Find The Probability Of Randomly Choosing Three Brown M&Ms In A Row From A Bagthat Contains 40 Brown

Answers

Answer 1

Answer:

The the probability of randomly choosing three brown M&Ms in a row and eat them immediately is 0.0014.

Step-by-step explanation:

Since we want to find the probability of randomly choosing three brown M&Ms in a row and they are eaten immediately after selecting them, this implies that we are dealing with a probability of without replacement.

Without replacement means the number of brown M&Ms and the total M&Ms decreases by one as we select one each in a row.

Therefore, we have:

Probability of selecting the first brown M&M without replacement = 40 / 350

Probability of selecting the second brown M&M without replacement = 39 / 349

Probability of selecting the third brown M&M without replacement = 38 / 348

Let B represents the the probability of randomly choosing three brown M&Ms in a row. Therefore, we have:

B = (40 / 350) * (39 / 349) * (38 / 348) = 0.114285714285714 * 0.111747851002865 * 0.109195402298851 = 0.00139455446243313

Approximating to 4 decimal places, we have:

B = 0.0014

Therefore, the the probability of randomly choosing three brown M&Ms in a row and eat them immediately is 0.0014.

Last year during the hurricane season, the amount of rain that fell on the Texas Gulf Coast in October was 14 inches, which was 3 1/2 times more than the rainfall during September of the same year. How much rain fell during the month of September?

Answers

Answer:

4in

Step-by-step explanation:

Given

Amount of rain that fell in October = 14in

If this value is 3 1/2times amount of rain that fell in September, we can express it mathematically as;

3 1/2 of September = 14

7/2 of x = 14

x is the amount of rain that fell in September

From the expression

7x/2 = 14

Cross multiply

7x = 14×2

7x = 28

Divide both sides by 7

7x/7 = 28/7

x = 4in

Hence the amount of rain that fell in September is 4in

32 students

Step-by-step explanation:

24 divided by .75 is 32

Based on the information given, there'll be 32 students.

Let the total number of students be represented by x.

From the information, it was stated that 75% of the students are boys and that there are 24 boys. Therefore, the total number of students will be:

75% × x = 24

0.75x = 24

x = 24/0.75

Answer:

Slope is -5/3, the y intercept is 5

Step-by-step explanation:

If you want to find cordinates you first have to solve the equation so that it is in the form mx+b=y

solve for y

5x+3y=15

-5x -5x

3y =-5x+15

3y/3 = -5x/3+15/3

y=-5/3x+5

or -5/3x+5=y

Now you know that the slope is -5/3 and the y intercept is 5

Start for 5 on the cordinate plain and go down 5 since it is negative and go to the right 3.

after you get to the bottom right of the graph you go back to 5 and just do the exact opposite of what you did above.

so go up 5 and go to the left 3 and continue until you get to the top left of the graph.

A rectangle is inscribed with its base on the x-axis and its upper corners on the parabola
y=2-x^2. What are the dimensions of such a rectangle with the greatest possible area?
width=?
height=?

Answers

Take x > 0. Then for 0 < x < √2, a rectangle circumscribed by the x-axis and the parabola y = 2 - x² has a length of 2x and a height of 2 - x², so its area is

A(x) = 2x (2 - x²)

Differentiate A with respect to x :

A'(x) = 2 (2 - x²) + 2x (-2x)

A'(x) = 4 - 6x²

Find the critical points:

4 - 6x² = 0

6x² = 4

x² = 4/6 = 2/3

x = √(2/3)

Check the sign of the second derivative at this point to confirm that it's a maximum:

A''(x) = -12x

The second derivative is negative for all x > 0, so x = √(2/3) is indeed a maximum.

So the rectangle with maximum area has dimensions

width/length = 2 √(2/3)

height = 2 - (√(2/3))² = 4/3

The cost of a bagel at Tim Horton’s is $0.99 and the cost of a large coffee is $1.29. If Derek purchases 4 more bagels than large coffees and spends $10.80 total, how many of each did he purchase?

Answers

Answer:

7 Bagels and 3 Large Coffee

Step-by-step explanation:

Represent Large Coffee with L and Bagel with B.

We have that:

[tex]0.99B + 1.29L = 10.80[/tex] ---- Amount spent

and

[tex]B = L + 4[/tex] ---- Quantity

Required

Determine the value of L and B

Substitute L + 4 for B in the first equation

[tex]0.99B + 1.29L = 10.80[/tex]

[tex]0.99(4 + L) + 1.29L = 10.80[/tex]

Open Bracket

[tex]3.96 + 0.99L + 1.29L = 10.80[/tex]

[tex]3.96 + 2.28L = 10.80[/tex]

Collect Like Terms

[tex]2.28L = 10.80 - 3.96[/tex]

[tex]2.28L = 6.84[/tex]

Solve for L

[tex]L = 6.84/2.28[/tex]

[tex]L = 3[/tex]

Recall that

[tex]B = 4 + L[/tex]

[tex]B = 4 + 3[/tex]

[tex]B = 7[/tex]
