A computer is used to generate passwords made up of numbers 0 through 9 and lowercase letters. The computer generates 400 passwords one character at a time.

A uniform probability model is used to predict the first character in the password.

What is the prediction for the number of passwords in which the first character is a vowel?

Round your answer to the nearest whole number.

Answer:

A≈50.27

Step-by-step explanation:

The formula for an Area of a circle is: A=πr(squared)

As was can the the diametter is 4, and the radius is half of the diameter, making the radius half of 4 whitch is 2. now just plug in two for R.

A= π4(squared)

4(squared) = 16

A= 16π

A= 50.27

Answer:

D. The range of the data set is 18.

Step-by-step explanation:

The question asks for the variability of the data.

That means it refers to the range of the data.

It shows how variable the data points in a set are.

Option D is the best answer.

Answer:

125600 cu ft total volumn

5.98 snow storms (or rounded up to 6)

Step-by-step explanation:

volumn =pi * radius^2 * height  (radius is 1/2 diameter of 40)

v= 3.14 * 20^2 * 100

v= 125600 cu ft

divide total volumn by 21,000 used per snow storm = 5.98

note; this is using 3.14 for pi

using pi key = 125663.7 total volumn and 5.98 snow storms stays the same

40 divided by (20 - 16)

40 divided by 4

10

answer is 10

Answer:

77.5 cm²

Step-by-step explanation:

We need to find the surface area of the rectangular prism.

Total surface area = 2(lw + wh + lh)

where:

Given dimensions:

[tex]\textsf{length}=\sf 6\dfrac12\:cm=6.5\:cm[/tex]

[tex]\textsf{width}=\sf 2\dfrac12\:cm=2.5\:cm[/tex]

[tex]\textsf{height}=\sf 2\dfrac12\:cm=2.5\:cm[/tex]

Substituting these value into the formula:

[tex]\begin{aligned}\textsf{Surface area} & =\sf 2(6.5 \cdot 2.5+2.5 \cdot 2.5+6.5 \cdot 2.5)\\ & = \sf2(16.25+6.25+16.25)\\ & = \sf 2(38.75)\\ & =\sf77.5\:cm^2 \end{aligned}[/tex]

Therefore, 77.5 cm² of fabric is needed to cover the weight.

If [tex]$l$[/tex] be the length of cuboid, [tex]$b$[/tex] be the breadth of cuboid and [tex]$h$[/tex] be the height of cuboid, then its total surface area (TSA) of cuboid is given by,

[tex]\;\longrightarrow\boxed{\tt{TSA = 2(lb + bh + lh)}}[/tex]

A cuboid is also known as rectangular prism.

We need to find the surface area of the cuboid or rectangular prism whose length, breadth and height are given.

Now by using the formula of surface area nd substituting the given values, we get the following results:

[tex]\implies\tt{Surface\;area = 2(6.5 \times 2.5 + 2.5 \times 2.5 + 6.5 \times 2.5)}\\[/tex]

[tex]\implies\tt{Surface\;area = 2(16.25 + 6.25 + 16.25)}\\[/tex]

[tex]\implies\tt{Surface\;area = 2(38.75)}\\[/tex]

[tex]\implies\boxed{\pmb{\tt{Surface\;area = 77.5}}}\\[/tex]

Hence, this is our required solution for this question.

Step-by-step explanation:

I got it through division but without remainders.

1. Divide the anwser with Does Mcdonalds Sell Burgers?

Division Multiplication Subtraction Bringdown.

Divide the number multiply closest to it subtract both numbers then bring down the next repeat until you get the answer.

2. Round up so there isnt a remiander.

Answer:

Step-by-step explanation:

The equation for the area of a circle is A=[tex]\pi[/tex][tex]r^{2}[/tex].

A=area

r=radius

We were given the diameter of the circle not the radius, so we need to solve for the radius.

Radius=(1/2)Diameter So,

(1/2)6=3mm

Now we can solve for the area.

3^2(3.1415926)=28.2743mm

Now round to two decimal places.

28.27mm

Answer:

Mean: 5.8

Median: 5

Range: 7

Step-by-step explanation:

Arrange the following data set from least to greatest.

2, 3, 3, 4, 4, 6, 9, 9, 9, 9

Mean: Finding the total average of the following data set.

Median: The middle number in the data set

Range: Subtracting the highest and the lowest value from the arranged data set.

Mean: Add all the numbers listed above and divide by the number of numbers in the set (10)

Median: Middle number. No middle number so I chose the number in between 4 and 6 which is 5.
Mode: Subtract smallest number from biggest number (9-2=7)

Answer:

∠ WXY = 127° is the ansewer, hope this helped!

Step-by-step explanation:

Answer:

3) 27 cubed

4) 72 cubed

5) 125 cubed

8) 27 cubed. 3 is the length, 3 is the width, and 3 is the height.

9) 72 cubed. 6 is the length, 3 is the width, and 4 is the height.

10) 125 cubed. 5 is the length, 5 is the width, and 5 is the height.

Step-by-step explanation

Here's what to show if your teacher requires for you to show your work.

3) 3 x 3 x 3 = 27

4) 6 x 3 x 4 = 72

5) 5 x 5 x 5 = 125

8) 3 x 3 x 3 = 27

9) 6 x 3 x 4 = 72

10) 5 x 5 x 5 = 125

These are the ones I'd suggest putting the up and down form on.

10) and 5) Also put 5 x 5 = 25.          4) and 9) Also put 6 x 3 = 18.

     2                                                        3

     25                                                      18

  x  5                                                     x 4  

   125                                                      72

Answer:

A. 2

Step-by-step explanation:

To add fractions we make them have a common denominator, since these fractions already do we don't have to worry about that. Next, we add up the nominators, so 9 + 5 which equals 14. So 14/7, now we simplify, since 7 is half of 14 when we simplify we get 2/1 or 2. So A would be the correct answer. Hope this helps!

Step-by-step explanation:

It is an equal step by step equation because the prism has equal sides, so you would just have to add all them up and too try to find the surface area, and you know how the bottom is ten so the top would be ten too.

angle 6 is 124

Step-by-step explanation:

(-3x+65)+(-6x+142)=180

-9x+207=180

-9x=-27

x=3

subsitute 3 for x

-6x+142

-6(3)+142

-18+142

124

Explanation:

For now, focus on the most expensive dishes only.

Add up the values and divide by 5 to get the mean.

(28+30+28+39+25)/5 = 150/5 = 30

The mean is 30

Subtract this mean from each of the prices. Use absolute value to ensure the difference is never negative.

This represents the distance each value is from the mean. For example, the value 25 is 5 units from the mean.

Then we average the set {2,0,2,9,5} to get the mean of (2+0+2+9+5)/5 = 18/5 = 3.6

The mean absolute deviation (MAD) for the most expensive dishes is 3.6

This is the average distance each value is from the mean. It's one measure to see how spread out a group of numbers is. The higher the MAD, the more spread out the values, and vice versa.

If you repeated those steps for the least expensive dishes, then you should get a MAD of 1.76

We see that the MAD of the cheaper dishes is much smaller than the expensive ones. This tells us the cheaper dishes are more clumped together, and closer to the mean. In other words, the cheaper dishes are more consistent in price. The expensive dishes are more spread out.
