Answer:

O(3,6)

Step-by-step explanation:

If the points are (-3,-6), this means -3 on the x axis and -6 on the y axis. if it is reflected in the y axis, the coordinates Change from either positive to negative or negative to positive. This means -3 is now 3 and -6 is now 6 hence the coordinates of (3,6)

Answer:

x*0.35

You would do x as the price as the sweater and then multiply it by 35% or 0.35.

Answer:

The answer is 132

Step-by-step explanation:

First, find the area wholely, 20x8 = 160. Then find the triangle which is 7x 8 divided by 2 is 28 and you subtract the whole are by the triangle which is 160 - 28 is 132

Answer:

The correct answer is 5 61/126!

Step-by-step explanation:

Leave a fraction alone

1 3/7

Find the Addend

9x3=27+5=32 = 32/9

Find the sum and simplify

1 3/7 + 32/9 = 691/126 = 5 61/126

To estimate the sum of the given terms: 13/7, 35/9, and 1/2, we can convert each term to a decimal number and then add them together. First, let's convert 13/7 to a decimal.

To do this, we divide [tex]13 by 7: 13 ÷ 7 = 1.857[/tex] Next, let's convert 35/9 to a decimal. Dividing 35 by 9 gives us: [tex]35 ÷ 9 = 3.889[/tex]  Finally, we convert 1/2 to a decimal by dividing 1 by 2:[tex]1 ÷ 2 = 0.5[/tex] Now that we have converted all the terms to decimals, we can add them together: [tex]1.857 + 3.889 + 0.5 = 6.246[/tex]

Therefore, the estimate of the sum of the given terms is 6.246. It's important to note that this is an estimate because we rounded the decimal values. If you need a more precise answer, you can use a calculator or longer division to get more decimal places. However, for most practical purposes, this estimate should suffice.

Step-by-step explanation:

If the store wants to give approximately half of the customers a 25% discount. They may need to adjust the discount criteria or randomly assign cards to customers to achieve the desired frequency.

The ratio of the number of outcomes in which a specified event occurs to the total number of trials, not in a theoretical sample space, but in an actual experiment, is the relative frequency or experimental probability of an event.

To determine the relative frequency for each discount, we need to count the number of customers who received each type of discount and divide by the total number of customers.

Let's create a table to organize the data:

Discount                  Card Label                Number of Customers

15%                            Even                             120

40%                            Odd > 6                     30

25%                           Other                            250

Total                                                     400

The relative frequency for each discount is given by:

Relative frequency of 15% discount: 120/400 = 0.3 or 30%

Relative frequency of 40% discount: 30/400 = 0.075 or 7.5%

Relative frequency of 25% discount: 250/400 = 0.625 or 62.5%

To determine whether this discount method is appropriate to give approximately half of the customers a 25% discount, we need to compare the observed frequency of the 25% discount with the desired frequency.

Half of the 400 customers is 200. If we want approximately half of the customers to receive the 25% discount, then the observed frequency of the 25% discount should be close to 200.

However, we see that the observed frequency of the 25% discount is 250, which is higher than the desired frequency.

The mode is the number that occurs the most in a data set.

Step-by-step explanation:

For example, let's say you have a data set of

97, 100, 96, 97, 100, 99, 97

Which are the test scores of the 7 smartest students in the 6th grade on their final exam.

Since there are more 97s than any other number in the set, 97 is the mode.

Answer:

the first one

Step-by-step explanation:

1. 1310 x 0.15 = 196.5

2. 1310 - 196.5 = 1113.5

3. 1113.5 - 310 = 803.5

4. 803.5 - 405 = 398.5

5. 398.5 divided by 2 = 199.25

Answer:797

Step-by-step explanation:the last one

Answer:

1 minute = 1080 - 960 = 120 m

5 minutes = 5400 - 4800 = 600 m

8 minutes = 8640 - 7680 = 960 m

Step-by-step explanation:

I think the easiest way is to just see how far they get at each time.  So I'm going to go one horse at a time.

16 m/s

1 minute = 60 seconds, every second is 16 meters so 16 m/s * 60 s = 960 m

5 minutes = 300 seconds so 16 m/s * 300 s = 4800 m

8 minutes = 480 seconds, 16 m/s * 480 s = 7680 m

I also want to point out that unites cancel out.  m/s * s is kinda like variables so the seconds being multiplied by m/s cancels witht eh seconds in the denominator.

Now the next horse

18 m/s

1 minute totals to 1080 m

5 minutes = 5400 m

8 minutes = 8640 m

Now we take the differences of each time

1 minute = 1080 - 960 = 120 m

5 minutes = 5400 - 4800 = 600 m

8 minutes = 8640 - 7680 = 960 m

Another way to do this is to take the difference of speed and then multiply that by the time.  so 18-16 = 2, then multiply each time by 2.  For me it just makes more intuitive sense the way I showed.

Answer:

1.4

Step-by-step explanation:

Step 1: We have to find the mean of the data set

The mean is the average or the sum of all the numbers divided by the amount of numbers there are.

3 + 1 + 4 + 4 + 4 + 1 + 1 + 2 + 1 + 5 = 26

There are 10 numbers in total so, 26/10 = 2.6

Step 2: We now know the mean so now we have to find the deviation

3 - 2.6, |1 - 2.6|, 4 - 2.6, 4 - 2.6... so on, (Note: this is just finding the distance between the numbers and the mean)

The results are, 0.4 + 1.6 + 1.4 + 1.4 + 1.4 + 1.6 + 1.6 + 0.6 + 1.6 + 2.4

This is equal to 14

Step 3: Lastly, we have to find the mean of the deviations

We know the mean is 14

We have 10 numbers

Therefore, 14/10 = 1.4 is the MAD

Answer:

See the graph attached. The red arrow represents the shaded area.

Explanation:

The inequality and its solution are given:

The solution set is all real numbers less than or equal to -50.

In a number line, the values less than -50 are all the values that are to the left of -50. Thus, the graph of a ≤ -50 must include -50 and the region to the left of it.

To indicate that - 50 is included, draw a solid point; then, shade the region since it to its left.
