# 20 points!!! plz help asapSuppose 10% of the flights arriving at an airport arrive early, 60% arrive on time, and 30%arrive late. Valerie used the random-number table to find the experimental probability that of 5flights, at least 2 will arrive late. The digit 0 represents flights arriving early. The digits 1,2,3,4, 5, and 6 represent flights arriving on time. The digits 7, 8, and 9 represent flights arrivinglate. Find the experimental probability that of 5 flights at least 2 will arrive late.A: 3/10B:2/5C: 9/20D: 11/20​

D. 11/20

Step-by-step explanation:

7, 8, and 9 represent late flights.  We want to count how many of the 20 trials have at least two of these digits.  Counting, we find that 11 of the 20 have at least two of these digits.

D. 11/20

What is 53=12(m - 3/4)- 16

We have such equation
53=12(m-3/4)-16
First we have to multiply 12 times every argument from the parethesis.
53=12*m*-3/4*12-16
53=12m-9-16
53=12m-25       /+25 (add 25 both sides)
53+25=12m
78=12m              /:12 (divide both sides by 12)
78:12=m

53=12(m-3/4)-16 is solved below:

First,
You must multiply 12 by m and 12 by -3/4(0.75) which is 12m and -9

Second,
12m - 9 - 16  ~~Combine Like Terms And It Will Become 12m + 25
53 = 12m + 25   ~~ You Must Subtract 25 From Both Sides Of The Equation And It Becomes 28 = 12m

Third,
28 = 12m    ~~divide both sides by 12
12     12      ~~ 12m/12 cancels out and 28/12 is 2

Giovanna,frances,and their dad each carried a 10-pound bag of soil into the backyard. after putting soil in the first flower bed, Giovanna's bag was 5/8 full, frances bag was 2/5 full, and their dads was 3/4 full . how many ounces of soil did they put in the first flower bed. solve create fraction word problems involving addition ,subtraction and multiplication please help

You need to find out how many pound of dirt they put in the 1st flower bed. 5/8+2/5+3/4. 1 pound = 16 ounces so what ever you get * 16 to get how ever many ounces. I hope this helped. :)

EXPLANATION

From the diagram, m∠PQR and m∠RQS are complementary.

This means that the two angles will add up to 90°.

Also, we were given that,

This implies that,

We put equation (2) into equation (1) to get,

Multiply through by 2 to get,

Divide through by 5.

To determine whether 10a-10c are true or false, you first need to know how to find the volume of the shoebox and the volume of the crate.

The equation for volume is l × w × h where l is the length, w is the width, and h is the height.

So, the volume of the shoebox is

V = l × w × h
V = 12 × 6 × 4
V = 288 cubic inches.

To find the volume of the crate, we simply multiply the volume of one shoebox by 20, as the crate holds 20 shoeboxes.

228 × 20 = 4560 cubic inches.

10a. Each shoebox has a volume of 22 cubic inches. False. The volume is 228 cubic inches.

10b. Each crate has a volume of about 440 cubic inches. False. The volume of each crate is 4560 cubic inches.

10c. If the crate could hold 27 shoeboxes, the volume of the crate would be about 7,776 cubic inches.

For this one, let's do some more math. Since we figured out the volume of a crate holding 20 shoeboxes is 4560 cubic inches, let's do the same thing to find the volume of a crate holding 27 shoeboxes.

228 × 27 = 6156 cubic inches.

False. The volume of a crate holding 27 shoeboxes would be 6156 cubic inches.

11 part A:

Each term above describes the term below, but the term below doesn't necessarily describe the term above.

The choice of terms is :trapezoid, triangle, rhombus, parallelogram

Before we do anything else, let's define our terms, as well as the ones used in the diagram.

Trapezoid - A four sided shape with a pair opposite parallel sides.
Triangle -
A shape with three sides.
Rhombus -
A shape with four equal straight sides.
Parallelogram -
A quadrilateral with two sets of parallel sides.
A four-sided shape with four angles.
Square -
A four-sided shape with all four sides the same length, and all four angles are the same size.

The first term is quadrilateral. From this, we can determine that the term triangle won't be used at all, as it's a three-sided figure, whereas a quadrilateralis a four-sided figure. This leaves trapezoid, rhombus, and parallelogramas our terms.

Atrapezoid is a quadrilateral, because it has four sides, but it can't be arhombusor parallelogram, so it goes in the first open box.

A parallelogram is a trapezoid, because it has a pair of opposite parallel sides, but it can't be a rhombus, because it doesn't necessarily have all equal sides, so it goes in the second open box.

A rhombus is a parallelogram, because it has two sets of parallel sides, and goes in the third open box.

So, from top box to bottom box, the order the term go is
Trapezoid
Parallelogram
Rhombus
Square

The sum of two consecutive integers is -15. If1 is added to the smaller integer and 2 is
subtracted from the larger integer, what is the
product of the two resulting integers?

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The product of the two resulting integers is 80.

### What is multiplication?

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.

Let the unknown integer be represented by x. Given that the sum of two consecutive integers is -15. Therefore, we can write,

x + (x+1) = -15

2x + 1 = -15

2x = -16

x = -8

Thus, the smaller integer is -9 and the larger integer is -8.

Now, If 1 is added to the smaller integer and 2 is subtracted from the larger integer.

Smaller Interger = -9 + 1 = -8

Larger Integer = -8 - 2 = -10

Further,  the product of the two resultingintegers is,

Product = -8 × -10

= 80

Hence, the product of the two resulting integers is 80.

-16

Step by Step Explanation:

-7 and -8 are consecutive integers.

-7+-8=-15

Add 1 to -7 and you get -6.

Subtract 2 from -8 and you get -10.

-10+-6=-16
