Answer:

The correct option is;

30° - 60° - 90°

Step-by-step explanation:

Rotation is one of the three rigid transformation of which others are reflection and translation. In a rotation transformation of a figure about a fixed point, known as the center of rotation, the figure is turned in a circular path about the fixed point or center of rotation. The size and shape of the pre-image the rotation are the same however, depending on the angle of rotation, their facing directions may be different. The specification of a rotation can be in the clockwise direction or in the anti-clockwise direction

The shape of the triangle in the question and the image are the same and are therefore congruent. All interior angles of the triangle and those of its rotation will therefore be congruent.

HELP Sam measures the height of 7 different scoops of ice cream. The mean of the heights was 3.8 cm. Which of the following best

OLga [1]

Sam measures the height of 7 different scoops of ice cream. The mean height was 3.8 cm. If all the scoops are evenly distributed, they would all be 3.8 cm tall.

<h3>How to find the mean value of a data set?</h3>

The mean value of the data set is the ratio of the sum of the data set's values to the number of values it has.

If the data set consists of values

x_1, x_2, ..., x_n

, then we get the mean value as:

$\overline{x} = \dfrac{x_1 + x_2 + \cdots + x_n}{n}$

Sam measures the height of 7 different scoops of ice cream. The mean height was 3.8 cm.

$\overline{x} = \dfrac{x_1 + x_2 + \cdots + x_n}{n}$

mean= $\dfrac{(a+b+c+d+e+f+g)}{7}$

Therefore, If all the scoops are evenly distributed, they would all be 3.8 cm tall.

Answer:

Final answers are ,

• 9

•-7

• 7

• -85

Step-by-step explanation:

Given that when we input a number then first it will be multiplied by 2 and finally decreased by(-1) .

Input 5 :-

• Firstly Multiplying it by 2 → 2× 5 = 10

• Subtracting 1 from it → 10 - 1 = 9

Output = 9

====================================

Input (-3) :-

• Firstly Multiplying it by 2 → 2× -3 = -6

• Subtracting 1 from it → -6- 1 = (-7)

Output = (-7)

====================================

Input 4 :-

• Firstly Multiplying it by 2 → 2× 4 = 8

• Subtracting 1 from it → 8 - 1 = 7

Output = 7

====================================

Input (-42) :-

• Firstly Multiplying it by 2 → 2× -42 = -84

• Subtracting 1 from it → -84 - 1 = -85

Output = (-85)

====================================

Answer:

The answer is A.

Step-by-step explanation:

All you have to do is find the slope, which is given in the question and then count it and see what line goes with the slope you were given.

1/3 is the slope so count that to check your work, and it works out :)
