Given P(A)=0.8P(A)=0.8, P(B)=0.62P(B)=0.62 and P(A union B)=0.874P(A∪B)=0.874, find the value of P(A unionB)P(A∩B), rounding to the nearest thousandth, if necessary.
Use the inclusion/exclusion principle:
P(A ∩ B) = P(A) + P(B) - P(A ∪ B)
So
P(A ∩ B) = 0.8 + 0.62 - 0.874 = 0.546
proportions please help!
Answer:
[tex]\huge\boxed{x=-12}[/tex]
Step-by-step explanation:
In order to solve for this proportion, it’s important to note that this is basically just an equation. Like any other, our goal is to isolate x on one side.
Since we have two fractions, we can multiply both sides by both the denominators (x-3 and x-9). Since one will cancel out the other, we can just multiply both sides by the opposite denominator.
[tex]5(x-9)=7(x-3)\\\\5x-45=7x-21[/tex]
Now we can solve for x.
Subtract 5x from both sides:
[tex]-45=2x-21[/tex]
Add 21 to both sides:
[tex]-24=2x[/tex]
Divide both sides by 2:
[tex]x = -12[/tex]
Hope this helped!
Answer:
[tex]x= -12[/tex]
Step-by-step explanation:
Step 1: Write equation
[tex]\frac{5}{x-3} =\frac{7}{x-9}[/tex]
Step 2: Solve for x
Cross multiply: [tex]5(x-9)=7(x-3)[/tex]Distribute: [tex]5x-45=7x-21[/tex]Subtract 5x on both sides: [tex]-45=2x-21[/tex]Add 21 to both sides: [tex]-24=2x[/tex]Divide both sides by 2: [tex]-12=x[/tex]Rewrite: [tex]x= -12[/tex]Step 3: Check
Plug in x to verify it's a solution.
[tex]\frac{5}{-12-3} =\frac{7}{-12-9}[/tex]
[tex]\frac{5}{-15} =\frac{7}{-21}[/tex]
[tex]\frac{-1}{3} =\frac{-1}{3}[/tex]

The amount of fresh water left in the tanks of a nineteenth-century clipper ship is a linear function of the time since the ship left port, as shown in the table. Write an equation in point-slope form that represents the function. Then find the amount of water that will be left in the ship's tanks 60 days after leaving port.
1=3555
8=3240
15=2925
The line with slope m that contains the point (x1, y1) can be described by the equation
y − y1 = m(x − x1). In a real-world linear situation, you may have information that represents two points on the line. You can write an equation in point-slope form that represents the situation and use that equation to solve a problem.
Let x represent the number of days since the ship left port and y represent the number of gallons of water.
Two points on the line are (8,3240) and (1, 3555).
m =
3555 − 3240
1 − 8
=
315
−7
= −45
y − y1 = m(x − x1) Point-slope form.
y − 3555 = −45(x − 1) or y − 3240 = −45(x − 8)
y − 3555 = −45(60 − 1) Substitute for x.
y − 3555 = −2655 Simplify the right side.
y = 900 Solve for y.
900 gallons of water will be left after 60 days.
Hope this helped! (I didn't do it sooner cause I just did the quiz lol)
The equation of the function, in point-slope form, is given by:
[tex]y - 3555 = -45(x - 1)[/tex]
The amount of water left in the ship after 60 days is of 900 cubic units.
A line, in point-slope form, is represented by the following equation:
[tex]y - y_0 = m(x - x_0)[/tex]
In which:
m is the slope, which is the rate of change.The point is [tex](x_0, y_0)[/tex].We have two points: (1, 3555) and (8,3240).
Taking the first point, [tex]x_0 = 1, y = 3555[/tex].The slope is given by change in y divided by change in x, thus:[tex]m = \frac{3240 - 3555}{8 - 1} = -45[/tex]
Then
[tex]y - y_0 = m(x - x_0)[/tex]
[tex]y - 3555 = -45(x - 1)[/tex]
The amount after 60 days is y when x = 60, thus:
[tex]y - 3555 = -45(60 - 1)[/tex]
[tex]y = 900[/tex]
The amount of water left in the ship after 60 days is of 900 cubic units.

Catherine has 6 gallons of milk and uses 26/5 gallons to make cookies. What fraction of a gallon does she have left?
Answer:
4/5 gallons left
Step-by-step explanation:
make sure before subtracting that it has the same denominator.
Answer:2
Step-by-step explanation:
There are 256 Tsp in a gallon...so 1 Tsp = 1/256 gal. If one batch of cookies calls for 3 Tsp of milk, 5 batches will require 15 Tsp. So..... 15 / 256 ...

Write the equation of the line through the points (-3, 9) and (4, 2) in POINT-SLOPE FORM
Answer:
y-9=-1(x+3)
Step-by-step explanation:
The formula for point slope is y2-y1=m(x2-x1). So, we can use the values of the given points to solve the equation for m, or, the slope. We get an equation with the result of 2-9=m(4+3), which gives us the slope as -1. Now, substitute your xy values back in, to get the equation

A bakery sold apple pies for $12 and blueberry pies for $14 on Saturday sold a total of 41 pies and collected a total of $536 how many apple pies did you sell and how many blueberry pies do they sell
Answer:
22 blueberry pies and 19 apple pies.
Step-by-step explanation:
This can be solved using a system of equations. Your equation for amount of pies sold is x + y = 41, with x representing apple pies and y representing blueberry pies, and 41 being the total amount of pies sold. The other equation is for the amount of dollars earned from selling the pies, which is:
12x + 14y = 536 $12 per apple pie, $14 per blueberry pie, and a total of $536.
Let's first solve for x. The new equation would be x = 41 - y. Now, we plug this equation into the second equation.
12(41 - y) + 14y = 536 Here we substituted x for the equation we made.
429 - 12y +14y = 536
-12y +14y = 44 Here we moved the 429 to the other side by subtracting it from the left and right.
2y = 44
y = 22. Now we know that there was a total of 22 blueberry pies sold. Now we plug 22 pies back into the very first equation to find x, the amount of apple pies.
x + 22 = 41
x = 19. Now we know there was a total of 19 apple pies sold.
