PLEASE HELP! I WILL GIVE BRAINLIEST! Determine whether the statement is always, sometimes, or never true.
13. If a triangle is acute triangle, then it is an equilateral triangle.
14. If a triangle has two acute angles it must be an acute triangle. 15.An obtuse triangle can have a right angle.

Answers

Answer 1

Answer:

Step-by-step explanation:

13.  All equilateral triangles are acute triangles. An equilateral triangle has three sides of equal length and three equal angles of 60.~ I think it is False.

14. If a triangle has two acute angles, then the third angle must also be acute.~ I think it is true.

15.  A triangle cannot be right-angled and obtuse angled at the same time. Since a right-angled triangle has one right angle, the other two angles are acute. Therefore, an obtuse-angled triangle can never have a right angle; and vice versa. ~I think it is false.

Please don't trust me... I hope I helped

g Around 20 years ago, the CDC learned of an outbreak of gastrointestinal illness in several Georgia elementary schools. The CDC began their investigation by examining a random sample of 452 children. Among these children, 145 out of 304 became ill after eating burritos served by their school's cafeteria. On the other hand, only 20 of the remaining 148 who did not eat burritos became ill. (a). (3 points) Using this data, give a point estimate for the true difference in the proportion of those that ate the burrito and those that did not eat the burrito who developed a gastrointestinal illness.

Answers

Answer:

The point estimate is 0.342.

Step-by-step explanation:

Among these children, 145 out of 304 became ill after eating burritos served by their school's cafeteria.

This means that:

[tex]p_B = \frac{145}{304} = 0.477[/tex]

On the other hand, only 20 of the remaining 148 who did not eat burritos became ill.

This means that:

[tex]p_{NB} = \frac{20}{148} = 0.135[/tex]

a). (3 points) Using this data, give a point estimate for the true difference in the proportion of those that ate the burrito and those that did not eat the burrito who developed a gastrointestinal illness.

The point estimate is the subtraction of the sample proportions. So

[tex]p = p_N - p_{NB} = 0.477 - 0.135 = 0.342[/tex]

The point estimate for the true difference in the proportion of those that ate the burrito and those that did not eat the burrito who developed a gastrointestinal illness is 0.342.

The HL theorem basically says that two triangles are congruent if their corresponding hypotenuses and one leg are equal.

Here, the hypotenuse of both triangles are each marked with two dashes meaning they're equal. Similarly, QE and ET are both equal.

Therefore we can see that they can be proved congruent by the HL Theorem.

SSS - The two triangles share all 3 sides, proving they are congruent.

Step-by-step explanation:

Two sides of each triangle are marked in the diagram as equal. The third side, [tex]\overline{BD}[/tex] is shared between both sides, meaning that both triangles share all three sides. This is known as SSS (side-side-side) and is a proof of congruence.

Step-by-step explanation:

If the radius of a cylinder is 3 centimeters, then the area of one of the circular bases is 18.84 square centimeters. True False

Answers

Answer:

false

Step-by-step explanation:

Answer:

False

Step-by-step explanation:

To calculate the area of a circle you need to multiply the radius by itself, then multiply that number by [tex]\pi[/tex].

In this case, our radius is 3, so we multiply 3 × 3 × [tex]\pi[/tex] (which can be estimated as 3.14)

3×3 is 9

9×3.14 is 28.26

28.26≠18.84

XYZ has vertices X(15,−8), Y(13, 21), and Z(−17, 17). Which of the following represents the translation of △XYZ along vector <−6, 5> and its reflection across the x-axis?

Answers

Answer:

X (15, −8) → X ′(9, −3) → X ″(9, 3);

Y (13, 21) → Y ′(7, 26) → Y ″(7, −26);

Z (−17, 17) → Z ′(−23, 22) → Z ″(−23, −22)

Step-by-step explanation:

Use the translation vector <−6, 5>  to determine the rule for translation of the coordinates: (x, y)→ (x+(−6),y + 5).

Apply the rule to translate vertices X(15 ,−8), Y(13, 21) , and Z(−17, 17) .

X (15,−8) → (15 + (−6),−8 + 5) → X'(9, −3).

Y (13, 21) → (13+ (−6), 21 + 5) → Y' (7, 26).

Z (−17, 17) → (−17 + (−6), 17 + 5) → Z' (−23, 22).

To apply the reflection across x-axis use the rule for reflection: (x, y) → (x, −y).

Apply the reflection rule to the vertices of △X'Y'Z'.

X' (9, −3) → X'' (9, 3).

Y' (7, 26)→Y''(7, −26).

Z' (−23, 22) → Z'' (−23, −22).

Therefore,

X (15 ,−8) → X' (9, −3) → X'' (9, 3)

Y (13, 21) → Y' (7, 26) → Y'' (7, −26)

Z (−17, 17) → Z' (−23, 22) → Z'' (−23, −22)

represents the translation of △XYZ along vector <−6, 5>  and its reflection across the x-axis.

Essentially, it is sweetened water added to fruit puree that is churned and then frozen. It differs from regular ice cream and other frozen desserts because it contains no dairy, like cream or milk. As a result, sorbet has a very low fat content. With a low fat content, it means that sorbet needs to be served a little differently than regular ice cream. It needs to be stored at a lower temperature in order to scoop it into a cup or cone easily. If it is not stored at a lower temperature, it is frozen solid like an ice cube.The story of sorbet begins with the Roman Emperor, Nero, and his travels during the first century. The legend states that Nero established a line of runners from Italian cities to high up in the mountains. This allowed buckets of snow to travel from the mountains to his banquet hall whenever he pleased. Since fresh snow was so hard to get, only the richest families enjoyed the frozen dessert. Due to the lack of technology, fresh snow had to be retrieved from the mountains constantly if Nero wanted to eat the dessert. There was nowhere to keep it frozen so it would melt. Since Nero wanted a constant supply of the dessert, he needed a group of workers to keep fetching it from the mountains. Nero liked to flavor the fresh snow with honey and that's essentially what sorbet is, water and flavoring. This is the first record account of sorbet, which lead to other frozen desserts, like traditional ice cream.Select two details from the passage that support the main ideas that sorbet is different than ice cream, and sorbet dates back to Roman Emperor, Nero, in the first century.Group of answer choices"It differs from regular ice cream and other frozen desserts because it contains no dairy, like cream or milk." . . .
