The probability that a girl is chosen is 1/10 and the probability that a left-handed girl is chosen is 11/20.
Probability may be defined as the possibility of occurrence of an event. Probability of an event can be 0 or 1 but it can never be negative. If probability is 0 then the event will not occur and if probability is 1 then the event will definitely occur. Probability is given by the formula.
Probability = Favorable outcomes/Total number of outcomes.
Here, total number of outcomes = 20.
Now in the first case we need to find probability of picking a girl so favorable outcome is 2.
Probability of picking a girl = 2/20
Probability of picking a girl = 1/10
In the second case we need to find probability of picking a left-handed girl, so the favorable outcomes are 2 + 9 = 11 as total number of girls are 2 and total number of left-handed people are 9.
Probability of picking left-handed girl = 9 + 2/20
Probability of picking left-handed girl = 11/20
Thus, probability that a girl is chosen is 1/10 and the probability that a left-handed girl is chosen is 11/20.

The length of the rectangle is 9 feet and the width of the rectangle is 10 feet.
What is the Perimeter of a Rectangle?The sum of a rectangle's boundary lengths on all sides is known as its perimeter. A rectangle's perimeter is a linear measurement that can be expressed in meters, feet, inches, or yards. Let's first comprehend the two fundamental characteristics of a rectangle.
A rectangle has four 90° angles.The lengths of a rectangle's diagonals are equal.Let the length of the rectangle be x feet
Then, the width of the rectangle will be x+1feet
We know that the perimeter of a rectangle is given by
P= 2(l+w)
Here
P= perimeter of a rectangle
l=length of the rectangle
w= width of the rectangle
Put l=x, w= x+1 and P= 38 in the perimeter formula
38 = 2(x+x+1)
Divide both sides by 2
19= x+x+1
19= 2x+1
Subtract 1 from both sides

Have a nice day!
A skier is trying to decide whether or not to buy a season ski pass. A daily pass costs $79. A season ski pass costs $350. The skier would have to rent skis with either pass for $30per day. How many days would the skier have to go skiing in order to make the season pass less expensive than the daily passes?
Answer:
Let s =cost of skiing per day. Here's what we know:
450 + 20s = 64s + 20s (the season pass plus ski rentals equates to daily skiing plus ski rentals)
We have 20s on both sides, so those cancel out easily:
450 = 64s
Divide both sides by 64:
7.03 ≈ s
You can't pay for a partial day, so the skier will have to ski for at least 8 days to make the season pass cheaper than getting daily passes.

The equation y = 2.391x +57.420 models the taste rating of a cereal, y, in a survey, where x is the number of grams of sugar per serving.
What does the y-intercept of the equation represent in context of the situation?
A cereal with 0 grams of sugar has a rating of about 57.
A cereal with 0 grams of sugar has a rating of about 2.391.
The average number of grams of sugar is 57.
The average number of grams of sugar is 2.
D
The y - intercept represents a cereal with zero grams of sugar that has a rating of about 57.
What is the general equation of a straight line?The general equation of a straight line is -
y = mx + c
where -
m → slope of line
c → y-intercept of line
Given a equation → y = 2.391x + 57.420 that models the taste rating of a cereal 'y' and 'x' represents the number of grams of sugar per serving.
The y-intercept of the equation represents the point at which the graph of the equation cuts the y - axis. Now, the coordinates of the y-intercept is of the form (0, y). Therefore, the x-coordinate will be 0. Now, the equation given is -
y = 2.391x + 57.420
Comparing it with the general equation of line -
y = 2.391x + 57.420
y = mx + c
The y - intercept is c = 57.420
At x = 0, the equation becomes -
y = 2.391 x 0 + 57.420
y = 57.420
Now -
Number of grams of sugar per serving = 0
Taste rating of a cereal = y = 57.420
Therefore, the y - intercept represents a cereal with zero grams of sugar that has a rating of about 57.

Determine whether each function is an example of exponential growth or decay. Then find the y -intercept.
y=0.6(1/10)x
The function y = 0.6 × ( 1/10)ˣ is a form of exponential decay and the value of y-intercept is 0.6.
The term "exponential decay" refers to the process of a constant percentage rate reduction in an amount over time. It can be written as y=a(1-b)ˣ, where x is the amount of time that has passed, a is the initial amount, b is the decay factor, and y is the final amount.
Consider the function,
y = 0.6 × ( 1/10)ˣ
This equation is a form of exponential decay because the number being raised in the power is a fraction, and whenever a fraction is raised to a positive power, the result decreases.
In order to determine the y-intercept of the function, we substitute the value of x as zero and find the value of y. Whenever a number is raised to zero power, the answer is always one.
Therefore,
y = 0.6 ( 1/10)ˣ
y = 0.6 × ( 1/10 )⁰

At the end of the summer, I decide to drain the swimming pool. I noticed that it drains

minutes. How many gallons are left in the pool after 50 minutes? About how many minutes will it take to have less than 1000 gallons in the pool? Justify your answer with a
mathematical model of the problem situation.
An exponential function can be defined as a mathematical function whose values are generated by a constant that is raised to the power of the argument. Mathematically, an exponential function is represented by this formula:
f(x) = eˣ
Generally speaking, a mathematical model for any quantity (water) that decreases by r percent per unit of time is an exponential function of this form:
P(t) = I(1 - r)^t
Where:
P(t ) represents the volume of water in gallons.t represents the time or number of years.I represents the initial volume of water.r represents the decay rate.Substituting the given parameters into the formula, we have;
P(t) = I(1 - r)^t
P(50) = 1500 × (1 - 0.3)^0.2{50}
P(50) = 1500 × (0.97)^10
P(50) = 1,106 gallons.
Therefore, there would be 1,106 gallons of water left in the pool after 50 minutes.
Next, we would determine the amount of time it would take to have less than 1000 gallons in the pool:
P(t) = I(1 - r)^t
1000 = 1500 × (1 - 0.3)^0.2t
1000 = 1500 × (0.97)^0.2t
1000/1500 = (0.97)^0.2t
2/3 = (0.97)^0.2t
Taking the log of both sides, we have:
log0.97(0.2t) = log(2/3)
t = log(2/3)/(0.27log0.97)

Given u = (-1, 3), v = ( 2, 4) , and w = (2, -5), by applying scalar multiplication of vectors, -3v = -3.( 2, 4) = (-6, -12)
In the two-dimensional coordinate system, vectors can be split into x-component and y-component.
We can write, for example, a vector s = (4,–2), which means:
x-component = 4
y-component = –2
Some vector operations:
Addition / subtraction of vectors: Just add or subtract the corresponding components.In the given problem:
u = (-1, 3), v = ( 2, 4) , and w = (2, -5)
Then,
-3 v = -3 . (2, 4)
= ( -3 . 2, -3 . 4)
= (-6, -12)
