Answer:

The average of the numbers is the mean. After adding up all the numbers, divide by the number of numbers. You must add all the values in a data set together and divide by the number of values in the collection to determine the mean. The end product is yours!

I hope this helps! ^-^

Answer:

The mean is the average of a data set. You can find the mean by adding all of the numbers in the guven set of data and then divide by the total number of values in a set.

Step-by-step explanation:

for example:

2, 6, 8, 13, 16, 11, 7

add all of these numbers together

the total would be 63

there are 7 numbers in the data set so you would divide 63 by 7

the mean of the data set would be 9

Answer:

−4y+32

Step-by-step explanation:

Let's solve for x.

−9

x+8

Step 1: Flip the equation.

−9

x+8=y

Step 2: Add -8 to both sides.

−9

x+8+−8=y+−8

−9

x=y−8

Step 3: Divide both sides by (-9)/4.

−9

y−8

−9

−4y+32

I think this is the right answer.

X - (-20) = 5 _________________

tamaranim1 [39]

X - (-20) = 5

When you subtract a negative, change it to addition:

X + 20 = 5

Subtract 20 from both sides:

X = -15

Can i have help on this q plz

Answer:

No, they will need an additional £34 to stay the planned 10 nights.

Step-by-step explanation:

Attached screenshot of a spreadsheet.

The cost for 10 nights for the 2 people is £100.

The tent site rental (over 10m^2) for 10 nights is £150.

Savings for the two over the 9 weeks is £216.

They will need an additional £34 to camp as planned.

I suggest fibbing about the extra 0.5m^2 needed for the tent site. That will reduce the bill by £30, so they are only £4 short. Time to make a couple of friends.

Sandra’s lunch came to $12.84 plus 15% tax. What was the total cost of her lunch?

Nimfa-mama [501]

The total would be $14.77

because we will do 0.15x12.84 which is 14.766 but since this is money we round to the nearest hundredth , and that is $14.77
