The first step in simplifying the expression 2(x+3)+5 = 2x+2(3)+5.

Given expression in 'x' is 2(x+3)+5.

In order to simplify this expression, we need to expand it by opening the parenthesis. That is, we need to distribute 2 over (x+3) first. For this we multiply 2 into (x+3) and then only we can add 5 to it.

So, 2(x+3) +5 = 2x + 2(3) +5

                     = 2x +6 +5

                     = 2x+11

If for every ordered pair (m,n) is in ℤ×ℤ, "m P n" ⇔ m and n have a common prime factor , then yes "10 P 35" because 10 and 15 share a common prime factor of 5.

The Relation "P" on ℤ is defined as follows: For every ordered pair (m, n) in ℤ ✕ ℤ, "m P n" if and only if m and n have a common prime factor.

To determine whether 10 P 15, we need to check if 10 and 15 have a common prime factor.

The prime factors of 10 are 2 and 5, whereas the prime factors of 15 are 3 and 5.

So , 10 and 15 share a common prime factor of 5.

Therefore , we can conclude that "10 P 15".

Dilation refers to the transformation of an object in such a way that it becomes larger or smaller but preserves the same shape. The scale factor determines the degree of magnification or reduction. There are two types of dilation; enlargement and reduction.

Determine the type of dilation shown and the scale factor used.Enlargement with a scale factor of 1.5An enlargement is a type of dilation that makes an object bigger.

The scale factor is the ratio of the corresponding lengths. In this case, the original length is multiplied by 1.5 to obtain the new length. The scale factor is greater than 1, indicating that the image is larger than the pre-image.

This is a uniform scale factor. Example: If the original length is 4 cm, the new length is 4 × 1.5 = 6 cm.Enlargement with a scale factor of 2.5An enlargement with a scale factor of 2.5 is similar to the previous example. The original size is multiplied by 2.5 to get the new size.

This is also a uniform scale factor. The image is larger than the pre-image, as indicated by the scale factor of 2.5. Example: If the original length is 3 cm, the new length is 3 × 2.5 = 7.5 cm.Reduction with a scale factor of 1.5A reduction is a type of dilation that makes an object smaller.

The scale factor is less than 1. In this case, the original length is multiplied by 0.67 (which is 1/1.5) to get the new length. The image is smaller than the original, as indicated by the scale factor of 0.67. This is also a uniform scale factor. Example: If the original length is 6 cm, the new length is 6 × 0.67 = 4.02 cm.

Reduction with a scale factor of 2.5A reduction with a scale factor of 2.5 is similar to the previous example. The original size is multiplied by 0.4 to get the new size. The image is smaller than the pre-image, as indicated by the scale factor of 0.4. This is also a uniform scale factor.

Example: If the original length is 5 cm, the new length is 5 × 0.4 = 2 cm.

Step-by-step explanation:

It is given that 9 cat owners and 13 dog owners chose "Wet food". 10 cat owners and 14 dog owners chose "Dry food".

Cat owners-Wet food = 9

Dog owners-Wet food =13

Cat owners-Dry food = 10

Dog owners-Dry food =14

We need to construct a two-way frequency table for the data.

Take owners in the first row and type of food in first column and construct a two-way frequency as shown below:

Answer and Step-by-step explanation:

Sin = \(\frac{Opposite}{Hypotenuse}\)

Cos = \(\frac{Adjacent}{Hypotenuse}\)

Tan = \(\frac{Opposite}{Adjacent}\)

sin A = \(\frac{10}{26} = \frac{5}{13}\)

cos A = \(\frac{24}{26} = \frac{12}{13}\)

tan A = \(\frac{10}{24} = \frac{5}{12}\)

Answer:

D) (-5, - 7)

Step-by-step explanation:

Because both lines intersect, they must share a point (have same x and y coordinates).

\(2x + 3 = - 4x - 27\)

\(2x = - 4x - 30\)

\(6x = - 30\)

\(x = - 5\)

Substite x for - 5 in any of the equations to find the y coordinate.

\(y = 2( - 5) + 3 \)

\(y = - 10 + 3\)

\(y = - 7\)

The x coordinate for the intersection point is - 5 and the y coordinate is - 7. The intersection point is (-5, - 7)

Since TV bisects ∠STU:

The correct answer is “This is a right-tailed test because a direction is specified. The population parameter is greater than the specified value.”

What is hypothesis testing?

In hypothesis testing, we test the null hypothesis against the alternative hypothesis. The null hypothesis (H0) is the default assumption, which states that there is no significant difference between the sample data and the population parameter. The alternative hypothesis (H1) contradicts the null hypothesis and suggests that there is a significant difference between the sample data and the population parameter.

In this scenario, the null hypothesis would be that the average number of keywords per web page is less than or equal to 10, and the alternative hypothesis would be that the average number of keywords per web page is greater than 10.

Since the alternative hypothesis specifies a direction, it is a one-tailed or one-directional test. Moreover, as the alternative hypothesis states that the average number of keywords per web page is greater than 10, the critical region is in the right tail of the distribution. Therefore, this is a right-tailed test.

So, the correct answer is: This is a right-tailed test because a direction is specified. The population parameter is greater than the specified value.

1. Assign the digits 0-41 to represent the vowels in the bag.
2. Assign the digits 42-97 to represent the consonants in the bag.
3. Assign the digits 98-99 to represent the blank tiles in the bag.

To simulate drawing a tile:
1. Generate a random number between 0 and 99.
2. If the number falls between 0 and 41 (inclusive), consider it a vowel.
3. If the number falls between 42 and 97 (inclusive), consider it a consonant.
4. If the number falls between 98 and 99 (inclusive), consider it a blank tile.

The area of the unshaded portion of the sector is 9.17 cm².

The shaded sector in the circle is 56.87 centimetres squared.

Therefore, the unshaded portion of the sector can be found as follows:

Let's find the radius of the circle,

56.87 = ∅ / 360 × πr²

56.87 = 310 / 360 × 3.14 × r²

56.87 = 973.4 / 360 r²

56.87 = 2.70388888889 r²

divide both sides by 2.70388888889

r² = 56.87 / 2.70388888889

r = √21.0326690022

r = 4.5861312672

r = 4.59 cm

Therefore,

area of the unshaded sector = 50 / 360 × 3.14 × 4.59²

area of the unshaded sector = 3302.1182 / 360

area of the unshaded sector = 9.17255055556
