A family has 5 children. Assume that each child is as likely to be a boy as it is to be a girl. Find the probability that the family has 5 girls if it is known that the family's first child is a girl.
The required probability is 1/31 that the family has 5 girls if it is known that the family's first child is a girl.
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
Let us express every possible set of 5 children as a 5-letter word made up of the letters G or B. (G for a girl and B for a boy).
In all, 2⁵ = 32 such words are outcomes, with two options for each of the five slots.
The constraint "if it is known that the family contains at least one female" suggests that we would evaluate the reduced space of all such words, except the word (BBBBB).
This reduced event space is made up of 32-1 = 31 elements.
There is just one such term in the favorable collection of events (GGGGG).
As a result, the probability for the question is P = 1/31.

Liz bought seven liters of orange juice for a party. About how many quarts of juice did she buy?
Let's make a conversion:
[tex]7l\times\frac{1.05669qt}{1l}=7.39683qt\approx7.40qt[/tex]She bought about 7.39683qt
Liz bought 7.396817 quarts of orange juice for a party.
What are Quarts?The liquid quart in the United States is a measure of fluid volume equal to one-fourth of a gallon, two pints, or four cups. The liquid quart is not to be confused with the dry quart (US) or the imperial quart, which are two distinct units.
Multiply the volume by the conversion ratio to transform a liter measurement into a quart measurement.
Since each liter equals 1.056688 quarts, you may use the following easy formula to convert:
quarts = liters × 1.056688
The volume in quarts is equal to the liters multiplied by 1.056688.
We have been given that Liz bought seven liters of orange juice for a party.
We have to convert 7 liters to quarts using the formula above.
7 L = (7 × 1.056688) = 7.396817 qt
Thus, she bought 7.396817 quarts of orange juice for a party.

[tex]\begin{gathered} f(-4)=-\frac{4}{3} \\ f(1)=4 \\ f(3)=1 \end{gathered}[/tex]Step-by-step explanation:
These types of functions are called Piecewise-defined functions since it use a different formula for different parts of its domain because it has a point of discontinuity.
We have the following function:
[tex]f(x)=\begin{cases}-\frac{1}{3}x^2+4\rightarrow ifx\ne1^{} \\ \text{ 4 if x=1}\end{cases}[/tex]So, to find f(-4), we need to substitute x=-4 into the function for x≠1.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
A ( t ) = 224 - 16t , where t is the number of trips
a)
The amount of money does Ahmad have left in the account after 11 trips on the toll roads be P
Substituting the value of t = 11 in the equation , we get
A ( 11 ) = 224 - 16 ( 11 )
A ( 11 ) = 224 - 176
A ( 11 ) = $ 48
So , The amount of money does Ahmad have left in the account after 11 trips on the toll roads is $ 48
b)
The number of trips on the toll roads can he take until his account is empty be n
when A ( t ) = 0
224 - 16t = 0
Adding 16t on both sides of the equation , we get

what are three consecutive integers that add to 40
Answer:
12 1/3 + 13 1/3 + 14 1/3 = 40
Step-by-step explanation:
Here we will use algebra to find three consecutive integers whose sum is 40. We start by assigning X to the first integer. Since they are consecutive, it means that the 2nd number will be X + 1 and the 3rd number will be X + 2 and they should all add up to 40. Therefore, you can write the equation as follows:
Indicate whether the following statements are True (T) or False (F). 1. The product of two real numbers is always a real number. 2. The quotient of two real numbers is always a real number (provided the denominator is non-zero). 3. The ratio of two real numbers is never zero. 4. The difference of two real numbers is always a real number. 5. The sum of two real numbers is always a real number. 6. The quotient of two real numbers is always a rational number (provided the denominator is non-zero). 7. The difference of two real numbers is always an irrational number.
The required answer is true, false, true, false, true, true, and false for statements 1, 2, 3, 4, 5, 6, and 7 respectively.
The product of two real numbers is always a real number is true.
The quotient of two real numbers is always a real number (provided the denominator is non-zero) is false because when you divide, you get the quotient, and when you divide, you might get decimals.
The ratio of two real numbers is never zero is true.
The difference of two real numbers is always a real number is false because it could be a decimal.
The sum of two real numbers is always a real number is true.
The quotient of two real numbers is always a rational number (provided the denominator is non-zero) is true.
The difference of two real numbers is always an irrational number is false.

Given the equation:
[tex]-4y=12+2x[/tex]To find the slope of the equation, solve the equation for (y)

[tex]y=mx+b[/tex]So, for the given equation, divide all terms by (-4)
So,
[tex]\begin{gathered} \frac{-4y}{-4}=\frac{12}{-4}+\frac{2x}{-4} \\ \\ y=-3-\frac{1}{2}x \\ \\ y=-\frac{1}{2}x-3 \end{gathered}[/tex]compare the last result with the slope-intercept form
So, the slope = m = -1/2

[tex]\text{slope}=-\frac{1}{2}[/tex]Identify the variables, coefficients, and constants of the following equations.
3x = 12
y = 1/2x - 6
Answer:
Variables are the letters that represent a number. So, it would be the ones bolded here: 3x=12 and y=1/2x-6
The coefficients are next to the variables-the ones being multiplied with the variable. They are bolded here: 3x= 12 and y= 1/2x-6
The constants are the numbers that aren't coefficients or variables. So they are bolded here: 3x=12 and y=1/2x-6
If you had half a dollar, three quarters, eight dimes, six nickels, and nine pennies, how much money would you have altogether?
If we have half a dollar, three quarters, eight dimes, six nickels, and nine pennies , then we altogether have $2.44 .
In the question ,
it is given that
we have half a dollar ,
which means half a dollar = $0.50
we have , three quarters means
we have 75 cents
and 75 cents = $0.75
we have 8 dimes ,
we know that 1 dime [tex]=[/tex] 10 cents
so , 8 dimes = 80 cents
and 80 cents = $0.80
we have six nickels,
we know that 20 nickels = $1
so , 1 nickel = $1/20
and 6 nickel = $ 6/20 = $0.30
we have nine pennies ,
we know that 100 pennies = $1
So ,1 Pennie = $1/100
and 9 pennies = $ 9/100 = $0.09
Combining all together we get
total money = half a dollar + three quarters + 8 dimes + six nickels + nine pennies .
Substituting the values , we get
total money = $0.50 + $0.75 + $0.80 + $0.30 + $0.09
= $2.44

The function f(x)= -200x+1000 represents the altitude (in feet) of a paraglider x minutes from the time the paraglider begins a descent to a landing site located 100 feet above sea level. Identify the slope, domain, and range.
The slope of the Function is -200, the domain of the function is any real value of x and the range of the function is [1000,∞).
The provided function is,
f(x) = -200x+1000
This function is representing the altitude of a paraglider and time from where the paraglider descent. Here, x is representing time in minutes.
The landing site is located at the depth of 1000 feet.
we can write the function as,
y = -200x + 1000
Here, y is the range of the function.
As we observes the function, it is an equation of line,
So, the slope is equal to the coefficient of x.
So the slope is -200.
The domain is any value of x for which the function is defined,
as this it an equation of line,
The domain would be any real value of x.
The range is the output that we get after putting value of x.
Here,
Put x = 0.
y = -200(0)+1000
y = 1000
Now. putting x = -1,
y = -200(-1) + 1000
y = 1200.
Putting any negative value of x will make y positive,
So, the range will be [1000,∞)
