Martina read that approximately 10% of all people are left-handed. She wants to design a simulation to approximate the probability of selecting exactly 2 right-handed people when 3 people are randomly selected. Martina spins the arrow on the spinner 3 times and records the resulting letters. Martina performs the simulation 30 times. The results of the simulation are shown.

Question 3 options: 10% 15% 20% 25%
Answer: 10%
Step-by-step explanation:
The probability of selecting exactly 2 right-handed people are approximately 20% of the time.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.
The results of the simulation are shown.
RRR RLR RRR RRL RRR RRR RRR RRR RRR LRR RRR RRR RRR RRR RRR RRR RLR LRL RRR RRL RRR RRR LLR RRR RRR RRR LRR RRR RRR RRR
Here, probability = 6/30
= 1/5
= 0.2
= 0.2×100
= 20%
Therefore, probability of selecting exactly 2 right-handed people are approximately 20% of the time.

What is Coordinates?A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.
Given that;
On a coordinate plane,
Point B is at (- 8, 10),
Point C is at (8, 10),
Point D is at (2, - 2),
Point E is at (- 8, - 4).
Now, We know that;
The distance between two points (x₁ , y₁) and (x₂, y₂) is,
⇒ D = √ (x₂ - x₁)² + (y₂ - y₁)²
Thus, The length of side BC is,
⇒ D = √ (x₂ - x₁)² + (y₂ - y₁)²
⇒ D = √ (8 - (-8))² + (10 - 10)²
⇒ D = √ 16²
⇒ D = 16
Thus, The length of side CD is,
⇒ D = √ (x₂ - x₁)² + (y₂ - y₁)²
⇒ D = √ (2 - 8)² + (-2 - 10)²
⇒ D = √ -6² + (-12)²
⇒ D = √ 36 + 144
⇒ D = √ 180
⇒ D = 13.4
Thus, The length of side ED is,
⇒ D = √ (x₂ - x₁)² + (y₂ - y₁)²
⇒ D = √ (2 - (-8))² + (-2 - (-4))²
⇒ D = √ 10² + 2²
⇒ D = √104
⇒ D = 10.2
Thus, The length of side BE is,
⇒ D = √ (x₂ - x₁)² + (y₂ - y₁)²
⇒ D = √ (- 8 - (-8))² + (10 - (-4))²
⇒ D = √ 14²
⇒ D = 14

A zookeeper is 6 and 1/4 feet tall. A young giraffe in her care is 9 and 3/8 feet tall. What fraction of the giraffes height is the zookeepers?
Answer:
3 1/8
Step-by-step explanation:
Subtract and then simplify
Answer:
Step-by-step explanation:
1. You know that:
- The zookeeper is 6 1/4 feet tall.
- The young giraffe is 9 3/8 feet tall.
2. Then, to calculate how many times as tall as the zookeeper is the girraffe, you only need to divide the height of the giraffe by the height of the zookeeper:
- Let's rewrite each height as a decimal number: divide the numerator and the denominator of the fraction and add the result to the whole number:
- Divide 9.375 feet by 6.25 feet, then you obtain the following result:

Drag and drop the choices into the boxes to correctly complete the table.
corresponding alternate interior alternate exterior none of these
Answer:
alternate exteriornone of these (consecutive exterior)correspondingalternate interiorcorrespondingStep-by-step explanation:
The above list is for the figures numbered 1-3 (left to right) on the top row, and 4-5 (left to right) on the bottom row.
__
"Alternate" angles are on opposite sides of the transversal. If the angles are between the parallel lines, they are "interior" (fig 4). If they are outside the parallel lines, they are "exterior" (fig 1).
"Corresponding" angles are found in the same direction from the point of intersection. Upper-left corresponding angles are seen in fig. 3; lower-right corresponding angles are seen in fig. 5.
The angles marked in figure 2 are "consecutive exterior" angles, also called "same-side exterior" angles. The applicable descriptive choice in this problem is "none of these".
