if A and B are events with P(A) = 0.2, P(A OR B) = 0.61, and P(A AND B) = 0.19, find P(B).

Answers

Answer 1

Answer:

0.41

Step-by-step explanation:

p (A) = 0.2

P (B) =?

P (A or B) = 0.61

but P (A or B) = P (A) + P (B)

therefore P(B) = P (A or B) - P(B)

= 0.61 - 0.2

= 0.41

Higher Order Thinking Molly and five
friends picked a total of 300 oranges. If
they each picked the same number of
oranges, how many oranges did Molly
pick? Explain.

Answers

This is a professional level of thinking
Let’s evaluate
Molly and her five friends=6 humans
therefore it would be 300 oranges divided by 6 Humans=50

There are 50 oranges did Molly pick.

What is Division method?

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

Higher Order Thinking Molly and five friends picked a total of 300 oranges.

Now,

Since, Number of oranges = 300

And, Number of persons = 6

Hence, Number of oranges picked by each person = 300 / 6

                                                                                = 50

Thus, There are 50 oranges did Molly pick.

7. A card is randomly drawn from a standard deck of shuffled cards. What are the ODDS that the
card drawn is a Letter card?
A. 12.5%
B. 75%
C. 25%
D. 44%

Answers

There are 16 total "letter cards" (1 ace and 3 face cards per suit), so the probability of drawing a letter card is 16/52 = 4/13.

There are 52 - 16 = 36 non-letter cards, with probability 36/52 = 9/13 of being drawn.

Then the odds of drawing a letter card is the ratio of these probabilities,

(4/13) / (9/13) = 4/9 ≈ 44%

The first 9 positive odd integers are placed in the following 3 by 3 grid in such a way that the sum of the numbers in each row, column, and main diagonal is the same. Four of the numbers are shown and the other five numbers are represented by the letters A, B, C, D, and E.
Determine the values of A, B, C, D, and E.

Answers

Answer:

As stated in the question, the 9 numbers in the boxes are 1,3,5,7,9,11,13,15,17. Now, I have to find clues to see how to figure out each number.

First clue: Looking at the first row and the right column, they both have the letter B in it, but the first row also has A. Since they both have B, A+1=13+3. Simplified, A = 15. So, I have figured out the first value.

Second Clue: I can see that B,C, and D all have a relationship. Because for B, the rows and columns add up to 16 only, but for C, the middle row adds up to 18. Therefore, the value of B must be 2 more than C. For the leftmost column, I can see that the other two numbers would add to 20, and middle row would only add up to 18. This shows that C is 2 more than D.

Using this information, I can find all their values since I know the 9 numbers that are supposed to be in each box. To figure out their values, I have to find three consecutive odd numbers.

The only numbers I have left are 7,9,11, and 17.

Now I know that D=7, C=9, and B=11.

All that is left is the number 17, and the letter E.

E=17.

According to the question, I have to find the value of A+E.

Since A=15, and E=17, 15+17=32.

The value of A+E=32.

x²-6xy+11y²=3a²
x²-2xy-3y²=5a²​

Answers

Q: Given the simultaneous equations x²-6xy+11y²=3a², x²-2xy-3y²=5a²,derive an equation in x and y only, and hence solve the equations for x and y in terms of a.

Multiply the first equation by 5, the second by 3, and get 15^2 on both sides.

That means 5^2–30+55^2=3^2–6+9^2
which simplifies to:
^2–12+23^2=0
So,
=3±√ 13


Substitute each solution into either equation to get ^2 in terms of ^2.
and solve, then get , You should get either 0, 2 or 4 solutions.

In Mr. Kagame's Algebra 1 class, 7 students took the Unit 7 test. The class average was 78% (rounded). Six students' scores are known:HELPPP

Answers

The score of the seventh student will be given by:

[tex]x = 546 - a_1 - a_2 - a_3 - a_4 - a_5 - a_6[/tex]

What is the score of the last student?

So you know the scores of 6 of the students, let's define these as:

a₁, a₂, a₃, a₄, a₅, a₆.

And let's define x as the score of the 7th student.

We know that the average of the scores is 78% (rounded).

Then we can estimate the value of x using the average equation:

[tex]\frac{a_1 + a_2 + a_3 + a_4 + a_5 + a_6 + x}{7} = 78[/tex]

Now you can solve that for x, to get:

[tex]x = 78*7 - a_1 - a_2 - a_3 - a_4 - a_5 - a_6\\\\x = 546 - a_1 - a_2 - a_3 - a_4 - a_5 - a_6[/tex]

That is the equation to get the score of the seventh student as a function of the six known scores.

Please help!! A Ferris Wheel at a local carnival has a diameter of 150 ft. and contains 25 cars.

Find the approximate arc length of the arc between each car.

Answers

The arc length between each car is 18.84 ft

How to get the length of an arc?

For a section defined by an angle θ in a circle of radius R, the length of the arc is given by:

A = θ*R

A complete circle has an angle of 2π. Now, if the circle has 25 cars, then it has 25 sections, so the angle that defines each one of these sections is:

θ = (2π/25)

And the diameter of the circle is 150ft, so the radius (half of that) is:

R = (150ft)/2 = 75 ft

Then the length of the arc:

L = (2π/25)*75 ft = 18.84 ft
