternate hypothesis, we test that if it is less, than is;

[tex]H_a: \mu < 2438[/tex]

The test statistic is:

[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, s is the standard deviation and n is the size of the sample.

2438 is tested at the null hypothesis:

This means that [tex]\mu = 2438[/tex]

Assume that a simple random sample of 11 homes in the same city built in 2010 had a mean area of 2,293 square feet, with a standard deviation of 225 square feet.

This means that [tex]n = 11, X = 2293, s = 225[/tex]

Value of the test statistic:

[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]

[tex]t = \frac{2293 - 2438}{\frac{225}{\sqrt{11}}}[/tex]

[tex]t = -2.14[/tex]

Compute the P-value of the test.

Probability of finding a mean less than a value(in this case, 2293) is a one-tailed test.

The pvalue is found for a one-tailed test, with t = -2.14 and 11 - 1 = 10 degrees of freedom. With the help of a calculator, the pvalue of the test is of 0.029

The p-value of the test is 0.029.

Answer:

Step-by-step explanation:

So, the small red circles are the baskets.

Each 1 represents 1 basket.

We know that the two baskets on 4 wont be counted, as well as the two baskets on 4 1/2, since thats smaller than or equal to 4 1/2

We also know that the two baskets on 6 wont be counted either, since thats equal to 6.

So now lets count the baskets in between these values, which would be:

5 - 4 baskets

5 1/2 - 4 baskets

Lets add those up:

4+4

Answer:

29, 8

Step-by-step explanation:

1. let x = 1st number and y = 2nd number.

2. The 1st sentence translates into: x = 3y+5

3. 2nd sentence translates into: x + y = 37.

4. x+y = 37 --> y = 37-x

5. x = 3(37-x)+5

x = 111-3x +5

4x = 116

x = 29

y = 37-x = 37-29 = 8

6. x = 29, y = 8
