it is 240 miles from boston to new york. If i drive at a speed of 50mph, how long will it take me to reach new york? how much more time would it take if my speed is 10mph faster?

a) the modal class interval is 0 - 2

b) the mean number of letters delivered = 3.2

In this question, we have been given the table that shows some information about the number of letters delivered to 50 houses.

a) To find the modal class interval

In given table, the maximum frequency is 25 and the corresponding class-interval is 0 - 2.

so, the modal class interval is 0 - 2

b) To find an estimate for the mean number of letters delivered.

Number of letters | mid-point | Number of |  (mid-point × frequency)

    delivered          |                  |     houses   |

      0 - 2                |       1          |        25        |               25

      3 - 4                |      3.5       |         12        |               42

      5 - 7                |        6        |         8          |               48

      8 - 10              |       9         |         5          |                45

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

                                  Total :            50                          160

Mean = 160 / 50

          = 3.2

Therefore, a) the modal class interval is 0 - 2

b) the mean number of letters delivered = 3.2

Answer:

0.28 pounds in each bag.

Step-by-step explanation:

There are 0.28 pounds in each snack-size bag.

In mathematics, divides left-hand operands into right-hand operands in the division operation. The primary purpose of the division is to generate equal groupings.

For example 4/2 = 2

We have been given that she bought 8.4 pounds of almonds. She divided them into 30 snack-size bags.

We have to determine the number of pounds in each bag.

The number of pounds in each bag = total quantity of almonds ÷ number of bags

The number of pounds in each bag = 8.4 pounds ÷ 30 bags

The number of pounds in each bag = 8.4/30

Apply the division operation, and we get

The number of pounds in each bag = 0.28 pounds

Thus, there are 0.28 pounds in each snack-size bag.

The sample space of the statement is 2.

"A sample space is a collection or a set of possible outcomes of a random experiment. The sample space is represented using the symbol, “S”. The subset of possible outcomes of an experiment is called events. A sample space may contain a number of outcomes that depends on the experiment. If it contains a finite number of outcomes, then it is known as discrete or finite sample spaces."

"The samples spaces for a random experiment is written within curly braces “ { } “. There is a difference between the sample space and the events."

The given statement is "Answering a false question"

Sample space of the following is S = {True, False}

Answer:

solving the expression [tex]\left(2\sqrt{3}-5\sqrt{7}\right)\:\left(2\sqrt{3}-5\sqrt{7}\right)[/tex] we get [tex]\mathbf{187+20\sqrt{21}}[/tex]

Step-by-step explanation:

We need to solve: [tex]\left(2\sqrt{3}-5\sqrt{7}\right)\:\left(2\sqrt{3}-5\sqrt{7}\right)[/tex]

We can write it as:

[tex]\left(2\sqrt{3}-5\sqrt{7}\right)\:\left(2\sqrt{3}-5\sqrt{7}\right)\\=\left(2\sqrt{3}-5\sqrt{7}\right)^2[/tex]

We can use formula: [tex]a^2-b^2=a^2-2ab+b^2[/tex]

[tex]=\left(2\sqrt{3})^2-2(2\sqrt{3})(-5\sqrt{7})+(-5\sqrt{7}\right)^2\\=4(3)+20\sqrt{3}\sqrt{7}+25(7)\\=12+20\sqrt{3\times 7}+175\\=187+20\sqrt{21}[/tex]

So, solving the expression [tex]\left(2\sqrt{3}-5\sqrt{7}\right)\:\left(2\sqrt{3}-5\sqrt{7}\right)[/tex] we get [tex]\mathbf{187+20\sqrt{21}}[/tex]

Answer:

Step-by-step explanation:

2−(x−10)=5x

Step 1: Simplify both sides of the equation.

2−(x−10)=5x

2+−1(x−10)=5x(Distribute the Negative Sign)

2+−1x+(−1)(−10)=5x

2+−x+10=5x

(−x)+(2+10)=5x(Combine Like Terms)

−x+12=5x

−x+12=5x

Step 2: Subtract 5x from both sides.

−x+12−5x=5x−5x

−6x+12=0

Step 3: Subtract 12 from both sides.

−6x+12−12=0−12

−6x=−12

Step 4: Divide both sides by -6.

−6x−6=−12−6

x=2

Answer:

x=2

Answer:

x = 2

Step-by-step explanation:

2-(x-10) = 5x

distribute the - into the  (  )

2 -x + 10 = 5x

combine like terms

12 - x = 5x

     +x    +x

12 = 6x

divide both sides by 6

x = 2

Step-by-step explanation:

To find the radius find the distance between (4,0) and (4,8). The radius is 8. Then multiply by 2 to find out the diameter.

Answer:

16

Step-by-step explanation:

Graphing the two points, you see that (4,8) is 8 points away from (4,0) - the center of the circle.

Knowing that 8 would be the radius, and that diameter = 2(radius), multiply the radius by two to find the diameter.

diameter = 2(8)

diameter = 16

The sample percentage (p) represents the proportion of people in a sample who have a particular attribute or trait. The correct option is A.

The sample percentage (p) represents the proportion of people in a sample who have a particular attribute or trait. Divide the number of persons (or objects) who have the characteristic of interest by the total number of people (or items) in the sample to get the sample proportion.

Given there are 36 successful outcomes in a sample with a size of 80. Therefore, the sample proportion is,

Sample proportion = 36/80 = 0.45

Hence, the correct option is A.

Answer:

C

Step-by-step explanation:

You need to equal the denominator (x — 5 = 0)

When you leave the x alone the result is x=5, so the number outside the “house” is five.

Then you look at the equation in the numerator and you place the coefficients in order and with their signals.

X^2 the coefficient is 1

-3x the coefficient is -3
