How many 5 number zip codes can be created if the first number cannot be one, three, or five, and each of the numbers must be different? (Hint: It may be helpful to list out the digits first.)

Answers

Answer 1

Answer:

21,168

Step-by-step explanation:

Given:

Available digits:  0, 1, 2, 3, 4, 5, 6, 7, 8, 9  (10 digits)Restrictions:  first number can only be 0, 2, 4, 6, 7, 8, 9  (7 digits)Each of the 5 numbers must be different

Therefore:

1st number:  0, 2, 4, 6, 7, 8, 9  (7 digits)2nd number:  0, 1, 2, 3, 4, 5, 6, 7, 8, 9  (10 digits)3rd number:  0, 1, 2, 3, 4, 5, 6, 7, 8, 9  (10 digits)4th number:  0, 1, 2, 3, 4, 5, 6, 7, 8, 9  (10 digits)5th number:  0, 1, 2, 3, 4, 5, 6, 7, 8, 9  (10 digits)

As each of the numbers must be different, the choices are:

1st number:  7 choices2nd number:  10 - 1 = 9 choices
(since we can't repeat the 1st number)3rd number:  10 - 2 = 8 choices
(since we can't repeat the 1st and 2nd numbers)4th number:  10 - 3 = 7 choices
(since we can't repeat the 1st, 2nd & 3rd numbers)5th number: 10 - 4 = 6 choices
(since we can't repeat the 1st, 2nd, 3rd & 4th numbers)

Therefore, the total number of combinations is:

7 × 9 × 8 × 7 × 6 = 21,168

PLSS HELPPP!!!!!! HURRYYY!!! THXXX!!!Kylie compared the price per pound of two types of apples at her grocery store. She used the equation y=0.85x to represent y, the total cost in dollars of x pounds of apple A. She entered into the table below the cost of some weights of apple B.




What is the difference in the price per pound between apple A and apple B?


A

$0.40


B

$0.85


C

$1.25


D

$2.10

Answers

Answer:

Choice A is the correct answer.

Step-by-step explanation:

We can compare the prices by taking one of the weight values from the table for apple B and plug it into the equation for apple A.

For example, let's take 4 from the table. The equation would look like this:

y = 0.85(4) = $3.40.

This is the price of 4 pounds of apple A. However, the price for 4 pounds of apple B is $5.00.

5.00 - 3.40 = $1.60. This is the difference in price between 4 pounds of apple A and 4 pounds of apple B. If we want to find the difference per 1 pound, just divide 1.60 by 4.

1.60 / 4 = $0.40.

Therefore, the answer is Choice A.

Which sector makes an angle closest to 40 degrees (Your answer should be a color word.)

Answers

The answer would be the Blue sector.

Because 15% of 360° is 37.2

37.2 is only 2.8 away from 40 making it the closest!

40° is one-ninth of 360°. As a percent, this is equal to

What is the approximate area of shadad region? use 3.14 π

A. 16.86
B. 19
C.18.43
D.23.14

Answers

Answer: A) 16.86 square inches

Step-by-Step Explanation:

Area of Shaded Area will be the Area of the Rectangle (Total Area) minus the Area of the Circle.

Finding Area of Circle :-

Radius (r) = 1 in
Area = πr^2

Therefore,
= πr^2
= π * r * r
= 3.14 * 1 * 1
=> 3.14

Area = 3.14 in^2

Finding Area of Rectangle (Total Area) :-

Length (l) = 5 in
Breadth (b) = 4 in
Area = l * b

Therefore,
= l * b
= 5 * 4
=> 20

Area = 20 in^2

Finding Area of Shaded Region :-

Area of Rectangle - Area of Circle

Therefore,
= 20 - 3.14
= 16.86

Area = 16.86 in^2
16.86 square inches,

Explanation

5in • 4in - (1 squared • 3.14)

Write an equation that represents the situation.

the answer is 3 times q + 7 = 40 because there are 4 sides and 3 of the sides are equal as one of them is 7 so you add 7 to the total amount after multiplying q three times
Q = 11. 3q + 7 = 40. Since the q sides are the same length and the total perimeter is 40, you use the equation and get 11.

5. Is it possible to determine a missing percentage in a circle graph? Yes, we can always assume the total percentage is 100 so you add your given percentages together and then subtract that total from 100 to find the missing percentage.

How would you use the coordinate plane to determine the area of Figure 3 on the graph below?

Answers

To identify the area of the figure, the amount it occupies on the x-axis and on the y-axis must be identified, and finally it must be multiplied.

How to identify an Area with the Coordinate Plane?

To identify the area of figure 3, its extension must first be identified on one of the axes, for example, the x-axis, where its extension is:

Extension of the figure on the x axis = 2 (since it goes from 7 to 9).

Then its extension on the y-axis must be identified, which is:

Extension of the figure on the axis y = 5 (since it goes from 5 to 10)

Finally, the two visualized extensions must be multiplied to obtain the area of the figure:

Figure area = Extension x * Extension yArea of the figure = 2 * 5Figure area = 10

Units are not used as they are not specified in the drawing or information, but could be square inches or square feet.

HELP PLEASEE and thank youuu Find and interpret the mean absolute deviation of the data. 94,86,95,99,88,90 The mean absolute deviation is____. The values differ from the mean by an average of_____.

Answers

Step-by-step explanation: First of all the first step to find the mean absolute deviation you need to add 94, 86, 95, 99, 88 and 90 and then divide 552 which is the result that you get when you add by 6 getting an answer of 92. Second you need to find the distance or deviation but remember put those signs of absolute value when you find the answer.

remember the rule of absolute value which is that all numbers are always positive.

94-92= |2|

86 - 92= |6|

95-92=|3|

99-92=|7|

88-92=|4|

90-92=|2|

The final steps are to find the mean of the results you get when you subtract the deviation.

2+6+3+7+4+2= 24/6=4 is the absolute deviation

The mean absolute deviation is 4. The values differ from the mean by an average of 4.
