Final answer:

The conditional probability of drawing a white ball on the second draw after a blue ball has been drawn on the first draw from a bag of balls without replacement is 2/7.

Explanation:

The question asks for the probability of drawing a white ball on the second draw, given that a blue ball has been drawn on the first draw (P(B|A)) from a bag containing 4 blue balls, 7 yellow balls, and 4 white balls, without replacement.

Firstly, we calculate the total number of balls in the bag: 4 blue + 7 yellow + 4 white = 15 balls.

For event A (drawing a blue ball first), there are 4 ways this can happen out of 15 total possibilities, so the probability of A is 4/15. After a blue ball is drawn, there are now 14 balls left in the bag for the second draw.

Since event B is drawing a white ball as the second ball, given that a blue ball has already been drawn on the first draw, there are still 4 white balls left in the bag after event A has occurred. Therefore, the probability of B given A is 4/14, which simplifies to 2/7.

Thus, P(B|A) = 2/7.

Answer:

8, 13, 18

Step-by-step explanation:

If we want the mean to be 13, and there are 3 integers, that means the sum of all 3 integers must be 39. I started at 13 and counted 5 up and 5 down, which already makes sure of the range and the mean is 13 (since it's balanced with 13 being the middle), therefore, 13+5 is 18, 13-5=8.

Answer:

3181 yards.

Step-by-step explanation:

All the given information can be used to draw a simple diagram. The diagram shows a triangle which is formed by the ships. There are two angles given and one side is given. Therefore, the sine rule must be used to solve the question. The sine rule can be written as:

sin V / v = sin G / g.

It can be observed that the angle V is unknown, however, it can be calculated very easily. Simply use the law of triangle in which all the 3 angles sum up to 180 degrees. So V = 180 degrees - 44 degrees - 36 degrees = 100 degrees. So plugging in v = 4510 yards, V = 100 degrees, G = 44 degrees, and g = x yards into the sine rule gives:

sin 100 / 4510 = sin 44 / x.

Cross multiplying gives:

x*sin 100 = 4510*sin 44

Making x the subject gives:

x = (4510*sin 44)/sin 100.

x = 3181 yards (to the nearest yard).

Therefore, Norman and Voyager are 3181 yards apart from each other!!!

Answer:

[tex]\$300[/tex]

Step-by-step explanation:

In this problem we have a exponential function of the form

[tex]f(x)=a(b)^{x}[/tex]

where

a is the initial value ( value of the function when the value of x is equal to zero)

b is the base

r is the rate

b=1+r

we have

[tex]f(x)=300(1+0.03)^{x}[/tex]

therefore

The term that represents the amount of money originally deposited in the account is the initial value

For x=0

substitute

[tex]f(0)=300(1+0.03)^{0}[/tex]

[tex]f(0)=\$300[/tex]

Answer:

The correct option is 1.

Step-by-step explanation:

The function is

[tex]f(x)=300(1+0.03)^x[/tex]

We need to find the term that represents the amount of money originally deposited in the account. It means we need to find the initial amount.

Substitute x=0 in the given function, to find the initial value of the function.

[tex]f(0)=300(1+0.03)^(0)[/tex]

[tex]f(0)=300(1)[/tex]

[tex]f(0)=300[/tex]

The term 300 represents the amount of money originally deposited in the account. Therefore the correct option is 1.

Answer:

50 degrees

Step-by-step explanation:

all inside angles in every triangle can be added up to equal 180 degrees.

this is a right angle, so one has to be 90 degrees

on the bottom right it's marked 140 degrees on the outside, in order to find the inside angle, you need to subtract 140 from 180, which gives you 40 degrees

180-90=90

90-40=50

so the answer is 50

if that's not clear enough leave a comment, hope this helps!

Answer:

50°

Step-by-step explanation:

Inside angles of a triangle = 180°

The triangle shown is a right triangle.

Therefore, it is 90°

180 - 90 = 90

90 - 40 = 50

Answer = 50°

In geometry, you can use deductive rules to prove conjectures

A coordinate geometry is a branch of geometry where the position of the points on the plane is defined with the help of an ordered pair of numbers also known as coordinates.

Deductive reasoning is used in geometry to start with a set of given premises or axioms, and then use logical reasoning and previously established theorems to draw conclusions or prove conjectures.

The main use of deductive rules in geometry is to prove conjectures.

A conjecture is considered proven only when it has been shown that it is logically impossible for it to be false.

Hence, in geometry, you can use deductive rules to Prove conjectures

Answer:

d. 288π in3

Step-by-step explanation:

The volume of a sphere is given by

V = 4/3 pi r^3

The radius is 6

V = 4/3 pi 6^3

V = 288 pi in^3

Answer:

7.5 mph.

Step-by-step explanation:

Speed downstream = d / 3 = 30 + x    where d = the distance , x =speed of the stream.

Speed upstream = d  / 5 = 30 - x.

30 + x = d/3

30 - x = d/5

Adding the 2 equations

60 = d/3 + d/5

8/15 d = 60

d = 60 * 15 / 8 =  112.5 miles.

Now calculate x , the speed of the stream:

112.5 / 3 = 30 + x

x = 112.5 / 3 - 30

= 7.5 mph.

Answer:

Infinite decimals that do not repeat.

Step-by-step explanation:

Repeating decimals can be as fractions where the top and bottom are integers.

Examples: .3333333333333333333333333333333.... can be written as 1/3.

or .19191919191919191919..... can be written as 19/99.

Terminating decimals can also be written as fractions where the top and bottom are integers.

Examples:  .11=11/100 or .161=161/1000

Any number that can be written as a fraction where the top and bottom are integers (bottom integer not 0)

is a rational number.

Repeating decimals are infinite.  So what I think they mean by infinite here is numbers like [tex]\pi[/tex] or [tex]\sqrt{2}[/tex].  There are not rational.  They cannot be written as a fraction where the top and bottom are integers.

To find the total weight of the shipment where [tex]\frac{1}{5}[/tex] weighs 25 pounds, we use the equation [tex]\frac{1}{5}[/tex]W = 25 and solve for W, leading to a total weight of 125 pounds.

The question is asking us to write an equation that represents the situation where [tex]\frac{1}{5}[/tex] of a shipment of books weighs 25 pounds.

To find the total weight of the shipment, we should set this up as an equation where the total weight of the shipment is represented by W. Since [tex]\frac{1}{5}[/tex] of the shipment weighs 25 pounds, we can write the equation as [tex]\frac{1}{5}[/tex] W = 25.

To find the weight of the whole shipment, we need to multiply both sides of the equation by 5, which will give us

W = 125 pounds.

When converting units such as pounds to ounces, we use the unit equivalence 1 pound = 16 ounces.

If the weight of the books needed to be in ounces, we could convert 125 pounds by multiplying

125 x 16 = 2000 ounces

A football quarterback enjoys practicing his long passes over 40 yards. He misses the first pass 40% of the time. When he misses on the first pass, he misses the second pass 20% of the time. What is the probability of missing two passes in a row?

30%

Probability of missing two passes in a row is 0.08.

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

Given

Event E = A football player misses twice in a row.

P(E) = ?

Event X = Football player misses the first pass

P(X) = 0.4

Event Y = Football player misses just after he first miss

P(Y) = 0.2

Both the events are exclusive so the probability of occurring of these two events can be calculated by the formula:

P(E) = P(X).P(Y)

P(E) = 0.4*0.2

P(E) = 0.08

The expression 4h² + g has no common factors or recognizable factoring patterns, and is thus already in its simplest form; it cannot be factored further.

To factor completely the expression 4h² + g, we would look for common factors or recognizable patterns like the difference of squares, perfect square trinomials, or other factoring techniques. However, since 4h² and g have no common factor and the expression is not a difference or sum of cubes, or any other known factoring pattern, it cannot be factored further (assuming g is a constant). In other factoring scenarios, one might look for techniques like grouping, but that's not applicable here either. Therefore, the expression 4h² + g is already in its simplest, factored form as there are no common factors between the terms.

Answer:

Option B is correct.

Step-by-step explanation:

To check if the lines are parallel or perpendicular, we need to find the slope of lines AB and CD

A=(-8,1), B= (-2,4), C= (-3, -1), and D= (-6,5)

Slope of AB = y₂-y₁/x₂-x₁

Slope of AB = 4-1/-2-(-8)

Slope of AB = 3/-2+8

Slope of AB = 3/6

Slope of AB = 1/2

Slope of CD = y₂-y₁/x₂-x₁

Slope of CD = 5+1/-6-(-3)

Slope of CD = 6/-6+3

Slope of CD = 6/-3

Slope of CD = -2

Lines are parallel if Slope of AB = Slope of CD

Lines are perpendicular if Slope of Ab = -1/Slope of CD

So, Slope of AB = 1/2

Slope of CD = -2

So, LINE AB AND LINE CD ARE PERPENDICULAR

The answer is:

There is a total of 48 overripe fruit.

To calculate the number of pieces of overripe fruit we have, we need to write two equations to create a relationship between the number of apples and oranges.

Let be "x" the number of oranges, so:

[tex]Oranges=x\\Apples=x+32[/tex]

Now, we know that 3/5 of the oranges and 1/3 of the apples are overripe, so:

[tex]OverripeApples=\frac{1}{3}(x+32)\\\\OverripeOranges=\frac{3}{5}(x)[/tex]

Then, we have a condition that states that the number of overripe apples and overripe oranges is the same, so:

[tex]\frac{1}{3}(x+32)=\frac{3}{5}(x)[/tex]

[tex]\frac{1}{3}(x)+\frac{1}{3}(32)=\frac{3}{5}(x)[/tex]

[tex]\frac{1}{3}(32)=\frac{3}{5}(x)-\frac{1}{3}(x)[/tex]

[tex]\frac{1}{3}(32)=\frac{3x*3-1*x}{15}=\frac{9x-5*x}{15}=\frac{4x}{15}[/tex]

[tex]\frac{32}{3}=\frac{4x}{15}[/tex]

[tex]\frac{32*15}{3}=4x[/tex]

[tex]\frac{480}{3}=4x[/tex]

[tex]160=4x[/tex]

[tex]\frac{160}{4}=x[/tex]

[tex]40=x[/tex]

Therefore, we have that there are 40 oranges and 72 apples (40+32).

Now, calculating the number of overripe oranges and apples, we have:

[tex]OverripeApples=\frac{1}{3}(72)=24\\\\OverripeOranges=\frac{3}{5}(40)=24[/tex]

Hence, we have that there are 24 pieces of overripe oranges and 24 pieces of overripe apples. It means that there is a total of 48 overripe fruit.

Have a nice day!
