The school day consists of six block classes with each being 60 minutes long. Lunch is 25 minutes. Transfer time between classes and/or lunch is 3 minutes. There is a fire drill scheduled to happen at a random time during the day.

What is the probability that the fire drill begins during lunch?

What is the probability that the fire drill begins durning transfer time?

If you are 2 hours late to school, what is the probability that you missed the fire drill?

Answers

Answer 1

In total the time is 685 min not counting the transfer time and 706 including the transfer time. The probability of lunch fire drill is 25/706. Transfer time in total is 21 min so the probability is 21/207. 2 hours is 120 min. so there is a 120/706 probability that you missed it.

Answer 2
The answer above is correct

A drawer has 9 pairs of white socks 7 pairs of black socks 6 pairs of brown socks and 3 pairs of blue socks you get dressed each morning in the dark in randomly reach into the sock drawer to get your socks after a day of wearing the socks you do not replace them until the weekend after you have done some laundry what is the probability that your sock selection goes in the following order for this week?
P(Black then white then white the brown then blue)=____

Answers

Answer:

0.0014 = 0.14%

Step-by-step explanation:

First we need to find the total number of pairs:

9 + 7 + 6 + 3 = 25 pairs

Then, we need to find the probability for each case:

First socks black: 7 pairs over 25: P1 = 7/25

Second socks white: 9 pairs over 24: P1 = 9/24 = 3/8

Third socks white: 8 pairs over 23: P1 = 8/23

Fourth socks brown: 6 pairs over 22: P1 = 6/22 = 3/11

Fifth socks blue: 3 pairs over 21: P1 = 3/21 = 1/7

The final probability will the the product of all probabilities above:

P = (7/25) * (3/8) * (8/23) * (3/11) * (1/7) = 0.0014 = 0.14%

Answer:

567/398475 in fraction or 0.0014229249 in decimal

Step-by-step explanation:

In the question, we are given these values

Total pair of socks = 25 pairs of socks

9 pairs of white socks

7 pairs of black socks

6 pairs of brown socks

3 pairs of blue socks

From the question, we can see that, this is probability without replacement.

Hence,

P(Black then white then white the brown then blue)=

7/25 × 9/24× 8/23 ×6/22 × 3/21

= 9072/6375600

= 567/398475

Therefore, the Probability of picking a Black socks then white socks then white socks , then brown socks and then blue socks = 567/398475 in fraction or 0.0014229249 in decimal

Answer: The answer is A. dilation :)

The transformation that produces a similar figure that is not congruent to the orginal figure is: A. dilation.

What is Dilation?

Dilation is a formm of transformation which involves the enlargement or reduction of an image to create a new image that is similar to the original image.

By implication, the new image has a different size but the same shape with the original image.

Dilation produces a figure that is similar but not congruent to the original figure.

We can describe 3x-2 as an expression how can we describe the parts of the expression that the arrows point to?

Answers

Answer:

If the arrow is pointing to the -2, that’s the constant.

If the arrow is pointing at x, that’s the variable.

If the arrow is pointing at 3, that’s the coefficient.

If arrow points to → 3x → it is a constant value multiplied by a variable.

If arrow points at → 2 → it is a constant number

What are expressions?

An expression in math is a sentence with a minimum of two numbers or variables and at least one math operation.

Given is the following expression3x - 2.

Parts of the expression are called its terms. Term of a expression can be a constant number, a variable or a constant value multiplied by a variable. The expression given is → 3x - 2.

If arrow points to → 3x → it is a constant value multiplied by a variable.

If arrow points at → 2 → it is called a constant number

Therefore, we can write -

If arrow points to → 3x → it is a constant value multiplied by a variable.

If arrow points at → 2 → it is a constant number

-x + 4y = 12

5x - 2y = -6

Answers

Answer:

(0, 3)

Step-by-step explanation:

Let's first eliminate x.  To do this, multiply all three terms of the first equation by 5:  

-5x + 20y = 60

5x -    2y  = -6

----------------------

         18y = 54, so that y = 3.

Substituting 3 for y in the first equation yields:

-x + 4(3) = 12, or -x = 0.  Thus, x = 0, and the solution is

(0, 3)

find the output y, when the input x, is 30.​

Answer:

A ( 1.5, 6 ), B ( 15, 33 ), Slope ⇒ 2

Step-by-step explanation:

We are given the line y - 2x = 3;

For the value 6, let us substitute this value in terms of y such to compute the value of x on the line y - 2x = 3;

6 - 2 * x = 3 ⇒ Subtract 6 on either side,

-2 * x = - 3 ⇒ Divide - 2 on either side of equation

x = 1 and 1 / 2 for y = 6,

Solution; A ( 1.5, 6 )

Now for the value 15, let us substitute this value in terms of x to compute the value of y on the line y = 2x - 3;

y - 2 * ( 15 ) = 3 ⇒ Multiply 15 by 2,

y - 30 = 3 ⇒ Add remaining terms,

y = 33 for x = 15,

Solution; B ( 15, 33 )

To determine the slope of this we could take the formula ( y2 - y1 )/ ( x2 - x1 ) for the two points we have derived or, for simplicity, take a look at the format of the equation;

y - 2x = 3 ⇒ Convert to point slope form, in format y = ax + b, where a ⇒ slope, and b ⇒ y - intercept

y = 2x + 3, ⇒ Solution; Slope ⇒ 2

9 is in the domain of fºg.

Answers

Answer:

9 is in the domain of f(g(x))

Step-by-step explanation:

f(g(x)) = -8*g(x) - 4

          = -8*( 7x+3) - 4

          = -56x - 24 - 4

          = -56x - 28

          = -28(2x + 1)

f(g(9)) = -28(2*9 + 1)

          = -28*19

          = -532

Since 9 can be plugged into the compound function, it is in the domain.
