Step-by-step explanation:
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.
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
Based on the results of this simulation, when 3 people are randomly selected, exactly 2 right-handed people are selected approximately _______ of the time. Question 3 options:
10%
15%
20%
25%
To approximate the probability of selecting exactly 2 right-handed people when 3 people are randomly selected, we need to look at the simulation results and count the number of times exactly 2 right-handed people were selected.
From the simulation results, we can see that there are 6 instances where exactly 2 right-handed people were selected:
RLR
RRL
LRR
LLR
RRL
LRR
Out of the 30 simulations, this means that 6/30 or 1/5 or 20% of the time, exactly 2 right-handed people were selected when 3 people are randomly selected.
Therefore, the answer is 20%.

Step-by-step explanation:
Veronica spent a minimum of $65 on a doll and accessories for the doll. The doll cost $26 and the accessories cost $13 each. Write an inequality can be used to find the possible values for x, the number of doll accessories Veronica could have bought.
Answer: [tex]13x+26 \ge 65[/tex]
If you solve for x, you get [tex]x \ge 3[/tex] which means she bought at least 3 accessories.
=========================================================
Explanation:
x = number of accessories, some nonnegative whole number
13x = amount spent on accessories only
For instance, let's say she bought 5 accessories. This means she spent 13x = 13*5 = 60 dollars on those five items.
This is on top of the $26 Veronica paid for the doll itself (without the accessories). In total, she spent 13x+26 dollars for the doll (26) and the accessories (13x) combined.
We're told she spent a minimum of $65, which means that she spent 65 or more dollars.
So the total cost (13x+26) must be equal to 65 or larger than 65.
We write that as [tex]13x+26 \ge 65[/tex] which sets up the inequality.
----------------------------
Let's solve for x
[tex]13x+26 \ge 65\\\\13x \ge 65-26\\\\13x \ge 39\\\\x \ge 39/13\\\\x \ge 3\\\\[/tex]
So x can be equal to 3, or larger than it.
The lowest value x can be is 3.
Meaning that she bought at least 3 accessories (ie she bought 3 or more accessories).
Answer:
Step-by-step explanation:
65= 26+13x

A cube has a volume of 27 cubic centimeters. What is its surface area ?
Show all work below and be sure to use units in your answer. !!
NO WORK = NO CREDIT = REPORT !!
Answer:
A≈54cm²
Step-by-step explanation:
Answer:
54 cm²
Step-by-step explanation:
Since it's a cube all sides must be equal. So, the length of one side is equal to the cube root of the volume.
∛27 = 3
An area of one surface is 3² = 9
Since the area of all the surfaces of the cube are equal, we can say that the surface area of the cube is 9 x 6, because there are 6 faces on a cube.
9 x 6 = 54
So, this means that the surface area of the cube is 54 cm².

What is Pythagoras theorem?The Pythagorean theorem, or Pythagorean theorem, illustrates the relationship between the three sides of a right-angled triangle. The square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle, according to the Pythagorean theorem.
We know,
Kyle held a balloon 8 feet off the ground.
Ava is standing 15 feet directly to the right of Kyle.
So, height = 8 ft and distance = 15 ft
Using Pythagoras theorem
x² = 8² + 15²
x² = 64+ 225
x = 17 unit
Thus, the value of x is 17 unit.
