Kevin has a spinner that has 10 equal sections and 2 sections of each color—red, blue, green, yellow, and purple. Kevin spins the spinner 180 times. Kevin determines about how many times the spinner will land on red or green, and his work is shown below.

P (red or green) = Number of red or green sections
-------------------------------------------------- x number of spins =
Total number of sections
2
------- (180) = 36
10

What mistake did Kevin make, if any?

A. Kevin has the formula reversed; it should be the total number of sections over
the number of red or green sections.

B. Kevin should have used a 4 in the numerator because there are 2 red sections
and 2 green sections.

C. Kevin should multiply by the number of sections in the spinner rather than the
total number of spins.

D. Kevin calculated the prediction correctly and did not make any mistakes.

The answer is 5s - 10t + 7
Following the order of operations (PEMDAS):

Step 1: simplify what’s inside the parentheses. Since we don’t know either variable s or t, we can’t simplify any further from what it already is.

Step 2: distribute the 5 to each of the terms inside the parentheses. This gets you (5s - 10t)

Step 3: arrange your final answer:

You can’t simplify any more unless you know one the the variables so you are left with this.

Answers

Answer:

6

Step-by-step explanation:

so if she has $65 and she spent 38.50 you find the difference which is   $26.50 then you divide it by 4 which is 6.62 so yes your right its 6 if you round it

Answer:

6 boxes.

Step-by-step explanation:

65 ≥ 38.50 + 4x    where x is the number of boxes of mints.

65 - 38.50  ≥ 4x

(65-38.40/ 4 ≥ x

x  ≤ 6.625

so the answer is 6 boxes.

Find the mean absolute deviation for the data set.

Answers

If the mean of the data set is 3.533. Then the mean absolute deviation for the data set will be 1.831.

How do find the mean absolute deviation of discrete data?

Suppose the data specified is of n sized as

[tex]\rm x_1, x_2, \cdots , x_n[/tex]

Let this data's mean will be μ

Then, the mean absolute deviation of this data is the mean of the absolute differences of the observations from the mean of the data they belong to.

It is calculated as:

[tex]\rm M.A.D = \dfrac{\sum_{i=1}^n|x_i - \mu|}{n}[/tex]

The data set is given below.

3, 5, 6, 3, 2, 2, 1, 0, 0, 4, 7, 4, 5, 5, 6

Then the mean of the data will be

Mean = (3 + 5 + 6 + 3 + 2  + 2 + 1 + 0 + 0 + 4 + 7 + 4 + 5 + 5 + 6)/15

Mean = 53/15

Mean = 3.533

Then the mean absolute deviation for the data set will be

[tex]\rm M.A.D = \dfrac{|3-3.533| + |5-3.533| + |6 - 3.533| + |3 - 3.533| + ...+|6-3.533|}{15}[/tex]

M.A.D. = 27.4665/15

Heres another brainly question giving 20pts!!

Answers

Answer:

We are given an area and three different widths and we need to determine the corresponding length and perimeter.  

The first width that is provided is 4 yards and to get an area of 100 we need to multiply it by 25 yards.  This would mean that our length is 25 yards and our perimeter would be 2(l + w) which is 2(25 + 4) = 58 yards.

The second width that is given is 5 yards and in order to get an area of 100 yards we need to multiply by 20 yards.  This would mean that our length is 20 yards and our perimeter would be 2(l + w) which is 2(20 + 5) = 50 yards.

The final width that is given is 10 yards and in order to get an area of 100 yards we need to multiply by 10.  This would mean that our length is 10 yards and our perimeter would be 2(l + w) which is 2(10 + 10) = 40 yards.

Therefore the field that would require the least amount of fencing (the smallest perimeter) is option C, field #3.

The bar graph shows the results of spinning a spinner 100 times. Use the bar graph to find the experimental probability of not spinning a 5.
PLEASE QUICK

Answers

Answer:

81%

Step-by-step explanation:

1.

We know that the probability of spinning a five is 19% since:

19/100 = 0.19 = 19%

However, we are looking for the probability of NOT spinning a five.  So, we will have to find the probability sum of the remaining numbers (1, 2, 3 and 4).

2.

- The probability of spinning a one is 20% since:

20/100 = 0.2 = 20%

- The probability of spinning a two is 18% since:

18/100 = 0.18 = 18%

- The probability of spinning a three is 22% since:

22/100 = 0.22 = 22%

- The probability of spinning a four is 21% since:

21/100 = 0.21 = 21%

3.

Now we will add all of these probabilities together to find the total probability of NOT spinning a five!

20% + 18% + 22% + 21% = 81%

Therefore, the probability of not spinning a five is 81%.

(While writing all of this down, I realized it was completely unnecessary)

Basically, the total probability of all of these numbers is equal to 100%.  The probability of spinning a five is 19% as we inquired above.  Therefore, all we need to do is subtract 19% from 100%!

100% - 19% = 81%

According to the graph, there is a 81% chance of not rolling the 5. If it is 19% 5’s then 100 - 19 = 81.

The temperature dropped 2 °F every hour for 12 hours. What was the total number of degrees the temperature changed in the 12 hours?

24 degrees
14 degrees
-24 degrees
-2 degrees

Answers

Answer:

-24 degrees

Step-by-step explanation:

To find the total change in temperature, multiply 12 by -2, since it dropped 2 degrees each hour for 12 hours.

12*(-2)

= -24

This means -24°F was the total number of degrees the temperature dropped.

Answer:

The question mentions the keyword, "temperature drops" meaning we need to alternatively subtract.

[tex]t = -2 * 12[/tex]

If we know that positive 2 times 12 is 24, we know -2 times 12 will be negative 24°, because any negative number times a positive number is always a negative number.
