Answer:6%
Step-by-step explanation:
Work it out smh
The probability that there is a left-handed person in a group of 5 randomly selected people is 6%
It is given that Greta learned that about 10% of people are left-handed.
It is required to find the probability that there is a left-handed person in a group of 5 randomly selected people.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
We have a total number of people = 50 (because 10 rows and 5 columns)
In the question, it is given that the 0 represents a left-handed person.
Then the number of left-handed people = 3 (there are three zero's in the table)
We know:
[tex]\rm Probability = \frac{ favorable \ outcomes}{total \ outcome}[/tex]
[tex]\rm Probability= \frac{3}{50}[/tex]
Probability = 0.06 or
Probability = 0.06×100 ⇒ 6%
Thus, the probability that there is a left-handed person in a group of 5 randomly selected people is 6%

1. Write the equation of a line that is parallel to y = -1/4 x - 6 that passes through the point (12,4).
Answers
Answer:
The answer is
[tex]y = - \frac{1}{4} x + 7[/tex]Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
To find the equation of the parallel line we must first find the slope of the original line
From the question the original line is
y = - 1/4x - 6
Comparing with the general equation above
Slope = - 1/4
Since the lines are parallel their slope are also the same
Slope of parallel line = - 1/4.
Equation of the line using point (12,4) and slope - 1/4 is
[tex]y - 4 = - \frac{1}{4} (x - 12) \\ y - 4 = - \frac{1}{4} x + 3 \\ y = - \frac{1}{4} x + 3 + 4[/tex]
We have the final answer as
[tex]y = - \frac{1}{4} x + 7[/tex]

Corresponding angles are angles on the same side of two lines that are crossed by a given transversal
Alternate interior angles are angles on the inner but opposite sides of two lines crossed by a transversal
Alternate exterior angles are angles on the outer but opposite sides of two lines crossed by a transversal
Consecutive interior angles are angles that are next to each other on the same side of the transversal and in between the two lines.

Which equation can be used to determine the distance between the pirate and the treasure, in yards?
A |4.5| − | − 10.3| = −14.8 B |4.5|−|−10.3|= −5.8 C |4.5−10.3|=5.8
D |4.5−(−10.3)|=14.8
Answers
Answer:
The answer is A
Step-by-step explanation:
The equation that should be used for determining the distance is |4.5| - | - 10.3| = -14.8.
Given that,
The pirate stands on the ship 4.5 yards above the seal level.And, the treasure is 10.3 yards below sea level.Based on the above information, the equation that should be used is |4.5| - | - 10.3| = -14.8.
Therefore we can conclude that the equation that should be used for determining the distance is |4.5| - | - 10.3| = -14.8.

Part A: Write an inequality to describe the amount of meals you can by based on
your budget constraint.
hey y’all if you could tell me how to do that it’s be epic thanks ❤️
Answers
Step-by-step explanation:
x+y<=149.25x+11.75y<=100Step one:
given that lunch cost $9.25 per meal
and dinner cost $11.75 per meal
Note: you are to eat twice in a day for seven days
so the total number of meals will be 2*7= 14 meals
also, your budget is $100 for these 14 meals, hence you must not spend past this value of $100
step two:
let the numbers of Lunch be x
and the number of Dinners be y
Therefore
the inequality based on the number of meals based on the constraints is
[tex]x+y\leq 14\\\\ 9.25x+11.75y\leq 100[/tex]
